Filter by:this study may help the physicians to evaluate the practice of universal screening of sub-clinical hypothyroidism and thyroid-stimulating hormone level. Detection of sub-clinical hypothyroidism early in pregnancy through thyroid-stimulating hormone sampling in the first trimester will allow achieving proper management and better maternal and neonatal outcome of these patients.
Thyroid hormones (TH) can modify the functioning of the hypothalamic-pituitary-ovarian axis, affecting the functions of granulosa cells and the development and apoptosis of preantral follicles. TH receptors are present within the oocytes, and TH and anti-thyroid antibodies (ATA) are present in the follicular fluid. Improper thyroid function can cause ovulation disorders, luteal phase failure, impaired endometrial receptivity and result in implantation failures and recurrent miscarriages. While overt hypothyroidism is treated to improve fertility, the effect of subclinical hypothyroidism (SCH) and the presence of circulating ATAs on fertility and obstetric outcomes is uncertain and data on ovarian reserve rates are conflicting. Among the causes of ovulation disorders (group II according to the WHO classification), polycystic ovary syndrome (PCOS) dominates, found in 3-15% of women of reproductive age, and the remaining group of causes is the so-called Hypothalamic-Pituitary-Ovarian Axis Dysfunction (HPOD). The exact etiology of both entities is unknown.
Osteoporosis is a condition that describes compromised skeletal microarchitecture in general, with clinical signs of decreased bone mineral density. Patients with hypothyroidism are at increased risk for developing osteoporosis. Identifying whether multiple sclerosis patients have information and awareness about this disease is crucial. This study is aimed to investigate awareness and knowledge of osteoporosis in patients with hypothyroidism.
Type 2 Diabetes mellitus (T2DM) is a chronic disease with a high prevalence and several comorbidities impacting on public health and society. Among the complications of T2DM it has been showed a high prevalence of hypogonadotropic hypogonadism. Even if hypogonadism is associated to a worse metabolic profile and cardiovascular risk, it is discussed whether and when to treat this potentially reversible form associated to diabetes. In fact, the pathogenic mechanism of this condition in diabetic patients is not fully understood, and its clinical correlates, including the prevalence of other possible associated hypothalamic-pituitary axes dysfunctioning, questioned. The aim of the present study is to assess with an observational, cross sectional study on a large series of type 2 diabetic patients, enrolled consecutively: all the suspected etiologies of this complication in one single evaluation (both acquired and genetic congenital predisposition), its clinical correlates and the real prevalence of the disease using the lastly validated criteria for late onset hypogonadotropic hypogonadism.
Thyroid disease affects almost a quarter of a billion individuals worldwide and more than 50% of them being not aware of this condition. The commonest thyroid disease is iodine deficiency related thyroid dysfunction with nearly 2 billion people around the globe at risk with insufficient iodine intake. Autoimmune thyroid disorders are commonest cause of thyroid dysfunction in iodine sufficient parts of the world. Sub-optimally or untreated hypothyroidism can lead to cognitive decline, dyslipidemia, hypertension, infertility as well as cardiovascular and neuromuscular problems. The prevalence of hypothyroidism can vary in general population with up-to 5.3% people with overt hypothyroidism based on studies from the West, with estimated 10% of the population having subclinical hypothyroidism globally. In the gulf region however, there are no national studies that provide insight into exact prevalence of hypothyroidism, however some cross-sectional screening studies indicate frequency of hypothyroidism to be as high as 5-10%. Levothyroxine is a synthetic hormone with structure similar to naturally occurring thyroxine, and it is used as replacement monotherapy of hypothyroidism. It is mainly absorbed via small intestine. The optimal daily levothyroxine dosage requirement is 1.6 microgram/kg body weight/day, which can normalize TSH in most patients, however many studies indicate that nearly half the patient on replacement therapy may not attain a normal TSH and require further doses, possibly due to interference or malabsorption. Multiple dose change and repeated diagnostic procedures in these patients can not only increased health costs but increased of ensuing complications secondary to sub-optimally controlled hypothyroidism. Instead of increasing levothyroxine doses and getting variable response, recent study have shown improvement in thyroid function by adding on vitamin C alongside levothyroxine dose, albeit only in a specific subset of patient having gastritis. The effect of Vitamin C on improving levothyroxine also been shown to be effective over a short period in a non-randomized, non-controlled setting. Our study aims to investigate whether addition of vitamin C to levothyroxine can improve the biochemical and clinical thyroid status in a randomized controlled setting.
The North Star study is a multi-center, Phase 2, double-blind, randomized, parallel group clinical study to evaluate the safe and effective dose conversion from Levothyroxine to North Star therapy.
Hypothyroidism refers to the common pathological condition of thyroid hormone deficiency. The annual incidence of hypothyroidism is 3.5 per 1000 in women and 0.6 in per 1000 men. Hypothyroidism is seen 5-8 times more frequently in women than in men. Patients with hypothyroidism have a higher prevalence of cardiovascular risk factors and often have metabolic syndrome features such as hypertension, increased waist circumference, and dyslipidemia. Other signs and symptoms include bradycardia, slow speech, swelling in the eyes and face, weight gain, decreased sweating, hair loss, pallor, forgetfulness, decreased concentration, depression, irritability, tongue growth, loss of appetite, palpitations, decreased hearing, menstrual irregularities, muscle pains, and cramps. Depending on all these signs and symptoms, hypothyroidism can negatively affect the quality of life of individuals. Therefore, it is essential to reduce symptoms and to improve patients' abilities to manage them. It is stated that the appropriate use of mobile health applications helps the patient to make informed decisions about health management and treatment. Therefore, this study plans to investigate the effect of mobile technology on symptom management in individuals with hypothyroidism, whose symptoms range from mild to severe.
Newborn screening (NBS) is a global initiative of systematic testing at birth to identify babies with pre-defined severe but treatable conditions. With a simple blood test, rare genetic conditions can be easily detected, and the early start of transformative treatment will help avoid severe disabilities and increase the quality of life. Baby Detect Project is an innovative NBS program using a panel of target sequencing that aims to identify 126 treatable severe early onset genetic diseases at birth caused by 361 genes. The list of diseases has been established in close collaboration with the Paediatricians of the University Hospital in Liege. The investigators use dedicated dried blood spots collected between the first day and 28 days of life of babies, after a consent sign by parents.
Hypothyroidism is common, affecting 5% of the general population, for which levothyroxine (LT4) monotherapy is the standard treatment. Despite normalized serum thyroid hormone levels, 10-15% of LT4 treated patients have various persistent complaints, the most important of which is tiredness. This could be explained by the fact that physiological T4/T3 ratios cannot be reached with LT4 monotherapy, as in a healthy individual T3 is not only derived from T4/T3 conversion but is also directly produced by the thyroid itself. Studies have reported contradicting results as to whether addition of liothyronine (LT4/LT3 combination therapy) in patients with persistent tiredness on LT4 monotherapy is effective or not. Studies have suggested higher effectiveness in patients carrying genetic variation in the type 2 deiodinase (DIO2-rs225014) and monocarboxylate transporter 10 (MCT10-rs17606253) genes. Objective: To investigate whether addition of liothyronine (LT4/LT3 combination therapy) in in patients with persistent tiredness on LT4 monotherapy is effective or not in relieving tiredness.
The purpose of this retrospective study was to clarify the possible risk factors of early hypothyroidism after RAI therapy in Graves' disease.
