Self-reported adverse reactions to subcutaneous airborne allergen immunotherapy: a real-life, single center study.

Summary: Background. To estimate the prevalence of self-reported adverse reactions (AdR) to subcutaneous airborne allergen immunotherapy (SCIT) and to describe factors associated with its occurrence. Methods. Real-life, observational, descriptive study of all patients treated with SCIT at a Portuguese allergy unit between 03/2017 and 06/2019, and who answered ≥ 1 time to a pre-SCIT evaluation questionnaire assessing the occurrence of local and/or systemic AdR in the previous administration. Results. 939 questionnaires from 231 patients (42% female, 35% with asthma) were included. Most (60%) SCIT preparations had multiple allergens with concentration adjusted to prevent dilution (MA-NoDil), 26% were single allergen with standard concentration (SA-SC), 10% single allergen with higher than standard concentration (SA-HC), and 4% mixtures without concentration adjustment (MA-Dil). SCIT-related AdR were self-reported in 313 (33%) administrations, 97% at the injection site and 11% grade 1 systemic symptoms. In a multivariable model, being a female and having asthma were associated with higher risk of AdR. MA-NoDil SCIT presented a lower risk of AdR compared to SA-SC SCIT. Conclusions. SCIT-related AdR were self-reported in 1/3 of the administrations, most at the injection site. The risk of AdR was higher in females and in patients with asthma. The lower risk of adverse reactions observed in SCIT preparations with multiple allergens with no dilutional effect should be further explored in future, targeted studies.

The use of remote care during the Coronavirus disease 2019 pandemic: a perspective of Portuguese and Spanish physicians.

Summary: This study aimed to characterise how the follow-up of outpatients was done during the first months of COVID-19 pandemic by a multidisciplinary group of physicians involved in an asthma mHealth project. A cross-sectional study based on a web survey was conducted. The survey was sent to 123 physicians working at secondary care centres of Portugal and Spain, that participate in the INSPIRERS project. A total of 65 physicians completed the survey (53% response rate). They had a mean of 18 (11) years of clinical practice and 14% were residents. More than half were allergists (58%), 22% pulmonologists and 20% paediatricians. Most were working in Portugal (89%) and in public hospitals (88%). All were conducting consultations: 71% presential (median [p25 , p75] duration 30 [20, 30] min), 91% telephonic (15 [10, 20] min) and 20% video consultations (20 [10, 28] min). The median duration of presential consultations was significantly higher than pre-COVID-19 (20 [20, 30] min; p = 0.021). From the physicians conducting video consultations, 92% were allergists and only 54% considered that their institution provided adequate conditions. The physicians of the INSPIRERS group used telephonic consultations as the main alternative to presential ones and 1/5 used video consultations. These results suggest the need to rethink clinical follow-up services for outpatients in the near future increasing the use of telemedicine, especially video consultations.

Prescribing patterns of medication for respiratory diseases: cluster analysis of the Portuguese electronic prescription database.

Summary: We aimed to describe, for the first time, the prescribing patterns among patients on persistent respiratory treatment, from the Portuguese electronic prescription and dispensing database. This was a one-year retrospective population-based analysis of prescriptions (n = 39810) for medication for respiratory disease and exacerbations. Cluster analysis was applied based on medication and prescribers' specialty. Prescribing patterns were grouped and labelled as: possible medication for asthma and allergic rhinitis (General Practitioners-GPs and allergists to younger patients); COPD (GPs and pulmonologists to older patients); asthma or Asthma-COPD Overlap (GPs and pulmonologists); exacerbation, infection and relievers. This analysis was an important first step to understand the Portuguese reality on the treatment of respiratory diseases.

Opinions of patients with persistent asthma regarding the use of mobile applications for disease monitoring.

SUMMARY: Background.We assessed adherence to treatment and management needs of adults with persistent asthma and their interest in using apps for asthma management. Secondarily, we explored opinions of patients about an app to assess and improve adherence to treatment. Methods. A cross-sectional study was conducted with 40 adults with persistent asthma (49.9 ± 15.8 years) recruited at outpatient clinics from a district hospital. Participants answered a survey on sociodemographic, asthma control, treatment adherence and use of mobile devices, social networks and apps. Four patients participated in a prospective extension of the study, in which they were invited to use the InspirerMundi app. Results. 48 percent of the participants had at least greater-equal than 1 exacerbation in the previous year and 85 percent had uncontrolled asthma. Self-reported adherence to treatment showed that one in four participants had low adherence. At least daily, 55 percent of participants navigated on the internet with their smartphone-tablet, 35 percent used apps and 93 percent social networks. Nine (22 percent) participants had previously used health-fitness apps and 65 percent would like to use apps to improve inhaler adherence. Conclusions. Most participants had uncontrolled asthma, reported high adherence to treatment and were daily users of social networks and the internet. Only 1/4 used apps but 2/3 would like to use apps to support asthma management.
