Calcium and you may Vitamin D Criteria from Enterally Given Preterm Kids

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 brand new Institute off Treatments (IOM) put out weightloss advice getting calcium and you may supplement D intakes for all age groups. step 1 However, no consumption information were made especially for preterm infants, while they were thought a separate society and you may didn’t match in the advice for dieting source intakes developed by the IOM. Preterm children have book limbs nutrient standards that may not be thought to get like those of complete-label newborn kids. Early in the day statements in the usa have limited their suggestions in order to full-title kids. dos , step three not, The fresh European Neighborhood to own Pediatric Gastroenterology, Hepatology, and you can Nourishment has recently explained enteral nutrition recommendations for preterm kids. cuatro , 5

Data on in utero bone mineralization prices try limited. Cadaver knowledge, beginning with brand new classic performs away from Widdowson et al, 6 fundamentally support an in utero accretion of calcium for the 3rd trimester away from a hundred so you’re able to 130 mg/kg just about every day, peaking anywhere between 32 and you will thirty-six weeks’ gestation. Phosphorus accretion is roughly half the latest accretion from calcium supplements while in the gestation. Remarkably, more recent reevaluation of those data by using modern system constitution process seven https://datingranking.net/de/kunstler-dating-sites/ considering thinking exactly like those created by Widdowson et al. six

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

Negative effects of Preterm Beginning towards the Nutrient Metabolic process

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.
