Twenty patients with fibromyalgia syndrome and 20 patients with rheumatoid arthritis (RA) were assessed as outpatients over a 3 day period with respect to peak and trough levels of plasma cortisol, growth hormone, prolactin, ACTH and thyroid stimulating hormone. Patients with fibromyalgia syndrome had loss of diurnal variation in plasma cortisol (trough levels 347.3 +/- 254.7 vs 232.8 +/- 70.0 nmol/l, p less than 0.001) compared with RA patients. Thirty-five percent (7/20) of patients with fibromyalgia syndrome and only 5 percent (1/20) of those with RA exhibited abnormal dexamethasone suppression tests (p less than 0.001). No differences were noted in the diurnal variation of other hormones tested. Beck Depression Inventory scores were similar in both groups and no patient exhibited clinical evidence of depression. These data suggest alteration in the pituitary hypothalamic axis with respect to cortisol secretion in fibromyalgia syndrome, perhaps as a consequence of chronic pain.

Our objectives were to investigate thyroid abnormalities and autoimmunity in 120 patients affected by fibromyalgia (FM) and to study their relationships with clinical data and symptoms. Thyroid assessment by means of antithyroglobulin antibodies, antithyroid peroxidase antibodies, free triiodo-thyronine, free thyroxine, and thyroid stimulating hormone analyses was carried out. The clinical parameters "Fibromyalgia Impact Questionnaire", pain, tender points, fatigue, and other symptoms, and the presence of depression or anxiety disorders were evaluated. The basal thyroid hormone levels of FM patients were in the normal range, while 41% of the patients had at least one thyroid antibody. Patients with thyroid autoimmunity showed a higher percentage of dry eyes, burning, or pain with urination, allodynia, blurred vision, and sore throat. Correlations found between thyroid autoimmunity and age or with the presence of depression or anxiety disorders were not significant. However, in the cohort of post-menopausal patients, the frequency of thyroid autoimmunity was higher with respect to pre-menopausal patients. In conclusion, autoimmune thyroiditis is present in an elevated percentage of FM patients, and it has been associated with the presence of typical symptoms of the disease.
