Efficacy and safety of anticoagulant therapy in patients with chronic cirrhosis complicated with portal vein thrombosis: what should we expert from a meta-analysis?

Yalin LiuJie Li


Background: Systematic review and meta-analysis were performed to evaluate efficacy and safety of anticoagulant therapy in patients with chronic cirrhosis complicated with portal vein thrombosis (PVT). Methods: The PubMed, The Cochrane Library and Web of Science databases were searched. The odds ratio (OR) and risks ratio(RR) with 95% CI was pooled to calculate the difference in the rate of portal vein recanalization and occurrence of bleeding events between patients who received anticoagulation and those who did not. All meta-analysis were conducted by using a random-effects model. Results: 8 studies with a total of 559 patients published between 2005 and 2019 were finally enrolled in our meta-analysis . The rate of portal vein recanalization was significantly higher with PVT who received anticoagulation and those who did not (OR = 4.689, 95% (95% CI = 3.274–6.716, P=0.000). And the pooled risk ratio of bleeding between the two groups was 0.828 (95% CI = 0.511–1.343, P=0.444). The heterogeneity was not statistically significant among studies, Begg’s funnel plot and Egger’s linear regression test were performed to evaluate publicantion bias. Conclusion: Anticoagulation therapy can significantly improve the recanalization rate o...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
