RESUMO
BACKGROUND: Respiratory syncytial virus (RSV) is a common cause of lower respiratory tract infections in infants. This phase 1/2, observer-blind, randomized, controlled study assessed the safety and immunogenicity of an investigational chimpanzee-derived adenoviral vector RSV vaccine (ChAd155-RSV, expressing RSV F, N, and M2-1) in infants. METHODS: Healthy 6- to 7-month-olds were 1:1:1-randomized to receive 1 low ChAd155-RSV dose (1.5 × 1010 viral particles) followed by placebo (RSV_1D); 2 high ChAd155-RSV doses (5 × 1010 viral particles) (RSV_2D); or active comparator vaccines/placebo (comparator) on days 1 and 31. Follow-up lasted approximately 2 years. RESULTS: Two hundred one infants were vaccinated (RSV_1D: 65; RSV_2D: 71; comparator: 65); 159 were RSV-seronaive at baseline. Most solicited and unsolicited adverse events after ChAd155-RSV occurred at similar or lower rates than after active comparators. In infants who developed RSV infection, there was no evidence of vaccine-associated enhanced respiratory disease (VAERD). RSV-A neutralizing titers and RSV F-binding antibody concentrations were higher post-ChAd155-RSV than postcomparator at days 31, 61, and end of RSV season 1 (mean follow-up, 7 months). High-dose ChAd155-RSV induced stronger responses than low-dose, with further increases post-dose 2. CONCLUSIONS: ChAd155-RSV administered to 6- to 7-month-olds had a reactogenicity/safety profile like other childhood vaccines, showed no evidence of VAERD, and induced a humoral immune response.

The number of people with immunosuppression is increasing considerably due to their greater survival and the use of new immunosuppressive treatments for various chronic diseases. This is a heterogeneous group of patients in whom vaccination as a preventive measure is one of the basic pillars of their wellbeing, given their increased risk of contracting infections. This consensus, developed jointly by the Sociedad Española de Infectología Pediátrica (Spanish Society of Pediatric Infectious Diseases) and the Advisory Committee on Vaccines of the Asociación Española de Pediatría (Spanish Association of Paediatrics), provides guidelines for the development of a personalised vaccination schedule for patients in special situations, including general recommendations and specific recommendations for vaccination of bone marrow and solid organ transplant recipients, children with inborn errors of immunity, oncologic patients, patients with chronic or systemic diseases and immunosuppressed travellers.

Background: Integrase inhibitor (INSTI) with boosted darunavir (DRV/r), a regimen with a high-resistance barrier, avoiding NRTI toxicities, might be a switching option in children living with HIV (CLWHIV). Methods: SMILE is a randomised non-inferiority trial evaluating safety and antiviral efficacy of once-daily INSTI + DRV/r vs. continuing on current standard-of-care (SOC) triple ART (2NRTI + boosted PI/NNRTI) in virologically-suppressed CLWHIV aged 6-18 years. The primary outcome is the proportion with confirmed HIV-RNA ≥50 copies/mL by week 48, estimated by Kaplan-Meier method. Non-inferiority margin was 10%. Registration number for SMILE are: ISRCTN11193709, NCT #: NCT02383108. Findings: Between 10th June 2016 and 30th August 2019, 318 participants were enrolled from Africa 53%, Europe 24%, Thailand 15% and Latin America 8%, 158 INSTI + DRV/r [153 Dolutegravir (DTG); 5 Elvitegravir (EVG)], 160 SOC. Median (range) age was 14.7 years (7.6-18.0); CD4 count 782 cells/mm3 (227-1647); 61% female. Median follow-up was 64.3 weeks with no loss to follow-up. By 48 weeks, 8 INSTI + DRV/r vs. 12 SOC had confirmed HIV-RNA ≥50 copies/mL; difference (INSTI + DRV/r-SOC) -2.5% (95% CI: -7.6, 2.5%), showing non-inferiority. No major PI or INSTI resistance mutations were observed. There were no differences in safety between arms. By week 48, difference (INSTI + DRV/r-SOC) in mean CD4 count change from baseline was -48.3 cells/mm3 (95% CI: -93.4, -3.2; p = 0.036). Difference (INSTI + DRV/r-SOC) in mean HDL change from baseline was -4.1 mg/dL (95% CI: -6.7, -1.4; p = 0.003). Weight and Body Mass Index (BMI) increased more in INSTI + DRV/r than SOC [difference: 1.97 kg (95% CI: 1.1, 2.9; p < 0.001), 0.66 kg/m2 (95% CI: 0.3, 1.0; p < 0.001)]. Interpretation: In virologically-suppressed children, switching to INSTI + DRV/r was non-inferior virologically, with similar safety profile, to continuing SOC. Small but significant differences in CD4, HDL-cholesterol, weight and BMI were observed between INSTI + DRV/r vs. SOC although clinical relevance needs further investigation. SMILE data corroborate adult findings and provide evidence for this NRTI-sparing regimen for children and adolescents. Funding: Fondazione Penta Onlus, Gilead, Janssen, INSERM/ANRS and UK MRC.

