Abstract
Introduction
Clostridium difficile infection (CDI) has been reported to be a cause of flare-ups in patients with inflammatory bowel disease (IBD). Cytomegalovirus (CMV) infection can cause severe disease and complications in immunocompromised patients in consequence of disease or therapy.
Aim
Our aim was to describe the prevalence and clinical outcomes of CDI with concomitant CMV infection in IBD patients hospitalized for flare-ups in association with the disease itself and medication used.
Methods
We prospectively identified consecutive patients referred for CDI management during 2015-2017. Stool samples were tested for Clostridium difficile toxin A and/or B and Glutamate Dehydrogenase in patients with clinical symptoms. CDI patients with IBD history were tested for anti-CMV IgG and IgM antibodies by chemiluminescent microparticle immunoassay and underwent histological analysis for CMV on colon biopsies. Data were collected for demographic characteristics, treatment and outcome.
Results
125 patients with CDI were enrolled. Among these patients, 14 (11.2%) were diagnosed with IBD. The mean patient age of IBD patients was 52.5±15.4 years at diagnosis of CDI, 85.7% had UC, 14.3% CD, while the age of patients was shared. Eleven of the total of 14 patients (78.6%) tested positive for anti-CMV IgG. Of these, 3 patients (21.4%) exhibited high CMV IgG avidity, without detectable anti-CMV IgM and biopsy-proven CMV colitis. Of the 14 IBD patients with CDI, 8 patients (57.1%) were receiving anti-tumor necrosis factor (anti-TNF) therapy (21.4 % infliximab or golimumab, 7.1% vedolizumab or adalimumab) and 43.5% of patients were being treated with systemic corticosteroids. Four UC patients (28.6%) on steroids of the 14 CDI patients underwent a colectomy whereas none of the not on steroids patients underwent colectomy (p=0.25). Among them, 1 patient (7.1%) had recurrent CDI after 5 months from the first episode of CDI.These patients were treated with vancomycin, metronidazole and fidaxomicin. The mean age of patients that had a colectomy 65.5±9.32 (n=4) was higher than the mean age of those 47.30±14.49 (n=10) who improved (UMann-Whitney=6. p=0.04).
Conclusions
Immunosuppressive medications and older age are associated with increased risk of CDI and poor outcome. Although, CMV is a rare colonic pathogen in the immunocompetent patient, it should be included and screened when exacerbation of IBD occurs in patients receiving any type of immunosuppressive therapy.
