Aim: To identify specific causes of graft failure in a large sample of kidney transplant patients from a middle-income, developing country. Methods: Retrospective cohort study analyzing all consecutive single kidney transplants (KTs) performed at a single center in Brazil between January 1st 1998 and December 31st 2013. The database closing date was December 31st 2014. Results: Out of 10,400 KTs, there were 1191 (11.45%) deaths with a functioning graft, 40 cases (0.38%) of primary non-function (PNF) and 1417 cases (13.62%) of graft loss excluding death and PNF as the cause. Infectious complications (404 cases, 34% of all deaths) were the major cause of death. Most deaths due to infection occurred within the first year after transplantation (157 deaths, 38.86%). Immunologic mechanisms, comprising acute rejection and immune-mediated interstitial fibrosis/tubular atrophy (IF/TA), were responsible for 52% of all cases of graft failure not involving recipient death. Half of the losses by acute rejection occurred late after transplantation. Conclusion: Contrary to what is observed in developed countries, infectious complications are the main challenge with kidney transplantation in Brazil. Non-adherence to treatment also appears to contribute significantly to long-term kidney graft loss. Strategies for improvement should focus on better compliance and a greater safety profile of immunosuppressive treatment.
