Calcium supplements and Supplement D Criteria away from Enterally Fed 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, new Institute away from Medicine (IOM) released dieting guidelines getting calcium and you may supplement D consumption for everyone age range. step 1 Although not, no intake advice were made especially for preterm infants, as they have been considered a different people and didn’t match when you look at the advice to possess weight reduction source consumption produced by the fresh IOM. Preterm infants enjoys novel limbs nutrient standards that will not thought becoming like the ones from full-title infant infants. Past statements in america don’t have a lot of its guidance so you’re able to full-name children. 2 , 3 However, The newest Western european Area to possess Pediatric Gastroenterology, Hepatology, and you will Nutrients has recently discussed enteral diet suggestions for preterm kids. cuatro https://datingranking.net/de/indische-datierung/ , 5
Data in utero limbs mineralization prices try restricted. Cadaver education, starting with the newest vintage functions away from Widdowson et al, 6 basically support a call at utero accretion from calcium into the third trimester regarding one hundred so you can 130 milligrams/kg a day, peaking anywhere between thirty two and 36 weeks’ gestation. Phosphorus accretion is roughly half brand new accretion off calcium during pregnancy. Surprisingly, more recent reevaluation ones analysis that with modern body composition procedure eight considering beliefs like those produced by Widdowson mais aussi 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

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.
