Introduction:
Dupilumab, a fully human anti-interleukin-4/interleukin-13 monoclonal antibody, has shown efficacy in many aspects of Type-2 severe asthma management. Currently, we lack real-life studies addressing the achievment of clinical remission in patients treated with this biologic.
Materials And Methods:
We performed a prospective study enrolling 18 patients with severe asthma treated with Dupilumab. We assessed main clinical, functional and biological severe asthma features at baseline (T0) and after a 1-year course of treatment (T12). Clinical remission was defined at T12 in patients without asthma exacerbations, no oral corticosteroid (OCS) use, ACT ≥ 20 and FEV1 improvement ≥ 100 ml from baseline.
Results:
Among total population, 38.9% of patients achieved clinical remission at T12. Anti IL-4/IL-13 treatment significantly reduced asthma exacerbations and OCS use in the overall cohort, with a more pronounced ACT improvement in the remission group. Patients achieving clinical remission went through a step down of the inhalation therapy, suspending long-acting anti-muscarinics administration at T12.
Conclusions:
Treatment with anti-IL4/IL13 can induce clinical remission in patients with T2 severe asthma.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
01:20Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
