Effects of heterozygous blood purification on clearance of beta 2-microglobulin and microinflammatory state in patients on maintenance hemodialysis / 重庆医学

ABSTRACT

Objective To explore the effects of heterozygous blood purification on clearance of β2-microglohulin (β2-MG) and alleviation of microinflammatory state in patients on maintenance hemodialysis.Methods A total of 128 patients on maintenance hemodialysis for more than 6 months in the First Affiliated Hospital of Chongqing Medical University and the First Branch of the First Affiliated Hospital of Chongqing Medical University were enrolled and divided into the routine hemodialysis group and heterozygous blood purification group,64,cases in each group.The serum levels of β2-MG,high-sensitive C reactive protein (hs-CRP) and interleukin-6 (IL-6) of patients in the two groups were measured before and 6 months after the initiation of hemodialysis.Results After 6 months of treatment,the serum levels of β2-MG,hs-CRP and IL-6 were decreased in heterozygous blood purification group,compared with those before treatment,the differences were statistically significant (P＜0.05).In routine hemodialysis group,the serum level of β2-MG was decreased,and serum levels of hs-CRP and IL-6 were increased,,compared with those before treatment,no statistically significant difference was found (P＞0.05).Moreover,after 6 months of treatment,the serum levels of β2-MG,hsCRP and IL-6 in heterozygous blood purification group were significantly lower than those in the routine hemodialysis group (P＜ 0.05).Conclusion Heterozygous blood purification couldefficiently remove middle molecule toxins from blood,and alleviate microinflammatory status in patients on maintenance hemodialysis.
