Integrating Mendelian randomization, machine learning and retrospective clinical data: an exploratory analysis of the cross-disease association between CHB and PD, with a focus on eosinophil alterations
Clinical Report: Investigating Chronic Hepatitis B and Parkinson's Disease
Overview
This study employs a multifaceted approach to explore the relationship between chronic hepatitis B (CHB) and Parkinson's disease (PD), revealing a genetically predicted inverse association between CHB susceptibility and PD risk. Key findings include the identification of specific genes and metabolic pathways that may link these conditions.
Background
Chronic hepatitis B (CHB) affects approximately 254 million people globally and poses significant public health challenges. Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder, with projections indicating a substantial increase in cases by 2050. Understanding the potential link between CHB and PD is critical due to the inconsistent findings in previous epidemiological studies.
Data Highlights
The study utilized two-sample Mendelian randomization, revealing an odds ratio (OR) of 0.82–0.94 (p < 0.05) for the inverse association between CHB susceptibility and PD risk. Additionally, eosinophil levels were found to be inversely correlated with these conditions (OR = 8.99, p < 0.001).
Key Findings
Mendelian randomization indicates a genetically predicted inverse association between CHB susceptibility and PD risk.
RTN3 and MAP4K3 identified as priority cross-disease genes linking CHB and PD.
Phenylalanine metabolism shows dysregulated patterns between CHB and PD.
Eosinophil levels decline in CHB but rise in PD.
Immune infiltration analysis supports the involvement of eosinophils in the correlation between CHB and PD.
Clinical Implications
The findings indicate a genetically predicted inverse association between CHB susceptibility and PD risk.
Conclusion
This study provides evidence of an inverse relationship between chronic hepatitis B and Parkinson's disease.
