Masitinib, a c-kit and PDGF-receptor tyrosine kinase inhibitor, may represent an innovative avenue of treatment in corticosteroid-dependent asthma. These preliminary results warrant further long-term clinical studies in severe asthma

Rituximab maintenance therapy was well tolerated but did not completely prevent relapses and persistent "grumbling" disease. These preliminary results remain to be confirmed by a randomized controlled trial currently in progress.

BackgroundThe impact of COPD on patient’s quality of life is well established, but gender differences have received little attention.MethodsTo describe factors associated with the health-related quality of life by gender: A cross-sectional observational study (NCT01007734) was conducted in COPD patients followed by pulmonologists. The first patient included had to be a woman. Data concerning the patient, COPD and their management were collected by the physician. The patient had to fill in several questionnaires: Saint-George Hospital respiratory Questionnaire (SGRQ-C), and motivation to quit smoking.ResultsFour hundred and thirty patients were included: mean age 63.9 ± 11.3 years; 57.4% were women. Women were significantly younger than men (61.9 vs. 66.6) and their tobacco use was lower (37.1 vs. 40.4 PY). Cardiovascular comorbidities were more frequent in men while osteoporosis, anxiety and depression were frequent in women. The frequency of cough, sputum and the severity of dyspnea did not differ significantly between genders. Lung function impairment was less severe in women than in men (mean FEV1 52% predicted normal vs. 47. 8%). Anxiety score was higher (score 9.8 vs. 7.1) and quality of life (SGRQ-C) more impaired in women (scores 50.6 vs. 45.4; p < 0.02) than in men. Moreover, in multivariate analysis, chronic sputum was associated with higher SGRQ-C scores in women but not in men.ConclusionsThis study underlines that despite less airflow limitation, quality of life is more impacted by chronic sputum in women than in men.

This study compared the efficacy and safety of the fluticasone propionate 125 microg pressurized metered dose inhaler (pMDI) propelled by either hydrofluoroalkane (HFA) 134a or chlorofluorocarbon (CFC) propellants, in adult patients with asthma. HFA 134a is a non-ozone depleting propellant used as a replacement for the CFC propellants 11 and 12 which are being phased out in accordance with the Montreal Protocol. Three hundred and eighty patients with mild to moderate asthma and 'room for improvement' in their treatment were randomized to receive fluticasone propionate 250 microg twice daily via pMDIs propelled by either CFC propellants 11 and 12 (n = 195) or HFA 134a (n = 185). Fluticasone propionate significantly improved lung function over the 4-week treatment period in both treatment groups. The improvement in mean morning peak expiratory flow (PEF) after 7 days of treatment was approximately 12 l min(-1) in both groups, rising to approximately 22 l min(-1) at the end of the 4-week treatment period. The adjusted mean difference between the two formulations over weeks 1-4 was -1 l min(-1) (90% confidence interval: -7, 5 l min(-1)), confirming their equivalence. Clinical comparability was also demonstrated with respect to secondary efficacy variables, including daily symptom scores, evening PEF and clinic visit expiratory measurements. There were no clinically relevant differences in adverse events or serum cortisol levels between the two groups. The fluticasone propionate 125 microg HFA 134a pMDI is an effective and well tolerated product and is a suitable replacement for the fluticasone propionate 125 microg CFC pMDI at a microgram equivalent dose.
