Abstract

INTRODUCTION: Because of the variety of definitions used to describe moderate aplastic anemia (MAA), we review our institutional experience period with patients who met a proposed set of criteria for this disorder. On an exploratory basis, we sought to evaluate the influence of treatment with immunosuppressive therapy (IST) versus observation on long-term outcomes. MATERIALS AND METHODS: Records from 1999 to 2010 were screened for patients who met the criteria for MAA: (1) bone marrow cellularity of 20% to 50%; (2) cytopenias in at least 1 cell line (absolute neutrophil count<1000/μL, hemoglobin<9 g/dL, platelet count<100,000/μL); (3) mean corpuscular volume ≥90; (4) persistence >6 months; and (5) negative Fanconi studies. Data were collected for patient/disease characteristics, treatments, and outcomes. RESULTS: Eight patients met the criteria for MAA. Three of 8 patients received IST. Of 3 patients who received IST, complete response was observed in 2 and transfusion independence in 1, as compared with 2 of 5 and 3 of 5 in the group who were observed without IST. Median duration of follow-up was 48 months. DISCUSSION: As several patients spontaneously resolved, and none developed severe aplastic anemia, acute myelogenous leukemia, or myelodysplastic syndrome, the criteria used here may identify a group of children with favorable prognosis who can be managed supportively.
