Abstract
Due to the widespread access to, and implementation of, combination antiretroviral therapy, individuals perinatally infected with human immunodeficiency virus type 1 (HIV-1) are living into adolescence and adulthood. Perinatally infected adolescents living with HIV-1 (pALHIV) are plagued by progressive, chronic neurocognitive impairments; the pathophysiological mechanisms underlying these deficits, however, remain understudied. A longitudinal experimental design from postnatal day (PD) 30 to PD 180 was utilized to establish the development of pyramidal neurons, and associated dendritic spines, from layers II-III of the medial prefrontal cortex (mPFC) in HIV-1 transgenic (Tg) and control animals. Three putative neuroinflammatory markers (i.e., IL-1β, IL-6, and TNF-α) were evaluated early in development (i.e., PD 30) as a potential mechanism underlying synaptic dysfunction in the mPFC. Constitutive expression of HIV-1 viral proteins induced prominent neurodevelopmental alterations and progressive synaptodendritic dysfunction, independent of biological sex, in pyramidal neurons from layers II-III of the mPFC. From a neurodevelopmental perspective, HIV-1 Tg rats exhibited prominent deficits in dendritic and synaptic pruning. With regards to progressive synaptodendritic dysfunction, HIV-1 Tg animals exhibited an age-related population shift towards dendritic spines with decreased volume, increased backbone length, and decreased head diameter; parameters associated with a more immature dendritic spine phenotype. There was no compelling evidence for neuroinflammation in the mPFC during early development. Collectively, progressive neuronal and dendritic spine dysmorphology herald synaptodendritic dysfunction as a key neural mechanism underlying chronic neurocognitive impairments in pALHIV.

Abstract
Background: Combined antiretroviral therapy (cART) has been associated with a steep decrease in mortality and morbidity in HIV-1 infected children. New antiretroviral molecules and drug classes have been developed and the management of HIV-infected children has improved, but recent data on survival are limited. Methods: An observational retrospective study investigating changes in mortality and morbidity was conducted on 1,091 perinatally HIV-1 infected children enrolled in the Italian Register for HIV Infection in Children and followed-up from 2001 to 2018. Results: Three hundred and fifty-four (32%) AIDS events and 26 (2%) deaths occurred overtime. Mortality rates decreased from 0.4/100 person-years in 2001-2006 to 0.27/100 person-years in 2007-2012 and 0.07/100 person-years in 2013-2018. Notably, 92% of the dead children were born in Italy, but only 50% were followed-up since birth or within three months of age. Seventy three percent of children had started cART at age ≥6 months; 23% were treated for <30 days before death. B and C clinical events progressively decreased (P < 0.0001). Opportunistic infections significantly decreased over time, but still were the most common events in all the periods (6.76/100 person-years in 2013-2018). In the last period, severe bacterial infections were the most common ones. Cancer rates were 0.07/100; 0.17/100; 0.07/100 person-years in the three periods, respectively. Conclusions: Progressive reductions both in mortality and in rates of class B and C clinical events and OIs have been observed during the cART era. However, deaths were still registered; more than half of dead children were enrolled after birth and had belatedly started cART.

Abstract
Parasites can increase infection rates and pathogenicity in immunocompromised human immunodeficiency virus (HIV) patients. However, in vitro studies and epidemiological investigations also suggest that parasites might escape immunocompromised hosts during HIV infection. Due to the lack of direct evidence from animal experiments, the effects of parasitic infections on immunocompromised hosts remain unclear. Here, we detected 14 different parasites in six northern pig-tailed macaques (NPMs) before or at the 50th week of simian immunodeficiency virus (SIV) infection by ELISA. The NPMs all carried parasites before viral injection. At the 50th week after viral injection, the individuals with negative results in parasitic detection (i.e., 08247 and 08287) were characterized as the Parasites Exit (PE) group, with the other individuals (i.e., 09203, 09211, 10205, and 10225) characterized as the Parasites Remain (PR) group. Compared with the PR group, the NPMs in the PE group showed higher viral loads, lower CD4+ T cells counts, and lower CD4/CD8 rates. Additionally, the PE group had higher immune activation and immune exhaustion of both CD4+ and CD8+ T cells. Pathological observation showed greater injury to the liver, cecum, colon, spleen, and mesenteric lymph nodes in the PE group. This study showed more seriously compromised immunity in the PE group, strongly indicating that parasites might exit an immunocompromised host.

