Impact of COVID19 pandemic on patients with rare diseases in Spain, with a special focus on inherited metabolic diseases.

Introduction: The Covid-19 pandemic soon became an international health emergency raising concern about its impact not only on physical health but also on quality of life and mental health. Rare diseases are chronically debilitating conditions with challenging patient care needs. We aimed to assess the quality of life and mental health of patients with rare diseases in Spain, with a special focus on inherited metabolic disorders (IMD). Methods: A prospective case-control study was designed, comparing 459 patients suffering from a rare disease (including 53 patients with IMD) and 446 healthy controls. Quality of life (QoL) and mental health were assessed using validated scales according to age: KINDL-R and the Pediatric Symptom Checklist (PSC) for children and the WhoQoL-Bref questionnaire, GAD and PHQ-9 in adults. Results: First, children and adults (but not adolescents) with IMD showed greater psychological effects than controls (p = 0.022, p = 0.026 respectively). Second, when comparing QoL, only adult patients with IMD showed worse score than controls (66/100 vs 74,6/100 respectively, p = 0.017). Finally, IMD had better quality of life than other rare neurological and genetic diseases (p = 0.008) or other rare diseases (p < 0.001 respectively) but similar alteration of the mental status. Conclusions: Our data show that the pandemic had a negative impact on mental health that is more evident in the group of patients with IMD. Young age would behave as a protective factor on the perception of QoL. Furthermore, patients with IMD show a better QoL than other rare diseases.

Social, Academic, and Health Status Impact of Long COVID on Children and Young People: An Observational, Descriptive, and Longitudinal Cohort Study.

There is a lack of evidence of the health impacts due to long COVID among children and young people (CYP). The objective of this study is to determine the main clinical characteristics of long COVID in CYP and to investigate the academic, social, and health status impacts of long COVID in this population. An observational, descriptive, and longitudinal study on CYP who presented COVID-19 symptoms for more than twelve weeks after SARS-CoV-2 infection was performed between December 2020 and May 2021. Fifty CYP were included, with a median age of 14.1 years, 33 (66%) were female, and 17 (34%) had a relative diagnosed with long COVID. Since the initial infection and up to the first visit, CYP had persisting symptoms for a median of 4.1 months, and for 18 (36%) CYP these symptoms persisted for more than 6 months. Fatigue (100%), neurocognitive disorders (74%), muscular weakness (74%), and headache (72%) were the most reported symptoms. A total of 9 (18%) CYP could not attend school, 17 (34%) had a reduced schedule, 33 (66%) showed a decreased school performance, and 68% had stopped extracurricular activities. This preliminary study shows the impact that long COVID has on the health, academic, and social life of CYP.

Epigenetic profiling linked to multisystem inflammatory syndrome in children (MIS-C): A multicenter, retrospective study.

Background: Most children and adolescents infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remain asymptomatic or develop a mild coronavirus disease 2019 (COVID-19) that usually does not require medical intervention. However, a small proportion of pediatric patients develop a severe clinical condition, multisystem inflammatory syndrome in children (MIS-C). The involvement of epigenetics in the control of the immune response and viral activity prompted us to carry out an epigenomic study to uncover target loci regulated by DNA methylation that could be altered upon the appearance of MIS-C. Methods: Peripheral blood samples were recruited from 43 confirmed MIS-C patients. 69 non-COVID-19 pediatric samples and 15 COVID-19 pediatric samples without MIS-C were used as controls. The cases in the two groups were mixed and divided into discovery (MIS-C = 29 and non-MIS-C = 56) and validation (MIS-C = 14 and non-MIS-C = 28) cohorts, and balanced for age, gender and ethnic background. We interrogated 850,000 CpG sites of the human genome for DNA methylation variants. Findings: The DNA methylation content of 33 CpG loci was linked with the presence of MIS-C. Of these sites, 18 (54.5%) were located in described genes. The top candidate gene was the immune T-cell mediator ZEB2; and others highly ranked candidates included the regulator of natural killer cell functional competence SH2D1B; VWA8, which contains a domain of the Von Willebrand factor A involved in the pediatric hemostasis disease; and human leukocyte antigen complex member HLA-DRB1; in addition to pro-inflammatory genes such as CUL2 and AIM2. The identified loci were used to construct a DNA methylation profile (EPIMISC) that was associated with MIS-C in both cohorts. The EPIMISC signature was also overrepresented in Kawasaki disease patients, a childhood pathology with a possible viral trigger, that shares many of the clinical features of MIS-C. Interpretation: We have characterized DNA methylation loci that are associated with MIS-C diagnosis. The identified genes are likely contributors to the characteristic exaggerated host inflammatory response observed in these patients. The described epigenetic signature could also provide new targets for more specific therapies for the disorder.

