RESUMEN
Globalisation and population movement have led to an increasing number of migrant children residing in areas non-endemic for schistosomiasis. However, diagnosing and managing schistosomiasis in children remain controversial. This study aims to investigate the prevalence of schistosomiasis in migrant children and to describe the diagnostic approach and management strategies, including long-term follow-up, to explore the potential role of serological tests in evaluating treatment response. We conducted a retrospective descriptive study spanning from January 2014-July 2021 at a referral unit for Paediatric Tropical Diseases in Madrid (Spain). The study included patients under 18 years diagnosed with schistosomiasis. Of 679 children screened for schistosomiasis, 73 (10.8%) tested positive. The median age was 16.3 years [IQR 9-17.6], 74% male. The majority originated from Sub-Saharan Africa (47%) and Asia (47%). Only 40% presented with symptoms, with gastrointestinal (18%) and cutaneous (17%) manifestations being the most common. Eosinophilia was observed in 43% (median [IQR]: 1103/mm3 [671-1536]), and ova were visualised in the urine of 2/50 (4.0%). Praziquantel treatment was administered to 92%, and 5 patients required retreatment. Follow-up data were available for 58 (80%) over a median period of 9 months [IQR 6-19.8], revealing a progressive decline in eosinophil count, IgE titres, and ELISA optical density. Conclusion: In this series, the prevalence of schistosomiasis among migrant children was significant (10%), highlighting the importance of including serological tests in migrant health screening. The disease is largely asymptomatic, eosinophilia is often absent, and visualisation of ova in urine is exceedingly rare. Eosinophil count, IgE titres, and ELISA optical density could prove valuable as an initial approach for monitoring inflammation during follow-up assessments. What is Known: ⢠The burden of disease related to schistosomiasis is significant, particulary in children, and it is advisable to screen this vulnerable population. What is New: ⢠Eosinophilia may not be present in parasitic infections, so serological tests are crucial for screening migrant children. ⢠Serological monitoring facilitates long-term management of migrant children with schistosomiasis.
RESUMEN
Scarce evidence exists about the best treatment for multi-system inflammatory syndrome (MIS-C). We analyzed the effects of steroids, intravenous immunoglobulin (IVIG), and their combination on the probability of discharge over time, the probability of switching to second-line treatment over time, and the persistence of fever 2 days after treatment. We did a retrospective study to investigate the effect of different treatments on children with MIS-C from 1 March 2020 to 1 June 2021. We estimated the time-to-event probability using a Cox model weighted by propensity score to balance the baseline characteristics. Thirty of 132 (22.7%) patients were initially treated with steroids alone, 29/132 (21.9%) with IVIG alone, and 73/132 (55%) with IVIG plus steroids. The probability of early discharge was higher with IVIG than with IVIG plus steroids (hazard ratio [HR] 1.65, 95% CI 1.11-2.45, p = 0.013), but with a higher probability of needing second-line therapy compared to IVIG plus steroids (HR 3.05, 95% CI 1.12-8.25, p = 0.028). Patients on IVIG had a higher likelihood of persistent fever than patients on steroids (odds ratio [OR] 4.23, 95% CI 1.43-13.5, p = 0.011) or on IVIG plus steroids (OR 4.4, 95% CI 2.05-9.82, p < 0.001). No differences were found for this endpoint between steroids or steroids plus IVIG. Conclusions: The benefits of each approach may vary depending on the outcome assessed. IVIG seemed to increase the probability of earlier discharge over time but also of needing second-line treatment over time. Steroids seemed to reduce persistent fever, and combination therapy reduced the need for escalating treatment. What is Known: ⢠Steroids plus intravenous immunoglobulin, compared with intravenous immunoglobulin alone for multi-system inflammatory syndrome (MIS-C) might reduce the need for hemodynamic support and the duration of fever, but the certainty of the evidence is low. What is New: ⢠Intravenous immunoglobulin, steroids, and their combination for MIS-C may have different outcomes. ⢠In this study, intravenous immunoglobulin increased the probability of discharge over time, steroids reduced persistent fever, while combination therapy reduced the need for second-line treatments.

