Great Panther Files NI 43-101 Technical Report for the Tucano Gold Mine and Provides Update on Exploration Strategy and Programs for 2021 – PRNewswire
TSX: GPR | NYSE American: GPL
(All dollar amounts expressed in US dollars unless otherwise noted)
VANCOUVER, BC, Jan.29, 2021 /PRNewswire/ - Great Panther Mining Limited (TSX: GPR) (NYSE-A: GPL) ("Great Panther" or the "Company") announces today it has filed the "Technical Report on the 2020 Mineral Reserves and Mineral Resources of the Tucano Gold Mine, Amapa State, Brazil" ("Technical Report"). The Technical Report supports the Company's updated Mineral Reserve and Mineral Resource estimate ("MRMR") for Tucano announced by news release onDecember 15, 2020.
The Technical Report has an effective date ofSeptember 30, 2020, and is available on SEDAR at http://www.sedar.comand on the Company's website at http://www.greatpanther.com,and will be filed on EDGAR as soon as practicable at http://www.sec.gov.
2021 Exploration Programs and Exploration Strategy Update
"Our 2020 exploration programs were successful in extending the existing open pit mine life at Tucano and adding significant resources to our mineral inventory for the Guanajuato Mine Complex", stated Rob Henderson, President and CEO. "2021 will represent a significant increase in our exploration efforts with a planned record of 90,000 metres of drilling representing a $13 million investment. Our key objectives will be to continue to extend the Tucano open pit mine life, further prove up the underground with a view to extending the high-grade zones, and make meaningful inroads into key targets in the expansive Tucano regional land package. Building on our 2020 exploration success in Mexico will also be a key focus for this year."
The Great Panther exploration strategy is built on the objective of result driven exploration programs leading to resource replacement and near-mine growth, and longer-term organic growth through regional exploration.
The following outlines Great Panther's 90,000 metres ("m") drilling program for 2021.

Planned 2021 drilling metres and expenditure for Other Projects (described below) are new disclosures. The Company previously provided planned 2021 drilling expenditures for the Tucano Mine and Mexican operating mines in its January 14, 2021 press release which provided production and cost guidance for these mines.
Tucano (Brazil)
Great Panther's strategy for Tucano is to explore and grow the gold resource potential of the tenement portfolio, covering an almost 2,000 square kilometres ("km2") portion of the Vila Nova Greenstone Belt (the "Belt"). In 2021, five drill rigs are planned to complete 60,000m of drilling and over 500km of regional soil sampling will identify high priority regional targets.
The Tucano Gold Mine is host to a 7-kilometer-long trend of gold deposits surrounded by the large, near 2,000km2 tenement package controlled by Great Panther. Despite the long history of the deposit, discovered in the late 1990's and with first production in 2005, little exploration or resource drilling has been carried out outside the Tucano mine trend. A number of targets were defined in aero-geophysical and regional geochemical surveys in the late 1990's and Great Panther plans include carrying exploration of those viewed as the highest potential targets within reasonable proximity of the current mining operations.
Open Pit Resource replacement and expansion. The 24,000m combined Reverse Circulation ("RC") and Diamond Drilling ("DD") campaign is focused on near-mine targets including TAPC, Urso and Torres, as well as testing of several geochemical anomalies associated with the mine sequence that have not been evaluated.
Urucum underground. The current underground MRMR incorporates just part of the anomalous trend below the Urucum pits. There are a number of high-grade mineralized zones suggested by the modelling of the historical drilling. The 8,000m diamond drilling program is focused on upgrading one of the known high-grade zones at Urucum North while testing another zone at Urucum Central. The extent of these high-grade zones is important in determining the placement of the primary decline that will be used to access the mining areas.
Regional target drilling. A total of 28,000m has been planned for fast-track evaluation of key targets such as Mutum, Saraminda and Lona Amarela using Auger, Rotary Air Blast ("RAB") and RC drilling programs plus multi-element soil geochemistry. Initial orientation studies in 2020 and currently underway at Mutum suggest the interpretation of detailed soil sampling using multi-element geochemical analyses will allow for the skipping of the auger drilling step and going straight to RAB or RC drilling, which is expected to accelerate the start of drill permitting processes by four to eight months. A detailed soil grid is currently being opened to cover the 5km long Mutum gold trend and RAB and RC programs are being prepared for Saraminda and Lona Amarela. Mutum, Saraminda and Lona Amarela are within 15 km of the of the existing mine operations.
New target generation. Having defined the regional structural model associated with the mineralization events, Great Panther has prioritized high potential exploration corridors within the 2000km2 area of interest. It has initiated a program of regional multi-element soil sampling over these corridors with the intention of defining new targets within the Belt and prioritizing these targets using the combination of the geochemistry and existing regional aero-geophysical data.
Mexico
San Ignacio.Exploration efforts continue with 5,000m of fill-in surface drilling planned along the Purisima veins south of the development of the San Pedro ramp, deeper in the Purisima/Purisima alto vein system and continue testing for Au-Ag mineralization along 1.1km of Purisima vein north from the old San Ignacio shaft.
Guanajuato. A concerted effort of sampling and geological mapping in accessible parts of the historical mining areas is near completion and will be followed by a planned 10,000m of underground drilling on the most prospective areas, including along the north side of Valenciana, between Valenciana and Cata, and in the Pozos, Promontorio, and Guanajuatito areas. The 2020 exploration efforts more than doubled the known Inferred Mineral Resource estimate. See the Company's news release dated November 23, 2020 and the related technical report filed on December 23, 2020 with an effective date of July 31, 2020 for more details.
Topia. 5,000 m exploration surface drilling are planned focussed on defining new Mineral Resources in six areas along the strike and down-dip extents of present mining efforts.
Other Projects
Other Projects. These may include the Plomo gold project in Sonora ("Plomo"), El Horcn which has proximity to the GMC, or Coricancha in Peru. The $2.0 million budgeted for these projects will be allocated on the basis of a number of factors including potential for return on investment, access and availability of resources, community and permitting considerations. Plans for Plomo, for example, will see detailed geological / alteration / structural mapping to confirm an earlier geological interpretation from 2012, before any surface drill testing. El Horcon drilling will be subject to a successful study on the addition of a zinc concentrate flotation for the Guanajuato plant. Drilling for Coricancha would focus on expanding readily accessible high grade Mineral Resources along the Constancia, Wellington, and Escondida veins and is subject to achieving acceptable community agreements for access.