Introducción. La mayoría de infecciones por SARS-CoV2 en población pediátrica cursan asintomáticas o con síntomas leves, con porcentaje mínimo de casos graves descritos como síndrome inflamatorio multisistémico asociado al SARS-CoV2 (SIM-PEDs). El objetivo fue describir las características clínico-epidemiológicas de aquellos pacientes pediátricos ingresados con diagnóstico confirmado de SARS-CoV2, y las posibles diferencias de la enfermedad considerando dos períodos epidemiológicos. Material y métodos. Estudio retrospectivo observacional de pacientes pediátricos ingresados con diagnóstico de COVID-19, de un hospital terciario. Se recogieron de forma consecutiva, entre marzo de 2020 hasta febrero 2022, analizando datos demográficos, clínicos, pruebas complementarias, tratamiento administrado y evolución. Resultados. Se incluyeron 69 pacientes, clasificándose en 6 grupos según diagnóstico. Los pacientes con neumonía asociaban mayor hipoxemia, mayor edad y eran predominantemente varones (p<0.01), con respecto al grupo de infecciones respiratorias sin condensación. SIM-PEDs fueron pacientes más graves, con afectación analítica marcada y mayor ingreso en UCIP. Durante el 2º periodo se observa una tendencia a la disminución de la infección respiratoria (69% al 47%), menor estancia hospitalaria (de 4 a 3 días), y aumento de los ingresos por otra patología (7,7% al 30,6%). Conclusiones. Los cuadros clínicos de COVID-19 más frecuentes en niños son respiratorios leves-moderados con buena evolución. Hay una tendencia a menor duración de estancia hospitalaria y aumento de ingresos por otra patología en pacientes asintomáticos en el segundo periodo. SIM-PEDs es otra forma de expresión de infección por SARS-COV2 de mayor gravedad, pero habitualmente con buen pronóstico tras diagnóstico precoz y requiriendo frecuentemente ingreso en UCIP.

Introduction. Most SARS-CoV2 infections in pediatric population are asymptomatic or have mild symptoms, with a small percentage of severe cases described as SARS-CoV2-associated multisystem inflammatory syndrome (MIS-C). The objective was to describe the clinical-epidemiological characteristics of those pediatric patients admitted with a SARS-CoV2 confirmed diagnosis, and the possible differences in the disease considering two epidemiological periods. Methods. Observational retrospective study of pediatric patients admitted with a diagnosis of COVID-19, from a tertiary hospital. They were collected consecutively, between March 2020 and February 2022, analyzing demographic and clinical data, complementary tests, administered treatment and evolution. Results. 69 patients were included, classified into 6 groups according to diagnosis. Patients with pneumonia associated greater hypoxemia, older age and were predominantly male (p<0.01), with respect to the group of respiratory infections without condensation. MIS-C were more severe patients, with marked analytic involvement and greater admission to the PICU. During the 2nd period, there was a trend towards a decrease in respiratory infection (69% to 47%), a shorter hospital stays (4 to 3 days), and an increase in admissions for another pathology (7.7% to 30,6%). Discussion. The most frequent clinical manifestations of COVID-19 in children are mild-moderate respiratory symptoms with a good prognosis. There is a trend towards a shorter length of hospital stay and an increase in admissions for another pathology in asymptomatic patients in the second period. MIS-C is another form of expression of SARS-COV2 infection of greater severity, but usually with a good prognosis after early diagnosis and frequently requiring PICU admission.

