Thyroid function in chronic renal failure after successful renal transplantation
Clinical Nephrology
|March 1, 1981
Summary
Patients with chronic renal failure after kidney transplant show higher total triiodothyronine (TT3) levels. Despite this, thyroid hormone levels remain normal, indicating a complex interplay of factors affecting thyroid function post-transplant.
Area of Science:
- Nephrology
- Endocrinology
- Transplantation
Background:
- Chronic renal failure (CRF) is linked to thyroid function abnormalities.
- Limited data exists on thyroid function in CRF patients post-successful renal transplantation.
Purpose of the Study:
- To investigate thyroid function in patients who have undergone successful renal transplantation for chronic renal failure.
Main Methods:
- Studied thyroid function in 13 patients post-renal transplant.
- Compared serum total triiodothyronine (TT3) levels with a control group.
- Assessed other thyroid function tests including TT4, FT4, FT3, TSH, TBG, and T3 resin uptake.
Main Results:
- Serum TT3 was significantly higher (P < 0.01) in the transplant group (136 +/- 30 ng/ml) compared to the control group (112 +/- 29 ng/ml).
- All patients were clinically euthyroid.
- Serum TT4, FT4, FT3, TSH, TBG levels, and T3 resin uptake were within normal ranges.
Conclusions:
- Successful renal transplantation in CRF patients is associated with elevated serum TT3 levels.
- The underlying mechanism for increased TT3 post-transplant remains unclear.
- Further research is needed to elucidate the pathogenesis of altered thyroid hormone levels in this population.
