title: Effect of antiretroviral therapy on pulmonary hypertension in HIV patients.
abstract: Pulmonary hypertension is an important cause of dyspnoea in human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) patients. The effect highly active antiretroviral therapy on pulmonary artery pressure has been an area of controversy. The purpose of this study was to evaluate the effect of antiretroviral therapy on pulmonary hypertension in HIV patients. This prospective cohort study was performed in a peripheral medical college of West Bengal with 88 patients from October 2008 to September 2011. By echocardiography, pulmonary artery pressure was recorded before initiation of antiretroviral therapy. After one year of antiretroviral therapy repeat echocardiography was done and pulmonary artery pressure was evaluated. The values were analysed. The present study showed that highly active antiretroviral therapy improves pulmonary artery pressure in HIV/AIDS patients if instituted at early stages (WHO classes I and II). However, at more advanced stages of pulmonary artery hypertension, it does not have any significant effect on reduction of the same. The present study documents that early detection of pulmonary artery hypertension in HIV/AIDS patients is essential and prompt institution of highly active antiretroviral therapy should be considered in them even when those patients do not fulfill the conventional criteria for initiation of this treatment.
