Hematologic aspects of systemic lupus erythematosus. Current concepts.

Abstract

Anemia occurs in more than one half of patients with systemic lupus erythematosus and is usually attributed to "chronic disease." Approximately 10% of patients with a positive Coombs' test manifest clinically significant hemolysis. Leukopenia affects both granulocytic and lymphocytic lines and may be caused by autoantibodies. Nevertheless, enhancement of B lymphocyte function occurs in active disease, perhaps due to a loss of regulatory T cells. Most patients have increased production and increased peripheral destruction of thrombocytes, with a normal circulation platelet count. Thrombocytopenia is usually caused by increased destruction. Qualitative abnormalities of platelet aggregation also occur. Circulation anticoagulants are not rare; however, spontaneous bleeding is uncommon. The anticoagulants, immunoglobulins directed against clotting factors, assume importance for invasive procedures. Most clinically significant hematopoietic abnormalities can be suppressed by corticosteroids; however, splenectomy, or immunosuppressive agents, or both, may be indicated for patients who respond inadequately to corticosteroids.
