Abstract

Objective: To investigate the clinical features of non-alcoholic fatty liver disease (NAFLD) and its relationship with serum C-peptide levels in patients with latent autoimmune diabetes in adults (LADA).<br />Methods: A total of 155 patients with LADA who had no drinking history and were hospitalized in department of endocrinology and metabolism from January 2007 to June 2009 were divided into two groups, including patients with LADA but without NAFLD and patients with both LADA and NAFLD, according to Chinese medical association's guidelines of NAFLD and hepatic ultrasound result. Their clinical data and results of laboratory examinations were collected and analyzed, including medications, blood pressure, weight, height, waist circumference, hip circumference, fasting plasma glucose, 2 h postprandial plasma glucose, fasting C-peptide, 2 h postprandial C-peptide, hemoglobin A1c, renal function, liver function, blood lipid and C-reactive protein. The clinical features between two groups were compared and the relationship between serum C-peptide and NAFLD were also analyzed.<br />Results: Compared to the patients with LADA but without NAFLD, patients with both LADA and NAFLD had higher alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (γ-GT) (all P<0.01), but the serum total bilirubin (TBI) and direct bilirubin (DBI) level had no significant inter-group difference (P>0.05). The patients with both LADA and NAFLD had higher fasting C-peptide [0.62(0.33-0.93) vs 0.17 (0.05-0.50) nmol/L, P<0.001], 2 h postprandial C-peptide [1.57(0.78-1.88) vs 0.42(0.06-1.01) nmol/L, P<0.001] and more severe insulin resistance [0.8(1.0-2.5) vs 0.6(0.2-1.3), P<0.001]. Logistic regression analysis showed that there was a significant association between fasting C-peptide and the presence of NAFLD after controlling other confounding factors in patients with LADA.<br />Conclusions: The patients with both LADA and NAFLD had more severe metabolic disorders and insulin resistance. Serum fasting C peptide was independently associated with the presence of NAFLD in patients with LADA.
