Abstract: A cross-sectional study of adrenal function was carried out in 48 patients with beta-thalassemia who were receiving hypertransfusion with suboptimal desferoxamine. A low dose adrenocorticotropic hormone (1 microg ACTH) stimulation test was performed using the cut-off criteria of peak cortisol for adrenal sufficiency >18 microg/dl. Adrenal impairment was diagnosed in 22 patients, giving a prevalence of 45.8%. The peak cortisol concentrations in normal and impaired adrenal function groups were 26.22 +/- 2.84 and 14.03 +/- 3.12 microg/dl, respectively, and the mean basal morning cortisol was 8.93 +/- 2.97 and 6.52 +/- 2.45 microg/dl, respectively. There was no significant difference in any clinical characteristic between the patients with impaired adrenal function and those with normal adrenal function.[Abstract] [Full Text] [Related] [New Search]
