Title: Non-alcoholic fatty liver disease in pediatric type 2 diabetes: Metabolic and histologic characteristics in 38 subjects.
Abstract: BACKGROUND: Obesity and type 2 diabetes (T2D) is risk factors for non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). In children with T2D and liver biopsies, we investigated correlations between NAFLD/NASH and transaminase activity, A1c, lipids, and histologic changes in repeat biopsies. METHODS: Liver histology of children with T2D was evaluated using the NASH CRN scoring system and NAFLD Activity Score (NAS). We included results &#8804;6&#8201;months from biopsy and A1c nearest biopsy. RESULTS: Thirty-eight subjects (21 females, 17 males, 63.2% Hispanic, 15.8% Caucasian) had T2D diagnosed at 13.4&#8201;&#177;&#8201;2.7&#8201;years, 78.9% using metformin and 50% on insulin. Histological diagnosis of NAFLD occurred at mean age 14.3&#8201;&#177;&#8201;2.3 years, notable for NASH in 61%. Steatosis grade was higher in children with NASH than those without (mean 2.6&#8201;&#177;&#8201;0.7 vs 2.1&#8201;&#177;&#8201;0.5 (P&#8201;<&#8201;0.001). Stage 3 fibrosis was noted only in subjects with NASH (26%). ALT was higher in NASH vs those without (112&#8201;&#177;&#8201;56 vs 85&#8201;&#177;&#8201;112, P&#8201;=&#8201;0.016). NAS correlated with A1c (r&#8201;=&#8201;0.51, P&#8201;<&#8201;0.01) and triglycerides (r&#8201;=&#8201;0.5, P&#8201;<&#8201;0.01), and inversely with high-density lipoprotein (HDL) (r&#8201;=&#8201;-0.42, P&#8201;=&#8201;0.04). Males had lower HDL and higher triglycerides (P&#8201;<&#8201;0.04). In eight subjects with repeat biopsies, NAS was equal (37.5%) or improved (62.5%), and steatosis decreased (68.1% to 32.8%, P&#8201;=&#8201;0.027). CONCLUSIONS: In children with T2D and NAFLD, NASH is common. Having advanced fibrosis in 26% of NASH cases at this age is concerning. Better control of lipids, weight, and diabetes may help avoid worsening in NAS.
