局部胆囊炎,与免疫球蛋白G4 (IgG4) 相关的胆囊炎,呈现出亚皮质病变. 这种罕见的疾病,通常涉及腺肌瘤病,对葡萄糖皮质激素治疗有积极的反应.
科学领域:
- 胃肠病学 胃肠病学
- 免疫学 免疫学 免疫学
- 病理学 病理学 病理学
背景情况:
- 与免疫球蛋白G4 (IgG4) 相关的胆囊炎是影响胆囊的IgG4相关疾病 (IgG4-RD) 的表现.
- 局部IgG4相关胆囊炎不常见,并未得到充分了解.
- 在日本进行了一项全国性的多中心研究,以确定其临床病理学特征.
研究的目的:
- 为了澄清局部型IgG4相关胆囊炎的临床病理特征.
- 描述成像和组织病理学发现的特征.
- 为了评估治疗反应.
主要方法:
- 收集了从疑似病例中收集的临床数据,成像和组织幻灯片,供中央审查.
- 评估了15名被诊断患者的临床病理学特征.
- 评估了手术和葡萄糖皮质激素治疗的治疗结果.
主要成果:
- 15名患者被诊断出局部IgG4相关胆囊炎 (0.59%的IgG4-RD胃肠道疾病).
- 所有患者血清IgG4和其他IgG4-RD病变的升高;成像显示了亚皮质病变 (SELs),通常伴有腺瘤 (ADM).
- 组织病理学揭示了大量形成的病变 (炎症性伪瘤) 与史托里形纤维化和消灭性炎; 葡萄糖皮质激素治疗在响应者中显示部分到完全的解决.
结论:
- 局部IgG4相关胆囊炎通过SELs的成像发现来确定.
- 组织病理特征与IgG4-RD一致,经常出现ADM中心的病变.
- 这种情况表明对葡萄糖皮质激素治疗的反应.

In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
