HIV/AIDS cholangiopathy: clinical spectrum, cholangiographic features and outcome in 30 patients

Background and Aims: AIDS cholangiopathy is presently considered rare and has been reported mainly from the West. With the HIV epidemic in India, we have encountered an increasing number of patients. We aimed to study these patients and determine differences from earlier experiences. Methods: We describe the clinical presentation, cholangiographic features, and outcome and determine differences reported in Western literature. Results: From Jan 1999 to May 2009, 30 patients (27 men) with AIDS cholangiopathy were seen. The most common mode of transmission was heterosexual (n = 28) followed by blood transfusion (n = 2). Abdominal pain (n = 20) of biliary origin, was the commonest manifestation followed by an asymptomatic group (n = 6) and a third group (n = 3) with pain due to pancreatitis. Ultrasonography of the abdomen was abnormal in all patients. Papillary stenosis (n = 23) was the most common cholangiographic feature followed by sclerosing cholangitis (n = 5). Abdominal pain resolved reliably and promptly after endoscopic sphincterotomy. Cholangiographic abnormalities regressed during follow up on antiretroviral therapy in 10 patients. Seven patients on anti retroviral therapy developed de novo cholangiopathy, with a precipitous drop in CD4 count of whom two had a worse prognosis. None had Kaposi's sarcoma. Conclusions: In contrast to Western literature, HIV cholangiopathy was seen predominantly in patients who acquired HIV by heterosexual transmission. De novo development of cholangiopathy on antiretroviral therapy may indicate the occurrence of resistance. Papillary stenosis is the most common feature. Abdominal pain resolved with sphincterotomy. Regression of cholangiographic abnormality occurred with anti retroviral medications. Median survival following cholangiopathy diagnosis was 34 months, higher than reported in previous studies.
