The clinical and biochemical spectrum of pituitary lesions in children compared to adults: experience from a single tertiary center

Galazzi Elena , Carrara Silvia , Soranna Davide , Zambon Antonella , Maria Fatti Letizia , Moro Mirella , Persani Luca ,

We present a monocentric cross-sectional study of 55 children referred between 2000 and 2020 for pituitary lesions, who underwent a complete pituitary function assessment. These data were compared to results obtained in a group of 295 adults carrying pituitary lesions undergoing a complete pituitary screening. Follow-up data was available for 50 children and 248 adults. The mean age at diagnosis in children was 12.2±3.7 years (range 2.1-17.9), while in adults was 48.7&#17...

Optic tract glioma and endocrine disorders- comparison between patients with and without NF1- a single center experience

Gil Margolis Merav , Yackobovitz-Gavan Michal , Toledano Hellen , Phillip Moshe , Shalitin Shlomit ,

Background and Aims: Optic pathway gliomas (OPGs) represent 2-5% of brain tumors in children. OPGs are classified by the anatomic location and whether they are associated with neurofibromatosis type 1 (NF1). Children with OPGs face sequelae related to tumor location and treatment modalities, including visual dysfunction, neurologic deficits, and endocrine dysfunction. The aim of our study was to assess the prevalence of endocrine dysfunctions in patients with ...

Gonadotropin-releasing hormone analog treatment in children with idiopathic central precocious puberty: a pharmacovigilance study in a pediatric population.

Nasso Chiara , Cafarella Giulia , Visalli Giulia , Di Prima Elena , Squadrito Violetta , Squadrito Francesco , Altavilla Domenica , Aversa Tommaso , Wasniewska Malgorzata , Valenzise Mariella ,

Background: Central precocious puberty (CPP) results from premature activation of hypothalamic-pituitary-gonadal axis, which leads to an increased release of gonadotropin-releasing hormone (GnRH). GnRH stimulates the development of secondary sexual features, rapid bone maturation and growth. GnRH agonists (GnRHa) represent the gold-standard therapy in CPP children and their use is responsible for pituitary GnRH receptors down-regulation, luteinizing hormone (L...

Introduction: The activation of the GnRH pulse generator before the age of 8 years in girls and 9 years in boys results in central precocious puberty (CPP). The majority of cases of CPP in girls are defined as idiopathic since no organic lesion is found, whereas intracranial lesions are common in boys with CPP. Previous studies have shown that the height of the pituitary gland in the CPP cases is higher than in the normal children. We aimed to evaluate the pit...

Gonadotropin Flare with Different Depot GnRH Agonists: Comparative Analysis.

Freire Analia , Arcari Andrea , Gabriela Ballerini Maria , Ignacio Bergada , Gabriela Ropelato Maria , Gryngarten Mirta ,

Central precocious puberty (CPP) is effectively treated by inhibition of GnRH signaling through GnRH receptor desensitization with depot GnRH agonists (dGnRHa), but the first injection is associated with a surge in LH and FSH (flare) that proportionally increases estradiol levels. When estradiol levels drop, usually within a fortnight, vaginal bleeding may be seen in a small number of girls. Although dGnRHa that use higher, longer-acting doses are increasingly being used in gi...

Introduction: Achieving/maintaining effective hormone suppression is fundamental in treating Central Precocious Puberty(CPP). CPP patients are vulnerable to late dosing as they cannot self-administer and require clinic/hospital visits for injections, currently exacerbated by COVID-19. In children, the hypothalamic-pituitary-gonadal axis may rebound faster than elderly oncology patients, so hormone escapes are possible with late dosing. Additionally, the stimul...
