Abstract:

Objective

To explore the causal relationship between liver cirrhosis and osteoporosis.

Methods

The aggregate data of genome-wide association study (GWAS) were analyzed. Taking liver cirrhosis as exposure factor, single nucleotide polymorphism (SNP) as instrumental variable, and osteoporosis as outcome variable. MR-Egger method, weighted median method, inverse variance weighted (IVW) method, simple model method and weighted model method were used for Mendelian randomized analysis, and the sensitivity analysis was carried out by heterogeneity test, multiplicity test and retention test.

Results

A total of 7 SNP was included as tool variables. The results of IVW analysis showed that there was a causal relationship between liver cirrhosis and osteoporosis, and liver cirrhosis increased the incidence of osteoporosis (β=0.090, OR=1.095, 95%CI: 1.025-1.169, P < 0.01); weighted median analysis also showed that liver cirrhosis increased the risk of osteoporosis (β=0.094, OR=1.099, 95%CI:1.012-1.194, P < 0.05). Other methods also suggest that liver cirrhosis can increase the risk of osteoporosis, and the causal effects of the five methods are in the same direction. The results of heterogeneity test showed that there was no heterogeneity among all SNPs. MR-Egger regression showed that there was no horizontal polymorphism of genes. The results of leaving one method showed that the results were robust.

Conclusion

There may be a causal relationship between liver cirrhosis and osteoporosis, and liver cirrhosis may increase the incidence of osteoporosis.
