Abstract:
Objective: This study aimed to explore the causal association between genetically predicted medication use and sepsis. Methods: Utilizing summary data from genome-wide association studies (GWAS) on selected medications use and sepsis, a two-sample Mendelian randomization (MR) design was employed. Analysis was conducted using the Inverse Variance Weighted (IVW), weighted median, weighted mode, and MR-Egger regression methods. Sensitivity analysis included MR-Egger, MR-PRESSO, Cochran's Q, and leave-one-out methods. Results: The IVW method suggested that genetically predicted medication use, including Drugs used in diabetes (OR = 1.08, 95%CI: 1.02-1.15, P = 0.015), diuretics (OR = 1.08, 95%CI: 1.01-1.15, P = 0.034), thyroid preparations (OR = 1.08, 95%CI: 1.03-1.13, P = 0.001), and adrenergics (OR = 1.09, 95%CI: 1.01-1.18, P = 0.037), might be causally associated with a higher risk of sepsis. Datasets for drugs in diabetes, antithrombotic agents, renin-angiotensin system agents, anilides, and glucocorticoids may exhibit heterogeneity. MR-Egger regression results indicated minimal influence of horizontal pleiotropy on all associations except possibly for antithrombotic agents and sepsis. MR-PRESSO test found no outliers. Leave-one-out analysis confirmed associations were not driven by any single factor. After removing confounders, the IVW method suggested that genetically predicted diuretics use (OR = 1.17, 95%CI: 1.03-1.34, P = 0.018) might be causally associated with a higher risk of sepsis, while drugs used in diabetes, thyroid preparations, and inhaled adrenergics were not. No heterogeneity was observed. MR-Egger regression results indicated the minimal influence of horizontal pleiotropy on all associations. MR-PRESSO test found no outliers. Leave-one-out analysis confirmed any single factor did not drive associations. Conclusions: This study found that prior use of diuretics may increase sepsis risk, with inconclusive evidence for other medications.
Insights
Genetically predicted diuretic use may increase sepsis risk. Evidence for other medications, including diabetes drugs and thyroid preparations, was inconclusive in this Mendelian randomization study.
Area of Science:
- Pharmacogenomics
- Infectious Disease Epidemiology
Background:
- Sepsis is a life-threatening condition with significant morbidity and mortality.
- Understanding the influence of prior medication use on sepsis risk is crucial for prevention and treatment strategies.
Purpose of the Study:
- To investigate the potential causal relationship between genetically predicted medication use and the risk of developing sepsis.
- To differentiate between potential associations and causal links using robust genetic methods.
Main Methods:
- Employed a two-sample Mendelian randomization (MR) design using summary data from genome-wide association studies (GWAS).
- Utilized Inverse Variance Weighted (IVW), weighted median, and MR-Egger regression methods for primary analysis.
- Conducted sensitivity analyses including MR-Egger, MR-PRESSO, Cochran's Q, and leave-one-out methods to assess robustness and rule out pleiotropy.
Main Results:
- Initial analysis suggested potential causal links between genetically predicted use of diuretics, drugs used in diabetes, thyroid preparations, and adrenergics with increased sepsis risk.
- After adjusting for confounders, only genetically predicted diuretic use remained significantly associated with a higher risk of sepsis (OR = 1.17, P = 0.018).
- Sensitivity analyses indicated minimal evidence of horizontal pleiotropy or heterogeneity influencing the association between diuretic use and sepsis.
Conclusions:
- Prior use of diuretics may causally increase the risk of sepsis.
- Evidence for a causal association between the use of other investigated medications (e.g., diabetes drugs, thyroid preparations) and sepsis risk was not supported by this study.
- The findings highlight diuretics as a potential factor influencing sepsis risk, warranting further clinical investigation.
