[Portal hypertension and HIV infection].
In the era of antiretroviral therapies, the outcome of patients with chronic HIV infection has considerably changed and their prolonged survival allows the development of chronic liver diseases as a major cause of mortality. Although viral hepatitis, alcoholic and non alcoholic steatohepatitis account forthe majority of chronic liver damage in these patients, there is a growing number of cases with unexplained liver disease, many of which are associated with clinical manifestations of portal hypertension. Inthissituation, nodularregenerative hyperplasia is a frequent finding, characterized at histology by the presence of a nodular architecture in the absence of significant fibrosis, resulting from progressive obliteration of small portal veins. This article describes the clinical presentation, diagnostic aspects, pathogenic mechanisms, as well as the management of this emergent non cirrhotic liver disease in HIV-infected patients.
