RESUMEN

BACKGROUND: Published estimates of mortality and progression to AIDS as children with HIV approach adulthood are limited. We describe rates and risk factors for death and AIDS-defining events in children and adolescents after initiation of combination antiretroviral therapy (cART) in 17 middle- and high-income countries, including some in Western and Central Europe (W&CE), Eastern Europe (Russia and Ukraine), and Thailand. METHODS AND FINDINGS: Children with perinatal HIV aged <18 years initiating cART were followed until their 21st birthday, transfer to adult care, death, loss to follow-up, or last visit up until 31 December 2013. Rates of death and first AIDS-defining events were calculated. Baseline and time-updated risk factors for early/late (≤/>6 months of cART) death and progression to AIDS were assessed. Of 3,526 children included, 32% were from the United Kingdom or Ireland, 30% from elsewhere in W&CE, 18% from Russia or Ukraine, and 20% from Thailand. At cART initiation, median age was 5.2 (IQR 1.4-9.3) years; 35% of children aged <5 years had a CD4 lymphocyte percentage <15% in 1997-2003, which fell to 15% of children in 2011 onwards (p < 0.001). Similarly, 53% and 18% of children ≥5 years had a CD4 count <200 cells/mm3 in 1997-2003 and in 2011 onwards, respectively (p < 0.001). Median follow-up was 5.6 (2.9-8.7) years. Of 94 deaths and 237 first AIDS-defining events, 43 (46%) and 100 (42%) were within 6 months of initiating cART, respectively. Multivariable predictors of early death were: being in the first year of life; residence in Russia, Ukraine, or Thailand; AIDS at cART start; initiating cART on a nonnucleoside reverse transcriptase inhibitor (NNRTI)-based regimen; severe immune suppression; and low BMI-for-age z-score. Current severe immune suppression, low current BMI-for-age z-score, and current viral load >400 c/mL predicted late death. Predictors of early and late progression to AIDS were similar. Study limitations include incomplete recording of US Centers for Disease Control (CDC) disease stage B events and serious adverse events in some countries; events that were distributed over a long time period, and that we lacked power to analyse trends in patterns and causes of death over time. CONCLUSIONS: In our study, 3,526 children and adolescents with perinatal HIV infection initiated antiretroviral therapy (ART) in countries in Europe and Thailand. We observed that over 40% of deaths occurred ≤6 months after cART initiation. Greater early mortality risk in infants, as compared to older children, and in Russia, Ukraine, or Thailand as compared to W&CE, raises concern. Current severe immune suppression, being underweight, and unsuppressed viral load were associated with a higher risk of death at >6 months after initiation of cART.

RESUMEN

UNLABELLED: Advances in care and antiretroviral treatment, improved life expectancy and quality of life in children with perinatally-acquired human immunodeficiency virus (HIV) infection. There is increasing interest in the chronic effects of growing up with HIV. The aim of this study was to assess the psychosocial, emotional and behavioural functioning in a cohort of perinatally-acquired HIV-infected adolescents. Data were obtained through semi-structured interviews and the Strengths and Difficulties Questionnaire (SDQ) for emotional and behavioural disorders screening. RESULTS: A total of 95 patients (58% women) were assessed with a median age of 15 years (11-19.1) and a median age at diagnosis of 1.7 years (0-12.2). The median CD4 count, at the inclusion, was 626 cells/mm(3) (132-998), with 34% (10-52%). Viral load was <50 copies/ml in 72% of patients. Eighty-one per cent knew their diagnosis and optimal adherence was achieved in 53%. Passive coping was reported in 58.4% of the adolescents. Only 7.7% of teenagers had a complete and adequate knowledge of their disease and only 18.2% had shared it with their friends. Six unwanted pregnancies occurred (11% of women). Most of them (90%) attended school but 60% had been held back one or more school years. Overall, SDQ scored a risk of behavioural and emotional problems in 24.5%. The report of behaviours associated with hyperactivity was high in 14.9% of the population and borderline in 18.1%. Adolescents with encephalopathy accounted for 44% of those whose total scores fell in either the abnormal and borderline ranges for emotional difficulties (p = .038). CONCLUSION: Perinatally-acquired HIV-infected adolescents showed significant psychosocial and behavioural health risks that should bring attention to prevention and health care programmes. An earlier disclosure to children could favour a better psychological adjustment and a better treatment adherence. Future studies are needed to assess the relationship between vertically acquired HIV-infection and hyperactivity.

