Pediatric Hypovitaminosis D

Pediatric Hypovitaminosis D

Vitamin D, a secosteroid, is essential for the development and maintenance of healthy bone in both the adult and pediatric populations. Low level of 25-hydroxy vitamin D (25-(OH)-D) is highly prevalent in children worldwide and has been linked to various adverse health outcomes including rickets, osteomalacia, osteomalacic myopathy, sarcopenia, and weakness, growth retardation, hypocalcemia, se...

[Hypovitaminosis D in pediatric patients on renal replacement therapy].

BACKGROUND Hypovitaminosis D has a high prevalence among patients with chronic kidney disease (CKD). AIM To determine the prevalence of 25 hydroxy vitamin D (25(OH) D) insufficiency and deficiency in pediatric patients on dialysis and kidney transplantation. MATERIAL AND METHODS Serum calcium and phosphorus, parathormone (PTH), alkaline phosphatases and 25 (OH)D were measured in 13 children...

Hypovitaminosis D in healthy schoolchildren.

BACKGROUND Vitamin D is essential for skeletal growth, but there are currently no guidelines for vitamin D supplementation after infancy. This study investigates vitamin D insufficiency in healthy children. METHODS Children ages 10 to 16 years from 3 private schools in Beirut, Lebanon, with differing socioeconomic status (SES) were studied: 169 in the spring of 1999 and 177 in the following f...

Pilot Study Evaluating Efficacy of 2 Regimens for Hypovitaminosis D Repletion in Pediatric Inflammatory Bowel Disease.

OBJECTIVES Vitamin D is critical for skeletal health; hypovitaminosis D is common in pediatric inflammatory bowel disease (IBD), yet optimal repletion therapy is not well studied. We aimed to conduct a pilot trial comparing the efficacy of 2 vitamin D regimens of weekly dosing for the repletion of hypovitaminosis D in pediatric IBD. METHODS Subjects identified from our IBD clinic with 25-hydr...
