Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cytotoxicity may involve inhibition of peroxisome proliferator-activated receptor alpha. Fenofibrate activates peroxisome proliferator-activated receptor alpha and inhibits SARS-CoV-2 replication in vitro. Whether fenofibrate can be used to treat coronavirus disease 2019 (COVID-19) infection in humans remains unknown. Here, we randomly assigned inpatients and outpatients with COVID-19 within 14 d of symptom onset to 145 mg of oral fenofibrate nanocrystal formulation versus placebo for 10 d, in a double-blinded fashion. The primary endpoint was a severity score whereby participants were ranked across hierarchical tiers incorporating time to death, mechanical ventilation duration, oxygenation, hospitalization and symptom severity and duration. In total, 701 participants were randomized to fenofibrate (n = 351) or placebo (n = 350). The mean age of participants was 49 ± 16 years, 330 (47%) were female, mean body mass index was 28 ± 6 kg/m

Introduction: Patients with the SARS-CoV2 virus are hospitalized for pneumonia and acute respiratory failure. Hypercoagulability, micro and macro thrombosis appear in them. The severe increase in D-dimer has led to the use of thromboprophylaxis with doses higher than the standard with controversial results. The present article aims to guide the physician in a rational thromboprophylaxis to reduce thrombotic complications and avoid bleeding associated with anticoagulation and underlying disease. The results of randomized controlled clinical trials for optimal management of the hypercoagulable state are awaited. Introducción: Los pacientes infectados por el virus SARS-CoV2 son hospitalizados por neumonía e insuficiencia respiratoria aguda. En ellos aparecen hipercoagulabilidad, micro y macro trombosis. El severo incremento del dímero D ha llevado al uso de tromboprofilaxis con dosis mayores a la estándar con resultados controversiales. El presente artículo tiene el objetivo de orientar al médico en una tromboprofilaxis racional para reducir las complicaciones trombóticas y evitar las hemorragias asociadas a la anticoagulación y a la enfermedad de fondo. Se esperan los resultados de los ensayos clínicos controlados aleatorizados para el manejo óptimo del estado hipercoagulable.
