Steroid-Induced Thrombosis: Comprehensive Analysis Through Use of the FAERS Database

Background/Objectives: Thrombosis, a critical condition that can have severe conse-quences, such as myocardial infarction and cerebral infarction, can be induced by steroid drugs. Although the mechanisms for inducing thrombosis are known for some types of steroid drugs, much remains unknown about the differences in the tendency and mecha-nisms for thrombosis. Methods: To address this knowledge gap, we analyzed the rela-tionship between thrombosis and steroid use by utilizing the U.S. Food and Drug Admin-istration (FDA) Adverse Event Reporting System (FAERS) database. From the database, we extracted demographic and drug information and information on reported adverse events from 2004 to 2024. We characterized drugs according to physiological function, receptor specificity, and Anatomic Therapeutic Chemical classification and calculated the propor-tion of steroid drugs that were likely to induce thrombosis. Results: Among steroid drugs, sex hormones such as androgens, progestogens, and estrogens appeared to have particu-larly high potential for causing thrombotic events. Results of principal component analy-sis and cluster analysis indicated that sex hormone preparations were associated with an increased risk of venous thrombosis. In addition, cardiovascular medications and miner-alocorticoids, which are used to treat diseases of major organs, showed a tendency to in-duce large-vessel occlusions. Conclusions: These findings may be useful for selecting ster-oid drugs for patients who are at risk for similar adverse effects.
