| pubmed-article:16515117 | pubmed:abstractText | Thyroid hormone resistance (RTH) is a rare autosomal dominant disorder, characterized clinically by goiter and biochemically by elevated circulating free thyroid hormone levels in the presence of measurable serum thyroid-stimulating hormone (TSH) concentrations. About 85% of patients with RTH harbor mutations in thyroid hormone receptor [beta] (TR[beta]). Even rarer is pituitary thyroid resistance syndrome. We report a case of a 35-year-old man who presented with hypermetabolic symptoms with elevated levels of thyroid hormones, associated with nonsuppressed thyrotropin (TSH). When treated with anti-thyroid drugs, his thyroid hormone levels normalized and TSH increased, suggesting thyroid resistance at the pituitary level. | lld:pubmed |
