Ways to optimize the assessment of lean body mass in hemodialysis patients
The aim. To conduct a comparative analysis of the effectiveness of methods for assessing lean body mass in haemodialysis patients. Patients and methods. A total of 317 patients receiving treatment with programmatic bicarbonate haemodialysis in 9 haemodialysis centers in 5 regions of the European part of the Russian Federation were examined for 8.2 ± 5.1 years, among them 171 women and 146 men, the average age was 57.1 ± 11.3 years. Dual-energy X-ray absorptiometry and bioimpedancemetry were used to assess lean body mass. Results. The results of determining the total lean body mass obtained from the results of dual-energy X-ray absorptiometry and bioimpedancemetry were compared using the Bland-Altman method. The correlation coefficient between the indicators was r = 0.994, p < 0.0001, delta (M ± σ) was -0.48 ± 0.91 kg, CI 95% (-0.71)-(-0.26) kg. Conclusion. Dual-energy X-ray absorptiometry has no significant advantages compared with bioimpedancemetry when evaluating lean body mass in haemodialysis patients. (For citation: Lavrishcheva IV, Jakovenko AA.
