“Highly active antiretroviral therapy (HAART) has dramatically changed the natural history of HIV infection in

children, but there are few studies in the literature about the incidence of clinical manifestations after HAART in this population, compared with adults. The aim of this study was to describe the influence of the widespread use of HAART on the development of opportunistic infections and organ-specific diseases in HIV-infected children. An observational selleck screening library study of a cohort of 366 vertically HIV-infected children followed from 1990 to 2006 was carried out. According to the main antiretroviral protocol used, three calendar periods (CPs) were defined and compared: CP1 (1990–1996: no patients on HAART), CP2 (1997–1999: <60% on HAART) and CP3 (2000–2006: >60% on HAART). Children experienced a progressive increase in CD4 T cell count (P<0.05) and a decrease in HIV viral load from 1996

onwards (P<0.05). Similarly, rates of death, AIDS, opportunistic infections (bacteraemia, candidosis, cryptosporidiosis and bacterial pneumonia) and organ-specific diseases (wasting syndrome, thrombocytopenia, cardiomyopathy, lymphoid interstitial pneumonia and HIV-associated encephalopathy) were lower in CP2 and CP3 than in CP1. This study provides evidence of improved clinical outcomes in HIV-infected children over time and shows that mortality, AIDS, opportunistic infections and organ-specific diseases declined as HAART was progressively instituted in this population. In selleck inhibitor developed countries, the number of children receiving highly active antiretroviral therapy (HAART) has increased since 1996. Around 20% of untreated children

with vertical HIV transmission would have severe immunodeficiency by the age of 1 year and approximately 75% by the age of 10 years [1]. HAART has markedly reduced morbidity and mortality among HIV-infected children, being associated with a substantial increase in CD4 T-lymphocyte count and a decrease in HIV viral load [2–5]. In addition, rates of opportunistic infections (OIs) and organ-specific diseases (OSDs) Loperamide have also diminished with the use of HAART [6]. However, OIs still occurred in the HAART era, mainly in children with persistently low CD4 T-lymphocyte counts [7–10]. There are some specific issues related to paediatric, as opposed to adult, HIV infection. For example, the number of available formulations is limited. There is also a scarcity of clinical trials in children, and insufficient data on the efficacy and toxicity of antiretrovirals for paediatric use, and on the long-term consequences of perinatally acquired HIV infection and drug toxicity. In the last few decades, outcomes for HIV-infected children and adolescents have improved dramatically with the widespread use of antiretrovirals, despite delayed introduction of their use in this population relative to the adult population.
