hiyas, i have had all these sources posted to the uric acid page on wikipedia for quite some time now, but for those who don't have access to read source full-text, here are some excerpts:
Serum uric acid levels in multiple sclerosis patients correlate with activity of disease and blood–brain barrier dysfunction
MS patients were found to have significantly lower serum uric acid levels (193.89 ± 49.05 µmol/l; mean value ±SD) in comparison with healthy donors (292.7 ± 58.65 µmol/l; P = 0.000) and OIND (jimmy: "other inflammatory neuro disease") patients (242.7 ± 46.66 µmol/l; P = 0.001). We found that MS patients with relapse had significantly lower serum uric acid levels (161.49 ± 23.61 µmol/l) than MS patients with remission (234.39 ± 41.96 µmol/l; P = 0.000) and more over, MS patients with BBB disruption had significantly lower serum uric acid levels (163.95 ± 26.07 µmol/l) than those with normal BBB (252.48 ± 25.94 µmol/l; P = 0.000). Further, we also found that serum uric acid level independently correlated with disease activity, BBB disruption, and gender. These results indicate that lower uric acid levels in MS patients are associated with relapse and suggest that uric acid might be beneficial in the treatment of MS.

Many patients have hyperuricemia (uric acid > 7.0 mg/dL in men and > 6.5 mg/dL in women) but do not have gout.

The overlap between uric acid levels in those with and without gout is shown in a study in which the lowest level in a gouty subject was 6 mg/dL, while the highest uric acid in a nongouty person was 9.5 mg/dL.
