Hormone-nuclear receptor interactions in health and disease. Glucocorticoid resistance.
Familial glucocorticoid resistance results from the partial inability of glucocorticoids to exert their effects on their target tissues throughout the organism. The condition is associated with compensatory elevations of circulating ACTH and cortisol, with the former causing excess abnormal secretion of steroids with mineralocorticoid and androgen activity. The manifestations of glucocorticoid resistance vary from asymptomatic to chronic fatigue, to varying degrees of hypertension and/or hypokalaemic alkalosis and hyperandrogenism. The latter can be manifest in women as acne, hirsutism, menstrual irregularity, oligoanovulation and infertility, in men as infertility, and in children as precocious puberty. Different molecular defects of the highly conserved glucocorticoid receptor gene, altering its concentration and functional characteristics, appear to cause the syndrome of familial glucocorticoid resistance. Depending on the molecular defect, this syndrome is transmitted by an autosomal dominant or recessive trait. There are recent suggestions that non-generalized forms of glucocorticoid resistance may exist, resulting in autoimmune-inflammatory phenomena or psychiatric manifestations.
