Childhood asthma outcomes during the COVID-19 pandemic: Findings from the PeARL multinational cohort
Background The interplay between COVID-19 pandemic and asthma in children is still unclear. We evaluated the impact of COVID-19 pandemic on childhood asthma outcomes.Methods The PeARL multinational cohort included 1,054 children with asthma and 505 non-asthmatic children aged between 4 and 18 years from 25 pediatric departments, from 15 countries globally. We compared the frequency of acute respiratory and febrile presentations during the first wave of the COVID-19 pandemic between groups and with data available from the previous year. In children with asthma, we also compared current and historical disease control.Results During the pandemic, children with asthma experienced fewer upper respiratory tract infections, episodes of pyrexia, emergency visits, hospital admissions, asthma attacks, and hospitalizations due to asthma, in comparison with the preceding year. Sixty-six percent of asthmatic children had improved asthma control while in 33% the improvement exceeded the minimal clinically important difference. Pre-bronchodilatation FEV1 and peak expiratory flow rate were improved during the pandemic. When compared to non-asthmatic controls, children with asthma were not at increased risk of LRTIs, episodes of pyrexia, emergency visits, or hospitalizations during the pandemic. However, an increased risk of URTIs emerged.Conclusion Childhood asthma outcomes, including control, were improved during the first wave of the COVID-19 pandemic, probably because of reduced exposure to asthma triggers and increased treatment adherence. The decreased frequency of acute episodes does not support the notion that childhood asthma may be a risk factor for COVID-19. Furthermore, the potential for improving childhood asthma outcomes through environmental control becomes apparent.</p
Suivi de plus de 10 ans de 20 patients atteints de Dyskinésie Ciliaire Primitive
Cette Ă©tude prĂ©sente une cohorte pĂ©diatrique de patients atteints de dyskinĂ©sie ciliaire primitive suivis pendant plus de 10 ans. Son objectif est de dĂ©crire l'Ă©volution clinique, fonctionnelle et radiologique puis d'identifier des facteurs pronostics. Les donnĂ©es de 20 patients ont Ă©tĂ© recueillies de façon rĂ©trospective. La dyskinĂ©sie ciliaire primitive est une maladie dont l'atteinte prĂ©dominante est pulmonaire. Cette Ă©tude confirme l'intĂ©rĂȘt d'un diagnostic prĂ©coce et montre une Ă©volution vers une aggravation lente de l'obstruction bronchique et des lĂ©sions pulmonaires. Les formes rĂ©vĂ©lĂ©es prĂ©cocement ont une Ă©volution plus sĂ©vĂšre et nĂ©cessitent une prise en charge rigoureuse. La kinĂ©sithĂ©rapie et particuliĂšrement le sport constituent les Ă©lĂ©ments majeurs du traitement.BREST-BU MĂ©decine-Odontologie (290192102) / SudocSudocFranceF

New insights into pediatric idiopathic pulmonary hemosiderosis: the French RespiRare(R) cohort.
International audienceBACKGROUND: Idiopathic pulmonary hemosiderosis (IPH) is a rare cause of alveolar hemorrhage in children and its pathophysiology remains obscure. Classically, diagnosis is based on a triad including hemoptysis, diffuse parenchymal infiltrates on chest X-rays, and iron-deficiency anemia. We present the French pediatric cohort of IPH collected through the French Reference Center for Rare Lung Diseases (RespiRare(R), www.respirare.fr). METHODS: Since 2008, a national network/web-linked RespiRare(R) database has been set up in 12 French pediatric respiratory centres. It is structured as a medical recording tool with extended disease-specific datasets containing clinical information relevant to all forms of rare lung diseases including IPH. RESULTS: We identified 25 reported cases of IPH in children from the database (20 females and 5 males). Among them, 5 presented with Down syndrome. Upon diagnosis, median age was 4.3 [0.8-14.0] yrs, and the main manifestations were: dyspnea (n = 17, 68%), anemia (n = 16, 64%), cough (n = 12, 48%), febrile pneumonia (n = 11, 44%) and hemoptysis (n = 11, 44%). Half of the patients demonstrated diffuse parenchymal infiltrates on chest imaging, and diagnosis was ascertained either by broncho-alveolar lavage indicating the presence of hemosiderin-laden macrophages (19/25 cases), or lung biopsy (6/25). In screened patients, initial auto-immune screening revealed positive ANCA (n = 6, 40%), ANA (n = 5, 45%) and specific coeliac disease antibodies (n = 4, 28%). All the patients were initially treated by corticosteroids. In 13 cases, immunosuppressants were introduced due to corticoresistance and/or major side effects. Median length of follow-up was 5.5 yrs, with a satisfactory respiratory outcome in 23/25 patients. One patient developed severe pulmonary fibrosis, and another with Down syndrome died as a result of severe pulmonary hemorrhage. CONCLUSION: The present cohort provides substantial information on clinical expression and outcomes of pediatric IPH. Analysis of potential contributors supports a role of auto-immunity in disease development and highlights the importance of genetic factors

Pneumocystis primary infection in infancy: additional french data and review of the literature
Data on features of Pneumocystis primary infection in infancy are still fragmented. To study Pneumocystis primary infection, 192 infants who were monitored for acute pulmonary disease or fever over a 40-month period were retrospectively investigated. P. jirovecii detection on archival nasopharyngeal aspirates was performed using a qPCR assay. Factors associated with P. jirovecii were assessed using univariate and multivariate analyses. P. jirovecii genotypes in infants and a control group of adults contemporaneously diagnosed with Pneumocystis pneumonia were identified using unilocus, bilocus, and multilocus sequence typing (MLST). P. jirovecii was detected in 35 infants (18.2%). The univariate analysis pointed out four factors: viral infection (P = .035, OR [IC 95], 2.2 [1.1-4.7]), lower respiratory tract infection (P = .032, OR [IC 95], 2.5 [1.1-5.9]), absence of hospital discharge after birth (P = .003, OR (IC 95), 0.1 (0.02-0.5]), and the 63-189-day group (P < .001, OR [IC 95], 42.2 [5.4-332]). The multivariate analysis confirmed these two latter factors (P = .02, OR [IC 95], 0.1 [0.02-0.72]; P = .005, OR [IC 95], 11.5 [2.1-63.5]). Thus, P. jirovecii acquisition mostly takes place in the community. A comparison of these data with those of previously published studies showed that median and interquartile range of positive-infant ages were close to those observed in Chile, Denmark, and Peru, highlighting similar characteristics. Common unilocus or bilocus genotypes were identified in infants and adults, whereas no MLST genotypes were shared. Therefore, a common reservoir made up of infected infants and adults is still hypothetical. Finally, primary infection is a worldwide phenomenon occurring at the same time in childhood regardless of geographical location, rather than an incidental event.European Commission (ERANet-LAC): CAPRI-PC HID-0254
