Abstract
Background: Recent studies showed that fetuin-A and matrix metalloproteinase-7 (MMP-7) are type 2 diabetes mellitus (T2DM)-associated markers. Bariatric surgery not only reduces body weight but also improves T2DM. This study aimed to investigate the changes of fetuin-A and MMP-7 in obese subjects with and without T2DM after bariatric surgery. Methods: We enrolled 130 obese subjects that received bariatric surgery, including 41 Roux-en-Y gastric bypass (RYGB), 67 mini-gastric bypass (MGB), and 22 sleeve gastrectomy (SG) patients. Forty-three patients suffered from T2DM prior to surgery. The fasting serum fetuin-A and MMP-7 levels were measured before and 1?year after surgery. Results: Only five of 43 patients remained diabetic after surgery. Preoperative T2DM patients had higher fetuin-A and MMP-7 levels than non-T2DM subjects. RYGB, MGB, and SG all decreased the fetuin-A levels 1?year after the operation. The MMP-7 levels were not changed after RYGB, MGB, or SG. In multivariate analyses, the preoperative fetuin-A was significantly related to the diastolic blood pressure (DBP) and glycosylated hemoglobin (HbA1c), while the postoperative fetuin-A was independently related to the waist-to-hip ratio and HbA1c. Moreover, the preoperative MMP-7 level was significantly related to age, DBP, aspartate transaminase, alanine transaminase, and gamma-glutamyl transferase (rGT), while the postoperative MMP-7 level was independently related to age and rGT. Conclusions: The fetuin-A and MMP-7 levels are both higher in obese T2DM than non-T2DM subjects. The level of fetuin-A is reduced after RYGB, MGB, and SG, but the level of MMP-7 remains unchanged. ? 2015, Springer Science+Business Media New York.
