BACKGROUND High soluble suppression of tumorigenicity-2 (sST2) is a marker of poor prognosis in chronic inflammatory conditions. ST2 and its ligand interleukin (IL)-33 are elevated in adipose tissue of obese individuals. We aimed to evaluate circulating sST2 and IL-33 as possible markers of metabolic benefit in morbidly overweight patients after Roux-en-Y gastric bypass (RYGB) bariatric surgery. METHODS sST2, IL-33, high sensitive IL-6, high sensitive C-reactive protein (hsCRP), leptin, cholesterol metabolism and liver parameters were measured in 80 morbidly obese individuals before and 1 year after bariatric surgery. RESULTS sST2 was higher (P = 0.03) in diabetics as compared to individuals without diabetes. Baseline sST2 was also higher in males than in females (P= 0.0002). One year after bariatric surgery, sST2 levels were decreased (median 120, IQR 59-176 pg/mL) as compared to sST2 before surgery (median 141, IQR 111-181, P = 0.0024), and the diabetic group showed most pronounced reduction in sST2 (P = 0.0016). An association was found between sST2 and liver function parameters before and after bariatric surgery, and between baseline sST2 and total cholesterol, triglyceride, total low density lipoprotein (LDL), small dense LDL, Apolipoprotein B as well as with small dense high density lipoproteins (HDL). In the subgroup of diabetic patients positive correlation between IL-33 and sST2 (r = 0.44, P = 0.05) was noticed. CONCLUSIONS Circulating sST2 is associated with markers of liver functions and lipid metabolism in severely obese patients and a reduction of sST2 was shown after successful bariatric surgery, most prominently in diabetic patients.

特别是在进行减肥手术的糖尿病病态肥胖患者中,促炎性标志物可溶性抑制致瘤性2(ST2)降低。

背景技术致癌性-2(sST2)的高可溶性抑制是慢性炎症条件下预后不良的标志。肥胖个体的脂肪组织中ST2及其配体白介素(IL)-33升高。我们的目标是评估Roux-en-Y胃旁路(RYGB)减肥手术后病态超重患者循环sST2和IL-33作为可能的代谢益处标记。方法在减肥手术前和手术后1年,对80例病态肥胖患者进行了sST2,IL-33,高敏感性IL-6,高敏感性C反应蛋白(hsCRP),瘦素,胆固醇代谢和肝参数的测定。结果与没有糖尿病的人相比,糖尿病人的sST2更高(P = 0.03)。男性的基线sST2也高于女性(P = 0.0002)。减肥手术一年后,与手术前的sST2(中位数141,IQR 111-181,P = 0.0024)相比,sST2的水平降低(中位数120,IQR 59-176 pg / mL),糖尿病组的sST2降低最明显(P = 0.0016 )。在减肥手术之前和之后,sST2与肝功能参数之间以及基线sST2与总胆固醇,甘油三酸酯,总低密度脂蛋白(LDL),小密度低密度脂蛋白,载脂蛋白B以及小密度高密度脂蛋白之间存在关联( HDL)。在糖尿病患者亚组中,注意到IL-33与sST2之间呈正相关(r = 0.44,P = 0.05)。结论在严重肥胖的患者中,循环中的sST2与肝功能和脂质代谢的标志物有关,减肥手术成功后显示sST2减少,在糖尿病患者中最为明显。与手术前的sST2相比,IQR为59-176 pg / mL(中位数141,IQR 111-181,P = 0.0024),而糖尿病组的sST2减少最为明显(P = 0.0016)。在减肥手术之前和之后,sST2与肝功能参数之间以及基线sST2与总胆固醇,甘油三酸酯,总低密度脂蛋白(LDL),小密度低密度脂蛋白,载脂蛋白B以及小密度高密度脂蛋白之间存在关联( HDL)。在糖尿病患者亚组中,注意到IL-33与sST2之间呈正相关(r = 0.44,P = 0.05)。结论在严重肥胖的患者中,循环中的sST2与肝功能和脂质代谢的标志物有关,减肥手术成功后显示sST2减少,在糖尿病患者中最为明显。与手术前的sST2相比,IQR为59-176 pg / mL(中位数141,IQR 111-181,P = 0.0024),而糖尿病组的sST2减少最为明显(P = 0.0016)。在减肥手术之前和之后,sST2与肝功能参数之间以及基线sST2与总胆固醇,甘油三酸酯,总低密度脂蛋白(LDL),小密度低密度脂蛋白,载脂蛋白B以及小密度高密度脂蛋白之间存在关联( HDL)。在糖尿病患者亚组中,注意到IL-33与sST2之间呈正相关(r = 0.44,P = 0.05)。结论在严重肥胖的患者中,循环中的sST2与肝功能和脂质代谢的标志物有关,减肥手术成功后显示sST2减少,在糖尿病患者中最为明显。
