Neonatal Hypocalcemia Due to Maternal Hypovitaminosis D: A Cohort of Children in a Region of Northern Spain

Zuber Maria Laura Bertholt , Martin Concepcion Freijo , Arias Pilar Gortazar , Fernandez Sonia Vilanova , Santos Ana Belen Perez , Amunarriz Maria Garmendia , Revuelta Inmaculada Palenzuela

Background: Neonatal hypocalcemia is defined when the total calcium levels are under 8 mg/dl (Ionic Ca < 1.1 mmol/l) in the full-term newborn, and under 7 mg/dl (Ionic Ca < 1 mmol/l) in the preterm. The fetus entirely depends on the maternal contributions of 25-OH-vitamin D, whose levels are directly correlated with diet and solar exposure. The largest transfer in calcium and vitamin D occurs in the third trimester of gestation, so prematurity is an important risk fact...

Optimal 25-OH-Vitamin D level in children derived from metabolic parameters

Gillis David , Hefter Ari , Edri Edri Shalom , Strich David

Context: Optimal levels of 25-OH-Vitamin D (25OHD) for children are unknown. Prevalent population levels of 25OHD are likely to be sub-optimal since sun exposure is reduced in modern living.Objective: To deduce recommended levels of 25OHD by testing, in children, the level at which 25OHD optimally effects calcium, phosphate and parathyroid hormone levels in a population-based data.Design:</...

Effects of Nutrition and Vitamin D Deficiency on Central Puberty Precocious

Bayraktar Hatice Asli , Kirmizibekmez Heves , Koksal Eda

Background: Puberty is a dynamic period of physical growth. Genetic factors, increasing prevalence of adiposity, environmental factors and the widespread presence of endocrine-disrupting chemicals are suspected to contribute to the trend of earlier pubertal onset.Method: The study group consists of 32 girls diagnosed with central puberty precocious. The eating habits and physical activity status were evaluated with a detailed questionnaire. Daily calorie...

Vitamin D dependent rickets Type 2A: A case series of two siblings with novel mutation in vitamin D receptors responded to high dose oral calcium and calcitriol.

Mehak Noor-ul-ain , Aftab Sommayya , Saddam Hussain Syed , Imran Ahmed , Ali Qureshi Abid , Saeed Anjum , Arshad Cheema Huma

Background: Vitamin D dependent rickets Type 2A (VDDR2A) is a rare autosomal recessive disorder due to mutation in vitamin D receptor (VDR) leading to hypocalcemia, secondary hyperparathyroidism and signs of rickets. It usually presents with bony deformities along with complete or partial alopecia and is challenging to manage.Objective: We are reporting case series of two siblings with VDDR2A who were managed in a non-co...

The Relationship Between Vitamin D Status and Metabolic Abnormalities in Females with Classical Congenital Adrenal Hyperplasia: A Pilot Study

Hassan Mona , Ibrahim Amany , Abdou Marise , Atty Sahar Abdel , Nabil Diana

Congenital adrenal hyperplasia (CAH) patients have a higher frequency of obesity, visceral adiposity, hyperinsulinism, insulin resistance and hyperandrogenism. There is increasing evidence that low vitamin D status is associated with impaired β-cell function, insulin resistance and impaired glucose tolerance.Objectives: This pilot aimed to determine the status of serum 25 (OH) D levels in CAH female patients who are followed up in Diabetes Endocrine...

Effects of Socioeconomic Status on Bone Mineral Density and Vitamin D Concentrations in Healthy Female College Students

Ersoy Betul , Kizilay Deniz Ozalp , Gumuser Gul , Taneli Fatma

Background: Skeletal mass approximately doubles at the end of adolescence. Socioeconomic Status (SES) and Vitamin D status may play a role in the development of bone mass.Objective and hypotheses: The aim of the present study is to examine the effects of different socioeconomic conditions on bone mineral density (BMD) and vitamin D status in healthy female college students and to determine the possible association between Vitamin D status and BMD.<p ...

A Case of Vitamin D Dependent Rickets Type 1 with a Novel Mutation in CYP27B1 (25-OH Vitamin D-1-α-Hydroxylase) Gene

Ozcabi Bahar , Evliyaoglu Olcay , Ercan Oya , Tahmiscioglu Feride , Jaferova Sevinc , Oruc Cigdem , Adrovic Amra

Background: Vitamin D dependent type 1 rickets is a rare, autosomal-dominantly inherited disorder due to an inactivating mutation in CYP27B1 (25-OH vitamin D-1-α-hydroxylase) gene. It is characterized by early onset of rickets with hypocalcemia. We report a boy admitted with symptoms of hypocalcemia and who carried a novel mutation in CYP27B1 gene.Case: The patient was admitted with tetany at the age of 12 months. When he had his first convulsion, h...

The Prevalence of 25-Hydroxyvitamin D Insufficiency and Deficiency Among Overweight and Obese Children and Adolescents in Greece

Giannios Christos , Farakla Ioanna , Papadopoulos Georgios , Bakopoulou Ioanna , Nicolaides Nicolas C , Papathanasiou Chryssanthi , Drakopoulou Maria , Chrousos George P , Charmandari Evangelia

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...

Cord Blood Vitamin D Concentrations in Native and Immigrant Population from a Mediterranean Area in Spain

Guagnelli Miguel Angel , Yeste Diego , Ferrer Roser , Comas Inmaculada , Carrascosa Antonio

Background: Recent studies have found a widespread deficiency of vitamin D during pregnancy. Its significance is still not fully understood, although low Vit-D levels have been associated to increased risk for conditions such as preeclampsia, bacterial vaginosis, neonatal sepsis, and early respiratory infections in the child. Supplementation to the pregnant mother is still a matter of debate, therefore it is important to understand better the causes, risk factors, and possible...
