Assessment of effective factors on renal transplantation survival and estimation of rejection hazard for transplanted in Mashhad Qaem hospital

Background and Objctive: Renal transplantation is one of the most effective treatments for chronic liver patients. Some of the risk factors of transplant survival are included Blood pressure، age of patient and hepatitis. The aim of this study is to investigate factor influenced on patients underwent renal translation from 1368 to 1385 in Qaem hospital medical Center who received the transplant for the first time. This study was a historical cohort study that conducted to investigate the effect of risk factors on renal transplant survival and to estimate the rate of transplant rejection. Age and gender of kidney transplant recipient، type of kidney transplant donor، number of dialysis before translation in a month، hepatitis and blood group were included in the study. Statistical analysis was conducted using Kaplan-Meier estimator، Log-Rank test، Cox Regression model by SAS version 9. 2. From 1340 patient under study، 842 patients (63%) were male. number of dialysis in a month and age of recipient are variables that effect on renal survival significantly in Cox model. Hazard for transplant rejection will 4% decreases per unit increase in age and 60% increase per unite increase in number of dialysis. The results showed that age of recipient، having hepatitis C virus and the number of dialysis before transplantation have significant effect on the survival of renal transpiration after adjusting the effect of other variables that should be considered.
