OBJECTIVE To determine whether alterations in pulmonary function takes place in subclinical hypothyroidism by examining the diffusion lung capacity and muscle strength of such patients. METHODS This is a descriptive study conducted in 2009 at Haseki Training and Research Hospital, Istanbul, Turkey. Hundred and twenty-six patients with subclinical hypothyroidism and 58 age and sex matched indi...

Preliminary data have suggested that female infertility due to corpus luteum insufficiency may be caused by subclinical hypothyroidism [exaggerated thyroid-stimulating hormone (TSH) response to thyrotrophin-releasing hormone (TRH) stimulation]. L-Thyroxine supplementation has been recommended to achieve pregnancies in subclinical hypothyroid women. This controlled study was carried out in order...

The aim of this review is to expose different opinions in the literature on influence TH and TSH autonomic vegetative regulation cardiovascular function metabolism marked subclinical hypothyroidism (sHT). Hypothyroidism causes changes hemodynamics lipid metabolism, which are predisposing risk factors for diseases. Subclinical proceeds asymptomatically but there system its regulation, as well a ...

The aim of this study was to compare the prevalence of subclinical and overt hypothyroidism based on local population-specific reference intervals versus arbitrary cutoffs that are not specific for the population studied or the assay used, during pregnancy in an area of iodine sufficiency. We tested a total of 203 pregnant women in the first trimester of pregnancy, and followed their status in ...

Accurate diagnosis and treatment of subclinical hypothyroidism (SCH) is challenging in clinical practice because normal limits of TSH differs in various studies [1]. Subclinical Hypothyroidism (SCH) is defined as mild elevation in serum TSH levels with normal fT3 and fT4 concentration. The prevalence of this disease is 4-10% in the general population of United States. Up to 20 % women older tha...

Normal level of thyroid hormones is important for normal hepatic function and thyroid dysfunction may modulate metabolic function of liver. The purpose of this study is to determine whether liver function is associated with subclinical and overt hypothyroidism. Thyroid and liver function tests were evaluated in 47 patients with overt (TSH ≥10.0 mIU/L) and 77 patients with subclinical hypothyroi...

BACKGROUND There have been few large epidemiological studies examining the association between thyroid dysfunction and cardiovascular disease. In particular, it is uncertain if subclinical hypothyroidism is a risk factor for cardiovascular disease. METHODS Serum thyrotropin and free thyroxine concentrations were measured in 2108 archived serum samples from a 1981 community health survey in Bu...
