Hypothyroidism, characterised by low/normal free thyroxine (FT4) and free tri-iodothyronine (FT3) with elevated thyroid-stimulating hormone (TSH), is a well-known complication of nephrotic syndrome (NS). This is a common feature of primary and secondary glomerular diseases and comprises loss of protein in the urine and increased urinary excretion of thyroid hormones and thyroxine-binding globulin. With a normal thyroid reserve, this scenario is associated with the development of subclinical hypothyroidism, with a slight increase in TSH and normal free fractions...

BACKGROUND: Subclinical hypothyroidism (SCH) is a common condition in elderly people, defined as elevated serum thyroid-stimulating hormone (TSH) with normal circulating free thyroxine (fT4). Evidence is lacking about the effect of thyroid hormone treatment. We describe the protocol of a large randomised controlled trial (RCT) of Levothyroxine treatment for SCH. METHODS: Participants are community-dwelling subjects aged ≥65 years with SCH, diagnosed by elevated TSH levels (≥4...

BACKGROUND: Radioiodine ((131) I) is effective treatment for hyperthyroidism in cats, but optimal dose to restore euthyroidism without inducing hypothyroidism is unclear. Treatment-induced hypothyroidism can lead to azotemia and reduced duration of survival. OBJECTIVE: To compare efficacy and short-term outcomes of low-dose (131) I versus higher, standard-dose (131) I as treatment for hyperthyroidism. ANIMALS: A total of 189 client-owned cats undergoing (131) I treatment for mild-to-moderate hyperthyroidism (serum T4 ≥ 4...

OBJECTIVE: There remains controversy over how women with abnormal thyroid function tests in pregnancy should be classified. In this study we assessed the proportion of women with thyroid stimulating hormone (TSH)≥2.5mU/l in a large obstetric cohort, and examined how many have gone on to develop thyroid disease in the years since their pregnancy. STUDY DESIGN: 4643 women were recruited and samples taken in early pregnancy between 2007 and 2010. Thyroid function tests were analysed in 2014; in women with raised TSH computerised health records and prescription databases were used to identify thyroid disease detected since pregnancy...

AIM: In a screening study on people of working age the prevalence of morphological thyroid disorders was 33.1 %. It is not known precisely whether this further increases after retirement. The present study aimed to establish whether the increase in the prevalence of morphological and functional thyroid disorders continues beyond working age in elderly citizens. METHODS: 223 participants were recruited in an institute for geriatric rehabilitative medicine. All patients were screened by thyroid ultrasound, measurement of serum levels of thyroid hormones and thyroid related autoantibodies as well as measurement of urinary iodine excretion...

Contrasting results have been reported about the prevalence of thyroid autoimmunity (AT) and dysfunction (TD) in patients with psoriatic arthritis (PsA). In this study, we pointed to evaluate the incidence of new cases of clinical and subclinical TD in a broad group of patients with PsA versus a control group, matched by age and gender belonging to the same geographic area. PsA patients with TD were excluded firstly, and new cases of thyroid disorders were evaluated in 97 PsA patients and 97 matched controls, who had comparable iodine intake (median follow-up of 74 months in PsA versus 92 in controls)...

BACKGROUND: Subclinical hypothyroidism (SCH) and chronic autoimmune thyroiditis (CAT) are linked to an increased risk of atherosclerosis and coronary heart disease (CHD). The aim of this study was to look for positive markers of CHD and correlations with thyroid blood tests in patients with SCH or CAT, but no symptoms of CHD, so as to identify CHD risk conditions that otherwise would likely be missed. METHODS: We measured a series of thyroid, clinical-metabolic and cardiovascular parameters in 30 consecutive endocrinology patients enrolled in our ambulatory endocrinological referral center of "Sapienza" University of Rome...

This study explored the effects of levothyroxine (L-T4) replacement therapy on pregnancy outcomes in patients with subclinical hypothyroidism (SCH). We analyzed the effects on pregnancy outcomes with respect to gestational week when the desired thyroid-stimulating hormone (TSH) level was reached as well as the length of time required to reach the target level during L-T4 treatment. This study enrolled 457 patients diagnosed with SCH upon initial thyroid function screening. Subjects were assigned to the treatment group (N = 184), and the control group (N = 273)...

