Implication

Case series demonstrates circulating anti-erythroid factors and steroid responsiveness in pure red cell aplasia, highlighting an underlying immunological mechanism across diverse etiologies.

Key Points

To examine the presence of circulating cytotoxic factors targeting erythroid precursors and assess immunosuppressive treatment outcomes across distinct presentations of pure red cell aplasia.
Evaluated three clinical cases of pure red cell aplasia arising idiopathically, secondary to histiocytic lymphoma, or associated with diphenylhydantoin therapy (N=3).
Performed in vitro serum assays to detect cytotoxic or inhibitory factors directed against erythroid precursor cells.
Administered corticosteroid therapy and drug withdrawal to evaluate clinical remission.
In vitro assays demonstrated circulating toxic factors against erythroid precursors in the lymphoma-associated and diphenylhydantoin-associated cases, but not in the idiopathic case.
Corticosteroid therapy induced complete hematologic remission in both the idiopathic and lymphoma-associated cases.
Cessation of diphenylhydantoin combined with corticosteroid administration resulted in rapid clinical remission in the drug-induced case.
