Irisin is a myokine with potential anti-obesity properties that has been suggested to increase energy expenditure in obese patients. However, there is limited clinical information on the biology of irisin in humans, especially in morbidly obese patients undergoing bariatric surgery. We aimed to assess the association of circulating irisin concentrations with weight loss in obese patients undergoing bariatric surgery. This was a pilot, single-centre, longitudinal observational study. We recruited 25 morbidly obese subjects who underwent Roux-en-Y gastric bypass surgery (RYGBP), and blood samples from 12 patients were taken to measure serum irisin concentrations before, and one and nine months after surgery. Their clinical characteristics were measured for one year. The preoperative serum irisin concentration (mean 1.01 ± 0.23 μg/mL, range 0.73–1.49) changed bidirectionally one month after RYGBP. The mean concentration at nine months was 1.11 ± 0.15 μg/mL (range 0.92–1.35). Eight patients had elevated irisin levels compared with their preoperative values, but four did not. Elevations of irisin levels nine months, but not one month, after surgery, were associated with lower preoperative levels (p = 0.016) and worse weight reduction rates (p = 0.006 for the percentage excess weight loss and p = 0.032 for changes in body mass index). The preoperative serum irisin concentrations were significantly correlated with the percentage of excess weight loss for one year (R2 = 0.612; p = 0.04) in our study. Our results suggest that preoperative circulating irisin concentrations may be at least in part associated with a weight loss effect of bariatric surgery in morbidly obese patients. Further large-scale clinical studies are needed to ratify these findings.

INTRODUCTION The accuracy of prediction equations for estimating resting energy expenditure (REE) in morbidly obese patients is unclear. The aim of this study was to compare the REE measured using bedside indirect calorimetry with commonly used prediction equations. METHODS A total of 31 morbidly obese patients were studied. Pre-operative REE was measured with indirect calorimetry and compared with estimated REE using the Harris–Benedict and Schofield equations. All patients subsequently underwent a Roux-en-Y gastric bypass and measurements were repeated at six weeks and three months following surgery. RESULTS The mean age of the patients was 47 years. The mean pre-operative body mass index was 46kg/m2. The mean REE measured using indirect calorimetry was 1,980kcal/day. The estimated REE using the Harris–Benedict and Schofield formulae was 2,195 and 2,129kcal/day respectively. The equations overestimated REE by 10% and 7%. Body weight and body mass index reduced significantly following Roux-en-Y gastric bypass. There was no significant change in measured REE over the three-month period. After weight loss the difference between the estimated and measured REE reduced to 1–3%. CONCLUSIONS Prediction equations overestimate REE in morbidly obese patients. Their accuracy improved after surgery induced weight loss, confirming their validity for the normal weight population. Indirect calorimetry should be used in morbid obesity.

 Background: Surgically induced weight loss is a treatment option for the management of obesity and the related common disorders. This study evaluated the beneficial effects of bariatric surgery on metabolic profile and the prevalence of metabolic syndrome (MetS) among Iranian patients.Materials and Methods: A prospective observational study was performed on 26 morbidly obese patients scheduled for bariatric surgery, using laparoscopic Roux-en-Y gastric bypass (LRYGB). The parameters of hypertension, type 2 diabetes mellitus (T2DM), hyperlipidemia, MetS prevalence, and anthropometric measurements of Iranian patients, were recorded, at the preoperative visit and in follow-ups. The follow-up was performed for a median of 12 months, and the change in MetS prevalence and its componnts were assesed.Results: LRYGB induced a mean weight loss of 69.0±21.2%, after 12 months. Preoperative MetS was diagnosed in 21 patients (84%) and decreased to 6 patients (24%) after LRYGB (P=0.001). Likewise, the prevalence of hypertension was significantly decreased from 76% (pre-LRYGB values) to 20% (post-LRYGB values) (P=0.001). The prevalence of T2DM was also decreased from 20% to 8% (P=0.5).Conclusion: According to our results, RYGB produced a rapid and significant weight loss and improvement in hypertension and MetS within one year but there was a controversy about the improvement of T2DM, in Iranian morbidly obese patients.
