Efficacy and safety of famciclovir for treating mucocutaneous herpes simplex infection in HIV-infected individuals
Bibliographic record
Abstract
OBJECTIVE: To compare the efficacy and safety of 7 days' treatment with famciclovir 500 mg twice a day versus acyclovir 400 mg five times a day, for mucocutaneous herpes simplex virus (HSV) infection in HIV-infected individuals. DESIGN: Randomized, double-blind, parallel-group study to demonstrate equivalence for the primary efficacy parameter. SETTING: Forty-eight hospital-based or specialist public-health clinics in 12 countries. PATIENTS: Two-hundred and ninety-three HIV-positive patients with recurrent HSV infection (orolabial or genital) starting treatment within 48 h of first appearance of herpetic lesions. MAIN OUTCOME MEASURES: Proportion of patients developing new lesions during treatment (primary outcome measures); Time to complete healing of lesions, time to cessation of viral shedding, time to loss of lesion-associated symptoms, number of withdrawals due to treatment failure (secondary outcome measures). RESULTS: Equivalence was defined prospectively and famciclovir was equivalent to acyclovir in preventing new lesion formation: new lesions occurred in 16.7% and 13.3% of patients, respectively [difference, 3.4%; 95% confidence interval (CI), -4.8-11.5]. The groups were comparable in time to complete healing (median 7 days for both groups; hazard ratio, 1.01; 95% CI, 0.79-1.29; P = 0.95), cessation of viral shedding (median of 2 days [hazard ratio = 0.93; 95% C.I. 0.68, 1.27; p = 0.64]), and loss of lesion-associated symptoms (median 4 days; hazard ratio, 0.99; 95% CI, 0.75-1.30; P = 0.93). Similar numbers in each group withdrew because of treatment failure. There were no differences between groups in the incidence of adverse events. CONCLUSIONS: Famciclovir given twice a day is as effective and well tolerated as high-dose acyclovir for mucocutaneous HSV infections in HIV-infected individuals, and has the convenience of less frequent dosing.

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.
