Boston Hospitals To Test Cystic Fibrosis Drug On Severely Ill Coronavirus Patients
BOSTON (CBS) — Harvard University researchers are working with two Boston hospitals to try a new way to help the sickest coronavirus patients. Boston Children’s Hospital and Brigham and Women’s Hospital will test a drug approved by the FDA to treat people with cystic fibrosis on those experiencing severe COVID-19 pneumonia and respiratory failure. The drug is called Dornase alfa, also known as DNase 1 or Pulmozyme, and it works to prevent lung infections by breaking up thick mucus. That may make oxygen easier to deliver via ventilator, researchers say. There’s also hope that the drug might break up neutrophil extracellular traps or NETs, which the researchers say could be contributing to lung inflammation. A neutrophil, blue, releases unwound DNA, the backbone of NETs. The dots show proteins modified during NET formation or released by neutrophils and bound to NETs.

The goal of the 18-month randomized, controlled study is to find out how many patients are alive and off a ventilator after 28 days. It aims to enroll 60 adults and children who need mechanical ventilation. ...
Authors: Rombauts A, Abelenda-Alonso G, Cuervo G, Gudiol C, Carratalà J Abstract INTRODUCTION: Despite adequate antibiotic coverage, community-acquired pneumonia (CAP) remains a leading cause of hospitalization and mortality worldwide. It induces both a local pulmonary and a systemic inflammatory response, particularly significant in severe cases. The intensity of the dysregulated host response varies from patient to patient and has a negative impact on survival and other outcomes. AREAS COVERED: This comprehensive review summarizes the pathophysiological aspects of the inflammatory response in CAP, brie...

CONCLUSIONS: This single practice study showed total patient contact was similar over both sample periods, but most contact in 2020 was virtual. Further longitudinal multi-practice studies to confirm these findings and describe future consultation patterns are needed to inform general practice service delivery post-COVID-19.

AbstractObjectivesSevere Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) may trigger severe pneumonia in coronavirus disease of 2019 (COVID-19) patients through release of damage-associated molecular patterns (DAMPs) and recruitment of neutrophils in the lungs. Activated neutrophils induce inflammation and severe alveolar injury by releasing neutrophil extracellular traps (NETs). The backbones of many DAMPs and NETs are made of extracellular, cell-free DNA decorated with highly toxic compounds such as elastase, myeloperoxidase and citrullinated histones. Dornase alfa is a FDA-approved recombinant human DNAse 1 for th...
She had trouble breathing, and the E.R. doctors discovered a mass in her lung. Was this cancer — or something a little more unusual?
A cluster of cases of pneumonia of unknown origin presented in Wuhan, China in early December 2019; the cause was subsequently found to be a novel coronavirus, now named SARS-Cov-2 . This new virus is highly transmissible and has resulted in a pandemic with over 2 million confirmed infections and more than 145,000 deaths in humans in 185 countries .
