Persistently increased IGF-I levels and excellent auxological response despite low doses of recombinant growth hormone in a GH-deficient patient with a heterozygous variant of the growth hormone receptor (GHR) gene

Laura Nicolosi Maria , Cattoni Alessandro , Maitz Silvia , Marco Santo Di , Biondi Andrea , Molinari Silvia ,

Introduction: Homozygous loss-of-function mutations of the growth hormone receptor (GHR) gene result in GH insensitivity due to a dysfunctional receptor protein. Heterozygous mutations may result in a variable clinical spectrum ranging from normal height to severe short stature. Gain-of-function variants have been reported rarely.Case Report: We hereby report the case of a Russian boy who was referred to our endocrine o...

Serum anti-Müllerian hormone as a marker of ovarian reserve among childhood cancer survivors

Molinari Silvia , Parissone Francesca , Evasi Veronica , Marco Santo Di , Biondi Andrea , Cattoni Alessandro ,

Introduction: Female patients treated with alkylating agents in childhood are at risk for ovarian impairment. We aimed at describing the pattern of residual ovarian function in a cohort of hematological cancer survivors, assessing the relationship between the cumulative dose of alkylating agents administered (expressed as Cyclophosphamide Equivalent Dose - CED) and Anti-Müllerian Hormone (AMH) levels.Methods: Gonada...

Growth patterns in children with Mucopolysaccharidosis type I-Hurler after haematopoietic stem cell transplantation: comparison with untreated patients

Background: Mucopolysaccharidosis I Hurler (MPS-IH is an inborn error of metabolism arising from the defective activity of alpha-L-iduronidase, an enzyme involved in the degradation of glycosaminoglycans (GAGs). As a result, the pathological lysosomal storage of GAGs in several tissues leads to multi-systemic complications, such as hepatosplenomegaly, progressive central nervous system deterioration, skeletal dysplasia and faltering growth, commonly resulting ...

A novel homozygous variant of the leptin receptor (LEPR) gene causing familiar early-onset severe obesity in two siblings

Molinari Silvia , Ceccarini Giovanni , Masera Nicoletta , Spano Alice , Maitz Silvia , Fossati Chiara , Lazzerotti Alessandra , Santini Ferruccio , Cattoni Alessandro ,

Introduction: The leptin-melanocortin pathway is a well-studied pivotal player of body weight regulation and energy homeostasis. Pathogenic mutations of the genes involved in this pathway may result in early-onset severe obesity (ESO).Case Report: We hereby report the case of a 14-year-old girl who was referred to our pediatric outpatient clinic for the evaluation of ESO. Her parents were non-obese first cousins born in Morocco. At the t...
