Effect of biologics on depressive symptoms in patients with psoriasis: a systematic review
Bibliographic record
Abstract
BACKGROUND: Twenty to fifty percent of patients with psoriasis have depressive symptoms. OBJECTIVE: To describe the effects of biologics (tumour necrosis factor inhibitors [TNFi] or interleukin 12/23 inhibitors [IL-12/23i]) on depressive symptoms in patients with psoriasis. METHODS: Electronic databases were searched for randomized controlled trials (RCTs) examining the effects of biologics on depressive symptoms in adults with psoriasis. RESULTS: Of the 305 publications identified, three RCTs were included in a systematic review. In a trial evaluating ustekinumab, mean change in Hospital and Anxiety Depression Rating Scale at 24 weeks from baseline was 3.1 with ustekinumab (P < 0.001) vs. 0.21 with placebo (not significant). In a trial evaluating adalimumab, mean change in Zung Self-Rating Depression Scale at 12 weeks from baseline was -6.7 with adalimumab vs. -1.5 with placebo. In a trial evaluating etanercept, the between-group difference at 12 weeks in Beck Depression Inventory Scale was 1.8 (95% CI: 0.6, 2.90) in favour of etanercept over placebo. Limitations are that diagnostic criteria for depression were not used and scales and data from individual RCTs could not be combined. CONCLUSION: Adalimumab, etanercept and ustekinumab were associated with statistically significant reductions in depressive symptom scores using various scales in patients with moderate-to-severe psoriasis.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
