Abstract
UNLABELLED: Nonalcoholic fatty liver disease (NAFLD) is highly prevalent and associated with decreased quality of life (QOL). The currently available treatment is weight loss through lifestyle modification. However, longitudinal QOL data are lacking on whether weight loss improves QOL. We prospectively enrolled 151 patients with NAFLD from 2009 to 2014. All patients received a liver biopsy, lifestyle assessment, blood tests, and QOL tools, including the Chronic Liver Disease Questionnaire (CLDQ), a validated health-related quality of life measurement. All patients were followed with a repeat CLDQ at 6 months. The cohort included 91 (60%) men, ages 51.5 ± 12.6 years, 46 (30%) of whom were diabetic. Thirty (21%) had advanced fibrosis or cirrhosis and 67 (47%) had a NAFLD Activity Score >4. Overall, 47 (31%) patients achieved at least a 5% reduction in weight. The cohort's median baseline total CLDQ value was 5.6 (interquartile range: 4.8-6.2). Those who achieved at least a 5% reduction in weight had a 0.45 (95% confidence interval [CI]: 0.24-0.66; P < 0.0001) point improvement in the total CLDQ, compared to 0.003 (95% CI: -0.12-0.12; P = 0.95) in those who did not. Nondiabetic patients with nonalcoholic steatohepatitis and without advanced fibrosis are most likely to achieve QOL benefits from weight loss. For every decrement in body mass index (BMI), there was a corresponding increase of 0.09 (95% CI: 0.03-0.16) points in the CLDQ scale (P = 0.005), adjusting for histology, diabetes, sex, age, and change in alanine aminotransferase level and change in FIB-4 index. A decrease by 5 points in BMI leads to a 10% adjusted improvement in QOL. CONCLUSION: Patients with NAFLD can experience significant improvements in QOL that appear specific to weight loss and not biochemical improvements.
