代谢综合征对老年人良性前列腺增生病程的影响

目的 探讨代谢综合征(MS)在老年人良性前列腺增生(BPH)病程中的作用.方法 101例BPH患者分为单纯BPH组45例与合并MS的BPH组56例,分析体质量指数(BMI)、腰围、高密度脂蛋白胆固醇(HDL-C)、空腹血糖(FBS)、胰岛素抵抗指数(HOMA-IR)等代谢性因素对BPH患者前列腺体积(PV)、血清前列腺特异性抗原(PSA)、国际前列腺症状评分(IPSS)、下尿路症状(LUTS)出现时间的影响.结果 合并MS的BPH患者PV明显大于单纯BPH患者(t=3.22,P=0.003),LUTS出现时间长于后者(t=2.02,P=0.046).超重和肥胖的BPH患者PV明显大于正常体质量组[分别为(49.44±26.83)ml与(38.10±10.64)ml,P=0.021;(51.7±22.2)ml与(38.10±10.64)ml,P=0.043]；腹型肥胖的BPH组患者PV明显大于非腹型肥胖的BPH患者组[(50.26±26.51)ml与(38.99±11.25)ml,P=0.005].低HDL-C水平组PV明显大于正常HDL-C水平组[(54.23±28.92)ml与(40.40±14.87) ml,P=0.009].FBS水平异常的BPH患者PV、PSA水平超过正常FBS水平者(t=3.17,2.41; P=0.035,0.013).合并胰岛素抵抗的BPH患者的PV明显大于胰岛素敏感者(t=3.43,P=0.001),LUTS出现时间在胰岛素抵抗组明显延长(t=3.58,P=0.001).PV与BMI (r=0.46,P=0.000)、FINS (r=0.42,P=0.001)、HOMA-IR (r=0.49,P=0.003)呈正相关；而与HDL-C(r=-0.38,P=0.000)呈负相关.多元逐步回归分析显示PV与HOMA-IR关系最密切.结论 MS对BPH的病程和发展具有明显的影响.

The effect of metabolic syndrome on pathogenesis of benign prostate hyperplasia

Objective To explore the effect of metabolic syndrome (MS) on the occurrence and development of benign prostate hyperplasia (BPH).Methods 101 elderly BPH patients were divided into two groups:BPH (n = 45) and BPH with MS (n= 56)group.The effects of metabolic indexes,including body mass index (BMI),waist,high density lipoprotein cholesterol (HDL-C),fasting blood glucose (FBS) and insuline resistance index (H()MA-IR),on prostate volume(PV),prostate-specific antigen (PSA),international prostate symptom score (IPSS) and lower urinary tract symptoms (LUTS) were surveyed in BPH patients.Results BPH with MS group showed significantly higher values of PV (t = 3.22,P= 0.003)and longer course of LUTS (t= 2.02,P =0.046) than BPH group.The BPH patients with overweight and obesity had significantly higher levels of PV(49.44±26.83 ml and 51.7±22.2 ml,P=0.021 and 0.043) than BPH patients with normal weight (38.10 ± 10.64 ml).Additionally,BPH patients with abdominal obesity had significantly higher levels of PV than BPH patients without abdominal obesity(50.26±26.51 ml vs.38.99± 11.25ml,P=0.005).BPH patients with low HDL-C had significantly higher PV than BPH patients with normal HDL-C[(54.23±28.92)ml vs.(40.40± 14.87) ml,P=0.009].The values of PV,PSA in the BPH patients with elevated FBS were significantly higher than in BPH patients with normal FBS (t=3.17 and 2.4I,P= 0.035 and 0.013).BPH patients with insuline resistance (IR) had higher values of PV and longer courses of LUTS than BPH patients without IR (t= 3.43 and 3.58,P-0.001).The PV was positively correlated with BMI (r= 0.459.P= O.OOO),FINS (r= 0.42,P=O.OOI),HOMA-IR (r= 0.49,P= 0.003) and gatively correlated with HDL-C (r= 0.38,P-0.000)- Multiple linear stepwise regression analysis showed that PV was closely correlated with HOMA-IR.Conclusions MS has evident effects on the occurrence and development of BPH.
