Introduction: Paediatric Inflammatory Multisystem Syndrome Temporarily associated with SARS-CoV-2 (PIMS-TS) was first reported by our hospital in the UK. Vitamin D3(25(OH)D) has important roles in cardiac function, immunomodulation, and inflammation. It therefore may be an important biomarker for severity in PIMS-TS, however 25(OH)D status and treatment guidance in PIMS-TS are lacking. We report serum 25(OH)D levels on admission and associations wit...

Background: Vitamin D Dependent Rickets Type IA(VDDR1a) is an autosomal recessive disorder characterized by defects in the biosynthesis of its active form 1,25 dihydroxyvitamin D due to the mutations in the CYP27B1 gene encoding for the enzyme 1α-hydroxylase.Objective and hypotheses: To evaluatethe clinical characteristics, molecular genetics aetiology and long-term outcome of a large nationwide cohort of VDDR-Ia f...

Background: Vitamin D status in children with isolated GHD has been analyzed in few studies with controversial results. The aim of the study was to assess vitamin D status in children with idiopathic GHD in North and Central Greece.Materials and methods: 128 children (M/F: 76/61, mean age 9.5 (S.D.±3.5 years) with isolated GHD were compared with 65 controls (M/F: 46/3, mean age 9.3 (S.D.±3.2 years). Children were d...

Giannios Christos , Farakla Ioanna , Papadopoulos Georgios , Koniari Eleni , Papathanasiou Chrysanthi , Kassari Penio , Charmandari Evangelia

Background: The prevalence of childhood obesity has increased dramatically in the last decades and accounts for a significant increase in morbidity and mortality in adulthood.Objective and hypotheses: To determine the prevalence of 25-hydroxyvitamin D insufficiency and deficiency in overweight and obese children and adolescents.Method: 350 (n=350) children and adolescents (153 males (M), 197 females (F)) were recruited to ...

Vitamin D and male reproduction

Blomberg Jensen Martin ,

Newer studies have indicated that vitamin D has more widespread effects than the classical effects on bone and calcium-phosphate homeostasis. The presence of the vitamin D receptor (VDR) in the testis and male reproductive tract indicates a role for vitamin D in male reproduction. Indeed, vitamin D deficiency and global knock out models of VDR or CYP27B1 in rodents have shown that vitamin D and calcium are important regulators of male reproductive function. Several groups have...

Background: The prevalence of obesity has increased dramatically in Greece in the last decades, and more than 30% of children and adolescents are currently overweight or obese. Obesity is associated with decreased circulating 25-hydroxyvitamin D concentrations, which might predispose to metabolic syndrome and cardiovascular morbidity and mortality.Objective and hypotheses: To determine serum 25-hydroxyvitamin D concentrations and their relationship to ca...

Evaluation of Vitamin D Status and Its Correlation with Gonadal Function in Children at Mini-puberty

Kılınc Suna , Atay Enver

Objective: Most recent evidence from conducted in human and animal studies suggests that vitamin D has a potential role in the physiology of reproductive function in both genders. We investigate the role of vitamin D in male and female gonadal function at mini-puberty period with particular emphasis on production of sex steroids and gonadal peptide hormones. Additionaly, this study evaluated serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradio...

Measured Free 25-Hydroxyvitamin D in Healthy Children and Relationship to Total 25-Hydroxyvitamin D, Calculated Free 25-Hydroxyvitamin D and Vitamin D Binding Protein

Bosch i Ara Laura , Lopez-Molina Maria , Santillan Cecilia , Murillo Marta , Valls Aina , Bel Joan

Introduction: Vitamin D deficiency in children is still a global health problem. Measuring free 25-hydroxyvitamin D concentrations could provide a better estimate of the vitamin D status than total 25-hydroxyvitamin D (25(OH)D) levels.Objective: To assess the relationship between measured free vitamin D (m-f25(OH)D) and calculated free 25(OH)D (c-f25(OH)D), total 25(OH)D, intact parathyroid hormone (iPTH) and other markers of phosphocalcic metabolism.
