This Issue collates the abstracts presented at the 25th Biennial International Congress on Thrombosis held on 23–26 May 2018. Prevention and treatment of thromboembolic events is a main issue in medicine that involves all the components of the health care system. Recently, a strong boost in this field came from the introduction of new antithrombotic agents whose use is expanding with the need for more information obtained by real-life studies. Thus, ICT 2018 was an important venue to compare clinical experiences and learn new advances in basic and pharmacological sciences. Full article

Inherited thrombophilias are a group of clinical conditions in which there is a genetic variant defect associated with a predisposition to thrombosis. Genetic testing for inherited thrombophilias has been used in the diagnosis of specific thrombophila at our centre for the last 20 years, this work will summarize our experience. Full article

At the moment, there is no oral thrombolytic drug on the world pharmaceutical market. The drug Trombovazim, which has a thrombolytic effect under oral administration, has been registered in Russia. It differs from all thrombolytics—it has a fundamentally different mechanism of action. It is not an activator of plasminogen. It independently dissolves a thrombus. It is a direct thrombolytic. The article presents the materials of the initial studies of the drug Trombovazim. Full article

Helicobacter pylori (H. pylori) and immune thrombocytopenia (ITP) association is well known and eradication treatment has its place in both treatment guidelines. Since H. pylori eradication is followed by an increase in platelet counts in patients with immune thrombocytopenia, it is suggested that H. pylori be examined and treated if infection is present. There is only one study that demonstrated a relation between H. pylori and platelet indices in individuals with normal platelet counts. In this study, we aimed to investigate the effects of H. pylori infection on platelet count and mean platelet volume, which is a sign of increased platelet destruction in patients with normal platelet counts. We evaluated the data of 106 patients with urease test positivity before the eradication of bacteria and urea breath test negative after the eradication, in a retrospective manner. Mean platelet count in patients before the eradication treatment was 256.730 ± 66.380/mm³. After H. pylori was eradicated, it has been observed that the mean platelet count increased to 287.080 ± 59.240/mm³. Mean MPV of patients before and after eradication treatment were 9.35 ± 1.63 fL and 8.61 ± 1.48 fL. Mean MPV was higher when patients were infected with H. pylori. This study showed that there is an increase in platelet counts and a decrease in MPV levels with the eradication of the H. pylori. Our study is the first to investigate changes of mean platelet volume and platelet count before and after eradication of H. pylori infection in individuals with normal platelet counts. Full article

Unprovoked venous thromboembolism is associated with a 5 to 27% annual risk of recurrence after discontinuation of anticoagulation, and indefinite anticoagulation is recommended if the bleeding risk is low to moderate. However, in one-third of patients with unprovoked venous thromboembolism, the risk of recurrence is so low (<5% per year) that anticoagulant therapy >3–6 months may not be necessary. Several prediction rules were derived to identify patients with unprovoked venous thromboembolism who have a low recurrence risk. In 2016, we presented our results of the original DAMOVES, a nomogram for prediction of recurrence in an individual patient with unprovoked venous thromboembolism. The aim of this study was to externally validate this nomogram in patients with unprovoked venous thromboembolism. Full article
