| Abstract: | Rationale:The presentation of multiple intestinal perforations is a severe complication of enteric cytomegalovirus (CMV) infection, sometimes associated with immune reconstitution inflammatory syndrome (IRIS) after the initiation of antiretroviral therapy (ART) in patients with human immunodeficiency virus (HIV). Here we reported a rare case of a patient with HIV infection who developed multiple perforations in the small bowel shortly after ART initiation without any prodromal gastrointestinal symptoms. We also reviewed the literature of reported cases to clarify their clinical characteristics for early diagnosis and rapid intervention.Patient concerns:A patient with HIV presented with fever after 16 days of ART initiation and was admitted to our hospital. He was treated with intravenous ganciclovir due to persistent CMV viremia. The fever resolved 10 days later. However, he reported persistent left lower abdominal pain.Diagnoses:The patient was diagnosed with multiple small bowel perforations, CMV-related IRIS, and acquired immune deficiency syndrome. An upright abdominal x-ray in a tertiary level hospital revealed bilateral moderate intraperitoneal free air. We performed a pathological examination and metagenomic next-generation sequencing. CMV enteritis was confirmed by immunohistochemical staining and other opportunistic infections were excluded by metagenomic next-generation sequencing.Interventions:The patient was treated with intravenous ganciclovir and 24 hours later, the patient underwent exploratory laparotomy. Partial resection and surgical repair of the small intestine were performed.Outcomes:The patient ultimately died from intestinal obstruction and septic shock 55 days after surgery.Lessons:Perforations due to CMV-related IRIS are very rare, and usually appear shortly after ART initiation. Most cases lack the prodromal symptoms of abdominal pain and diarrhea. Intestinal perforations are lethal, and early detection and surgical treatment are lifesaving. |
