Combinations of clinical features aligned to the manifestations of IEI, laboratory markers, functional studies, IEI experienced histological assessment, and genetic studies, alongside recognition of atypical responses to therapy for autoimmune and inflammatory features of IEI, and atypical features of the malignancy and its response to therapy and recurrence, can help unmask the IEI hidden within SID.

It neutralizes thymic stromal lymphopoietin (TSLP). Phase 2 and phase 3 studies showed a significant reduction in asthma exacerbations in the severe asthma population, with the greatest effects seen in patients with a type 2 (T2) phenotype. TSLP is in close relation with the epithelium which is believed to be the starting point of the inflammatory cascade. Hence, blocking TSLP is expected to fully control type 2 inflammation and its actors such as interleukin 4 (IL-4), IL-13, IL-5 and eosinophils. This case report describes asthma patient cases with uncontrolled T2 inflammation on tezepelumab and explores the potential evasion mechanisms of TSLP blockage. CASES PRESENTATION: We report four patients who developed symptomatic uncontrolled T2 inflammation following the initiation to tezepelumab. All cases were biologic-experienced and achieved best asthma control with benralizumab. Several hypotheses have been proposed to explain this phenomenon. One possibility is an immune-driven process within the spectrum of eosinophilic granulomatosis with polyangiitis (EGPA). In EGPA, eosinophils act as immunoregulatory cells and have a critical role in promoting the T2 response, which truly sanction the disease as an eosinophilic immune dysfunction disorder. With such process, targeting upstream signals, such as TSLP may prove ineffective in controlling the self-sustained eosinophilic process. Additionally, local airway immunity, even in the absence of EGPA, could influence the suboptimal response to anti-TSLP therapy by exacerbating the in situ T2 response. CONCLUSION: Tezepelumab is not the optimal treatment for all asthma patients requiring biologic therapy. A non-epithelial derived source of inflammation might explain the suboptimal response. These cases stress the importance of phenotyping and individualisation of therapy as essential steps of the severe asthma care. </p>","PeriodicalId":51302,"journal":{"name":"Allergy Asthma and Clinical Immunology","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13255355/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147788455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OBJECTIVES: To systematically evaluate asthma control and exacerbation risk following SARS-CoV-2 infection in the post-acute COVID-19 phase among pediatric and adult populations. METHODS: We conducted a systematic review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines and a prospectively registered PROSPERO protocol (CRD420261290371). PubMed, Embase, CINAHL, Scopus, and Web of Science were searched from 1 January 2020 to 21 January 2026. Observational studies evaluating asthma control or exacerbation outcomes assessed ≥ 4 weeks after confirmed SARS-CoV-2 infection were included. Comparators comprised uninfected asthma controls, within-individual pre–post analyses, or population-level controls. Data were synthesised narratively due to substantial clinical and methodological heterogeneity. RESULTS: Eleven observational studies involving children and adults with asthma met the eligibility criteria. Evidence regarding post-acute asthma control was heterogeneous. Several studies reported short-term worsening of asthma control following SARS-CoV-2 infection, particularly within the first one to three months, whereas larger longitudinal and registry-based studies generally demonstrated stability or recovery of asthma control over longer follow-up. In contrast, asthma exacerbation risk showed a more consistent pattern, with large population-based studies demonstrating approximately a two- to five-fold increase in post-acute exacerbation risk among individuals hospitalised with COVID-19 (adjusted hazard ratios ranging from 2.78 to 5.12), while risk was lower and more variable among non-hospitalised cases (hazard ratios approximately 1.8–2.1). Findings were more variable and often null among patients with mild infection. No consistent evidence of sustained deterioration in asthma control was observed across longer-term follow-up. CONCLUSION: Post-acute asthma outcomes following SARS-CoV-2 infection are heterogeneous and appear to vary according to acute COVID-19 severity, follow-up duration, and study design. While transient worsening of asthma control may occur, particularly after more severe infection, the available evidence does not consistently demonstrate sustained deterioration in asthma control. These findings suggest that post-COVID asthma management may benefit from consideration of infection severity, while highlighting the need for high-quality longitudinal research to better define long-term outcomes. </p>","PeriodicalId":51302,"journal":{"name":"Allergy Asthma and Clinical Immunology","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13220527/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147693824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
