- Abstract
- Background: Transient tachypnea of the newborn (TTN) is a benign disorder with a variable clinical course that often leads to hospitalization. The aim of this study was to assess and validate the relationship between the serum cystatin C level and symptom duration in infants with TTN. Methods: Forty newborns presenting with TTN and who had undergone serum cystatin C (Cys C) tests on the first day of admission to the Kyung Hee University Hospital (Seoul, Korea) from 2009 to 2013 were included. The serum Cys C level, creatinine (Cr) level, estimated glomerular filtration rate (eGFR), and tachypnea duration were correlated retrospectively. Results: The median gestation period was 37.8 +/- 3.8 weeks and the mean birth weight was 3.2 +/- 0.4 kg. Tachypnea duration was 3.3 +/- 2.0 days. Serum Cys C and Cr levels were 1.7 +/- 0.2 mg/L and 0.8 +/- 1.2 mg/dL, respectively. Tachypnea duration was significantly positively correlated with the serum levels of Cys C and significantly negatively correlated with Cys C-based eGFR (p = 0.016), but was not significantly correlated with the serum Cr level or Cr-based eGFR. When tachypnea duration was compared between infants with Cys C level <1.6 mg/L (n = 15; Group A) and infants with Cys C level >= 1.6 mg/L (n = 25; Group B), the symptom duration was significantly shorter in Group A infants (p = 0.011). Conclusion: Tachypnea duration was shorter with higher Cys C-based eGFR in infants with TTN. Copyright (C) 2015, Taiwan Pediatric Association. Published by Elsevier Taiwan LLC.
