BackgroundThe diagnostic and therapeutic approach to grass pollen allergy is now possible by detecting specific IgE (sIgE) to its allergenic components.AimTo evaluate the correlation between the sensitisation to different molecular Phleum pratense (Phl p) allergens and clinical efficacy of SLIT.MethodsThe pilot study included 36 patients affected by allergic rhinoconjunctivitis, all treated with SLIT actively. We performed serum analysis of sIgE to Phl p 1, 2, 4, 5, 6, 7, 11 and 12. The Average Rhinoconjunctivitis Total Symptom Score (ARTSS) and the Average Combined Score (ACS) were evaluated before and after one year of immunotherapy.ResultsThree different groups of sensitisation were defined based on the range of IgE reactivity to Phleum pratense allergens at baseline: group I (sIgE reactive to 1–3 allergens); group II (sIgE reactive to 4–5 allergens); and group III (sIgE reactive to 6–8 allergens). At T0 ACS was 1.79±0.18 in group I; 1.81±0.23 in group II; and 1.95±0.34 in group III. At T1 ACS was 0.85±0.55 in group I; 1.01±0.31 in group II; and 1.44±0.39 in group III. At T1 there was a significant improvement of ARTSS and ACS for group I (p=0.001).ConclusionsSublingual immunotherapy with a grass pollen is efficacious irrespective of the patients' baseline sensitisation to either single or multiple grass pollen molecular allergens. We found that patients with few sensitisations have a greater improvement in combined symptom and medication score. SLIT improves the clinical course of allergic patients although new sensitisations may appear.
