研究疾病:

自身免疫性胃炎(AIG),又称为A型胃炎,最早由Strickland等学者相对于B型胃炎(主要为幽门螺杆菌相关性胃炎)而定义。它是一种由CD4+T细胞介导的自身免疫性疾病,以胃体黏膜固有腺体萎缩常伴有肠上皮化生和(或)假幽门腺化生为特点。胃壁细胞被免疫系统破坏,导致吸收铁和维生素B12的能力逐渐下降。2019年日本一项纳入245例A型胃炎患者的多中心研究结果显示,合并胃癌者高达9.8%,其中神经内  

Target disease:

Autoimmune gastritis (AIG), also known as type A gastritis, was first defined by Strickland and others in relation to type B gastritis (mainly Helicobacter pylori-associated gastritis). It is an autoimmune disease mediated by CD4 T cells, characterized by atrophy of the gastric body mucosal glands, often accompanied by intestinal metaplasia and/or pseudopyloric metaplasia.

研究目的:

自身免疫性胃炎是一种病因不明、复杂且易被忽视的疾病。近年来随着对该疾病的认识不断更新发现其发病率被低估,其在免疫机制、诊断及治疗策略有所提高。现仍面临早期诊断率低,缺乏根治手段等调整。本研究依托厦门市健康医疗大数据中心平台资源,针对该疾病的人口统计学特征、内镜、血清学及病理特征,以及并发症评估进行分析研究,填补厦门地区A型胃炎的流行病学数据空白,揭示该地区A型胃炎的风险模式,推为临床早期诊断及干预提供依据,动区域型胃癌的防控策略优化,有望为区域性疾病防控提供科学依据,最终实现疾病的早发现、早期干预及个体化治疗,助力“健康厦门”战略实施。  

Objectives of Study:

Autoimmune gastritis is a disease of unknown cause, complex in nature, and often easily overlooked. In recent years, with the continuous updating of understanding about this disease, it has been found that its incidence was underestimated, and there have been improvements in understanding its immune mechanisms, diagnosis, and treatment strategies. However, challenges such as low early diagnosis rates and the lack of curative methods still remain. This study utilizes the resources of the Xiamen Health and Medical Big Data Center platform to analyze the demographic characteristics, endoscopic, serological, and pathological features, as well as complication assessments of this disease. It aims to fill the epidemiological data gap of type A gastritis in the Xiamen area, reveal the risk patterns of type A gastritis in this region, and provide a basis for early clinical diagnosis and intervention. Additionally, it seeks to optimize prevention and control strategies for region-specific gastric cancer, offering a scientific basis for regional disease prevention, ultimately achieving early detection, early intervention, and individualized treatment, thereby supporting the implementation of the 'Healthy Xiamen' strategy.
