Researchers report that targeting inflammation may offer a new way to treat depression. The study focused on people with depression who had high levels of inflammation. The team reviewed clinical trials in which participants received anti-inflammatory drugs or a placebo.
Overall, anti-inflammatory treatments reduced depressive symptoms and eased anhedonia, the inability to feel pleasure. The analysis also found no increase in serious side effects among people who received the drugs.
The authors noted these drugs are not approved by the FDA to treat depression, so psychiatric use would be off-label. One co-author said the result may make immunopsychiatry more relevant and could explain earlier mixed findings when studies did not select people by inflammatory status.
