Efficacy and Safety of MOX/ALB Co-administration

TrichuriasisAscariasis1 more

This study is a double-blind randomized controlled superiority trial aiming at providing evidence on the efficacy and safety of co-administered moxidectin and albendazole versus albendazole monotherapy (standard of care) against whipworm (T. trichiura) infections in adolescents and adults (12-60 years) in Côte d'Ivoire. One arm of patients will be treated with albendazole-ivermectin. As measure of efficacy of the treatment the cure rate (percentage of egg-positive subjects at baseline who become egg-negative after treatment) will be determined 14-21 days post-treatment.

Efficacy and Safety of MOX/ALB vs. IVM/ALB Co-administration

TrichuriasisAscariasis3 more

The aim of this randomized controlled trial is to provide evidence on the efficacy and safety of co-administered moxidectin and albendazole compared to co-administered ivermectin and albendazole, and to assess the efficacy of the drug combinations compared to monotherapies in adolescents aged 12-19 years against infection with T. trichiura. The efficacy of the different treatments will be determined 14-21 days, 5-6 weeks and 3 months post-treatment. Two fecal samples will be collected at each time-point assessment. The geometric mean based egg reduction rate (ERR) of T. trichiura egg counts will be assessed by Kato-Katz microscopy pre-treatment and 14-21 days post-treatment. This trial will be conducted as a school-based study on Pemba Island (Zanzibar, Tanzania).

Effectiveness of Combined Albendazole and Ivermectin Treatment for Intestinal Worm Infections

AscariasisTrichuriasis3 more

The aim of this study is to compare the efficacy and impact on growth of two drug treatments against intestinal worms in schoolchildren from a rural area of Guatemala. According to the World Bank, these intestinal worms are one of the top causes of childhood health problems in many areas of the developing world (The World Bank, 1993). Infected children are more likely to have inadequate nutrition due to the worm infections and are more likely to be shorter in height and weigh less than children who are not infected. After collecting height and weight information, we will split the children into two groups. One group will receive albendazole and the other group will receive combined albendazole/ivermectin. Both groups will be receiving albendazole, the current standard of care treatment. Ivermection is expected to improve efficacy and nutritional benefit as well as add increased scope of treatment for the worm Strongyloides, and ectoparasites such as scabies and head lice. Both treatment regimens and the combination have been used millions of times in the developing world and are safe to use. Co-administration of drugs would be a more efficient use of the opportunity to access schoolchildren and provide deworming treatment.

Efficacy Albendazole and Levamisole Against STH on Unguja

AscariasisTrichuriasis

Field epidemiological studies undertaken during 2005 in four village locations in Northern Unguja, Zanzibar examined mothers and their pre-school aged children for helminth infections. The prevalence of Ascaris lumbricoides was found to have remained relatively high despite community-wide treatment with the mass administration of Albendazole (a WHO recommended de-wormer) in coordination with community vitamin A supplementation. One hypothesis for this is that the children and mothers had Ascaris infections more tolerant to Albendazole that subsequently failed to clear. It is necessary to compare the present drug efficiency of Albendazole (first-line de-wormer) with Levamisole (second-line de-wormer) on STH infections such patients a case-control setting to shed light on the putative resistance of local Ascaris/Trichuris to albendazole. In so doing, this should clarify whether there is resistance developing towards Albendazole and have possible implications for introducing combination therapies of Levamisole and Albendazole for first line de-worming mothers and their children in the future.

Impact of Repeated Anthelmintic Treatment on the Risk of Malaria in Kenyan School Children

Intestinal HelminthiasisAscariasis2 more

Many school children in Kenya are infected with plasmodia and helminth species and are at risk of coinfection. It has been suggested that the immune response evoked by helminth infections may modify immune responses to plasmodia species and consequently alter infection and disease risks. However, studies conducted to date have been typically cross-sectional and produced conflicting results, and there is a need for longitudinal studies to better understand the clinical consequences for individuals harbouring coinfection. This study aims to investigate the impact of intensive (once every 3 months) anthelminthic treatment versus annual treatment on the risk of clinical malaria and on immune responses among school children aged 5-14 years in Western Province. Specifically, this study aims to investigate the impact of intensive anthelminthic treatment on (i) the incidence of clinical malaria in school children, assessed using active case detection; (ii) the prevalence and density of Plasmodium spp. infection, using repeat cross-sectional surveys; and (iii) malaria and helminth specific immune responses. The study hypothesis is that intensive anthelminthic treatment among children infected with either Ascaris lumbricoides or hookworm modifies human host immune responses to plasmodia and helminth infections, and therefore alters the risk of Plasmodium infection and clinical disease. This individually randomised trial will recruit 1,450 children aged 5-14 years found to be infected with either Ascaris lumbricoides or hookworm species. Recruited children will be randomized to receive albendazole treatment either every three months or annually and monitored through periodic surveillance for clinical malaria episodes over 18 months. In addition, blood samples will be collected from sub-sample of children and screened for malaria specific immunoglobulin (Ig)G1 and IgG3 and helminth specific IgE, IgG2, IgG4 and IgM. Cell culture supernatants will be assayed for interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-10, IL-5, IL-4 and IL-2.

Soil-transmitted Helminth Reinfection Rates After Single and Repeated School Hygiene Education

HelminthiasisAscaris Infection4 more

Soil-transmitted helminth (STH) infections caused by Ascaris lumbricoides, Trichuris trichiura, or hookworm, affect approximately 1.5 millions individuals primarily in tropical and subtropical regions. STHs infections have been associated with delay in growth and development in children. The prevalence in Indonesia varied from 45% to 65%, but in poor sanitation areas the prevalence can increased to 80%. World Health Organization currently recommends mass treatment with benzimidazoles and health hygiene education to control the disease. In this study we evaluated the effectiveness of single and four-monthly health hygiene education to STH reinfection rates among school-aged children in Mandailing Natal district, North Sumatera province, Indonesia.
