Background: Congenital GH deficiency (GHD) can be isolated (IGHD) or combined with other pituitary hormone deficiencies (CPHD). The identification of mutations has clinical implications for the management of patients and genetic counseling1.Objective: To prospectively conduct a molecular-genetic analysis in genes associated with IGHD or CPHD.Method: Forty patients with IGHD (n=8) or CPHD (n=32) were stu...

Background: The aetiology of congenital hypopituitarism (CH) is unknown in the majority of patients. In our cohort of 200 cases, it was possible to establish the genetic cause in only 13 patients (6.5%). Copy number variants (CNVs) have been implicated as the cause of genetic syndromes with previously unknown aetiology.Objective: To study the presence of CNVs and its relevance in patients with CH of unknown cause associated with complex phenotypes.<p...

Background: Obesity is a worldwide epidemic affecting adults and children. Social changes throughout history have contributed to modifications in nutrition and physical activity levels. These changes in lifestyle affected health, increasing the number of metabolic and cardiovascular diseases. Obese children already have a low grade systemic inflammation as well as markers of increased cardiovascular risk. The endothelial function is an important and early marker of atheroscler...

Background: Human IGF1 gene defects are characterized by intrauterine and postnatal growth retardation, sensorineural deafness, microcephaly and intellectual disability. Seven cases have been reported so far, and the underlying pathophysiology has been characterized in only three.Objective: To describe a patient with severe short stature presenting a novel homozygous IGF1 gene mutation and its underlying pathogenic mechanism.<p clas...

TSH/fT4 Ratio as a Marker of TSH Resistance in Pseudoparathyroidism 1A and Obesity

Alimi Aurelia , Rodrigue Danielle , Linglart Agnes , De Filippo Gianpaolo

Introduction: Gsα is imprinted in human thyroid glands and this appears to be important in the development of moderate TSH resistance in pseudohypoparathyroidism (PHP) 1A and less severe TSH resistance in some, but not all, other forms of PHP. Obesity is a clinical condition in which subclinical alterations of thyroid function have been reported, although the relationship between thyroid status and obesity remains unclear. It is uncertain if this biochemical abnormality m...

Background: α-klotho is a transmembrane protein which can be cleaved and act as a circulating hormone. Since low α-klotho levels were found in organic GH deficiency (GHD) and high levels in acromegaly, an interaction between α-klotho, GH and linear growth has been suggested.Objective and hypotheses: We investigated the role of α-klotho protein as a reliable marker of GH secretion in short children and the factors influencing its secre...

Background: Adrenal insufficiency (AI) is a rare condition caused by an inadequate production of glucocorticoids. Preliminary data in adults suggest that AI could be associated with an increased susceptibility to infections; moreover, AI patients are at risk to develop a severe course of infectious diseases and to experience a life-threatening adrenal crisis. The aim of our study is to evaluate the severity and the outcome of COVID-19 in pediatric AI patients ...

The molecular study of Ras/MAPK pathway and treatment of short stature in Noonan syndrome

Castro-Feijóo Lidia , Cabanas Rodríguez Paloma , E Heredia Ramírez Claudia , Martínez Isabel , López Abel Bernardo , Eiris Puñal Jesús , Barros Angueira Francisco , Loidi Lourdes , Barreiro Conde Jesús

Mutations in genes of the RAS/MAPK signalling pathway have been shown to cause several syndromes characterized by dysmorphic features, growth retardation, cognitive impairment, heart disease and cutaneous abnormalities. The GHrh treatment has been used to improve growth in children with Noonan syndrome.Material and methods: 201 cases of patients referred with clinical suspicion of S. Noonan and other RASopathies was studied. Analysis of ...

Background: At present few data have clearly showed an increased frequency of idiopathic central precocious puberty (CPP) in females during the COVID-19 pandemic. The role of environmental factors is not fully understood and various hypotheses have been formulated.Aims of the study: To evaluate retrospectively the incidence of newly diagnosed CPP and other pubertal disorders (Premature thelarche, early puberty, fast pube...