CAUTIONARY NOTE TO UNITED STATES INVESTORS CONCERNING ESTIMATES OF MEASURED, INDICATED AND INFERRED RESOURCES
The Company prepares its disclosure in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Terms relating to Mineral Resources in this news release are defined in accordance with NI 43-101 under the guidelines set out in the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards for Mineral Resources and Mineral Reserves 2014 (CIM Definition Standards).
The United States Securities and Exchange Commission (the "SEC") has adopted amendments effective February 25, 2019 (the "SEC Modernization Rules") to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the United States Securities Exchange Act of 1934. The SEC Modernization Rules have replaced SEC Industry Guide 7, which will be rescinded following a transition period and after the required compliance date of the SEC Modernization Rules.
As a result of the adoption of the SEC Modernization Rules, the SEC will now recognize estimates of "Measured Mineral Resources", "Indicated Mineral Resources" and "Inferred Mineral Resources", which are defined in substantially similar terms to the corresponding CIM Definition Standards. In addition, the SEC has amended its definitions of "Proven Mineral Reserves" and "Probable Mineral Reserves" to be substantially similar to the corresponding CIM Definition Standards.
United States investors are cautioned that while the foregoing terms are "substantially similar" to corresponding definitions under the CIM Definition Standards, there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. Accordingly, there is no assurance any Mineral Resources that the Company may report as "Measured Mineral Resources", "Indicated Mineral Resources" and "Inferred Mineral Resources" under NI 43-101 would be the same had the Company prepared the resource estimates under the standards adopted under the SEC Modernization Rules.
United States investors are also cautioned that while the SEC will now recognize "Measured Mineral Resources", "Indicated Mineral Resources" and "Inferred Mineral Resources", investors should not assume that any part or all of the mineral deposits in these categories would ever be converted into a higher category of Mineral Resources or into Mineral Reserves. Mineralization described by these terms has a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. Accordingly, investors are cautioned not to assume that any "Measured Mineral Resources", "Indicated Mineral Resources", or "Inferred Mineral Resources" that the Company reports are or will be economically or legally mineable.
Further, "Inferred Resources" have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, United States investors are also cautioned not to assume that all or any part of the Inferred Resources exist. In accordance with Canadian securities laws, estimates of "Inferred Mineral Resources" cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43-101.
In addition, disclosure of "contained ounces" is permitted disclosure under Canadian regulations; however, the SEC has historically only permitted issuers to report mineralization as in place tonnage and grade without reference to unit measures.

Stem Cell Study Illuminates the Cause of a Devastating Inherited Heart Disorder – Newswise
Newswise PHILADELPHIAScientists in the Perelman School of Medicine at the University of Pennsylvania have uncovered the molecular causes of a congenital form of dilated cardiomyopathy (DCM), an often-fatal heart disorder.
This inherited form of DCM which affects at least several thousand people in the United States at any one time and often causes sudden death or progressive heart failure is one of multiple congenital disorders known to be caused by inherited mutations in a gene called LMNA. The LMNA gene is active in most cell types, and researchers have not understood why LMNA mutations affect particular organs such as the heart while sparing most other organs and tissues.
In the study, published this week in Cell Stem Cell, the Penn Medicine scientists used stem cell techniques to grow human heart muscle cells containing DCM-causing mutations in LMNA. They found that these mutations severely disrupt the structural organization of DNA in the nucleus of heart muscle cells but not two other cell types studied leading to the abnormal activation of non-heart muscle genes.
Were now beginning to understand why patients with LMNA mutations have tissue-restricted disorders such as DCM even though the gene is expressed in most cell types, said study co-senior author Rajan Jain, MD, an assistant professor of Cardiovascular Medicine and Cell and Developmental Biology at the Perelman School of Medicine.
Further work along these lines should enable us to predict how LMNA mutations will manifest in individual patients, and ultimately we may be able to intervene with drugs to correct the genome disorganization that these mutations cause, said study co-senior author Kiran Musunuru, MD, PhD, a professor of Cardiovascular Medicine and Genetics, and Director of the Genetic and Epigenetic Origins of Disease Program at Penn Medicine.
Inherited LMNA mutations have long puzzled researchers. The LMNA gene encodes proteins that form a lacy structure on the inner wall of the cell nucleus, where chromosomes full of coiled DNA are housed. This lacy structure, known as the nuclear lamina, touches some parts of the genome, and these lamina-genome interactions help regulate gene activity, for example in the process of cell division. The puzzle is that the nuclear lamina is found in most cell types, yet the disruption of this important and near-ubiquitous cellular component by LMNA mutations causes only a handful of relatively specific clinical disorders, including a form of DCM, two forms of muscular dystrophy, and a form of progeria a syndrome that resembles rapid aging.
To better understand how LMNA mutations can cause DCM, Jain, Musunuru, and their colleagues took cells from a healthy human donor, and used the CRISPR gene-editing technique to create known DCM-causing LMNA mutations in each cell. They then used stem cell methods to turn these cells into heart muscle cells cardiomyocytes and, for comparison, liver and fat cells. Their goal was to discover what was happening in the mutation-containing cardiomyocytes that wasnt happening in the other cell types.
The researchers found that in the LMNA-mutant cardiomyocytes but hardly at all in the other two cell types the nuclear lamina had an altered appearance and did not connect to the genome in the usual way. This disruption of lamina-genome interactions led to a failure of normal gene regulation: many genes that should be switched off in heart muscle cells were active. The researchers examined cells taken from DCM patients with LMNA mutations and found similar abnormalities in gene activity.
A distinctive pattern of gene activity essentially defines what biologists call the identity of a cell. Thus the DCM-causing LMNA mutations had begun to alter the identity of cardiomyocytes, giving them features of other cell types.
The LMNA-mutant cardiomyocytes also had another defect seen in patients with LMNA-linked DCM: the heart muscle cells had lost much of the mechanical elasticity that normally allows them to contract and stretch as needed. The same deficiency was not seen in the LMNA-mutant liver and fat cells.
Research is ongoing to understand whether changes in elasticity in the heart cells with LMNA mutations occurs prior to changes in genome organization, or whether the genome interactions at the lamina help ensure proper elasticity. Their experiments did suggest an explanation for the differences between the lamina-genome connections being badly disrupted in LMNA-mutant cardiomyocytes but not so much in LMNA-mutant liver and fat cells: Every cell type uses a distinct pattern of chemical marks on its genome, called epigenetic marks, to program its patterns of gene activity, and this pattern in cardiomyocytes apparently results in lamina-genome interactions that are especially vulnerable to disruption in the presence of certain LMNA mutations.
The findings reveal the likely importance of the nuclear lamina in regulating cell identity and the physical organization of the genome, Jain said. This also opens up new avenues of research that could one day lead to the successful treatment or prevention of LMNA-mutations and related disorders.

