AbstractAimType 2 diabetes (T2DM) is closely related to nonalcoholic fatty liver disease (NAFLD) and is an important risk factor for the progression of liver fibrosis, but the role of 2-h postprandial blood glucose (PPG) as a biomarker in this process remains unclear. This study was designed to investigate the relationship between PPG and liver fibrosis in Chinese NAFLD populations with or without T2DM.
MethodsThis study included three independent NAFLD populations:1) 618 inpatients with T2DM or pre-diabetes, 2) 255 patients with T2DM or pre-diabetes who underwent liver biopsy, and 3) a prospective community-based cohort without diabetes who completed a median of 4.22 years follow-up. The degree of liver fibrosis was assessed by liver fibrosis stage in subjects with a liver biopsy, and by NAFLD fibrosis score (NFS) in subjects without liver biopsy.
ResultsIn the first population, PPG was positively correlated with NFS. In the second population, an increasing PPG was associated with increase in the proportion of advanced liver fibrosis (P = 0.012). Multivariate line regression revealed that PPG was positively associated with liver fibrosis stages. In the third population, PPG at baseline was positively associated with NFS at follow-up. Furthermore, changes in PPG were significantly associated with NFS change after follow-up. We did not find a similar association between fasting glucose or HbA1c and liver fibrosis.
ConclusionsPPG was independently associated with the severity of liver fibrosis in the Chinese NAFLD population.
