Does immigration background influence outcomes after renal transplantation?
Migration implies differences in lifestyle, dietary and health behavior practice, and adherence, all of which are relevant factors in terms of disease outcome. However, renal transplantation in immigrant groups has been rarely studied in Europe. We have investigated the effect of immigration on outcomes in all children who underwent renal transplantation (RTx) at the Medical University of Vienna. From 1978 to 2007, 196 children underwent 236 RTx. In comparison to native recipients, immigrant recipients (31 boys, 17 girls) tended to be younger and male, with a higher rate of congenital renal diseases. The percentage of adolescent immigrant recipients tended to be lower, and living donation tended to be higher. In both the immigrant and native groups, RTx outcomes at 1, 5, and 10 years, including acute rejection rate (34 vs. 44, 55 vs. 62, 74 vs. 78%, respectively) and patient (98 vs. 92, 88 vs. 91, 80 vs. 82%, respectively) and graft survival (83 vs. 82, 79 vs. 65, 66 vs. 51%, respectively) were similar. All outcomes improved over time. In conclusion, this study demonstrates that outcomes in RTx are equivalent in immigrants and native recipients. Potential barriers to success among the Austrian immigrant recipient population may have been overcome by protective factors. These results should serve as a catalyst to retrieve data from larger databases to verify these single-center results.