Stem Cell Study Illuminates the Cause of a Devastating Inherited Heart Disorder - Newswise
Merck Receives Positive EU CHMP Opinion for Expanded Approval of KEYTRUDA (pembrolizumab) in Certain Patients With Relapsed or Refractory Classical…
KENILWORTH, N.J.--(BUSINESS WIRE)--Merck (NYSE: MRK), known as MSD outside the United States and Canada, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending approval of an expanded label for KEYTRUDA, Mercks anti-PD-1 therapy. The opinion is recommending KEYTRUDA as monotherapy for the treatment of adult and pediatric patients aged 3 years and older with relapsed or refractory classical Hodgkin lymphoma (cHL) who have failed autologous stem cell transplant (ASCT) or following at least two prior therapies when ASCT is not a treatment option.
This recommendation is based on results from the pivotal Phase 3 KEYNOTE-204 trial, in which KEYTRUDA monotherapy demonstrated a significant improvement in progression-free survival (PFS) compared with brentuximab vedotin (BV), a commonly used treatment. KEYTRUDA reduced the risk of disease progression or death by 35% (HR=0.65 [95% CI, 0.48-0.88]; p=0.00271) and showed a median PFS of 13.2 months versus 8.3 months for patients treated with BV. The recommendation is also based on supportive data from an updated analysis of the KEYNOTE-087 trial, which supported the European Commissions (EC) approval of KEYTRUDA for the treatment of adult patients with relapsed or refractory cHL who have failed ASCT and BV or who are transplant ineligible and have failed BV. The CHMPs recommendation will now be reviewed by the EC for marketing authorization in the European Union (EU), and a final decision is expected in the first quarter of 2021. If approved, this will be the first pediatric indication for KEYTRUDA in the EU.
This positive opinion reinforces the importance of KEYTRUDA for certain adult and pediatric patients with relapsed or refractory classical Hodgkin lymphoma in the European Union, said Dr. Vicki Goodman, vice president, clinical research, Merck Research Laboratories. We look forward to the decision by the European Commission and will continue to expand our clinical development program in blood cancers with KEYTRUDA and our recently acquired investigational therapies to help address the unmet needs of patients.
Merck is studying KEYTRUDA across hematologic malignancies through a broad clinical program, including multiple registrational trials in cHL and primary mediastinal large B-cell lymphoma and more than 60 investigator-initiated studies across 15 tumors. In addition to KEYTRUDA, Merck is evaluating two clinical-stage assets for the treatment of patients with hematologic malignancies: MK-1026 (formerly ARQ 531), a Brutons tyrosine kinase inhibitor, and VLS-101, an antibody-drug conjugate targeting ROR1.
About KEYNOTE-204
KEYNOTE-204 (ClinicalTrials.gov, NCT02684292) is a randomized, open-label, Phase 3 trial evaluating KEYTRUDA monotherapy compared with BV for the treatment of patients with relapsed or refractory cHL. The primary endpoints are PFS and overall survival (OS), and the secondary endpoints include objective response rate (ORR), complete remission rate (CRR) and safety. The study enrolled 304 patients, aged 18 years and older, who were randomized to receive either:
About Hodgkin Lymphoma
Hodgkin lymphoma is a type of lymphoma that develops in the white blood cells called lymphocytes, which are part of the immune system. Hodgkin lymphoma can start almost anywhere most often in lymph nodes in the upper part of the body, with the most common sites being in the chest, neck or under the arms. Worldwide, there were approximately 83,000 new cases of Hodgkin lymphoma diagnosed, and more than 23,000 people died from the disease in 2020. In the EU, there were nearly 20,000 new cases of Hodgkin lymphoma diagnosed, and nearly 4,000 people died from the disease in 2020. Classical Hodgkin lymphoma accounts for more than nine in 10 cases of Hodgkin lymphoma in developed countries.
About KEYTRUDA (pembrolizumab) Injection, 100 mg
KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the bodys immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.
Merck has the industrys largest immuno-oncology clinical research program. There are currently more than 1,300 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

