Common variable immunodeficiency (CVID) is an immunodeficiency disorder with a high incidence of gastrointestinal (GI) manifestations and an increased risk of gastric malignancy. We report a case of a CVID with mild anemia presenting with multiple GI manifestations: gastric low-grade dysplasia (LGD), enteropathy with villous atrophy, refractory Giardia infection, nodular lymphoid hyperplasia, and inflammatory bowel-like disease. The differential diagnosis with celiac sprue could be challenging because of CVID enteropathy with villous flattening. Gastric LGD in a patient with an increased risk for gastric malignancy makes the appropriate surveillance of gastric cancer in CVID challenging.
普通可变型免疫缺陷(CVID)是一种免疫缺陷疾病,胃肠道(GI)表现发生率高,患胃恶性肿瘤风险增加。我们报告一例患有轻度贫血的CVID病例,该病例有多种胃肠道表现:胃低级别上皮内瘤变(LGD)、伴有绒毛萎缩的肠病、难治性贾第虫感染、结节性淋巴样增生以及炎症性肠病样疾病。由于CVID肠病伴有绒毛变平,与乳糜泻的鉴别诊断可能具有挑战性。胃恶性肿瘤风险增加的患者出现胃LGD使得对CVID患者进行适当的胃癌监测具有挑战性。