Clinical characteristics, health care resource utilization and direct medical costs of Rotavirus hospitalizations in Spain (2013-2018).

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.

Macrolide resistance and molecular typing of Mycoplasma pneumoniae infections during a 4 year period in Spain.

BACKGROUND: Mycoplasma pneumoniae (MP) causes community-acquired pneumonia affecting mainly children, and tends to produce cyclic outbreaks. The widespread use of macrolides is increasing resistance rates to these antibiotics. Molecular tools can help in diagnosis, typing and resistance detection, leading to better patient management. OBJECTIVES: To assess the MP genotypes and resistance pattern circulating in our area while comparing serological and molecular diagnosis of MP. METHODS: Molecular and serological diagnosis of MP was performed in 821 samples collected in Badalona (Barcelona, Spain) from 2013 to 2017. Multiple locus variable number tandem repeat analysis (MLVA) and macrolide resistance detection by pyrosequencing were performed in those cases positive by PCR. Presence of respiratory viruses and relevant clinical data were also recorded. RESULTS: MP was detected in 16.8% of cases by PCR, with an overall agreement with serology of 76%. Eleven different MLVA types were identified, with 4-5-7-2 (50.1%) and 3-5-6-2 (29.2%) being the most abundant, with the latter showing a seasonal increase during the study. A total of 8% of the strains harboured a point substitution associated with macrolide resistance, corresponding mainly to an A2063G 23S rRNA mutation and directly related to previous macrolide therapy. Analysis of respiratory viruses showed viral coinfections in most cases. CONCLUSIONS: Serological and molecular tools combined could improve MP diagnosis and the analysis of its infection patterns. Macrolide resistance is associated with previous therapy. Given that MP pneumonia usually resolves spontaneously, it should be reconsidered whether antibiotic treatment is suitable for all cases.

Hospitalizaciones infantiles asociadas a infección por virus de la gripe en 6 ciudades de España (2014-2016) / Child hospital admissions associated with influenza virus infection in 6 Spanish cities (2014-2016)

Introducción: La información existente sobre el impacto de la gripe en la población infantil española es escasa. El presente trabajo pretende aumentar este conocimiento estudiando aspectos clave como la incidencia de hospitalización, clínica, comorbilidades y el estado vacunal en los niños hospitalizados. Métodos: Estudio retrospectivo, observacional, por revisión de historias clínicas, en menores de 15 años hospitalizados por gripe adquirida en la comunidad, confirmada microbiológicamente, durante 2 temporadas gripales (2014-2015 y 2015-2016). El estudio se realizó en 10 hospitales de 6 ciudades, que atienden aproximadamente al 12% de la población infantil española. Resultados: Fueron hospitalizados 907 niños con diagnóstico principal de gripe (447 < 2 años), con una tasa media anual de incidencia de hospitalización de 0,51 casos/1.000 niños (IC del 95% 0,48-0,55). El 45% presentó enfermedades subyacentes consideradas factores de riesgo para gripe grave, y la mayor parte de ellos (74%) no habían sido vacunados. El porcentaje con enfermedades subyacentes aumentó con la edad, desde el 26% en menores de 6 meses al 74% en mayores de 10 años. El 10% de los casos (n = 92) precisaron cuidados intensivos pediátricos por fallo respiratorio agudo. Conclusión: La gripe es causa importante de hospitalización en la población infantil española. Los menores de 6 meses de edad y los niños con enfermedades subyacentes constituyen una parte mayoritaria (> 50%) de los casos. Una gran parte de las formas graves de gripe en población infantil podrían ser evitada si se cumplieran las indicaciones actuales de vacunación