Selected Important Safety Information for KEYTRUDA
Severe and Fatal Immune-Mediated Adverse Reactions
KEYTRUDA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or the programmed death ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions.
Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of antiPD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.
Withhold or permanently discontinue KEYTRUDA depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose adverse reactions are not controlled with corticosteroid therapy.
Immune-Mediated Pneumonitis
KEYTRUDA can cause immune-mediated pneumonitis. The incidence is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were required in 67% (63/94) of patients. Pneumonitis led to permanent discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9% (26) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Pneumonitis resolved in 59% of the 94 patients.
Pneumonitis occurred in 8% (31/389) of adult patients with cHL receiving KEYTRUDA as a single agent, including Grades 3-4 in 2.3% of patients. Patients received high-dose corticosteroids for a median duration of 10 days (range: 2 days to 53 months). Pneumonitis rates were similar in patients with and without prior thoracic radiation. Pneumonitis led to discontinuation of KEYTRUDA in 5.4% (21) of patients. Of the patients who developed pneumonitis, 42% of these patients interrupted KEYTRUDA, 68% discontinued KEYTRUDA, and 77% had resolution.
Immune-Mediated Colitis
KEYTRUDA can cause immune-mediated colitis, which may present with diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (1.1%), and Grade 2 (0.4%) reactions. Systemic corticosteroids were required in 69% (33/48); additional immunosuppressant therapy was required in 4.2% of patients. Colitis led to permanent discontinuation of KEYTRUDA in 0.5% (15) and withholding in 0.5% (13) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Colitis resolved in 85% of the 48 patients.
Hepatotoxicity and Immune-Mediated Hepatitis
KEYTRUDA as a Single Agent
KEYTRUDA can cause immune-mediated hepatitis. Immune-mediated hepatitis occurred in 0.7% (19/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.4%), and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 68% (13/19) of patients; additional immunosuppressant therapy was required in 11% of patients. Hepatitis led to permanent discontinuation of KEYTRUDA in 0.2% (6) and withholding in 0.3% (9) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Hepatitis resolved in 79% of the 19 patients.
KEYTRUDA with Axitinib
KEYTRUDA in combination with axitinib can cause hepatic toxicity. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider monitoring more frequently as compared to when the drugs are administered as single agents. For elevated liver enzymes, interrupt KEYTRUDA and axitinib, and consider administering corticosteroids as needed. With the combination of KEYTRUDA and axitinib, Grades 3 and 4 increased alanine aminotransferase (ALT) (20%) and increased aspartate aminotransferase (AST) (13%) were seen, which was at a higher frequency compared to KEYTRUDA alone. Fifty-nine percent of the patients with increased ALT received systemic corticosteroids. In patients with ALT 3 times upper limit of normal (ULN) (Grades 2-4, n=116), ALT resolved to Grades 0-1 in 94%. Among the 92 patients who were rechallenged with either KEYTRUDA (n=3) or axitinib (n=34) administered as a single agent or with both (n=55), recurrence of ALT 3 times ULN was observed in 1 patient receiving KEYTRUDA, 16 patients receiving axitinib, and 24 patients receiving both. All patients with a recurrence of ALT 3 ULN subsequently recovered from the event.
Immune-Mediated Endocrinopathies

Other Immune-Mediated Adverse Reactions
The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received KEYTRUDA or were reported with the use of other antiPD-1/PD-L1 treatments. Severe or fatal cases have been reported for some of these adverse reactions. Cardiac/Vascular: Myocarditis, pericarditis, vasculitis; Nervous System: Meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barr syndrome, nerve paresis, autoimmune neuropathy; Ocular: Uveitis, iritis and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss; Gastrointestinal: Pancreatitis, to include increases in serum amylase and lipase levels, gastritis, duodenitis; Musculoskeletal and Connective Tissue: Myositis/polymyositis rhabdomyolysis (and associated sequelae, including renal failure), arthritis (1.5%), polymyalgia rheumatica; Endocrine: Hypoparathyroidism; Hematologic/Immune: Hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection.
Infusion-Related Reactions
KEYTRUDA can cause severe or life-threatening infusion-related reactions, including hypersensitivity and anaphylaxis, which have been reported in 0.2% of 2799 patients receiving KEYTRUDA. Monitor for signs and symptoms of infusion-related reactions. Interrupt or slow the rate of infusion for Grade 1 or Grade 2 reactions. For Grade 3 or Grade 4 reactions, stop infusion and permanently discontinue KEYTRUDA.
Complications of Allogeneic Hematopoietic Stem Cell Transplantation (HSCT)
Fatal and other serious complications can occur in patients who receive allogeneic HSCT before or after antiPD-1/PD-L1 treatment. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute and chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between antiPD-1/PD-L1 treatment and allogeneic HSCT. Follow patients closely for evidence of these complications and intervene promptly. Consider the benefit vs risks of using antiPD-1/PD-L1 treatments prior to or after an allogeneic HSCT.
Increased Mortality in Patients With Multiple Myeloma
In trials in patients with multiple myeloma, the addition of KEYTRUDA to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of these patients with an antiPD-1/PD-L1 treatment in this combination is not recommended outside of controlled trials.
Embryofetal Toxicity
Based on its mechanism of action, KEYTRUDA can cause fetal harm when administered to a pregnant woman. Advise women of this potential risk. In females of reproductive potential, verify pregnancy status prior to initiating KEYTRUDA and advise them to use effective contraception during treatment and for 4 months after the last dose.
Adverse Reactions
In KEYNOTE-006, KEYTRUDA was discontinued due to adverse reactions in 9% of 555 patients with advanced melanoma; adverse reactions leading to permanent discontinuation in more than one patient were colitis (1.4%), autoimmune hepatitis (0.7%), allergic reaction (0.4%), polyneuropathy (0.4%), and cardiac failure (0.4%). The most common adverse reactions (20%) with KEYTRUDA were fatigue (28%), diarrhea (26%), rash (24%), and nausea (21%).
In KEYNOTE-054, KEYTRUDA was permanently discontinued due to adverse reactions in 14% of 509 patients; the most common (1%) were pneumonitis (1.4%), colitis (1.2%), and diarrhea (1%). Serious adverse reactions occurred in 25% of patients receiving KEYTRUDA. The most common adverse reaction (20%) with KEYTRUDA was diarrhea (28%).

Disease, cancer, or chemotherapy may damage or kill the bone marrow. A surgical procedure is known as bone marrow transplantation, which replaces compromised or lost bone marrow. Stem cells are collected, processed, frozen and stored in a patient's autologous transplant and then returned to the patient after intensive therapy. Stem cells are obtained from an appropriate donor in an allogeneic transplant and transplanted to the recipient to cure the disease and rebuild the immune system of the recipient.
The growing prevalence of cancer and anemia is the leading catalyst for the growth of global demand for bone marrow transplantation. In turn, global demand for bone marrow transplantation will also expand with advances in technology, enhanced health services, recent evidence of cardiac and neuronal bone marrow transplantation, expanded logistic treatment development and increased per-capita health spending. However, high treatment costs, shortage of bone marrow donors and payment instability in many countries remain a major barrier to the global demand for bone marrow transplantation.

