Introduction: The European Registries for Rare Endocrine Conditions (EuRRECa) project aims to support the needs of the endocrine and bone community by facilitating the collaboration between patients, health care professionals and researchers across Europe and beyond. It is a project funded by the European Union’s health programme and is the affiliated registry of the European Reference Network for Rare Endocrine Conditions (Endo-ERN). It consists of two r...

Introduction: The survival rates for childhood cancer have significantly increased over the past decades but the management of treatment-related complications remains challenging. Thus, the introduction of novel drugs requires careful investigation of potential off-target side effects. The developing skeleton is severely affected by the anticancer treatment which may result in growth retardation and short stature. Venetoclax is a selective Bcl-2 inhibitor whic...

Background: Poor growth and under-nutrition are common in children with sickle cell disease (SCD). This review summarizes evidence of impaired linear growth and weight gain in children with SCD in different regions of the world in the past 25 years.Methods: A literature search was conducted on Medline/PUBMED, Google scholar, and SCOPUS, for studies published in English during the past 25 years, using the keywords sickle ...

Background: Growth patterns in infancy and early childhood have been linked to risks of obesity and cardiometabolic disorders in adulthood. Body fat partitioning, particularly increased fat accumulation at ectopic sites, has been strongly associated with cardiometabolic disorders. However, the lack of precise body composition measures in prior longitudinal birth-cohort studies has made it difficult to ascertain if early growth patterns could result in consolidation of distinct...

Background: The actual Swedish growth references are based on a cohort born 1974.Objective and hypotheses: Due to secular changes there is need for new height references.Method: Material: Height measurements from birth to adult height (AH) in a cohort of healthy, Nordic and born full term 1990, 20.796 from 1647 boys, 19.202 from 1501 girls were used (ALL) and compared to both a subgroup with puberty close to mean (PHV &#17...

Background: A new classification of pseudohypoparathyroidism is available (Thiele et al. 2016, J Endocrinol). The phenotype variability of inactivating PTH/PTHrP Signaling Disorders (iPPSD, former pseudohypoparathyroidism) cases is still very challenging, even for experts. Thus, it is crucial to collect data in a centralized manner for future investigation.Methods: The EuRRECa/EuRR-Bone registries are the first ...

Background: The CYP27B1 gene encodes 25-hydroxyvitamin D-1α-hydroxylase. Mutations of this gene cause a rare autosomal recessive disorder, vitamin D-dependent rickets type 1A.Objective and hypotheses: To investigate CYP27B1 mutations in children when rickets was associated with normal or high vitamin D levels and low or inappropriately normal calcitriol levels.Method: All coding exons and intron-exon boundari...

Introduction: Cortisol homeostasis dysregulation has been associated to essential hypertension in adults. Higher levels of cortisol have been described in preterm-born individuals, who have also a higher risk of hypertension at younger ages. Several enzymes modulate peripheric cortisol metabolism. The 11b-hydroxysteroid dehydrogenase (11b-HSD) type 2 metabolizes cortisol into cortisone, preventing mineralocorticoid receptors’ activation by cortisol. The i...

Background: Quality of life (QOL) includes physical, psychological and social aspects. Transgender (TG) children undergo problems in school and with family, friends, and social relationships. These adverse effects on physical and psychosocial health can impair their quality of life.Objective and Methods: This study aims to assess health-related quality of life (HRQOL), using the KIDSCREEN-52 questionnaire (Spanish versio...

Background: The large phenotypic spectrum of Disorders of Sex Development are caused by mutations in many different genes, but a large phenotypic spectrum of sexual disturbancies may also be seen with different mutations in the same gene.Objective and hypotheses: To report on one new mutation in the 5 alfa reductase (SRD5A2) gene, and describe the extremes of the phenotypic spectrum of 5 alfa reductase deficiency presented in two patients.<p class="a...
