IGFBP-3 assessment in the work-up of short stature

DeodatiAnnalisa , Inzaghi Elena , Elisa Amodeo Maria , Cianfarani Stefano

Background: The diagnosis of GH deficiency (GHD) is not straightforward in childhood and adolescence, requiring comprehensive clinical, anthropometric, biochemical, endocrine, and neuroradiological assessment. Although pharmacological GH stimulation tests are still considered the gold standard for GHD diagnosis, they are burdened by both poor specificity and side effects. Several studies have addressed the issue of sensitivity and specificity of IGFBP-3 assess...

rhGH therapy in a patient with homozygous IGF1R mutation

Elisa Amodeo Maria , Deodati Annalisa , Mirra Giulia , Tattesi Giulia , Cianfarani Stefano

Background: IGFR1 gene plays a crucial role in growth and glucose metabolism. IGF1R mutations account for approximately 10% of children born SGA with no catch-up growth. rhGH therapy has been reported moderately effective in stimulating growth of children with heterozygous IGF1R mutation. To date, no data are available about the efficacy of rhGH in patients with homozygous mutations.Case report: We describe a 4 years-old...

A real life evaluation of rhGH efficacy in children born SGA

Tattesi Giulia , Deodati Annalisa , Inzaghi Elena , Elisa Amodeo Maria , Bizzarri Carla , Cappa Marco , Cianfarani Stefano

Background: Children born SGA are at risk of becoming short adults. Although most children born SGA show catch-up growth in the first 24 months of life, approximately 10% remain below the 3rd centile throughout childhood and adolescence. The available evidence shows that GH therapy can increase adult height in short children born SGA although long-term response is variable and closely related to the 1st year response.Aims:</stron...

A point mutation of SH2B1: a new cause of monogenic obesity?

Early identification of monogenic obesity, a rare condition, is quite challenging for pediatricians. Src-homology-2 (SH2) B adapter protein 1 (SH2B1) is an important component in the leptin-melanocortin pathway and it is found to play an important role in leptin and insulin signaling. In humans a rare deletion of a 220-kb region on chromosome 16p11.2 encompassing approximately 9 genes, including the SH2B1 gene, is associated with a highly penetrant form of isolated severe earl...

Background: Terminal or interstitial deletions of Xp (Xp22.2→Xpter) in males have been recognized as a cause of contiguous gene syndromes showing variable association of apparently unrelated clinical manifestations such as Leri-Weill dyschondrosteosis (SHOX), chondrodysplasia punctata (ARSE), mental retardation (NLGN4), ichthyosis (STS), Kallmann syndrome (KAL1), and ocular albinism (GPR143).Case reports: We report ...

Familial Central Precocious Puberty: a case of three siblings with MKRN3 mutation

d'Aniello Francesco , Ubertini Graziamaria , Elisa Amodeo Maria , Mirra Giulia , Criscuolo Sabrina , Mucciolo Mafalda , Fintini Danilo , Cappa Marco

Introduction: We report a series of three siblings, two girls and one boy, diagnosed with Central Precocious Puberty (CPP) respectively at the age of 5.66, 6.67 and 8.5 years, carrying a mutation in the gene encoding the makorin RING finger protein 3 (MKRN3), usually responsible for the development of familial CPP.Methods: We diagnosed CPP in all the patients by performing a GnRH test. We also dosed basal levels of LH, F...

Endocrine Late Effects In Survival Children With High-Risk Neuroblastoma From Italian Tertiary Hospital

Background: The treatment of high-risk neuroblastoma still represents a clinical challenge in pediatric oncology. About 50% of children survive after a multimodal treatment based on conventional and high dose chemotherapy, surgery, radiotherapy, differentiating treatment and immunotherapy.Aim: To evaluate endocrine long-term sequels in a pediatric cohort with high-risk neuroblastoma.Patient...

A case report of Hirschsprung Disease and C Cell Hyperplasia: a new RET gene variant?

We report and discuss a case of a girl who at birth underwent surgery for Hirschsprung Disease (HD). To closely investigate her condition, we used a Next Generation Sequencing (NGS) panel to carry out a study of some of the genes known as being associated with congenital megacolon (PHOX-2B, RET, EDN3, GDNF, ASCL1 and BDNF). This analysis showed a maternally inherited heterozygous variant in the RET protooncogene (c.734T>A, p.Val245Glu), which is not described in the scienti...

A case of Noonan's syndrome and Combined Pituitary Hormone Deficiency: a new potential association?

Noonan syndrome (NS) is an autosomal dominant, variably expressed, multisystem disorder with an estimated prevalence of 1 in 1000–2500. In 2001, PTPN11 was the first gene associated to Noonan syndrome; now, at least 20 other genes have been discovered especially in the RAS–MAPK signalling pathway. More recently, missense mutations in RIT1 have been reported as causative of NS. A six-years female patient was referred to our Hospital for short stature (<-2 sds) an...
