Efficacy and Safety of Albendazole and High-Dose Ivermectin Coadministration in School-Aged Children Infected With <i>Trichuris trichiura</i> in Honduras: A Randomized Controlled Trial
Bibliographic record
Abstract
BACKGROUND: The efficacy of currently available anthelminthics against Trichuris trichiura infections is significatively lower than for other soil-transmitted helminths. The combination of ivermectin (IVM) and albendazole (ALB) has shown significant improvements in efficacy. METHODS: Safety and efficacy randomized controlled clinical trial comparing 3 experimental regimens against ALB monotherapy for the treatment of T. trichiura infections in northern Honduras. Infected children were randomized to 4 treatment arms: arm 1, single-dose ALB (400 mg); arm 2, single-dose ALB (400 mg) plus IVM (600 μg/kg); arm 3, ALB (400 mg) for 3 consecutive days; or arm 4, ALB (400 mg) plus IVM (600 μg/kg) for 3 consecutive days. Efficacy was measured based on the egg reduction and cure rates, both assessed 14-21 days after treatment, using the Kato-Katz method. Safety was evaluated by analyzing the frequency and severity of adverse events. RESULTS: Of 176 children randomized to 1 of the 4 treatment arms, 117 completed treatment and follow-up. The egg reduction rates for arms 1, 2, 3, and 4 were 47.7%, 96.7%, 72.1%, and 100%, respectively; with P values <.001 for comparisons between IVM groups and ALB-only arms. The cure rates were 4.2%, 88.6%, 33.3%, and 100%, respectively. A total of 48 adverse events (85.4% mild) were reported in 36 children. CONCLUSIONS: The combined use of ALB and high-dose IVM is a highly effective and well tolerated treatment for the treatment of T. trichiura infections, offering significantly improved treatment for the control of this infection. CLINICAL TRIALS REGISTRATION: NCT04041453.

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.
