RA patients taking glucocorticoids or B-cell therapies may have worse COVID-19 vaccine response

New research presented this week at ACR Convergence, the American College of Rheumatology's annual meeting, shows that people with chronic inflammatory diseases, such as rheumatoid arthritis (RA), who take immunosuppressive therapy appear to have an impaired immunity response to SARS-CoV-2, the coronavirus that causes COVID-19, vaccines. Patients currently on glucocorticoids or B-cell depleting therapy appear to have an even more severely impeded vaccine response.

Immunocompromised patients using rituximab could benefit from third COVID-19 booster vaccine

New research presented this week at ACR Convergence, the American College of Rheumatology's annual meeting, shows immunocompromised patients using rituximab (a drug used to treat diseases like rheumatoid arthritis) were able to produce antibodies against COVID-19 (seroconvert) after receiving a third COVID-19 vaccine dose, even if there was no development of the antibody after the first two doses of the vaccine.

CAR-T cell treatment's efficacy in hematological malignancies predicted by epigenetics

One in five cancers affects blood cells and lymph nodes, causing leukemias and lymphomas, respectively. Although their treatment with drugs has led to a great advance in their cure, there are cases where there is no clinical response or resistance to them is generated.
