Low level of adiponectin predicts the development of Nonalcoholic fatty liver disease: is it irrespective to visceral adiposity index, visceral adipose tissue thickness and other obesity indices?

We aimed to study the correlation of adiponectin level with insulin resistance (IR), carotid intima-media thickness (cIMT), and various obesity indices especially visceral adipose tissue (VAT) thickness, and visceral adiposity index (VAI), in patients with NAFLD (n = 41), T2D (n = 22), NAFLD + T2D (n = 41), and healthy subjects (n = 20). Results showed the median level of adiponectin in patients with NAFLD (2.97 μg/mL) and ones with NAFLD + T2D (3.21 μg/mL) is significantly lower rather than in controls (4.39 μg/mL). Moreover, VAI is the only predictor for adiponectin concentration in the combination of patient groups and also in all participants independent of IR and other obesity indices. Adiponectin level had also a positive correlation with cIMT and IR in NAFLD patients. Interestingly, lower level of adiponectin was associated with the presence of T2D, NAFLD, and NAFLD + T2D independent of IR and obesity indices. Collectively, it seems that VAI reflecting visceral adipose tissue function is a possible predictor of adiponectin level.
