Filter by:This project analyzes the relationship between type 2 deiodinase gene polymorphism and the TSH inhibitory treatment efficacy in thyroid cancer patients with thyroidectomy, and explored the factors influencing TSH inhibitory treatment efficacy. It further explores whether patients with diO2-Thr92ALA genotype or DIO2 Orfa-Gly3ASP genotype should choose T4+T3 treatment, and the effect of different treatment options on the quality life of patients.
Recently, Zaborek et al. raised a Poisson regression model for levothyroxine(LT4) dosing scheme to predict individual dose of LT4 after thyroidectomy: daily LT4 dose=e[2.02+0.01(W)-0.0037(A )-0.098(F)-0.01(B)+0.007(T)+0.108(I)-0.014(M), where W is the weight of the patient (Kg), A is the age of the patient (years), and F is the gender (for women 1, male is 0), B represents the patient's body mass index (BMI), T represents the preoperative TSH level, I represents whether the patient takes iron preparations (1, if not 0), M represents whether the patient takes multivitamins/minerals (1, if not 0). We demonstrated its value with our retrospective data in our center. Therefore, we intend to carry out this randomized controlled trial in order to further evaluate the model. The clinical significance of this method can provide a basis for the future use in clinical optimization of individualized dosing.
This is a multi-center, prospective, parallel-group, open-label, randomized clinical study in one hundred and twenty-six (126) neonates and infants diagnosed with CH. Subjects will be randomized in a 2:1 ratio to Treatment (Tirosint®-SOL) or Control (conventional therapy with levothyroxine sodium crushed tablets).
Assessment of quality of life among hypothyroid patients in Assiut University Hospital
The study series consists of three studies with the aim to assess the incidence, prevalence, risk factors, comorbidities and management of patients with alopecia areata in Czech Republic based on the patients and registry of a dermatology clinic of a metropolitan hospital.
The main focus of the study is the assessment of hormonal function in the course of COVID-19 infection with special regard for trends predicting clinical events defined as primary endpoints of the study.
Thyroid function test are performed in the well baby nursery to newborn infants of mothers with hypothyroidism, or as part of neonatal jaundice investigation. As thyroid function test are also part of the national screening test program, the investigators raised the option that the above management is unnecessary, and managed a study to investigate it.
Dietary intervention with Únicla dairy products, naturally enriched with selenium and omega-3 fatty acids, may improve thyroid-stimulating hormone (TSH) levels in women with subclinical hypothyroidism
The aim of this study is to evaluate the relationship between serum rT3 (serum reverse triiodothyronine) concentrations, T3/T4 (triiodothyronine/thyroxine) ratio, and persistent symptoms /quality of life in treated hypothyroid patients. Investigators are going to measure TSH (thyroid stimulating hormone), free-T3, free-T4, reverse-T3 levels, biochemical markers of hypothyroidism and quality of life (assessed by validated questionnaires).
Hypothyroidism is a common disease that is successfully treated with the replacement of thyroid hormones in the form of levothyroxine. Levothyroxine is drug used in the first line of substitution therapy because it appropriately mimics physiological secretion of thyroxine (T4) and its peripheral conversion to triiodothyronine (T3). However, due to its narrow therapeutic index, and because it is administered at very low doses (micrograms - μg), it is particularly sensitive to the absorption phase interactions, which are due to its narrow therapeutic index, mainly clinically significant. In pregnancy, one of the goals is to maintain the values of thyroid stimulating hormone (TSH) in the lower part of the reference interval (below 2,5 milli-International units - mIU/L) for a proper child development. Also, due to increased nutritional needs during pregnancy, nutritional supplements are commonly used by pregnant women on their own initiative, but also often recommended by healthcare personnel. Reviewing the literature, we did not find high quality evidence to suggest the existence or to refute the interaction between dietary supplements for pregnant women and the absorption of levothyroxine. The aim of this study is to investigate this potential interaction between dietary supplements used in pregnancy and levothyroxine absorption in order to test the safety of the use of these preparations in pregnant women who are on replacement therapy with levothyroxine.
