Assessment and management of asthma exacerbations in an emergency department unit.

BACKGROUND: The Pediatric Respiratory Assessment Measure (PRAM) score is a useful tool for the assessment of asthma exacerbations in children. This study aimed to estimate the risk of hospitalization in children, assessed with the PRAM score and having mild-moderate asthma exacerbation, who were treated with salbutamol delivered via a metered-dose inhaler and spacer (MDI/S). METHODS: The study population consisted of children aged 3-16 years with mild-moderate asthma exacerbations. All children received 1mg/kg prednisolone p.o. (max 40 mg) and 4-6 puffs of salbutamol via MDI/S. RESULTS: Fifty patients participated in the study. Admission was associated positively with the initial PRAM score (OR: 18.91, CI: 2.42-123.12, P = 0.005) and negatively with the improvement in PRAM score (OR: 0.52, CI: 0.01-0.78, P = 0.032). CONCLUSION: PRAM is a reliable tool that can be used effectively to estimate the asthma exacerbation severity.

Parental Education and the Association between Fruit and Vegetable Consumption and Asthma in Adolescents: The Greek Global Asthma Network (GAN) Study.

BACKGROUND: Evidence suggests that nutritional factors, such as consumption of fruits and vegetables, along with socioeconomic factors such as parental education level, are associated with asthma prevalence. Our study examined the role of parental education in the association between fruit and vegetable consumption and adolescent asthma. METHODS: 1934 adolescents (mean age: 12.7 years, standard deviation: 0.6 years, boys: 47.5%) and their parents were voluntarily enrolled and completed a validated questionnaire assessing current asthma status, fruit and vegetable consumption and parental educational level. Participants were categorized as high or low intake for five food groups: fruits, cooked vegetables, raw vegetables, all vegetables (cooked and raw), and all three food groups together (fruits and all vegetables). RESULTS: Adolescents who were high consumers of all three food groups (fruits, cooked and raw vegetables) were less likely to have asthma, adjusted for several confounders (adjusted odds ratio (aOR): 0.53, 95% confidence interval (CI): 0.25-0.97). Moreover, in adolescents who had parents with tertiary education and were in the high consumption of all three food groups, the inverse association was almost twofold higher than the one for adolescents with parents of primary/secondary education (aOR: 0.35, 95% CI: (0.21-0.89) and aOR: 0.61, 95% CI: (0.47-0.93) respectively). CONCLUSIONS: Our findings highlight the importance of the adoption of a diet rich in fruits and vegetables for all asthmatic adolescents and emphasize the important role of parental influences in this association.

Use of point-of-care molecular tests reduces hospitalization and oseltamivir administration in children presenting with influenza-like illness.

Influenza is associated with increased morbidity, healthcare costs, hospitalization rates, and mortality in children. Rapid immunochromatography assay (ICA), a test with low sensitivity, is often used as point-of-care (POC) test. Recently, the rapid syndromic molecular test FilmArray has become available. This observational study aims to evaluate whether the use of FilmArray would decrease the use of antivirals and hospitalization rates among children presenting to the emergency room (ER) with influenza-like illness (ILI) symptoms. Nasopharyngeal swabs were prospectively collected from children, aged 0-16 years, presenting with ILI at the ER of a tertiary hospital during the peak endemic period. Patients were allocated to be tested by either FilmArray or ICA. The use of antivirals and hospitalization rates were noted. Logistic regression models were used to investigate the impact of testing methods on decision-making. Overall, 80 children were included (mean age: 5 years). Admissions were more likely to occur if an ICA test was performed (OR, 3.16; 95% CI, 1.01-9.82; p = .046). Oseltamivir administration was more likely among children who had undergone the ICA test (OR, 4.67; 95% CI, 1.06-20.43; p = .041). The implementation of rapid molecular test had no impact on complementary diagnostic testing or antibacterial prescription. The use of FilmArray significantly reduced both hospitalization and oseltamivir administration in children. Further knowledge on the use of POC tests is required to improve current management of children presenting with ILI and decrease associated healthcare costs.

Longitudinal changes in lung function following initiation of lumacaftor/ivacaftor combination.

BACKGROUND: The combination of lumacaftor and ivacaftor (LUM/IVA) is a recently approved CFTR modulator treatment for homozygous F508del CF patients. Our study aimed at evaluating the change in the rate of lung function decline after one-year treatment with LUM/IVA. METHODS: The study evaluated patients homozygous for F508del, 12 to 23 years old. All had been treated for one year with LUM/IVA. The collected data included the percent predicted values of FEV1 (ppFEV1) and FVC (ppFVC), and the FEV1/FVC ratio (FEV1/FVC), that corresponded to 12, 24, and 36 months prior to, and 12 months after the initiation of LUM/IVA; also, the 3 highest values of the ppFEV1 (and the corresponding ppFVC, and FEV1/FVC) for the periods 0-12 months, 12-24 months, and 24-36 months prior to as well as the 12-month period after the initiation of LUM/IVA. The baseline lung function was estimated before the commencement of the drug. Data were analyzed longitudinally with generalized estimating equations models and continuous linear splines. A single knot was used that corresponded to the time point of LUM/IVA initiation. RESULTS: Fifty-two patients were analyzed. The multivariate longitudinal analysis of spirometric indices with linear splines demonstrated a significant change in the slopes of ppFEV1 and ppFVC decline, reflecting a significant improvement after the initiation of LUM/IVA treatment. CONCLUSIONS: In this real-world study, lung function improved over a relatively short time period of only one year, after the commencement of LUM/IVA.
