ABSTRACT
Asthma is a descriptive label for an obstructive, inflammatory disease in the lower airways manifesting with symptoms including breathlessness, cough, difficulty in breathing and wheezing. From a clinician's point of view, asthma symptoms can commence at any age although most asthma patients - regardless of their age of onset - seem to have had some form of airway problems during childhood. Asthma inception and related pathophysiologic processes are therefore very likely to occur early in life, further evidenced by recent lung physiologic and mechanistic research. Herein, we present state-of-the-art updates on the role of genetics and epigenetics, early viral and bacterial infections, immune response and pathophysiology as well as lifestyle and environmental exposures in asthma across the life-course. We conclude early environmental insults in genetically vulnerable individuals to induce an abnormal, pre-asthmatic airway response as key events in asthma inception and highlight disease heterogeneity - across ages - and the potential shortness of treating all patients with asthma using the same treatments. Although there are no interventions that, at present, can modify long-term outcomes, a precision-medicine approach should be implemented to optimize treatment and tailor follow-up for all patients with asthma.
