초록 Introduction: The abnormalities in thyroid function, especially triiodothyronine (T3) levels, are observed in patients with chronic kidney disease and end stage renal disease. Few previous studies evaluated the correlation between thyroid function after kidney transplantation and various clinical outcomes, in particular, in Asian patients. Methods: During the period of January 1997 to January 2012, the data about a total of 400 kidney transplant recipients who had thyroid function test measured within 5 years after kidney transplantation was analyzed through the retrospective review of electronic medical records of two medical centers. Results: Posttransplant thyroid-stimulating hormone (TSH) level was 1.9±4.2 μIU/mL, free thyroxin (fT4) level was 1.3±0.4 ng/dL, and T3 level was 112.4±34.1 ng/dL. After follow up duration of 77.3±53.0 months, 41 patients (10.3%) were diagnosed allograft failure. In Cox-regression analysis model, posttransplant T3 level was negatively correlated with graft failure (HR 0.98; 95% CI 0.97-0.99; p=0.001), however, post-transplant TSH and fT4 level were not associated. Divided to tertiles of T3 level, the risk for development of graft failure was the highest in the lowest group of T3 level (HR 6.25; 95% CI 1.74-22.44; p=0.005). After adjusting other risk factors for graft failure, posttransplant T3 level was also significantly associated with kidney allograft failure. In Kaplan-Meier curves, in patients with lower T3 level had the higher risk for allograft failure (Log Rank p=0.002). Conclusions: Triiodothyronine level measured after kidney transplantation is an independent risk factor for allograft failure. Regular measurement and monitoring of thyroid function should be the critical focus of post-transplant care.
