Menopausal Hormone Therapy and Progression of Non-Alcoholic Fatty Liver Disease in Postmenopausal Women: A 12-Month Study

ABSTRACT

Objective@#This study was conducted to evaluate the effects of menopausal hormone therapy (MHT) on the progression of non-alcoholic fatty liver disease (NAFLD) in postmenopausal women. @*Materials and Methods@#We included 515 women who received MHT for 12 months. Changes in NAFLD was evaluated by ultrasonography (progressiono progression) were compared before and after 12 months of MHT based on the route of estrogen administration (transdermal/oral). In addition, changes in NAFLD according to estrogen dose and type of progestogen were evaluated. @*Results@#Baseline characteristics did not differ between patients who received transdermal (n=82) vs. oral (n=433) MHT. After 12 months of transdermal MHT, the prevalence of NAFLD decreased from 23.2% to 18.3% and the progression of NAFLD was observed in 3.7% patients, but this was not significantly different from those taking oral MHT. NAFLD progression was more common in women who had NAFLD at baseline and who received on oral MHT regimen compared to transdermal regimen (12.4% vs. 5.3%), however, differences were not statistically significant. In the oral MHT group, progression of NAFLD was significantly more common in standard-dose than low-dose (P=0.039). There was no significant difference in NAFLD progression according to the type of progestogen in patients using standard dose of estrogen. @*Conclusion@#Our findings suggest that the route of estrogen administration and oral dose of estrogen might affect progression of NAFLD in women with NAFLD at baseline.
