This study reports an improved approach for the determination of neuropeptide levels in human cerebrospinal fluid (CSF). The method is based on sample acidification followed by liquid-liquid extraction (LLE) combined with radioimmunoassay. It was applied to study the recovery and level of some opioid peptides (Met-enkephalin-Arg(6)-Phe(7) and Leu-enkephalin-Arg(6)), substance P and the substance P(1-7) fragment, which are all compounds known to be present in human CSF. The results indicated that the use of LLE highly improved the recovery of these peptides compared to current liquid-solid-phase extraction methods by using silica gel cartridges or mini-columns for ion-exchange chromatography. Peptides added to CSF in concentrations down to 10 fmol/ml were recovered in yields exceeding 80%. The mean recovery of synthetic peptides as recorded by radioimmunoassay in the LLE procedure was significantly improved when HCl was added to the sample. In contrast, when the (125)I-labeled analogues of the peptides were added to CSF samples, the mean recovery of the four labeled peptides using the LLE procedure was markedly reduced in acidified samples. We also found that the inclusion of HCl effectively improved the removal of proteins present in the samples. As an application the levels of substance P and Met-enkephalin-Arg(6)-Phe(7) in CSF samples from patients with chronic pain (fibromyalgia syndrome) were measured using the new procedure. It was possible to confirm a significant difference in the CSF levels of both peptides when comparing patients and controls.

Two surveys of individuals with fibromyalgia were conducted to assess the frequency and prevalence of symptoms (N = 99) as well as healthcare providers, medications, and self-care activities used to manage one's fibromyalgia (N = 54). The pervasiveness of symptoms was striking, with 24 various symptoms ranging from cognitive to intestinal problems occurring in at least 75% of the respondents. Significant correlations were present between health status and both physical (P = .002) and psychological (P =.008) symptoms. There was also a significant correlation between the total number of symptoms and the degree of life disruption attributed to fibromyalgia (P =.015). A variety of healthcare professionals were seen, with internists, family physicians, and rheumatologist most frequently used. Although at least 80% of the respondents reported difficulty with anxiety, confusion, irritability, depression, and cognitive difficulties, less than 10% of the respondents reported seeing a psychiatrist. Most frequently used medications were: amitriptyline, (fluoxetine HCl) Prozac, ibuprofen (Motrin), sertraline HCI (Zoloft), and zolpidem (Ambein). Self-care activities used with the most success were walking, stretching, and exercising. These studies indicate the need for more research and support for healthcare providers as well as patients with fibromyalgia.