Abstract
PURPOSE OF REVIEW It is 20 years since the start of the combination antiretroviral therapy (cART) era and more than 10 years since cART scale-up began in resource-limited settings. We examined survival of vertically HIV-infected infants and children in the cART era. RECENT FINDINGS Good survival has been achieved on cART in all settings with up to 10-fold mortality reductions compared with before cART availability. Although mortality risk remains high in the first few months after cART initiation in young children with severe disease, it drops rapidly thereafter even for those who started with advanced disease, and longer term mortality risk is low. However, suboptimal retention on cART in routine programs threatens good survival outcomes and even on treatment children continue to experience high comorbidity risk; infections remain the major cause of death. Interventions to address infection risk include a cotrimoxazole prophylaxis, isoniazid preventive therapy, routine childhood and influenza immunization, and improving maternal survival. SUMMARY Pediatric survival has improved substantially with cART and HIV-infected children are aging into adulthood. It is important to ensure access to diagnosis and early cART, good program retention as well as optimal comorbidity prophylaxis and treatment to achieve the best possible long-term survival and health outcomes for vertically infected children.

Abstract
OBJECTIVES To assess the risks of and factors associated with mortality, loss to follow-up, and changing regimens after children with HIV infected perinatally initiate combination antiretroviral therapy (cART) in Latin America and the Caribbean. STUDY DESIGN This 1997-2013 retrospective cohort study included 1174 antiretroviral therapy-naïve, perinatally infected children who started cART age when they were younger than 18 years of age (median 4.7 years; IQR 1.7-8.8) at 1 of 6 cohorts from Argentina, Brazil, Haiti, and Honduras, within the Caribbean, Central and South America Network for HIV Epidemiology. Median follow-up was 5.6 years (IQR 2.3-9.3). Study outcomes were all-cause mortality, loss to follow-up, and major changes in cART. We used Cox proportional hazards models stratified by site to examine the association between predictors and times to death or changing regimens. RESULTS Only 52% started cART at younger than 5 years of age; 19% began a protease inhibitor. At cART initiation, median CD4 count was 472 cells/mm3 (IQR 201-902); median CD4% was 16% (IQR 10-23). Probability of death was high in the first year of cART: 0.06 (95% CI 0.04-0.07). Five years after cART initiation, the cumulative mortality incidence was 0.12 (95% CI 0.10-0.14). Cumulative incidences for loss to follow-up and regimen change after 5 years were 0.16 (95% 0.14-0.18) and 0.30 (95% 0.26-0.34), respectively. Younger children had the greatest risk of mortality, whereas older children had the greatest risk of being lost to follow-up or changing regimens. CONCLUSIONS Innovative clinical and community approaches are needed for quality improvement in the pediatric care of HIV in the Americas.

Abstract
Este estudo tem como objetivo avaliar o uso da terapia antirretroviral combinada em crianças e adolescentes com AIDS. Foram captados 247 resumos nos portais PubMed e LILACS, publicados entre 1983 e 2013, sendo utilizados 69 artigos para as referências bibliográficas. A atenção atribuída às pesquisas na faixa etária pediátrica durante os trinta anos de epidemia de AIDS se justifica por características imunológicas próprias, sendo a progressão da AIDS mais rápida em crianças que em adultos. Pesquisas recentes abordam estratégias de intervenção medicamentosa de alta potência antes do aparecimento dos sintomas iniciais. A introdução precoce da terapia antirretroviral combinada foi implantada com eficácia e segurança em populações com poucos recursos fixos, com melhora significativa da sobrevida desses pacientes. O desafio atual é lidar com uma doença crônica com intercorrências agudas. Novas pesquisas serão necessárias, atentando para as especificidades populacionais e particularizando as necessidades individuais dos pacientes pediátricos.

