Treatment of bipolar depression with minocycline and/or aspirin: an adaptive, 2×2 double-blind, randomized, placebo-controlled, phase IIA clinical trial

“Given evidence of chronic inflammation in bipolar disorder (BD), we tested the efficacy of aspirin and minocycline as augmentation therapy for bipolar depression.

"The absence of a significant interaction between the efficacy of aspirin treatment and baseline levels of CRP and/or IL-6 may reflect Type II error given the relatively small samples, but also may reflect the clinically non-significant anti-inflammatory effect of low-dose aspirin in autoimmune or other inflammatory disorders".

"In this regard, this first report of higher baseline 11-D-TXB2 levels in the BD sample relative to the control sample (Figure S2) is noteworthy as it suggests that the activity of the arachidonic acid pathway is elevated in a subset of individuals with BD, consistent with previous hypotheses".
