Insights
Albendazole treatment for Trichuris trichiura in children did not improve growth rates and showed no effect on TNF-alpha levels. A concerning delay in growth was observed in the treatment group at six months.
Area of Science:
- Tropical medicine
- Pediatric helminthology
- Nutritional immunology
Background:
- Trichuriasis, a common soil-transmitted helminth infection, affects millions of schoolchildren globally.
- Subclinical infections can impact child development, including growth and inflammatory markers.
- Albendazole is a primary anthelmintic used for treating trichuriasis.
Purpose of the Study:
- To investigate the impact of albendazole on growth and TNF-alpha levels in asymptomatic schoolchildren with trichuriasis.
- To assess the efficacy of a standard albendazole regimen in this specific population.
Main Methods:
- A randomized, placebo-controlled trial was conducted with 37 asymptomatic schoolchildren (aged 6-7 years) in Malaysia.
- Participants received either albendazole (400 mg daily for 2 days) or a placebo.
- Anthropometric measurements and urinary TNF-alpha levels were assessed at baseline and at 3, 6, and 12 months post-treatment.
Main Results:
- The placebo group exhibited a significantly greater increase in height compared to the albendazole group (p = 0.04) at 6 months.
- No significant differences in urinary TNF-alpha levels were observed between the groups.
- No significant changes in TNF-alpha levels were found from baseline to 1 month post-treatment.
Conclusions:
- Albendazole treatment for light to moderate trichuriasis in asymptomatic schoolchildren was associated with a temporary delay in growth rate.
- The drug did not significantly alter TNF-alpha levels, suggesting inflammation is not the primary mechanism for the observed growth effect.
- Further research is warranted to elucidate the etiology of this growth delay and its long-term implications.
Abstract:
We studied asymptomatic primary schoolchildren in northeastern Malaysia with light to moderate trichuriasis to determine the effect of albendazole treatment on growth rates and TNF-alpha levels. Thirty-seven schoolchildren aged 6-7 years with stool samples positive for Trichuris trichiura and negative for other geohelminths and protozoa were randomized to receive albendazole 400 mg or a placebo daily for 2 days. Anthropometric parameters at baseline, 3, 6 and 12 months were compared between the 2 groups. The placebo group had a significantly greater increase in height (p = 0.04) than the albendazole treatment group. There were no significant differences in urinary TNF-alpha levels (p = 0.8) between the 2 groups and no significant changes between baseline and 1 month post-treatment levels. Further studies are needed to determine the etiology of this apparent association between the albendazole treatment group and the delay in growth rate at 6 months post-treatment.
