The patient was originally admitted to the medical service for the management of a rapidly progressing 10\u2005cm ulcer on her left lower extremity. Prior to admission, the patient had been on several immunosuppressive agents for the treatment of microscopic polyangiitis, including prednisone, azathioprine, cyclophosphamide and rituximab. Her hospital course was notable for pancytopenia and after a very thorough diagnostic work-up, the aetiology was found to be secondary to CMV reactivation. This was confirmed by blood analysis that revealed a highly elevated CMV level at 899\u2005100\u2005copies\/mL by quantitative PCR. The patient was promptly treated with intravenous ganciclovir for a total course of 14\u2005days before transitioning to an oral regimen. She had a pronounced response to the anti-CMV therapy with complete recovery of her white cell count, haemoglobin and platelet count to baseline.<\/jats:p>","DOI":"10.1136\/bcr-2013-201857","type":"journal-article","created":{"date-parts":[[2014,1,13]],"date-time":"2014-01-13T05:49:19Z","timestamp":1389592159000},"page":"bcr2013201857","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Pancytopenia secondary to cytomegalovirus reactivation"],"prefix":"10.1136","volume":"2014","author":[{"given":"Justin Ruey","family":"Tse","sequence":"first","affiliation":[{"name":"David Geffen School of Medicine, University of California, Los Angeles, Los Angeles, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gan Xon","family":"Ng","sequence":"additional","affiliation":[{"name":"David Geffen School of Medicine, University of California, Los Angeles, Los Angeles, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2014,1,13]]},"reference":[{"key":"2025082803165798000_2014.jan13_1.bcr2013201857.1","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/ken231"},{"key":"2025082803165798000_2014.jan13_1.bcr2013201857.2","doi-asserted-by":"crossref","first-page":"2190","DOI":"10.1111\/trf.12390","article-title":"Cytomegalovirus (CMV) seroprevalence in Japanese blood donors and high detection frequency of CMV DNA in elderly donors","volume":"53","author":"Furui","year":"2013","journal-title":"Transfusion"},{"key":"2025082803165798000_2014.jan13_1.bcr2013201857.3","doi-asserted-by":"crossref","unstructured":"Ho M .
