Abstract
Objective: Severe acute respiratory syndrome (SARS) coronavirus 2 (SaRS-Cov-2) associated respiratory disease (COVID-19), announced as a pandemic, is a multisystem syndrome. SARS-CoV-2 directly infects and damages vascular endothelial cells, which leads to microvascular dysfunction and promotes a procoagulant state. Dipyridamole (DP) acts as a reversible phosphodiesterase inhibitor and is used mainly as an antiplatelet agent. It is hypothetised that it has possible activities in COVID-19.
Design and methodology: We report our retrospective, real-world results of DP added to low-molecular weight heparin (LMWH) in the treatment of 462 clinically diagnosed and hospitalized COVID-19 patients. We compared anticoagulation with and without DP addition with no administration of anticoagulation in the same time frame. The primary outcome was proven or highly suspected coagulopathy within 30 days of hospitalization.
Results: Definitive coagulopathy has been diagnosed in 3 (3.5%) of 85 LMWH administered patients and 7 (2.13%) of 328 DP + LMWH received patients (P=0.456). Five cases with definitive coagulopathy were not initiated any anticoagulation at the time of the event. The multivariate analysis showed that DP addition to the anticoagulant approach did not have any impact on the risk of demonstrated coagulopathy and highly-suspected coagulopathy.
Conclusion: We think that our clinical experience is valuable in showing the real-life results of DP + LMWH treatment in COVID-19. This approach did not affect the coagulopathy rate. Our data did also not document an additive effect of DP in the COVID-19 outcome. Prospective controlled trials would give more convincing results regarding the role of DP in COVID-19 endothelial dysfunction and clinical outcome.