BACKGROUND: Despite some studies indicating that thyroid antibody positivity during pregnancy has been associated with adverse pregnancy outcomes, evidence regarding the effects of levothyroxine (LT4) treatment of euthyroid/subclinical hypothyroid pregnant women with autoimmune thyroid disease on pregnancy outcome is limited. We aimed to assess whether pregnant women with autoimmune thyroid disease, but without overt thyroid dysfunction are affected by higher rates of adverse pregnancy outcomes...

CONTEXT: Overt hypothyroidism accelerates the cardiovascular disease. Subclinical hypothyroidism (SCH), being considered as a preclinical state, impacts on cardiovascular status is not clear. AIMS: This study was aimed at assessing cardiac risk stratification by Framingham risk scoring (FRS) and coronary coronary artery calcium score (CACS) by noncontrast cardiac computed tomography in SCH. STUDY DESIGN: Observational study. SUBJECTS AND METHODS: We enrolled thirty treatment-naive SCH patients (aged 30-60 years with no serious concurrent medical conditions), thirty euthyroid (age, sex, and body mass index-matched) controls, and ten healthy controls...

Thyroid hormones influence renal development, kidney hemodynamics, glomerular filtration rate and sodium and water homeostasis. Hypothyroidism and hyperthyroidism affect renal function by direct renal effects as well as systemic hemodynamic, metabolic and cardiovascular effects. Hypothyroidism has been associated with increased serum creatinine and decreased glomerular filtration rate. The reverse effects have been reported in thyrotoxicosis. Most of renal manifestations of thyroid dysfunction are reversible with treatment...

BACKGROUND: Selenium (Se) is a trace element that plays key roles in thyroid physiology. Se deficiency is associated with increased risk of thyroid disease. Some evidence suggests that Se supplementation may be beneficial in autoimmune thyroid disease (either hypo- or hyperthyroidism). OBJECTIVES: We sought to examine the use of Se in daily clinical practice among Italian endocrinologists. METHODS: Members of the Associazione Medici Endocrinologi (AME) were invited to participate in a web-based survey investigating the use of Se in different clinical conditions...

Myocardial and vascular endothelial tissues have receptors for thyroid hormones and are sensitive to changes in the concentrations of circulating thyroid hormones. The importance of thyroid hormones in maintaining cardiovascular homeostasis can be deduced from clinical and experimental data showing that even subtle changes in thyroid hormone concentrations - such as those observed in subclinical hypothyroidism or hyperthyroidism, and low triiodothyronine syndrome - adversely influence the cardiovascular system...

INTRODUCTION: One of the more specific assessments of the metabolic status of bone in normal and in disease conditions is the measurement of bone specific alkaline phosphatase or ostase. The measurement of serum ostase has several advantages over the measurements of other bone parameter. Because of its relatively long half-life, in-vivo (1 to 3days), it is relatively unaffected by diurnal variation. AIM: To find the correlation of serum ostase level in hyper and hypothyroid cases and also to study the validity of routine estimation of serum ostase in hyper and hypothyroid cases so as to monitor the base level bone health on presentation...

Subclinical hypothyroidism (SCH) represents a mild or compensated form of primary hypothyroidism. The diagnosis of SCH is controversial, as its symptoms are non-specific and its biochemical diagnosis is arbitrary. The treatment of SCH was examined among non-pregnant adults, pregnant adults and children. In non-pregnant adults, treatment of SCH may prevent its progression to overt hypothyroidism, reduce the occurrence of coronary heart disease, and improve neuropsychiatric and musculoskeletal symptoms associated with hypothyroidism...

The incidence of subclinical hypothyroidism (SCH) in pregnancy was classically thought to be low; however, with new definition of normal TSH range in pregnancy, there has been an increase in the percentage of women who meet classification for SCH. The diagnosis of SCH is important not only for monitoring for maternal conversion to overt hypothyroidism, but also for identifying obstetric and neonatal outcomes related to SCH. Although there have been proven associations between maternal overt hypothyroidism and adverse obstetric and neonatal outcomes, there has been conflicting data on the correlation between SCH and these outcomes...
