Introduction It is important to make an early and effective intervention from the first bipolar episode. The presence of depressive symptoms in the course of a manic episode could influence negatively the evolution and the prognosis of the patient. Inflammation and oxidative stress are also related with functionality. Objectives To explore the relationship between depressive symptoms during a first episode of mania, inflammatory parameters and patient functionality during the follow-up. Method We included in the study 92 are patients with a first manic episode and 92 matched healthy controls. We compared 13 inflammatory/oxidative stress parameters measured at baseline (TFNα, IL6, PGE2, MCP1, TBARS, NO2, SOD, CAT, GSHTOT, GSSG, GSHfree, GPx, TAS) between both groups. Between patients, 46 presented pure mania (PM) (no depressive symptoms) and 46 mixed mania (MM) (with depressive symptoms). We explored the influence of inflammatory factors in functionality, exploring differences between PM and MM. To measure patients’ general functioning one year after illness onset, we used the Functional Assessment Short Test (FAST). Results We found significant differences in TFNα, MCP1 and TBARS (higher in patients) and in SOD, GSHtot, GSSG, GSHfree, GPx and TAS levels (lower in patients). Only In MM group, there was a significant influence of SOD and GSHfree in FAST scores suggesting that a higher antioxidant levels at baseline the patient functionality improves one year after. Conclusions Some parameters of oxidative stress at baseline are related with patient's functionality one year after the first episode of mania, but only when mania debuts with depressive symptons simultaneously.
