Abstract

Antibody titres to Campylobacter pyloridis in serum and gastric juice were estimated by an enzyme linked immunosorbent assay (ELISA) to whole organisms obtained from bacterial culture in 39 patients with non-ulcer dyspepsia. Whereas 20 of the 21 patients with chronic gastritis had gastric C pyloridis, 17 patients with no C pyloridis had normal histology in the gastric antrum and body. Significantly raised serum IgG and IgA antibody titres to C pyloridis were found in colonised patients with gastritis. Patients with raised IgG antibody to C pyloridis were also shown to have significantly raised titres to other Campylobacter species, suggesting antigenic cross reactivity. Gastric juice antibodies were also studied and IgA titres to C pyloridis were detected in a proportion of patients with gastritis, together with low levels of IgM, but no IgG.

摘要

采用酶联免疫吸附测定(ELISA)法,对39例非溃疡性消化不良患者细菌培养获得的全菌进行检测,以评估血清和胃液中幽门弯曲菌的抗体滴度。21例慢性胃炎患者中有20例胃内存在幽门弯曲菌,17例无幽门弯曲菌的患者胃窦和胃体组织学正常。在患有胃炎且细菌定植的患者中,发现血清中针对幽门弯曲菌的IgG和IgA抗体滴度显著升高。对幽门弯曲菌IgG抗体升高的患者研究还发现,其针对其他弯曲菌属的抗体滴度也显著升高,提示存在抗原交叉反应。同时对胃液抗体进行了研究,部分胃炎患者检测到针对幽门弯曲菌的IgA滴度,同时伴有低水平的IgM,但未检测到IgG。
