| NCT01832753 ↗ | Treatment Trial of Subclinical Hypothyroidism in Down Syndrome | Completed | Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) | N/A | 2013-01-01 | The purpose of this research study is to learn about the effects of treating subclinical hypothyroidism (SCH) with thyroid hormone replacement in children and adolescents with Down syndrome (DS). We hypothesize that treatment of SCH with thyroid hormone replacement will improve cardiometabolic health and quality of life. |
| NCT01832753 ↗ | Treatment Trial of Subclinical Hypothyroidism in Down Syndrome | Completed | Children's Hospital of Philadelphia | N/A | 2013-01-01 | The purpose of this research study is to learn about the effects of treating subclinical hypothyroidism (SCH) with thyroid hormone replacement in children and adolescents with Down syndrome (DS). We hypothesize that treatment of SCH with thyroid hormone replacement will improve cardiometabolic health and quality of life. |
| NCT02567877 ↗ | Is Levothyroxine Alone Adequate Thyroid Hormone Replacement? | Recruiting | Charite University, Berlin, Germany | 2016-11-01 | Patients taking thyroid hormone replacement after thyroid removal surgery often report feeling differently than they did prior to taking thyroid hormone. The symptoms can include fatigue, worsening mood or subjective "brain fog" where the patient feels like their thinking is just not as sharp as it was previously. Multiple studies have found that patients taking thyroid hormone replacement have a diminished quality of life compared to matched controls. Previous studies have suggested that the type of deiodinase (DIO) polymorphism a patient has, which is responsible for converting the thyroid hormone T4 into the more biologically active T3, may contribute to their overall cognition and sense of well-being. The Investigators aim to determine if the type of deiodinase polymorphism a patient has contributes to the patient's cognition and overall sense of well-being after surgery and thyroid hormone replacement. Objective: Determine if patients with the deiodinase type 2 CC polymorphism have objective differences in working memory (N-back test is primary endpoint), cognitive function and sense of well-being after thyroidectomy when placed on standard thyroid hormone replacement therapy. Hypotheses: (1) Patients with the deiodinase type 2 CC polymorphism will have worse working memory (N-back test is primary endpoint), cognitive function and sense of well-being on standard thyroid hormone replacement therapy after thyroidectomy compared with before thyroidectomy. (2) Patients with the deiodinase type 2 TT or TC polymorphism will have no differences in working memory, cognitive function or sense of well-being on standard thyroid hormone replacement before and after thyroidectomy. | |

| NCT02917863 ↗ | Randomized Crossover Trial for the Evaluation of the Possible Effects in the Intestine of Two Different Pharmaceutical Forms of L - Thyroxine in Patients With Primary Acquired Hypothyroidism | Unknown status | Meyer Children's Hospital | Phase 4 | 2016-05-01 | Thyroid disorders, in particular hypothyroidism, are associated with gastrointestinal impairment, such as celiac disease. A study reported an increased prevalence of celiac disease in a large cohort of children affected by congenital hypothyroidism, underlying the relationship between these two conditions. The hypothesis of our study is that the onset of celiac disorder may be related to the gut concentration of thyroid hormone (TH) in hypothyroidism patients treated with replacement therapy. In fact, TH replacement therapy showed a low bioavailability with a consequent high gut concentration. Two different pharmaceutical formulations (liquid and solid, per os) are available. The liquid one has a better absorption profile and bioavailability than the solid; therefore, it is associated with a low TH intestinal concentration. According to our hypothesis, the solid TH formulation could increase the microbial diversity in the gut instead of the liquid form, due to the high local TH concentration. Based on these findings, the purpose of this study is to evaluate the effect of two different pharmaceutical formulations of TH on the gut in terms of modification of gut microbiota, inflammatory parameters and gut absorption. |
