ABSTRACT
BACKGROUND:
Prior observational studies have suggested a potential direct link between psoriasis (PSO) and interstitial lung disease (ILD). Consequently, we applied Mendelian randomization (MR) to further evaluate the bidirectional causal relationships between PSO and its different phenotypes [psoriatic arthritis (PSA)/psoriasis vulgaris (PSV)] and ILD.METHODS:
Data regarding PSO/PSA/PSV and ILD were sourced from publicly accessible genome-wide association studies (GWAS) databases, focusing on European populations. We used five algorithms- MR Egger, weighted median, inverse-variance weighted (IVW), simple mode, and weighted mode- to evaluate the causal relationships between PSO/PSA/PSV and ILD, with a primary emphasis on the IVW method.RESULTS:
The analysis indicated a potential association between PSA and an elevated risk of ILD [IVW odds ratio (OR) 1.035 (95% CI 1.008, 1.064; P = 0.012)], with no evidence of a direct relationship between total PSO and PSV with ILD. Conversely, no substantial evidence emerged from the reverse MR analysis to suggest that ILD significantly affects total PSO or the specific PSA/PSV phenotypes.CONCLUSION:
Our findings provide genetic evidence supporting the notion that PSA may be a contributory risk factor for ILD. Further investigations are warranted to explore the underlying mechanisms of this potential causal relationship between PSA and ILD.Palavras-chave
