Indications to GH therapy in children with short stature are still a matter of discussion.We compared first-year response to GH therapy in 80 children (62 boys, 18 girls), age 12.7±2.4 years (mean±S.D.) with different disorders of GH secretion. In all the patients nocturnal GH secretion assessed during 3 h after falling asleep was decreased (<10 ng/ml). In 40 children GH deficiency (GHD) was diagnosed on the ground of decreas...

Normal thyroid hormone secretion (or appropriate L-thyroxin substitution) is necessary for the optimal effect GH administration on growing rate. The decrease of free thyroxin (FT4) levels at GH therapy onset was reported in several studies.The aim of our study was to assess the incidence of hypothyroidism (HT) during the initial phase of GH administration in previously euthyroid children with GH deficiency (GHD) and to compare t...

Considering, the pivotal role of DC in formation and development of autoimmunological processes, the investigation of influence of of thyrometabolic status on maturation and function of subtypes of human peripheral blood DC, seems to be reasonable and of particular interest. THE AIM of the present study was a complex analysis of the dendritic cell subsets and fenotypes in patients with chronic thyroiditis (ChT) as well as the patients monitored for differentiated thyroid cance...

A 32-year old Caucasian was admitted with at 14 weeks of gestation with hypotension and weight loss. Family members noted that she appeared ‘tired’ prior to pregnancy. Past medical history included primary hypothyroidism treated with thyroxine (100 μg/day). Her mother had also been hypothyroid. She had a healthy daughter aged 2.5 years who had been born small for gestational age.At about 8 weeks of gestation she started to vomit several ti...

Background: Nocturnal profile of GH secretion is proposed to be a screening diagnostic procedure for GH deficiency (GHD) in short children. Every screening procedure must be characterised by very high sensitivity and good specificity. The data concerning the cut-off level between normal and subnormal nocturnal GH secretion are scarce and non-consistent.The aim of the study was to assess the clinical utility of 2-h nocturnal profile of GH secretion in dia...

Background: Assessment of nocturnal GH secretion is useful tool in diagnosing GH deficiency (GHD) in children. The time period of the evaluation, the number of blood samples, as well as the choice of cut-off value for this examination – are still the matter for discussion.Aim: The aim of the study was to compare the results of 2-h and 6-h assessment of nocturnal GH secretion in children with suspected neurosecretory dysfunction of GH secretion (NSD)...

Fetal undernutrition is at the base of disorders in the differentiation process of pancreatic beta cells. Abnormal insulin activity leads to restriction of fetal growth and to obesity, insulin resistance and diabetes mellitus type 2 (DM2), either in childhood or adulthood. The aim of the study was to assess the incidence of obesity and insulin resistance in prepubertal children, born with body mass too small for their gestational age (SGA).Material and m...

Background, subjects & methods: Dexamethasone increases visfatin synthesis in vitro, but it is not clear, whether it is reflected in the changes of serum levels of this cytokine. We have therefore assessed fasting serum concentrations of visfatin, glucose, insulin and cortisol in 20 subjects (4 males, 5 subjects with type 2 diabetes) age (mean±S.D.) 42.1±17.2 years, BMI 36,7±8.38 kg/m2 before and after 48 hours of administrat...

Background, subjects & methods: Visfatin, also known as pre-B cell colony enhancing factor (PBEF), is a cytokine that is highly expressed in visceral fat, and exerts insulin-mimicking effects in rodents through activation of an insulin receptor, though in a manner distinct from insulin. Visfatin levels do not change in response to acute hyperinsulinaemia in mice, but it is not clear whether this also applies to humans. In order to investigate this we measured serum visfati...

The effectiveness of thyroid remnants ablation with 131I after thyroidectomy for differentiated thyroid carcinoma (DTC) depends mainly on absorbed radiation dose, which is proportional to 131I uptake (Tup) and its effective half-life time (EHL) in the remnants.Aim: Assessment of endogenous TSH level increment effects on EHL of 131I and Tup in thyroid remnants after surgery for DTC.Material: Twenty-o...
