introduction: hypothyroidism is diagnosed by elevated thyroid stimulating hormone (tsh) and normal or decreased serum levels of t4 or t3, and is associated with a wide range of m etabolic abnormalities, including anemia. this clinical study aimed to assess the improvement of anemia in patients with primary hypothyroidism following administration of levothyroxine in iranian population. materials...

Background: Smoking can cause thyroid disorders; the aim of the present study was to investigate the association between smoking status and changes in thyroid hormone levels among adult males during a decade long follow-up of in the Tehran Thyroid Study (TTS). Methods: Data of 895 adult males (smokers=115, non-smokers=691, ex-smokers=89) participants of the TTS without any previously known thy...

Introduction: According to some studies, Ramadan fasting causes minimal changes in the levels of thyroid hormones. The present study aimed to evaluate the impact of Ramadan fasting on the levels of thyroid hormones in fasting women with hypothyroidism and levothyroxine intake. Methods: Serum levels of free thyroxine (T4) and thyroid-stimulating hormone (TSH) we...

 Background: To investigate thyroid function in preeclamptic patients in comparison with normal pregnant women. Methods: In this analytical cross-sectional study free Thyroxine (T4), and Thyroid Stimulating Hormone (TSH) levels were measured in 100 preeclamptic patients and were compared with Free T4 and TSH levels in 101 normal pregnant women in their third trimester of pregnancy. Patient...

BACKGROUND It is now recognized that TSH can act on targets other than the thyroid, including the liver. Elevated serum TSH levels in euthyroid subjects were recently reported to correlate with high values of serum proprotein convertase subtilisin/kexin type 9 (PCSK9). This protein, expressed and secreted by hepatocytes, promotes higher LDL-cholesterol levels. We tested whether an acute increas...

BACKGROUND Thyroid hormone is a central regulator of body functions. Disorders of thyroid function are considered to be a cause of electrolyte disorders. Only few data on the association between thyroid function and electrolyte disorders exists. METHODS In the present retrospective analysis data from all patients admitted to the Department of Emergency Medicine of a university hospital who ha...

This study investigated whether high-normal thyrotropin (TSH) levels are associated with metabolic syndrome in euthyroid Chinese people≥40 years old. Clinical and metabolic factors were assessed in 2,356 subjects (40-77 years old) with TSH levels in the normal range (0.35-5.00 mU/L). Using 2.50 mU/L as the cut-off point of TSH level within the normal range, we divided subjects into the high-TSH...

BACKGROUND Impaired left ventricular (LV) diastolic function is a common pathophysiological feature of patients with hypertrophic cardiomyopathy (HCM). High-normal thyrotropin (thyroid-stimulating hormone, TSH) levels may alter the performance of the left ventricle. AIM To ascertain whether the severity of impaired LV diastolic function in HCM patients might worsen with elevating TSH levels w...
