It is an autoimmune disease mediated by T lymphocytes and/or by an IgG antibody against erythroid precursors in the bone marrow. In adults, the disease is usually idiopathic. However, cases have been seen in association with systemic lupus erythematosus, chronic lymphocytic leukemia (CLL), lymphomas, or thymoma. Some medications (phenytoin, chloramphenicol) may cause red cell aplasia. Rarely, anti-erythropoietin antibodies cause pure red cell aplasia in patients who are treated with recombinant erythropoietin. Transient episodes of red cell aplasia are probably common in response to viral infections, especially parvovirus infections. However, these acute episodes will go unrecognized unless the patient has a chronic hemolytic disorder or a chronic immunocompromised state, in which case the hematocrit may fall precipitously.
