There are approximately from 1,100 to 1,200 HIV-infected children in a follow-up in Spain. In 2008 an open, multicentral, retrospective and prospective Cohort of the Spanish Paediatric HIV Network (CoRISpe) was founded. The CoRISpe is divided into the node 1 and node 2 representing geographically almost the whole territory of Spain. Since 2008 seventy-five hospitals have been participating in the CoRISpe. All the retrospective data of the HIV-infected children have been kept in the CoRISpe since 1995 and prospective data since 2008. In this article we are going to present the notion of CoRISpe, its role, the structure, how the CoRISpe works and the process how a child is transferred from Paediatric to Adults Units.The main objective of the CoRISpe is to contribute to furthering scientific knowledge on paediatric HIV infection by providing demographic, sociopsychological, clinical and laboratory data from HIV-infected paediatric patients. Its aim is to enable high-quality research studies on HIV-infected children.
Our data suggest that lopinavir-ritonavir salvage therapy led not only to a viral load decrease but also to a phenotypic change. X4 virus appeared to be preferentially suppressed. Shifts in co-receptor usage may thereby contribute to the clinical efficacy of anti-HIV drugs in vertically infected infants.
We performed a retrospective observational study of 253 children vertically infected with human immunodeficiency virus (1994-2001) to assess the effectiveness of antiretroviral therapies (ARTs) on survival and surrogate markers at the population level. Children were divided into 3 groups according to the ART protocols used during the follow-up period: calendar period (CP) 1 (1994-1996) received combined therapy with 2 nucleoside reverse transcriptase inhibitors (NRTIs); CP2 (1997-1998) received implementation of highly active ART (HAART) with 3 drugs (NRTIs, protease inhibitors, and non-NRTIs); and CP3 (1999-2001) received extensive HAART. The children in the CP3 group had statistically significant longer survival periods, lower virus load (VL), highest undetectable VL proportion, and highest CD4+ T cell counts. HAART is effective at the population level at decreasing VL, increasing CD4+ T cells, and increasing the survival in a higher percentage of HIV-infected children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
