| Popis: | Thyroid hormone (free and total thyroxine, total 3,5,3'- and 3,3'5'-triiodothyronine, thyroxine-binding globulin, thyrotropin) serum concentrations were measured in 107 uremic patients of 4 hemodialysis centers, in order to study the prevalence of hypothyroidism in hemodialysis patients. In accordance with the clinical impression there was no laboratory evidence of thyroid dysfunction. In spite of the fact that all patients had the expected low-T3 syndrome, there were highly significant differences between the mean thyroid hormone concentrations of the 4 different centers. The center with the highest thyroid hormone levels (all normal except for borderline low 3,5,3'-triiodothyronine) also had the lowest urea levels, indicating the relatively best metabolic control. One center had significantly lower hormone levels than the other 3 centers (all hormones except free thyroxine were below normal) with urea levels that did not differ significantly from one of these centers. A retrospective analysis of patients and of the techniques of dialysis of 3 centers excluded factors like heparin or the length of time on dialysis to be the reason for the low values of this center. Finally, only the significantly higher proportion of unsuccessfully transplanted patients and some technical differences (lack of water treatment, regenerated cellulose as dialyser membrane, and low magnesium content in the dialysate) unique for this center remained as possible factors that may speculatively explain the observed low thyroid hormone values.(ABSTRACT TRUNCATED AT 250 WORDS) |
