Journal Article Summary
The article investigates the effects of montelukast, a medication used to treat allergic rhinitis, on skin prick test (SPT) reactions in patients who are sensitized to perennial allergens. This topic is significant because SPTs are essential for diagnosing allergies and determining appropriate treatments. There has been concern that long-term use of montelukast might suppress the skin's reaction to allergens, potentially affecting the accuracy of these tests. Understanding how montelukast interacts with skin responses is crucial for clinicians when preparing patients for allergy testing.
The study involved 40 patients with a history of allergic rhinitis who were treated for 32 weeks in a randomized, double-blind, placebo-controlled trial. Participants were divided into two groups, receiving either levocetirizine or desloratadine, both with and without montelukast, or a placebo. The results showed that while antihistamines effectively reduced wheal and flare sizes in SPTs, montelukast alone did not significantly change the size of wheals for allergens like histamine or house dust mites. However, it did slightly reduce flare sizes in some cases, but not enough to affect the overall results of the tests.
The study has limitations, including a small sample size and the specific population studied, which may not represent all patients with allergic rhinitis. It is important for patients to discuss their medication use, including montelukast, with healthcare professionals before undergoing allergy testing. While the findings suggest that montelukast does not need to be discontinued prior to SPTs, individual responses can vary, and healthcare providers can offer personalized advice based on a patient's medical history and treatment plan.
