“…While the pathological mechanisms in many of the non-CF forms of BE are often unclear, their clinical course is similar [11]. Patients develop chronic cough with purulent sputum, dyspnoea, and haemoptysis [12, 13]. Haemoptysis occurs in 20–37% of the patients with BE [14, 15].…”

Background: There is no study on the predictive factors of recurrent haemoptysis after bronchial artery embolization (BAE) with the long-term outcomes in patients with bronchiectasis (BE). Objectives: To evaluate the long-term outcomes of BAE in BE patients without accompanying refractory active infection of mycobacteriosis and aspergillosis with analysis for the predictive factors of recurrent haemoptysis. Methods: Data of 106 patients with BE who underwent BAE using coils between January 2011 and December 2018 were retrospectively reviewed. The cumulative haemoptysis control rate was estimated using Kaplan-Meier methods with log-rank tests to analyze differences in recurrence-free rate between groups based on technical success and failure, bacterial colonization status, number of BE lesions, and vessels embolized to bronchial arteries (BAs) or BAs + non-bronchial systemic arteries (NBSAs). Results: Bacterial colonization was detected in approximately 60% of patients. Computed tomography showed bronchiectatic lesions with 2.9 ± 1.4 lobes. In the first series of BAE, embolization was performed in the BAs alone and BAs + NBSAs in 65.1 and 34.9% of patients, respectively, with 2.4 ± 1.4 embolized vessels in total. The median follow-up period was 1,000 (7–2,790) days. The cumulative haemoptysis control rates were 91.3, 84.2, 81.5, and 78.9% at 1, 2, 3, and 5 years, respectively. The haemoptysis control rates were higher in the technical success group than in the technical failure group (p = 0.029). Conclusions: High haemoptysis control rates for long-term periods were obtained by embolization for all visualized abnormal arteries, regardless of the colonization status, number of bronchiectatic lobes, and target vessels, irrespective of NBSAs.

Recommendations for travelling with bronchiectasis: a joint ELF/EMBARC/ERN-Lung collaboration

et al. 2019

IntroductionPeople with bronchiectasis frequently request specialist advice to prepare for travelling, but there are few publications providing advice on safe travel with bronchiectasis. There is a need for recommendations on adapting everyday treatment to the requirements during travelling.MethodsA panel of 13 patient volunteers formulated questions regarding different aspects of travelling, including safety of travel, maintaining regular treatment during travel, and dealing with deterioration while away. Patient input was used to derive a questionnaire and circulated among a panel of bronchiectasis experts. Where 80% or more experts agreed on a response, a recommendation was made.ResultsA total of 26 bronchiectasis experts answered the questionnaire. Recommendations were made on safety of travel, choice of destinations and activities, choice of travel insurance, carrying medications and devices, maintaining regular treatments in transport, documentation to be provided and oxygen requirements. Some statements did not reach an 80% agreement; in many cases these statements may be valid for some, but not all bronchiectasis patients.ConclusionsThe general agreement was that it is considered safe for most people with bronchiectasis to travel. Careful planning and preparation with robust communication between patients and their healthcare provider prior to travel for different scenarios is fundamental to a successful journey.

“…According Wang et al [25], concentrations of SO 2 and other pollutants such as CO and NO 2 appeared to have positive effect on hospitalizations, especially at high concentrations, for instance by bronchiectasis. Also other authors [ 41 ] reported that only sulfur dioxide was associated with out-patient visits.…”

BackgroundThis work describes the changes of the air quality and the health implications caused by the lockdown of the first-wave provoked by the SARS-CoV-2 pandemic. Air pollutants were studied in 83 locations in Southern Spain. The study covered urban and industrial gases, NO2, CO, SO2, H2S and O3, and also PM10 and PM2.5 particles.MethodsIt was evaluated the increase and decrease of concentrations during the state of alarm declared on 14th March. Pearson correlations for air pollutants, meteorological factors, vehicular traffic densities (VTDs) and data of infections and deaths caused by the COVID-19 disease were also assessed.ResultsIt was found a clear reduction in carbon monoxide (-25% to -83%), particulate matter (-21% to -42%) and mainly nitrogen dioxide (-55% to -81%) in trafficked areas during the lockdown, reducing cardiovascular and respiratory problems. CO, SO2 and H2S increased (+26 to 34%, +68 to +85% and +32 to +84%) at industrial locations. O3 increased along the lockdown period coinciding with reductions in NO2 and CO (r = -0.90 and -0.81). This ozone rising constitute the ozone lockdown effect (OLE), increasing the risk of pneumonia hospital admissions. Regarding traffic, Pearson coefficients between ozone and VTDs were higher during lockdown than pre-lockdown period, and in the most trafficked areas a reduction in PM10 and PM2.5 levels was observed, contributing this also to the OLE.ConclusionsEffects of ozone on COVID-19 disease was revealed by the graphic associations and correlations found between O3 levels and infection cases and deaths, which were remarkable, constituting in this case the ozone COVID effect (OCE): when concentrations of O3 increase, the incidence of the disease is higher; when O3 falls, infection cases are reduced.
