Introduction: Sublingual immunotherapy (SLIT) with birch pollen extract has been shown to be an efficacious treatment of allergic rhinitis (AR). An as-yet unanswered question is whether and how clinical benefit translates into patient benefit, i.e. what benefit patients derive from this treatment.Methods: This 1-year, open, prospective, multicenter, non-interventional study conducted in 75 German centers measured patient-relevant benefit of birch pollen SLIT (Staloral® Birch) using the questionnaire "Patient Benefit Index for Allergic Rhinitis (PBI-AR)". At treatment onset, patients rated the importance of 25 treatment needs; after the first birch pollen season on treatment, goal achievement was evaluated. A preference-weighted benefit index was calculated and its association with gender, asthma, allergy status, and severity of AR symptoms was determined.Results: Mean age of the 291 adult patients was 38.8 years; 58.4% were female. The most important treatment goals were to "be able to stay outdoors without symptoms" (87.3% quite or very important), "no longer have a runny or stuffed-up nose" (86.9%), and "be able to breathe through your nose more freely" (86.9%). The treatment goals with the highest benefit ratings (referring to those patients to whom the respective goal applied) were to "have confidence in the therapy" (60.5% has helped "quite" or "very much"), "have an easily applicable treatment" (55.6%), and "be able to breathe through my nose more freely" (51.7%). The average PBI-AR global score was 2.19 (SD 1.04) (0-4; with 4 indicating maximum benefit). No significant differences in PBI-AR global score or subscales were found between men and women, poly- and monoallergic patients, or patients with severe versus mild rhinoconjunctivitis. Patients with asthma reported relevant but lower benefit than patients without asthma.Conclusion: After 1 year of birch pollen SLIT treatment, patients reported considerable benefit, mainly due to a reduction of physical symptoms and treatment burden.

Introduction: Allergen immunotherapy is the only treatment option for allergic rhinitis with disease-altering potential. It was the objective of this study to assess the effectiveness and tolerability of a 5-grass pollen tablet in a large population of non-selected grass pollen allergic patients, i.e. patients with different clinical profiles in daily clinical practice.Methods: In a 2-year, prospective, open-label, multicenter, non-controlled, observational study patients were included from 327 centers across Germany. Rhinoconjunctivitis symptoms, symptomatic medication intake and adverse events were recorded.Results: A total of 1482 patients aged 4-75 years were included. During the 2-year period of 5-grass pollen tablet therapy, mean rhinoconjunctivitis score decreased significantly in the overall study population by 65.5% (P < 0.001). The percentage of patients taking symptomatic medication decreased from 83.8% to 42.7%. Mean 2-year improvements in rhinoconjunctivitis scores and decreases in the percentage of patients taking symptomatic medication were broadly similar in adults, adolescents and children, in patients with polyallergy versus monoallergy, and in patients with/without asthma. Among polyallergic patients, concomitant application of another specific immunotherapy did not impair treatment outcomes. Adverse drug reactions, predominantly affecting the local application area, occurred in 15.4% of the overall patient population (n = 229). No cases of anaphylaxis or epinephrine use were documented.Conclusion: This study indicates that sublingual immunotherapy with the 5-grass pollen tablet is well tolerated and provides sustained effectiveness over 2 years in patients with different clinical profiles, producing a significant decrease in allergic symptoms and a reduction in the use of symptomatic medication.Funding: Stallergenes GmbH.
