Angiotensin II receptor blockade is associated with preserved muscle strength in chronic hemodialysis patients

BACKGROUND: Sarcopenia, defined as low muscle mass and strength, is highly prevalent in patients undergoing chronic hemodialysis (HD). However, muscle function and muscle mass do not share the same clinical relevance. In fact, muscle strength was more closely associated with the risk of mortality in chronic HD patients than was muscle mass. Therefore, to identify the risk factors of muscle weakness is vital. Angiotensin II overexpression had been recognized to impair skeletal muscle strength. Accordingly, angiotensin II receptor blockers (ARBs) potentially possess a muscle protective effect. This cross-sectional study aimed to identify the factors associated with low muscle strength and to explore the relationship between ARB use and muscle strength in chronic HD patients.

METHODS: A total of 120 chronic HD patients, aged 63.3 ± 13.2 years, were included in this study. Basic characteristics, handgrip strength (HGS), body composition, and nutritional status were assessed, and blood samples for biochemical tests were obtained. We divided these participants into normal- and low HGS groups according to the consensus of the European Working Group on Sarcopenia in Older People (EWGSOP).

RESULTS: We observed that 78 (65.0%) patients had low HGS. In our cohort, we found that height (r = 0.653; P <  0.001), weight (r = 0.496; P <  0.001), body mass index (r = 0.215; P = 0.020), skeletal muscle index (r = 0.562; P <  0.001), albumin (r = 0.197; P = 0.032), and serum creatinine (r = 0.544; P <  0.001) were positively and age (r = - 0.506; P <  0.001), subjective global assessment (SGA) score (r = - 0.392; P <  0.001), fractional clearance index for urea (Kt/V) (r = - 0.404; P <  0.001) and urea reduction ratio (URR) (r = - 0.459; P <  0.001) were negatively correlated with HGS. According to our analysis, age (Odds ratio, OR = 1.11, 95% confidence interval, 95% CI = 1.05-1.17, P <  0.001), HD duration (OR = 1.01, 95% CI = 1.00-1.02, P = 0.010), diabetes (OR = 13.33, 95% CI = 3.45-51.53, P <  0.001), Kt/V (OR = 1.61, 95% CI = 1.06-2.46, P = 0.027), and SGA score (OR = 1.19, 95% CI = 1.03-1.38, P = 0.017) were regarded as independent predictors of low HGS. In contrast, ARB use (OR = 0.25, 95% CI = 0.07-0.93, P = 0.039) was independently associated with preserved HGS in chronic HD patients, after adjustment for multiple confounding factors.

CONCLUSIONS: Our study is the first report in chronic HD patients to indicate a potentially protective effect of ARB on muscle strength. However, further longitudinal follow-up and intervention studies are needed to confirm this finding.
