The role of bronchoscopy in patients with SARS-CoV-2 pneumonia.

BACKGROUND: The role of bronchoscopy in coronavirus disease 2019 (COVID-19) is a matter of debate. PATIENTS AND METHODS: This observational multicentre study aimed to analyse the prognostic impact of bronchoscopic findings in a consecutive cohort of patients with suspected or confirmed COVID-19. Patients were enrolled at 17 hospitals from February to June 2020. Predictors of in-hospital mortality were assessed by multivariate logistic regression. RESULTS: A total of 1027 bronchoscopies were performed in 515 patients (age 61.5±11.2 years; 73% men), stratified into a clinical suspicion cohort (n=30) and a COVID-19 confirmed cohort (n=485). In the clinical suspicion cohort, the diagnostic yield was 36.7%. In the COVID-19 confirmed cohort, bronchoscopies were predominantly performed in the intensive care unit (n=961; 96.4%) and major indications were: difficult mechanical ventilation (43.7%), mucus plugs (39%) and persistence of radiological infiltrates (23.4%). 147 bronchoscopies were performed to rule out superinfection, and diagnostic yield was 42.9%. There were abnormalities in 91.6% of bronchoscopies, the most frequent being mucus secretions (82.4%), haematic secretions (17.7%), mucus plugs (17.6%), and diffuse mucosal hyperaemia (11.4%). The independent predictors of in-hospital mortality were: older age (OR 1.06; p<0.001), mucus plugs as indication for bronchoscopy (OR 1.60; p=0.041), absence of mucosal hyperaemia (OR 0.49; p=0.041) and the presence of haematic secretions (OR 1.79; p=0.032). CONCLUSION: Bronchoscopy may be indicated in carefully selected patients with COVID-19 to rule out superinfection and solve complications related to mechanical ventilation. The presence of haematic secretions in the distal bronchial tract may be considered a poor prognostic feature in COVID-19.

Perfil de pacientes que abandonan un programa de rehabilitación respiratoria / Patient Profile of Drop-Outs From a Pulmonary Rehabilitation Program

Introducción: Aunque los beneficios de los programas de rehabilitación respiratoria (RR) en pacientes EPOC han sido demostrados, la adherencia es baja, relacionándose con peores resultados. Objetivo: Identificar las causas de abandono de un programa de RR para EPOC y las características de los pacientes con mala adherencia, haciendo especial énfasis en características funcionales y clínicas. Método: Estudio prospectivo en 83 EPOC desde febrero a noviembre de 2015. Se realizó un programa mixto (fuerza y resistencia) ambulatorio de 36 sesiones. Se facilitó la accesibilidad con ambulancias. Los pacientes fueron divididos en adherentes (acudieron al menos al 70% del programa) o no adherentes (al menos a una sesión). Resultados: Se evaluaron 83 pacientes, de los que 26 fueron excluidos. Un 15,7% rehusó participar. La tasa de abandono fue del 38,5%. Las principales causas fueron tener baja motivación para acudir al gimnasio y problemas de trasporte. El grupo que abandonó el programa presentó una menor capacidad vital forzada (abandonan 58,9% vs. completan 67,8%; p = 0,03), peores resultados en el test de esfuerzo submáximo (abandonan 6,2 min vs. completan 9,2 min; p = 0,02), en W totales (abandonan 42,6 vs completan 56,5; p = 0,03) y en VO2, tanto en ml/min/kg (abandonan 11,4 vs completan 13,6; p = 0,03) como en ml/min (abandonan 839 vs completan 1.020; p = 0,04). Este grupo también presentó mayor uso de esteroides orales (abandonan 23,8% vs completan 2,9%; p = 0,01). Conclusiones: Más de 1/3 de los pacientes abandonan los programas. Las causas principales son relativas a la motivación y el transporte. El perfil de paciente que abandona presenta peores pruebas funcionales, más exacerbaciones, uso de esteroides y tabaquismo

Introduction: While the benefits of pulmonary rehabilitation programs (PR) in COPD have been demonstrated, poor adherence, related with worse clinical outcomes, is common. Objective: The purpose of this study was to examine causes for drop-out during a 12-week multidisciplinary pulmonary rehabilitation program and to investigate the characteristics of patients with poor adherence, with special emphasis on functional and clinical characteristics. Method: A prospective study was performed between February and November 2015 in 83 COPD patients enrolled in an outpatient program of 36 strength +resistance training sessions. Ambulances were provided to facilitate access to the clinic. Patients were divided into: adherent (A) (attended at least 70% of the program) or non-adherent (NA) (at least one session). Results: A total of 83 patients were evaluated and 26 excluded; 15.7% refused to participate. The drop-out rate was 38.5%. The main causes were low motivation and transport problems. Lower forced vital capacity (NA, 58.9% vs A, 67.8%; P = .03), worse results on submaximal exercise test (NA, 6.2 minutes vs A, 9.2 minutes; P = .02), in total distance walked (NA, 42.6 vs A, 56.5; P = .03) and VO2 in ml/min/kg (NA, 11.4 vs A, 13.6; P = .03) and in ml/min (NA, 839 vs A, 1020; P = .04) were found in the non-adherent group. This group also showed higher use of oral steroids (NA, 23.8% vs A, 2.9%; P = .01). Conclusions: More than 1/3 of patients leave programs. The main causes are related to motivation and transport. The patients who dropout are those with worse functional tests, more exacerbations, steroids and smoking habit
