    Abstract:
    A 25-year-old man presented with abdominal pain and bloody diarrhea. Colonoscopy showed hemorrhagic proctocolitis with superficial erosions. Histology was consistent with the diagnosis of ulcerative colitis and biopsy cultures were negative. Despite treatment with prednisolone (40 mg/day), his clinical condition deteriorated and he was referred to our institution. On repeated questioning, the patient reported self-medication with diclofenac (200 mg/day) for 6 weeks to treat tendinitis prior to the beginning of digestive symptoms. Rectosigmoidoscopy confirmed bleeding colitis and repeated biopsy cultures showed Klebsiella oxytoca. Corticosteroids were stopped and ofloxacin (400 mg/day) was prescribed for 14 days. Diarrhea quickly resolved. Colonoscopy 8 weeks later showed only patchy erythematous mucosa without bleeding or erosions. Two years later, the patient remains asymptomatic with normal total colonoscopy. The definitive diagnosis was de novo NSAID-induced colitis subsequently complicated by Klebsiella oxytoca infection.
