慢性肾脏病5期患者体质成分与骨量减少的相关性
Correlation between body composition and bone loss in patients with stage 5 chronic kidney disease
目的 探讨慢性肾脏病(CKD)5期患者体质成分对骨量减少的影响。 方法 对217例透析前CKD 5期患者进行回顾性分析;采用联影AI影像辅助诊断系统对腹部CT图像进行分析,获取骨密度及体质成分,记录临床基本数据并收集相关生化指标。根据CKD患者的骨密度值分为骨量正常组和低骨量组,采用独立样本t检验比较两组间的临床资料、生化指标和体质成分差异,通过二元Logistic回归分析CKD 5期患者低骨量的影响因素,采用受试者工作特征(ROC)曲线分析评估相关指标对低骨量的预测价值。 结果 骨量正常组153例、低骨量组64例。与骨量正常组相比,低骨量组患者年龄更高,有吸烟史及罹患肌少症的比例更高,且血肌酐(Scr)、肌酐/胱抑素C(CCR)、甲状旁腺激素(PTH)及骨骼肌指数(SMI)水平较低,而糖基化血红蛋白(HbA1c)及内脏脂肪面积与皮下脂肪面积比值(V/S)较高,差异均具有统计学意义(P0.05)。二元Logistic回归分析得出年龄、V/S是CKD 5期患者低骨量的危险因素(P0.05,β0),CCR、SMI是低骨量的保护因素(P0.05,β0)。ROC曲线分析显示,SMI、CCR及V/S对骨量减少均有一定预测价值,其曲线下面积分别为0.593,0.678和0.639(P0.05)。 结论 V/S、CCR、SMI是慢性肾脏病患者低骨量的独立影响因素,对CKD患者骨量减少具有一定的预测价值。
Objective To investigate the impact of body composition on bone loss in patients with stage 5 chronic kidney disease(CKD). Methods A retrospective analysis was conducted on 217 pre-dialysis patients with stage 5 CKD. The uAI medical imaging-assisted diagnostic system was used to analyze abdominal CT images for obtaining bone mineral density and body composition data. Clinical baseline data were recorded and relevant biochemical indicators were collected. Patients were divided into a normal bone mass group and a low bone mass group based on bone mineral density values. Independent sample t-test was used to compare differences in clinical data, biochemical indicators, and body composition between the two groups. Binary logistic regression analysis was employed to identify influencing factors for low bone mass in stage 5 CKD patients, and receiver operating characteristic(ROC) curve analysis was used to evaluate the predictive value of related indicators for low bone mass. Results There were 153 patients in normal bone mass group and 64 patients in low bone mass group. Compared with normal bone mass group, the patients in low bone mass group were older, had a higher proportion of smoking history and sarcopenia, and exhibited lower levels of serum creatinine(Scr), creatinine/cystatin C ratio(CCR), parathyroid hormone(PTH), and skeletal muscle index(SMI), and higher levels of glycated hemoglobin(HbA1c) and the visceral-to-subcutaneous adipose tissue area ratio(V/S)(P0.05). Binary Logistic regression analysis identified age and V/S as risk factors for low bone mass in stage 5 CKD patients(P0.05, β0), while CCR and SMI were protective factors(P0.05, β0). ROC curve analysis showed that SMI, CCR, and V/S all had certain predictive value for bone loss, with area under the curve(AUC) values of 0.593, 0.678, and 0.639, respectively(P0.05). Conclusion V/S, CCR, and SMI are independent influencing factors for low bone mass in patients with CKD and possess certain predictive value for reduced bone mass.
