1261-P: Prevalence of Nonalcoholic Fatty Liver Disease and Liver Fibrosis in Patients with Type 1 Diabetes

Abstract

Nonalcoholic fatty liver disease (NAFLD) is a common comorbid condition in patients with type 2 diabetes. However, little is known about its prevalence among patients with type 1 diabetes (T1D). We used transient elastography to measure controlled attenuation parameter (CAP) as steatosis indicator and liver stiffness measurement (LSM) as fibrosis indicator. We evaluated 537 patients with T1D: age 49±16 years; 55% females; 81% non-Hispanic whites; BMI 27.6±5.5 kg/m2; diabetes duration 29±15.6 years; A1C 7.1±1.0%; total daily insulin (TDI) 49±28 U/day; ALT 19±10 IU/L; AST 22±8 IU/L. The prevalence of NAFLD (CAP≥274 dB/m) was 28.5% (95% CI 24.6-32.6) and fibrosis (LSM≥7 kPa) 8.4% (95% CI 6-11). Moreover, 4.1% (95%CI 2.6-6.2) of NAFLD had ≥F2 fibrosis (LSM ≥ 8.2 kPa) suggesting nonalcoholic steatohepatitis (NASH). Higher CAP positively correlated with higher BMI (p<0.001); diabetes duration (p<0.01); and TDI (p<0.001). It was common in males (OR 2.1, 95%CI 1.3-3.5, p<0.01). Among those with NAFLD, mean ALT was 21±11 IU/L (p=0.02), AST 22±7 IU/L, BMI 32.7±5.8 kg/m2, and waist circumference (WC) 103±15 cm. Among those with fibrosis, mean ALT was 23±10 IU/L (p=0.01), AST 24±7 IU/L (p=0.03), BMI 31.7±6.4 kg/m2 and WC 104±15 cm. Obesity (BMI >30 kg/m2) and larger WC (>102 cm in men, >88 cm in women) were associated with increased risk for hepatic steatosis (OR 3.1, 95% CI 1.6-6.0, p=0.001; OR 4.0, 95% CI 2.2-7.5, p<0.001, respectively). In conclusion, prevalence of NAFLD and liver fibrosis is considerable among patients with T1D, while liver enzymes are within normal range. Obesity and large waist circumference are associated with increased risk of hepatic steatosis. Independent predictors of NAFLD include: higher BMI, longer diabetes duration, higher TDI and male gender. Screening for NAFLD and liver fibrosis is advisable for patients with T1D irrespective of their liver enzymes, particularly in patients with higher BMI, longer diabetes duration or among those treated with larger insulin dose.
