Study summary

The safety and efficacy of specific sublingual immunotherapy for house dust mite allergens in patients over 60 years of age with allergic rhinitis and a confirmed allergy to house dust mites were the focus of the stu First, 111 patients, ages 60-75 years, with allergic rhinitis and with a confirmed allergy to D. pteronyssinus and D. farinae by the use of skin prick tests, serum-specific IgE and nasal provocation tests were included. Patients were individually randomised to groups: active or placebo using a double-blind method. A total of 51 subjects in the sublingual allergen-specific immunotherapy (SLIT) group (Staloral 300R, Stallergens, France) and 57 in the placebo group were monitored for three years. The patients had to record on a diary card whenever they used anti-allergic medications.

Inclusion criteria

  • Subjects with allergic rhinitis who fulfilled the ARIA criterion and had a positive skin prick test (SPT), were positive for specific immunoglobulin E (sIgE) and had positive nasal provocation tests (NPTs) by Dermatophagoides pteronyssinus (Der p) and Dermatophagoides farinae (Der f) were included in the study

Exclusion criteria

Exclusion Criteria:

  • Patients with any of the following characteristics were excluded:

Interventions

  • Drugimmunotherapy Staloral

    Staloral (R) 300 is a sublingual solution of allergen extracts for allergen immunotherapy. During a 16 day incrementally increasing dose period, patients took daily increasing doses period, patients took 1-8 drops of the 100 IR/ml extract during the first 8 days. Then, on days 9-16, patients took 1-8 drops of the 300 IR/ml extract. Next, patients received maintenance treatment consisting of five applications of eight drops (equivalent to 0.5 mL) of 300 IR/mL extract five times a week. The mean duration of the treatment was 28.2 months (range: 3-36 months).

What researchers measure

Primary outcomes

  1. Number of participants with adverse event during immunotherapy

    Safety assessment of sublingual immunotherapy on the basis of the monitoring clinical adverse events during treatment by the use of a patient diary and medical examination.

    Time frame: three year

Secondary outcomes

  1. Change from baseline of nasal symptoms after immunotherapy

    Assessment of reducing the need for symptom-targeted drugs, primarily antihistamines and reducing of nasal symptoms during treatment in study patients (diary monitoring).

    Time frame: three year