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 2́ flu 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

Infecció pel virus Zika / Infección por virus Zika / Zika virus infection

Fonament: la infecció pel virus Zika (ZIKV) ha esdevingut un tema de gran interès per a la comunitat científica en els darrers mesos. La necessitat de caracteritzar el virus i com-prendre els mecanismes de transmissió d'aquesta «nova» infecció emergent han fet que durant l'últim any el nombre de publicacions sobre el tema no hagi parat de créixer. És per això que creiem necessària una revisió de la bibliografia publicada fins al moment que ens permeti entendre una mica millor aquesta infecció. Objectiu: conèixer l'epidemiologia, les vies de transmissió, les manifestacions clíniques, les complicacions, el diagnòstic i les mesures de prevenció descrites fins ara en relació amb la infecció pel ZIKV. Mètode: revisió narrativa de la bibliografia publicada sobre el tema, tant a nivell nacional com internacional, fins al juny del 2016. Resultats: existeix una àmplia bibliografia que tracta sobre diferents aspectes en relació amb la infecció pel ZIKV. Continua sent un tema d'actualitat científica sobre el qual manquen molts aspectes per caracteritzar. Conclusions: la infecció pel ZIKV comparteix molts aspectes amb la infecció per altres arbovirus. No obstant això, presenta característiques que el diferencien d'altres infeccions per virus de la mateixa família (múltiples vies de transmissió potencial, teratogenicitat, complicacions postinfeccioses) i que fan que encara sigui necessària la recerca per poder caracteritzar la infecció per aquest virus emergent

Fundamento. La infección por el virus Zika (ZIKV) se ha convertido en un tema de gran interés para la comunidad científica en los últimos meses. La necesidad de caracterizar el virus y comprender los mecanismos de transmisión de esta «nueva» infección emergente han hecho que durante el último año el número de publicaciones al respecto no haya parado de crecer. Es por ello que creemos necesaria una revisión de la bibliografía publicada hasta el momento que nos permita entender un poco mejor la infección por ZIKV. Objetivo. Conocer la epidemiología, las vías de transmisión, las manifestaciones clínicas, las complicaciones, el diagnóstico y las medidas de prevención descritas hasta ahora en relación a la infección por ZIKV. Método. Revisión narrativa de la bibliografía publicada al respecto, tanto a nivel nacional como internacional, hasta junio de 2016. Resultados. Existe amplia bibliografía que trata sobre diferentes aspectos en relación a la infección por ZIKV. Sigue siendo un tema de actualidad científica sobre el que faltan muchos aspectos para caracterizar. Conclusiones. La infección por ZIKV comparte muchos aspectos con la infección por otros arbovirus. No obstante, presenta características que lo diferencian de otras infecciones por virus de la misma familia (múltiples vías de transmisión potencial, teratogenicidad, complicaciones postinfecciosas) y que hacen que aún sea necesaria la investigación para poder caracterizar la infección por este virus emergente (AU)

Background. Zika virus infection (ZIKVI) has recently become a topic of great interest for the scientific community. The need to characterize the virus and to understand the transmission mechanisms of this newly emerging infection has increased the number of publications related to this topic. For this reason, a review of the literature published to date is necessary to allow us a better understanding of ZIKVI. Objective. To identify the epidemiology, transmission routes, clinical manifestations, complications, diagnosis and prevention measures described so far in relation to ZIKVI. Method. Narrative review of national and international literature published about the topic until June 2016. Results. There is extensive literature that discusses different aspects related to ZIKVI. It still remains a subject of scientific discussion and there are missing aspects to characterize. Conclusions. ZIKVI shares many aspects with other Arbovirus infections. However, it has some characteristics that distinguish it from other infections by viruses from the same family (multiple potential routes of transmission, teratogenicity, infectious complications) and that make research necessary in order to better help characterize this emerging viral infection (AU)
