概括
高达5.5%的炎症性肠病 (IBD) 患者累积显著的辐射暴露,达到75mSv的累积有效剂量 (CED). 虽然大多数成像是合适的,但最小化辐射对于IBD患者的护理至关重要.
科学领域:
- 医疗成像医学成像
- 放射学 放射学是一门学科.
- 胃肠病学 胃肠病学
背景情况:
- 放射性成像对于诊断和监测炎症性肠道疾病 (IBD) 是至关重要的.
- 由于对辐射风险的担忧,需要尽量减少暴露于"尽可能低的合理可实现"水平,理想情况下低于75mSv.
- 有限的现实数据存在于IBD患者的累积辐射暴露.
研究的目的:
- 为了追溯分析比利时第三级转诊中心IBD患者的辐射暴露.
- 确定超过75mSv的累计有效剂量 (CED) 的IBD患者的比例.
- 在IBD管理中识别导致辐射暴露的因素.
主要方法:
- 审查了4333名IBD患者的电子健康记录中的辐射暴露检查.
- 计算年有效剂量 (AED) 和累计有效剂量 (CED).
- 对2007年1月1日之后诊断的患者进行了分分析,对这些患者的详细剂量数据被前性地保持.
主要成果:
- 中位数AED为0.47mSv/年,在克罗恩氏病 (CD) 中高于性结肠炎 (UC).
- 5.5%的患者在24年的中位随访后达到CED≥75mSv.
- 在2007年以后诊断的患者中,3.3%的患者在9年后达到CED≥75mSv;像恶性瘤这样的并发症是暴露的常见原因.
结论:
- 显著的百分比的IBD患者可能超过推的累积辐射剂量.
- 虽然大多数成像是合适的,但需要持续保持警,以管理辐射暴露.
- 对优化IBD患者成像策略的进一步研究是有必要的.

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
93
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

01:21Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
83
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
