Abstract
AbstractThe impacts of patatin‐like phospholipase domain‐containing protein 3 (PNPLA3) I148M‐rs738409, methylenetetrahydrofolate reductase (MTHFR) Ala222Val‐rs1801133, and aldehyde dehydrogenase 2 (ALDH2) Glu504Lys‐rs671 on the outcomes of Taiwanese patients with steatotic liver disease (SLD) have remained elusive. An 8‐year prospective cohort study of patients with (n = 546) and without (n = 580) SLD (controls) was undertaken in a Taiwanese tertiary care center. The 546 SLD patients comprised 306 (56.0%) men and 240 (44.0%) women with mean ages of 53.3 and 56.4 years, respectively. Compared with the controls, SLD patients had an increased frequency of the PNPLA3 I148M‐rs738409 GG genotype (25.5 vs. 5.9%, p = 0.001). Among the SLD patients, 236 (43.1%) suffered cardiovascular events, 52 (9.5%) showed extrahepatic cancers, 13 (2.38%) experienced hepatic events, including hepatocellular carcinoma (n = 3, 0.5%) and liver cirrhosis (n = 8, 1.47%), and none died. The Fibrosis‐4 (FIB‐4) scores were associated with extrahepatic cancer (hazard ratio [HR] 1.325; 95% confidence interval [CI], 1.038–1.691) and cirrhosis development (HR 1.532; 95% CI, 1.055–2.224), and the PNPLA3 I148M‐rs738409 G allele (β = 0.158, 95% CI, 0.054–0.325) was associated with the FIB‐4 score. Stratified analyses showed that the impact of the FIB‐4 score on extrahepatic cancer development was evident only in SLD patients with the PNPLA3 I148M‐rs738409 GG genotype (HR 1.543; 95% CI, 1.195–1.993) and not in patients with the GC or CC genotype. Moreover, the ALDH2 Glu504Lys‐rs671 G allele had a dose‐dependent effect on alcoholism, and the MTHFR and ALDH2 genotypes were not significantly associated with SLD patient outcomes. In conclusion, special vigilance should be exercised for emerging extrahepatic cancer in SLD patients with the PNPLA3 I148M‐rs738409 GG genotype and high FIB‐4 scores.
