Multicenter StudyThe association between treatment with heparin and survival in patients with Covid-19.
This study investigates the association between the treatment with heparin and mortality in patients admitted with Covid-19. Routinely recorded, clinical data, up to the 24th of April 2020, from the 2075 patients with Covid-19, admitted in 17 hospitals in Spain between the 1st of March and the 20th of April 2020 were used. The following variables were extracted for this study: age, gender, temperature, and saturation of oxygen on admission, treatment with heparin, hydroxychloroquine, azithromycin, steroids, tocilizumab, a combination of lopinavir with ritonavir, and oseltamivir, together with data on mortality. ⋯ This association remained significant when saturation of oxygen < 90%, and temperature > 37 °C were added to de model with OR 0.54 (0.36-0.82) p = 0.003, and also when all the other drugs were included as covariates OR 0.42 (0.26-0.66) p < 0.001. The association between heparin and lower mortality observed in this study can be acknowledged by clinicians in hospitals and in the community. Randomized controlled trials to assess the causal effects of heparin in different therapeutic regimes are required.

Comparative Study Observational StudyDirect oral anticoagulants and warfarin in patients with cirrhosis: a comparison of outcomes.
Anticoagulation management in patients with cirrhosis presents several challenges as a result of alterations in hemostasis. Historically vitamin k antagonists and low molecular weight heparins have been the agents of choice in this patient population. Direct oral anticoagulants (DOACs) may provide an alternative to traditional anticoagulant therapy. ⋯ No difference in the rate of stroke or recurrent embolic event at 90 days was identified between the two groups (0% vs. 1.58% p = 0.341; 1.8% vs. 1.8% p = 0.731). In conclusion DOACs appear to be a safe alternative to warfarin in patients with mild to moderate cirrhosis. Further studies are warranted to confirm these findings.
