Introduction: Thyroid hemiagenesis (TH) is a rare inborn anomaly occurring if one of the thyroid lobes fails to develop. Due to limited literature data and lack of large-cohort case–control studies, the clinical significance and management with patients in whom TH was diagnosed, are still a matter of debate. The objective of the study was a complex analysis of a large group of patients with TH in comparison to a control group of subjects born with normal, bilobed thyroid ...

Background: Thyroid hemiagenesis (TH) is a rare inborn anomaly, occurring if one of the thyroid lobes fails to develop. Due to mostly asymptomatic course, it is usually detected incidentally, during investigation of concomitant abnormalities of the thyroid function or structure.Case report: A case of Graves’ hyperthyroidism following primary hypothyroidism due to Hashimoto’s thyroiditis (HT), accompanying a TH, is reported. The patient first pr...

Introduction: Thyroid hemiagenesis (TH) is a rare inborn anomaly of unclear importance. The aim of the study is to describe clinical, hormonal and autoimmunological profile of patients with TH.Material and methods: The studied group consisted of 20 subjects (4 men), diagnosed of having TH at the age from 15 to 63. Laboratory tests, including measurement of serum concentration of thyroid-stimulating hormone (TSH), free thyroxine (FT4), free tri...

Amiodarone is frequently used in cardiac patients but has side effects which effects the thyroid due to its high iodine content. The use of radioiodine in AIH with low iodine uptake is controversial. In these patients therapeutic choices for refractory cases include either: surgery, antithyroid drugs, or glucocorticosteriods.What are the treatment choices in elderly patients which can’t be operated on, agranulocytosis is present, or have toxic liver...

Introduction: Thyroid hemiagenesis (TH) is characterised by congenital absence of one thyroid lobe.Aim: To assess possible association between TH and concomitant alterations of other structures derived from pharyngeal apparatus, which might potentially impact calcium-phosphate balance.Materials and methods: Studied group: 20 patients with TH. Control group: 20 subjects with bilobed thyroid, matched for age and gender. Serum concent...

Introduction: Thyroid hemiagenesis (TH) is a rare inborn anomaly presenting as developmental failure of one thyroid lobe. Recent research on the molecular background underlying thyroid dysgenesis have mainly focused on patients with congenital hypothyroidism. In contrast, subjects presenting TH were only sporadically involved. In addition, whether the same factors are responsible for development of TH and other forms of thyroid dysgenesis is still to be elucidated. Recent stud...

Thyroid hemiagenesis (TH) is a rare inborn anomaly presenting as failure of the development of one thyroid lobe. Recent research on the molecular background underlying thyroid dysgenesis have mainly focused on patients with congenital hypothyroidism; in contrast, subjects presenting TH were only sporadically involved. Changes in transcription factor genes, including TTF1, TTF2 and PAX8, which play an important role in thyroid embryogenesis, have been postu...

IntroductionHepcidin, main body iron regulator protein, decreases iron concentration available for erythropoiesis. Oppositely, excessive erythropoiesis in acromegaly patients (increased GH and IGF-1), may inhibit hepcidin production. GH stimulates bone marrow, whereas IGF-1 receptors are expressed in erythrocytes. Exogenous GH administration in healthy subjects reduced hepcidin level. The role of hepcidin in iron metabolism of acromegaly patients has not...

Introduction: Radioiodine therapy (RIT) in patients with Graves’ disease (GD) and orbitopathy (GO) is still controversial, especially in smokers, due to the risk of exacerbation of ophthalmologic symptoms.Aim: To evaluate the effect of RIT in smoking and non-smoking patients with mild GO in a 6-month follow-up.Patients and methods: We examined 26 smoking and 25 non-smoking patients, matched for age and gender, presenting hyper...

IntroductionTwenty-four years after implementing the national salt iodization programme in Poland in 1997, the country is considered as adequate iodine supply. However, most reports do not take into consideration pregnant or lactating females. Additional intake of 150–200 µg KI per day, independently on levothyroxine (LT4) treatment, is a recommended dose for pregnancy and lactation due to Polish endocrinological guidelines. The study aim was t...
