Decreased serum levels of insulin-like growth factor I (IGF-I) are common in patients with fibromyalgia, which is frequently associated with chronic fatigue syndrome (CFS). Twenty patients with CFS (7 men, 13 women; age range, 30-60 years) and age- and sex-matched controls were tested for peak GH responses to insulin-induced hypoglycaemia and arginine administration. Nocturnal secretion of GH and serum levels of IGF-I were also measured. Serum IGF-I SDS (+/- SD) was significantly lower in patients with CFS than in controls (SDS, -0.39 +/- 1.07 vs 0.33 +/- 0.84; P = 0.02). Patients with CFS also tended to have reduced nocturnal secretion of GH (area under the curve, 32.4 +/- 18.3 vs 62.7 +/- 43.7 microg/l/15 minutes; P= 0.06), but peak GH responses to insulin-induced hypoglycaemia and arginine administration did not differ significantly between the two groups. It is not clear whether the tendency for impaired spontaneous nocturnal GH secretion in patients with CFS is a cause or an effect of the condition.

Reportedly, fibromyalgia (FM) is frequently associated with reduced IGF-1 levels and GH hyporesponsiveness to different GH stimulation tests. Since there is a high prevalence of obesity in FM, and obesity itself is characterized by hyposomatotropism, the aim of this study was to assess IGF-1 levels and GH responsiveness in sixteen severely obese women suffering from FM, who, subdivided into two subgroups on the basis of their age-dependent IGF-1 values (> or <-2 SDS), underwent the combined GHRH plus arginine test. Four out of 16 obese women with FM (25%) had low IGF-1 SDS values, 2 cases of this subgroup (12.5%) failing also to normally respond to the test. Among patients with normal GH responses, 4 showed a delayed GH peak. The subgroup with low IGF-1 SDS values had higher BMI than that with normal IGF-1 SDS. GH peak and area under the curve were not correlated with CRP, ESR, or tender point score, while significant correlations were found with fat-free mass and fat mass. In conclusion, this study shows the existence of a high prevalence of GH-IGF-1 dysfunction in patients with both FM and obesity, presumably as a consequence of the obese rather than fibromyalgic condition.
