Abstract:
Objective:To explore the prevalence and risk factors of sarcopenia in patients with maintenance dialysis (MHD).Methods:It was a cross-sectional study. Patients who received MHD treatment in the Blood Purification Center of Hainan Provincial People's Hospital in October 2019 were included as study subjects. The patients were divided into sarcopenia group and non-sarcopenia group according to whether they had sarcopenia or not. Chest CT imaging and laboratory examination data were collected. Dual-energy X-ray absorptiometry was used to measure the skeletal muscle mass. Chi-square test or Mantel-Haenszel trend chi-square test was used to compare the clinical data of patients with and without sarcopenia. Multivariate logistic regression equation was used to analyze the risk factors of sarcopenia.Results:A total of 182 MHD patients were enrolled in the study, and the prevalence of sarcopenia was 33.5% (61/182). The proportions of age ≥60 years old, diabetic nephropathy, tunneled-cuffed catheter, body mass index <18 kg/m 2, serum albumin <40 g/L, low density lipoprotein cholesterol ≥3.37 mmol/L, left ventricular ejection fraction <50%, chest CT-suspected pulmonary tuberculosis (PTB) and PTB in sarcopenia group were higher than those in non-sarcopenia group (all P<0.05). Multivariate logistic regression analysis results showed that left ventricular ejection fraction <50% (≥50% as a reference, OR=3.250, 95% CI 1.035-10.206, P=0.044), low-density lipoprotein cholesterol ≥3.37 mmol/L (<3.37 mmol/L as a reference, OR=6.354 ,95% CI 1.675-24.108, P=0.007), chest CT-suspected PTB (normal as a reference, OR=7.433, 95% CI 1.531-36.083, P=0.013), and PTB (normal as a reference, OR=28.871, 95% CI 3.208-259.872, P=0.030) were independent influencing factors of sarcopenia in MHD patients. Conclusions:The prevalence of sarcopenia is higher in MHD patients. Blood low-density lipoprotein cholesterol ≥3.37 mmol/L, ejection fraction <50%, chest CT-PTB and suspected PTB are independent risk factors of sarcopenia in MHD patients. Correcting left ventricular systolic function, regulating blood lipids and preventing PTB as early as possible can reduce the prevalence of sarcopenia in MHD patients.
