作者用酶联免疫吸附检查(ELISA)测定幽门螺旋菌(HP,以前称幽门弯曲菌)血清抗体,调查了冈比亚小儿的HP感染。对20例慢性腹泻或消瘦的患儿作胃镜检查,其中16例患有胃窦部胃炎,13例患胃窦胃炎的小儿血循环中存在抗—HPIgG抗体,8例胃粘膜活检标本组织学鉴别出HP的小儿,其血循环抗体滴度超过100ELISA单位者8例,其余5例为40单位以上,而抗体在100单位以上者认为有活动性HP
The authors tested for H. pylori (HP, formerly H. pylori) serum antibodies by enzyme-linked immunosorbent assay (ELISA) and investigated HP infection in children in the Gambia. Gastroscopy was performed on 20 children with chronic diarrhea or emaciation. Among them, 16 patients had gastric gastritis, 13 had anti-HPIgG antibody in pediatric patients with gastric gastritis, and 8 patients with gastric mucosal biopsy specimens were histologically identified HP pediatric, the blood circulation antibody titer more than 100ELISA unit in 8 cases, the remaining 5 cases for more than 40 units, while the antibody in 100 units or more are considered active HP