OBJECTIVES: To determine the time to reverse transcription-polymerase chain reaction (RT-PCR) negativity after the first positive RT-PCR test, factors associated with longer time to RT-PCR negativity, proportion of children seroconverting after proven severe acute respiratory syndrome coronavirus 2 infection, and factors associated with the lack of seroconversion. STUDY DESIGN: The Epidemiological Study of Coronavirus in Children of the Spanish Society of Pediatrics is a multicenter study conducted in Spanish children to assess the characteristics of coronavirus disease 2019. In a subset of patients, 3 serial RT-PCR tests on nasopharyngeal swab specimens were performed after the first RT-PCR test, and immunoglobulin G serology for severe acute respiratory syndrome coronavirus 2 antibodies was performed in the acute and follow-up (<14 and ≥14 days after diagnosis) phase. RESULTS: In total, 324 patients were included in the study. The median time to RT-PCR negativity was 17 days (IQR, 8-29 days), and 35% of patients remained positive more than 4 weeks after the first RT-PCR test. The probability of RT-PCR negativity did not differ across groups defined by sex, disease severity, immunosuppressive drugs, or clinical phenotype. Globally, 24% of children failed to seroconvert after infection. Seroconversion was associated with hospitalization, persistence of RT-PCR positivity, and days of fever. CONCLUSIONS: Time to RT-PCR negativity was long, regardless of the severity of symptoms or other patient features. This finding should be considered when interpreting RT-PCR results in a child with symptoms, especially those with mild symptoms. Seroprevalence and postimmunization studies should consider that 11 in 4 infected children fail to seroconvert.

A retrospective study that compared children younger than 6 months versus older children of a Spanish cohort of patients diagnosed with Kawasaki disease between 2011 and 2016 (Kawa-Race study). From the 598 patients recruited, 42 patients were younger than 6 months (7%) and presented more frequently with an incomplete diagnosis of Kawasaki disease (52.4 vs 27.9%, p = 0.001). Cardiac abnormalities detected by echocardiography were more common in younger patients (52.4 vs 30%, p = 0.002). These younger patients presented with a higher proportion of coronary aneurysms as well (19 vs 8.6%, p < 0.001). Shock at diagnosis (9.5 vs 1.9%, p = 0.016) and admission to intensive care units (17.7 vs 4.1%, p = 0.003) were more frequent in patients younger than 6 months. There were no statistically significant differences in relation to infections, non-response to IVIG, or mid- or long-term outcomes.Conclusion: Data of the Spanish cohort are consistent with other American and Asian studies, although Spanish children younger than 6 months had a lower rate of non-response to IVIG and better clinical outcomes. A high index of suspicion should be considered for this population due to a higher risk of coronary abnormalities, presentation of shock, and admission to the intensive care unit. What is Known: â¢Children below 6 months of age with Kawasaki disease (KD) have different features compared to older. â¢Younger patients usually have an incomplete form of KD and coronary artery abnormalities. What is New: â¢Younger than 6 months with KD presented with shock and required admission to PICU more frequently compared to older. â¢Infections play a similar role in KD despite the age of the patients.

