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...

Introduction: Effects of selected drugs on the efficacy of (131I) radioiodine therapy were examined.Material and methods: The study involved 200 hyperthyroid patients, treated with radioactive iodine. They were divided into five (5) groups (40 persons in each). In group I – beside 131I, patients were additionally administered antithyroid drugs, in group II – 131I and lithium carbonate, group III – 131<...

Introduction: The influence of demographic and clinical factors on the outcome of 131I therapy in hyperthyroid patients has been examined, based on a retrospective evaluation of results obtained in patients, submitted to 131I treatment. The goal of the study was an analysis of factors, including the age and sex of patients, disease duration time, as well the hormonal status before 131I application, which could have influenced the effects of the...

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...

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...

BackgroundThere is no universal consensus regarding vitamin sufficiency status with values either above 20 ng/ml, or 30 ng/ml being quoted as denoting ’sufficient’ status. We have endeavoured to assess the effects of summer sunshine exposure on vitamin D status from a single GP practice in central Poland.Subjects and methodsWe measured concentrations of vitamin D, parathyroid hormone (PTH), creatini...

Back groundBoth pregnancy and polycystic ovary syndrome (PCOS) constitute insulin-resistant states, while gestational diabetes (GDM) is associated with adverse pregnancy outcomes. Though screening for GDM is typically performed later in pregnancy, some women demonstrate significant insulin resistance (IR) and develop GDM even in 1st trimester. We have endeavoured to compare surrogate IR indices in 1st trimester pregnant women and in...
