Active clinical trials for "Hypothyroidism"

Study design: Phase II study, randomized, double-blind, unicentric, two-arm, placebo-controlled clinical trial. Methods and participants: Patients with Chronic Kidney Disease G2-G5 with proteinuria without renal replacement therapy, who come to the clinic of renal health clinic of the Fray Antonio Alcalde civil hospital. As criteria for non-inclusion, need for dialysis, primary hypothyroidism or pre-existing thyroid disease, ischemic heart disease in a period less than 6 months, arrhythmia, pregnancy, use of drugs that interact with synthesis of thyroid hormones, do not accept informed consent, thyroid stimulating hormone (TSH) <2.5 uiml / L or TSH> 10 uiml / L.

This study evaluates the effects of an inhaled blend of essential oils on fatigue scores among women who have hypothyroidism. Half of the participants will receive an essential oil blend to inhale daily for two weeks while the other half will serve as controls and inhale a carrier oil.

The purpose of this study is to determine whether treating women, who are diagnosed with a mild imbalance of thyroid hormones during pregnancy, with thyroid hormone replacement affects their children's intellectual development at 5 years of age.

Our aim is to compare the safety and efficacy of 2 different empiric levothyroxine dose adjustment recommendations to be made at the first confirmation of pregnancy in women with a history of hypothyroidism. Subjects will be women with a prior diagnosis of hypothyroidism who are taking thyroid hormone replacement and who are less than 8 weeks pregnant. Upon confirmation of pregnancy, subjects will be randomized to increase their weekly thyroid hormone dose by either 2 or 3 tablets (28 or 42%). Thyroid function will be evaluated every two weeks in the first 20 weeks and then again at week 30 and post-partum. Primary endpoints will be the proportion of women in each group who remain euthyroid throughout the first trimester and throughout pregnancy.

The aim of the study is to evaluate the peripheral tissue response to the combined administration of levothyroxine (LT4) and liothyronine (LT3) in hypothyroid patients with residual thyroid function virtually absent (thyroidectomized). Cases will be treated with LT4+LT3, at personalized doses according to clinical guidelines and respecting the circadian rhythmicity of LT3 and the physiological T3/T4 ratio. Controls will be treated with LT4 and placebo. Treatment duration: 24 weeks. The primary endpoint will be the peripheral effect of thyroid hormones. The secondary endpoints are bone and metabolic modifications, and changes in quality of life. Moreover any changes of outcomes related to polymorphisms of genes involved in thyroid hormones metabolism will be evaluated.

The investigators propose the following hypothesis: discontinuation of levothyroxine (LT4) for veterans with subclinical hypothyroidism (SCH) will be feasible, acceptable, and safe and will not negatively affect their Quality of Life (QoL). The investigators aim to 1) evaluate the feasibility of LT4 discontinuation among veterans with SCH and determine the changes in QoL measures, lipids, and adverse events, and 2) assess the acceptability of LT4 discontinuation among veterans with SCH and LT4 prescribing clinicians.

Subclinical hypothyroidism (SCH) is common among the elderly population and has been associated with neuromuscular impairment. Muscular symptoms such as weakness, myalgia and cramps are more often reported by SCH patients compared to euthyroid controls. Sarcopenia is the age-related loss of muscular mass and function and its assessment includes three dimensions (muscle quantity, muscle strength and physical performance). To date, evidence is lacking about the effect of thyroid hormone replacement on skeletal muscle impairment in SCH patients. The aim of the study is therefore to evaluate the impact of levothyroxine therapy on sarcopenia measures in SCH. This is a nested substudy within two large international multicenter randomized controlled trial of elderly participants with SCH (TRUST Study, clinicaltrials.gov ID NCT 01660126; and IEMO Study, Netherland Trial Register ID NTR3851). Those two trials shared a very similar study design. The cohorts will therefore be analyzed as a single study population.

Muslims all over the world fast during the month of Ramadan from dawn until dusk. There is little data regarding the best timing of levothyroxine intake during the month of Ramadan where taking it on an empty stomach represents a challenge to most patients.This study aims to compare two-time points of levothyroxine intake during Ramadan in terms of change in thyroid stimulating hormone (TSH), compliance and convenience.

Study the pattern of congenital hypothyroidism in newborns after positive newborn screening results. Assess the characteristics of the cases (permanent congenital hypothyroidism and transient neonatal hyperthyrotopinemia).

Subclinical hypothyroidism (SCH) is a common condition among older men and women. Although by definition SCH comprises biochemically mild thyroid hormone deficiency without overt symptoms, it is a possible contributor to multiple problems in older age. Thyroid hormone has effects on numerous physiological systems, including the vascular tree, heart, skeletal muscle and brain. Therefore, thyroxine substitution to overcome thyroid hormone deficiency has the potential to give multisystem benefits to older people with SCH. Small studies have reported reduced atherosclerosis and improved heart function with thyroxine replacement, but no large clinical trials have been performed. Therefore the available evidence is limited, leading to major variations in guidelines and clinical practice, with uncertainty regarding the indications for screening and treatment. The investigators propose a multicentre randomised placebo controlled trial to assess the impact of thyroxine replacement in a minimum of 540 older adults (maximum 750) with persisting SCH (excluding those in whom it is a temporary phenomenon who are unlikely to benefit). The investigators will include older men and women with a wide age range and of varying health status. Outcomes include health related quality of life, muscle strength, executive cognitive function and cardiovascular events, with a minimum of 1 year of follow up. Blood and urine samples will be stored in a biobank, to allow future research on causes of ill health in older people with SCH. The investigators have the support of patient advocacy groups and a consortium with the wide range of expertise and experience required to conduct large scale multicentre clinical trials. The proposal explores the multisystem and quality of life benefits to older people of a tailored approach to management of SCH. This clinical trial should definitively clarify whether thyroxine treatment for SCH provides benefits that are relevant for patients. This trial will provide strong evidence with the potential to improve clinical practice, reduce health care costs and promote healthy ageing of older adults.
