Chronic rhinosinusitis (CRS) and asthma often occur together. A US cohort study showed that CRS confirmed by sinus CT or 2 diagnoses significantly increased the risk of developing new asthma in the following year.

Chronic rhinosinusitis (CRS) and asthma often occur together. Although previous studies have suggested a link, there is a lack of large-scale research confirming this link. A study by Schwartz et al.* examined whether pre-existing CRS increases the risk of developing asthma within the next year. Such findings may have important clinical implications for asthma prevention.
The study used data from Geisinger, an integrated healthcare system in Pennsylvania, from 2008-2019. 926,397 people were included in the analysis. CRS was identified by 2 methods: sinus CT reports and at least 2 different CRS diagnoses. Individuals with pre-existing asthma were excluded to include only those who developed new asthma in the following year.
