Abstract
The aim of the study was to assess the structure, volume, and function of the thyroid gland following kidney transplantation compared with those features of long-term transplant recipients as well as patients with normal native kidney function. Study group A consisted of 30 patients undergoing allogenic kidney transplantation, study group B included 30 long-term kidney transplant recipients who displayed stable renal function at 4 to 11 years following transplantation; control group C comprised 38 patients who were diagnosed or treated for reasons other than thyroid or renal insufficiency. Mean FT-3 concentrations in group A decreased from 2.19 pg/mL preoperatively to 1.52 pg/mL on the first posttransplantation day, returning to the preoperative values (2.06 pg/mL) at 30 days postoperatively. After 6 months the concentrations of thyroid hormones were similar to those among the long-term posttransplantation group (group B), although still lower than those in the control group. Mean thyroid volume in dialyzed patients was 17.10 mL; in the long-term group, 17.60 mL; and in the control group, 15.82 mL between groups that were not statistically significant. Abnormal structure of the thyroid gland was observed in 63% of group A (n = 19), 70% of group B (n = 21), and 29% of the control group. Significantly more abnormal thyroid gland structures were observed among dialyzed or transplanted patients. The thyroid volume was similar in all groups. Significant transient decrease in thyroid stimulating hormone (TSH) and free triidothyronine (FT-3) was not free thyroxine (FT-4) concentrations following kidney transplantation. Occasionally, increase accompanied by a change in FT-4 and TSH concentrations were observed, and antithyroid antibodies were detected only sporadically.
