Anti-Inflammatory Treatments Look Promising for Bipolar Depression
Inflammation has been linked to both unipolar and bipolar depression. New research shows that anti-inflammatory treatments may reduce bipolar depression, for which few treatments exist.
Researchers led by Jonathan Savitz divided people with bipolar depression into four groups. One group received two placebos, another received minocycline (a drug with neuroprotective and immune-modulating properties) plus a placebo, the third received aspirin plus a placebo, and the final group received both minocycline and aspirin. Of the 64 participants, those who took both minocycline and aspirin were most likely to respond to treatment and to enter remission. In people with body mass indexes (BMIs) above the median of 30, a sign of greater inflammation, 100% of those who received both anti-inflammatory drugs responded to treatment, compared to 36% of those who received aspirin alone, 33% of those who received minocycline alone, and 25% of those who received two placebos.
Dosages of the drugs were 100mg twice a day for minocycline and 81mg twice a day for aspirin. Savitz and colleagues believe that aspirin and minocycline must work particularly well together, and are modifying their study to more directly compare use of the two anti-inflammatory drugs together to the absence of anti-inflammatory treatments.
