Background: The importance of vitamin D for skeletal health is well established and many recent reports indicate that vitamin D deficiency is linked to chronic diseases. Vitamin D status is defined by serum 25-hydroxyvitamin D (25(OH)D), and although there is no consensus on optimal levels of 25(OH)D concentrations of 50 nmol/l (20 ng/ml) meet the requirements in 97.5% of the population. In Sweden, sun cannot synthesize vitamin D during the winter, therefore supplementation is...

Background: Thalassemia major is a hemoglobin disorder characterized by regular transfusion requirement. Despite the regular transfusions and advanced iron chelation protocols, endocrine complications have been reported as the frequent morbidities of the disease.Objective and hypotheses: The aim of the study was to i) investigate the prevalence of endocrine complications, ii) to examine the relationship between endocrine complications and metabolic param...

Background: In recent years, vitamin D is attracting increasing interest due to the resurgence of vitamin D deficiency and rickets in developed countries, identifying their extraesqueletics actions and greater understanding of its many benefits. Vitamin D deficiency in children prevalence of vitamin D deficiency in certain regions described up to 80%, especially at high latitudes (above 37) and some breeds.Objective and hypotheses: To study the degree of...

Introduction: No consensus on vitamin D (VitD) deficiency screening in children and adolescents exists.Aim: To evaluate a sample of patients in whom VitD dosing was performed and determine the rationale for this assessment.Methods: Retrospective, longitudinal study of pediatric patients, from a Portuguese tertiary hospital, who had at least two 25(OH)D level blood sampling between ...

Background: Vitamin D supplementation is widely recommended to infants, but the optimal dose remains unclear. Vitamin D regulates calcium metabolism, and overdosing and high intake may result in hypercalcemia.Objective and hypotheses: We measured serum pH-adjusted ionized calcium (Ca-ion/pH 7.40) concentrations at 6 and 12 months and 25-hydroxyvitamin D (S-25-OHD) at 12 months in order to evaluate the risk of hypercalcemia during vitamin D3 su...

Objective: to study the features of the adipocytokine status and vitamin D status in large for gestational age (LGA) newborns.Materials and Methods: 348 full-term newborns were examined. Three groups of LGA newborns were identified: taking into account the presence of mother’s type 1 diabetes mellitus (DM) (Gr1, n=58, body weight (BW) – 4225 [4000; 4580] g), excess BW or obesity (Gr3, n=65, ...

Introduction: Vitamin D-dependent rickets type 2A (VDDR2A) is a rare autosomal recessive disease that caused by mutations in the vitamin D receptor (VDR) gene. Hypocalcemia, high alkaline phosphatase, secondary hyperparathyroidism, high 1.25-OH vitamin D (1.25-OHD) levels despite normal 25-OH vitamin D (25-OHD) levels are diagnostic. The clinical signs are rickets, short stature, recurrent lung infections and total/subtotal alopecia. Here, we present a case of...

Transversal study. Patients from 0 to 17 years of age who had undergone an analytical determination of 25OHD during the year 2021 in our hospital were collected. The following were contrasted: 25OHD, PTH, total calcium, age, sex, reason for requesting analysis, time of year and country of origin. 25OHD ranges: normal >30 ng/mL, suboptimal 20-30 ng/mL and deficit <20 ng/mL; and normal PTH: 9-60 pg/mL.Results: 1. Prevalence of vitami...

Background: In diabetic patients vitamin D seems to play a role not only on bone metabolism, but also on many other organs and/or systems, such as lipid profile, cardiovascular system, etc. We decided to evaluate whether the celiac disease antibodies in type 1 diabetic patients have a connection with 25-OH vitamin D status.Materials and Methods: 78 young patients with type 1 diabetes were evaluated with mean age of 14&#1...

Background: There is no agreement on the optimal treatment of children with vitamin D deficiency or insufficiency without obvious signs of rickets.Objective and hypotheses: To compare the efficacy and side effects of two different stoss therapy regimens (10 000 IU/kg and 300 000 IU vitamin D3) in children with vitamin D deficiency or insufficiency without rickets.Method: A total of ...
