Associations of Fatty Liver Disease with Hypertension, Diabetes, and Dyslipidemia: Comparison between Alcoholic and Nonalcoholic Steatohepatitis.

Alcoholic steatohepatitis (ASH) and nonalcoholic steatohepatitis (NASH) are representative types of fatty liver disease (FLD) and have similar histologic features. In this study, we aimed to compare the associations of the two FLD types with hypertension (HT), diabetes mellitus (DM), and dyslipidemia (DL). A nationwide survey investigating FLD status included 753 Japanese subjects (median age 55 years; male 440, female 313) with biopsy-proven ASH (n = 172) or NASH (n = 581). We performed a multiple logistic regression analysis to identify the factors associated with HT, DM, or DL. Older age and a higher body mass index were significant factors associated with HT. Older age, female sex, a higher body mass index, advanced liver fibrosis, and the NASH type of FLD (odds ratio 2.77; 95% confidence interval 1.78-4.31; P < 0.0001) were significant factors associated with DM. Finally, the NASH type of FLD (odds ratio 4.05; 95% confidence interval 2.63-6.24; P < 0.0001) was the only significant factor associated with DL. Thus, the associations of NASH with DM and DL were stronger than those of ASH with DM and DL. In the management of FLD subjects, controlling DM and DL is particularly important for NASH subjects.
