Helicobacter-negative gastritis is diagnosed when no organisms are detected in a gastric mucosa with typical features of Helicobacter gastritis (Hp-gastritis). If Helicobacter-negative gastritis consisted mostly of 'missed' Helicobacter infections, its prevalence should represent a constant percentage of these infections in a population, and their clinico-epidemiological features would overlap.
To compare the epidemiologic patterns of Hp-positive and Hp-negative gastritis.
From a pathology database, we extracted demographic, clinical and histopathological data from patients with gastric biopsies (1.2008-12.2013). We allocated patients to high (≥12%) and low (≤6%) H. pylori prevalence regions defined by ZIP code-based data. The prevalence of H. pylori-positive and -negative gastritis by sex, age and state were expressed as a per cent of the total study population stratified accordingly.
Of 895 323 patients, 10.6% had Hp-gastritis and 1.5% Helicobacter-negative gastritis. Hp-gastritis, but not Helicobacter-negative gastritis, was more common in males than females (OR 1.17, 95% CI: 1.16-1.19). While Hp-gastritis was more prevalent in high than in low-prevalence areas (OR 3.65, 95% CI: 3.57-3.74), Helicobacter-negative gastritis was only minimally affected by the underlying H. pylori prevalence (1.7% vs. 1.5%). The age-specific prevalence of Hp-gastritis peaked in the 4th to 5th decades; Helicobacter-negative gastritis exhibited a low and relatively flat pattern. The geographic distribution of H. pylori-positive and -negative gastritis showed no significant correlation. Intestinal metaplasia was found in 13.0% of patients with Hp-gastritis and in 6.1% of those with Helicobacter-negative gastritis (OR 0.43, 95% CI: 0.40-0.47).
These data suggest that Helicobacter-negative gastritis is, in the vast majority of cases, a nosologically and epidemiologically distinct entity that deserves further investigation.
当胃黏膜具有典型的幽门螺杆菌胃炎(Hp 胃炎)特征而未检测到任何病原体时,诊断为幽门螺杆菌阴性胃炎(Helicobacter-negative gastritis)。如果幽门螺杆菌阴性胃炎主要由“漏诊”的幽门螺杆菌感染组成,那么其患病率应代表人群中此类感染的恒定百分比,且其临床流行病学特征会重叠。
比较幽门螺杆菌阳性和阴性胃炎的流行病学模式。
我们从病理学数据库中提取了 2013 年 12 月至 2013 年 12 月期间接受胃活检的患者的人口统计学、临床和组织病理学数据。我们根据邮政编码数据将患者分配到高(≥12%)和低(≤6%)幽门螺杆菌患病率地区。按性别、年龄和状态分层,以总研究人群的百分比表示幽门螺杆菌阳性和阴性胃炎的患病率。
在 895323 名患者中,10.6%患有 Hp 胃炎,1.5%患有幽门螺杆菌阴性胃炎。与女性相比,男性更常见 Hp 胃炎(比值比 1.17,95%置信区间:1.16-1.19),但并非幽门螺杆菌阴性胃炎(比值比 1.17,95%置信区间:1.16-1.19)。虽然 Hp 胃炎在高患病率地区比低患病率地区更为普遍(比值比 3.65,95%置信区间:3.57-3.74),但幽门螺杆菌阴性胃炎受潜在幽门螺杆菌患病率的影响极小(1.7%比 1.5%)。Hp 胃炎的年龄特异性患病率在第 4 至 5 个十年达到峰值;幽门螺杆菌阴性胃炎的患病率较低且相对平坦。Hp 阳性和阴性胃炎的地理分布无明显相关性。肠化生在 Hp 胃炎患者中的发生率为 13.0%,在幽门螺杆菌阴性胃炎患者中的发生率为 6.1%(比值比 0.43,95%置信区间:0.40-0.47)。
这些数据表明,在绝大多数情况下,幽门螺杆菌阴性胃炎在病理和流行病学上都是一种不同的实体,值得进一步研究。
