ABSTRACT
Objective To study the influence of tumor necrosis factor-alpha (TNF-?) gene polymorphism on infections in old kidney allograft recipients. Methods The TNF-? genotype in -308 promoter position was determined in 87 old kidney transplant recipients from January 1998 to January 2001 by PCR using sequence -specific primer(PCR-SSP), and then the effects of genotypes on the frequency of rejection and infection, and the survival rate of the patient and graft were observed. Results 58 recipients were low TNF-? production genotype and 29 were high TNF-? production genotype. There were no significant differences in the frequency of rejection, median day of first infection and kinds of infections between the two genotypes. The frequency and times of infections were higher in low TNF-? genotype recipients than those in high TNF-? genotype recipients(67 2% vs 41 4%, P=0 021; 1 68 vs 0 86, P=0 017). The survival rates of the patients and grafts were equal in both the two groups. Conclusion The old recipients with low TNF-? production genotype may be susceptible to infections under routine immunosuppression. It is helpful for old recipients to perform more individual immunosuppression regimens according to TNF-? genotype.
