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...

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:</...

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...

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...

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 ...

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...

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...

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...

Background: Hereditary 1,25-dihydroxyvitamin D resistant rickets (HVDRR) caused by vitamin D defective receptor.Objective and hypotheses: We performed VDR gene analysis four patients with alopecia, skeletal dysplasia, and hypocalcaemia.Method: Genomic DNA extracted from peripheric blood. Whole gene sequence analysis was performed.Results: We found homozigot p.Q152* (c.454G>T) mutation three patients. Two ...
