| Scientific title | Efficacy and safety of albendazole and mebendazole as single-dose or in combination with ivermectin against soil-transmitted helminth infections, particularly Trichuris trichiura, in schoolchildren in Zanzibar, Tanzania: a randomised controlled trial |
| Study acronym | Alben-Meben-Ivermect-Zanzibar |
| Study objectives | 1. Combination therapy with either albendazole or mebendazole plus ivermectin is more efficacious against Trichuris trichiura that single therapy with either albendazole or mebendazole 2. Current efficacy of either albendazole or mebendazole (single dose) is low due the long-term administration of these drugs in the national helminth control programme in Zanzibar 3. The FLOTAC® technique is more sensitive than the Kato-Katz technique for helminth egg detection |
| Ethics approval(s) | Ethikkommission beider Basel EKBB gave approval on the 15th January 2009 (ref: 13/09) |
| Health condition(s) or problem(s) studied | Soil-transmitted helminthiasis |
| Intervention | Four treatment groups as follows: 1. Single-dose albendazole; children will receive one tablet of albendazole (400 mg) and a placebo resembling ivermectin (number of tablets according to weight) 2. Mebendazole; children will receive a single dose of mebendazole (500 mg) and a placebo resembling ivermectin (number of tablets according to weight) 3. Albendazole plus ivermectin; children will receive one tablet of albendazole (400 mg) plus ivermectin tablets according to their weight (200 µg/kg) 4. Mebendazole plus ivermectin; children will receive one tablet of mebendazole (500 mg) plus ivermectin tablets according to their weight (200 µg/kg) The treatment for the four arms will be administered on a single day; follow-up is 3 - 4 weeks post-treatment. |