RESUMEN

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 associated factors. METHODS: We present results from a cross-sectional analysis including individuals 12 to 20 years of age, from a prospective, longitudinal cohort of perinatally-acquired HIV-infected children, adolescents and young adults in Madrid. Clinical and immunological data were recorded and complete lipid and glycemic profiles were determined. RESULTS: Ninety-nine adolescents were included, with a median age of 15.3 years [13.6-16.7]. Patients with abnormal levels of lipids were as follows: 27.2% total cholesterol ≥200 mg/dl, 25.9% LDL cholesterol (LDL-c) ≥ 130 mg/dl, 14.1% HDL-C < 35 mg/dl and 39.8% triglycerides ≥ 150 mg/dl. Current use of protease inhibitors (PI) was associated with higher triglyceride values (p = 0.022). Four (4.6%) patients showed fasting glucose ≥ 100 mg/dl and 30.6% presented with insulin resistance (IR) (HOMA-IR over the 90th centile). In the multivariate logistic regression analysis adjusted for sex, age, weight, Tanner stage, protease inhibitors (PI) and nucleoside reverse transcriptase inhibitors (NRTI) treatment length and CD4 nadir, IR was associated with higher waist circumference Z score; OR: 3.92(CI95%: 1.15-13.4) (p = 0.03). CONCLUSION: There was a high prevalence of insulin resistance and lipid abnormalities in this cohort of perinatally-acquired HIV-infected adolescents. A simple clinical measurement like waist circumference Z score might be a reliable marker and predictor of insulin resistance in these patients.

RESUMEN

BACKGROUND: Antiretroviral therapy (ART) in pregnancy has resulted in a marked impact on reducing the risk of mother-to-child transmission (MCT) of HIV. However the safety of in utero ART exposure in newborns remains a concern. METHODS: A multicenter prospective observational study of HIV-infected mother and their infants was performed in Madrid, Spain, from 2000 to 2009. Children had regular visits with clinical examination according to protocol until the age of 24 months. An abdominal ultrasound and an echocardiogram were scheduled during follow up. Birth defects (BDs) were registered according to European Surveillance of Congenital Anomalies (EUROCAT). RESULTS: A total of 897 live births from 872 mothers were included. Overall the birth defects prevalence observed was 6.9% (95% CI 5.4-9.1).The most commonly reported birth defects types were in genital organs and urinary system (19 cases, 30.6%) and cardiovascular system (17 cases, 27.4%). There was no increased risk for infants exposed in the first trimester to ARVs compared with unexposed infants. No significant associations were observed between exposure to any individual antiretroviral agent during pregnancy and birth defects CONCLUSION: A higher prevalence of BDs was observed, higher than previously reported. In utero exposure to ART was not proved to be a major risk factor of birth defects in infants. However the relatively small number of patients is a major limitation of this study.

RESUMEN

The main objective in the management of HIV-infected pregnant women is prevention of mother-to-child transmission; therefore, it is essential to provide universal antiretroviral treatment, regardless of CD4 count. All pregnant women must receive adequate information and undergo HIV serology testing at the first visit. If the serological status is unknown at the time of delivery, or in the immediate postpartum, HIV serology testing has to be performed as soon as possible. In this document, recommendations are made regarding the health of the mother and from the perspective of minimizing mother-to-child transmission.

RESUMEN

OBJECTIVE: The main objective in the management of HIV-infected pregnant women is prevention of mother-to-child transmission; therefore, it is essential to provide universal antiretroviral treatment, regardless of CD4 count. All pregnant women must receive adequate information and undergo HIV serology testing at the first visit. METHODS: We assembled a panel of experts appointed by the Secretariat of the National AIDS Plan (SPNS) and the other participating Scientific Societies, which included internal medicine physicians with expertise in the field of HIV infection, gynecologists, pediatricians and psychologists. Four panel members acted as coordinators. Scientific information was reviewed in publications and conference reports up to November 2012. In keeping with the criteria of the Infectious Diseases Society of America, 2levels of evidence were applied to support the proposed recommendations: the strength of the recommendation according to expert opinion (A, B, C), and the level of empirical evidence (I, II, III). This approach has already been used in previous documents from SPNS. RESULTS AND CONCLUSIONS: The aim of this paper was to review current scientific knowledge, and, accordingly, develop a set of recommendations regarding antiretroviral therapy (ART), regarding the health of the mother, and from the perspective of minimizing mother-to-child transmission (MTCT), also taking into account the rest of the health care of pregnant women with HIV infection. We also discuss and evaluate other strategies to reduce the MTCT (elective Cesarean, child's treatment…), and different aspects of the topic (ARV regimens, their toxicity, monitoring during pregnancy and postpartum, etc.).

