Emerging drugs for the treatment of idiopathic pulmonary fibrosis: 2020 phase II clinical trials

Introduction The enthusiasm generated by the approval of pirfenidone and nintedanib as the first effective therapies for IPF led the IPF scientific community to investigate an increasing number of novel agents in well-designed randomized controlled trials, in the hope to find a cure for these patients. Areas covered This reviews the evidence from IPF phase II trials that were completed or started in 2020. Literature search was performed using Medline and Clinicaltrials.org databases. Expert opinion Randomized clinical trials revolutionized the management of IPF, leading to the discovery of the first therapies capable of slowing down functional deterioration in these patients. The recently published findings of the first successful phase II trials since pirfenidone and nintedanib will hopefully inaugurate a new era in the therapeutic scenario of IPF, where consolidated treatments of proven efficacy and novel targeted agents contribute together to reach the final goal of halting the fibrotic process of this dreadful disease

Residual respiratory impairment after COVID-19 pneumonia

Abstract Introduction: The novel coronavirus SARS-Cov-2 can infect the respiratory tract causing a spectrum of disease varying from mild to fatal pneumonia, and known as COVID-19. Ongoing clinical research is assessing the potential for long-term respiratory sequelae in these patients. We assessed the respiratory function in a cohort of patients after recovering from SARS-Cov-2 infection, stratified according to PaO2/FiO2 (p/F) values. Method: Approximately one month after hospital discharge, 86 COVID-19 patients underwent physical examination, arterial blood gas (ABG) analysis, pulmonary function tests (PFTs), and six-minute walk test (6MWT). Patients were also asked to quantify the severity of dyspnoea and cough before, during, and after hospitalization using a visual analogic scale (VAS). Seventy-six subjects with ABG during hospitalization were stratified in three groups according to their worst p/F values: above 300 (n = 38), between 200 and 300 (n = 30) and below 200 (n = 20). Results: On PFTs, lung volumes were overall preserved yet, mean percent predicted residual volume was slightly reduced (74.8 ± 18.1%). Percent predicted diffusing capacity for carbon monoxide (DLCO) was also mildly reduced (77.2 ± 16.5%). Patients reported residual breathlessness at the time of the visit (VAS 19.8, p < 0.001). Patients with p/F below 200 during hospitalization had lower percent predicted forced vital capacity (p = 0.005), lower percent predicted total lung capacity (p = 0.012), lower DLCO (p < 0.001) and shorter 6MWT distance (p = 0.004) than patients with higher p/F. Conclusion: Approximately one month after hospital discharge, patients with COVID-19 can have residual respiratory impairment, including lower exercise tolerance. The extent of this impairment seems to correlate with the severity of respiratory failure during hospitalization
