Asthma — master index¶
Last curated: 2026-10-29 · status: partially audited (12 pages draft; independent audits of the October sweeps pending)
The condition in five sentences. Asthma is a heterogeneous inflammatory airway disease defined by variable respiratory symptoms and variable expiratory airflow limitation, ideally demonstrated objectively rather than inferred from symptoms alone (Rothe 2018, PMID 29614508). GBD 2021 estimated 260 million prevalent cases and 436,000 asthma deaths, with burden distributed unequally across regions (GBD 2021 Asthma Collaborators 2025, PMID 40147466). Type-2 inflammation drives many but not all cases, supporting eosinophils, FeNO and allergic phenotype as imperfect treatment guides rather than universal disease markers (Fahy 2015, PMID 25534623). ICS-containing therapy is the safety anchor; as-needed low-dose budesonide–formoterol reduces severe exacerbations compared with SABA-only treatment in mild asthma, and biologics now target IgE, IL-5/5R, IL-4Rα and TSLP in severe disease (O'Byrne 2018, PMID 29768149; Beasley 2019, PMID 31112386; Edris 2019, PMID 31395084; Menzies-Gow 2021, PMID 33979488). The frontier is true prevention/remission, non-type-2 therapy and access, while recurrent systemic-steroid exposure remains a marker of uncontrolled disease and cumulative harm (Price 2018, PMID 30214247).

Reading paths¶
| Need | Suggested path |
|---|---|
| Clinical orientation | overview → diagnosis → mild/moderate care → safety |
| Severe or uncontrolled disease | phenotypes/endotypes → biomarkers → severe asthma/biologics → trials |
| Mechanism and prevention | airway biology → genetics/environment/prevention → research frontier |
| Life-course and implementation | children → pregnancy → self-management → patient experience |

Curation state¶
The 2026-10-29 sweep (author: Grok) added seven bibliography records. Three source-checked updates (CHRONICLE eligibility-criteria analysis, SHARP comorbidity capture, COPSAC early-life PM2.5 and lung function) were written into wiki pages; an Australian community biomarker-prevalence estimate entered the statistics register. Genetics/environment and comorbidity were demoted from curated to draft. Six pages remain curated and twelve are draft. No landmark note was warranted. See the dated sweep manifest.
The 2026-10-22 sweep (author: Codex) added five bibliography records, two source-checked clinical updates (adult prediction models and preschool DIVA), a missed WHO childhood guideline, updated surveillance statistics and patient-organization material, and a trial-calendar change. See LOG.md and the dated sweep manifest.
The 2026-10-15 periodic literature sweep (author: Claude) edited nine wiki pages, which are now draft pending an independent audit by a different engine: biomarkers, diagnosis, severe asthma/biologics, trials landscape, red flags, epidemiology, exacerbations, children and patient experience. Nine further pages received only reference-metadata corrections (journal, volume and pages) verified against live PubMed records; comorbidity and mimics was then untouched. Two of those previously curated pages (genetics/environment and comorbidity) were demoted on 2026-10-29 after content edits. Before that, the condition was audited (2026-08-30): all 18 wiki pages passed an independent claim-to-citation audit, and 401 PubMed records and 19 ClinicalTrials.gov records were re-verified live. See LOG.md. The research frontier is maintained in OPEN-QUESTIONS.md.
