哮喘是一种非常常见的呼吸道疾病,其特征是存在细胞因子介导的气道炎症,导致平滑肌收缩、水肿,并且在某些情况下会导致进行性气道损伤。鉴于我们最近发现支气管扩张症中幽门螺杆菌血清流行率增加,我们测定了哮喘受试者和对照受试者中幽门螺杆菌特异性 IgG 的血清水平。前瞻性招募了总共 90 名连续哮喘患者 [平均年龄 +/- SD 42.6+/-16 岁和 52 名女性 (F)] 和 97 名健康对照受试者(平均年龄 +/- SD 43.2+/-13.3 岁和 51 名女性 (F);P 分别 = 0.78 和 0.39)。哮喘受试者和对照受试者之间幽门螺杆菌血清流行率没有显着差异(P>0.05)。血清幽门螺杆菌 IgG 水平与 FEV1 % 预测值、FVC % 预测值或哮喘持续时间不相关 (P>0.05)。与之前发表的血清流行病学研究结果类似,血清幽门螺杆菌 IgG 与年龄增加之间存在弱相关性(r = 0.43,P = 0.004)。尽管幽门螺杆菌感染与许多炎症性疾病存在血清流行病学关联,但我们的数据显示,我们当地患有轻度间歇性哮喘的中年哮喘患者没有这种关联。
Asthma is a very common respiratory disease which is characterized by the presence of cytokine-mediated airway inflammation leading to smooth muscle contraction, oedema and progressive airway damage in some cases. In light of our recent finding of an increased sero-prevalence of Helicobacter pylori in bronchiectasis, we have determined serum levels of H. pylori-specific IgG in asthmatic and control subjects. Altogether 90 consecutive asthmatic [mean age +/- SD 42.6+/-16 years and 52 female (F)] and 97 healthy control subjects (mean age +/- SD 43.2+/-13.3 years and 51 female (F); P = 0.78 and 0.39 respectively) were recruited prospectively. H. pylori sero-prevalence was not significantly different between asthmatic and control subjects (P>0.05). Serum H. pylori IgG levels did not correlate with FEV1 % predicted, FVC % predicted or duration of asthma (P>0.05). Similar to the results of previously published sero-epidemiological studies, there was a weak correlation between serum H. pylori IgG with increasing age (r = 0.43, P = 0.004). Despite the sero-epidemiological association of H. pylori infection with many inflammatory conditions, our data showed no such association for middle age asthmatic patients with mild intermittent asthma in our locality.
