Single dose oral treatment in urinary schistosomiasis: a double blind trial. 1983

R N Pugh, and C H Teesdale

A double blind trial of three oral preparations given in single doses for the treatment of Schistosoma haematobium infection was carried out in schoolchildren; selection was biased towards those who excreted large quantities of eggs. Praziquantel 40 mg/kg was the most effective drug giving a greater than 97% reduction in egg output six months after treatment; combined treatment with niridazole 25 mg/kg and metrifonate 10 mg/kg gave a reduction of greater than 92% and metrifonate 10 mg/kg alone a reduction of greater than 86%. Fewer children continued to have moderate to heavy infections (excretion greater than 124 ova/10 ml urine) six months after treatment with praziquantel (5%) and the combined regimen (7%) than with metrifonate (16%). Though our findings show that praziquantel appears to be the most effective and convenient drug available for individuals with S haematobium infection, the combined regimen is a cheaper alternative for treatment where cost is important and parasitological cure not an essential objective.