Cell therapy and tissue engineering products for commercialization
The growing demand for bone marrow transplantation is expected to expand in the industry with several organizations involved in clinical trials for cell therapy and tissue engineering products worldwide. Many of the companies have grown from R&D to full market firms. Over the last five years, some have experienced over 30% growth. Stem cell graft is one of the fastest growing cell therapies on the market, estimated at USD 510 million by the end of 2015.
Small Bone Marrow Repayment and Billing Laps
In developed regions, the inability to pay for organ transplantation techniques in tandem with cost-effective bone marrow transplantation has contributed to the slower implementation of the bone marrow transplantation method, particularly in developing regions. Approximately 30% of the world's people consider their bone transplantation to be financially secure.
The CMS payment scheme, which returns significantly low compared to real bone marrow transplantation prices, underlines the limited scope of drugs. The amount of government interest is 47% higher than the actual cost of the operation. This adds up to nearly US$ 40,000 in transplant costs in US medical transplant hospitals.
The increase in allogeneic demand for bone marrow transplants is driven by a lower incidence of disease recurrence and a strong increase in eligible donors.
Bone marrow transplantation with allogeneic substances is currently leading the bone marrow transplantation type. Demand for allogeneic bone marrow transplantation is driven by large increases in healthy patients and a reduced risk of disease recurrence. The market will soon be dominated by autologous bone marrow transplant due to the increasing number of stem cell banks that store healthy cells in patients and the development of healthy blood cells in patients after treatment with conditioning.

The lymphoma indicator is behind a significant uptick in new cases of Hodgkin and increased survival levels for post-bone marrow transplantation.
The bone marrow transplantation industry is mainly in the lymphoma group. This consists of 2 types of Hodgkin and Non-Hodgkin lymphoma. 83,180 new cases of lymphoma were registered by the National Cancer Center (NCI) in 2018. Lymphoma progression is driven by a large increase in lymphoma patients and a higher survival rate after bone marrow transplantation. Throughout 2018, 60,300 new cases of leukemia have been reported by the National Cancer Institute, while leukemia is irregular in the development of white blood cells in the bone marrow.
Regional Stance
Europe held significant market share in 2019 in bone marrow transplantation owing to the high number of bone marrow transplants and the expansion of bone marrow registries. With strong potential for treatment, Latin America is expected to see a significant increase in the number of bone marrow transplants.

Stem cells therapy also known as regenerative medicine therapy, stem-cell therapy is the use of stem cells to prevent or treat the condition or disease. Stem cell are the special type of cells those differentiated from other type of cell into two defining characteristics including the ability to differentiate into a specialized adult cell type and perpetual self-renewal. Under the appropriate conditions in the body or a laboratory stem cells are capable to build every tissue called daughter cells in the human body; hence these cells have great potential for future therapeutic uses in tissue regeneration and repair. Among stem cell pluripotent are the type of cell that can become any cell in the adult body, and multipotent type of cell are restricted to becoming a more limited population of cells.

Covid-19 leads to shortage of bone marrow donors – GO! and Express
The SA Bone Marrow Registry (SABMR) says their ability to recruit new donors has been severely limited by the outbreak of the second Covid-19 wave.
SABMR head of donor recruitment Nadia Chalkley said they typically recruit a few hundred new donors each year from the Eastern Cape.
The shrinking pool of donors has had a material impact on our ability to match patients suffering from life threatening blood diseases with suitable donors, she said.
At any given time, there are more than 200 patients in SA that need a bone marrow transplant. The fewer donors we have, the lesser the chance of finding a match. For patients with leukemia, thalassemia and other blood disorders, a bone marrow transplant is their only hope of survival.
Chalkley said the the current odds of finding a successful match is about one in 100,000 and will only get worse as the donor pool continues to shrink.
Sadly, more than 70% of patients struggle to find a stem cell match within their own families, which means many rely on strangers for a second chance at life.
If local donors are not forthcoming, we have to look overseas for potential matches, which is costly.
She said SABMR was working hard to ensure the safety of donors and patients by allowing online registration.
We also offer at-home sampling kits, which only requires a cheek swab. These kits can be delivered and collected free of charge from anywhere in the country.
Once new donors have completed the online registration form, they will be contacted by one of our consultants to discuss the easiest way of dispatching and collecting the kits.
One of the biggest misconceptions with regards to bone marrow donation, according to Chalkley, is that it involves large needles being pushed into ones spine.
However, the most common form of donation is whats called peripheral blood stem cell collection, since the same blood-forming cells found in bone marrow are also present in circulating blood.
The process is similar to donating plasma and doesnt require surgery.
In order to register as a bone marrow donor, you must be between the ages of 16 and 45 and meet the required standards listed by the SABMR.
A full list of the criteria can be found at https://sabmr.co.za/.
Each of us have a role to play. This new year, put away frivolous resolutions and rather direct your energy into making a difference by signing up as a donor. The simple act could just make someones new years wish come true, Chalkley said.

