Assessing the causal relationship between psoriasis vulgaris and urolithiasis: A two-sample Mendelian randomization...

Area of Science:

• Genetics and Epidemiology
• Dermatology and Urology

Background:

• Observational studies suggest an association between psoriasis and urolithiasis.
• Previous evidence is limited in establishing a causal relationship.

Purpose of the Study:

• To evaluate the causal association between psoriasis vulgaris and urolithiasis.
• Utilizing a robust 2-sample Mendelian Randomization (MR) approach.

Main Methods:

• Employed 2-sample Mendelian Randomization (MR) analysis.
• Utilized genome-wide association study (GWAS) data for psoriasis vulgaris and urolithiasis.
• Applied inverse-variance weighted (IVW), MR-Egger, and weighted median methods for analysis.

Main Results:

• Inverse-variance weighted (IVW) analysis revealed a significant causal association (OR=1.073, P=0.010).
• Consistent results were observed with weighted median and MR-Egger regression analyses.
• Statistical tests indicated no significant heterogeneity or pleiotropy, supporting result validity.

Conclusions:

• This Mendelian Randomization study provides evidence for a causal relationship between psoriasis vulgaris and urolithiasis.
• Findings suggest psoriasis vulgaris may be a causal risk factor for urolithiasis.
