Efficacy and Safety of Pegylated Interferon Alfa-2a or Alfa-2b Plus Ribavirin for the Treatment of Chronic Hepatitis C in Children and Adolescents: A Systematic Review and Meta-analysis
Bibliographic record
Abstract
BACKGROUND: A systematic review and meta-analysis were conducted to examine the efficacy and safety of pegylated interferon (peg-IFN) alfa-2a and peg-IFN alfa-2b plus ribavirin (RBV) in children and adolescents with chronic hepatitis C virus (HCV). METHODS: Medline, Embase, and Cochrane Central Register of Controlled Trials were searched. Clinical trials examining peg-IFN alfa-2a or peg-IFN alfa-2b plus RBV among persons ages 3-18 years with HCV were included. Data were abstracted for complete early virologic response (EVR), sustained virologic response (SVR), relapse, treatment discontinuations, hematologic and dermatologic adverse events, and growth inhibition. RESULTS: Eight trials met the inclusion criteria. Results indicate that 70% of subjects (95% confidence interval [CI], 58%-81%) achieved EVR, and 58% (95% CI, 53%-64%) achieved SVR. EVR and SVR were higher for those with HCV genotypes 2/3 than 1/4. Discontinuation due to adverse events and discontinuation due to viral breakthrough were each 4%, discontinuation due to a lack of response was 15%, and relapse was 7%. Anemia, neutropenia, leukopenia, and thrombcytopenia were 11%, 32%, 52%, and 5%, respectively. Alopecia, injection site erythema, and pruritus were 13%, 27%, and 10%, respectively. Small growth inhibitions were observed during treatment. CONCLUSION: The results of this meta-analysis indicate that peg-IFN/RBV combination treatment is effective and safe in treating children and adolescents with HCV.

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.
