Introduction: CFTR-modulating therapy aims to restore CFTR function. It improves lung function and quality of life in CF patients however, its effects on glucose metabolism are not yet well defined.Methodology: Retrospective and longitudinal study.Inclusion criteria: patients with CF genetic diagnosis ≥10 years old on modulator therapy (ivacaftor + lumacaftor or ivacaftor + teza...

Hyperinsulinism is a common cause of severe and persistent hypoglycaemia during the neonatal period. Eleven genes have been identified that lead to unregulated insulin secretion and hyperinsulinemic hypoglycaemia (HH). Inactivating mutations in UCP2 gene have been described in a very small number of patients with HH. UCP2 protein is an inner mitochondrial carrier protein and its loss of function causes enhanced glucose oxidation and increased intracellular ATP synthes...

Hyperinsulinemic hypoglycaemia (HH) is a common cause of severe and persistent hypoglycaemia during the neonatal period. Risk factors for neonatal transient hyperinsulinism are small-for-gestational age (SGA), perinatal asphyxia and maternal diabetes mellitus. This state of hyperinsulinism in SGA newborns could persist from weeks to years, resulting in an important comorbidity; its pathogenesis remains unknown.Objective: To describe the clinical-genetic ...

Introduction: Continuous-glucose monitoring (CGM) is becoming a useful tool to evaluate glucose profiles in real-life conditions and to detect glucose abnormalities undetected by OGTT in CF patients.Objectives: • Evaluation of OGTT and CGM results longitudinally • Evaluation of BMI z-score and %FEV1 changes in relation to OGTT and CGM results. • Analysis of 6 proposed criteria to classify glucose abnormali...

Introduction: Triple CFTR modulator therapy has been shown to improve lung function and quality of life in patients with at least one F508del mutation in the CFTR gen. However, effects on glucose metabolism are not yet well defined. This paper aims to describe the effects of this treatment on glucose metabolism in CF patients.Methodology: Ambispective study.Inclusion criteria: pati...

Introduction: Diagnosis of growth hormone deficiency (GHD) and idiopathic short stature (ISS) is not straightforward. Nowadays growth hormone (GH) stimulation tests play a key role in the diagnosis but they are controversial due to the lack of normative data, poor reproducibility and poor disease concordance.The magnetic resonance imaging (MRI) is also a tool in the study of patients with short stature. Structural alterations of the hypo...

Background: Heat generation in UCP-1 active cells as present in brown adipose tissue contributes to the regulation of energy homeostasis. Brown adipose tissue is known to be present in neonates and infants and has recently also been demonstrated in children and adults. Interestingly, a transition of white adipocytes into a brown phenotype has been documented in vitro in mouse and human cells, yet the underlying mechanisms are still not resolved. Using transcriptome an...

Introduction: Lysosomal Acid Lipase Deficiency (LAL-D) is a rare and systemic condition, secondary to LIPA gene mutations, responsible for lysosomal accumulation of cholesterol esters and triglycerides. Clinical manifestations are heterogeneous in terms of age of onset, severity and biochemical and radiological findings. Dyslipidemia, hepatomegaly and hepatosteatosis with hypertransaminasemia are the most common features. There is significant evidence of incre...

Background: Secretion of catecholamines by adipose tissue M2 macrophages was recently proposed as a molecular mechanism leading to activation of brown adipose tissue and heat generation in mice. However, published data are conflicting and it is not clear whether this pathway might play a role in humans. To shed light on this, we studied macrophage polarization in human white and brown adipose tissue and related it to thermogenic gene expression.Methods: ...

Background: Congenital generalized lipodystrophy (CGL) is characterized by the absence of most adipose tissue at birth due to an adipocyte differentiation block. For several forms of CGL, the underlying mutation and pathophysiological pathway has been identified. However, for many cases the genetic cause is still unknown.Objective and hypotheses: We report a patient with CGL who showed a complete absence of fat apart from protective fat pads in a postnat...
