The last episode was treated with cyclosporin\u2010A (CyA) and prednisone. After the patient was on the therapy for 2 weeks, erythropoietic recovery was observed and with continued therapy the hematocrit (Hct) became normal. The PRCA remission was associated with a fall in the blood lymphocyte count, and a reduction in the spleen and lymph node size and bone marrow lymphocyte density. At diagnosis of PRCA the blood T\u2010cells bearing IgG Fc receptors (T gamma cells) were increased, and the marrow contained very few or no late\u2010stage erythroid progenitors. After remission of PRCA the T gamma cell fraction decreased, and the marrow erythroid progenitor's number became normal. We speculate that therapy with CyA and prednisone inhibited the production of interleukins\u20101 and \u20102 from monocytes and T\u2010cells, respectively, and was responsible for the reduction of the T gamma cell fraction and B\u2010cell leukemic mass in this patient. Further, we believe that normalization of T gamma cells in association with the therapy was responsible for the PRCA remission.<\/jats:p>","DOI":"10.1002\/ajh.2830260209","type":"journal-article","created":{"date-parts":[[2007,2,21]],"date-time":"2007-02-21T11:03:33Z","timestamp":1172055813000},"page":"179-189","source":"Crossref","is-referenced-by-count":21,"title":["Cyclosporin\u2010a for the treatment of pure red cell aplasia in a patient with chronic lymphocytic leukemia"],"prefix":"10.1002","volume":"26","author":[{"given":"G.","family":"Chikkappa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Pasquale","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.