RESUMEN

Congenital transmission of Chagas disease now occurs in areas where the disease is non-endemic, and also from one generation to another. According to epidemiological data from Latin America, the prevalence of the disease in pregnant women is 0.7%-54%, and the prevalence of vertical transmission is around 5%-6%. Congenital T. cruzi infection is an acute infection in newborns that should be treated with anti-parasitic therapy. The treatment of pregnant women could also have an impact on the control of the disease. This article has been prepared following the recommendations suggested by a group of experts in Infectious Diseases, Microbiology, Gynaecology and Paediatrics.

RESUMEN

INTRODUCTION: The number of children of immigrant origin in the last few years has increased the cohort of HIV-infected children in the Community of Madrid. The objectives of the study were to evaluate the epidemiological and clinical characteristics of the new diagnosed children and describe the different subtypes of HIV-1. PATIENTS AND METHODS: The new diagnosed children were analysed from the year 1997, divided into 3 periods: P1 (1997-2000), P2 (2001-2004), P3 (2005-2009). The regions and countries of origin, the clinical, immune and viral characteristics, as well as the response to treatment were analysed. The subtypes of HIV-1 were evaluated by phylogenetic analysis of protease genes and reverse transcriptase. RESULTS: We identified 141 new diagnoses of HIV infection, the percentage of immigrant origin in P1 was (22.5%), P2 (50%) and P3 (68%). The origin had changed from Latin America in P1 to sub-Saharan Africa in P3. There were no differences between Spanish and immigrant children in the age at diagnosis, the CDC clinical stage A/B/C, viral load, percentage of CD4 at diagnosis and actual. Better viral response was more likely in immigrants after the first regimen of HAART (Highly active antiretroviral treatment) independently of the treatment received. A total of 66 subtypes were obtained, 24% were subtypes non-B (56% recombinants forms). All subtypes of Spanish children (43) and Latin American (5) were subtypes B, and all the children from sub-Saharan Africa (14) were subtypes non-B. CONCLUSION: There were no differences between immigrants and Spanish children infected by HIV, except the different subtypes of HIV-1.

RESUMEN

BACKGROUND: Chagas disease (CD) has become an emerging global health problem in association with the immigration of individuals from endemic areas (in LatinAmerica) to other countries.Spain is the country in Europe with the highest number of CD cases. Concerning pediatric CD, treatment is not only better tolerated by younger children but also has greater cure possibilities. The aim of this study was to describe clinical and epidemiological aspects of CD in a pediatric population diagnosed of 10 hospitals in the Community of Madrid during the 2004-2018 period, as well as the safety and efficacy of CD treatment on this population. METHODOLOGY/PRINCIPAL FINDINGS: A multicenter, retrospective, descriptive study was conducted. The studied population included all identified children under the age of 18 with a diagnosis of CD. Diagnosis was performed with a positive parasitological test (with subsequent confirmation) or confirmed persistence of positive serology beyond 9 months, for children younger than one year-old, and with two different positive serological tests, for children older than one. Fifty-one children were included (59% male; 50.9% born in Spain). All mothers were from Latin America. The median age at diagnosis was 0.7 months for those under one year of age, and 11.08 years for those older than one year-old. Only one case presented a symptomatic course (hydrops faetalis, haemodynamic instability at birth, ascites, anaemia). For 94% treatment was completed. Considering patients who received benznidazole (47), AE were recorded in 48,9%. Among the 32 patients older than one year-old treated with benznidazole, 18 (56.25%) had adverse events whereas in the 15 under one year, 5(33,3%) did. Eigtheen (78.2%) of the patients with benznidazole AE were older than one year-old(median age 11.4 years). Of the patients treated with nifurtimox (9), AE were reported in 3 cases (33,3%). Cure was confirmed in 80% of the children under one year-old vs 4.3% in those older (p<0.001). Loss to follow- up occurred in 35.3% of patients. CONCLUSIONS/SIGNIFICANCES: Screening programs of CD since birth allow early diagnosis and treatment, with a significantly higher cure rate in children treated before one year of age, with lower incidence of adverse events. The high proportion of patients lost to follow-up in this vulnerable population is of concern.

