inflammation and Dimethyl Arginine Asymmetric (ADMA) are related to mortality in hemodialysis (HD). Study aims to analyze interaction between ADMA and CRP among DM- and + patients in HD.


Pre-HD ADMA measured by HPLC in 202 adults prevalent in HD. CRP measured by ultra-sensitive immunoturbidimetry. Association with mortality in 4 years through SPSS 23.0.


Forty individuals censored by transplantation. DM+ were older (57.1 ± 13.3 x 50.2 ± 15.1 years, P = .002), with higher BMI (25.9 ± 2.9 x 24.9 ± 2.4, P = , 017), and higher prevalence of coronary disease (36.9% x 15.0%, P = .001). ADMA and CRP were similar between DM+ and DM-. ADMA and CRP were similar between DM + and DM-. Only ADMA - median IQR μM - (0.88 0.60 - 1.37 and 1.71 1.34 - 2.17 P =, 000) and median CRP IQR mg / dL - (0.38-0.15 - 1.18 and 0.77 0.23 - 2.25 P = .034) differed between individuals with no evolution to death (O-) or with (O +). Only ADMA - median IQR μM - (1.03 0.81 - 1.55 and 1.95 1.75 - 2.54 P =, 000) differed between DM-, O- or O+. In binary logistic regression, ADMA remained as a variable related to mortality in DM- (OR 2,379 CI 1.36 - 3.68 P =, 000). DM + showed no differences between O- or O+.In 4 groups according to ADMA and CRP medians: I = lower ADMA and CRP, II = higher CRP and lower ADMA, III = lower CRP and higher ADMA and IV = higher ADMA and CRP - respective mortalities of 0.0%, 0 , 0%, 31.0%, 69.0% among DM- (P =, 000). No differences in mortality between DM + (GRAPHIC).


ADMA has a significant relationship with mortality in prevalent DM- in HD and can improve evaluation of mortality risk in these patients. Other risk factors may overlap ADMA in DM +. Synergistic effect of ADMA and CRP; Mortality in group IV in DM- in HD higher than simple addition of mortality in group III with II or I. Previous work reported no differences between DM + and DM-, but DM + totaled 15% of the cohort (CJASN 6 1714 -21.2011).
