BACKGROUND Successful antiretroviral therapy (ART) has dramatically reduced mortality among HIV-infected children. However, there is growing concern about long-term effects associated to ART. The aim of this study was to determine the prevalence of metabolic abnormalities in a cohort of perinatally HIV-infected adolescents and young adults and to identify(More)
BACKGROUND Mycobacterium lentiflavum is considered a rare pathogen causing nontuberculous mycobacterial (NTM) lymphadenitis. METHODS A multicenter, retrospective study was performed in immunocompetent children <14 years of age with microbiologically confirmed NTM lymphadenitis treated at 6 hospitals in Madrid, Spain, during 2000-2010. We compared children(More)
Since the implementation of highly active antiretroviral therapy in HIV-infected children, response to scheduled vaccines may determinate future morbidity and mortality. The aims of this study have been to describe the current vaccine coverage, vaccine safety and concordance with vaccine recommendations of the 68 HIV-infected children and adolescents(More)
The presence of autoantibodies and autoimmune diseases was tested in all available members of five families with at least one member affected with X-linked chronic granulomatous disease. Patients and carriers relatives possess autoantibodies more frequently than non-carriers relatives (95% vs 10%, p < 1.0 x 10(-5), Fisher test). Further, a survey of the(More)
BACKGROUND Mother-to-child transmission (MTCT) during pregnancy, delivery or breastfeeding, is the main route of HIV infection in children. Strategies aimed at promoting the health of HIV infected pregnant women and MTCT prevention have reduced transmission to below 2%. This paper presents the clinical and epidemiological features of a cohort from Madrid(More)
We evaluated the evolution over time of once-daily antiretroviral therapy in HIV-infected children and its relationship with adherence. An increase on the prevalence of once-daily antiretroviral therapy was observed over time (from 0.9% in 2002 to 44.2% in 2011). There was no difference in adherence regarding once-daily or BID regimens in 2011. Adherence(More)
Reported synonymous substitutions are generally non-pathogenic, and rare pathogenic synonymous variants may be disregarded unless there is a high index of suspicion. In a case of IL7 receptor deficiency severe combined immunodeficiency (SCID), the relevance of a non-reported synonymous variant was only suspected through the use of additional in silico(More)
INTRODUCTION Thanks to advances in antiretroviral treatment, children with HIV infections through vertical transmission have improved their life expectancy. However, new challenges have emerged. We propose this study in order to determine the psychosocial aspects and knowledge of infections in a cohort of adolescents with vertically transmitted HIV(More)
INTRODUCTION Cytomegalovirus (CMV) is the leading cause of congenital infection worldwide. Data about the management of CMV infection in pregnant women are scarce, and treatment options are very limited. The aim of the study is to investigate the effectiveness of cytomegalovirus hyperimmune globulin (CMV-HIG) for the prevention and treatment of congenital(More)
