Abstract

Background Subcutaneous allergen-specific immunotherapy is an effective treatment of IgE-mediated allergies, but it requires repeated allergen injections with a risk of systemic allergic reactions. Transcutaneous immunotherapy may improve patient compliance and safety.Objective To assess the safety and efficacy of epicutaneous allergen immunotherapy.Methods This monocentric, placebo-controlled, double-blind trial was conducted from March 2006 to December 2007 at the University Hospital Zurich. Thirty-seven adult patients with positive skin prick and nasal provocation tests to grass pollen were randomized to receive patches containing either allergen (n = 21) or placebo (n = 16). Treatment took place before and during the pollen season 2006, and follow-up visits took place before (n = 26) and after the pollen season 2007 (n = 30). The primary outcome measures were nasal provocation tests.Results Allergen-treated patients showed significantly decreased scores in nasal provocation tests in the first (P < .001) and second year (P = .003) after treatment. In contrast, placebo-treated patients had decreased scores in the first treatment year, 2006 (P = .03), but the effect diminished in the second year (P = .53). Although improvement of nasal provocation test scores was not significantly better in the verum versus placebo group, the overall treatment success was rated significantly higher by the allergen-treated group than by the placebo group (2006, P = .02; 2007, P = .005). No severe adverse events were observed. Occurrence of eczema after allergen patch applications proved stimulation of specific T-cell responses, but was noted as an adverse effect of the treatment.Conclusion Epicutaneous allergen immunotherapy is a promising strategy to treat allergies and merits further investigation.

  • In that trial, placebo-treated patients' nasal challenge scores decreased after year 1 (p = 0.03) but the effect diminished in year 2 (p = 0.53).

    “In placebo-treated patients, scores decreased after year 1 (p = 0.03), but the effect diminished in year 2 (p = 0.53).”
  • In a single-center, placebo-controlled, double-blind trial of 37 adults with positive SPT and nasal challenge to grass pollen, nasal challenge test scores significantly decreased in grass immunotherapy-treated patients in the first year (p < 0.001) and second year (p = 0.003).

    “In grass immunotherapy-treated patients, nasal challenge test scores significantly decreased in the first (p < 0.001) and second year (p = 0.003).”
  • In that trial, improvement of nasal provocation test scores was not significantly better in treatment vs placebo groups.

    “However, the improvement of nasal provocation test scores was not significantly better in the treatment vs placebo groups.”
  • In that trial, eczema at the application site was significantly higher in the treatment arm, and there were no serious adverse events.

    “Eczema at the application site was significantly higher in the treatment arm, and there were no serious adverse events.”
  • In that trial, patients in the treatment arm had improvement in subjective symptom scores after the 2006 (p = 0.02) and 2007 (p = 0.005) pollen seasons.

    “Patients in the treatment arm had improvement in subjective symptom scores, both after the pollen seasons of 2006 (p = 0.02) and 2007 (p = 0.005).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
