Abstract
Fourty-four patients received two doses of 12.5 mg/kg of hydrocortisone or placebo on the first day of life in attempted therapy for respiratory distress syndrome. Follow-up studies were performed on survivors at 5 years of age in ten steroid-treated and seven placebo-treated respiratory distress syndrome subjects. There were no significant differences in growth, intelligence tests, or neurologic examinations in the patients assessed. Abnormal EEGs are present in both groups. Immunologic tests showed no differences in lymphocyte counts, immunoglobulin levels, diphtheria and tetanus antibody titers, or complement components. Diminished percentages of T lymphocytes were found in steroid patients (53%) compared to control subjects (69%). There were also increased percentages of lymphocytes with C3 receptors in steroid patients (20.1%) compared to control patients (13.8%). Episodes of otitis and/or pneumonia were documented in eight of 11 steroid-treated patients between the ages of 1 and 5 years, compared to two of seven patients in the placebo group in the same time period. It is concluded that large doses of steroids on the first day of life may induce lasting immunologic abnormalities and may predispose to an increased incidence of infections.
