Real-world effectiveness of caplacizumab vs the standard of care in immune thrombotic thrombocytopenic purpura.

Immune thrombotic thrombocytopenic purpura (iTTP) is a thrombotic microangiopathy caused by anti-ADAMTS13 antibodies. Caplacizumab is approved for adults with an acute episode of iTTP in conjunction with plasma exchange (PEX) and immunosuppression. The objective of this study was to analyze and compare the safety and efficacy of caplacizumab vs the standard of care and assess the effect of the concomitant use of rituximab.

Influence of glutathione S-transferase T1 donor/recipient mismatch and anti-GSTT1 antibodies in hepatic graft-versus-host-disease.

B cell responses to minor histocompatibility antigens (mHags) have not been extensively studied after allogeneic hematopoietic stem cell transplantation (HSCT). Glutathione S-transferase T1 (GSTT1) is a drug metabolizing enzyme encoded by a single gene that is highly expressed in liver and kidney. Anti-GSTT1 antibodies have been described in the context of antibody-mediated rejection in kidney and liver transplantation, due to a mismatch between donor and recipient.
