Pituitary release of growth hormone and prolactin in the primary fibromyalgia syndrome.

Abstract

Our findings indicate that fibromyalgia, along with ACTH hyperreactivity, also exhibits a distinct disturbance in the GH-somatomedin C axis. With regard to PRL, the variation in individual responses limits conclusions. The hyperreactive response patterns of GH and ACTH previously suggest a common origin, which might be related to a subtle glucocorticoid deficiency.
