BackgroundDynapenic obesity and sarcopenic obesity increase cardiovascular disease (CVD) and mortality in nonuremic patients. The present study was designed to determine the prevalence of dynapenic obesity and sarcopenic obesity and their associations with CVD risk factors in peritoneal dialysis (PD) patients.MethodsAll eligible PD patients in Tehran peritoneal dialysis centers were included in this cross-sectional study. Skeletal muscle mass and fat mass were assessed using bioelectrical impedance analysis. Muscle strength and physical performance were determined using hand grip strength and a 4-meter walk gait speed test, respectively. In addition, a 5-mL blood sample was obtained from each patient.ResultsThe prevalence of dynapenic obesity and sarcopenic obesity were 11.4% and 3.8% in PD patients, respectively. Serum high-sensitive C-reactive protein (hs-CRP), soluble intercellular adhesion molecule type 1, triglyceride, total cholesterol, and low-density lipoprotein cholesterol were significantly higher in PD patients with dynapenic obesity than in dynapenic nonobese and nondynapenic nonobese patients. Similarly, serum concentrations of CVD risk factors in PD patients with sarcopenic obesity were higher than in nonsarcopenic nonobese patients, but these differences were statistically significant only for serum hs-CRP and triglyceride. In addition, muscle strength and skeletal muscle mass percentage were negatively associated with markers of inflammation and dyslipidemia, whereas body fat percentage was positively associated with these CVD risk factors.ConclusionThis study indicates that although the prevalence of dynapenic obesity and sarcopenic obesity are relatively low in PD patients, these disorders may be associated with CVD risk factors.
The results of the present study indicate that the DMS and MIS are almost similar to SGA for identifying PEW in HD patients, but it seems that the DMS is a more appropriate alternative tool for SGA in hospital routine assessments.
Background: This study was designed to investigate the associations between malnutritioninflammation score (MIS), dialysis-malnutrition score (DMS) and serum albumin with novel risk factors for cardiovascular diseases (CVD) in hemodialysis (HD) patients. Methods: In this crosssectional study, 291 HD patients were randomly selected from among 2302 adult HD patients in Tehran HD centers. The MIS and DMS were determined during one of the dialysis sessions in these patients. In addition, 4 mL blood was obtained before dialysis and analyzed for serum albumin and novel risk factors for CVD, including C-reactive protein (CRP), soluble intercellular adhesion molecule type 1 (sICAM-1), soluble vascular cell adhesion molecule type 1 (sVCAM-1), sE-selectin, malondialdehyde (MDA), nitric oxide (NO), endothelin-1 and lipoprotein (a) [Lp (a)]. Results: MIS and DMS were significantly positively correlated with serum CRP (p50.01) and sICAM-1 (p50.01), whereas serum albumin concentration was significantly negatively correlated with serum CRP (p50.01) and sICAM-1 (p50.01). There were no significant correlations between MIS, DMS and serum albumin with serum concentrations of sVCAM-1, sE-selectin, MDA, NO, endothelin-1 and Lp (a). Conclusion: This study indicates that proteinenergy wasting indicators in HD patients are associated with serum CRP and sICAM-1, as two CVD risk factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
