RESUMO
Several studies have shown the effects of e-cigarettes in adults. Nowadays, few data are available in the pediatric population. This study aims to assess the relationship between asthma exacerbations and home exposure to e-cigarettes. We conducted a pilot, retrospective, monocenter, observational study. Demographic and clinical data were collected, including number of asthma exacerbations, need for rescue therapy and/or therapeutic step-up, and Asthma Control Test (ACT) and children-Asthma Control Test (c-ACT) scores. The cohort consisted of 54 patients (5-17 years old), divided into two groups: A, including patients exposed to e-cigarette aerosols; B, including unexposed patients. The statistical analysis showed no relevant variation in the number of asthma symptomatic days and need for rescue therapy in group A versus group B (p = 0.27 and 0.19, respectively). There were no statistically significant variations when also considering the number of patients who needed a therapeutic step-up (p = 0.3). The mean values of ACT and c-ACT were, respectively, 17.2 ± 7.6 and 18.3 ± 5.6 in group A and 19.6 ± 3.8 and 14.6 ± 5.8 in group B (p = 0.3 and 0.4, respectively). Although we did not find a statistically significant correlation between second-hand e-cigarette exposure and asthma exacerbations, our findings suggest that asthmatic children exposed second-hand to e-cigarettes may have increased risk of asthma symptomatic days. Future research is warranted.
RESUMO
INTRODUCTION: The aim of this study is to evaluate a possible negative action of lockdown, during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, in the follow-up of juvenile idiopathic arthritis (JIA) patients. METHODS: We compared the number of JIA reactivations in the period March-July 2020 to the same months of 2018 and 2019. RESULTS: A total of 10 JIA reactivations have been documented on 58 patients (17%) visited in the period March-July 2018; 10 reactivations on 61 patients (16%) in the period March-July 2019; and 19 reactivations on 39 patients (49%) in the period March-July 2020, with a statistically significant increase (p <0.001). The other 19 patients who should have been visited during the same period, contacted by phone, indicated remission. Therefore, we hypothesize that the effective number of reactivations in the period March-July 2020 would be 19/58 patients (33%) which remains significantly greater than in the previous 2 years (p < 0.05). Among the 19 JIA patients reactivated in 2020, 3 spontaneously stopped the basic treatment due to parents' choice for fear of serious complications in case of SARS-CoV-2 infection and 4 had poor compliance with underlying treatment. In addition, 14/19 reactivated JIA patients did not perform the scheduled check according to the follow-up. In fact, the mean time interval between two follow-up visits was significantly greater in 2020 (157 ± 53 days, p < 0.0001) vs 2018 (108 ± 68 days) and 2019 (107 ± 40 days). CONCLUSIONS: We have found a significant increase in JIA reactivations in the period March-July 2020 compared to the same interval of 2018 and 2019. This increase may have been caused by poor compliance with background treatment, as documented in 7/19 JIA patients reactivated, and by a greater interval in follow-up checks. Therefore, it is necessary, in occasion of a new pandemic and lockdown, to implement greater controls using more appropriate telemedicine tools. Key Points ⢠COVID-19 pandemic lockdown had a negative effect on the follow-up of JIA patients. ⢠A significant increase in JIA reactivations was found during the lockdown. ⢠Poor therapeutic compliance and follow-up checks have been proven during the lockdown. ⢠It is necessary to improve telemedicine tools and scientific information during a pandemic and lockdown.