UTV documentary tells of young Belfast woman’s lasting legacy to promote stem cell donation – The Irish News
EIMEAR Gooderham (ne Smyth) was just 25 when she died peacefully in hospital with her family at her bedside.
It was just a week after she had married Phillip Gooderham in hospital and she was buried in the wedding dress she never got to wear.
Almost two years on, her family hope a television documentary about Eimear - a make-up artist from the Coolnasilla area of west Belfast - will help create a positive and lasting legacy in her memory.
The programme, due to be broadcast on UTV and presented by journalist Sarah Clarke, features Eimear's own video diaries, which she had hoped would raise awareness of a campaign for stem cell donors that she launched before her death.
Ms Clarke said the documentary had aimed to "follow Eimear's journey, treatment and her recovery".
"She was very open about her battle and while a lot of the programme is distressing, it shows how courageous Eimear was," she said.
Eimear was diagnosed with stage two Hodgkins Lymphoma, a type of blood cancer, in September 2016.
She underwent 12 cycles of intensive chemotherapy and was given the all-clear in spring 2017.
But the disease returned and in December that year, Eimear was treated with an autologous stem cell transplant, intensive chemotherapy and her own stem cells returned afterwards to rescue her bone marrow from the effect of the treatment.
Months later she was given the good news she was in remission, but the Hodgkins Lymphoma returned again and doctors said her best chance of survival was another stem cell transplant - this time from a donor.
With neither of her siblings a match, she desperately needed to find a stem cell donor.
Eimear and her father Sean launched an appeal to raise awareness of the stem cell register, which allows donors of the correct tissue types to be matched with patients.
Their campaign saw the number of people joining the register in Northern Ireland soar.
Determined to use her own experience to help others, Eimear began filming videos on her phone for the UTV documentary.
Her desire to show her cancer battle as well as her upbeat outlook on life are reflected in the diaries, with many filmed as she underwent treatment.
Speaking ahead of the broadcast tonight, Ms Clarke said her own family's cancer battle had also inspired her to tell Eimear's story.
"In 2017, my nephew Jack was diagnosed with leukaemia, aged just 15," she said.
"I remember my brother Simon, who is a doctor, saying they may have to pursue a stem cell transplant. He knew how difficult it would be to find a match and to endure.
"Fortunately Jack didn't need it, but he had to undergo a year of intensive chemo and four years of maintenance chemo.
"It was rough and a very difficult period and thankfully he's now in remission, but it made me relate to Eimear and San's appeal."
On October 31 2018 - a year before Eimear and Phillip had planned to marry - she received her stem cell transplant.
A video extract of the days after the operation shows Eimear describe how "it's been really rough", as the donor's cells began attacking her cells - a condition known as graft versus host disease.
Despite being discharged from hospital, months later she became ill again with complications associated with the transplant - she was losing her brave battle.
Phillip tells the programme: "I wanted to tell her it was going to be ok, but I didn't want to lie to her. I wanted it to be over so she wasn't in pain".
In June 2019, the couple tied the knot and Eimear got "her final wish".
"We had had it planned, we had to cancel our wedding so it was, in the most horrific circumstances, the nicest way to end her life, by her getting her final wish," said Phillip.
Eimear died on June 27 2019.
Since then her family have continued to campaign to raise awareness of stem cell donation.
Her father Sean said they hope the programme will "highlight the need for more people in Northern Ireland to join the stem cell donor register, especially young men aged between 16 and 30".
Sarah also said while the documentary is "not exactly the one we set out to make, its still one of hope and courage".
"It was Eimears dying wish to raise awareness of stem cell donation and to help further research into the treatment to help others," she said.
"She was adamant she wanted people to sign the register and raise awareness. Her family feel the onus is now on them to continue this.
"The programme pays tribute to a courageous young woman and her family's desire to create a positive and lasting legacy in her memory."
Up Close: Eimears Wish is on UTV at 10.45pm.
What Is Leukemia: And How To Prevent It? – Technology Times Pakistan
Leukemia is the cancer of blood cells, usually white blood cells which fight and clears infections. It is also known as cancer of blood-forming tissues i.e lymphatic system and bone marrow. It is usually characterized by greatly increased numbers of abnormal white blood cells in circulating blood. It is a very serious disorder and the patient needs to change the blood regularly with normal blood from donors.
By Aysha Bibi
How does leukemia develop?
Our blood contains many different types of cells. These include red blood cells, white blood cells, and platelets. These cells are made on daily basis in the bone marrow. Leukemia happens when the body starts making white blood cells beyond its need. Immature white blood cells are released in the blood and these are non-functional. Moreover, as white blood cells increase in number, the number of red blood cells and platelets are not enough to maintain a healthy life and perform their normal functions.
Types of Leukemia
Leukemia has four main types
In the acute form of leukemia, cells multiply quickly in the bone marrow and enter the circulatory system too early but these cells are immature and non-functional. Chronic leukemia occurs when marrow produces mature cells and it progresses more slowly than other forms.
Lymphocytic leukemia is a type with an accumulation of apparently mature dysfunctional lymphocytes. Normally lymphocytes differentiate to form B-cells, T-cells, and natural killer cells which are the backbone of the immune system.
Myelogenous leukemia is a cancer of white blood cells usually granulocytes and monocytes. Either it is lymphocytic or myeloid, leukemia results in a compromised immune system, and the body cannot protect itself from different infections.
Acute lymphocytic leukemia(ALL) It is most common in children. It can spread to the central nervous system.
Acute myelogenous leukemia(AML) It is the second most common type of leukemia in children and also common in adults.
Chronic lymphocytic leukemia It is common in adults. This remains stable for many years but in some types, patients need treatment.
Chronic myelogenous leukemia(CML) Older people may are at higher risk for this type of leukemia.
Risk Factors
Some significant risk factors that can cause leukemia
Symptoms of Leukemia
Various types of leukemia can cause different symptoms. These symptoms usually not appear in the early stages, but they may include;
Diagnosis of Leukemia
CBC: with a blood test doctor looks at several different blood cells and their maturity. Immature cells may appear in the blood.
Bone marrow biopsy is done by taking bone marrow. With help of this doctor check the type and severity of leukemia.
CT scan and MRI are also done for the diagnosis of leukemia.
Treatment of Leukemia
Depending on the type of leukemia and its spreading, a doctor may look for the following options:
In a radiation treatment, high energy X-rays are used to kill leukemic cells. But normal cells are also affected.
In chemotherapy, different drugs are given to kill leukemic cells in blood and bone marrow. This may include a pill or injection in muscle or vein.
Targeted therapy is done to block the expression of some genes or proteins that are involved in the production of cancerous cells.
A Stem cell transplant involves a bone marrow transplant from a healthy donor. In this method, high-dose chemotherapy is done to destroy the leukemic cells of a patient. The healthy stems cells of donor are then injected to body.
Splenectomy is the removal of spleen and doctor may look for this option if spleen becomes fills with cancer cell and start affecting other body organs.
Preventing or reducing the risk of leukemia
Unfortunately, there is currently no cure for leukemia. Minimum exposure to pesticides and radiations may help to reduce the risk of leukemia. Leukemia can also be prevented by avoiding tobacco.
One can lower the risk of developing leukemia by following:
It is the best way to lower the risk of leukemia.
Studies have shown that overweight and obesity are also contributing factors to increasing the risk of developing leukemia.
Pollution, gasoline, car exhaust contains low levels of benzene. It is also found in offices and homes and found in paint, glue, etc. wearing a mask while using these may help you lower the risk of exposure.
Medical radiations like x-rays increase the risk of leukemia. Try to avoid unnecessary radiation exposure.
Your body and mind function at their best with a healthy diet. Proper nutrition provides energy fuel for body functioning, it also strengthens the immune system.

