ABSTRACT
BACKGROUND: Sarcopenia is a common complication in end-stage renal disease. Low muscle strength and muscle mass are risk factors for cardiovascular disease and mortality in patients undergoing dialysis. We studied the relation between sarcopenia and pre-atherosclerotic markers and its effect on cardiovascular events and death in dialysis patients. METHODS: We measured muscle strength, muscle mass, carotid intima-media thickness, and pulse wave velocity in 106 patients. Sarcopenia was diagnosed according to the EWGSOP-2 suggestions. Patients with low muscle strength and low muscle mass were considered sarcopenic. The follow-up period for cardiovascular events and mortality was 24 months. RESULTS: The mean age and dialysis duration were 57.4 ± 16.6 and 6.5 ± 4.9 years, respectively. Of all patients, 53 (50%) were male and 70 (66%) were on hemodialysis treatment. Sarcopenia and low muscle strength were seen in 47.1% and 88.7%, respectively. Hemodialysis patients were more likely to be sarcopenic than peritoneal dialysis patients (p = 0.001). Ferritin and Kt/V levels were higher, and body mass index was lower significantly in sarcopenic patients (p < 0.001). There was no significant difference in carotid intima-media thickness and pulse wave velocity measurements between the groups (p = 0.62 and p = 0.68, respectively). There was no statistically significant difference in cardiovascular events and mortality in cases with and without sarcopenia (p = 0.43 and p = 0.17, respectively). CONCLUSION: There was no association between sarcopenia and pre-atherosclerotic markers, cardiovascular events, and all-cause mortality in dialysis patients. Techniques to detect low muscle strength and muscle mass need standardization, and new specific cut-off levels must be defined for dialysis patients.

Background: Endocan is a particular protein of endothelial cells. The purpose of this study was to determine the relationship of serum endocan levels with carotid intima-media thickness (cIMT), inflammation, and microalbuminuria in patients with newly-diagnosed hypertension.Materials-Methods: This prospective study included 61 patients with newly-diagnosed hypertension (HT) and 30 controls. Endocan, microalbuminuria and cIMT measurements were taken from all patients.Results: The serum endocan levels, the mean cIMT and microalbuminuria levels of patients with HT were significantly higher than those of the control group (p < .0001, p = .015 and p < .001, respectively).Conclusion: We found that endocan levels were increased in our study. This increase in endocan levels shows a relation with cIMT and microalbuminuria, which are associated with endothelial dysfunction.
