    Abstract:
    INTRODUCTION: This study was aimed to assess irisin levels in obesity (OB) and T2DM individuals and investigate the dynamic changes of irisin, bone mineral density (BMD), bone mineral content, and body composition in 19 OB patients after laparoscopic bariatric procedures, and also to evaluate the correlation of irisin, with BMD and body composition. METHODS: Forty-five OB, 20 T2DM, and 20 healthy adults had been recruited. Levels of irisin were measured in all subjects. Metabolic characteristics were obtained from OB and T2DM patients. Nineteen patients were randomly assigned to be received Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) procedure and to be completed 6-month follow-up. Irisin, BMD, bone mineral content, and body composition were measured at each visit. RESULTS: Significantly higher circulating irisin levels were measured in the OB group compared with T2DM and control groups. FINS, C-P, HOMA-IR, FBCI, HBCI, ALT, AST, and UA levels of OB were significantly higher than those of T2DM patients. While FBG and HbA1c of the OB were significantly lower than T2DM group. There were significant differences among circulating irisin, BMD, and body composition after laparoscopic bariatric surgery. Levels of irisin were decreased after operations including both LRYGB and LSG surgery compared with preoperation. At each time point (1, 3, and 6 months) of postoperation, there was no significant difference in percentage of total weight loss between LSG and LRYGB group. The positive correlation of irisin levels with total BMD, muscle, and fat masses were found during 6-month follow-up after surgery. CONCLUSIONS: The levels of irisin were higher in OB patients. There were positive correlations of irisin levels with total BMD, muscle, and fat masses during 6-month follow-up after surgery. Irisin may be involved in the occurrence and development of obese and it is related to BMD and body composition. Both LRYGB and LSG operations could decrease the circulating levels of irisin.
