We studied the frequency of parasitic infection and associated clinical symptoms in children who attended general pediatric and dental clinics at UCLA. Parasites were detected in stool specimens of 40 (38%) of the 1-4 children completing the study. Protozoan parasites were recovered in 39 (38%); one child had whipworm eggs. Parasites included Dientamoeba fragilis in 22 (21%) children and Giardia lamblia in 18 (17%) children; commensals were observed in 15 (14%) children. Parasitic infection was more frequent in younger children, those with a history of immigration or foreign travel and those attending a day care center. A significant proportion of children with parasites had vague gastrointestinal complaints; however, parasites had not been considered as the etiologic agent by the parent or child's physician. Anorexia, irritability and gas were frequent in children with G. lamblia; abdominal pain was more frequent in those with D fragilis. Intestinal parasitic infection should be considered in children with vague gastrointestional complaints, particularly those in endemic areas, with a history of foreign travel or immigration or attending a day care center. Siblings of infected children should have stool examination even if asymptomatic.
我们研究了在加州大学洛杉矶分校普通儿科和牙科诊所就诊的儿童中寄生虫感染的频率及相关临床症状。在完成研究的104名儿童中，40名（38%）儿童的粪便标本中检测到寄生虫。39名（38%）儿童检测到原生动物寄生虫；一名儿童有鞭虫卵。寄生虫包括22名（21%）儿童感染脆弱双核阿米巴，18名（17%）儿童感染蓝氏贾第鞭毛虫；15名（14%）儿童观察到共生菌。年龄较小的儿童、有移民或国外旅行史的儿童以及在日托中心的儿童寄生虫感染更为常见。很大一部分感染寄生虫的儿童有模糊的胃肠道不适症状；然而，家长或儿童医生并未将寄生虫视为病因。感染蓝氏贾第鞭毛虫的儿童常出现厌食、易怒和腹胀；感染脆弱双核阿米巴的儿童腹痛更为常见。对于有模糊胃肠道不适症状的儿童，尤其是那些来自流行地区、有国外旅行或移民史或在日托中心的儿童，应考虑肠道寄生虫感染。即使无症状，感染儿童的兄弟姐妹也应进行粪便检查。
