Background: After 50 years of hGH use for GH deficient (GHD) children the definition of the adequate hGH substitution dose and response remain uncertain.Objective and hypotheses: We hypothesized that subjects with GHD caused by congenital pituitary defects constitute an ideal model for defining substitution dose of hGH. Consequently, an appropriate study group was formed and pertinent long-term data were retrospectively analyzed.Me...

Background: Screening for congenital hypothyroidism (CH) with the possibility of an early treatment has transformed the outlook for children with CH. Despite the unquestioned public health success of newborn screening programs, the management of CH is still controversial. Most patients with positive screening have permanent hypothyroidism but some of them may have transient hyperthyreotropinemia, so it is important to identify these patients in order to avoid lifelong unnecess...

Objective: to evaluate combination replacement therapy (CRT) with rFSH and hCG of hypogonadotropic hypogonadism (HH) in boys appropriateness and effectiveness.Materials: 1 boy with isolated HH (№1) and 2 boys (№2,3) with HH caused by hypopituitarism (HP) included. Antropometric data, Тanner; testosterone (T), LH, FSH, inhibin B, anti-Mullerian hormone (AMH), testicular volumes (TV), bone age (BA) evaluated in all patients. GnRH agonis...

Aim: Central precocious puberty (CPP) is defined as premature activation of the hypothalamic–pituitary–gonadal (HPG) axis before the age 8 in girls. Precocious puberty starting at a very young age causes a severe loss in height potential and should be treated with gonadotropin releasing hormone agonists (GnRHa). However, there are controversial results about the benefit of the GnRHa treatment in girls whose CPP is initiated near the age 8. This stu...

Introduction: Mutations in the thyroid hormone (TH) transporter MCT8 result in MCT8 deficiency, which is characterized by severe intellectual and motor disability and high serum T3 concentrations inducing thyrotoxicity in peripheral tissues. At present, no effective treatment is available, although preclinical studies suggest that the T3 analog Triac is a promising candidate to i) normalize serum T3 levels and thus alleviate the thyrotoxicosis and ii) restore TH signaling in t...

Introduction: Short stature is frequently associated to neurofibromatosis (NF). In these patients this condition is often caused by growth hormone (GH) deficiency. We describe four boys affected by NF type 1 and GH deficiency treated with GH replacement therapy.Case report: GH deficiency was diagnosed in four patients with NF type 1, who were referred to our Pediatric Endocrinology Unit for short stature. Patient 1 started GH replacement therapy at the C...

Background: The risk of cardiovascular diseases is increased in girls with TS. The influence by combined GH and estrogen treatment on a condition of cardiovascular system is actively discussed.Objective and hypotheses: We performed this study to assess th effects of combined GH and estrogen treatment on lipid metabolism and systolic function of the left ventricle (LV) in girls with Turner syndrome without clinically relevant cardiac abnormalities.<p ...

Purpose: The goal of treatment for true precocious puberty (TPP) and early puberty with GnRH agonist (GnRHa) is to prevent loss of genetic potential of target height (TH). And to regress secondary sex characteristics appropriate for patient’s age. But some patient’s growth velocity (GV) after treatment would decline and suggest that final height (FH) was not improved. So, we investigated the effect of combined GH and GnRHa treatment for near-FH (NFH) improvement....

Background: AHDS is a devastating disease caused by defects in the thyroid hormone (TH) transporter MCT8. Endocrine expression is heralded by systemic hyperthyroidism with elevated serum T3, mildly increased TSH and decreased T4. However, the brain is hypothyroid, causing severe psychomotor retardation. Therapeutic attempts with PTU+levothyroxine or the T3-analogue DITPA could normalize TH derangements but without any neurological improvement. ...

Background: SHOX deficiency is a frequent cause of short stature. GH therapy has been approved for growth promotion in individuals with SHOX mutations by FDA and EMEA.Case report: Three patients with Leri-Weill syndrome (LWS) started GH therapy at different chronological ages (CA). Patient 1 started GH+LHRHa at the CA of 13.4 years, height 148.4 cm (−1.5 S.D.), Tanner stage 4, bone age (BA) 13 years. Target height (TH) 160.5 cm (&#87...
