Hookworm Infections

Abstract Background: Despite the existence of a population-based control program using single dose albendazole or mebendazole as a preventive chemotherapy, hookworm transmission remains high. It causes a negative impact on the growth and school performance of children. In connection to this preventive chemotherapy, different studies produced conflicting results. This study aimed at evaluating the efficacy of single (500mg) versus multiple doses (100mg twice a day during three consecutive days) of mebendazole against hookworm infections among school-aged children. Methods: This randomized open-label clinical trial took place among school-aged children (6-14 years old) in Burie and Debre Elias towns, Northwest Ethiopia. Using simple randomization, eligible hookworm-positive children were allocated (1:1) to either a single or multiple dose treatment arms. Stool samples were collected and processed using McMaster method at baseline and follow-up period (14-21 days after treatment). Only laboratory technicians were blinded. The cure and egg reduction rates which were assessed after 14-21 days of treatment were the primary and secondary therapeutic outcome measures against hookworm infections, respectively. An independent t-test was used to compare group means, and logistic regression was used to calculate odds ratio (OR). P-value < 0.05 at 95% CI was considered statistically significant. Result: 108 children, 54 in each treatment arm had completed baseline data and received allocated treatment. 103 children had completed follow-up data records and included for the final efficacy analysis. Cure rate against hookworm was significantly higher in the multiple dose (96.1%) than in the single dose (30.8%) with OR=55.125; 95% CI: 11.92-254.9; P < 0.001. The egg reduction rate in the multiple dose treatment arm (99.5%) was also significantly higher than in the single dose arm (68.9%) with difference t (101) =5.38; 95% CI 230.95-505.36; P < 0.001. Conclusion: The single dose regimen of mebendazole for the treatment of hookworm infections showed poor cure and egg reduction rates, while the multiple dose revealed satisfactory. Although multiple dose regimen administration is a bit more complex than the single dose, we strongly encourage replacing it with multiple dose regimen during deworming programs in hookworm endemic areas.

Abstract Background : Despite the existence of population-based control program using single dose albendazole or mebendazole as a preventive chemotherapy, Hookworm disease transmissions remains high. It causes a negative impact on the growth and school performance of children. In connection to this preventive chemotherapy, different studies produced conflicting results. This study evaluated the efficacy of single (500mg) versus multiple doses (100mg twice a day during three consecutive days) of mebendazole against Hookworm infections among school aged children. Methods : This randomized single-blinded clinical trial took place among school-aged children (6-14 years old) in Burie and Debre Elias towns, Northwest Ethiopia. Using simple randomization, eligible Hookworm positive children were allocated (1:1) to either a single or multiple doses treatment arm. Stool samples were collected and processed using McMaster method at baseline and follow-up period (14-21 days after treatment). Main outcome measures : The cure rate against Hookworm and egg reduction rate for determining the changes in infection intensity were the main outcome measures after 14-21 days following dosing. An independent t-test was used to compare group means, and logistic regression was used to calculate odds ratio (OR). P-value < 0.05 at 95% CI was considered statistically significant. Result: 109 children were participated in both treatment arms. Cure rate against Hookworm was significantly higher in the multiple dose (96.1%) than in the single dose (30.8%) with (OR=55.125; 95% CI: 11.92-254.9; P < 0.001). The egg reduction rate in the multiple dose treatment arm (99.5%) was also significantly higher than in the single dose arm (68.9%) with difference (t (101) =5.38; 95% CI 230.95-505.36; P < 0.001). Conclusion : The single dose regimen of mebendazole for the treatment of Hookworm infection showed poor efficacy, while the multiple dose revealed satisfactory efficacy. Moreover, infection intensity reduction was not achieved following single dosing. Therefore, we strongly recommend replacing the single dose mebendazole regimen with multiple dose regimen during deworming program in hookworm endemic areas.
