Roux-en-Y gastric bypass decreases serum inflammatory markers and cardiovascular risk factors in obese diabetics.

BACKGROUND: Obesity and type 2 diabetes mellitus are associated with elevated levels of inflammatory markers. This chronic inflammation is known to contribute to increased risk of cardiovascular disease in these populations. Laparoscopic Roux-en-Y gastric bypass is associated with a high rate of diabetes remission. We hypothesize that laparoscopic Roux-en-Y gastric bypass decreases systemic inflammatory markers and cardiovascular disease risk factors in obese diabetics. METHODS: This was a single-institution prospective cohort study of 61 obese patients with type 2 diabetes mellitus. A total of 30 patients underwent laparoscopic Roux-en-Y gastric bypass surgery, and 31 patients underwent standard medical therapy with diabetes support and education. Collected data included preoperative and postoperative inflammatory biomarkers and clinical parameters. RESULTS: Twelve months after undergoing laparoscopic Roux-en-Y gastric bypass, controlling for sex and age, there was a significant correlation between a change in interleukin-6 and a change in systolic blood pressure (Spearman r = 0.41, P = .03). Similarly, when sex and age were controlled for in the laparoscopic Roux-en-Y gastric bypass group, a statistically significant relationship remained between percent excess weight loss and change in interleukin-6 (P = .001). CONCLUSION: A significant relationship exists between decreased systemic interleukin-6 levels and both excess weight loss and lowered systolic blood pressure after laparoscopic Roux-en-Y gastric bypass in obese patients with diabetes mellitus. These correlations may explain the decreased risk of cardiovascular disease after surgical weight reduction in this patient population.
