Long-term effects of kidney transplantation in children / 中华器官移植杂志

ABSTRACT

Objective To explore the long-term clinical effect of kidney transplantation in children.Methods The clinical data of 53 children with kidney transplantation from March 2008 to September 2014 were retrospectively analyzed.The influence of the dependent factors on the estimated glomerular filtration rate (eGFR) (greater than 90 mL/min/1.73 m2 or ＜90 mL/min/1.73 m2) was estimated in the three years after the operation,and the influencing factors were analyzed by the dual logistic regression equation.Results There were 19 cases of living donors,17 cases of organ donors after death,and 6 others.The 53 patients were followed up for 3-9 years.The level of blood creatinine was decreased from the preoperative (820.1 ± 323.1) μmol/L to (51.6 ± 24.9) μmol/L 3 years after the operation (P＜0.05).eGFR was increased to (103.5 ± 11.4) mL/min/1.73 m2at 3rd year after the operation from the preoperative (17.1 ± 7.8) mL/min/1.73 m2 (P＜0.05).The age of recipients,preoperative dialysis time,number of HLA mismatching and postoperative delayed graft function healing (DGF),rejection and infection were the influencing factors of eGFR at 3rd year postoperation (P＜0.05).The multi-factor binary logistic regression equation analysis showed that only rejection was the risk factor for eGFR at 3rd year p0ostoperation.Eight cases of DGF (8/53,15.1％) recovered rapidly.There were 6 cases of acute rejection (6/47,12.8 ％) and 1 case of chronic rejection (1/47,2.1％).There were 9 cases of infection (9/47,19.1％).There were 6 cases of recurrence after surgery.The 3-year recipient and kidney survival rate was 94.3％ (50/53) and 88.7％ (47/53) respectively.The average height of the patients in the first,second and third year after the surgery was increased by (4.6 ± 1.9) cm (0.5-19.1 cm),(3.7 ± 1.8) cm (0.7-14.3 cm) and (2.8± 1.2) cm (0.3-8.7 cm) respectively.Conclusion The long-term effect of children kidney transplantation is satisfactory.
