RESUMEN
INTRODUCTION: Respiratory tract disorders are common in children. However, there is no available data on the prescription of respiratory medications for children in France. This study aimed to provide an overview of medications for obstructive airway diseases prescriptions for children during the initial ten years of their lives within POMME, a French population-based cohort of children. MATERIAL AND METHODS: This longitudinal, population-based study used data from the French POMME birth cohort, comprising children born in Haute Garonne between July 2010 and June 2011. Anonymous medical information, including medication reimbursement data, was collected between ages 0 and 10 years. Exposure was defined as at least one prescription for respiratory medications (ATC code R03*), focusing on specific subclasses. Data were analyzed by age, season, and prescribing physicians' specialties. RESULTS: Out of 5,956 children, 4,951 (83.1%) received respiratory medication prescriptions. Inhaled corticosteroids (ICSs) were the most prescribed (95.3%), followed by short-acting ß2-agonists (68.8%). The number of prescriptions increased with age, except for ICSs alone, which peaked between 6 months and 2 years. The average number of prescriptions per child was relatively low. Prescriptions were more frequent in winter, contrary to expectations of spring allergies. DISCUSSION: This study highlighted high prescription rates of respiratory medications in children under 10 years, with ICSs being the most prevalent. While these medications are primarily intended for asthma management, the findings suggested a significant proportion of off-label prescriptions, especially in young children. Further research and clinical guidance are warranted to ensure appropriate medication use in the pediatric population.
RESUMEN
The objective of this cohort study was to describe the French population of pregnant women vaccinated against coronavirus disease 2019 (COVID-19), their pregnancy outcomes and the health status of their newborns (malformation rate, neonatal diseases, etc.), and to proactively collect and analyze reported adverse reactions over time. We conducted a prospective study using an online questionnaire. Women vaccinated during pregnancy who wanted to participate were asked to complete an inclusion questionnaire (dates of pregnancy and vaccination COVID-19, etc.), a questionnaire on the potential occurrence of adverse reactions (time of onset, type of adverse reaction, etc.) of the vaccination, sent 1 month after the injection, and a final questionnaire on the outcome of the pregnancy and the health status of the child. A total of 938 women were prospectively included in this first French study. A total of 132 women reported having had at least 1 adverse reaction following vaccination during pregnancy (14.1%), including few 'serious' adverse reaction (5.3%). There were no signals of adverse reactions during continuous monitoring. Among the 938 pregnant women, 22.4% received the vaccination COVID-19 during the first trimester, 64.2% during the second and 33.4% during the third trimester (some women have had several injections in different trimesters). Among the 938 women, 4.3% developed gestational hypertension and 13.9% diabetes; 3.3% had intrauterine growth restriction and 7.8% threatened preterm delivery. These rates are comparable to those observed in the French general population. Among live births, the rate of preterm birth was 5.1%. We reported a prevalence of major malformations of 3.9%, which is comparable to that reported by European Surveillance of Congenital Anomalies (EUROCAT), with a rate of 3.5% of major malformations in the general population of mainland France. In conclusion, our study did not demonstrate any particular safety signals in the event of vaccination with a Covid-19 vaccine during pregnancy.
RESUMEN
PURPOSE: To describe ocular anomalies (OAs) in children and fetuses in a French general population, to estimate their prevalence, and to investigate a possible association between prenatal medication exposure and the occurrence of OA in utero or in early childhood. METHODS: We conducted a case-control study using the EFEMERIS cohort, a database containing pregnancies registered in Haute-Garonne and their outcomes. We collected OA descriptions of fetuses at the time of pregnancy termination or of children at birth and the results of eye examinations of children at 9 months and 2 years of age. RESULTS: The prevalence of overall OAs was 2.13%, of which 0.04% were congenital ocular malformations (COMs). A total of 2,968 cases and 136,619 controls were selected for analysis. There was a significant difference between the two groups with regard to prenatal exposure to medications for the digestive tract and metabolism, the cardiovascular system, and the respiratory system. Multivariable analysis revealed an increased risk of OA in children of mothers exposed to magnesium during and 1 month before pregnancy (OR = 1.24; 95% CI, 1.11-1.38). CONCLUSIONS: This first pharmaco-epidemiological study on OA in France suggests that OA may be associated with exposure to commonly used medications. Given the rarity of COM, larger, international studies are warranted.
