Longitudinal study of adrenocortical function following allogeneic bone marrow transplantation in children.
Basal serum concentrations of cortisol, dehydroepiandrosterone (DHA) and its sulfate (DHAS), 4-androstene-3,17-dione (A4) and 17 alpha-hydroxyprogesterone (17OHP) were measured yearly in children treated with bone marrow transplantation (BMT) with or without preceding total body irradiation (TBI). Age-matched controls were used for comparison. ACTH stimulation tests were performed in the patients before and after treatment. However, in the samples taken before BMT only cortisol was measured. Basal posttreatment cortisol levels were subnormal in TBI-treated boys (n = 14, aged 5-17 years at BMT) during the adrenarcheal period (7-14 years) but became normal afterwards. All other groups had normal cortisol values. Treatment neither affected basal levels nor the ACTH-induced increment (delta-value) of cortisol. In the boys treated with TBI, normal basal levels of 17OHP and adrenal androgens were found with the exception of decreased DHA levels in the postadrenarcheal boys. However, the delta-17OHP values and had an abnormal age relation and were significantly higher than in the patients not treated with TBI. In the patients not treated with TBI (6 boys aged 2-17 years) normal responses were found for 5 years or more after treatment. In female patients treated with TBI (n = 12, aged 1-16 years) circulating levels of DHA, DHAS and A4 were significantly decreased up to 5 years or more following treatment. It is concluded that after TBI, the cortisol homeostasis is maintained at the cost of reduced adrenal androgen secretion.
