Levels of thyroid hormones, serum thyroxine, triiodothyronine (T3), free thyroxine (FT4), free triiodothyronine (FT3) and thyrotropin (TSH) were measured in 55 patients with liver cirrhosis using radioimmunoassay techniques. Results were compared with 78 controls. The mean serum concentration of T3, FT3 and FT4 were significantly decreased in cirrhotics, while no significant change was noted in...

UNLABELLED Low triiodothyronine (T3) concentrations in the presence of normal thyroxine (T4) and TSH levels, referred to as the low T3 syndrome (LT3S), are common. LT3S may be caused by starvation, various non-thyroidal illnesses (NTIs) and some medications. Reverse T3 (rT3) concentrations are elevated in the more severely ill, and they characteristically fail to respond to exogenous levothyrox...

BACKGROUND Low birth weight has been linked with changes in thyroid function in adulthood, but it is unknown whether fetal programming or underlying genetic and environmental factors explains the association. We hypothesized that birth weight influences the pituitary-thyroid set point in adults. METHODS A total of 152 birth weight-discordant monozygotic twin pairs with a median age of 57 year...

OBJECTIVES In recent years, the widespread use of mobile phones has lead to a public debate about possible detrimental effects on human health. In spite of years of research, there is still a great controversy regarding the possibility of induction of any significant physiological effects in humans by microwave radiations emitted by mobile phones. This study aims to investigate the effects of e...

OBJECTIVE To examine the basal thyroid function in pediatric Obsessive Compulsive Disorder (OCD) versus controls, and to explore the relation between baseline thyroid measures and response to clomipramine treatment, and the effects of treatment on thyroid hormones. METHODS Sixteen children and adolescents with DSM-III-R OCE and 13 control children and adolescents without psychiatric illness w...

The long-held concept of a proportional negative feedback control between the thyroid and pituitary glands requires reconsideration in the light of more recent studies. Homeostatic equilibria depend on dynamic inter-relationships between thyroid hormones and pituitary thyrotropin (TSH). They display a high degree of individuality, thyroid-state-related hierarchy, and adaptive conditionality. Mo...

Thyroid abnormalities have been reported in persons with HIV infection, although data have been inconsistent with respect to its frequency and association with specific medications. The purpose of this study was to explore thyroid system response to thyroid releasing hormone stimulation in persons with and without HIV infection and determine the extent to which their response was associated wit...
