Review Meta Analysis
COVID-19 vaccine-associated immune thrombosis and thrombocytopenia (VITT): Diagnostic and therapeutic recommendations for a new syndrome.
Very rare cases of thrombosis associated with thrombocytopenia have occurred following the vaccination with AstraZeneca COVID-19 vaccine. The aim of this concise review is to summarize the current knowledge on the epidemiologic and pathogenic mechanisms of this syndrome named vaccine-associated immune thrombosis and thrombocytopenia (VITT). A practical patient management section will also be dealt with using information available from national and international scientific societies as well as expert panels. ⋯ Overall, 40 VITT cases have been reported. Continuous pharmacovigilance monitoring is needed to collect more data on the real incidence and the pathogenesis of VITT syndrome. Such information will also help us to optimize the management this rare but often clinically severe thrombotic condition associated with COVID-19 vaccination.

Review Meta Analysis
B cell maturation antigen-specific chimeric antigen receptor T cells for relapsed or refractory multiple myeloma: A meta-analysis.
Chimeric antigen receptor (CAR) T cells targeting B cell maturation antigen (BCMA) have shown impressive results in clinical studies for relapsed/refractory multiple myeloma (RRMM). We performed a systematic literature review to summarize the current body of evidence on the role of anti-BCMA CAR T cells for RRMM. ⋯ Anti-BCMA CAR T cells showed high response rates, even in patients with present extramedullary disease, while relapse occurred in half of the patients who achieved a response. Larger studies with longer follow-up especially evaluating the association of response and survival are needed.

Thrombopoietin receptor agonists (TPOra) are the only treatments for immune thrombocytopenia (ITP) for which evidence of efficacy and safety from randomized, placebo-controlled trials is available. We sought to determine the long-term tolerability of the TPOra romiplostim, with a particular focus on thrombosis, bleeding, bone marrow (BM) reticulin, neoplasms/haematological malignancies and fatal events. ⋯ Romiplostim is the TPOra for which the longest duration of safety data is available. Our data demonstrate that long-term romiplostim treatment is well tolerated, with no new safety signals, even in patients treated for up to 5 yr.