RESUMEN

ABSTRACT: Brain atrophy has been observed in perinatally HIV-infected patients (PHIV) despite initiation on combined antiretroviral treatment (cART), but neuroimaging studies are limited. We aimed to evaluate cortical thickness (CT) and subcortical gray matter (GM) volumes of PHIV youths with stable immunovirological situation and with a normal daily performance.A prospective cross-sectional study was conducted. A total of 25 PHIV patients on cART and 25 HIV-negative (HIV-) controls matched by age, sex, level of education, and socioeconomic status underwent a magnetic resonance imaging scan. CAT12 toolbox was used to extract CT values from T1w images using parcellations from Desikan-Killiany atlas (DK40). To measure regional brain volumes, native segmented images were parceled in regions of interest according to the Neuromorphometrics Atlas. Neuropsychological assessment and psychopathological symptoms were documented.Fifty participants were included (60% females, median age 20 years [interquartile range, IQR 19-23], 64% Whites). No differences regarding neuropsychological tests or psychopathological symptoms were found between groups (all P > .05). All participants presented an average performance in the Fluid Intelligence (FI) test (PHIV mean: -0.12, HIV- mean: 0.24), When comparing CT, PHIV-infected patients showed thinner cortices compared with their peers in fusiform gyrus (P = .000, P = .009), lateral-orbitofrontal gyrus (P = .006, P = .0024), and right parsobitalis gyrus (P = .047). Regarding subcortical GM volumes, PHIV patients showed lower right amygdala (P = .014) and left putamen (P = .016) volumes when compared with HIV- controls. Within the PHIV group, higher CD4 count was associated with higher volumes in right putamen (B = 0.00000038, P = .045). Moreover, increased age at cART initiation and lower nadir CD4 count was associated with larger volumes in left accumbens (B = 0.0000046, P = .033; B = -0.00000008, P = .045, respectively).PHIV patients showed thinner cortices of areas in temporal, orbito-frontal and occipital lobes and lower volumes of subcortical GM volumes when compared with the HIV- control group, suggesting cortical and subcortical brain alterations in otherwise neuroasymptomatic patients. Nevertheless, larger and longitudinal studies are required to determine the impact of HIV on brain structure in PHIV patients and to further identify risk and protective factors that could be implicated.

RESUMEN

INTRODUCTION: The aim of the study was twofold: (i)to determine the prevalence of symptoms of depression and anxiety and sleep disturbances in young patients with vertically-transmitted HIV infection compared to uninfected peers, and (ii)to identify sociodemographic, psychosocial and medication-related variables and other clinical risk and protective factors related to psychological symptoms. METHODS: We conducted a cross-sectional study in two groups with independent measures (36 youth with vertically transmitted HIV infection and 39 HIV-negative peers). We used three standardised assessment tools and a sociodemographic/psychosocial questionnaire (STAI, BDI, PSQI and adapted sociodemographic test). We performed univariate and multivariable analyses. RESULTS: The univariate analysis did not find significant differences between groups either in psychosocial factors or in the clinical scores. The multivariable analysis found that the presence of psychological symptoms was strongly associated with sociodemographic factors and past events. CONCLUSIONS: Psychosocial factors and the social environment seemed to correlate more strongly to psychological symptoms than HIV status and to explain better the current psychological state of individuals.

