Vitamin A levels at birth of high risk preterm infants.
Vitamin A levels were measured shortly after birth in preterm infants at high risk of developing chronic lung disease (CLD). Eleven infants, median gestational age 24 weeks, developed CLD. Their results were compared to 11 infants who, although they required mechanical ventilation for at least 48 hours, did not develop CLD. The median gestational age of this latter group was 30 weeks (range 27-35). The median vitamin A level of the infants who developed CLD was 0.62 umol/l (range 0.41-0.95), which was significantly higher than the median level of the infants who did not develop CLD, which was 0.36 umol/l (range 0.13-0.89). We conclude preterm infants who develop CLD are not predisposed to develop that complication by low vitamin A levels at birth.
