Abstract:
Objective To investigate the effect of body mass index (BMI)on short-term prognosis of patients after renal transplantation.Methods Clinical data of 1 041 adult patients undergoing the first renal transplantation in the Institute of Organ Transplantation of the 309 th Hospital of People's Liberation Army from March 2009 to March 201 3 were retrospectively studied.According to the Adult Obesity and Overweight Standard commonly used in China,these patients were divided into 4 groups:112 patients in BMI <1 8.5 kg/m2 group (emaciation group),606 patients in BMI 1 8.5-23.9 kg/m2 group (normal group),250 patients in BMI 24.0-27.9 kg/m2 group (overweight group)and 73 patients in BMI≥28.0 kg/m2 group (obesity group).The incidence of delayed graft function (DGF)and acute rejection (AR)of the 4 groups one year after renal transplantation were observed and compared.One-year patient and graft survival rates were calculated.The relationship between BMI and DGF was studied by univariate and multivariate Logistic regression analysis to investigate the effect of different BMI on DGF.Results After the follow-up for one year,the incidence of DGF in the obesity group was significantly higher than that in the emaciation group and the normal group(both in P <0.05).The difference in the incidence of acute rejection one year after renal transplantation as well as one-year patient or graft survival rate had no statistical significance (all in P >0.05).Univariate analysis showed that obesity increased the risk of DGF after renal transplantation (OR was 1 .33,P <0.05).Multivariate analysis showed that both overweight and obesity were independent risk factors of DGF after renal transplantation (OR was respectively 1 .56 and 1 .37,both in P <0.05).Conclusions Overweight and obesity increases the risk of DGF after renal transplantation,but do not increase the incidence of AR after renal transplantation and do no influence short-term patient and graft survival rates after renal transplantation.
