Summary
NSAID-exacerbated respiratory disease (N-ERD) involves immune and epithelial dysfunction. Emerging biomarkers and inflammatory endotypes are key for diagnosing and personalizing treatment for N-ERD patients.
Area of Science:
- Immunology
- Pulmonology
- Genetics
Background:
- NSAID-exacerbated respiratory disease (N-ERD) is a chronic inflammatory condition involving asthma, nasal polyps, and NSAID reactions.
- Pathogenesis includes altered arachidonic acid metabolism, epithelial barrier defects, and diverse immune cell activation.
Purpose of the Study:
- To review current understanding of N-ERD's immune, epithelial, and lipid pathways.
- To highlight emerging biomarkers and inflammatory endotypes for diagnosis and personalized therapy.
Main Methods:
- Genomic and transcriptomic analyses revealing gene variants.
- Identification of novel biomarkers like 15-oxo-ETE and acylcarnitines.
- Inflammatory endotyping (T2-dominant, T1, T3, neutrophilic).
Main Results:
- Gene variants impact epithelial integrity and macrophage activity.
- Biomarkers offer mechanistic insights.
- N-ERD exhibits significant inflammatory heterogeneity.
- Aspirin Hypersensitivity Diagnostic Index shows promise.
Conclusions:
- Understanding N-ERD's complex pathways is crucial.
- Biomarkers and endotyping aid personalized treatment strategies.
- Biologics targeting T2 pathways are central; aspirin desensitization is for select cases.

01:25Inflammatory 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...
01:24Peptic Ulcer Disease II: Pathophysiology
Peptic ulcer disease develops when protective mechanisms of the gastrointestinal mucosa are overwhelmed by harmful factors, leading to localized erosions in the stomach or proximal duodenum. The main causes are Helicobacter pylori infection and chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs).Helicobacter pylori–Induced InjuryBacterial Adaptation and Colonization:H. pylori is a spiral, Gram-negative bacterium adapted to the acidic stomach. and transmitted through oral-oral or...
01:20Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
01:28Inflammatory Response
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
