Abstract
Background
Substantial observational evidence suggests an association between neuropsychiatric conditions and venous thromboembolism (VTE). However, the causal relationship between these two conditions requires further investigation. Therefore, we used a two-sample Mendelian randomization (MR) approach to assess the bidirectional causal effects between four neuropsychiatric conditions and VTE, deep vein thrombosis, and pulmonary embolism (PE).
Methods
Genetic variants associated with four neuropsychiatric conditions (ie, schizophrenia, major depressive disorder [MDD], bipolar disorder, and epilepsy) and VTE, deep vein thrombosis, and PE were selected. Bidirectional univariable and multivariable MR methods were applied to evaluate the causal relationships among these conditions. The primary causal estimates were obtained using the inverse variance weighted method with multiplicative random effects, supplemented by MR Egger regression, weighted median, simple mode, and weighted mode. Sensitivity analysis was conducted using the MR pleiotropy residual sum, funnel plots, and outlier (MR pleiotropy and residual sum and outlier) method.
Results
Univariable MR results showed that genetic susceptibility to MDD increases the risk of VTE and PE (VTE: odds ratio [OR], 1.25; 95% confidence interval [CI], 1.08-1.46; P = .004; PE: OR, 1.36; 95% CI, 1.09-1.69; P = .006) and that PE has an adverse causal effect on MDD (OR, 1.02; 95% CI, 1.00-1.04; P = .026). Adjustment for confounders such as obesity, sleep duration, smoking, physical activity, and alcohol consumption revealed that increased genetic susceptibility to MDD is also associated with VTE and PE.
Conclusions
Our results suggest that genetic susceptibility to MDD might have an adverse causal effect on the risk of VTE and PE and that PE has a reverse causal effect on MDD. Prevention and early diagnosis of depression are crucial in the management of VTE and PE.
期刊介绍:
Journal of Vascular Surgery: Venous and Lymphatic Disorders is one of a series of specialist journals launched by the Journal of Vascular Surgery. It aims to be the premier international Journal of medical, endovascular and surgical management of venous and lymphatic disorders. It publishes high quality clinical, research, case reports, techniques, and practice manuscripts related to all aspects of venous and lymphatic disorders, including malformations and wound care, with an emphasis on the practicing clinician. The journal seeks to provide novel and timely information to vascular surgeons, interventionalists, phlebologists, wound care specialists, and allied health professionals who treat patients presenting with vascular and lymphatic disorders. As the official publication of The Society for Vascular Surgery and the American Venous Forum, the Journal will publish, after peer review, selected papers presented at the annual meeting of these organizations and affiliated vascular societies, as well as original articles from members and non-members.
