[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.

[Predictive factors for readmission in heart failure patients]. / Morbimortalidad de los pacientes ingresados por insuficiencia cardíaca. Factores predictores de reingreso.

BACKGROUND AND OBJECTIVE: Heart failure (HF) is a prevalent and increasing disease and represents one of the main causes of hospital admission. It is associated with an important morbi-mortality and a high rate of readmission. The objective of this study was to know the clinical characteristics of admitted patients with HF and to detect any valuable prognosis factors. PATIENTS AND METHOD: Prospective study of admitted HF patients between May'99 and May'00. Readmission rate was evaluated six months later. RESULTS: 204 patients were included with an average age of 78 (9.9) years. 66% were women. Diabetes mellitus (DM) (36.4%) and chronic obstructive pulmonary disease (COPD) (23.4%) were the most outstanding associated pathologies. Ischemic heart disease (IHD) was the most frequent etiology in 33.4% cases. Mean time of admission was 10 days. 34% patients had systolic dysfunction (SD). Men with IHD presented a higher rate of SD (p < 0.001). Mortality was 12.4%, especially in COPD patients (p < 0.011). IECAs were prescribed in 71.2% in the SD group. Readmission rate at 6 months was about 43%. Patients with renal failure (p < 0.04) and those with a more impaired functional class (p < 0.02) displayed a higher readmission rate. CONCLUSIONS: Several clinical factors determine the morbi-mortality and prognosis including an older age, associated comorbility, type of cardiopathy and presence of systolic dysfunction. All these factors are detected at the time of hospital admission.

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

Morbimortalidad de los pacientes ingresados por insuficiencia cardíaca: factores predictores de reingreso / Predictive factors for readmission in heart failure patients

FUNDAMENTO Y OBJETIVO: La insuficiencia cardíaca (IC) es una enfermedad de prevalencia creciente que constituye una de las principales causas de hospitalización. Se asocia con una notable morbimortalidad y un elevado índice de reingreso. El objetivo de este estudio es conocer las características clínicas de los pacientes ingresados por IC y detectar factores con valor pronóstico en esta enfermedad. PACIENTES Y MÉTODO: Estudio prospectivo de los pacientes ingresados por IC entre mayo de 1999 y mayo de 2000. A los 6 meses se valoró la tasa de rehospitalización. RESULTADOS: Se incluyeron 204 pacientes con una edad media (DE) de 78 (9,9) años. El 66% eran mujeres. La diabetes (36,4%) y la enfermedad pulmonar obstructiva crónica (EPOC)(23,4%) fueron las enfermedades asociadas más destacadas. La cardiopatía isquémica (CI) fue la etiología más frecuente (33,4%). La estancia media fue de 10 días. Se detectó disfunción sistólica (DS) en el 34%. Los varones y la CI presentaron más DS (p < 0,001). La tasa de fallecimientos fue del 12,4%; los pacientes con EPOC presentaron mayor mortalidad (p < 0,011). Los inhibidores de la enzima conversiva de la angiotensina (IECA) se pautaron en el 71,2% en el grupo con DS. La tasa de reingreso a los 6 meses fue del 43%. Los pacientes con insuficiencia renal (p < 0,04), con IC previa (p < 0,02) y con clase funcional más deteriorada (p < 0,02) tuvieron mayor índice de reingreso. CONCLUSIONES: La edad avanzada, el sexo, la cormorbilidad asociada, el tipo de cardiopatía y la presencia de disfunción sistólica son factores clínicos que determinan el pronóstico de morbimortalidad. Todos ellos son detectables en el momento de la hospitalización
