    Background: This study examined the effect of corticosteroids on the thymic index (TI) and the thymus/weight index (TWI) in infants exposed to antenatal corticosteroids (ACS). Methods: This prospective study was conducted between August 2014 and October 2018. A thymus ultrasound was performed to assess thymus size on the second day of life. Thymus size was assessed as TI and TWI. Results: In total, 167 neonates (<= 34 weeks gestation) constituted the study population, including 94 ACSexposed infants and 73 untreated infants. The treatment group exhibited significantly lower birth weight and significantly shorter birth length than the ACS (-) group. Therefore, TI was smaller in the treatment group than in the untreated group (6.96 +/- 4.05 cm(3) vs. 5.64 +/- 3.39 cm(3)). The TWI was 3.69 +/- 1.8 cm(3)/kg in the ACS (-) group versus 3.32 +/- 1.56 cm(3)/kg in the ACS (+) group. The median anteroposterior diameter of the right lobe was 1.33 cm (range, 0.45-2.40) in the ACS (-) group compared to 1.15 cm (range, 0.47-2.40) in the ACS (+) group. The median anteroposterior diameter of the left lobe was 1.40 cm (range, 0.43-2.20) in the ACS (-) group and 1.19 cm (range, 0.32-2.36) in the ACS (+) group. The median largest sagittal area was 2.64 cm(2) (range, 0.5-5.46) in the ACS (-) group versus 2.20 cm(2) (range, 0.55-5.90) in the ACS (+) group. Conclusion: We found that TWI was not significantly changed by ACS exposure in premature infants. (C) 2021 French Society of Pediatrics. Published by Elsevier Masson SAS. All rights reserved.
