BACKGROUND: Specific subcutaneous immunotherapy (SCIT) with house dust mite (HDM) preparation has recently been shown to improve eczema in patients with atopic dermatitis (AD). So far, there is less data regarding efficacy and safety of specific sublingual immunotherapy (SLIT) in patients with AD. STUDY AIM: To evaluate in an open non-controlled, non-randomized pilot trial the effect of SLIT with HDM allergen extracts preparation (SLITone, ALK Abellò Italy) on SCORAD in adult patients with mild-moderate AD. PATIENTS AND METHODS: 86 Subjects (53 females and 33 males) between 3 and 60 years of age with AD and IgE-proved (Class > 2) HDM sensitization were enrolled after their informed consent in the trial. Exclusion criteria were severe asthma and treatment with systemic or high potent topical corticosteroids or immunosuppressant agents. Patients were treated with SLIT (Dermatophagoides pteronyssinus and Dermatophagoides farinae extracts: SLITone, ALK-Abellò) for at least 12 months. SCORAD was evaluated at baseline and after 12 months of treatment. RESULTS: Baseline SCORAD value, mean +/- SD, was 43.3 +/- 13.7 (range 15-84). After 1 year of SLIT, mean +/- SD, SCORAD value was reduced to 23.7 +/- 13.3 (range: 0-65) (p = 0.0001; unpaired t-test vs. baseline). This was a 46% reduction in SCORAD in comparison with baseline value. A significant improvement, defined as a SCORAD reduction of > 30%, was observed in 51 out of 86 patients (59%). In 5 patients (5.8%) SCORAD values did not change at the end of the observation period. In 30 patients (35%) the SCORAD reduction after SIT was <or= 30% in comparison with baseline. Total and specific IgE serum levels were significantly (p = 0.001) reduced after SLIT. No severe adverse events were observed during the trial. CONCLUSION: In this open non-controlled trial SLIT with HDM extracts in patients with mild to moderate AD was effective in reducing the SCORAD after 1 year of SLIT treatment. In addition the treatment was very well tolerated. Treatment with SLIT, furthermore, has allowed a gradual and relevant reduction of concomitant therapies with topical corticosteroids or immunosuppressants. Present results require further controlled trials in order to confirm the potential clinical benefit of SLIT in this clinical setting.
