Rare Clinical Association between Infection and Ischemic Colitis: Case Report and Literature Review.

Gut microbiota plays an important role in the wellbeing of the host through different interactions between microflora constituents. In certain instances, may pullulate, causing infection with associated colitis that may vary in terms of severity from mild disease to severe colitis, with increased associated mortality due to its complications. However, there are few literature data regarding the association between and ischemic colitis. We report the case of a 30-year-old male patient, overweight, with impending dehydration, who presented with hematochezia and colicky abdominal pain, with positive fecal tests for the detection of infection and endoscopic appearance suggesting ischemic colitis in the sigmoid and left colon, confirmed by computed tomography and histology. The patient was treated with oral Vancomycin, with resolution of symptoms, and was reevaluated through colonoscopy eight weeks after discharge, with endoscopic mucosal normalization and histological scarring process on biopsy samples. We report one of the few cases in the literature of ischemic colitis associated with infection, with resolution of clinical, endoscopic, and histologic changes after specific treatment with oral Vancomycin suggesting a possible association between the two diseases. We also review the existing literature data regarding this comorbid association.
