Background: Rapid BMI increase in early childhood was found to be a contributing factor for impaired final height in boys with Cystic Fibrosis (CF). This may be explained by early adrenarche triggering an accelerated bone maturation resulting in a compromised growth spurt during puberty, comparable to children with SGA. In healthy Dutch boys, adrenarche starts from the age of 9 years with DHEAS ≥ 1 µmol/L. In Dutch girls, the onset of adrenarche is fr...

Background: Adults with CF show a higher rate of osteoporosis compared to healthy adults. Achieving proper bone mass is a process starting in childhood. We aimed to evaluate the prevalence of decreased bone mineral density (BMD), changes during puberty and risk factors for low BMD in children and adolescences with CF in a large Dutch cohort.Patients and methods: A retrospective observational cohort study was performed in...

Introduction: Data on BP in children with classic congenital adrenal hyperplasia (CAH) is inconsistent.Aim: To assess the trend in BP throughout childhood using data from the International CAH registry and compare this to normative data from the American Academy of Paediatrics (AAP).Method: This retrospective multi-centre study included 37 centres from 20 countries. BP data was ana...

Background: The International Congenital Adrenal Hyperplasia (CAH) Registry provides rich longitudinal data from CAH patients with 21 Hydroxylase deficiency. We estimated the average total causal effect of fludrocortisone on blood pressure in patients with CAH by modelling within a causal inference framework.Methods: We constructed a directed acyclic graph (DAG) with domain experts (using Dagitty.net) to establi...

Background: Alterations in blood pressure in treated CAH due to 21 hydroxylase deficiency is contentious, with studies reporting different effects. We used data from young adults entered into the I-CAH registry to assess the change in blood pressure readings recorded within patients over time.Methods: We used longitudinal mixed effects modelling (LMEM) in R to account for repeated measures in two levels within patients a...
