Methods: We have observed six patients with hemorrhagic colitis associated with the use of amoxicillin or penicillin derivatives. Clinical manifestation, laboratory tests, colonoscopy examination, treatment and prognosis were analysed. Results: All patients had been given amoxicillin or penicillin derivatives, symptoms of colitis started within 1 week; The onset was sudden, with hematochezia and abdominal cramps or discomfort; Laboratory test manifested leukocytosis (67%); The mucosal change which included diffuse mucosal hemorrhage and erosion was mostly located at the right colon by colonoscopy; Histopathologic examination showed chronic inflammatory of colonic mucosa and redcell infiltrating into the interstitial; Stopped oral antibiotic, support treatment and glucocorticoid were given for short times by transfusion; The patients recovered quickly without any complications.
