Abstract:
The changes of thyroid hormones are expected in patients with chronic renal failure(CRF) because the kidney plays an important role in metabolism and excretion of thyroid hormones. In spite of many studies about this issue, there have not been full consensus about the nature and mechanism of thyroid hormone changes. We undertook the present study to reveal the dialysis effects on these hormones. We measured basal levels of serum total T3 (T3), total T4(T4), free T4(FT4), reverse T3(rT3) and TSH, and then calculated the ratio of T3/T4, rT3/T3 and rT3/T4. The following groups were identifed : Group I-10 cases of normal controls, Group II-18 cases of pre-dialysis or treated conservatively, Group III-20 cases treated by maintenance hemodialysis(HD), Group IV-18 cases treated by continuous ambulatory peritoneal dialysis(CAPD). Patients from group II, III and IV revealed significantly decreased levels of T3 and T4, and increased ratio of rT3/T4 in comparison to the control group(P<0.05). Especially, CAPD group revealed significantly increased levels of T4 and FT4 in comparison to HD group(P<0.05). In the long-term dialysis group(>36months), the mean concentrations of free T4 levels revealed signifcantly decreased in comparison to the short-term dialysis group(P<0.05). Thyroid dysfunction are observed in CRF patients with partial recovery after dialysis therapy. Especially, CAPD achieves significantly improved thyroid dysfunction compared to HD, but further study would be necessary.
