Effect of Massive Weight Loss on Inflammatory Adipocytokines and the Innate Immune System in Morbidly Obese Women

Context: Obesity may be regarded as a low-grade inflammatory state. Objective: The aim of this study was to evaluate changes in pro-inflammatory adipocytokines and the innate immune system, cardiovascular risk, and insulin sensitivity after massive weight loss. Design: This was a longitudinal study. Setting: The study was conducted at Catholic University, Rome. Subjects and Methods: There were 10 normoglucose-tolerant obese women evaluated before and 36 months after bilio-pancreatic diversion (BPD). Glucose sensitivity (M value) was estimated using the euglycemic-hyperinsulinemic clamp. Mannan-binding lectin (MBL), bactericidal/permeability increasing protein (BPI), α-defensins, soluble CD14 receptor (sCD14), C-reactive protein, adiponectin, leptin, visfatin, IL-6, and TNF-α were assayed. Results: After massive weight loss (53% of excess body weight), leptin (P ≤ 0.0001), IL-6 (P ≤ 0.0001), α-defensins (P ≤ 0.001), and C-reactive protein (P ≤ 0.0001) decreased significantly. Adiponectin increased signific...
