The diagnosis was confirmed with the Structured Clinical Interview for DSM-IV.

The uric acid levels were similar (control = 4.08 ± 1.27 mg/dL, depression = 3.78 ± 1.00 mg/dL e bipolar disorder =3.86 ± 1.33 mg/dL, p= 0,251). For maniac/hippomaniac and depressive episodes, were observed a tendency to increase in acid uric levels in maniac/hippomaniac episodes (4.43 ± 1.74 mg/dL) and a decrease in depressive episodes (3.70 ± 0.99 mg/dL) when compared to control subjects (4.08 ± 1.27 mg/dL)(p= 0.106). Conclusion: Uric acid levels is not correlated with diagnosis group, but the uric acid level have a tendency to presented increased in manic and/ or mixed episodes and decreased in depression episode, these result observed that levels of uric acid in mood disorders are altered according to the manifestation of symptoms.