Full TitleA Phase 1 Multi-Dose Study of Human Placental Hematopoeitic Stem Cell Derived Natural Killer Cells (CYNK-001) in Adults with Primary or Secondary Acute Myeloid Leukemia (AML) in Morphologic Complete Remission with Minimal Residual Disease (MRD)Purpose
The purpose of this study is to find the highest dose of the investigational immunotherapy CYNK-001 that can be given safely in patients with acute myeloid leukemia (AML) that is in morphologic complete remission with minimal residual disease (MRD). Morphologic complete remission occurs when white blood cell and platelet counts are within the normal range and the amount of leukemia cells is below 5 percent in a bone marrow sample. MRD means there is still a small number of leukemia cells remaining in the bloodstream.
AML with MRD is often resistant to treatment and has a high chance of coming back. CYNK-001 is a cellular therapy made of healthy donated cells called natural killer (NK) cells. The NK cells are taken from human placenta and grown in a laboratory. There are proteins in NK cells that can kill cancer cells. CYNK-001 is given intravenously (by vein).
To be eligible for this study, patients must meet several criteria, including but not limited to the following:

National Institute for Health and Care Excellence (NICE) recommends lenalidomide as a maintenance therapy for people with newly diagnosed multiple myeloma who have undergone a stem cell transplant
Uxbridge, UK, 27th January 2021: Celgene, a Bristol Myers Squibb (BMS) company, today announces that NICE has issued a Final Appraisal Document (FAD) recommending REVLIMID (lenalidomide) as maintenance treatment after an ASCT for newly diagnosed multiple myeloma in adults.[iv] From today, approximately 1150 eligible patients in England will have immediate access to lenalidomide as a treatment option, with interim funding provided via the Cancer Drugs Fund (CDF) before transferring to baseline commissioning. Lenalidomide is the first treatment to be made available on the NHS in this setting and provides an alternative to the standard watch-and-wait approach, allowing patients to receive active treatment to keep their cancer in remission.
Graham Jackson, Professor of Clinical Haematology at Newcastle Upon Tyne NHS Foundation Trust said: Multiple myeloma is a relapsing remitting disease where the goal of treatment is to ensure long periods of remission and a good quality of life. Maintenance therapy is integral to achieving this, particularly for newly diagnosed patients who have received a stem cell transplant. Having lenalidomide within our treatment armoury on the NHS will transform the way we manage the early stages of multiple myeloma. In clinical studies maintenance therapy has been shown to almost double the initial period of remission for this group of patients, so it is fantastic to be able to offer active treatment which can help to keep the cancer at bay.
Multiple myeloma is a cancer that affects the production of plasma cells in the bone marrow and in turn impacts the bodys immune system.[v] It is characterised by a relapsing-remitting pattern, which means that the disease goes through periods where the cancer is active and needs treatment, followed by periods where it is under control.[vi] Each time the cancer relapses, the length of time spent in remission shortens.[vii] The objective of maintenance therapy is to control the cancer during the period of remission and delay relapse of the disease.[viii]
Laura Kerby, Chief Executive of Myeloma UK said: We are delighted with this outcome. Patients who receive lenalidomide maintenance after high-dose therapy and stem cell transplant have a significant increase in overall survival, so the decision to make this available through the NHS is fantastic news.
Across the UK, around 1,500 newly diagnosed multiple myeloma patients undergo an ASCT each year,1,2 and most of them will eventually relapse.[ix] This first remission is a critical period for people with multiple myeloma, as it can be an indicator of the overall survival of the disease and it has been shown that effective maintenance therapy could be essential to long-term survival.[x]
Lynelle Hoch, General Manager at Bristol Myers Squibb UK & Ireland commented: Todays announcement marks an important milestone for those living with multiple myeloma, with lenalidomide being the first maintenance treatment option to be made accessible to eligible patients in England. We are grateful for the continued collaboration with NICE, healthcare professionals and Myeloma UK to ensure patients can benefit from lenalidomide in this setting.
Following the publication of this guidance, the NHS in Wales is expected to provide funding and resources for lenalidomide in this setting within two months. The treatment is already available on the NHS in Scotland and in Northern Ireland.[xi],[xii]

