Prostaglandin D synthase (PGD synthase) or
beta-trace protein
is a major constituent of human cerebrospinal fluid (CSF) representing-3% of the total CSF protein. We have recently developed a highly specific immunofluorometric assay for PGD synthase, which enabled us to quantify the presence of PGD synthase in fluids and tissues not associated with the CNS. In this report we provide quantitative data of the presence of PGD synthase in CSF and serum from 302 subjects with various neurological diseases and symptoms. PGD synthase levels in CSF are approximately 35-fold higher than those of serum, with a median concentration of 11,299 micrograms/L. A statistically significant association of PGD synthase concentration in CSF was observed with both patient age and gender. There was no correlation between PGD synthase concentration in serum and patient age or gender. To evaluate the clinical utility of PGD synthase in diagnosing neurological diseases, the distribution pattern of PGD synthase in CSF and serum was examined for each neuropathology of 268 patients whose diagnosis was known. No statistical difference was observed between PGD synthase concentration in the CSF (129 cases) or the serum (94 cases) of multiple sclerosis afflicted subjects in comparison to all other patients studied. The distribution pattern was also not different for PGD synthase levels in CSF of patients with HIV/AIDS related neuropathies, viral meningitis and
fibromyalgia
. We conclude that PGD synthase measurement presents no clinical utility in diagnosing neurological disorders in adulthood. PGD synthase may have a physiological and/or pathological role in the developing brain and in neurodegenerative diseases.

It has been observed that acute stress causes the activation of TH1 cells, while TH2 cells regulate and act on chronic inflammation.
Fibromyalgia
(FM) is a chronic, idiopathic disorder which affects about twelve million people in the United States. FM is characterized by chronic widespread pain, fatigue, aching, joint stiffness, depression, cognitive dysfunction and non-restorative sleep. The mechanism of induction of muscle pain and inflammation is not yet clear. In FM there is an increase in reactivity of central neurons with increased sensitivity localized mainly in the CNS. Mast cells are involved in FM by releasing proinflammatory cytokines, chemokines, chemical mediators, and
PGD2
. TNF is a cytokine generated by MCs and its level is higher in FM. The inhibition of pro-inflammatory IL-1 family members and TNF by IL-37 in FM could have a therapeutic effect. Here, we report for the first time the relationship between MCs, inflammatory cytokines and the new anti-inflammatory cytokine IL-37 in FM.
