title: The complement system in chronic lymphocytic leukemia: a possible role in autoimmune manifestations.
abstract: We describe the complement system of three CLL patients who developed autoimmune complications in the course of their disease. The complement profile was pathological in both CLL patients with active autoimmune diseases, while it showed no deficiency in the patient with quiescent autoimmunity. The complement profile could be an early marker for development of autoimmunity in CLL patients