We aimed to identify the spectrum of disease in children with COVID-19, and the risk factors for admission in paediatric intensive care units (PICUs). We conducted a multicentre, prospective study of children with SARS-CoV-2 infection in 76 Spanish hospitals. We included children with COVID-19 or multi-inflammatory syndrome (MIS-C) younger than 18 years old, attended during the first year of the pandemic. We enrolled 1200 children. A total of 666 (55.5%) were hospitalised, and 123 (18.4%) required admission to PICU. Most frequent major clinical syndromes in the cohort were mild syndrome (including upper respiratory tract infection and flu-like syndrome, skin or mucosae problems and asymptomatic), 44.8%; bronchopulmonary syndrome (including pneumonia, bronchitis and asthma flare), 18.5%; fever without a source, 16.2%; MIS-C, 10.6%; and gastrointestinal syndrome, 10%. In hospitalised children, the proportions were 28.5%, 25.7%, 16.5%, 19.1% and 10.2%, respectively. Risk factors associated with PICU admission were age in months (OR: 1.007; 95% CI 1.004 to 1.01), MIS-C (OR: 14.4, 95% CI 8.9 to 23.8), chronic cardiac disease (OR: 4.8, 95% CI 1.8 to 13), asthma or recurrent wheezing (OR: 2.5, 95% CI 1.2 to 5.2) and after excluding MIS-C patients, moderate/severe liver disease (OR: 8.6, 95% CI 1.6 to 47.6). However, asthmatic children were admitted into the PICU due to MIS-C or pneumonia, not due to asthma flare.Conclusion: Hospitalised children with COVID-19 usually present as one of five major clinical phenotypes of decreasing severity. Risk factors for PICU include MIS-C, elevation of inflammation biomarkers, asthma, moderate or severe liver disease and cardiac disease. What is Known: ⢠All studies suggest that children are less susceptible to serious SARS-CoV-2 infection when compared to adults. Most studies describe symptoms at presentation. However, it remains unclear how these symptoms group together into clinically identifiable syndromes and the severity associated with them. What is New: ⢠We have gathered the primary diagnoses into five major syndromes of decreasing severity: MIS-C, bronchopulmonary syndrome, gastrointestinal syndrome, fever without a source and mild syndrome. Classification of the children in one of the syndromes is unique and helps to assess the risk of critical illness and to define the spectrum of the disease instead of just describing symptoms and signs.

OBJECTIVE: To evaluate the nutritional, clinical and immunological status of children at HIV diagnosis in the continental region of Equatorial Guinea. METHODS: Children <18 years diagnosed with HIV between 2009 and 2017 were included. Clinical, immunological and nutritional data were collected. Weight-for-height, weight-for-age and height-for-age Z-scores were calculated using WHO Child Growth Standards. The population was assessed in two equal periods (2009-2013 and 2014-2017) from the time of diagnosis. RESULTS: A total of 213 children were diagnosed with HIV (49.3% males), median age 3.8 years (IQR: 1.5-8.2). A total of 121 cases (56.8%) were at WHO clinical stage III, and 53 (24.9%) were at WHO clinical stage IV. CDC immunological stage II was diagnosed in 51/130 (39.2%) and CDC stage III in 44/130 (33.8%). About 56.2% of children were underweight (weight-for-age <-2 SD); 20.1% moderately and 36.1% severely so. About 27.6% of children were wasted (weight-for-height <-2 SD); 11.9% moderately and 15.7% severely so. About 56.3% of children were stunted (height-for-age <-2 SD); 20.7% moderately and 35.6% severely so. The prevalence of wasting was higher in children ≤5 years than in children >5 years (36.4% vs. 19.1%, P = 0.026). In the second period, the prevalence of moderate-severe immunodeficiency decreased (87.2% to 67.0%, P = 0.018), without significant differences in the other nutritional or clinical data. Severe underweight was a risk factor for moderate-severe immunodeficiency (aOR: 4 [95% CI: 1.4-11.4], P = 0.010). CONCLUSIONS: We highlight a high proportion of malnutrition at the time of HIV diagnosis in Guinea´s paediatric population. Early diagnosis of HIV infection is a priority, achievable by training Guinea´s physicians to suspect HIV early, introducing HIV molecular diagnostic techniques and ensuring intensive nutritional treatment.
