Introduction: Survivors of childhood BMT/TBI have increased cardiovascular morbidity and GH deficiency (GHD). We aimed to investigate the relationship between cardiovascular risk and GHD and GHTx in BMT/TBI survivors.Methods: BMT/TBI survivors (n=36) and non-BMT control subjects (n=19) were sub-divided according to GH status assessed by insulin tolerance test: i) survivors with untreated GHD (N=18,11M), ii) survivors on GHTx (N</i...

Introduction: Data on the impact of TBI on the HPAA are limited. This study investigates the HPAA in BMT-survivors and non-BMT controls using overnight serum cortisol profiles and midnight/9am ACTH levels.Subjects (N=35): N=14, child (7), adult (7) controls, N=21 child (7), adult (14) BMT-survivors (TBI dose 12.0-14.4Gy). None had had treatment with corticosteroids in the last year.Method: Subjects rested for 3...

Introduction: Growth hormone deficiency (GHD) after cranial irradiation (CRI) is time, dose and fraction dependent. TBI (12–14.4Gy) involves low dose CRI, and skeletal irradiation causing further adverse growth effects. We present baseline data from a prospective study of GH treatment.Subjects N=25: We studied 13 BMT survivors (all had TBI, 3 also had CRI <18Gy), and 12 non-BMT subjects investigated for GHD. Both groups contained y...
