Asthmatics who also had a chronic bronchial condition were the most likely to have chronic rhinosinusitis (CRS) as a related condition, says a recent study by researchers from Northwestern and Johns Hopkins universities. The research analysed medical records from 1988 to 2021 on those with asthma, who had CRS and/or bronchiectasis to find that 51 percent of asthmatics who had bronchiectasis were more likely to have CRS than patients without it (36%).
