Abstract

fetched live from OpenAlex

BACKGROUND: Depression complicates interferon-based hepatitis C virus (HCV) antiviral therapy in 10% to 40% of cases, and diminishes patient well-being and ability to complete a full course of therapy. As a consequence, the likelihood of achieving a sustained virological response (SVR [ie, permanent viral eradication]) is reduced. OBJECTIVE: To systematically review the evidence of whether pre-emptive antidepressant prophylaxis started before HCV antiviral initiation is beneficial. METHODS: Inclusion was restricted to randomized controlled trials in which prophylactic antidepressant therapy was started at least two weeks before the initiation of HCV antiviral treatment. Studies pertaining to patients with active or recent depressive symptoms before commencing HCV antiviral therapy were excluded. English language articles from 1946 to July 2012 were included. The MEDLINE, Embase and Cochrane Central databases were searched. Where possible, meta-analyses were conducted evaluating the effect of antidepressant prophylaxis on SVR and major depression as well as on Montgomery-Asberg Depression Rating Scale and Beck Depression Index scores at four, 12 and 24 weeks. The Cochrane Collaboration tool was used to assess bias risk. RESULTS: Six randomized clinical trials involving 522 patients met the inclusion criteria. Although the frequency of on-treatment clinical depression was decreased with antidepressant prophylaxis (risk ratio 0.60 [95% CI 0.38 to 0.93]; P=0.02; I2=24%), no benefit to SVR was identified (risk ratio 1.08 [95% CI 0.74 to 1.57]; P=0.69; I2=58%). CONCLUSION: This practice is not justified to improve SVR in populations free of active depressive symptoms leading up to HCV antiviral therapy.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
