Paroxysmal nocturnal hemoglobinuria (PNH) is defined by acquired intravascular hemolytic anemia, thrombosis and bone marrow failure with pancytopenia. Systemic lupus erythematosus (SLE) also appears as an autoimmune disease. The coexistence of both is rarely reported. Here we report the case of a 30-year-old female presenting with pancytopenia and diagnosed as SLE, who also had a PNH clone. Bone marrow biopsy did not support hypoplastic anemia. The patient was then followed up with the consideration of the existence of a PNH clone with SLE. She was treated by the rheumatology department and complete blood count improved under immunosuppressive treatment. The coexistence of CD59–CD55 deficiency with autoimmune diseases has been reported. It is an important example in terms of receiving clinical response with SLE-specific treatment.

We studied a patient with a rare complication of amegakaryocytic thrombocytopenia (AMT) associated with systemic lupus erythematosus (SLE). To investigate the underlying pathogenesis of AMT, the effects of peripheral blood T cells and serum on human megakaryocyte progenitor cells were studied using in vitro coculture techniques. Mononuclear bone marrow cells (2 X 10(5) from normal donors produced 33.6 +/- 8.8 (n = 10) colony-forming unit-megakaryocytes (CFU-M) in our plasma clot system. When 2 X 10(5) of the patient's T cells were added to the culture system, the number of CFU-M decreased to only 3.5 +/- 0.6/2 X 10(5) bone marrow cells. No evidence of inhibitory effects was found by the addition of the patient's serum and complement to the culture system. The T cells stored at -80 degrees C on admission were also capable of suppressing autologous CFU-M after recovery from AMT. These results indicate that in vitro suppression of CFU-M from allogenic and autologous bone marrow cells by this patient's T cells provides an explanation for the pathogenesis of AMT associated with SLE.
