Special Issue Information

Dear Colleagues,

Asthma is a widespread, chronic airway condition that affects between 1% and 18% of the population across different countries. The prevalence of severe asthma is estimated to be approximately 3–10% of individuals with asthma, in whom the disease cannot be adequately controlled despite adherence to optimized high-dose ICS-LABA therapy and addressing contributing factors, or else the condition worsens when the treatment dose is reduced.

Managing severe asthma places a significant strain on healthcare systems and typically requires referral to specialized centers. From the patient's perspective, there is a considerable negative impact on quality of life due to persistent symptoms despite high-dose inhaled treatment, unexpected flare-ups, and medication side effects. Additionally, severe asthma can disrupt family, social, and work life, as well as affect emotional and mental well-being.

In recent years, advancements in understanding the underlying mechanisms of severe asthma and the introduction of biologic therapies have led to significant progress in managing the condition. Phenotyping severe asthma patients has become routine practice, enabling the use of targeted therapies. Clinical experience with these new treatments gradually accumulates; however, several important questions about long-term safety, treatment duration, optimal administration frequency, switching between agents, and adjustments to inhaled medications remain unanswered. Real-world evidence is still relatively sparse. Given the extremely high interest in this topic for both researchers and medical practitioners, Applied Sciences is launching a Special Issue entitled ‘Clinical Research on Severe Asthma: Latest Advances and Prospects’. The aim of this Special Issue is to foster both cutting-edge research reports as well as insights from clinical experience.

We are pleased to invite submissions of original articles reporting on basic and clinical research on severe asthma, as well as interesting case reports, perspectives, reviews, systematic reviews, and meta-analyses. Suggested themes for submissions:

  • Impact of comorbidities on asthma control.
  • Novel therapeutic agents.
  • Clinical remission in severe asthma.
  • Navigating between different biologic agents: when and how to switch?
  • Long term safety of biologics in severe asthma.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

(1) Background: Respiratory allergens, particularly ragweed (RW) pollen and house dust mites (HDMs), are major triggers of respiratory inflammation and allergic diseases. This study investigated the impact of single- versus combined-allergen exposure on the barrier function of normal human bronchial epithelial (NHBE) cells cultured at the air–liquid interface (ALI). (2) Methods: NHBE cells were exposed to RW pollen extract (200 µg/mL), HDM extract (200 µg/mL) and their combination at varying concentrations (200 µg/mL, 100 µg/mL, 50 µg/mL, 25 µg/mL). Additional groups included a mixture of Amb a 1, Amb a 11 and Amb a 12 (100 mg/mL) and combinations of Der p 1 with the ragweed allergens (50 mg/mL, 100 µg/mL). Transepithelial electrical resistance (TEER) was recorded over 72 hours to assess barrier integrity, and immunofluorescence (IF) staining for zonula occludens-1 (ZO-1) was performed to evaluate tight junction alterations. (3) Results: TEER measurements showed a significant reduction in epithelial barrier integrity following allergen exposure, with the most pronounced disruption observed with the combined exposure to RW and HDM groups. IF staining confirmed extensive tight junction damage, highlighting their synergistic impact. (4) Conclusions: These findings emphasize the importance of assessing cumulative allergen effects, as combined exposure may exacerbate epithelial dysfunction and represent a key aspect in the management of allergic rhinitis and asthma.
