[Incidence and characteristics of adult-onset asthma]. / Incidencia y características del asma bronquial de inicio en la edad adulta.

OBJECTIVE: To determine the incidence of adult-onset asthma, along with lung function and immunologic characteristics, causes, and clinical course of the disease. PATIENTS AND METHODS: After identifying incident cases of asthma among adult residents of the district of North Barcelona, Spain, we proceeded to characterize the disease using a questionnaire, lung function tests, and skin allergy tests. Patients with an occupation associated with asthma, wheezing at work, and/or sensitization to workplace allergens were considered as having occupational asthma. The risk factors for developing chronic asthma were determined by multivariate analysis. RESULTS: In the 2-year study period, 218 incident cases of adult-onset asthma were identified (in a population of 68 067 adults, corresponding to an annual incidence of 160 per 100 000 per year). In total, 152 patients agreed to participate in the study (response rate, 70%); 140 reported wheezing and/or asthma in the last year (92%). The skin tests showed atopy in 57 cases (41%). Occupational asthma was diagnosed in 19 cases (14%). Domestic mammals were identified as causal agents in 8 patients (6%), drugs in 7 (5%), and environmental allergens in 44 (31%). Household cleaning was the occupation most frequently associated with the disease (26%). Of the 102 patients examined again after 2 years, 70 had chronic asthma (69%). Atopy (odds ratio [OR], 3.39; 95% confidence interval [CI], 1.15-9.99) and risk occupation when the disease was diagnosed (OR, 5.54; 95% CI, 1.05-29.11) were the factors associated with development of chronic disease. CONCLUSIONS: Occupation was related to adult-onset asthma in a little over 10% of the cases and was the main determinant of the development of chronic symptoms.

Prevalence of smoking in a psychiatric hospital and its relationship with respiratory symptoms and the prevalence of COPD.

Purpose: Psychiatric patients present an elevated rate of smoking, and the smoking habit is related to a high morbidity and mortality in this collective. The aim of this study was to determine the prevalence of smoking in patients admitted for psychiatric disorders and its relationship with respiratory disease, the prevalence of COPD, and alterations in the quality of life. Patients and methods: A cross-sectional, observational study was conducted and detailed information on smoking and respiratory symptomatology was obtained. The study participants underwent the following tests: spirometry with bronchodilator test, Fagerström test, determination of physical activity using the LCADL questionnaire, and evaluation of quality of life with the EuroQoL-5 Dimensions EQ-5D questionnaire. Results: Two hundred seventy-six patients (mean age 56.8 years) were included: 155 with schizophrenia (87.7% smokers), 46 with depressive or anxiety disorders (54.3% smokers), and 49 and 25 with intellectual disability and dementia (43.2% smokers), respectively. The mean Fagerström test score was 5.75 points. Smokers presented with cough (47.6%), expectoration (41.4%), and chronic bronchitis (36.6%). The prevalence of COPD in the total population was 28.9%. The EQ-5D and LCADL scores were better in smokers because of their younger age and lesser psychiatric involvement. A high prevalence of smoking was observed in the psychiatric population studied, and 28.9% were diagnosed with COPD. Conclusion: Smokers presented many more respiratory symptoms and chronic bronchitis but did not present a worse quality of life or physical activity due to their younger age and milder psychiatric involvement.

Incidencia y características del asma bronquial de inicio en la edad adulta / Incidence and characteristics of adult-onset asthma

OBJETIVO: Determinar la incidencia del asma del adulto, junto con las características funcionales e inmunológicas de la enfermedad, sus causas y su evolución. PACIENTES Y MÉTODOS: Tras la identificación de los habitantes de Barcelona Norte con un primer diagnóstico de asma del adulto, se procedió a la caracterización de la enfermedad por cuestionario, función respiratoria y pruebas cutáneas de alergia. Los pacientes con una ocupación causante de asma, sibilancias durante el trabajo y/o sensibilización a un alérgeno laboral se consideraron afectados de asma relacionada con la ocupación. Los factores de riesgo de cronificación del asma se determinaron por medio de análisis multivariante. RESULTADOS: En 2 años se identificaron 218 primeros diagnósticos de asma del adulto (población: 68.067 adultos; incidencia anual: 160/100.000). Aceptaron participar en el estudio 152 pacientes (índice de respuesta: 70%), de los que se caracterizó a 140 que referían sibilancias y/o asma bronquial en el último año (92%). Las pruebas cutáneas mostraron atopia en 57 casos (41%). Se diagnosticó asma relacionada con la ocupación en 19 casos (14%), por mamíferos domésticos en 8 (6%), por fármacos en 7 (5%) y por alérgenos ambientales en 44 (31%), siendo la limpieza doméstica la ocupación más frecuentemente asociada a la enfermedad (26%). De los 102 pacientes examinados de nuevo a los 2 años, 70 presentaban asma crónica (69%); la atopia (odds ratio [OR] = 3,39; intervalo de confianza [IC] del 95%, 1,15-9,99) y una ocupación de riesgo cuando se diagnosticó la enfermedad (OR = 5,54; IC del 95%, 1,05-29,11) fueron los factores de cronificación del asma. CONCLUSIONES: La ocupación del paciente está relacionada con el asma del adulto en algo más de una décima parte de los casos y es un determinante principal de la cronicidad de sus síntomas
