Treatment response according to small airways disease status: The effects of high-strength extrafine pMDI beclomethasone dipropionate/formoterol fumarate in fixed dose combination in moderate uncontrolled asthmatic patients
Abstract Background Inflammation in small airways is particularly clinically active in severe asthma but they still continue to be ignored as considered silent. Recently, the Atlantis study reports small airways involvement in 91% of the asthma population. Therefore in the era of phenotype driven therapy, the aim of this study was to verify if high-strength extrafine ICS/LABA in fixed dose increases clinical efficacy in moderate asthmatic patients with small airways dysfunction and it could be proposed as phenotype driven therapy. Methods In this prospective, non-interventional, real-life pilot study we enrolled 37 consecutive patients with moderate asthma who were uncontrolled despite GINA step 3 treatment. All subjects at enrollment were divided in two groups according to the presence of small airways dysfunction:1) small airways phenotype (SAP) group: smokers (≥10 packs/die), ex-smokers (>20 packs/year) with air trapping (FVC 100% - FEF 25–75% Results Treatment with extrafine BDP/FF(200/6 μg) in SAP group showed a more significant improvement of FEF25-75%, FVC, RV, and a reduction of alveolar inflammatory markers such as FENO350 and alveolar exhaled pH compared with NSAP patients. Conclusions Our preliminary results support the use of high-strength extrafine pMDI BDP/FF (200/6 μg) as phenotype driven treatment directed to small airways dysfunction demonstrating an increase of clinical efficacy in moderate asthmatics with SAP
Survival of patients with idiopathic pulmonary fibrosis and pulmonary hypertension under therapy with nintedanib or pirfenidone
Idiopathic pulmonary fibrosis (IPF) is a specific form of chronic, progressive, fibrosing interstitial pneumonia of unknown cause that leads to respiratory failure and death within few years of diagnosis. Pulmonary hypertension (PH) is a common complication in IPF, where it is strongly associated with increased morbidity and mortality. Patients with IPF and PH have particularly poor prognosis, despite current best medical therapies and the anti-fibrotic therapy with pirfenidone or nintedanib. The aim of our study was to assess the clinical and prognostic impact of PH in patients affected by IPF, already treated with pirfenidone or nintedanib. Seventy-four consecutive outpatients with a diagnosis of IPF, in therapy with pirfenidone or nintedanib, were prospectively enrolled in the study. All patients underwent pulmonary and cardiology assessment by clinical exam, spirometry, DLCO test, chest CT, 6MWT and echocardiography performed by a cardiologist experienced in PH in an ambulatory setting under resting conditions. GAP index has been determinate for all patients. During follow-up, all patients were evaluated every 6 months, or less if necessary. Data about mortality were then collected in a 3-year follow-up. Of the seventy-four patients enrolled, 38 were treated with pirfenidone and 36 with nintedanib. The two groups were comparable for age, gender, FVC, DLCO and PAPS. The patients were also divided in four groups, based on presence of mild/moderate/severe PH by echocardiography at baseline. Significant differences were found for DLCO and the GAP index. Severity of PH was significantly associated with a reduction of DLCO and with an increased GAP index. Survival was directly correlated with 6MWT (R = 0.48), DLCO (R = 0.29, p < 0.01), and reversely with tGAP index (- 0.31, p < 0.01 in all cases), while no significant correlation was found with PAsP. 36-month survival analysis showed an HR of 4.05 (95% CI 1.07-7.34, p = 0.02) for DLCO < 50% and of 1.56 (95% CI 1.02-2.39, p = 0.03) for GAP index. The development and progression of PH in patients affected by IPF reduce the survival and the severity of PH is associated with a reduction of DLCO value and an increase of the GAP index. Echocardiographic stratification based on PAsP values may be useful in stratifying prognosis in IPF patients and deciding specific PAH drugs
