RESUMO
This randomized, placebo-controlled trial investigated the tolerance, efficacy, and nutritional benefit of combining chemotherapeutic treatment of intestinal helminths and lymphatic filariasis. Children were infected with Ascaris (30.7%), Trichuris (53.4%), and hookworm (9.7%) with 69.9% having more than one of these parasites. A total of 15.8% of the children had Wuchereria bancrofti microfilariae. Children were randomly assigned treatment with placebo, albendazole (ALB), diethylcarbamazine (DEC), or combined therapy. The combination of DEC/ALB reduced microfilarial density compared with placebo, ALB, or DEC (P < or = 0.03). Albendazole and DEC/ALB reduced the prevalence of Ascaris, Trichuris, and hookworm more than placebo or DEC (P < or = 0.03). Among Trichuris-infected children, those receiving ALB and DEC/ALB demonstrated greater gains in weight compared with placebo (P < or = 0.05). Albendazole and DEC/ALB were equally efficacious in treating intestinal helminths and for children with W. bancrofti microfilaremia, DEC/ALB was more effective than DEC, with no increase in severity of adverse reactions.

To assess the clinical findings associated with detection of adult Wuchereria bancrofti worms on ultrasound, 186 schoolchildren in a filariasis-endemic area of Haiti underwent physical and ultrasonographic examinations. The filaria dance sign (FDS) of adult W. bancrofti was detected in the inguinal and crural lymphatics of 28 (15%) children. FDS detection was more common in older children (P = 0.003) and in those with a history of inguinal lymph node inflammation (P = 0.002) or crural lymphadenopathy on physical exam (P = 0.01). Twenty-five FDS-positive children were reexamined after three annual cycles of mass treatment for lymphatic filariasis (LF). The total number of adult worm nests detected by ultrasound decreased from 29 to 4 (P =0.0001). FDS and lymphangiectasia were detected in the intrascrotal (N = 3) and inguinal (N = 1) lymphatic vessels of three postpubescent boys. This study demonstrates clinical and subclinical findings of LF in FDS-positive children.
