Abstract

Background: No study has gathered evidence from all randomized clinical trials (RCT s) with anti‐inflammatory drugs measuring antidepressant effects including a detailed assessment of side‐effects and bias. Methods: We performed a systematic review identifying RCT s published prior to January 1, 2018, studying antidepressant treatment effects and side‐effects of pharmacological anti‐inflammatory intervention in adults with major depressive disorder (MDD) or depressive symptoms. Outcomes were depression scores after treatment, remission, response, and side‐effects. Pooled standard mean differences (SMD) and risk ratios (RR) including 95% confidence intervals (95%‐CI) were calculated. Results: We identified 36 RCT s, whereof 13 investigated NSAID s (N = 4214), 9 cytokine inhibitors (N = 3345), seven statins (N = 1576), 3 minocycline (N = 151), 2 pioglitazone (N = 77), and 2 glucocorticoids (N = 59). Anti‐inflammatory agents improved depressive symptoms compared to placebo as add‐on in patients with MDD (SMD = −0.64; 95%‐CI = −0.88, −0.40; I2 = 51%; N = 597) and as monotherapy (SMD = −0.41; 95%‐CI = −0.60, −0.22; I2 = 93%, N = 8825). Anti‐inflammatory add‐on improved response (RR = 1.76; 95%‐CI = 1.44–2.16; I2 = 16%; N = 341) and remission (RR = 2.14; 95%‐CI = 1.03–4.48; I2 = 57%; N = 270). We found a trend toward an increased risk for infections, and all studies showed high risk of bias. Conclusion: Anti‐inflammatory agents improved antidepressant treatment effects. Future RCT s need to include longer follow‐up, identify optimal doses and subgroups of patients that can benefit from anti‐inflammatory intervention.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-08.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
