Living with a functioning kidney transplant at 74 yr or older: a national epidemiological study

The number of older patients living with a functioning kidney graft is increasing. However the safety of the immunosuppressive treatment and quality of life in this population have not yet been determined. All patients grafted in France since 1969, born before the January 1 1926 and living with a functioning graft on January 1 2000 were included in this national study including all 34 French transplant centers. Renal function, immunosuppressive treatment, comorbid conditions and quality of life were assessed. From the initial population of 446 patients, 113 (26.2%) were still alive in 2000 (study population). Mean age was 76 yr (range: 74-80) with a mean post-transplant follow-up of 9.9 yr (0.1-28.7). Average serum creatinine level was 129 micromol/L (55-286). Immunosuppression was heterogeneous and included triple therapy (18.6%), dual therapy (41.6%) and monotherapy (40.8%). A history of cancer was noted in 36 of the 113 patients (32.1%) whereas hypertension was the most frequent co-morbid condition (80.3%). Estimated quality of life using the Karnofsky scale was between 80 and 100 in 78.4% of the patients. The immunosuppressive regimen in older renal transplant recipients living with a functioning graft varied widely among the 34 French transplant centers. Renal function in this group of patients was good and quality of life seemed excellent. Cardiovascular disease and malignancies were the main co-morbid conditions.
