[Autoimmune hemolytic anemia during treatment with cyclosporin after liver transplantation]. / Anémie hémolytique auto-immune au cours d'un traitement par la ciclosporine après transplantation hépatique.

Hemolytic anemia was observed in a 36 year-old liver transplant patient. The immunosuppressive regimen included cyclosporine A and prednisolone. Hemolysis appeared a few days after amoxicillin treatment. The presence of anti-D allo-antibodies, auto-antibodies active against erythrocytes, and an immuno-allergic phenomenon against erythrocytic membrane coated by cyclosporine was demonstrated. Increase of daily dose of prednisolone without modification of cyclosporine doses was followed by the disappearance of allo- and auto-sensitization. The role of amoxicillin in promoting these hemolytic phenomenons may be suggested.
