title: Cerebrospinal fluid levels of beta-endorphin in patients with fibromyalgia (fibrositis syndrome).
abstract: Cerebrospinal fluid (CSF) samples from 18 female patients with fibromyalgia (fibrositis syndrome) were analyzed for beta-endorphin. The mean CSF level of beta-endorphin was 20.7 +/- 0.7 fmol/ml in the patients compared to 20.5 +/- 2.0 fmol/ml (mean +/- SEM) in healthy controls (p greater than 0.05). Thus, patients with fibromyalgia (fibrositis syndrome) seem to have normal CSF levels of the pain modulatory neuropeptide beta-endorphin.
