Randomized Phase 3 Trial of Ruxolitinib for COVID-19-Associated Acute Respiratory Distress Syndrome.

Objectives: Evaluate the safety and efficacy of the Janus kinase (JAK)1/JAK2 inhibitor ruxolitinib in COVID-19-associated acute respiratory distress syndrome requiring mechanical ventilation.

Design: Phase 3 randomized, double-blind, placebo-controlled trial Ruxolitinib in Participants With COVID-19-Associated Acute Respiratory Distress Syndrome Who Require Mechanical Ventilation (RUXCOVID-DEVENT; NCT04377620).

Setting: Hospitals and community-based private or group practices in the United States (29 sites) and Russia (4 sites).

Prevalence of pulmonary hypertension in end-stage cystic fibrosis and correlation with survival.

Background: Limited information is available about the prevalence of pulmonary hypertension diagnosed by right heart catheterization (RHC) in patients with cystic fibrosis being evaluated for lung transplantation. It is unclear whether there are factors that can predict the presence of pulmonary hypertension and whether the presence of pulmonary hypertension influences patient outcomes.

Methods: The study included 57 unique and consecutive adult patients (33 women) with cystic fibrosis who underwent lung transplant evaluation at the University of Florida.
