Accelerated subcutaneous immunotherapy in pediatric population - Systematic review

Area of Science:

• Allergy and Immunology
• Pediatric Medicine
• Clinical Trials

Background:

• Accelerated subcutaneous immunotherapy (SCIT) provides immunotherapy benefits in a shorter timeframe than conventional SCIT.
• Respiratory allergies affect pediatric populations, necessitating effective and timely treatment options.

Purpose of the Study:

• To systematically review the clinical and immunological efficacy of accelerated SCIT build-up schedules.
• To assess the safety profile of accelerated SCIT in pediatric patients with respiratory allergy.

Main Methods:

• A systematic review of studies published between 2006 and 2015 was conducted using PubMed.
• Keywords included "immunotherapy" and "desensitization"; study selection involved title/abstract screening and full-text assessment.
• Data were qualitatively synthesized to evaluate the efficacy and safety of accelerated SCIT schedules.

Main Results:

• Eleven trials (2 rush SCIT, 9 cluster SCIT) showed accelerated schedules are clinically and immunologically efficacious, with faster effects than conventional SCIT.
• No significant differences in clinical outcomes were observed across pediatric, adult, or mixed populations.
• Most local adverse reactions were mild, with no life-threatening systemic reactions or fatal events reported, similar to control groups.

Conclusions:

• Accelerated SCIT build-up schedules are effective and safe for treating pediatric respiratory allergy.
• These accelerated schedules offer a valuable alternative to conventional SCIT, achieving clinical effectiveness sooner.
