Nine-year follow-up of HIV-infected Romanian children and adolescents receiving lopinavir/ritonavir-containing highly active antiretroviral therapy

Introduction Many Romanian children were infected nosocomially with human immunodeficiency virus (HIV) in the late 1980s. The Romanian-American Children's Center of Excellence in Constanţa continues to follow approximately 450 of these patients. In 2001, 414 of these patients were initiated on triple therapy including lopinavir/ritonavir. Data from this cohort treated through August 2006 were published in April 2007 demonstrating that the treatment was well tolerated, with 337 children (81%) remaining on therapy after a median duration of >4 years. The current article describes the results of continued analysis of this cohort through end 2010. The objective of the study was to determine the long-term clinical outcomes of children and adolescents commenced on antiretroviral therapy (ART) including lopinavir/ritonavir.
