The development of autoantibodies after allogeneic stem cell transplantation is related with chronic graft-vs-host disease and immune recovery.

Objective: Chronic graft-vs-host disease (GVHD) has certain similarities with autoimmune diseases and is associated with the development of various autoantibodies in some patients. In this study, we analyzed the occurrence of autoantibodies in 63 patients surviving longer than 3 months after an allogeneic haematopoietic stem cell transplantation (HSCT), with the aim of detecting a possible association between occurrence of autoantibodies and development of chronic GVHD and immune recovery after HSCT.

Patients And Methods: The patients were screened every 3 months for the occurrence of the following autoantibodies: anti-nuclear (ANA), anti-mitochondrial (AMA), anti-smooth muscle (ASMA), anti-cardiolipin (ACLA), anti-liver-kidney microsomal (LKM), anti-DNA, anti-neutrophil cytoplasmatic (ANCA), and anti-thyroid antibodies.
