Background: Accumulating evidence suggests that decreased 25-hydroxyvitamin [25(OH)D] concentrations are associated with components of the metabolic syndrome.Objective: The aim of our study was to investigate the effect of vitamin D supplementation on metabolic syndrome parameters in obese children and adolescents.Patients and methods: Two hundred thirty two (n=232) obese children and adolescents aged [mean ±S....

Background: Vitamin D deficiency has been associated with left ventricular geometry and hypertrophy and larger end-systolic diameters and worse left ventricular function in animals and humans.Objective and hypotheses: The aim of this study was to investigate any possible association between vitamin D levels and geometry of left ventricle (LV) in youngsters with type 1 diabetes mellitus (T1DM).Method: 58 youngsters with T1DM with me...

Purpose: The purpose of this study was to assess the values of the mean platelet volume (MPV), a predictor of cardiovascular disease, in paediatric patients with attention deficit hyperactivity disorder (ADHD) and with autism spectrum disorders (ASD), in addition to healthy controls, to determine the risk of cardiovascular disease in these two disorder groups.Material and method: The study included a total of 79 patients aged 3–18 with ADHD (36 pati...

Background: Vitamin D-dependent rickets type 3 (VDDR3) is a rare autosomal dominant inheritance disease, which is caused by the gain-of-function mutation in CYP3A4 (c.902T>C p.Ile301Thr).Case Presentation: We report the case of a 32-month-old boy presented with discomfort of both knee-joints, poor mobility, and gait abnormality when running. Laboratory examinations revealed low concentrations of serum calcium, phospho...

The CYP27B1 gene encodes 25-hydroxyvitamin D-1α-hydroxylase. Mutations of this gene cause vitamin D-dependent rickets type 1A (VDDR-IA, OMIM 264700), which is a rare autosomal recessive disorder. Herein we report five patients with 1α-hydroxylase deficiencies. We studied six patients from three families who diagnosed as 1α-hydroxylase deficiency clinically. All patients had hypocalcemia, hypophosphatemia, hyperphosphatasemia, elevated serum PTH, normal or high v...

Background: A one-month-old girl was referred to our unit for osteogenesis imperfecta (OI). She was the first child of non consanguineous parents. The father had no history of fracture. The mother, 28 years-old, presented with a severe OI, short adult height (140 cm), moderate scoliosis. She had more than 20 limb fractures, no vertebral fracture and bowing limbs without need of surgery. She received Bisphosphonates during 3 years until 12 years of age. Then sh...

Background: Cyclic treatment with bisphosphonates (BP) is now considered a ‘standard care’ for children with osteogenesis imperfecta (OI). Vitamin D is a necessary nutrient for bone health for all children but especially for those with OI. In the literature few studies have considered the relationship between bone mineral density, vitamin D and pubertal stage in children treated with BP for OI.Objective and hypotheses: The purpose of this study...

Introduction: Vitamin D-dependent rickets (VDDR) describes a group of genetic disorders characterized by early-onset rickets that develops due to insufficient concentration of active forms of vitamin-D or unresponsiveness to active vitamin D. The aim of this study was to share the clinical features and long-term outcome of cases followed up in our center with the diagnosis of either VDDR-Type-1 and VDDR-Type-2.Method: Pr...

Objective: The aim of this study was to analyse bone mineral status in children with epilepsy, on antiepileptic drugs (AEDs) regimen, using serum calcium, 25 (OH) vitamin D and Bone alkaline phosphatase (BALP) and compare these with age and sex matched controls.Patients and Methods: This was a case - control study, conducted at University of Port Harcourt Teaching Hospital, from September 1 2018 to May 31 2019, with 200 ...

Background: Attention Deficit Hyperactivity Disorder (ADHD) is the most prevalent chronic behavioral disorder among children. No definite pathology is yet defined for this disorder and findings are in favor of multifactorial hypothesis.Aims: This study was performed with the aim of determining the association between vitamin D serum levels and ADHD among 6-14 year-old children referring to Imam Khomeini Hospital Complex during 2014–2015 in Tehran, I...
