ABSTRACT
Objective To investigate the potential correlation between serum magnesium and malnutrition-inflammation-atherosclerosis (MIA) syndrome in maintenance hemodialysis (MHD) patients.Methods A total of 120 patients who received MHD in Department of Blood Purification of Beijing Chaoyang Hospital from March to August 2013 were enrolled.Anthropometric and laboratory data were collected for the analysis of correlation between serum magnesium and indicators relating to malnutrition,chronic inflammation,and atherosclerosis,and the analysis of relevant factors of MIA syndrome.Results In the 120 MHD patients,the mean serum magnesium level was (1.11 ±0.14) mmol/L.44 patients had malnutrition (36.7%),whose serum magnesium level was significantly lower than that of patients in normal nutritious status [(1.04 ±0.12) mmol/L vs.(1.14 ±0.15) mmol/L,t =3.576,P =0.001] ; 43 patients had chronic inflammation (35.8%),with serum magnesium level significantly lower than that of patients without inflammation [(1.07 ±0.13) mmol/L vs.(1.13 ±0.15) mmol/L,t =2.138,P =0.035]; 79 patients had atherosclerosis (65.8%),whose serum magnesium level was significantly lower than that of patients without atherosclerosis [(1.08 ±0.12) mmol/L vs.(1.15 ±0.08) mmol/L,t =0.385,P =0.019] ; and 26 patients had MIA syndrome (21.7%),whose serum magnesium level was significantly lower than that of non-MIA patients [(1.02 ± 0.10) mmol/L vs.(1.13 ± 0.14) mmol/L,t =3.534,P =0.001].Serum magnesium level was found negatively correlated with high-sensitivity C-reactive protein (hs-CRP,r =-0.237,P =0.010) and carotid intima-media thickness (IMT,r =-0.331,P =0.000),and positively correlated with serum albumin,blood urea nitrogen,serum creatinine,uric acid,serum potassium,triceps skin-fold thickness,mid-arm circumference,mid-arm muscle circumference and hemoglobin (r =0.191,P =0.037; r =0.345,P =0.000; r =0.242,P=0.008; r =0.282,P=0.002; r=0.254,P=0.005; r=0.265,P=0.011; r=0.233,P=0.018; r=0.282,P=0.007; r=0.374,P =0.000).Multivariate logistic regression analysis showed that age (OR =1.142,95% CI =1.026-1.271,P=0.049),hs-CRP (OR=1.415,95% CI=1.152-1.740,P=0.001),IMT (OR =1.386,95% CI=1.009-1.904,P=0.044),serum albumin (OR =0.944,95% CI=0.910-0.978,P=0.002) and serum magnesium (OR =0.886,95% CI =0.788-0.996,P =0.042) were related factors of MIA syndrome.Conclusions Serum magnesium level is correlated to malnutrition,inflammation,atherosclerosis,and MIA syndrome in MHD patients.
