Filter by:Lung involvement in Sjögren's syndrome is common and causes reduced quality of life and increased mortality. Sjögren's syndrome-related lung diseases (SS-RLD) are classified and treated as the primary lung diseases they resemble. Whether this approach is optimal has not been evaluated thoroughly. A critical gap in knowledge is knowing whether SS-RLDs have a unique clinical course and response to therapy. Given the underlying immune system dysfunction in Sjögren's syndrome, the investigators hypothesize that patients with SS-RLD will be more likely to respond to immunosuppressive therapy than patients with the matching primary lung disease. To address this hypothesis, the investigators will prospectively screen for Sjogren's syndrome in patients presenting to pulmonary clinics and compare the clinical course and response to therapy in Sjogren's syndrome positive and negative patients.
This is a randomized, open-label, controlled, Phase II proof of concept study to evaluate the safety, tolerability and efficacy of S-1226 in which hospitalized subjects (n≤30) with moderate severity COVID-19 Bronchiolitis/Pneumonia will be enrolled. The safety and tolerability of S-1226 composed of PFOB with ascending doses of carbon dioxide (4%, 8%, and 12% CO2) administered twice daily will be assessed subjects in hospitalized subjects with moderate severity COVID-19 Bronchiolitis/Pneumonia.
The investigators propose an open label, non-blinded, single center randomized controlled feasibility study to find the optimal initial HFNC flow rate in children less than 12 months old with clinically diagnosed moderate to severe bronchiolitis. This feasibility study is projected over December 2020 to April 2023. The study is consisted of 3 arms, comparing HFNC therapy at 1 L/kg/min, 1.5 L/kg/min, and 2 L/kg/min (20 L/min max). Moderate to severe bronchiolitis is defined clinician's assessment for the need for ICU level of care. The primary outcome is treatment response to HFNC therapy defined by RDAI/Respiratory Assessment Change Score (RACS) ≥ 4 at 4 hours of therapy. Secondary outcome measures comprise of treatment failure requiring an escalation of care during the first 24 hours of HFNC therapy, duration of HFNC and simple nasal cannula therapy, duration of simple nasal cannula therapy, hospital and PICU length of stay (LOS), time to treatment failure, and adverse events.
