RESUMO

Objective:To compare the consistency between bioelectrical impedance analysis(BIA)and dual-energy X-ray absorptiometry(DXA)in skeletal muscle mass assessment in elderly patients with advanced chronic kidney disease(CKD), and to provide a basis for accurate clinical diagnosis of sarcopenia.Methods:Elderly patients with advanced CKD at the Department of Nephrology of Shanghai Sixth People's Hospital were included.Parameters for physical performance included handgrip strength and gait speed, and body muscle mass was measured by DXA and multifrequency BIA.The consistency between the two methods was assessed by the intraclass correlation coefficient, Bland-Altman analysis and kappa coefficient test.Results:This study included 67 elderly patients with advanced CKD with a mean age of(70.7±6.1)years and an average BMI of(24.6±3.5)kg/m 2.The proportion of enrolled male patients was 61.2% and the mean estimated glomerular filtration rate was(27.7±12.7)ml·min -1·1.73m -2.The intraclass correlation coefficients of muscle mass and appendicular skeletal-muscle mass index(ASMI)measured by BIA and DXA ranged from 0.81 to 0.90.Bland-Altman analysis showed that BIA overestimated muscle mass against DXA, and the mean difference in ASMI was(0.44±0.13)kg/m 2.In addition, there was a moderate agreement between the two measurement methods for determining muscle loss(Kappa=0.47). Conclusions:BIA and DXA offer a fair level of consistency in the assessment of muscle mass in elderly patients with advanced CKD.However, compared with DXA, BIA overestimates muscle mass in elderly patients with CKD.

RESUMO

Objective:To investigate the clinical characteristics and related risk factors of sarcopenia in elderly patients undergoing maintenance hemodialysis.Methods:This was a retrospectively study involving 135 elderly hemodialysis patients aged(70.6±7.7)years, with 46(34.1%)females and a mean hemodialysis duration of(3.2±2.9)years, at Shanghai Sixth People's Hospital.The incidence of sarcopenia in patients was examined by measuring handgrip strength, walking speed and muscle mass of the limbs using bioelectrical impedance analysis.Related risk factors were analyzed with univariate and multivariate logistic regression analysis.Results:Among 135 elderly hemodialysis patients, the incidence of sarcopenia was 62.9%(85 cases), and severe sarcopenia cases accounted for 44.4%(60 cases). Compared with the non-sarcopenia group, patients with sarcopenia were older, had lower body mass index(BMI)and handgrip strength, walked more slowly and had less muscle mass in their limbs.Advanced age, low BMI and long dialysis duration were correlated with the high incidence of sarcopenia in elderly dialysis patients.The odds ratio( OR)for sarcopenia increased by 12% per year, and the OR decreased by 32% with an increase of 1.0 kg/m 2 in BMI.Advanced age and lower BMI were also correlated with a high incidence of severe sarcopenia( OR=1.12, 95% CI: 1.05~1.18; OR=0.84, 95% CI: 0.74~0.95; all P<0.01). Conclusions:The incidence of sarcopenia is high in elderly hemodialysis patients and is closely related to advanced age and low body weight.Improving nutritional status and avoiding low body weight will help reduce the occurrence and development of sarcopenia in elderly hemodialysis patients.

RESUMO

Objective To observe the occurrence and risk factors of arrhythmia in chronic kidney disease (CKD) patients in different stages of renal function. Methods A total of 405 CKD patients were enrolled in this study and none of them received renal replacement therapy.The 24 h dynamic electrocardiogram (DCG) was performed,and baseline characteristics were compared.Multivariable Logistic regression analysis was used to examine the relationship between the severe arrhythmia and the potential risk factors,such as age,gender,CKD stage,diabetes,hypertension,hyperpotassaemia,left ventricular hypertrophy (LVH),etc. Results There were 69 patients (17.04%),79 patients (19.51%),82 patients (20.25%),88 patients (21.73 %) and 87 patients (21.48%) in CKD stage 1,2,3,4 and 5,respectively.As high as 45.68% of all the patients had severe arrhythmia,represented by 27.54%,29.11%,42.68%,57.95% and 65.52% in CKD stages 1-5 respectively.The occurrence of severe arrhythmia increased as the eGFR decreased in CKD stages 2,3,4 (p<0.05).On multivariable Logistic regression analysis,the occurrence of severe arrhythmia was related to LVH,CKD stage,diaberes hyertension and hyperpotassaemia are signidicantly assoxiated with severe arrhythmia.

RESUMO

Objective To observe the therapeutic effects of the drugs alternation multiple stages and long term therapy in elderly patients with recurrent urinary tract infection.Methods The patients were divided into elderly group (age≥65 years,n=30) and non-elderly group (n=48).The multiple effective antibiotics were selected for alternate use.The treatment included four periods as follows:(1)Treatment period:the regular dose of antibiotic was maintained until the urine routine test result became normal;(2)Consolidation period:the dosage of antibiotic was reduced;(3)Maintenance period:the dosage of antibiotic was reduced to once every night and the treatment should be kept for three months;(4)Observation period:the patients were observed for six months after withdrawal of antibiotics.During the treatment,if the urine routine test became abnormal repeatedly,the patient should return to the previous treatment period.During the treatment and consolidation period,each medication should be applied for one week alternatively.Results Among 78 patients,69 cases (88.5%) were cured,7 cases (8.9%) were effective,and two cases (2.56%) were invalid.There were 28 cured cases,1 effective case and 1 invalid case in elderly group.The corresponding data were 41,6 and 1 in non-elderly group,respectively.There was no difference in cure rate between the two groups (F= 0.469).Compared with non-elderly group,the overall treatment time [(54.8± 16.2)weeks vs.(44.5± 13.7) weeks,t= 2.8467,P<0.01],treatment period [( 34.3± 15.2) weeks vs.(26.2±14.8) weeks,t=2.2081,P<0.05] and consolidation period [(5.7±2.6) weeks vs.(4.1±0.2) weeks,t=3.9369,P<0.01] were all prolonged in elderly group.But there was no difference in maintenance period [(14.8±4.6) weeks vs.(14.2±3.1) weeks,t=0.6480,P>0.05].There were no markedly changes in blood routine,liver and kidney function during the course of treatment.Conclusions For the elderly patients with recurrent urinary tract infection,the drugs alternation,multiple stages and long-term treatment has a high cure rate and no adverse effect on blood routine,liver and renal function.
