AIM: To evaluate the natural history of human cytomegalovirus (HCMV) infection in a series of 28 ulcerative colitis patients in whom the search for HCMV was positive. METHODS: A series of 85 patients with moderate-severe ulcerative colitis flare-up were evaluated for a HCMV search by performing a haematoxylin and eosin stain, immunohistochemical assay and nested polymerase chain reaction on rectal biopsies. Among 85 screened patients (19 of whom were steroid resistant/dependant), 28 were positive for HCMV; after remission the patients were followed up clinically and histologically. RESULTS: Among the 22 patients with complete follow-p, in 8 (36%) patients HCMV-DNA persisted in the intestinal specimens. Among the HCMV positive patients, 4 (50%) experienced at least one moderate-severe flare-up of colitis without evidence of peripheral HCMV. Among the 14 HCMV negative patients, 3 with pouches developed pouchitis and 5 out of 11 (45%) experienced a colitis flare-up. CONCLUSION: Our preliminary results suggest that HCMV may remain in the colon after an acute colitis flare-up despite remission; it seems that the virus is not responsible for the disease relapse.
