Plasma insulin, serum lipids and lipoproteins in gall stone disease in non-insulin dependent diabetic subjects: a case control study.

Abstract Background: Despite the fact that the majority of gallstones formed in the gallbladder are mainly composed of cholesterol, as they are formed from cholesterol-supersaturated bile, and hypercholesterolemia is a common metabolic disorder, which is closely related to cardiac, hepatic, renal and other oxidative damage inflammation and necrosis , there is still no consensus regarding the contribution of blood serum lipids in the pathogenesis of gallbladder stone disease (GSD). Here, we aimed to investigate the relationship between hypercholesterolemia and the risk of new-onset asymptomatic GSD, and to determine the prevalence of factors associated with new-onset asymptomatic GSD in patients with hypercholesterolemia. Methods: In this case-control study, we enrolled 927 Chinese patients with new-onset asymptomatic gallstone disease and 845 healthy controls starting in August 2012. Patients were matched for age, gender, race, occupation, systolic blood pressure, diastolic blood pressure, and fasting blood glucose levels (FBG). Body mass index (BMI), nonalcoholic fatty liver disease (NAFLD) and serum lipids indexes were compared and the relationships between BMI, blood lipid and gallbladder stone hazards were examined by using logistic multivariate regression models. Results: The result showed a significant higher morbidity with GSD in hypercholesterolemia than non-hypercholesterolemia patients (Χ 2 =17.211, P <0.001). Of hypercholesterolemia patients, low density lipoprotein (OR=1.493, P=0.029) and NAFLD (OR=2.723, P =0.022) were significant risk factors for GSD, while male sex (OR=0.244, P=0.033), weight (OR=0.961, P =0.022), high density lipoprotein (OR=0.305, P<0.001), and FBG (OR=0.687, P =0.034) significantly negatively correlated with GSD in univariate analysis. Multivariate logistic regression indicated weakly positive correlations with NAFLD (OR=3.284, P =0.054), and significant negative correlations with weight (OR=0.930, P =0.018), HDL-c (OR=0.144, P <0.001), and GSD. Conclusion: Hypercholesterolemia acts as an independent risk factor for new-onset asymptomatic GSD, while obesity and NAFLD are synergistic factors. Interestingly, we are the first to report that elevated weight was inversely associated with GSD in patients with hypercholesterolemia. The results of this study suggest that it is crucial to control hyperlipidemia effectively first instead of weight loss which might make the situation worse，and this might be of great significance for prevention of GSD in obese patients with hyperlipidemia.
