Stool specimens of 104 primary schoolchildren (mean+/-SD age = 8.2+/-0.3 years) were examined for helminth eggs and for occult blood to investigate the possibility that trichuriasis causes occult intestinal bleeding in the absence of the overt Trichuris dysentery syndrome. A commercially available guaiac test was used to detect fecal occult blood. Sixty-one children had Trichuris infection, 11 of whom had heavy infections (> 10,000 eggs per gram of feces [epg]), and 53 had Ascaris infections. No hookworm infection was detected. Baseline screening yielded only one weakly positive occult blood test result in a child with a light (800 epg) Trichuris infection. Serial stool occult blood testing on the 11 subjects with heavy trichuriasis and 8 uninfected controls yielded a single weakly positive result in the control group. The results provide no evidence that trichuriasis predisposes to significant occult gastrointestinal bleeding in children in the absence of the dysenteric syndrome.
对104名小学生（平均年龄±标准差=8.2±0.3岁）的粪便标本进行了蠕虫虫卵和潜血检查，以调查在没有明显的鞭虫痢疾综合征的情况下，鞭虫病是否会导致隐匿性肠道出血。使用市售的愈创木脂试验检测粪便潜血。61名儿童感染了鞭虫，其中11名感染严重（每克粪便虫卵数>10,000个[epg]），53名儿童感染了蛔虫。未检测到钩虫感染。基线筛查中，仅一名轻度（800 epg）鞭虫感染儿童的潜血试验结果呈弱阳性。对11名重度鞭虫病患者和8名未感染对照者进行系列粪便潜血检测，对照组仅出现一次弱阳性结果。结果表明，在没有痢疾综合征的情况下，没有证据表明鞭虫病会使儿童易患明显的隐匿性胃肠道出血。
