Why Every Asthma Patient Tells a Different Story.

Asthma has traditionally been viewed as a single disease, but recent research reveals its clinical and molecular complexity. This perspective highlights the need to shift from a traditional, uniform treatment paradigm to one that embraces the heterogeneity of asthma across individuals. Each patient presents a unique clinical story shaped by a complex interplay of genetic predispositions, developmental programming during critical early-life windows, the influence of sex and hormones, and lifelong environmental exposures.

Steady Quiet Asthma Without Biologics: One-Year Outcomes of Single-Inhaler Triple Therapy for Severe Asthma with Small Airway Dysfunction.

Small airway dysfunction (SAD) plays a critical role in the management of severe asthma, particularly in patients at risk of requiring biological therapies (BTs). Short-term studies have shown that switching to single-inhaler triple therapy (SITT) with extrafine beclomethasone-formoterol-glycopyrronium improves outcomes and helps achieve quiet asthma, a state marked by symptom control, no exacerbations or oral steroids, reduced inflammation, and better small airway function. This study investigated whether, over one year, patients could maintain this state as Steady Quiet Asthma (SQA) and whether baseline measures could predict this sustained response.

Profile of mild/moderate asthma patients: Baseline data from the MANI cohort.

Although 90% of asthmatic patients suffer from mild and moderate disease, little is known about the burden on health status and quality of life, the long-term trajectory of disease severity, and the socio-economic impact.
