BACKGROUND
We determined effects of bariatric weight loss surgery on serum tartrate-resistant acid phosphatase 5a (TRACP 5a), inflammatory cytokines and glucose homeostasis in severely obese Chinese adults.
METHODS
Severely obese adults undergoing bariatric surgery were recruited. Anthropometry, insulin resistance (IR), inflammatory markers and serum TRACP 5a were measured at baseline and 3, 6 and 12months postoperatively.
RESULTS
Data of 93 patients, including 69 non-diabetic (non-DM group) and 24 diabetic (DM group), were analyzed. Anthropometry decreased significantly at 3months postoperatively in both groups; low-density lipoprotein cholesterol decreased obviously at 3, 6 and 12months in non-DM group, while improving significantly at 6 and 12months in DM group. Homeostasis model assessment for IR (HOMA-IR) improved significantly at 3, 6 and 12months in non-DM group and 12months in DM group. In DM group, C-reactive protein (CRP) decreased significantly at 3months postoperatively and inflammatory markers interleukin-6 (IL-6) and TRACP 5a improved at 6months postoperatively; in non-DM group, serum TRACP 5a decreased obviously at 12months postoperatively without significant changes in CRP and IL-6.
CONCLUSIONS
Weight reduction by bariatric surgery decreases anthropometry, IR, lipids and inflammatory markers in severely obese Chinese adults.
