RESUMO
Objective To investigate the influence of the high-flux hemodialysis (HFD) on inflammatory factors [C-reactive protein (CRP),interleukin-6 (IL-6),tumor necrosis factor-α (TNF-α)] and serum brain natriuretic (BNP) in patients before and after hemodialysis.Methods Fifty patients with MHD were enrolled in our hospital in 2013 and divided randomly into HD group (n =25),and HFD group (n =25).Serum CRP,IL-6,TNF-α,and BNP were measured in patients before and after the first hemodialysis session and after the treatment for 6 months later.Results Serum CRP,IL-6,and TNF-α in HD group after the first dialysis session and after the treatment for 6 months were statistically insignificant (P ＞0.05).In HD group,serum BNP was decreased after the first hemodialysis session and the treatment for 6 months later,the decreases was statistically significant (P ＜0.01 or P ＜0.05).In HFD group,serum CRP,IL-6,and TNF-α were decreased after the first treatment,the decreases were statistically insignificant (P ＞ 0.05).However,after the 6 mouths,the decreases were statistically significant (P ＜ 0.05).Serum BNP was decreased after the first hemodialysis session and the treatment for 6 months later,the decrease was statistically significant(P ＜ 0.01).Between two groups,the different time-point and the interaction of two groups and the different time-point,the discrepancy above them were statistically significant (P ＜0.01).Conclusions The high-flux hemodialysis can eliminate more inflammatory factors such as CRP,IL-6,TNF-α,and serum BNP in patients with uremia.Serum BNP Helps to adjust the dry weight in time,relieve cardiac load and reduce the incidence of heart failure.High-flux hemodialysis is one of the ways of treatment that reduce the morbidity of the heart failure.It can improve prognosis of the patients with MHD.
