Fibrositis and primary hypothyroidism.
The prevalence of fibrositis was determined in 100 patients with subclinical or biochemical primary hypothyroidism. Nineteen patients reported symptoms of joint and/or muscle pain with stiffness. Five of these patients presented 7 or more tender points on examination, thus allowing a diagnosis of fibrositis to be made in only 5% of the total group. Symptomatic improvement after thyroid hormone replacement occurred in 10 of the 19 patients, including 3 of those with fibrositis. There were no significant changes in tender points. Our data indicate that fibrositis is uncommon in patients with primary hypothyroidism despite the frequent occurrence of symptoms suggestive of this syndrome.
