| pubmed-article:2507207 | pubmed:abstractText | Serum TBG concentrations were evaluated in 34 patients on regular hemodialysis. Mean serum TBG level measured by two different radioimmunoassays was markedly decreased (1.24 +/- 0.08 mg/dl - normal limits 1.6-2.4 mg/dl). Twenty-seven (79%) patients had values below 1.6 mg/dl, which contrasted in 21 of them with a lack of reciprocal elevation of T3RU values. By contrast, T4-binding capacity of TBG measured in 14 patients with low TBG concentration was normal, suggesting that the low TBG values were an artefact resulting from an altered immunoreactivity of the protein. In 2 patients with low TBG while on hemodialysis, TBG levels increased significantly after renal transplantation. This suggests that the "low TBG syndrome" (altered immunoreactivity in the face of normal T4-binding capacity) observed in patients on chronic hemodialysis is a consequence of uremia. | lld:pubmed |
