A second child who had peninatally transmitted AIDS was noted to have cholangitis at autopsy. Sonognaphic examination at 1 year of age showed normal caliber of the biliany tract. She died of cardionespiratony arrest following an episode of Pneuomocystis carinll pneumonia 4 months after sonographic evaluation. At autopsy, cholangiolan proliferation, bile plugging, and numerous peniductal neutrophils were noted. AIDS-related acalculous biliary tract disease is a newly recognized abnormality in children. No reports of cholangitis in this population have been reported. The condition may currently be underestimated, as clinical diagnosis is difficult [1 , 3, 4]. Clinical features in the cases reported were nonspecific. Hepatomegaly was noted; however, that is a frequent clinical finding in children who have AIDS [6]. Jaundice was not present in either of our cases. The liver function profile of these children was variable. Transaminase levels were elevated in one child, and results of liver function tests were normal in the other. A cholestatic pattern of liver function test abnormalities, characterized by disproportionate elevation of serum levels of alkaline phosphatase and total bilirubin levels relative to transaminase levels, has been reported in many adult patients who have AIDS-related cholangitis [i , 3-5]. This pattern was not observed in either child in this report, indicating that biliary obstruction was incomplete.

1 week after sonography also showed biliary dilatation. Extrinsic masses were not identified at either sonography or CT. Abdominal sonography was repeated 3 and 8 weeks after the initial study. Follow-up scans continued to show biliary tract dilatation and gallbladder wall thickening. The child did not have jaundice. She died 8 months later of cardiorespiratory arrest. At autopsy, extensive involvement of the liver by suppurative cholangitis with bacterial overgrowth and abscess measured

Proposed causes of AIDS-related biliary tract disease in adults include the following: (1) biliary inflammation due to the immune

(2) direct

mucosa by HIV; and (3) secondary infection by opportunistic organisms that frequently involve the gastrointestinal tract, such as Cryptosporidium, cytomegalovirus, on Candida albicans [1 -5]. Cryptosporidium was isolated from the stool in one of the cases presented. The underlying pathogenesis in the other child is unclear. Bile sampling was not obtained, and AIDS-specific pathogens were not isolated from the blood or stool. Histologic evidence of cytomegalovinus was not present at autopsy. A variety
