Inhibition of C-Reactive Protein in Morbidly Obese Patients After Laparoscopic Sleeve Gastrectomy
Background Obesity is considered a low- grade chronic inflammatory condition as reflected by increased C-reactive protein ( CRP ) levels . Inflammation is emerging as a predictor of cardiovascular disease and it may be a precursor of the metabolic syndrome . Bariatric surgery is commonly performed as a treatment for morbid obesity offering significant reductions in premature myocardial infa rct ion . Laparoscopic sleeve gastrectomy ( LSG ) is a relatively new bariatric procedure that is currently used as a definitive procedure for weight loss . The aim of this study is to assess the impact of sleeve gastrectomy on CRP levels . Methods This study is part of an ongoing , prospect i ve , cohort study to evaluate LSG impact on iron indices . CRP levels were compared preoperatively and 6 months after surgery . Similarly , demographics including body mass index and excess weight were also compared at these same study points . Data were analyzed using Student paired t test and Pearson product moment correlation analysis . Results Twenty-nine morbidly obese patients were included . There was significant decrease in body mass index ( BMI ) between the preoperative and 6-month period ( 50.9 ± 13.2 and 35.1 ± 6.85 , respectively ; P < 0.001 ) . Also CRP levels were statistically significantly lower at 6 months after surgery ( preoperative 12.3 ± 7.53 mg/L and postoperative 5.6 ± 4.2 mg/L. P < 0.0001 ) . The significant weight loss as reflected by change in BMI was correlated with the difference between preoperative and postoperative CRP levels . Conclusions Massive weight loss in morbidly obese patients induced by LSG causes a significant decrease in CRP levels , which could reduce the risk of cardiovascular diseases in these patients
