Rotavirus gastroenteritis hospitalizations in provinces with different vaccination coverage rates in Spain, 2013-2018.

BACKGROUND: Rotavirus (RV) vaccines are available in Spain since 2006 but are not included in the National Immunization Program. RV vaccination has reached an intermediate vaccination coverage rate (VCR) but with substantial differences between provinces. The aim of this study was to assess the ratio of RV gastroenteritis (RVGE) admissions to all-cause hospitalizations in children under 5 years of age in areas with different VCR. METHODS: Observational, multicenter, cross-sectional, medical record-based study. All children admitted to the study hospitals with a RVGE confirmed diagnosis during a 5-year period were selected. The annual ratio of RVGE to the total number of all-cause hospitalizations in children < 5 years of age were calculated. The proportion of RVGE hospitalizations were compared in areas with low (< 30%), intermediate (31-59%) and high (> 60%) VCR. RESULTS: From June 2013 to May 2018, data from 1731 RVGE hospitalizations (16.47% of which were nosocomial) were collected from the 12 study hospitals. RVGE hospital admissions accounted for 2.82% (95 CI 2.72-3.00) and 43.84% (95% CI 40.53-47.21) of all-cause and Acute Gastroenteritis (AGE) hospitalizations in children under 5 years of age, respectively. The likelihood of hospitalization due to RVGE was 56% (IC95%, 51-61%) and 27% (IC95%, 18-35%) lower in areas with high and intermediate VCR, respectively, compared to the low VCR areas. CONCLUSIONS: RVGE hospitalization ratios are highly dependent on the RV VCR. Increasing VCR in areas with intermediate and low coverage rates would significantly reduce the severe burden of RVGE that requires hospital management in Spain.

Clinical practice update of antifungal prophylaxis in immunocompromised children.

Due to the rise in the number and types of immunosuppressed patients, invasive fungal infections (IFI) are an increasing and major cause of morbidity and mortality in immunocompromised adults and children. There is a broad group of pediatric patients at risk for IFI in whom primary and/or secondary antifungal prophylaxis (AFP) should be considered despite scant evidence. Pediatric groups at risk for IFI includes extremely premature infants in some settings, while in high-risk children with cancer receiving chemotherapy or undergoing haematopoietic stem cell transplantation (HCT), AFP against yeast and moulds is usually recommended. For solid organ transplanted, children, prophylaxis depends on the type of transplant and associated risk factors. In children with primary or acquired immunodeficiency such as HIV or long-term immunosuppressive treatment, AFP depends on the type of immunodeficiency and the degree of immunosuppression. Chronic granulomatous disease is associated with a particular high-risk of IFI and anti-mould prophylaxis is always indicated. In contrast, AFP is not generally recommended in children with long stay in intensive care units. The choice of AFP is limited by the approval of antifungal agents in different age groups and by their pharmacokinetics characteristics. This document aims to review current available information on AFP in children and to provide a comprehensive proposal for each type of patient.

Citrulina plasmática como marcador de pérdida de masa enterocitaria en la enfermedad celíaca en la infancia / Plasma citrulline as a marker of loss of enterocitary mass in coeliac disease in childhood

Introducción: La citrulina plasmática no está incorporada a las proteínas endógenas ni exógenas y constituye un teórico marcador de la atrofia vellositaria. El objetivo del estudio es relacionar los niveles plasmáticos de citrulina y arginina con la severidad de la afectación de la mucosa intestinal en pacientes celiacos. Material y métodos: Estudio transversal de cohortes en niños entre 16 meses y 14 años: 46 con enfermedad celíaca al diagnóstico; 9 celíacos siguiendo dieta sin gluten y 42 controles. Se determina concentración plasmática de aminoácidos, en mmol/L, y variables clínicas y analíticas asociadas. Resultados: No diferencias estadísticamente significativas en IMC, edad o función renal, con ligero incremento de esteatorrea en celíacos. Citrulina, arginina y glutamina plasmáticas significativamente más bajas en los casos (17,7 μmol/l, 38,7 μmol/l, 479,6 μmol/l respectivamente)que en controles (28,9 μmol/l, 56,2 μmol/l, 563,7μmol/l). Citrulina plasmática significativamente más baja en grados avanzados de atrofia (13,8 μmol/l vs 19,7μmol/l, p < 0,05), no así con el resto de aminoácidos. Discusión: La medida postabsortiva de citrulina plasmática constituye buen marcador de reducción de masa enterocitaria en celíacos con atrofia vellositaria; secundariamente disminución también de arginina. Grados bajos de alteración histológica de la biopsia intestinal son suficientes como para diferenciar su citrulina de los controles y además se puede afirmar que grados altos de lesión histológica tienen menor citrulina plasmática que grados bajos (AU)

Introduction: Plasma citrulline is not incorporated in endogenous or exogenous proteins so it is a theoretical marker of villous atrophy. Our aim was to correlate plasma citrulline levels with severity of villous atrophy inceliac patients. Methods: Observational case-control study longitudinal in children 16 month-old to 14 year-old: 48 with untreated celiac disease, 9 celiac children under gluten free diet and 35 non-celiac healthy children. Plasma amino acids concentration is determined, expressed inμmol/L, and so are other clinical and analytical data. Results: No statistically significative difference found in the referring to BMI, age or renal function. Small increase in fecal fat in celiac children. Citrulline, arginine and glutamine are significantly lower in cases (17.7μmol/l, 38.7 μmol/l, 479.6 μmol/l respectively) than in controls(28.9 μmol/l, 56.2 μmol/l, 563.7 μmol/l). Citrulline levels are significantly lower in the severe degrees of atrophy than in mild ones (13.8 μmol/l vs. 19.7 μmol/l, p <0.05), not happening so with rest of amino acids. Summary: Postabsortive mean of plasma citrulline is a good marker of reduction in enterocyte mass in celiac patients with villous atrophy; secondary reduction in plasma arginine too. Just a small histological alteration in intestinal biopsy is enough to differentiate citrulline incases and controls and besides it can be seen that high levels of atrophy present with lower plasma citrulline (AU)
