RESUMEN
Given the existing uncertainty regarding the effectiveness and safety of switching from low-molecular-weight heparin (LMWH) to direct oral anticoagulants (DOACs) in patients with cancer-associated venous thrombosis (CAT), we conducted a comprehensive population-based cohort study utilizing electronic health database in Hong Kong. A total of 4356 patients with CAT between 2010 and 2022 were included, with 1700 (39.0%) patients switching to DOAC treatment. Compared to continuous LMWH treatment, switching to DOACs was associated with a significantly lower risk of hospitalization due to venous thromboembolism (HR: 0.49 [95% CI = 0.35-0.68]) and all-cause mortality (HR: 0.67 [95% CI = 0.61-0.74]), with no significant difference in major bleeding (HR: 1.04 [95% CI = 0.83-1.31]) within six months. These findings provide reassurance regarding the effectiveness and safety of switching from LMWH to DOACs among patients with CAT, including vulnerable patient groups.

Background: P2Y12 inhibitors are an important component of dual antiplatelet therapy. Yet, their accessibility and affordability across countries stratified by income levels have not been studied. Methods: Sales data were retrieved from the IQVIA Multinational Integrated Data Analysis System for the description of P2Y12 inhibitors global sales. Countries were stratified into 38 high-income countries and 27 middle-income countries. Results: Global sales of P2Y12 inhibitors increased from 0.80 SU per year per person in 2008 to 1.79 in 2018. Growth in sales of P2Y12 inhibitors was greater in middle-income countries compared to high-income countries. Clopidogrel had the highest sales volume in both high-income and middle-income countries from 2008 to 2018, while ticagrelor sales volume increased mainly in high-income countries. Conclusions: Despite current guideline recommendations favoring ticagrelor and prasugrel for the prevention of atherothrombotic complications in patients with an acute coronary syndrome, clopidogrel retained the highest sales volume among the P2Y12 inhibitors from 2008 to 2018.
