The concentration of 5-hydroxyindoleacetic acid (5-HIAA), homovanillic acid (HVA), kallikrein-like enzymes and beta-glucuronidase were quantified in the cerebrospinal fluid (CSF) during spontaneous migraine attacks. Plasma levels of kallikrein-like enzymes and beta-glucuronidase, as well as urinary levels of 5-HIAA as free acid and glucuronides were also measured. Correlation of these biochemical findings with various clinical variables showed that 5-HIAA in the CSF did not correlate with either the time sequences of migraine attacks or with clinical division of migraine into classical and common migraine. CSF 5-HIAA correlated positively with HVA, EEG photostimulation, the triggering of food and the therapeutic effect of the so-called antiserotonin treatment, and negatively with esterase activity. Urinary 5-HIAA showed a significant increase during the early headache stage.

The serotonin metabolite 5-hydroxytryptophol was studied in human cerebrospinal fluid. A minor fraction (approximately 13%) was found in conjugated form from which it was liberated by treatment with sulphatase containing beta-glucuronidase activity. A concentration gradient of 5-hydroxytryptophol concentration was shown on lumbar tapping and the concentration in ventricular CSF was about 2.5 times higher than that in lumbar CSF. 5-Hydroxytryptophol and 5-hydroxyindoleacetic acid concentrations were significantly correlated in healthy, psychotic, and depressed subjects, but not in alcoholics. 5-Hydroxytryptophol concentrations in CSF of psychotic and depressed subjects were not different from those of healthy controls (4.22 pmol/ml +/- 0.15, SEM). In healthy subjects, hereditary factors seemed to have little influence on the CSF level of 5-hydroxytryptophol.