If I Have Cancer, Dementia or MS, Should I Get the Covid Vaccine? – Kaiser Health News
As public demand grows for limited supplies of covid-19 vaccines, questions remain about the vaccines appropriateness for older adults with various illnesses. Among them are cancer patients receiving active treatment, dementia patients near the end of their lives and people with autoimmune conditions.
Recently, a number of readers have asked me whether older relatives with these conditions should be immunized. This is a matter for medical experts, and I solicited advice from several. All strongly suggested that people with questions contact their doctors and discuss their individual medical circumstances.
Experts advice may be helpful since states are beginning to offer vaccines to adults over age 65, 70 or 75, including those with serious underlying medical conditions. Twenty-eight states are doing so, according to the latest survey by The New York Times.
Q: My 80-year-old mother has chronic lymphocytic leukemia. For weeks, her oncologist would not tell her yes or no about the vaccine. After much pressure, he finally responded: It wont work for you, your immune system is too compromised to make antibodies. She asked if she can take the vaccine anyway, just in case it might offer a little protection, and he told her he was done discussing it with her.
First, some basics. Older adults, in general, responded extremely well to the two covid-19 vaccines that have received special authorization from the Food and Drug Administration. In large clinical trials sponsored by drugmakers Pfizer and Moderna, the vaccines achieved substantial protection against significant illness, with efficacy for older adults ranging from 87% to 94%.
But people 65 and older undergoing cancer treatment were not included in these studies. As a result, its not known what degree of protection they might derive.
Dr. Tobias Hohl, chief of the infectious diseases service at Memorial Sloan Kettering Cancer Center in New York City, suggested that three factors should influence patients decisions: Are vaccines safe, will they be effective, and what is my risk of becoming severely ill from covid-19? Regarding risk, he noted that older adults are the people most likely to become severely ill and perish from covid, accounting for about 80% of deaths to date a compelling argument for vaccination.
Regarding safety, there is no evidence at this time that cancer patients are more likely to experience side effects from the Pfizer-BioNTech and Moderna vaccines than other people. Generally, we are confident that these vaccines are safe for [cancer] patients, including older patients, said Dr. Armin Shahrokni, a Memorial Sloan Kettering geriatrician and oncologist.
The exception, which applies to everyone, not just cancer patients: people who are allergic to covid-19 vaccine components or who experience severe allergic responses after getting a first shot shouldnt get covid-19 vaccines.
Efficacy is a consideration for patients whose underlying cancer or treatment suppresses their immune systems. Notably, patients with blood and lymph node cancers may experience a blunted response to vaccines, along with patients undergoing chemotherapy or radiation therapy.
Even in this case, we have every reason to believe that if their immune system is functioning at all, they will respond to the vaccine to some extent, and thats likely to be beneficial, said Dr. William Dale, chair of supportive care medicine and director of the Center for Cancer Aging Research at City of Hope, a comprehensive cancer center in Los Angeles County.
Balancing the timing of cancer treatment and immunization may be a consideration in some cases. For those with serious disease who need therapy as quickly as possible, we should not delay [cancer] treatment because we want to preserve immune function and vaccinate them against covid, said Hohl of Memorial Sloan Kettering.
One approach might be trying to time covid vaccination in between cycles of chemotherapy, if possible, said Dr. Catherine Liu, a professor in the vaccine and infectious disease division at Fred Hutchinson Cancer Research Center in Seattle.
In new guidelines published late last week, the National Comprehensive Cancer Network, an alliance of cancer centers, urged that patients undergoing active treatment be prioritized for vaccines as soon as possible. A notable exception: Patients whove received stem cell transplants or bone marrow transplants should wait at least three months before getting vaccines, the group recommended.
The American Cancer Societys chief medical and scientific officer, Dr. William Cance, said his organization is strongly in favor of cancer patients and cancer survivors getting vaccinated, particularly older adults. Given vaccine shortages, he also recommended that cancer patients who contract covid-19 get antibody therapies as soon as possible, if their oncologists believe theyre good candidates. These infusion therapies, from Eli Lilly and Co. and Regeneron Pharmaceuticals, rely on synthetic immune cells to help fight infections.
Q: Should my 97-year-old mom, in a nursing home with dementia, even get the covid vaccine?
The federal government and all 50 states recommend covid vaccines for long-term care residents, most of whom have Alzheimers disease or other types of cognitive impairment. This is an effort to stem the tide of covid-related illness and death that has swept through nursing homes and assisted living facilities 37% of all covid deaths as of mid-January.
The Alzheimers Association also strongly encourages immunization against covid-19, both for people [with dementia] living in long-term care and those living in the community, said Beth Kallmyer, vice president of care and support.
What I think this question is trying to ask is Will my loved one live long enough to see the benefit of being vaccinated? said Dr. Joshua Uy, medical director at a Philadelphia nursing home and geriatric fellowship director at the University of Pennsylvanias Perelman School of Medicine.
Potential benefits include not becoming ill or dying from covid-19, having visits from family or friends, engaging with other residents and taking part in activities, Uy suggested. (This is a partial list.) Since these benefits could start accruing a few weeks after residents in a facility are fully immunized, I would recommend the vaccine for a 97-year-old with significant dementia, Uy said.
Minimizing suffering is a key consideration, said Dr. Michael Rafii, associate professor of clinical neurology at the University of Southern Californias Keck School of Medicine. Even if a person has end-stage dementia, you want to do anything you can to reduce the risk of suffering. And this vaccine provides individuals with a good deal of protection from suffering severe covid, he said.
My advice is that everyone should get vaccinated, regardless of what stage of dementia theyre in, Rafii said. That includes dementia patients at the end of their lives in hospice care, he noted.
If possible, a loved one should be at hand for reassurance since being approached by someone wearing a mask and carrying a needle can evoke anxiety in dementia patients. Have the person administering the vaccine explain who they are, what theyre doing and why theyre wearing a mask in clear, simple language, Rafii suggested.
Q: Im 80 and I have Type 2 diabetes and an autoimmune disease. Should I get the vaccine?
There are two parts to this question. The first has to do with comorbidities having more than one medical condition. Should older adults with comorbidities get covid vaccines?
Absolutely, because theyre at higher risk of becoming seriously ill from covid, said Dr. Abinash Virk, an infectious diseases specialist and co-chair of the Mayo Clinics covid-19 vaccine rollout.
Pfizers and Modernas studies specifically looked at people who were older and had comorbidities, and they showed that vaccine response was similar to [that of] people who were younger, she noted.
The second part has to do with autoimmune illnesses such as lupus or rheumatoid arthritis, which also put people at higher risk. The concern here is that a vaccine might trigger inflammatory responses that could exacerbate these conditions.
Philippa Marrack, chair of the department of immunology and genomic medicine at National Jewish Health in Denver, said theres no scientifically rigorous data on how patients with autoimmune conditions respond to the Pfizer and Moderna vaccines.
So far, reasons for concern havent surfaced. More than 100,000 people have gotten these vaccines now, including some who probably had autoimmune disease, and theres been no systematic reporting of problems, Marrack said. If patients with autoimmune disorders are really worried, they should talk with their physicians about delaying immunization until other covid vaccines with different formulations become available, she suggested.
Last week, the National Multiple Sclerosis Society recommended that most patients with multiple sclerosis another serious autoimmune condition get the Pfizer or Moderna covid vaccines.
The vaccines are not likely to trigger an MS relapse or to worsen your chronic MS symptoms. The risk of getting COVID-19 far outweighs any risk of having an MS relapse from the vaccine, it said in a statement.
