Thyroid hormone analogue (TRIAC) therapy in resistance to thyroid hormone beta, reduces hyperthyroid symptoms, lowers circulating thyroid hormones and metabolic rate effectively, without adverse effects

Moran Carla , Lyons Greta , Watson Laura , Taylor Kevin , Oddy Sue , Halsall David , Chatterjee Krishna

Background: The treatment of Resistance to Thyroid Hormone beta (RTHb) is challenging because no therapy restores the euthyroid state in all tissues. Triac (triiodothyroacetic acid), a centrally-acting thyroid hormone analogue that preferentially activates thyroid hormone receptor beta, is reported to be beneficial in case reports or small case series.Methods: We have treated a cohort of adult RTHb patients with hyperthyroid symptoms with Triac for upto ...

Background: The treatment of Resistance to Thyroid Hormone beta (RTHbeta) is challenging because no therapy restores the euthyroid state in all tissues. Triac (triiodothyroacetic acid), a centrally-acting thyroid hormone analogue that preferentially activates thyroid hormone receptor beta, is reported to be beneficial in case reports or small case series. Methods: We have treated a cohort of adult RTHbeta patients, all with heterozygous mutations in ...

Resistance to Thyroid Hormone alpha (RTHα) is characterised by tissue-selective hypothyroidism with near-normal thyroid function tests, and is due to thyroid receptor α gene mutations. We sought to correlate the clinical characteristics and response to thyroxine treatment of two RTHα patients with the properties of their defective TRα proteins.Clinical, biochemical and physiological parameters were assessed in each patient at baseline...

Objectives: In 2011, we described the first case of Resistance to Thyroid Hormone due to a mutation in thyroid hormone receptor a (RTHα) in a six year old child with features of congenital hypothyroidism but near-normal thyroid function tests. Here, we report outcomes following twelve years of thyroxine therapy in this patient.Methods: Colonic contractility, intestinal transit time, growth, resting energy expenditure, heart rate and biochemical para...

Objectives: THRA mutations cause Resistance to Thyroid Hormone α (RTHα), an underdiagnosed disorder with hypothyroid features but near-normal thyroid function tests (TFTs). We developed a pathway, combining molecular analyses, new biomarkers and physiological measurements, to better diagnose and treat this disorder.Methods: Structural and functional analyses of THRA variants, discovered by next generation sequencing in specifi...
