RESUMO
Objective:To investigate the effects of serum sICAM-1 and sVCAM-1 in renal allograft recipients with infection, acute rejection and CsA-induced nephrotoxicity for the clinical significance of early diagnosis and differential diagnosis.Methods:The sequential monitoring of serum sICAM-1 and sVCAM-1 were conducted by ELISA technique in 86 patients before and after renal transplantation.Results:The levels of serum sICAM-1 and sVCAM-1 increased in the first three day posttransplantation, decreased and stabilized after one to two weeks,increased one to three days prior to the clinical diagnosis in acute rejection and decreased with effective treatment,increased in infection and had no significant difference in CsA-induced nephrotoxicity.Conclusion:Sequential monitoring of serum sICAM-1 and sVCAM-1 of renal allograft recipients can be used to estimate the function of graft,as markers of the early diagnosis and differential diagnosis of acute rejection.
RESUMO
Objective:To investigate the effect of anti-CD25 monoclonal antibody in preventing acute rejection after renal transplantation.Methods:71 patients were randomly divided into two groups;treatment gourp( n =26)and control group( n =45).The treatment group received anti-CD25 monoclonal antibody twice before and after renal transplantation.The occurrence of rejection postoperation and renal function and T lymphocyte subtypes were sequentially monitored.Results:The occurrence of aute rejection in treatment group in 1,3,6 and 12 months after renal transplantation was 7.7% ,19.2%,23.1% and 30.8%,while it was 15.6%,28.9%,35.6% and 46.7% in control group.There was significant difference between the two groups( P0.05 ).Conclusion:It suggests that anti-CD25 monoclonal antibody reduce the occurrence of acute rejection and have no influence on T lymphocyte subtypes.
RESUMO
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.
