背景情况:
- 非乳性小麦敏感性 (NCWS) 涉及由小麦摄入引发的症状,与乳性疾病或小麦过敏不同.
- 确定负责NCWS的特定小麦成分仍然是一个挑战,各种化合物被认为是触发因素.
- 现有的研究缺乏关于NCWS背后的病因因素的共识.
研究的目的:

主要方法:
- 对多个文献数据库进行了全面的文献搜索,重点是初级研究研究.
- 对收集的数据进行了系统分析,以综合发现.
- 研究发现了各种研究的方法限制和不一致性.
主要成果:
- 确定了175个独特的引用,突出显示了质,可发酵碳水化合物和氨酸/氨酸抑制剂 (ATI) 作为常见的可疑触发因素.
- 16项双盲安慰剂对照研究显示质的作用结果不一致,其中8项报告了更大的症状反应.
- 对于可发酵碳水化合物 (非小麦衍生) 的证据有限,没有研究评估了ATI,在文献中指出了重要的方法缺陷.
结论:
- 质是NCWS最受研究的触发因素,但证据不一致,并受到研究设计缺陷的限制.

Allergic Reactions
Overview
Allergic Drug Reactions
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...
Hypersensitivities
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
