title: [A multicenter, open-label, randomized comparison of suppressive effects on asthmatic inflammation of lower airways and improved effects on health-related QOL between HFA-BDP and fluticasone propionate].
abstract: OBJECTIVE
  It is important to evaluate the effects of hydrofluoroalkane-beclomethasone dipropionate (HFA-BDP), which shows predominant deposition in the lower airways, on asthmatic inflammation in the lower airways and the Quality of Life (QOL) of asthma patients, as compared with those of fluticasone propionate (FP) Diskus.
  
  
  METHODS
  Seventy-seven adult patients with mild persistent or more severe asthma who were being treated with FP for >/=3 months were randomly assigned to the HFA-BDP group and continued FP group. The differential count of eosinophils in the peripheral blood, the serum cortisol levels, and pulmonary function parameters were measured before the study and at 3 months after the start of the study treatment. The improvements in the Asthma Quality of Life Questionnaire (AQLQ) scores were also compared. Sputum samples collected by the induced expectoration method (inhalation of 10% saline for 15 min) were divided into the early-phase sputum samples obtained within 15 minutes of the inhalation and the late-phase sputum samples obtained later than 15 minutes after the inhalation, and the eosinophil count and eosinophil cationic protein (ECP) levels were measured.
  
  
  RESULTS
  In the HFA-BDP group (N=40), the differential count of eosinophils in the peripheral blood was significantly decreased as compared with that in the FP group (p=0.009), and the scores in all the domains of the AQLQ and the percentage improvement of the total score were significantly better as compared with those in FP group (p=0.033). The eosinophil count in the late-phase sputum samples (p=0.022) as well as the ECP level in the sputum samples showed more pronounced decreases in the HFA-BDP group as compared with those in the FP group. On the other hand, no significant changes were detected in the pulmonary function values.
  
  
  CONCLUSIONS
  Use of the HFA-BDP preparation can more effectively suppress residual inflammation in the lower airways and significantly improve the QOL as compared with use of the FP preparation of asthma patients. Examination of induced sputum samples allows detection of changes in the peripheral airways that cannot be detected by pulmonary function testing.
