cri analog pg1 effectiveness and safety in covid-19

Conditions: Covid19

Summary: the clinical trial aim to evaluate the effectiveness and safety of the administration of the intravenous prostaglandin e1 analog in the reduction of mortality and complications of patients with covid-19 diagnosis. therefore the investigators propose an open randomized clinical trial in the fundación santa fe de bogota

covid-19 is a public health problem that has spread throughout the world and has forced different scientific societies to consider effective measures to control the increasing spread of the disease. this disease is presumed to follow a virologic pattern similar to sars-cov-1 (severe acute respiratory syndrome coronavirus 1) . the disease spectrum includes asymptomatic stage and pre-symptomatic , mild infection uncomplicated, mild and severe pneumonia and the acute respiratory distress syndrome (ards) constituting the point of no return characterized by ventilatory mechanics preserved with severe refractory hypoxemia. the pulmonary involvement of patients with covid-19 causes an endothelial injury, which can be associated with changes in vascular permeability, manifesting as thrombotic, venous and arterial disease in patients with covid-19. alprostadil, a prostaglandin e1 analog that has a vasodilator mechanism, inhibitory property of platelet aggregation and inducer of bronchodilation, promises to prevent complications of sars-cov2. in addition to that alprostadil has been used in other clinical trials as treatment for the acute respiratory distress syndrome caused by influenza, in which it showed no harm or benefit, nonetheless the pathophysiology of the acute distress respiratory syndrome caused by influenza and covid-19 are similar in macroscopic changes but very different in microscopic changes which is why it is important to evaluate the effectiveness and safety of the administration of intravenous prostaglandin e1 analog in the reduction of mortality and complications of patients with covid-19 diagnosis. therefore the investigators propose an open randomized clinical trial, where patients in the intensive care unit of the fundación santa fe de bogotá are randomized into two groups, where one is going to be treated with standardized treatment after the guidelines recommendations of the colombian infectology society and the other one is going to receive the same standardized treatment and alprostadil infusion for a maximum of 7 days. during the infusion of the alprostadil the patient will be carefully monitored by the intensive care unit team. after the infusion the patient will be followed up for 30 days in which the mortality and hypoxemia resolution will be monitored. key words: covid-19, prostaglandin e1 analogue, alprostadil, mortality, acute respiratory distress syndrome
