OBJECTIVE: To assess the effect of treating pulmonary hypertension (PH) in infants younger than 1 year of age with systemic glucocorticoids while using echocardiographic and diagnostic biomarkers as measures of efficacy.
STUDY DESIGN: A retrospective chart review was performed on 17 hospitalized infants younger than 1 year of age at St Louis Children's Hospital who received a 5- to 7-day course of systemic glucocorticoid treatment followed by a 3-week taper with no significant intracardiac shunts from January 1, 2017, to December 31, 2021. Quantitative echocardiographic indices for PH, N-terminal pro b-type natriuretic peptide, and/or b-type natriuretic peptide levels were collected before glucocorticoid treatment, after the glucocorticoid burst, and after the 21-day taper.
RESULTS: Mean (±SD) gestational age was 32.1 (±5.8) weeks, 5 infants were (29%) concomitantly treated with sildenafil, and 8 were male. Twelve were classified as World Health Organization group 3 PH (71%) and 5 as World Health Organization group 1 PH. There were significant improvements 30 days after glucocorticoid initiation in b-type natriuretic peptide levels (P = .008), PCO2 (P = .03), eccentricity index (P = .005), right ventricular ejection time (P = .04), pulmonary artery acceleration time (P = .002), and pulmonary artery acceleration time-to-right ventricular ejection time ratio (P = .02). Tricuspid regurgitation velocity was not able to be assessed. There were no mortalities during the study timeline.
CONCLUSIONS: In our retrospective study, systemic glucocorticoid therapy was well tolerated and appeared to be associated with significant improvement in cardiopulmonary function in infants with PH. Further prospective study in a larger sample is warranted.
