Treatment Satisfaction During Sublingual Immunotherapy with a Five-Grass Pollen Tablet for Allergic Rhinoconjunctivitis: A Prospective, Non-Interventional Study

摘要

BackgroundSublingual immunotherapy (SLIT) is a safe/well-tolerated alternative to allergen injection immunotherapy for allergic rhinoconjunctivitis (ARC). Patient adherence is essential and patient-related outcome measures including treatment satisfaction are informative/indicative of adherence. ObjectiveThe aim was to assess treatment satisfaction with five-grass pollen tablet?SLIT under real-life conditions. MethodsTreatment satisfaction among adults taking SLIT with a five-grass pollen tablet for grass pollen-related ARC was assessed with QUARTIS, a self-report questionnaire dedicated to the management of patients treated with SLIT for ARC. This 1-year prospective, non-interventional, post-authorization study was conducted in Germany between 2008 and 2010. ResultsOf the 327 patients treated with the five-grass pollen tablet, 253 completed the QUARTIS questionnaire before and during (at least one item) treatment and were included in this analysis. Between the baseline and the treatment season, significant improvements were documented in nasal and ocular symptoms, and in the impact of allergy on everyday life. At the end of the first treatment period, patients had an improved opinion of the ease of SLIT intake and a significantly improved perception of SLIT. Compliance, overall satisfaction and motivation to continue SLIT the following year were good. Physicians’ assessments showed reduced symptoms and a reduced need for symptomatic medication throughout the study. SLIT was also well tolerated. ConclusionUnder real-life conditions, five-grass pollen tablet treatment was associated with a good level of treatment satisfaction, good symptom control, a reduced need for symptomatic medication, and favourable tolerability. These facets impacted favourably on patient functioning, disposition towards this medication, and adherence.
