1 Streptokinase Versus Unfractionated Heparin Nebulization in Patients With Severe Acute Respiratory Distress Syndrome (ARDS): A Partially Randomized Controlled Trial

Background: Intra-alveolar clotting and alveolar collapse in ARDS is due to alveolar capillaries epithelial and leakage. Subsequently, collapse induces hypoxemia that is resistant to recruitment (RM). Heparin and Streptokinase may prevent or dissolve intra-alveolar fibrin clot respectively helping alveolar re-expansion. We examined and compared the effect of nebulizing Heparin versus Streptokinase on reversing this pathology. Methods: Sixty severe ARDS (PaO2/FiO2<100) patients and failure of RM, prone position (PP) and neuromuscular block (NMB) were partially randomised into Group (I): (n=20) received nebulized Heparin 10000 IU/4h. Group (II): (n=20) received nebulized Streptokinase 250,000 IU/4h. Group (III): (n=20) received conservative management. Randomization to either Heparin or Streptokinase groups was applied to patients whom guardian accepted participation, while those who declined participation were followed-up as a control. The primary outcome was the change in PaO2/FiO2; the secondary outcomes included the change in compliance, plateau pressure, ventilation-off days, coagulation and ICU mortality.

2 InterMediate ProphylACtic Versus Therapeutic Dose Anticoagulation in Critically Ill Patients With COVID-19: A Prospective Randomized Study (The IMPACT Trial)

The purpose of this study is to determine if therapeutic dose anticoagulation (experimental group) improves 30-day mortality in participants with COVID-19 compared to those patients receiving the intermediate dose prophylaxis (control group). Following screening, subjects will be randomized 1:1 to intermediate dose prophylaxis or therapeutic dose anticoagulation treatment arms.Treatment will continue for 28 days, followed by a 6 month follow-up period.
