چکیده
BACKGROUND AND AIM Cytomegalovirus (CMV) exacerbates ulcerative colitis (UC) refractory to immunosuppressive therapies. The conditions under which CMV reactivation occurs in patients with UC, however, is unclear. In addition, the diagnostic and treatment strategies for UC positive for CMV have not been established. Granulocyte and monocyte adsorptive apheresis (GMAA) is natural biological therapy for UC in which the granulocytes/macrophages producing inflammatory cytokines are removed. We investigated the rate of colonic CMV reactivation and the efficacy of GMAA in active UC patients positive for CMV without concomitant corticosteroid (CS) therapy. METHODS Fifty-one active UC patients without concomitant CS therapy were enrolled. Colonic CMV reactivation was examined by real-time polymerase chain reaction (PCR) using biopsy specimen and/or histological examination. All patients were treated with intensive GMAA (twice per week). Rates of clinical remission and mucosal healing were compared between UC patients positive and negative for CMV. RESULTS Of 51 patients, 15 (29.4%) were diagnosed as CMV positive. The clinical remission rates following intensive GMAA did not differ between UC patients positive and negative for CMV (73.3% vs 69.4%, p=0.781). Proportion of patients achieving mucosal healing was also similar between these two groups. CMV-DNA became negative in all UC patients positive for CMV who achieved clinical remission 1 week after completion of intensive GMAA. CONCLUSIONS Intestinal inflammation might trigger CMV reactivation in a subpopulation of active UC patients without CS treatment. GMAA could be a promising option for active UC positive for CMV.

BACKGROUND Fecal lactoferrin has been introduced as a useful tool for the diagnosis and monitoring of inflammatory bowel disease (IBD). The aim of this study was to assess if fecal lactoferrin can be employed to predict or estimate the effect of granulocyte and monocyte adsorptive apheresis (GMA) in ulcerative colitis (UC). METHODS This was a prospective study involving 21 patients with UC. P...
متن کاملAdsorptive Granulocyte and Monocyte Apheresis in the Treatment of Ulcerative Colitis: The First Multicenter Study in China
Background/Aims Patients with active ulcerative colitis (UC) have elevated levels of activated myeloid-derived leukocytes as a source of inflammatory cytokines. The selective depletion of these leukocytes by adsorptive granulocyte/monocyte apheresis (GMA) with an Adacolumn should alleviate inflammation, promote remission and enhance drug efficacy. However, studies have reported contrasting effi...
