The adverse consequences of heavy Trichuris infection
Insights
Heavy Trichuris trichiura infection significantly impacts children's nutritional status and increases co-infections. Treatment improved health, showing the importance of addressing whipworm infections in pediatric populations.
Area of Science:
- Medical Research
- Infectious Diseases
- Pediatrics
Background:
- Trichuris trichiura (whipworm) infection is a prevalent soil-transmitted helminthiasis.
- Heavy infections can lead to significant morbidity in children, including malnutrition and increased susceptibility to other infections.
Purpose of the Study:
- To assess the impact of heavy Trichuris trichiura infection on pediatric nutritional status and co-infections.
- To evaluate the clinical and nutritional outcomes following treatment for heavy Trichuris trichiura infection.
Main Methods:
- Comparison of children with heavy Trichuris trichiura infection (Group A) versus controls with light/no infection (Group B).
- Anoscopy for diagnosing heavy Trichuris trichiura infection.
- Nutritional status assessment, physical examinations, and monitoring of concomitant bacterial and protozoal infections before and after treatment.
Main Results:
- Children with heavy Trichuris trichiura infection exhibited poorer nutritional status and higher rates of bacterial and protozoal co-infections, including invasive amoebiasis.
- Treatment led to significant improvements in nutritional parameters, reduction in symptoms, and decreased rates of co-infections.
- Concomitant enteropathogens (Entamoeba histolytica, bacterial enteropathogens) did not significantly impact clinical or nutritional status in subgroups.
Conclusions:
- Heavy Trichuris trichiura infection is associated with significant negative health impacts in children.
- Treatment is effective in improving nutritional status and reducing co-infections.
- Further research may be needed to understand the complex interplay between Trichuris trichiura and other enteropathogens.
Abstract:
Sixty-seven children with heavy Trichuris trichiura infection (Group A) were compared to 73 control children of similar socio-economic status but with light or no T. trichiura (Group B), for nutritional status, rates of concomitant bacterial and protozoal, and symptoms and clinical signs associated with heavy T. trichiura infection. Anoscopy was used to determine heavy T. trichiura infection. Measurements and physical examination were done on Group A on admission to and discharge from hospital; 46% were seen on follow-up visit two to eight months later. Children in Group B were seen only once. There were significant differences for nutritional status (p less than 0.01) and rates of bacterial and protozoal co-infection (p less than 0.01) and a significantly greater rate of invasive amoebiasis in Group A. After treatment, nutritional parameters of Group A children improved significantly, symptoms and clinical signs decreased and there was also a significant decrease in the rate of concomitant bacterial and protozoal infection. Subgroups of Group A children, with and without concomitant enteropathogens, revealed that infection with Entamoeba histolytica and bacterial enteropathogens had had no significant impact on clinical and nutritional status.
