Abstract

Objective: The goal of this study was to examine whether metabolic abnormalities are responsible for the histological changes observed in Japanese patients with nonalcoholic fatty liver disease (NAFLD) who have undergone serial liver biopsies.

Research design and methods: In total, 39 patients had undergone consecutive liver biopsies. Changes in their clinical data were analyzed, and biopsy specimens were scored histologically for stage.

Results: The median follow-up time was 2.4 years (range 1.0-8.5). Liver fibrosis had improved in 12 patients (30.7%), progressed in 11 patients (28.2%), and remained unchanged in 16 patients (41%). In a Cox proportional hazard model, decrease in A1C and use of insulin were associated with improvement of liver fibrosis independent of age, sex, and BMI. However, DeltaA1C was more strongly associated with the improvement of liver fibrosis than use of insulin after adjustment for each other (chi(2); 7.97 vs. 4.58, respectively).

Conclusions: Tight glycemic control may prevent histological progression in Japanese patients with NAFLD.