OBJECTIF: Evaluer le statut nutritionnel, clinique et immunologique des enfants au moment du diagnostic du VIH dans la région continentale de la Guinée équatoriale. MÉTHODES: Les enfants de moins de 18 ans diagnostiqués avec le VIH entre 2009 et 2017 ont été inclus. Les données cliniques, immunologiques et nutritionnelles ont été collectées. Les scores Z du poids pour la taille, du poids pour l'âge et de la taille pour l'âge ont été calculés en utilisant les normes de croissance de l'enfant de l'OMS. La population a été évaluée en deux périodes égales (2009-2013 et 2014-2017) à partir du moment du diagnostic. RÉSULTATS: 213 enfants ont été diagnostiqués avec le VIH (49,3% de sexe masculin), âge médian de 3,8 ans (IQR: 1,5-8,2). 121 cas (56,8%) étaient au stade clinique III de l'OMS et 53 (24,9%) étaient au stade clinique IV de l'OMS. Le stade immunologique II du CDC a été diagnostiqué chez 51/130 (39,2%) et le stade III du CDC chez 44/130 (33,8%). 56,2% des enfants avaient un poids insuffisant (poids pour âge <-2 écart type [ET]); 20,1% modérément et 36,1% sévèrement. 27,6% des enfants étaient émaciés (poids pour taille <-2 ET); 11,9% modérément et 15,7% sévèrement. 56,3% des enfants avaient un retard de croissance (taille pour l'âge <-2 ET); 20,7% modérément et 35,6% sévèrement. La prévalence de l'émaciation était plus élevée chez les enfants ≤5 ans que chez les enfants > 5 ans (36,4% contre 19,1%; P = 0,026). Dans la deuxième période, la prévalence de l'immunodéficience modérée à sévère a diminué (87,2% à 67,0% ; P = 0,018), sans différences significatives dans les autres données nutritionnelles ou cliniques. L'insuffisance pondérale sévère était un facteur de risque d'immunodéficience modérée à sévère (aOR: 4 [IC95%: 1,4-11,4] ; P = 0,010). CONCLUSIONS: Nous mettons en évidence ici une forte proportion de malnutrition au moment du diagnostic du VIH dans la population pédiatrique guinéenne. Le diagnostic précoce de l'infection par le VIH est une priorité, réalisable en formant les médecins guinéens à identifier le VIH tôt, en introduisant des techniques de diagnostic moléculaire du VIH et en assurant un traitement nutritionnel intensif.

Intravascular devices are essential for the diagnostic and therapeutic approach to multiple diseases in paediatrics, and central venous catheters (CVCs) are especially important. One of the most frequent complications is the infection of these devices, which is associated with a high morbidity and mortality. These infections are highly complex, requiring the use of substantial resources, both for their diagnosis and treatment, and affect vulnerable paediatric patients admitted to high-complexity units more frequently. There is less evidence on their management in paediatric patients compared to adults, and no consensus documents on the subject have been published in Spain. The objective of this document, developed jointly by the Spanish Society of Paediatric Infectious Diseases (SEIP) and the Spanish Society of Paediatric Intensive Care (SECIP), is to provide consensus recommendations based on the greatest degree of evidence available to optimize the diagnosis and treatment of catheter-related bloodstream infections (CRBSIs). This document focuses on non-neonatal paediatric patients with CRBSIs and does not address the prevention of these infections.

Mycobacterium fortuitum is a rapidly growing nontuberculous mycobacterium mainly associated with skin, soft tissue and surgical site infections. We report an unusual outbreak of 6 cases of surgical site infection following spinal surgery. Patients received combined intravenous antibiotics, including amikacin, followed by an extended period of oral therapy with favorable clinical outcomes. No instrumentation replacement was performed in any case.
