Rush sublingual immunotherapy in canine atopic dermatitis: a prospective pilot study

Area of Science:

• Veterinary Dermatology
• Immunotherapy
• Allergen Extracts

Background:

• Canine atopic dermatitis (CAD) is a common allergic skin disease in dogs.
• Environmental allergens are frequent triggers for CAD.
• Current treatments for CAD have limitations in efficacy and safety.

Purpose of the Study:

• To assess the effectiveness and safety of a rush sublingual immunotherapy (SLIT) protocol for treating CAD.
• To evaluate the impact of SLIT on the Canine Atopic Dermatitis Extent and Severity Index (CADESI)-4 scores.

Main Methods:

• A pilot trial involving 20 dogs with CAD treated with rush SLIT.
• A 48-hour build-up phase followed by 6 months of maintenance SLIT.
• CADESI-4 scores were assessed at baseline and after 6 months of treatment.

Main Results:

• A 38.3% reduction in CADESI-4 scores was observed after 6 months of SLIT (p<0.01).
• Significant improvement (CADESI-4 reduction >30%) was noted in 76% of dogs.
• No severe adverse effects were reported during the trial.

Conclusions:

• Rush SLIT using environmental allergen extracts demonstrated effectiveness in reducing CAD severity.
• The SLIT protocol was well-tolerated, with no severe adverse events observed.
• Rush SLIT presents a safe and effective therapeutic option for canine atopic dermatitis.
