It is an autoimmune disease mediated by T lymphocytes or by an IgG antibody against erythroid precursors in the bone marrow or both. In adults, the disease is usually idiopathic. However, cases have been seen in association with SLE, chronic lymphocytic leukemia (CLL), lymphomas, or thymoma. Some medications (phenytoin, chloramphenicol) may cause RBC aplasia. Rarely, anti-erythropoietin antibodies cause pure RBC aplasia in patients who are treated with recombinant erythropoietin. Transient episodes of RBC 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.
