Calcium and you can Supplement D Conditions regarding Enterally Provided Preterm Infants
Bone health is a critical concern in managing preterm infants. Key nutrients of importance are calcium, vitamin D, and phosphorus. Although human milk is critical for the health of preterm infants, it is low in these nutrients relative to the needs of the infants during growth. Strategies should be in place to fortify human milk for preterm infants with birth weight <1800 to 2000 g and to ensure adequate mineral intake during hospitalization and after hospital discharge. Biochemical monitoring of very low birth weight infants should be performed during their hospitalization. Vitamin D should be provided at 200 to 400 IU/day both during hospitalization and after discharge from the hospital. Infants with radiologic evidence of rickets should have efforts made to maximize calcium and phosphorus intake by using available commercial products and, if needed, direct supplementation with these minerals.
Last year, the new Institute from Medication (IOM) put out dieting guidelines to own calcium and supplement D consumption for all age groups. step 1 not, no intake guidance have been made especially for preterm babies, while they was indeed considered a different sort of people and you may didn’t match in the advice to own diet resource intakes produced by the newest IOM. Preterm infants has book bones mineral standards that can not thought to get similar to those of full-label newborn infants. Previous comments in the usa have limited their recommendations so you can full-term infants. 2 , 3 However, The fresh Western european Area to have Pediatric Gastroenterology, Hepatology, and you can Nutrients has recently explained enteral nutrition ideas for preterm children. cuatro , 5
Studies on in utero bones mineralization costs are minimal. Cadaver studies, beginning with the brand new vintage functions away from Widdowson ainsi que al, 6 generally assistance an in utero accretion out of calcium supplements during the third trimester away from one hundred so you can 130 mg/kg a-day, peaking between 32 and you will thirty six weeks’ gestation. Phosphorus accretion is roughly half of the fresh new accretion out of calcium supplements throughout pregnancy. Amazingly, new reevaluation of these analysis that with modern system constitution processes seven given values just like those people created by Widdowson mais aussi ottime app per incontri universitГ al. 6
In full-term infants, there is a strong correlation between maternal and infant cord blood 25-hydroxyvitamin D (25-OH-D) concentrations, although the cord blood concentration is less than the maternal concentration. 8 A substantial proportion of pregnant women, especially African American and Hispanic women in the United States and Europe, have 25-OH-D concentrations <20 ng/mL (50 nmol/L), 9 a value set for the basis of the Recommended Dietary Allowance. 1 However, in utero, skeletal mineralization is priin D status, making the clinical significance of 25-OH-D concentrations during pregnancy unclear. 10 , 11
Effects of Preterm Birth to the Nutrient Kcalorie burning
Population-based studies of rickets among preterm infants are lacking; therefore, the frequency is not known or reliably estimated. Approximately 10% to 20% of hospitalized infants with birth weight <1000 g have radiographically defined rickets (metaphyseal changes) despite current nutritional practices. 12 This frequency is much lower than the 50% incidence in this population described before fortification of human milk and the use of preterm high mineral containing formulas were routine. 13 One challenge in identifying the prevalence of rickets is the confusion related to terminology. Rickets is defined by radiographic findings, not by any biochemical findings. Standard radiographic definitions of rickets are used. Poorly defined terms, such as osteopenia or biochemical rickets, are often used in the literature interchangeably with radiographically defined rickets. Rickets is not widely reported in preterm infants with birth weight >1500 g unless there are health issues severely limiting enteral nutrition.
