Abstract
BACKGROUND The precise role of cytomegalovirus (CMV) in ulcerative colitis (UC) remains disputed. We evaluated the association of CMV-specific host immune responses and systemic or local viral replication with responses to systemic steroids in patients with moderate to severe UC. METHODS Patients who were hospitalized for moderate to severe UC between April 2015 and June 2016 were enrolled. At baseline, all enrolled patients underwent CMV-specific enzyme-linked immunospot assays, quantitative polymerase chain reaction (qPCR) analysis of blood and colonic tissue for CMV viral load, histopathological testing for CMV in colonic tissue by hematoxylin and eosin staining, and immunohistochemical (IHC) analysis. Clinical responses to steroid therapy based on the Oxford index were assessed on day 3. RESULTS Of the 80 patients evaluated, 28 (35.0%) had poor responses to steroid therapy on day 3 of intensive treatment. The presence of inclusion bodies (32.1%) and high-grade (≥3) positivity on IHC (50.0%), as well as colonic (mean 1440.4 copies/mg) and blood (mean, 3692.6 copies/mL) CMV viral load, were higher in steroid-refractory UC patients than the control group (13.5%, 1.9%, mean 429.2 copies/mg, and mean 231.2 copies/mL, respectively; P = .046, .009, .017, and .002, respectively). However, CMV-specific T-cell responses were not associated with steroid-refractory UC. Multivariate analysis revealed that a higher Mayo score (odds ratio [OR], 2.00; P = .002) and higher blood CMV viral load via qPCR analysis (OR, 3.58; P = .044) were independent risk factors for steroid-refractory UC. CONCLUSIONS In patients with moderate to severe UC, higher Mayo score and blood CMV expression determined by qPCR are independently associated with steroid refractoriness.
