Objective: To determine the frequency of near-fatal asthma in a group of severe asthma patients, as well as the clinical characteristics and prognosis of these patients within a one-year follow-up period. Methods: A prospective study involving 731 low-income patients with severe asthma treated at a referral outpatient clinic located in the city of Salvador, Brazil. The patients were submitted to spirometry at admission, received medications for asthma, and were monitored regarding the frequency of asthma exacerbations during the follow-up period. A subsample of 511 patients also completed questionnaires regarding asthma symptoms and asthma-related quality of life. Results: Of the 731 patients studied, 563 (77%) were female. The median age was 47 years, and 12% were illiterate. Most of the patients had rhinitis, and 70 patients (10%) reported near-fatal asthma prior to admission. Of these 70 patients, 41 (59%) reported having been intubated previously. The patients reporting a history of near-fatal asthma at admission were more likely to have asthma exacerbations during the follow-up period and to respond poorly to therapy than were those not reporting such a history. At the end of the follow-up period, the scores on the two questionnaires were similar between the two groups of patients. Conclusions: The frequency of near-fatal asthma was high in this group of low-income patients with severe asthma. The patients with a history of near-fatal asthma had a worse prognosis than did those without such a history, although both groups had received the same kind of treatment. Curiously, the intensity of symptoms and the quality of life at the end of the study were similar between the two groups.

INTRODUCTION: Cystic Fibrosis is usually diagnosed in childhood. In Brazil, few studies have approached CF diagnosed in adulthood. OBJECTIVE:The aim of this study was to describe demographic and clinical characteristics and spirometric data of patients with CF diagnosed in adulthood (over 16 years of age) in Bahia, Brazil. METHODS: Twenty-eight patients with cystic fibrosis diagnosed in adulthood were evaluated at the Reference Center of Cystic Fibrosis of the state of Bahia. Variables of interest were age, gender, race, body mass index (BMI), sputum culture, presence of sinusitis and bronchiectasis, spirometric tests with the best values performed for forced expiratory volume in the first second (FEV1), forced vital capacity (FVC) and response to bronchodilators. RESULTS: Mean age of diagnosis was 31.1 ± 12.4 years. Of the patients, 53.4% were black and mulatto and the mean BMI was 18.7 ± 3.0 kg/m2. P aeruginosa was present in 12 (43%) of the total patients. The mean percentages ± SD of FVC and FEV1 were 58.9 ± 21.6% and 44.1 ± 23%, respectively. In the group of patients with presence of P. aeruginosa in sputum cultures, mean of the spirometry parameters were lower than those of the P. aeruginosa-free group. However, this difference achieved a statistically significant difference (p = 0.0007) only in FVC . CONCLUSIONS: In agreement with many authors, this study strengthen the point of view that CF must be investigated in patients with recurrent infections, sinusitis and bronchiectasis even in adulthood. Values of the percentages of FVC and FEV1 in relation to those foreseen were lower in patients bearers of P. aeruginosa thereby showing a higher deterioration of the pulmonary function.
