Which is NOT a cause of autoimmune hemolytic anemia?

Autoimmune hemolytic anemia (AIHA) occurs when the immune system mistakenly targets and destroys red blood cells, leading to anemia. Various conditions and factors can be associated with this disorder.

Lymphoproliferative disorders are closely linked with AIHA due to the abnormal proliferation of lymphocytes, which can produce autoantibodies against red blood cells. This connection makes them a recognized cause of AIHA.

Ulcerative colitis, an inflammatory bowel disease, also has associations with various autoimmune phenomena, including the development of AIHA. The inflammatory processes involved in ulcerative colitis can trigger dysfunctional immune responses resulting in hemolysis.

Certain medications, including penicillin (PCN) and quinine, are known triggers for drug-induced AIHA. These drugs can provoke an immune response that leads to the production of antibodies against red blood cells.

Chronic alcohol use, while it may lead to other forms of hematologic disorders or exacerbate pre-existing liver disease, is not a recognized direct cause of autoimmune hemolytic anemia. Unlike the other listed factors, alcohol use is not generally associated with the production of autoantibodies or the pathophysiology of AIHA. Therefore, it does not fit into the category as a
