Abstract:
Objective To investigate the relationship between plasma levels of chromogranin A (CHGA) and adi-pose triglyceride lipase (ATGL) in patients with type 2 diabetes (T2DM) combined non-alcoholic fatty liver disease (NAFLD). Methods The plasma levels of CHGA and ATGL were assayed by enzyme-linked immunosorbent assay (ELISA) in T2DM patients with NAFLD (group A, n=74), T2DM without NAFLD (group B, n=76), and normal group (group NC, n=75). The correlation between CHGA, ATGL and other metabolic index was analyzed. Results The plasma level of CHGA was significantly higher in group A (83.15±9.46) and group B (70.90±2.75) than that of group NC (46.74±8.15, P<0.01), and the level of CHGA was significantly higher in group A than that of group B (P<0.01). The plasma level of ATGL was sig-nificantly lower in group A (21.36±13.42) and group B (40.29±22.83) than that of group NC (72.30±26.41, P<0.01), and the level was lower in group A than that of group B (P<0.01). There was a negative correlation between the plasma CHGA, AT-GL and carbohydrate oxidation rate in group A. There was a positive correlation between fasting insulin (FINS), insulin resis-tance index (HOMA-IR), free fatty acid (FFA) and fat oxidation rate in group A. There was a negative correlation between plasma level ATGL and body mass index (BMI), FINS, cholesterol (TC), triglyceride (TG) and HOMA-IR, meanwhile, it was positively correlated with FFA. The multiple stepwise regression analysis showed that FINS, ATGL and FFA were indepen-dent variables for CHGA. The Logistic regression analysis showed that plasma levels of CHGA, ATGL and FFA were the in-dependent predictors of T2DM with NAFLD. Conclusion The plasma levels of CHGA and ATGL are closely correlated with substance and energy metabolism, and the interaction between them may play an important role in the pathogenesis of T2DM with NAFLD .
