Long-term effects of allergen-specific subcutaneous immunotherapy for house dust mite induced allergic rhinitis

A novel dose-adjustment protocol for interrupted subcutaneous immunotherapy for allergic rhinitis

Background: This study aimed to develop a novel dose strategy for subcutaneous immunotherapy to reduce medical waste and financial burdens for patients who are required to restart subcutaneous immunotherapy. Patients & methods: A prospective, nonrandomized concurrent controlled trial was performed to assess the safety and advantages of the novel dose-adjustment protocol compared with the conventional one. 76 subjects were grouped to receive novel or conventional dose-adjustment protocols. Results: The injections, visits and time needed to reach the pre-established dose with the novel regimen were decreased. Furthermore, there were no differences in side reactions between the two groups. Conclusion: The novel protocol seemed safe and well tolerated, offering the advantages of time efficiency and reduced healthcare costs.
