Is further evaluation for growth hormone (GH) deficiency necessary in Fibromyalgia patients with low serum insulin-like growth factor (IGF)-I levels?

Journal: Growth Hormone & IGF Research. 2007 Feb 5; [E-publication ahead of print] Authors and affiliation: Yuen KC, Bennett RM, Hryciw CA, Cook MB, Rhoads SA, Cook DM. Department of Endocrinology, Oregon Health and Science University, Portland, Oregon.

PMID: 17289417

Objective: Fibromyalgia (FM) is characterized by diffuse pain, fatigue, and sleep disturbances; symptoms that resemble the adult growth hormone (GH) deficiency syndrome. Many FM patients have low serum GH levels, with a hypothesized aetiology of dysregulated GH/insulin-like growth factor (IGF)-I axis. The aim of this study was to assess the GH reserve in FM patients with low serum IGF-I levels using the GH-releasing hormone (GHRH)-arginine test.

Design: We retrospectively reviewed the GHRH-arginine data of 77 FM patients with low serum IGF-I levels referred to our tertiary unit over a 4-year period.

Results: Of the 77 FM patients, 13 patients (17%) failed the GHRH-arginine test. Further evaluation with pituitary imaging revealed normal pituitary glands (n=7), coincident microadenomas (n=4), empty sella (n=1) and pituitary cyst (n=1), and relevant medical histories such as previous head injury (n=4), Sheehan's syndrome (n=1), and whiplash injury (n=1). In contrast, the remaining 64 patients (83%) that responded to the GHRH-arginine test demonstrated higher peak GH levels compared to age and BMI-matched controls (n=24).

Conclusion: Our data show that a subpopulation of FM patients with low serum IGF-I levels will fail the GHRH-arginine test. We thus recommend that the GH reserve of these patients should be evaluated further, as GH replacement may potentially improve the symptomatology of those with true GH deficiency.

Additionally, the increased GH response rates to GHRH-arginine stimulation in the majority of FM patients with low serum IGF-I levels further supports the hypothesis of a dysregulated GH/IGF-I axis in the pathophysiology of FM.
