Abstract

Objectives: The current study aims to assess the efficacy and safety of Enoxaparin and hydroxychloroquine (HCQ) used as monothrapy or polytherapy versus standard care alone in Coronavirus 2019 (COVID-19) infected patients.

Methods: The current study included two hundred patients with laboratory confirmed COVID-19 infection. Patients admitted to hospital were randomly allocated into four groups: group I: received standard COVID-19 therapy, group II: received Enoxaparin 40mg/day subcutaneously (SC) plus standard therapy, group III: received 400 mg/day HCQ plus standard therapy & group IV: received a combination of 400 mg/day HCQ and Enoxaparin plus standard COVID-19 therapy. The disease progression was evaluated by duration to a negative polymerase chain reaction (PCR), length of hospital or Intensive Care Unit (ICU) stay, and mortality rate. The safety of treatments was evaluated by measuring adverse effects.

Results: The length of hospital stay, ICU admission and mortality were significantly decreased in Enoxaparin plus standard COVID-19 therapy group versus other groups.

Conclusion: These findings suggest that Enoxaparin was safe, effective, and well tolerated and has a role in decreasing the progression of the disease and its complications while HCQ did not discover any evidence of extra therapeutic benefits.
