Cytomegaloviral acalculous cholecystitis in acquired immunodeficiency syndrome patients.

Abdominal pain and fever in patients with the acquired immunodeficiency syndrome (AIDS) may indicate cytomegaloviral (CMV) acalculous cholecystitis. We reviewed clinical, laboratory, and outcome data from 12 patients with CMV cholecystitis. Ten of 12 patients were homosexual males. Six patients had markedly low CD4: CD8 lymphocyte count ratios. Total leukocyte counts were normal or decreased, serum liver function tests normal or cholestatic, and only one patient had hyperbilirubinemia. Sonographic transmural gallbladder edema is typically more severe than expected for the presenting illness. Five of six patients investigated with HIDA scintigraphy had a nonvisualizing gallbladder. Open cholecystectomy had a 9.1 per cent operative morbidity and a 0 per cent mortality. Cholecystectomy is a safe and curative intervention, regardless of the immunocompromised condition of the host. Intraoperative cholangiography will identify papillary stenosis or sclerotic bile ducts as a potential cause of recurrent symptoms following surgery. A search for other sites of tissue invasion by CMV should follow cholecystectomy.
