Necrotizing ileitis caused by cytomegalovirus in patient with systemic lupus erythematosus: case report.
We report a systemic lupus erythematosus (SLE) patient with necrotizing ileitis diagnosed at a tertially care centre in Thailand. The patient was surgically explored because peritonitis was suspected and segmental gangrenous and perforation of the terminal iliem were found. The pathological finding was necrotizing ileitis with appearance of cytomegalic intranuclear inclusion body. The presence of cytomegalovirus (CMV) infection in tissue was confirmed by CMV-DNA detection using polymerase chain reaction and ELISA probe hybridization method. The hemoculture and peritoneal fluid culture results revealed no pathogenic organisms. Postoperatively, the clinical course of the patient deteriorated and she developed hypotension. Vasopressive drugs were administered without clinical improvement. She expired on day 5 postoperation. Regarding CMV infection, the organism involves the small bowel in only 4.3 per cent of all CMV infections of the gastrointestinal tract. Isolated cases of ileal perforation due to CMV infection have never been reported in a SLE patient. Thus, chronic right lower abdominal pain, fever with or without diarrhea in immunocompromised patients should cause clinicians to consider CMV ileitis in the differential diagnosis. Immediate surgical resection and prompt antiviral therapy lead to successful treatment.