RESUMEN
BACKGROUND: Data on antifungal prescribing in neonatal patients are limited to either single-center or single-country studies or to 1-day recording. Therefore, we assessed antifungal longitudinal usage in neonatal units (NUs) within Europe. METHODS: CALYPSO, a prospective weekly point prevalence study on antifungal drug usage in NUs in 18 hospitals (8 European countries), was conducted in 2020 during a 12-week period. All patients receiving systemic antifungals were included. Ward demographics were collected at the beginning; ward and patient data including indication, risk factors and antifungal regimen were weekly collected prospectively. RESULTS: Among 27 participating NUs, 15 (56%) practiced antifungal prophylaxis for neonates with birth weight <1000 g or <1500 g and additional risk factors. In total, 174 patients received antifungals with a median frequency per week of 10.5% ranging from 6.9% to 12.6%. Indication for antifungal prescribing was prophylaxis in 135/174 (78%) courses and treatment in 22% [39 courses (69% empirical, 10% preemptive, 21% targeted)]. Fluconazole was the most frequent systemic agent used both for prophylaxis (133/135) and treatment (15/39, 39%). Among neonates receiving prophylaxis, the most common risk factors were prematurity (119/135, 88%), mechanical ventilation (109/135, 81%) and central vascular catheters (89/135, 66%). However, gestational age <28 weeks was only recorded in 55/135 (41%) courses and birth weight <1000 g in 48/135 (35%). Most common reason for empirical treatment was late-onset sepsis; all 8 targeted courses were prescribed for invasive candidiasis. CONCLUSION: Antifungal usage in European NUs is driven by prophylaxis and empirical treatment with fluconazole being the most prescribed agent for both indications.
RESUMEN
Autosomal dominant hyper IgE syndrome (AD-HIES) is a primary immunodeficiency caused by loss-of-function (LOF) mutations in the Signal Transducer and Activator of Transcription 3 (STAT3) gene. In these patients, performing a correct differential diagnosis of pulmonary infections is difficult and challenging, as they usually have atypical presentations. However, establishing a correct diagnostic and therapeutic approach is essential, as pulmonary complications are responsible for high morbidity and mortality rates in these patients. We report the case of a teenage girl with AD-HIES and respiratory symptoms and fever in whom performing a correct differential diagnosis was challenging.

BACKGROUND: human adenovirus (hAdV) infection constitutes an important cause of morbidity and mortality in transplant recipients, due to their immune status. Among drugs currently available, cidofovir (CDF) is the most prescribed. METHODS: Retrospective study of hAdV infection in paediatric transplant recipients from a tertiary paediatric centre, describing characteristics, management, and outcomes, and focused on the role of CDF. RESULTS: 49 episodes of infection by hAdV were detected during a four-year period: 38 episodes in patients that received allogeneic hematopoietic stem cell transplantation (77.6%) and 11 in solid organ transplant recipients (22.4%). Twenty-five patients (52.1%) were symptomatic, presenting mainly fever and/or diarrhoea. CDF was prescribed in 24 patients (49%), with modest results. CDF use was associated with the presence of symptoms resulting in lower lymphocyte count, paediatric intensive care unit admission, and high viral load. Other therapeutic measures included administration of intravenous immunoglobulin, reducing immunosuppression, and T-lymphocyte infusion. Despite treatment, 22.9% of patients did not resolve the infection and there were three deaths related to hAdV infection. All-cause mortality was 16.7% (8 episodes) by 30 days, and 32.7% (16 episodes) by 90 days, of which, 3 episodes (3/16, 18.8%) were attributed to hAdV directly. CONCLUSIONS: hAdV infection had high morbidity and mortality in our series. CDF use is controversial, and available therapeutic options are limited. Transplant patients with low lymphocyte count are at higher risk of persistent positive viremias, and short-term survival of these patients was influenced by the resolution of hAdV infection.
