- Abstract: PURPOSE: 17-Hydroxyprogesterone (17-OHP) screening results are difficult to interpret owing to the many influencing factors, and confirming the test results takes time. In this study, we examined the factors that affected the 17-OHP level in premature infants. We also evaluated the correlation between 17-OHP level and the clinical parameters related to adrenal cortical function. METHODS: From January 2012 to April 2017, 358 very-low-birth-weight infants (VLBWI) born with birth weights of < 1,500 g were included in the study. Their 17-OHP levels were measured in the neonatal screening test after birth and analyzed by considering various factors that may have influenced the values. RESULTS: The 17-OHP levels negatively correlated with gestational age and birth weight. The values of the parameters that affected the 17-OHP levels were significantly higher in the infants with respiratory distress syndrome (RDS). In relation to the clinical parameters, blood pressure measured within 24 hours, 72 hours, and 1 week after birth negatively correlated with the 17-OHP level. Serum sodium and 17-OHP levels 24 hours after birth were found to be positively correlated. Urine outputs in 1 and 3 days after birth showed significant positive correlations with the 17-OHP level. CONCLUSION: The 17-OHP levels of the VLBWIs were higher when gestational age and birth weight were lower, and were influenced by RDS in the VLBWI. In addition, hypotension and urine output values may be useful in the neonatal intensive care unit as a predictor of early adrenal insufficiency.
