The Long-Term Implications of Rhinitis and Chronic Rhinosinusitis in Young Adults

Background: The long-term impact of rhinitis and chronic rhinosinusitis (CRS) on general health and medical services utilization in young adults have been limitedly studied. Methods: A case–control study in the Israeli Defense Forces, between the years 2005 and 2019, of all individuals with either rhinitis or CRS and a matched cohort of healthy individuals with a minimum of 5 years of consecutive follow-up. Results: The study groups included 617 patients with rhinitis and 296 patients with CRS and 2739 healthy controls with an average age of 28 years. During a mean follow-up of 8 years, a significant fraction of patients in both study groups were diagnosed with asthma compared to the control group, (26.1% and 23.3% vs. 3.7%, respectively; CI 95%: 12.1%–14.9%, p < 0.0001). 7.6% of patients with rhinitis developed CRS. Significantly increased loss of productivity and medical system utilization were noted in the study groups compared to controls (p < 0.0001). Moreover, deterioration in general health, manifested as loss of physical fitness for combative service was observed in a third of patients during follow-up. Conclusions: Rhinitis and CRS significantly impact productivity and medical service utilization in young adults, as well as general health associated with development of asthma and impairment of physical fitness. A minority of rhinitis patients develop CRS overtime, further affecting this patient group. These patients should be followed up and managed to improve disease control and associated outcomes.
