Department of Internal Medicine, Kawasaki Social Insurance Hospital, Japan.

A 70-year-old Japanese man with chronic kidney disease under treatment with oral prednisolone for organizing pneumonia developed pulmonary aspergilloma. The patient was started on micafungin (MCFG), with no addition of any other new drug. About 5 weeks later, aggravation of his normocytic anemia associated with a low reticulocyte count was observed. Bone marrow puncture and biopsy revealed intense hypoplasia of the erythroblasts. As there was no evidence of malignancy, human parvovirus B19 infection, autoimmune diseases or hemorrhage, the patient was diagnosed as having acquired pure red cell aplasia (PRCA). The anemia improved along with an increase of the reticulocyte count to the normal level within 12 weeks of discontinuation of the MCFG therapy. The patient showed no evidence subsequently of any recurrence of the normocytic normochromic anemia or relapse of the PRCA. This is the first reported case of PRCA associated with MCFG.

UI MeSH Term Description Entries
D007166 Immunosuppressive Agents Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.

D001853 Bone Marrow The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

D000368 Aged A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available. Elderly
D000935 Antifungal Agents Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues.

D054714 Echinocandins Cyclic hexapeptides of proline-ornithine-threonine-proline-threonine-serine. The cyclization with a single non-peptide bond can lead them to be incorrectly called DEPSIPEPTIDES, but the echinocandins lack ester links. Antifungal activity is via inhibition of 1,3-beta-glucan synthase production of BETA-GLUCANS. Aculeacin,Echinocandin,Pneumocandin,Aculeacins,Mulundocandins,Pneumocandins