RESUMEN

BACKGROUND: Assessing the role of HIV and non-HIV related factors is essential for a better understanding of the neurocognitive outcomes in perinatally HIV-infected (PHIV+) young people. The aim of our study was to assess cognition and quality of life (QoL) of a PHIV+ cohort of young people and to compare it with a control group. METHODS: Thirty PHIV+ and 30 HIV(-) healthy young adults matched by age, sex and socioeconomic status completed a protocol that included neurocognitive tests, a psychosocial semi-structured interview and a QoL questionnaire (PedsQL). Neurocognitive domain-specific and domain-general (NPZ-5) Z-scores were calculated. CDC AIDS-defining category C or not C (PHIV+/C, PHIV+/noC) was considered to evaluate differences within the PHIV+ group. Univariate and multivariate analysis were performed. RESULTS: Sixty patients were included; 67% were female; median age (IQR) 19 years (18-21). Regarding PHIV+ young people, 27% showed CDC C category (none encephalopathy), 93% were on ART and 77% had undetectable viral load. No differences regarding occupation were found, although the HIV(-) group repeated less grades (p=0.028) and had a higher education level (p=0.021). No differences were found between PHIV+/noC and HIV(-) participants. However, the PHIV+/C group showed poorer performance than PHIV+/noC (NPZ-5, p=0.037) and HIV(-) subjects (crystallised intelligence, p=0.025; intelligence quotient, p=0.016). Higher nadir CD4+ T-cell count was related to better Z-score in memory (p=0.007) and NPZ-5 (p=0.025). Earlier and longer exposure to ART resulted in better performance in memory (p=0.004) and executive functions (p=0.015), respectively. CONCLUSIONS: No significant differences were found in the neurocognitive profile nor QoL between PHIV+/noC and HIV(-) adolescents; however, PHIV+/C participants obtained lower scores. The use of longer and earlier ART seems to have a beneficial effect.

RESUMEN

Data for a total of 57 patients vertically coinfected with human immunodeficiency virus (HIV)/hepatitis C virus (HCV) and 365 HIV-monoinfected patients were compared until their transition to adult care. No differences regarding the dynamics of CD4 and/or CD8 T-cell counts during childhood were found. The coexistence of HCV does not increase the risk of disease progression in vertically HIV-infected patients.

RESUMEN

BACKGROUND: Chagas disease (CD) is an emergent disease in Europe, due to immigration. The aims of this study are to describe the epidemiological characteristics of a cohort of Chagas infected pregnant women in Spain, to assess the vertical transmission (VT) rate and evaluate the usefulness of the PCR in the diagnosis of congenital infection in the first months of life. METHODS: A descriptive, retrospective study including Chagas seropositive pregnant women who were attended at three tertiary hospitals in Madrid, from January 2012 to September 2016. Infants were examined by PCR at birth and 1 month later and serologically studied at 9 months or later. Children were considered infected when the parasite was detected by PCR at any age or when serology remained positive without decline over the age of 9 months. RESULTS: We included 122 seropositive-infected pregnant women, 81% were from Bolivia and only 8.2% had been treated before. 125 newborns were studied and finally 109 were included (12.8% lost the follow-up before performing the last serology). The VT rate was 2.75% (95% CI: 0,57-8,8%). Infected infants had positive PCR at birth and 1 month later. All of them were treated successfully with benznidazole (PCR and serology became negative later on). All non-infected children presented negative PCR. The mean age at which uninfected patients had negative serology was 10.5 months. CONCLUSIONS: The VT rate is in keeping with literature and confirms the need to carry out a screening in pregnant women coming from endemic areas. PCR seems to be a useful tool to provide early diagnosis of congenital CD.

RESUMEN

BACKGROUND: There are not enough nationwide studies on perinatal HIV transmission in connection with a combination of antiretroviral treatments in Spain. Our objectives were to study sociodemographic changes and trends in the rates of HIV diagnoses and perinatal transmission in Spain from 1997 to 2015. METHODS: A retrospective study using data from Spanish Paediatric HIV Network (CoRISpe) and Spanish Minimum Basic Data Set (MDBS) was performed. HIV- diagnosed children between 1997 and 2015 were selected. Sociodemographic, clinical and immunovirological data of HIV-infected children and their mothers were studied in four calendar periods (P1: 1997-2000; P2: 2001-2005; P3: 2006-2010; P4: 2011-2015). Rates of perinatal HIV diagnoses and transmission from 1997 to 2015 were calculated. RESULTS: A total of 532 HIV-infected children were included in this study. Of these children, 406 were Spanish (76.3%) and 126 immigrants (23.7%). A decrease in the number of HIV diagnoses, 203 (38.2%) children in the first (P1), 149 (28%) in the second (P2), 130 (24.4%) in the third (P3) and 50 (9.4%) in the fourth (P4) calendar periods was studied. The same decrease in the Spanish HIV-infected children (P1, 174 (46.6%), P2, 115 (30.8%), P3, 65 (17.4%) and P4, 19 (5.1%)) was monitored. However, an increase in the number of HIV diagnoses by sexual contact (P1: 0%; P2: 1.3%; P3: 4.6%; P4: 16%) was observed. The rates of new perinatal HIV diagnoses and perinatal transmission in Spanish children decreased from 0.167 to 0.005 per 100,000 inhabitants and 11.4% to 0.4% between 1997 and 2015, respectively. CONCLUSIONS: A decline of perinatal HIV diagnoses and transmission was observed. However, an increase of teen-agers HIV diagnoses with sexual infection was studied. Public awareness campaigns directed to teen-agers are advisable to prevent HIV infection by sexual contact.

