Abstract

Impairment of 25-hydroxylation may be a cause of rickets in infants of low birthweight, weighing between 2000 and 2500 g. In addition there may be impairment of 1 alpha-hydroxylation in infants weighing less than 2000 g. Our data show that a supplementary dose of vitamin D2 of at least 500 IU daily is a reasonable regimen for infants who weighed between 2000 and 2500 g at birth. However for infants who weighed less than 2000 g with a gestation of under 38 weeks, administration of 1 alpha-OHD3 may be more effective in preventing rickets.

摘要

25-羟化受损可能是出生体重在2000至2500克之间的低体重婴儿患佝偻病的一个原因。此外,出生体重低于2000克的婴儿可能存在1α-羟化受损。我们的数据表明,对于出生时体重在2000至2500克之间的婴儿,每天补充至少500国际单位的维生素D2是一种合理的方案。然而,对于出生体重低于2000克且孕周不足38周的婴儿,给予1α-羟化胆钙化醇在预防佝偻病方面可能更有效。
