OBJECTIVE: Adiponectin (APN) circulates as high-molecular weight (HMW), medium-molecular weight (MMW), and low-molecular weight (LMW) forms. Nonalcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease. Currently, the role of LMW, MMW, and HMW APN remains largely unclear in NAFLD.
METHODS: We examined the variation of these forms and analyzed the related clinical characteristics in NAFLD. A total of 63 male NAFLD patients (mean age: 43.00 ± 6.10 years) and 70 healthy male subjects (mean age: 42.53 ± 7.98 years) were included in the study. Total APN and other clinical characteristics were measured. The changes in HMW, MMW, and LMW APN were determined in NAFLD patients and NAFLD patients on a high-fat diet, and the association between the groups was further analyzed.
RESULTS: Decreased levels of total APN and three APN isoforms were found in NAFLD. Significantly decreased levels of HMW (P < .01) and MMW (P < .001) were observed in NAFLD of high-fat diet patients. In NAFLD patients, height (R = -.270, P = .032) and N-epsilon-(carboxymethyl) lysine (R = -.259, P = .040) significantly correlated with total APN. HMW APN was significantly associated with fasting plasma glucose (R = .350, P = .016), alanine aminotransferase (R = -.321, P = .029), and aspartate aminotransferase (R = -.295, P = .045). Additionally, MMW APN was significantly associated with total cholesterol (R = .357, P = .014) and high-density lipoprotein (R = .556, P < .0001). Low-density lipoprotein (R = -.283, P = .054) was also clearly associated with LMW APN in NAFLD patients.
CONCLUSION: These results suggest that HMW and MMW APN may be involved in the pathogenesis and progression of NAFLD.