RESUMO
In 2010, the WHO recommended an increase in the daily doses of first-line anti-tuberculosis medicines in children. We aim to characterize the pharmacokinetics of the once-daily isoniazid (INH) dose at 10 mg/kg of body weight in infants <6 months of age. We performed a multicenter pharmacokinetic study in Spain. The N-acetyltransferase 2 gene was analyzed to determine the acetylation status. Samples were analyzed using a validated UPLC-UV assay. A non-compartmental pharmacokinetic analysis was performed. Twenty-three pharmacokinetic profiles were performed in 20 infants (8 females) at a median (IQR) age of 19.0 (12.6-23.3) weeks. The acetylator statuses were homozygous fast (n = 1), heterozygous intermediate (n = 12), and homozygous slow (n = 7). INH median (IQR) Cmax and AUC0-24h values were 4.8 (3.7-6.7) mg/L and 23.5 (13.4-36.7) h*mg/L and the adult targets (>3 mg/L and 11.6-26.3 h*mg/L) were not reached in three and five cases, respectively. The age at assessment or acetylator status had no impact on Cmax values, but a larger INH AUC0-24h (p = 0.025) and trends towards a longer half-life (p = 0.055) and slower clearance (p = 0.070) were observed in homozygous slow acetylators. Treatment was well tolerated; mildly elevated alanine aminotransferase levels were observed in three cases. In our series of young infants receiving isoniazid, no major safety concerns were raised, and the target adult levels were reached in most patients.
RESUMO
BACKGROUND: Children and adolescents living with HIV (CALHIV) are at high risk of meningococcal infections and may present lower immune responses to vaccines. The objectives of this study were to assess the immunogenicity of the quadrivalent Men ACWY-TT vaccine (Nimenrix®) in CALHIV after a two-dose schedule and to describe possible HIV-related factors that may affect the immunogenic response. METHODS: A multicenter prospective study was designed, including CALHIV followed in five hospitals in Madrid, between 2019 and 2021. Two doses of the Men ACWY-TT vaccine were administered. Serum bactericidal antibody (SBA) assays using rabbit complement (rSBA) against serogroups C, W, and Y were used to determine seroprotection and vaccine response (the proportion achieving a putative protective titer of ≥eight or a ≥four-fold rise in titer from baseline). Serum was collected at baseline, and at 3 and 12 months after vaccination. RESULTS: There were 29 CALHIV included, 76% of whom were perinatally infected. All were receiving TAR and presented a good immunovirological and clinical status overall. At baseline, 45% of CALHIV had seroprotective titers to at least one serogroup, with individual seroprotection rates of 24%, 28%, and 32% against C, W, and Y, respectively. After a two-dose schedule, vaccine response was 83% for each serogroup, eliciting a vaccine response to all serogroups in 69% of them. One year after vaccination, 75% of CALHIV maintained seroprotective titers against the C serogroup, and 96% against W and Y. None of the HIV-related characteristics analyzed could predict vaccine response or antibody duration. CONCLUSIONS: CALHIV who received effective TAR and presented a good immuno-virological situation achieved an appropriate vaccine response after two doses of the Men ACWY-TT vaccine, and antibody-mediated protection against serogroups C, W, and Y was maintained in more than 70% of the patients one year after vaccination.
RESUMO
INTRODUCTION: Congenital citomegalovirus (CMVc) infection is more common in children exposed to HIV during pregnancy, with reported rates in pre-ART era from 2 to 7%. The use of combined antiretroviral treatment (ARTc) could be a determining factor in reducing this risk of CMV transmission. The aim of this study was to describe the epidemiology of CMVc infection in newborns of HIV-infected mothers at Hospital Universitario 12 de Octubre, Madrid, Spain, from 2000 to 2017. MATERIAL AND METHODS: An observational and retrospective study was carried out. Epidemiological and clinical variables were collected. Statistical analysis was performed with the SPSS 24.0 computer program. RESULTS: 288 mother-infant pairs were included in the study. We observed a CMVc rate of 2.1% (95% CI 0.9-4.9). CONCLUSIONS: The rate of CMVc in HIV-exposed children observed was lower than that reported in pre-ARTc era but seems higher than those described in general population.

