Introduction: The vertical transmission rate (VTR) of HIV has decreased to less than 2% in high-income countries, in spite of which perinatal infections continue to occur. We present data from the national cohort of pregnant women living with HIV and their children in Spain. The objectives were to describe the characteristics of this population, evaluate the VTR of HIV, the safety of antiretroviral therapy (ART) and the prevalence of coinfection., Patients and Methods: Multicentre prospective, observational and descriptive study with participation of 62 hospitals. The sample included pegnant women living with HIV whose children were born between January 2020 and December 2022. We collected prospective data on the characteristics of mothers and children using an online questionnaire (REDCap web application)., Results: The study included 414 mother-child dyads. Most mothers were immigrants (227/349; 65.1%). The main route of HIV infection was heterosexual transmission (160/402; 39.8%), followed by vertical transmission (44/402; 10.9%). The diagnosis was made before conception in 313/389 women (80.4%), 394/402 (98%) received ART during pregnancy and 356/402 (89.3%) had an undetectable viral load at the time of delivery. The delivery was vaginal in 230/388 children (59.3%). The proportion of preterm birth was 11.1%. The most frequent neonatal prophylaxis approach was monotherapy with zidovudine (358/414; 86.5%). There were 3 cases of vertical transmission of HIV (95% CI, 0%-1.54%). Only one newborn was breastfed., Conclusions: At present, most women living with HIV in Spain receive the diagnosis before conception, are of foreign ancestry and achieve good control of the infection. Although the VTR is very low in Spain, there are still infections that could be prevented with early diagnosis and treatment., (Copyright © 2024 Asociación Española de Pediatría.

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., (Copyright © 2023 Asociación Española de Pediatría.

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., (Copyright © 2022 Asociación Española de Pediatría.

Objectives: To evaluate the psychosocial status of the patients who attend a paediatric endocrinology clinic due to gender incongruity (GI), and to establish the impact on this after one-year of cross hormonal therapy (CHT)., Material and Methods: An analytical and prospective study conducted on adolescents between 14 and 18 years old with GI, and who attended the Endocrinology clinic during 2018-2019. The sample included 23 transgender cases (16 male and 7 female cases) and 30 cisgender controls. Study variables were collected at T0 (pre-treatment) and T1 (after one year of CHT) and included sociodemographic data, Utrecht test, SDQ-Cas test, family APGAR test, STAI scale-anxiety Grade, and BDI-II depression assessment test., Results: A significant improvement (P<.05) was found between T0 and T1 in the transgender group in terms of emotional symptoms, behaviour problems, hyperactivity symptoms, pro-social conduct, as well as in the degree of anxiety and depression measured by the SDQ-Cas test, the STAI and the BDI-II scale. There were significant differences in these scales between the transgender group and the controls at T0, however, the scores equalised at T1. The families in this sample of transgender patients provided a very favourable environment according to the scores obtained on the family APGAR scale., Conclusions: The rates of anxiety, emotional and behaviour distress, depressive symptomatology, as well as the feeling of gender dysphoria of these transgender patients were similar to those of non-transsexual population of the same age after one year of CHT initiated at ages between 14-18 years old., (Copyright © 2020.

Introduction: There are only a limited number of studies on the impact of influenza in the Spanish child population. The present work intends to increase this knowledge by studying some key aspects, such as the incidence of hospital admissions, clinic variables, comorbidities, and the vaccination status in the hospitalised children., Methods: A retrospective, observational study was conducted by reviewing the medical records of children under 15 years and hospitalised due to community acquired influenza confirmed microbiologically, during 2́flu seasons (2014-2015 and 2015-2016). The study was carried out in 10 hospitals of 6cities, which represent approximately 12% of the Spanish child population., Results: A total of 907 children were admitted to hospital with main diagnosis of influenza infection (447 <2 years), estimating an average annual rate of hospitalisation incidence of 0.51 cases / 1,000 children (95% CI; 0.48-0.55). Just under half (45%) of the cases had an underlying disease considered a risk factor for severe influenza, and most (74%) had not been vaccinated. The percentage of children with underlying diseases increased with age, from 26% in children <6 months to 74% in children >10 years. Admission to the PICU was required in 10% (92) of the cases, mainly due to acute respiratory failure., Conclusion: Influenza continues to be an important cause of hospitalisation in the Spanish child population. Children <6 months of age and children with underlying diseases make up the majority (> 50%) of the cases. Many of the severe forms of childhood influenza that occur today could be avoided if current vaccination guidelines were met., (Copyright © 2018 Asociación Española de Pediatría.

Background: Chagas disease, caused by Trypanosoma cruzi (T. cruzi), is endemic in Latin-America and is emerging in Spain due to immigration. The vertical transmission rate is around 5%. A routine prenatal screening with serology of all pregnant women from endemic areas is recommended to identify infected newborns, allowing early treatment and cure., Objective: The aim of this study was to estimate the prevalence of positive Chagas serology in a cohort of pregnant women from Latin-America and its vertical transmission., Patients and Methods: An observational, prospective, follow-up study was conducted on women with positive serology to T. cruzi, as well as their newborns, from January 2013 to April 2015. Congenital Chagas was ruled out using a PCR technique at birth and at 1 month, and with serology at 9-12 months old. A child was considered infected when PCR was positive, and uninfected when PCR was negative, and/or it had a negative serology., Results: Screening was performed on 1244 pregnant women from Latin-America, and there were positive results in 40 (prevalence 3.2%, 95% CI: 2.4-4.4%), with 85% of them from Bolivia. There was only one infected newborn (rate of vertical transmission 2.8% (95% CI: 0-15%)), who had a positive PCR at birth. Relative studies enabled an 8-year-old sister with an asymptomatic disease to be diagnosed and treated. Both were treated successfully with benznidazole (later the PCR and serology were negative)., Conclusion: Screening during pregnancy in Latin-American women helped to detect those with Chagas disease. The rate of vertical transmission was 2.8%, in keeping with literature. Screening led to the detection and treatment of previously unidentified familial cases., (Copyright © 2016 Asociación Española de Pediatría. Publicado por Elsevier España, S.L.U.

Tuberculosis (TB) is the most important infectious disease all over the world, with a high morbidity and mortality. Pediatric tuberculosis has been a neglected epidemic, due to the difficulties in assessing its global impact, reduced incidence and lower infectivity compared to adults. In 2015, the WHO reported 1 million cases of paediatric TB and 169,000 deaths. In Europe, the emergence of MDR TB is a major concern, representing 16% of the new diagnosis in Eastern Europe. In 2014, it was estimated that about 219,000 children were infected by MDR-TB-strains in Europe, and 2,120 developed the disease. Spain is the Western European country with more paediatric cases, with an incidence 4.3/100,000 inhabitants in 2014. Paediatric tuberculosis mortality in Spain is rare, but extra-pulmonary disease is associated with significant complications. The prevalence of paediatric drug resistant TB in Spain is over 4%, higher than the estimated incidence in adult population, representing mayor difficulties for therapeutic intervention. These data reveal that paediatric TB is still a Public Health priority in our country. The difficulties in diagnosis and the lack of optimal paediatric drug formulations are the major challenges for controlling the childhood's tuberculosis epidemic. A group of national paeditric TB experts has reviewed the international guidelines and the most recent evidences, and has established new recommendations for the management of paediatric TB contacts, latent infection and active TB disease, especially focused in drug resistant cases. This document replaces the former national guidelines from the Spanish Society for Pediatric Infectios Diseases, although the prior recommendations on the diagnosis remain valid., (Copyright © 2017 Asociación Española de Pediatría.