RESUMEN

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 CMV (cCMV) infection. MATERIALS AND METHODS: A retrospective observational study was conducted in three tertiary hospitals in Madrid. In the period 2009-2015, CMV-HIG (Cytotect® CP Biotest, Biotest) treatment was offered to all pregnant women with primary CMV infection and/or detection of CMV-DNA in amniotic fluid in participating centers. Women were divided into prevention and treatment groups (PG and TG, respectively). Those with primary CMV infection who had not undergone amniocentesis comprised the PG and received monthly CMV-HIG (100 UI/kg). If CMV-DNA was subsequently detected in amniotic fluid, one extra dose of CMV-HIG (200 UI/kg) was given 4 weeks after the last dose. Those women were considered to be part of the PG group despite detection of CMV-DNA in amniotic fluid. In the case of a negative result in CMV-DNA detection in amniotic fluid or if amniocentesis was not performed, monthly HIG was given up to the end of the pregnancy. RESULTS: Thirty-six pregnant women were included. Median gestational age at birth was 39 weeks (interquartile range: 38-40) and two children (5.5%) were premature (born at 28 and 34 weeks' gestation). Amniocentesis was performed in 30/36 (83.4%) pregnancies and CMV PCR was positive in 21 of them (70%). One fetus with a positive PCR in amniotic fluid that received one dose of HIG after amniocentesis presented a negative CMV-PCR in urine at birth, and was asymptomatic at 12 months of age. Twenty-four children were infected at birth, and 16/21 (76.2%) presented no sequelae at 12 months, while two (9.5%) had a mild unilateral hearing loss and three (14.3%) severe hearing loss or neurological sequelae. Seventeen women were included in the PG and 19 in the TG. In the PG 7/17 (41%) fetuses were infected, one pregnancy was terminated due to abnormalities in cordocentesis and one showed a mild hearing loss at 12 months of age. In the TG, 18/19 children (95%) were diagnosed with cCMV, while the remaining neonate had negative urine CMV at birth. Eight out of the 19 fetuses (42.1%) showed CMV related abnormalities in the fetal US before HIG treatment. Complete clinical assessment in the neonatal period and at 12 months of age was available in 16 and 15 children, respectively. At birth 50% were symptomatic and at 12 months of age, 4/15 (26.7%) showed a hearing loss and 3/15 (20%) neurologic impairment. Fetuses with abnormalities in ultrasonography before HIG presented a high risk of sequelae (odds ratios: 60; 95%CI: 3-1185; p = .007). DISCUSSION: Prophylactic HIG administration in pregnant women after CMV primary infection seems not to reduce significantly the rate of congenital infection, but is safe and it could have a favorable effect on the symptoms and sequelae of infected fetuses. The risk of long-term sequelae in fetuses without US abnormalities before HIG is low, so it could be an option in infected fetuses with normal imaging. On the other hand, the risk of sequelae among infected fetuses with abnormalities in fetal ultrasonography before HIG despite treatment is high.

RESUMEN

BACKGROUND: Studies investigating health-related quality of life (HRQoL) in youth with perinatally acquired HIV (PHIV+) are scarce. This study aimed to compare HRQoL of PHIV+ to sociodemographic-matched youth not living with HIV (HIV-), Spanish general youth population, and to explore associations between sociodemographic variables, drug consumption, and HRQoL. METHODS: PHIV+ youth were randomly selected from CoRISpe database (Cohort of the Spanish Pediatric HIV Network). HRQoL was evaluated by SF-12v2. RESULTS: Thirty-nine PHIV+ youth (mean age: 23.36 years, SD = 3.83) and thirty-nine HIV- youth (mean age: 22.97 years, SD = 3.80) participated in this study. PHIV+ obtained lower scores in SF-12 physical health subscale (PCS) than HIV- (P = 0.001) and Spanish general youth population (P = 0.006). PHIV+ had lower scores on the mental health subscale (MCS) than the Spanish general youth population (P < 0.001). PHIV+ who were at school obtained better scores than those were not at school. PHIV+ youth who had used cocaine and cannabis had lower scores in MCS (P = 0.002). CONCLUSIONS: There is a need for HRQoL management in the associated medical follow-up.