BACKGROUND: An increasing number of women living with perinatally acquired HIV are reaching adulthood and becoming pregnant. Achieving viral suppression is challenging in this population frequently exposed to numerous antiretroviral regimens. This study describes the long-term outcomes of pregnant women living with perinatally acquired HIV in Spain. METHODS: Descriptive, retrospective, multicenter study of the women living with perinatally acquired HIV who gave birth between January 2000 and December 2019 in Madrid. Epidemiological, clinical, and HIV-related data were collected from the first delivery to the end of the study period, including antiretroviral therapy, prevention strategies, and outcomes. RESULTS: Sixty-three live births in 33 women were included. The mean number of pregnancies per women was 1.9 (range: 1-6). At first delivery, women's median age was 20 years (interquartile range: 18-23), 11 (33.3%) had been previously diagnosed with AIDS and 6 (18%) with mental health disorders. Forty percent became pregnant unsuppressed, whereas 81% achieved viral suppression at delivery. Treatment interruptions were common after delivery, as were losses to follow-up, with no positive effect of pregnancy on retention to care or the immune virological situation. Five women (15%) experienced a new AIDS event, and there were 2 deaths (6%) during follow-up. There was 1 case of mother-to-child transmission in a nonadherent woman in whom preventive measures could not be implemented. CONCLUSIONS: Pregnancy in this unique population of women living with perinatally acquired HIV poses particular challenges. Specific strategies, including a multidisciplinary approach, are needed to minimize perinatal transmission risks and improve outcomes during the postpartum period.

BACKGROUND: HIV infection continues to be a worldwide public health problem. After the introduction of effective preventive measures, perinatal transmission dramatically decreased. Our aim was to assess the sociodemographic changes in pregnant women living with HIV infection and trends in perinatal transmission rates over time. SETTING: The Madrid cohort of HIV-infected mother-infant pairs is a multicenter, prospective, observational, and cohort study that collects information on HIV-infected pregnant women and their children. METHODS: Information on clinical-epidemiological characteristics of HIV-infected pregnant women until delivery and their children from 9 public hospitals was included. Data were collected from a standardized questionnaire from medical records. The results were classified in 3 periods: period 1 (P1) 2000-2006, period 2 (P2) 2007-2013, and period 3 (P3) 2014-2020. RESULTS: A total of 1521 women living with HIV and 1548 newborns were included. In P1, most mothers (75.8%) were Spanish, whereas in P2 and P3 there was a predominance of foreign origin [62.8% and 70.5% respectively ( P < 0.01)]. The percentage of women with antiretroviral treatment before pregnancy increased significantly in P3 ( P < 0.01). The proportion of Caesarean sections decreased over time ( P < 0.01): 66.2% (n = 472) in P1, 54.9% (n = 245) in P2, and 46.7% (n = 141) in P3. The percentage of preterm and low birth weight newborns showed a statistically significant decrease. Even though there were no statistically significant differences ( P = 0.154), a decrease in cases of perinatal infection was observed (1.6% in P1, 1.3% in P2 and 0.3% in P3). CONCLUSIONS: The epidemiologic characteristics of pregnant women with HIV infection have changed over time in our setting, with an increase of non-Caucasian, heterosexual, and perinatally infected mothers. Although there are still perinatal infections, especially in vulnerable populations such as immigrant women, transmission rate has markedly decreased in recent years and is still of major concern. Prevention measures should be reinforced in the most socially disadvantaged groups.

Multicenter study designed to describe epidemiologic and clinical characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive cases registered among children and adolescents living with HIV (CALWH). SARS-CoV-2 infection was confirmed in 13.3% of CALWH, with all patients presenting mild symptoms, and the outcome was good in all patients. None of the HIV- and antiretroviral treatment-related variables studied were associated with greater infection risk or could be considered protective.

Rotavirus (RV) is the most common cause of severe gastroenteritis (GE) in infants and young children worldwide and is associated with a significant clinical and economic burden. The objective of this study was to analyze the characteristics, healthcare resource utilization and the direct medical costs related to RVGE hospitalizations in Spain. An observational, multicenter, cross-sectional study was conducted from June 2013 to May 2018 at the pediatric departments of 12 hospitals from different Spanish regions. Children under 5 years of age admitted to the hospital with a confirmed diagnosis of RVGE were selected. Data on clinical characteristics, healthcare resource use and costs were collected from patient records and hospital databases. Most children hospitalized for RVGE did not have any previous medical condition or chronic disease. Forty-seven percent had previously visited the Emergency Room (ER), 27% had visited a primary care pediatrician, and 15% had received pharmacological treatment prior to hospital admission due to an RVGE episode. The average length of a hospital stay for RVGE was 5.6 days, and the mean medical costs of RVGE hospitalizations per episode ranged from 3,940 to 4,100. The highest direct medical cost was due to the hospital stay. This study showed a high burden of health resource utilization and costs related to the management of cases of RVGE requiring hospitalization. RV vaccination with high coverage rates should be considered to minimize the clinical and economic impacts of this disease on the health-care system.

INTRODUCTION: The aim of the study was twofold: a) 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 b) 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 3 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.

