The author’ goal was to document baseline pituitaryadrenal hormonal and related metabolic variables in 16 female patients with burnout. Then, following stress management intervention, to compare the changes with an equal number of untreated control subjects. At monthly intervals for 4 mo, 24-h urine samples were obtained for determination of free cortisol excretion. In addition, fasting blood samples...
Endocrine disturbances, notably diabetes, have been well described as a complication of iron overload due to hereditary hemochromatosis and β-thalassemia. Dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis has also been well documented. The pattern of iron loading in African iron overload with saturated transferrin is similar to that seen in hereditary hemochromatosis. In addition, many...
The most common malignancy in men worldwide is cancer of the prostate. Androgens play a direct role in normal and malignant growth of prostate cells via the androgen receptor (AR). This study analyzed the polymorphic CAG repeat sequence in exon 1 of the AR gene to determine if the number of repeats might be an indicator of prostate cancer risk or aggressive disease. DNA was extracted from blood samples...
Elevated serum concentrations of endothelium-associated adhesion molecules occur in Graves’ disease. However, no data exist in African subjects, among whom the incidence is rising. Therefore, 20 black South Africans with Graves’ hyperthyroidism were evaluated and 10 healthy controls were also studied. Quantitative determinations of soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular...
The prevalence of hyperthyroidism owing to Graves1 disease is increasing among urban black South Africans. Thyroid-associated ophthalmopathy is often observed in this context, but its pathogenesis remains unclear. No close relationship has been noted between antiflavoprotein (Fp) antibodies or thyrotropin receptor antibodies and ocular involvement in black patients. We measured serum antibodies against...
