Part 1—allergic asthma JOURNAL=Frontiers in Allergy VOLUME=Volume 4 - 2023 YEAR=2024 URL=https://www.frontiersin.org/journals/allergy/articles/10.3389/falgy.2023.1291185 DOI=10.3389/falgy.2023.1291185 ISSN=2673-6101 ABSTRACT=Several chronic diseases only become symptomatic from the moment a certain threshold of inflammation or volume of tissue damage has been reached (1-4). By this stage the disease may be irreversible with no possibility of cure (5,6). Recently the idea of earlier pre-emptive diagnosis has evolved. For example, the concept of pre-diabetes has led to identification of likely future diabetics and provision of measures to reduce disease progression. Similarly, the pre-diagnostic phase of Alzheimer’s and Parkinson's diseases are being explored in population-based studies. In this paper we explore the possibilities for similar action in asthma.
