Objective: To determine whether the guidelines put forth in the III Brazilian Consensus on Asthma Management are being applied in a population of asthma patients treated at a public hospital that is a referral center for asthma in the city of Porto Alegre, Brazil. Methods: All adult asthma patients who began their treatment between 1999 and 2002 were evaluated. The treatment given was classified as consistent or inconsistent with the Consensus guidelines. The clinical features of asthma and the frequency of treatment provided by a specialist were compared between the two groups (those receiving guideline-consistent treatment and those receiving guideline-inconsistent treatment). Results: The charts of 357 patients were evaluated. The study sample consisted of 106 males (29.9%) and 251 females (70.3%). The mean age was 41 years, and 33 (9.2%) of the patients were smokers. The treatment was considered inconsistent with the Consensus guidelines in 246 cases (70%). Of those 246, 174 (71%) had presented persistent asthma and were not treated with an inhaled corticosteroid. Normal forced expiratory volume in one second, being from 12 to 18 years of age, and having intermittent asthma were more frequently observed among the patients receiving guideline-consistent treatment (p < 0.01). No correlations were found between guideline-inconsistent treatment and being treated by a pulmonologist, severity of persistent asthma or number of emergency room visits. Conclusion: Most of the asthma patients treated at the public referral center in Porto Alegre did not receive treatment that was consistent with the Consensus guidelines. Undertreatment with inhaled corticosteroids was the principal source of that inconsistency.

Acceptability, preference, tolerance and clinical efficacy of dipropionate beclomethasone delivered by two inhalation devices in chronic asthma patients: Clenil pulvinal versus Miflasona Aerolizer Background: Approximately half of all asthmatic patients adhere to their prescribed treatment regimen, which makes noncompliance with treatment one of the main problems associated with the disease. It is possible that inhalation devices combining technological advances with comfort and simplicity of use could increase treatment compliance. Objective: To compare the acceptability of and preference for two inhalation devices (Pulvinal and Aerolizer), as well as to evaluate the efficacy of and tolerance for beclomethasone dipropionate when delivered by these two systems. Method: A multicenter, randomized, crossover parallel study was carried out involving 83 patients with stable asthma. Patients received 500-1000 g/day of beclomethasone dipropionate. After a 2-week run in, the patients were randomized to begin a 4-week crossover treatment period with equivalent doses of Clenil Pulvinal (CP) or Miflasona Aerolizer (MA). Results: Both groups showed improvement in dyspnea and FEV1, and acceptability was considered good or excellent in both groups. Of the patients studied, 50.6% preferred CP, and 39% preferred MA. In their future treatment regimes, 54.5% would choose the CP and 37.7% the MA. Conclusion: Clinical efficacy and acceptability were comparable between CP and MA.
