RESUMEN
Allergic respiratory diseases, such as asthma and allergic rhinitis, are global health issues and have had an increasing prevalence in the last decades. Allergen-specific immunotherapy (AIT) is the only curative treatment for allergic rhinitis and asthma, as it has a disease-modifying effect. AIT is generally administered by two routes: subcutaneous (SCIT) and sublingual immunotherapy (SLIT). Local side effects are common, but usually well-tolerated and self-limited. However, systemic side effects are rare, and associated with uncontrolled asthma and bronchial obstruction, or related to errors in administration. Physicians should constantly assess potential risk factors for not only reporting systemic reactions and fatalities but also implementing other therapies to improve AIT safety. This paper highlights recent evidence on local and systemic reactions related to SCIT and SLIT in children.

Although currently approved to treat severe asthma and chronic spontaneous urticaria, omalizumab has also been an effective and safe add-on treatment for other allergic diseases. Namely, omalizumab has been proposed to be used as add-on therapy in patients with allergic rhinitis and asthma and undergoing specific allergen immunotherapy (AIT). AIT is the only treatment that modifies the natural history of IgE-mediated diseases. This brief review summarizes the available evidence and controversies on the efficacy and safety of omalizumab combined with specific AIT.

Allergic diseases, such as IgE-mediated food allergy, asthma, and allergic rhinitis, are relevant health problems worldwide and show an increasing prevalence. Therapies for food allergies are food avoidance and the prompt administration of intramuscular epinephrine in anaphylaxis occurring after accidental exposure. However, allergen immunotherapy (AIT) is being investigated as a new potential tool for treating severe food allergies. Effective oral immunotherapy (OIT) and epicutaneous immunotherapy (EPIT) induce desensitization and restore immune tolerance to the causal allergen. While immediate side effects are well known, the long-term effects of food AIT are still underestimated. In this regard, eosinophilic gastrointestinal disorders (EGIDs), mainly eosinophilic esophagitis, have been reported as putative complications of OIT for food allergy and sublingual immunotherapy (SLIT) for allergic asthma and rhinitis. Fortunately, these complications are usually reversible and the patient recovers after AIT discontinuation. This review summarizes current knowledge on the possible causative link between eosinophilic gastrointestinal disorders and AIT, highlighting recent evidence and controversies.

Atopic dermatitis (AD) is a chronic remitting-relapsing inflammatory skin disorder. Due to the multifactorial pathogenesis, there are numerous therapeutic management approaches, mainly based on symptomatic treatments. In recent years, allergen immunotherapy (AIT) has been progressively advanced as targeted disease-modifying treatment of allergic disease. The most recent guideline from the American Academy of Dermatology concludes that data available do not support its use in AD. The Joint Task Force and The European Academy of Dermatology suggest that clinicians can consider AIT treatment in selected patients characterized by aeroallergen sensitization, prevalently HDM, severe AD, and clinical exacerbation after exposure to the causative allergen. Nevertheless, its role in AD is still under debate, especially in children.

Childhood immunisation is one of the greatest public health successes of the last century. Vaccines contain an active component (the antigen) which induces the immune response. They may also contain additional components such as preservatives, additives, adjuvants and traces of other substances. This review provides information about risks of hypersensitivity reactions to components of vaccines. Furthermore, recommendations to avoid or reduce reactions to vaccine components have been detailed.
