Combination of eflornithine and melarsoprol for melarsoprol‐resistant Gambian trypanosomiasis
Bibliographic record
Abstract
OBJECTIVE: To evaluate the efficacy and toxicity of a combination of eflornithine and melarsoprol among relapsing cases of Gambian trypanosomiasis. METHODS: Forty-two late-stage Trypanosoma brucei gambiense trypanosomiasis patients relapsing after initial treatment with melarsoprol were treated with a sequential combination of intravenous eflornithine (100 mg/kg every 6 h for 4 days) followed by three daily injections of melarsoprol (3.6 mg/kg, up to 180 mg). They were then followed-up for 24 months. RESULTS: Two (4.8%) patients died during treatment. Of the 40 surviving patients, two had a treatment failure, 13 and 19 months after having received the combination therapy. By Kaplan-Meier analysis, the 2-year probability of cure was 93.3% (95% confidence interval: 84.3-100%). CONCLUSION: This sequential combination has an efficacy and a toxicity similar to a 7-day course of eflornithine monotherapy, but is easier to administer. Whether such therapeutic success corresponds tosynergism between eflornithine and melarsoprol, or merely means that 4 days of eflornithine monotherapy suffices for such patients, will need to be determined in a comparative trial.

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.
