Abstract:
PURPOSE: We investigated the effects of hypothyroidism on feeding advancement in very low birth weight infants (VLBW). METHODS: This study was a retrospective case-control study of 14 very low birth weight infants (VLBWIs) diagnosed with hypothyroidism and other 14 infants were recruited as age- and weight-matched controls without hypothyroidism or hypothyroxinemia in Seoul National University Children's Hospital between January 2007 and August 2009. We examined whether these infants gained weight more, achieved full-volume enteral feedings sooner, had fewer episodes of increased pre-gavage residuals, and had fewer days of parenteral nutrition. RESULTS: Until full enteral feeding (120 mL/kg/day) was not statistically significant between the groups. In the hypothyroidism group, during the first 14 days after birth, the volume of feeding was smaller [14.7 (0.5-84.0) mL/kg/day, P=0.041], the episodes of increased pre-gavage residuals were frequently observed [16.7 (0.2-78) times, P=0.036], and the duration of central line was significantly longer [18 (10-50) days, P=0.018]. In hypothyroidism group, mean day at first L-thyroxine supplementation was 24.2+/-10.2 days after birth. L-thyroxine administration boosted thyroid function for hypothyroidism infants, helped them tolerate a larger amount of enteral feeding [from 89.5 (2.9-160.8) to 146.9 (31.8-178.8) mL/kg/day, P=0.002] and decreased episodes of excessive gastric residuals [from 5.5 (0-41.6) to 0 (0-44) time, P=0.026]. However, no more weight gain was statistically found. CONCLUSION: In VLBW infants, hypothyroidism may induce feeding intolerance. L-thyroxine supplementation was effective in feeding advancement on preterm infants with hypothyroidism.
