Evaluation of sequential monitoring of cytokines in renal allograft recipients / 中国免疫学杂志

ABSTRACT

Objective:To study the levels of TNF ? in serum and in urine and IL 6 in serum of renal allograft recipients with acute rejection, infection and CsA induced nephrotoxicity.Methods:The sequential monitoring of TNF ? and IL 6 was conducted by ELISA technique in 106 patients before and after renal transplantation.Results:The levels of IL 6 and TNF ? increased in the first day posttransplant, decreased and stabilized after 1 to 2 weeks, and increased 1 to 3 days prior to the clinical diagnosis in acute rejection, then decreased with effective treatment. IL 6 and TNF ? increased in serum in infection and had no difference in urine. TNF ? in serum and in urine and IL 6 in serum had no significant difference in CsA induced nephrotoxicity.Conclusion:It suggests that the sequential monitoring of IL 6 and TNF ? of renal allograft recipients can be used to estimate the function of graft, as markers of the early diagnosis of acute rejection.
