Summary

Fibromyalgia, a chronic pain and fatigue syndrome, lacks clear biological markers. Current research on stress pathways and hormonal imbalances, including growth hormone, has yielded inconclusive results for understanding its mechanisms.

Area of Science:

  • Neuroscience
  • Endocrinology
  • Rheumatology

Background:

  • Fibromyalgia is characterized by chronic musculoskeletal pain and fatigue.
  • Its underlying biological mechanisms remain largely unknown.
  • Theories suggest chronic stress impacting the hypothalamo-pituitary-adrenal axis and sympathetic nervous system.

Purpose of the Study:

  • To investigate the physiopathological mechanisms of fibromyalgia.
  • To evaluate potential therapeutic approaches based on current understanding.

Main Methods:

  • Review of studies on stress pathways (hypothalamo-pituitary-adrenal axis, sympathetic nervous system).
  • Analysis of hormonal levels, including growth hormone and IGF-1.
  • Evaluation of clinical trial data for growth hormone therapy.

Main Results:

  • Studies on stress mediators yielded scattered and unconvincing results.
  • A reduction in growth hormone and IGF-1 was noted in some patients, but growth hormone therapy produced equivocal outcomes.
  • Other hormonal systems and circadian rhythms appeared largely normal.

Conclusions:

  • Current evidence does not consolidate a specific physiopathological mechanism for fibromyalgia.
  • The role of CRH neuron hyperactivity is suggested but not confirmed.
  • Psychological disturbances may contribute to observed abnormalities, hindering new therapeutic strategies.
