Research Status of Anemia Associated with Inflammatory Bowel Disease

炎症性肠病(IBD)是一类慢性胃肠道炎症性疾病，包括溃疡性结肠炎(UC)和罗恩病(CD)，IBD并不局限于胃肠道，还可以累及全身多个系统，在全球范围内其发病率及患病率逐年上升。贫血是IBD患者一种常见且严重的并发症。IBD相关贫血的病因多种多样，其中最常见的类型是缺铁性贫血(IDA)、慢性病贫血(ACD)是IBD。IBD相关贫血的严重程度及治疗会影响患者的生活质量及疾病转归。本文从IBD相关贫血的类型、发病机制及治疗等方面作一综述。Inflammatory bowel disease (IBD) refers to a group of chronic inflammatory disorders of the gastrointestinal tract, encompassing ulcerative colitis (UC) and Crohn’s disease (CD). IBD is not merely restricted to the gastrointestinal system; rather, it can involve multiple systemic organs. Globally, both the incidence and prevalence of IBD have been on the rise in recent years. Anemia is a prevalent and severe complication among patients with IBD. The etiologies of IBD-related anemia are multifaceted. Among them, the most common types are iron deficiency anemia (IDA) and anemia of chronic disease (ACD) associated with IBD. The severity of IBD-related anemia and its treatment strategies significantly impact the quality of life and disease prognosis of patients. This article aims to comprehensively review various aspects of IBD-related anemia, including its types, pathogenesis, and treatment modalities.
