Helicobacter pylori (H. pylori), is a common infection in pregnant women accompanied by variations in the levels of the IgM, IgA and IgG antibody isotypes. The variations of anti-H. pylori antibodies during and after pregnancy, and the extent of protection they provide to the mother and the fetus are not completely understood.
To investigate the changes of the anti-H. pylori IgM, IgA and IgG levels in healthy Omani pregnant women during pregnancy and 3 months after delivery.
Serum samples obtained from 70 Omani healthy pregnant women, with no history of autoimmune diseases, were tested for anti-H. pylori IgM, IgA and IgG in the first trimester of pregnancy and 3 months after delivery. In parallel and as a control group, sera obtained from a group of 70 healthy non-pregnant Omani women were tested. The levels of anti-H. pylori IgM, IgA and IgG were measured using standard Enzyme Linked Immunosorbent Assays (ELISAs).
Anti-H. pylori IgA levels were found to be significantly higher during pregnancy (p=0.046) and after delivery (p=0.02) when compared to the control group. Moreover, a significant increase in the levels of anti-H. pylori IgM, IgA and IgG was detected after delivery (p=0.002) when compared to the levels during pregnancy.
Pregnancy is associated with an increase in the levels of anti-H. pylori IgA antibodies. In addition, anti-H. pylori IgM, IgG and IgA antibody levels increase after delivery.
幽门螺杆菌(H. pylori)是孕妇中常见的感染菌,伴有IgM、IgA和IgG抗体亚型水平的变化。孕期及产后抗幽门螺杆菌抗体的变化情况,以及它们为母亲和胎儿提供的保护程度尚未完全明确。
研究阿曼健康孕妇孕期及产后3个月抗幽门螺杆菌IgM、IgA和IgG水平的变化。
收集70名无自身免疫性疾病史的阿曼健康孕妇的血清样本,在孕早期及产后3个月检测抗幽门螺杆菌IgM、IgA和IgG。同时,收集70名健康非孕阿曼女性的血清作为对照组进行检测。采用标准酶联免疫吸附测定(ELISA)法测定抗幽门螺杆菌IgM、IgA和IgG水平。
与对照组相比,孕期(p = 0.046)及产后(p = 0.02)抗幽门螺杆菌IgA水平显著升高。此外,与孕期水平相比,产后抗幽门螺杆菌IgM、IgA和IgG水平显著升高(p = 0.002)。
孕期与抗幽门螺杆菌IgA抗体水平升高有关。此外,产后抗幽门螺杆菌IgM、IgG和IgA抗体水平升高。
