Background: Heterozygous mutations in the IGF1 receptor (IGF1R) are often associated with congenital IGF1 resistance, causing variable degrees of intrauterine growth retardation (IUGR) and postnatal short stature. To date, only one homozygous IGF1R mutation has been reported, in a child presenting with severe growth failure, mild intellectual impairment, microcephaly, dysmorphic features, and cardiac malformations.Objective: We now repo...

Background: Mutations in PROP1 are the most common known genetic cause of congenital multiple pituitary hormone deficiency (MPHD).Objective and hypotheses: Aim of our study was to clinically and genetically characterize a cohort of Lithuanian patients with MPHD.Method: Seventy-six Lithuanian MPHD patients were tested for PROP1 gene by Sanger sequencing. Hormonal investigations, pituitary imaging and GH therapy wer...

Background/objective and hypotheses: Not-brain-related birth body weight (NBBW) relevance to known relationships of birth gestational age (GA) with blood serum IGF binding protein 3 (IB3) was studied in the not-life threatened newborn (NWB).Method: SEX, GA (unit:complete week), postnatal age (PNA; unit:day), birth body weight (BW; unit:g), birth head circumference (HC; unit:cm), BW<10th centile for GA (SGA), caesarean section (CS), predominant oral/e...

Background/objective and hypotheses: Parenteral nutrition (KIVD) relevance to known birth gestational age (GA) relations to the blood serum IG2/blood serum IGF binding protein 3 (IB3) ratio (IG2 through chronologically corresponding IB3, IG2/IB3) was studied in the not-life-threatened newborn (NWB).Method: SEX, GA (unit, complete week), postnatal age (PNA; unit, day), birth body weight (BW; unit, g), birth head circumference (HC; unit, cm), GA≤36 (...

Background/objective and hypotheses: Chest circumference (CC) is related to intrauterine growth rate as well as to development-function of respiratory system. We evaluated the relevance of birth body weight (BW) in birth CC (BC) relations to blood serum IGF1 after control for preterm birth (PTB), oxygen (O2) supplementation as %O2 in respiratory gases (O2R) and assisted ventilation of any kind (AV) in the newborn (NWB) without life-threatening ...

Background/objective and hypotheses: Chest circumference (CC) is related to intrauterine growth rate as well as to development-function of respiratory system. We evaluated the relevance of birth body weight (BW) and blood serum IGF1 (IG1) in birth CC (BC) relations to blood serum IGF-binding-protein-3 (IB3) after control for preterm birth (PTB), oxigen (O2) supplementation as %O2 in respiratory gases (O2R) and assisted ventilation of any kind (...

Background: Routine biochemical assessment in patients with congenital adrenal hyperplasia (CAH) includes measurement of serum 17 hydroxyprogesterone (17OHP), androstenedione (A4) and testosterone (T) and their metabolites in urine. Several studies have also described 11 oxygenated 19 carbon (11oxC19) steroids as a clinically relevant androgenetic source and highlighted their potential as markers for evaluation of adrenal androgen excess in patients with 21-hy...

Background: ROHHAD (rapid-onset obesity with hypoventilation, hypothalamic dysfunction, autonomic dysregulation) syndrome is a rare and underdiagnosed disease with high mortality rate. When a neural crest tumor (NET) is detected (56% of patients) the acronym used is ROHHADNET.Aim: To analyze the relationship between clinical variables, hypothalamic-pituitary disorders, DXA parameters and neural tumors, in ROHHADNET patie...

Bile acids (BA) are C24 steroids synthesized from cholesterol in liver. Originally, they were mainly considered to function as emulsifiers supporting resorption of lipophilic food compounds and excretion of metabolic products. Recently, their additional biological and endocrine functions in the regulation of metabolism have aroused interest of researchers. In contrast to BA in blood, it is surprising that hardly any data exist on BA in the most accessible human biof...

Preliminary results:Objective: Although low birthweight (bw) and unfavourable intrauterine conditions have been associated with metabolic sequelae in later life, little is known about their impact on steroid metabolism. We studied genetically identical twins with intra-twin bw-differences from birth to adolescence to analyse the long-term impact of bw on steroid metabolism.Methods:...
