Hipocortisolismo por déficit selectivo de CRH de resolución espontánea: análisis de un caso

Hypocortisolism derived from hypothalamic deficiency of corticotropin releasing hormone is a highly unusual cause of adrenal insufficiency and its pathogenesis is still not fully understood. We report a mildly symptomatic patient having repeated low basal plasma cortisol levels with normal cortisol response to ACTH and lisine-vasopresine; however, she showed a clearly limited response to deep hypoglycemia, while GH reached a normal concomitant response. After 7 years of cortisol replacement the endogenous cortisol returned spontaneously to normality. The rest of pituitary function has been always normal
