Background: The most common endocrine cause of growth disorders in childhood is growth hormone deficiency (GHD). The rare monogenic forms of GHD are inherited as autosomal dominant or recessive traits and manifest as isolated deficiency or in combination with other hormone deficiencies. Here, we report on a three-year-old girl with a severe growth retardation (height 77 cm, – 5.6 S.D.S.). She is the only child of non-consanguineous parents from northern Ira...

Background: GH insensitivity is caused by disturbances of GH receptor function or inability to transduce the hormone signal. Affected children are severely growth retarded and may also present immune complications when the transducer STAT5B is defective. Only autosomal-recessive STAT5B mutations have been described to date.Clinical case: Two male 14.5 year monozygotic twins presented with heights of 131.5 cm (−5.3 SDS). Bone age of the ind...

Background: High amounts of protein in meals increase blood glucose in patients with type 1 diabetes. Fat delays the increase of blood glucose. Till now we do not know the amount of insulin necessary to prevent the increase of blood glucose after a fat and protein rich meal (FPRM).Aim: To find the Insulin dosage to normalize glucose level after a FPRM.Patients: Sixteen patients with type 1 diabetes (mean±SD; Age 19.7±2.7 ...

The Silver-Russel syndrome (SRS) is characterized by an intrauterine growth retardation accompanied by postnatal growth deficiency. Affected individuals typically have proportionately short statue, finger deformities as well as typical facial features. About 10% of individuals with SRS have maternal uniparental disomy for chromosome 7 (UPD7) and 35%–50% showed hypomethylation of the parental imprinting center region 1 (ICR1) of chromosome 11p15.5. In the recent past also ...

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: IGF1 and IGF2 are major regulators of somatic growth acting mainly through the IGF1R. Variants in IGF1 and in IGF1R were identified to cause intrauterine and postnatal growth retardation but variants in IGF2 have not yet been reported.Method: In a multigenerational family four affected members (two siblings, one first degree cousin and the daughter of one sibling) exhibited severe growth retardation with heights between −4.2 and −...

Background: It is observed from nearly 50 years that the incidence of diabetes worldwide is increasing. Also the incidence of type 1 diabetes, which is most common in paediatric population, rises across Europe.Objective and hypotheses: The aim of the study was to analyze the incidence of type 1 diabetes in Poland in Pomeranian province in the years 2005, 2010 and 2015. The hypothesis was an increased incidence of type 1 diabetes.Me...

Background: Poland syndrome (PS) is characterized by unilateral absence or hypoplasia of the pectoralis muscle, most frequently involving the sternocostal portion of the pectoralis major muscle, and a variable degree of ipsilateral hand and digit anomalies, including symbrachydactyly. Congenital Hyperinsulinism (CHI) is the result of unregulated insulin secretion from the pancreatic β-cells leading to severe hypoglycaemia. We report a baby with Poland’s syndrome and ...

Background: Hypopituitarism is characterized by deficiency of one or more anterior pituitary hormones. POU1F1 mutations are the second most frequent known cause of combined pituitary hormone deficiency (CPHD). Patients are typically deficient in GH, TSH, and prolactin, although two unrelated cases were reported with isolated GH deficiency (IGHD). To date, all POU1F1 mutations have been reported for the predominantly expressed alpha isoform, which is a transcr...

Objective: IGF-1 receptor mutations (IGF1RM) are a rare abnormality; however, affected patients exhibit severe postnatal growth retardations without catch-up growth. Although several cases of IGF1RM have been described, a comprehensive retrospective analysis of the potential benefit of rhGH treatment is still missing. The aim of this study was therefore to investigate baseline auxology, response to rhGH therapy and potential metabolic effects in patients with IGF1RM in compari...
