Interplay between BMI, neutrophil, triglyceride and uric acid: a case-control study and bidirectional multivariate...

Area of Science:

• Metabolic Health
• Inflammation Research
• Genetic Epidemiology

Background:

• Understanding the interplay between body mass index (BMI), neutrophils, triglyceride levels, and uric acid (UA) is crucial for disease prevention.
• Uric acid's association with inflammatory conditions requires further investigation for effective health management.

Purpose of the Study:

• To explore the causal correlations between BMI, neutrophils, triglyceride levels, and uric acid (UA).
• To elucidate the role of inflammatory states as potential mediators in these relationships.

Main Methods:

• Retrospective analysis of 4,286 cases using Spearman correlation.
• Two-sample Mendelian randomization (MR) and multivariable Mendelian randomization (MVMR) leveraging genome-wide association study (GWAS) data.
• Utilized genetic variation to assess causal impacts on uric acid levels.

Main Results:

• Significant associations found between uric acid (UA) and BMI (ρ=0.230), neutrophils (ρ=0.164), and triglyceride levels (ρ=0.154).
• MR analysis confirmed reciprocal causal links between neutrophils and UA, and positive causal connections between UA and BMI/triglycerides.
• Established causal pathways between neutrophils, BMI, triglyceride levels, and UA, indicating a complex interconnected network.

Conclusions:

• Confirmed a complex interconnection between BMI, neutrophils, triglyceride levels, and UA.
• Highlighted inflammatory states as key mediators in the observed causal links.
• Findings contribute to a better understanding of metabolic and inflammatory health, potentially improving clinical outcomes.