Introduction: Most SARS-CoV2 infections in the pediatric population are asymptomatic or with mild symptoms, with a minimal proportion of severe cases described as SARS-CoV2-associated multi-system inflammatory syndrome (MIS-C).The objective was to describe the clinical and epidemiological characteristics of pediatric patients admitted with confirmed diagnosis of SARS-CoV2 infection from the beginning of the pandemic until May 2021. Methods: Retrospective observational study of pediatric patients hospitalized with confirmed COVID-19, in a tertiary hospital. Epidemiological and clinical data, additional tests, treatments administered and evolution were collected. Results: 30 patients were included, classified into 3 groups according to diagnosis: respiratory infection, MIS-C and compatible symptoms. The patients with pneumonia were associated with age older, comorbidities and lymphopenia. MIS-C were more serious patients, with marked laboratory involvement and greater admission to PICU. Most of these were secondary cases of contact in the family environment. Discussion: The most frequent clinical manifestations of COVID-19 in children are mild-moderate respiratory with good evolution. MIS-C is another form of expression of SARS-COV2 infection of greater severity, but usually with good prognosis after early diagnosis and frequent PICU admission.

RESUMO
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.

OBJECTIVE: To investigate the optic nerve and macular parameters of children who recovered from COVID-19 compared with healthy children using optical coherence tomography (OCT). DESIGN: Cohort study. SETTING: Hospital Clinico San Carlos, Madrid. PATIENTS: Children between 6 and 18 years old who recovered from COVID-19 with laboratory-confirmed SARS-CoV-2 infection and historical controls were included. INTERVENTIONS: All patients underwent an ophthalmological examination, including macular and optic nerve OCT. Demographic data, medical history and COVID-19 symptoms were noted. MAIN OUTCOME MEASURES: Peripapillary retinal nerve fibre layer thickness, macular retinal nerve fibre layer thickness, macular ganglion cell layer thickness and retinal thickness. RESULTS: 90 patients were included: 29 children who recovered from COVID-19 and 61 controls. Patients with COVID-19 presented an increase in global peripapillary retinal nerve fibre layer thickness (mean difference 7.7; 95% CI 3.4 to 12.1), temporal superior (mean difference 11.0; 95% CI 3.3 to 18.6), temporal inferior (mean difference 15.6; 95% CI 6.5 to 24.7) and nasal (mean difference 9.8; 95% CI 2.9 to 16.7) sectors. Macular retinal nerve fibre layer analysis showed decreased thickness in the nasal outer (p=0.011) and temporal inner (p=0.036) sectors in patients with COVID-19, while macular ganglion cell layer thickness increased in these sectors (p=0.001 and p=0.015, respectively). No differences in retinal thickness were noted. CONCLUSIONS: Children with recent history of COVID-19 present significant changes in peripapillary and macular OCT analyses.

BACKGROUND: Perinatal transmission of HIV has dramatically decreased in high-income countries in the last few years with current rates below 1%, but it still occurs in high-risk situations, mainly pregnant women with late diagnosis of infection, poor antiretroviral adherence and a high viral load (VL). In these high-risk situations, many providers recommend combined neonatal prophylaxis (CNP). Our aim was to evaluate the safety and toxicity of CNP in infants deemed at high-risk of HIV infection among mother-infant pairs in the Madrid Cohort. MATERIALS AND METHODS: Prospective, multicenter, observational cohort study between years 2000 and 2019. The subgroup of newborns on CNP and their mothers were retrospectively selected (cohort A) and compared with those who received monotherapy with zidovudine (cohort B). Infants with monotherapy were classified according to treatment regimes in long (6 weeks) and short (4 weeks) course. RESULTS: We identified 227 newborns (33.3% preterm and 7 sets of twins) with CNP. A maternal diagnosis of HIV-1 infection was established during the current pregnancy in 72 cases (36.4%) and intrapartum or postpartum in 31 cases (15.7%). Most infants received triple combination antiretroviral therapy (65.6%; n = 149). The perinatal transmission rate in cohort A was 3.5% (95% confidence interval: 1.13%-5.92%). Infants from cohort A developed anemia (26.1% vs. 19.4%, P = 0.14) and neutropenia more frequently at 50-120 days (21.4% vs. 10.9%, P < 0.01), without significant differences in grade 3 and 4 anemia or neutropenia between the two cohorts. There were no differences in increased alanine aminotransferase. Neutropenia was more common in the long zidovudine regimes. CONCLUSIONS: Our findings provide further evidence of the safety of CNP in infants with high-risk of HIV-1 perinatal transmission.
