The prevalence of allergic rhinoconjunctivitis peaks in the spring and early summer months, the time of year when most plants flower and produce pollen. Allergy assessment continues to be a cornerstone for the diagnosis of allergic rhinoconjunctivitis.
- Seasonal allergic rhinoconjunctivitis is caused by exposure to pollen and also moulds.
- Northern Hemisphere plants introduced into Australia generally produce larger quantities and more allergenic pollen than plants native to Australia.
- Patients with the condition should be asked about both seasonal and perennial allergic triggers as often both are important.
- The nasal and ocular symptoms of allergic rhinoconjunctivitis may be accompanied by systemic symptoms such as poor sleep quality, fatigue and irritability.
- Allergy assessment is the basis of diagnosis and is essential for the facilitation of immunotherapy.
- Most patients with asthma also have rhinitis, and 15 to 30% of patients with allergic rhinoconjunctivitis have concomitant asthma.
