Negative impacts of the administration of hydroxycloroquine and anticoagulant in patients with SARS-COV-2 infection: a randomized clinical trial

Abstract

Purpose: To evaluate antimalarial with or without anticoagulant treatment, in patients with recent SARS-COV-2 infection. Methods: Clinical study carried out at Samuel Libânio Clinic Hospital, University of Vale do Sapucaí, Pouso Alegre-MG. Approved by the Ethics Committee (4.034.077) and registered in the Clinical Trials (NCT04788355). Suspected patients for COVID-19 were included in the emergency room. The groups were: C (control) with 6 patients, A (anticoagulant apixaban) with 9 patients, H (hydroxychloroquine) with 5 patients and HA (hydroxychloroquine and anticoagulant apixaban) with 8 patients. Results: there were no significant differences between groups. The HA group, in which there was an intervention with two drugs, presented a greater number of days with symptoms (p = 0.037) and worse results, when compared to the control: most relevant symptoms, were: cough (p = 0.001), and anosmia / ageusia (p = 0.011) headache (p = 0.001). Conclusion: The present study began when there were doubts about the use of drugs such as Hydroxychloroquine (HCQ) and apixaban (APX). The reduced “n” was defined through bureaucratic and polemic issues independent of the authors’ actions. No clinical benefit was associated with HCQ and APX. There was an increase in the number of symptomatic days when HCQ and APX were administered. Despite the limitations, there was no therapeutic indication of the evaluated drugs.
