Intestinal perforation due to hemorrhagic Cytomegalovirus enteritis in a patient with severe uncontrolled lupus nephritis: a case and review of the literature.

A 31-year-old woman with systemic lupus erythematosus and lupus nephritis was treated with prednisone and immunosuppressants. After her lupus nephritis symptoms worsened, both high-dose steroid and cyclophosphamide pulse therapy were administered. The patient developed an intestinal perforation, and laparoscopic Hartmann's surgery was performed on the sigmoid colon. Serum Cytomegalovirus (CMV) antigen C7HRP was detected, and the patient was diagnosed with CMV colitis and underwent a colon resection. Severe hematochezia continued despite ganciclovir administration, and the patient underwent laparoscopic total colectomy and partial ileostomy. CMV enteritis should be considered in patients treated with prednisone and immunosuppressants and those who have abdominal pain and hematochezia. Immunocompromised patients with intestinal perforation due to CMV enteritis have a poor prognosis. We report a case with along with the results of a literature review.