RESUMEN

BACKGROUND: Combination antiretroviral therapy (cART) is associated with marked immune reconstitution. Although a long term viral suppression is achievable, not all children however, attain complete immunological recovery due to persistent immune activation. We use CD4/CD8 ratio like a marker of immune reconstitution. METHODS: Perinatal HIV-infected children who underwent a first-line cART, achieved viral suppression in the first year and maintained it for more than 5 years, with no viral rebound were included. Logistic models were applied to estimate the prognostic factors, clinical characteristics at cART start, of a lower CD4/CD8 ratio at the last visit. RESULTS: 146 HIV-infected children were included: 77% Caucasian, 45% male and 28% CDC C. Median age at cART initiation was 2.3 years (IQR: 0.5-6.2). 42 (30%) children received mono-dual therapy previously to cART. Time of undetectable viral load was 9.5 years (IQR: 7.8, 12.5). 33% of the children not achieved CD4/CD8 ratio >1. Univariate analysis showed an association between CD4/CD8 <1 with lower CD4 nadir and baseline CD4; older age at diagnosis and at cART initiation; and a previous exposure to mono-dual therapy. Multivariate analysis also revealed relationship between CD4/CD8 <1 and lower CD4 nadir (OR: 1.002, CI 95% 1.000-1.004) as well as previous exposure to mono-dual therapy (OR: 0.16, CI 95% 0.003-0.720). CONCLUSIONS: CD4/CD8 >1 was not achieved in 33% of the children. Lower CD4 nadir and previous exposure to suboptimal therapy, before initiating cART, are factors showing independently association with a worse immune recovery (CD4/CD8 < 1).

RESUMEN

BACKGROUND: Novel antiretroviral formulations that are palatable, safe, and effective are needed for infants and children. METHODS: PRINCE-2 is an ongoing clinical trial assessing safety, efficacy, and palatability of once-daily atazanavir powder formulation boosted with ritonavir (ATV + RTV) plus optimized dual nucleos(t)ide reverse transcriptase inhibitors therapy in antiretroviral-naïve/experienced children with screening HIV-1 RNA ≥1000 copies/mL. Children 3 months to <11 years received ATV + RTV by 5 baseline weight bands: 5 to <10 kg = 150/80 mg; 5 to <10 kg = 200/80 mg; 10 to <15 kg = 200/80 mg; 15 to <25 kg = 250/80 mg; and 25 to <35 kg = 300/100 mg. RESULTS: Of 99 treated children, 83.8% and 59.6% remained on ATV powder until 24 and 48 weeks, respectively. Through 48 weeks, the most common adverse events were upper respiratory tract infections (33.3%), gastroenteritis (28.3%), vomiting (21.2%) and hyperbilirubinemia (18.2%; none leading to treatment discontinuation). Serious adverse events occurred in 20.2% of patients. Laboratory grade 3-4 hyperbilirubinemia occurred in 9.2% and elevated total/pancreatic amylase in 33.7%/3.1%. At week 24, proportions with virologic suppression (HIV-1 RNA <50 copies/mL; intention-to-treat analysis) across weight bands were 10/23 (43.5%), 2/12 (16.5%), 10/21 (47.6%), 19/35 (54.3%) and 5/8 (62.5%), respectively. Virologic suppression was similar in antiretroviral-naïve/experienced patients and lowest in the 5 to <10 kg = 200/80 mg group, likely because of higher baseline HIV-1 RNA and discontinuation (66.7%). Overall, virologic suppression at weeks 24 (46.5%) and 48 (43.0%) was comparable. At week 48, 83.3% and 74.1% of caregivers reported no trouble giving ATV powder and RTV, respectively. CONCLUSIONS: ATV powder palatability, efficacy and lack of unexpected safety findings support its use for HIV-1-infected children ≥3 months to <11 years.