Abstract
OBJECTIVES To describe demographic and treatment characteristics of the Dutch vertically HIV-infected paediatric population from 1996 to 2012, and to investigate the long-term virological and immunological response to combination antiretroviral therapy (cART), with emphasis on the influence of age at cART initiation and initial CD4 cell counts. DESIGN Descriptive cohort study. METHODS From 1996 to 2012, all paediatric HIV clinics in the Netherlands provided data on their HIV-infected population. Descriptive statistics, parametric and non-parametric comparative tests, and random-effects linear regression models were performed to investigate the different aspects of this cohort. RESULTS A total of 229 vertically HIV-infected children were included. The majority of all mothers (64%) and almost half of the children (43%) originated from sub-Saharan Africa. Ritonavir-boosted lopinavir and efavirenz have replaced indinavir, nelfinavir and nevirapine as preferred first-line cART regimens. Long-term CD4 T-cell reconstitution (with CD4 cell counts corrected for age) was independent of age and CD4 cell count at cART initiation. The decline in HIV viral load after cART introduction occurred faster over the studied time period. The percentage of children with an undetectable viral load rose substantially from 1996 to 2012. Mortality was 0.3 per 100 person-years. CONCLUSION A sustained immunological response in the Dutch paediatric HIV-infected population was independent of age as well as CD4 cell count at cART initiation, despite a higher initial HIV viral load in the youngest children. The percentage of children with an undetectable HIV viral load rose substantially over the years and there was a low mortality rate in comparison with reports from other industrialized countries.

Abstract
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.

Abstract
BACKGROUND Information on the use of new antiretroviral drugs in children in the real setting of clinical fields is largely unknown. METHODS Data from 2554 combined antiretroviral therapy (cART) regimens administered to 911 children enrolled in the Italian Register for HIV infection in children, between 1996 and 2009, were analysed. Factors potentially associated with undetectable viral load and immunological response to cART were explored by Cox regression analysis. RESULTS Proportion of protease inhibitor (PI)-based regimens significantly decreased from 88.0% to 51.2% and 54.9%, while proportion on non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens increased from 4.5% to 38.8% and 40.2% in 1996-1999, 2000-2004 and 2005-2009, respectively (p < 0.0001). Significant change in the use of each antiretroviral drug occurred over the time periods (p < 0.0001). Factors independently associated with virological and immunological success were as follows: later calendar periods, younger age at regimen (only for virological success) and higher CD4(+) T-lymphocyte percentage at baseline. Use of unboosted PI was associated with lower adjusted hazard ratio (aHR) of virological or immunological success with respect to NNRTI- and boosted PI-based regimens, with no difference among these two latter types. CONCLUSION Use of new generation antiretroviral drugs in Italian HIV-infected children is increasing. No different viro-immunological outcomes between NNRTI- and boosted PI-based cART were observed.

Abstract
OBJECTIVE Treatment with highly active antiretroviral therapy (HAART) reduces overall perinatal human immunodeficiency virus (HIV) type 1-related mortality. The effect of timing of HAART initiation on reduction of morbidity is not well defined. We evaluated the association of timing of HAART initiation on progression to moderate or severe disease. METHODS Retrospective, population-based study of 196 perinatally HIV-infected children followed from birth in northern California from 1988 to 2009. RESULTS Of 196 children, 58% received HAART and were followed for a median of 6.2 years after HAART initiation. HAART use was associated with improved survival to the age of 5 years: no HAART, 50% versus HAART, 88%; P < 0.0001. However, the advantage of initial HAART over mono or dual therapy transitioning to HAART was small and not statistically significant (P = 0.23). Starting HAART before the development of moderate or severe disease delayed the median age of diagnosis of moderate disease from 0.4 years (interquartile range, [0.3-0.8]) without HAART to 3.0 years ([interquartile range, 1.9-5.8]; P < 0.0001) with HAART. HAART initiation after progression to moderate or severe disease was associated with decreased progression to severe disease or death, respectively (moderate to severe: 8% [3/36] with HAART vs. 84% [70/83] with no HAART, P < 0.0001; severe to death: 9% [6/68] with HAART vs. 73% [49/67] with no HAART, P < 0.0001). CONCLUSIONS In perinatal HIV infection, HAART is associated with delayed progression and reduced mortality regardless of disease severity at HAART initiation. This finding reinforces US guidelines regarding HAART initiation at >1 year of age if children present with most clinical category B diagnoses, regardless of CD4 measurements or plasma HIV RNA level.
