About

CytoMegaloVirus (CMV) infection impairs evolution of Ulcerative Colitis (UC) leading to more severe and resistant to immunosuppressive therapies flare-up. CytoMegaloVirus (CMV) reactivation is assessed by the quantification of the CytoMegaloVirus (CMV) DeoxyriboNucleic Acid (DNA) load by real-time PCR (qPCR) in colonic biopsies; this assay is invasive and costly. The QuantiFERON-CytoMegaloVirus (QF-CMV) assay measures the immune response against CytoMegaloVirus (CMV) in a blood specimen.

Full description

This study aim to evaluate the performances of this new assay to predict the risk of CytoMegaloVirus (CMV) reactivation in the colon of UC patients. A new algorithm for the care of Ulcerative Colitis (UC) patients that could be used in all centers, even those without molecular biology lab, could be proposed: in case of a positive QuantiFERON-CytoMegaloVirus (QF-CMV) assay, the immune response protects the patient against Cytomegalovirus (CMV) reactivation and intensification of immunosuppressive therapies should be proposed; at the opposite, a negative QuantiFERON-CytoMegaloVirus (QF-CMV) assay will invite to biopsy in order to detect CytoMegaloVirus (CMV) replication and to treat with ganciclovir when appropriate. This algorithm will preserve invasive biopsies in absence of CytoMegaloVirus (CMV) tissue reactivation.
