Summary
Accelerated immunotherapy, including cluster and rush schedules, offers faster build-up to maintenance doses. Recent studies confirm its safety across diverse patient groups and highlight immunological changes and risk factors.
Area of Science:
- Allergy and Immunology
- Immunotherapy Protocols
Background:
- Traditional immunotherapy involves slow build-up to allergen tolerance.
- Accelerated schedules, like cluster and rush immunotherapy, aim to shorten this induction phase.
Purpose of the Study:
- To provide an updated review of accelerated immunotherapy schedules.
- To synthesize recent evidence on the safety, efficacy, and immunological effects of cluster and rush immunotherapy.
Main Methods:
- Review of recent investigations and studies on accelerated immunotherapy.
- Analysis of data concerning safety in specific populations (atopic dermatitis, pediatric patients) and with allergen mixtures.
- Examination of novel allergen delivery methods (infusion pumps).
- Discussion of immunological changes and systemic reaction risk factors.
Main Results:
- Cluster immunotherapy involves sequential allergen injections over nonconsecutive days, reaching maintenance doses in 4-8 weeks.
- Rush immunotherapy administers higher doses at short intervals (15-60 min) over 1-3 days.
- Recent data support the safety of cluster schedules in atopic dermatitis, pediatric patients, and with inhalant allergen mixtures.
- Further insights into immunological alterations and systemic reaction risks associated with accelerated protocols are available.
Conclusions:
- Accelerated immunotherapy schedules (cluster and rush) are effective and safe options for allergen immunotherapy.
- Ongoing research continues to refine protocols, understand immunological responses, and minimize risks.

Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
