Abstract:
Objective:To investigate the relationship between sarcopenia and early renal dysfunction in elderly patients with type 2 diabetes mellitus(T2DM).Methods:A total of 198 elderly patients with T2DM aged over 60 years undergoing treatment in the Geriatric Department of Beijing Hospital from July 2018 to July 2019 were enrolled in this retrospective case-control study.The estimated glomerular filtration rate(eGFR)is calculated according to the CKD-EPI Cr-Cys formula.Based on the eGFR, the patients were divided into normal renal function group(n=63, in CKD 1 stage)and mild renal dysfunction group(n=135, in CKD 2-3a stage). All subjects underwent physical examination, laboratory examination and dual energy X-ray bone density examination. Results:The age, weight, body mass index, abdominal circumference, serum creatinine, cystatin C, uric acid, diastolic pressure, the proportions of diabetes and hypertension were lower, and the high-density lipoprotein cholesterol, appendicular skeletal muscle mass(ASM)and skeletal muscle mass index(SMI)were higher, in the normal renal function group than in the mild renal dysfunction group( P<0.05 or 0.01). Spearman correlation analysis showed that eGFR was positively correlated with SMI( r=0.343, P<0.01). Logistic regression analysis showed that body weight( OR=1.318, 95% CI: 1.091-1.594), uric acid( OR=1.007, 95% CI: 1.001-1.012), diastolic blood pressure( OR=1.072, 95% CI: 1.033-1.112), years of diabetes( OR=1.075, 95% CI: 1.013-1.142)were risk factors, and the LSM( OR=0.136, 95% CI: 0.047-0.392)and SMI( OR=0.778, 95% CI: 0.703-0.860)were protective factors for the early renal dysfunction in elderly patients with T2DM. Conclusions:Elderly patients with T2DM are often co-existed with sarcopenia.Sarcopenia is associated with early renal dysfunction in elderly patients with T2DM.