RESUMEN
BACKGROUND: Epidermolysis bullosa (EB) is frequently complicated by skin infection, which can lead to bacteremia. However, bloodstream infections (BSI) in patients with EB have not been well described. METHODS: Retrospective study of BSI in children 0-18 years with EB from a national reference unit in Spain, in 2015-2020. RESULTS: Among 126 children with EB, we identified 37 BSI episodes in 15 patients (14 recessive dystrophic EB, 1 junctional EB). The most frequent microorganisms were Pseudomonas aeruginosa (n = 12) and Staphylococcus aureus (n = 11). Five P. aeruginosa isolates were ceftazidime-resistant (42%), 4 of which were also resistant to meropenem and quinolones (33%). As for S. aureus , 4 (36%) were methicillin-resistant and 3 (27%) clindamycin-resistant. In 25 (68%) BSI episodes skin cultures had been performed in the previous 2 months. The most frequent isolates were also P. aeruginosa (n = 15) and S. aureus (n = 11). In 13 cases (52%), smear and blood cultures grew the same microorganism, with the same antimicrobial resistance pattern in 9 isolates. Twelve patients (10%) died during follow-up (9 RDEB and 3 JEB). BSI was the cause of death in 1 case. In patients with severe RDEB, a history of BSI was associated with higher mortality (OR 6.1, 95% CI: 1.33-27.83, P = 0.0197). CONCLUSIONS: BSI is an important cause of morbidity in children with severe forms of EB. The most frequent microorganisms are P. aeruginosa and S. aureus , with high rates of antimicrobial resistance. Skin cultures can help guide treatment decisions in patients with EB and sepsis.

INTRODUCTION/OBJECTIVES: Asian scores developed to predict unresponsiveness to intravenous immunoglobulin (IVIG) or development of coronary artery aneurysms (CAA) in patients with Kawasaki disease (KD) are not appropriate in Western populations. The purpose of this study is to develop 2 scores, to predict unresponsiveness to IVIG and development of CAA, appropriate for Spanish population. METHOD: Data of 625 Spanish children with KD collected retrospectively (2011-2016) were used to identify variables to develop the 2 scores of interest: unresponsiveness to IVIG and development of CAA. A statistical model selected best variables to create the scores, and scores were validated with data from 98 patients collected prospectively. RESULTS: From 625 patients of the retrospective cohort, final analysis was performed in 439 subjects: 37 developed CAA, and 212 were unresponsive to IVIG. For the score to predict CAA, a cutoff ≥ 8 was considered for high risk, considering a score system with a different weight for each of the eight variables. External validation showed a sensitivity of 22% and a specificity of 75%. The score to predict unresponsiveness to IVIG established a cutoff ≥ 8 for high risk, considering a score system with a different weight for each of the nine variables. External validation showed a sensitivity of 78% and a specificity of 50%. CONCLUSIONS: Two risk scores for KD were developed from Spanish population, to predict development of CAA and unresponsiveness to IVIG; validation in other cohorts could help to implement these tools in the management of KD in other Western populations.

BACKGROUND: Pneumonia is a frequent manifestation of coronavirus disease 2019 (COVID-19) in hospitalized children. METHODS: The study involved 80 hospitals in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Spanish Pediatric National Cohort. Participants were children <18 years, hospitalized with SARS-CoV-2 community-acquired pneumonia (CAP). We compared the clinical and radiological characteristics of SARS-CoV-2-associated CAP with CAP due to other viral etiologies from ValsDance (retrospective) cohort. RESULTS: In total, 151 children with SARS-CoV-2-associated CAP and 138 with other viral CAP were included. Main clinical features of SARS-CoV-2-associated CAP were cough, fever, or dyspnea. Lymphopenia was found in 43% patients and 15% required admission to the pediatric intensive care unit (PICU). Chest X-ray revealed condensation (42%) and other infiltrates (58%). Compared with CAP from other viral pathogens, COVID-19 patients were older, with lower C-reactive protein (CRP) levels, less wheezing, and greater need of mechanical ventilation (MV). There were no differences in the use of continuous positive airway pressure (CPAP) or HVF, or PICU admission between groups. CONCLUSION: SARS-CoV-2-associated CAP in children presents differently to other virus-associated CAP: children are older and rarely have wheezing or high CRP levels; they need less oxygen but more CPAP or MV. However, several features overlap and differentiating the etiology may be difficult. The overall prognosis is good.
