Abstract
In this study, we analyzed the incidence of complications and clinical results of 57 patients who received kidney transplants at our institution and survived with a functioning allograft for 10 years or longer. All patients received their care at out center and their clinical and laboratory data were monitored routinely at minimum monthly intervals. In this second decade, during a mean follow-up of 2.8 .+-. 2.2 years (range 0.4-7.8 years), 7 patients suffered graft loss (chronic rejection 6; irreversible acute tubular necrosis from aminoglycosides 1) and 7 others died with a functioning allograft (causes: hepatic failure 2, sepsis 2, malignancy 2, and cardiac infarction 1). The cumulative patient survival was 96% at 11 years and 85% at 15 years. The corresponding graft survival rate was 92% at 11 years and 71% at 15 years. Of the 43 patients currently followed, 38 are fully rehabilitated, 4 are partially rehabilitated, and 1 is medically disabled. The complications observed were: infection in 25 patients (44%), hypertension in 24 (42%), hyperlipidemia in 23 (40%), liver disease, 22 (39%) musculoskeletal problems in 21 (37%), cataracts in 19 (33%), rejection in 15 (26%), malignancy in 9 (16%), vascular occlusive disease in 9 (16%), gastrointestinal disorders in 9 (16%), and other problems not included in the above categories in 26 (46%). Our observations suggest that renal transplant recipients experience significant morbidity and mortality even in the second decade. Continued medical follow-up is therefore essential for an early diagnosis and management of these late complications. Measures directed at prevention and therapy of these late complications may further enhance the long-term success rate of renal transplantation.
