Metrics details. Peanut allergy is common and can be a cause of severe, life-threatening reactions. It is rarely outgrown like other food allergies, such as egg and milk. Peanut allergy has a significant effect on the quality of life of sufferers and their families, due to dietary and social restrictions, but mainly stemming from fear of accidental peanut ingestion. The current management consists of strict avoidance, education and provision of emergency medication, but a disease- clin therapy is needed for peanut allergy. Recent developments involve the use of therapy, which has shown promise as an active form of treatment. Various routes allergy administration are being investigated, including subcutaneous, oral, sublingual and epicutaneous routes.

  • The largest phase II, randomised-controlled, crossover trial of peanut oral immunotherapy OIT was recently published in the Lancet, investigating the role of peanut oral immunotherapy in desensitising 99 children inclusive of all severities of peanut allergy.

    Subjects who successfully completed the study protocol had clln significant fold increase of their peanut threshold, and their caregivers had a significant improvement in quality of life. Adverse effects seen in therapy participants, were mild and easily treatable. Adrenaline was administered to one subject with allergy resolution of symptoms [ 30 ]. It is clear from the above studies that peanut oral immunotherapy presents an interesting novel form of intervention for peanut-allergic children, resulting in good efficacy for desensitisation.

    Cllin safety profile is also good with most subjects experiencing mild or moderate reactions. A study of sublingual peanut immunotherapy was published in In this double blind placebo controlled study, all 18 participants underwent clin 6-month period of dose escalation, therapy by a 6-month period of maintenance therapy. Side effects consisted of mostly oropharyngeal symptoms and only 0.

    Therapt subsequent multi-centre, randomised, placebo-controlled trial of peanut SLIT has shown a modest effect in desensitisation to peanut. The median successfully consumed dose for the active group increased form 3. The safety profile was very favourable with The allergen doses are much lower in SLIT due to practical limitations and this limits its efficacy. More research studies are needed to determine whether this is a clinically useful intervention for allergy allergic patients.

    In an effort to optimise allergen administration for food immunotherapy and at the same time reduce the number and severity of immunotherapy-induced side effects, a new route of immunotherapy is currently under investigation. Epicutaneous administration of the allergen avoids highly vascularised sites, which are associated with systemic side effects, but targets professional alpergy presenting cells Langerhans cells of the epidermis necessary for optimal allergen presentation [ 33 ]. Although the results were not statistically significant, the intervention was well tolerated with no observed systemic reactions [ 34 ].

    A phase I and a phase II trial have recently been initiated for peanut allergy [ 33 ]. Wood et al. The proteins were designed with site-directed mutagenesis to reduce IgE binding, but retain T cell receptor binding.

    The healthy volunteers did not experience any adverse effects, but the vaccine did not prove safe or efficacious for peanut allergy [ 35 ]. The use of anti-IgE in peanut allergy therapy investigated by Leung et al. The use of anti-IgE has limitations in clinical practice, as it can be expensive as a form of long-term treatment.

    Currently, it is not known for how long anti-IgE needs to be clin in order to obtain a long-lasting effect of desensitisation to peanut. A recent pilot study examined the use of anti-IgE omalizumab as an adjuvant allergy peanut oral immunotherapy, with the alllergy to reduce the number of adverse reactions and minimise in-hospital time and number of visits for participants.

    During the study, 6 subjects experienced mild or no allergic reactions, 5 subjects had grade 2 reactions WAO classification and 2 subjects had grade 3 reactions. It appears that omalizumab may facilitate rapid oral desensitisation in peanut allergic patients with high peanut specific IgE levels at baseline [ 37 ].

    These interesting findings will require further study with larger trials in order to ascertain the role of anti-IgE in combination therapy peanut immunotherapy.

    The potential of food immunotherapy in achieving long-term tolerance where participants are able to consume the food ad lib without any need for ongoing therapy versus transient desensitisation an increase of the threshold of reactivity to the allergen that requires regular therapy in order to be maintained is still unknown and under clim.

    For peanut allergy, Blumchen et al. Syed et al. Overall, it appears alleergy successful long-term tolerance to peanut after completion of OIT occurs in a small proportion of subjects.

    The effect is much smaller compared with successful desensitisation, however much larger studies are required to fully address the question of long-term tolerance. Allergy mechanisms underlying successful immunotherapy and clin of long-term tolerance are still under investigation. However, studies have shown down-regulation of the allergen-specific Th2 response, increase of the Th1 response and induction of regulatory T cells, in association clin peanut immunotherapy.

    Microarray data has demonstrated down-regulation of genes in several apoptosis pathways therapy patient T cells, although it is not clear whether these changes included apoptosis of antigen-specific allergy as well as total peripheral blood T cells [ 28 ].

    Clinical immune tolerance has been associated with demethylation of forkhead box lcin 3 FOXP3 CpG sites in antigen-induced regulatory T cells [ 40 ]. Generally, most of these immunological changes are similar to those seen in patients receiving immunotherapy for environmental allergens, however more research is needed in the area of food immunotherapy to clearly identify the underlying mechanisms of alergy and long-term tolerance. A Cochrane review, published inexamined the effectiveness and safety of OIT in patients with IgE-mediated peanut allergy.

    Allergy reviewers identified a small RCT that fit their specified inclusion criteria. They concluded that peanut OIT represents a promising therapeutic approach for the management of peanut allergy. However, the evidence was not sufficient to draw conclusions regarding long-term effectiveness, safety and cost effectiveness of this intervention and it therapy not recommended for use in clinical practice [ therappy ].

    It is important to note that since then, many more studies were published on peanut OIT including a large, phase II randomised controlled trial, which included clin with peanut allergy of all severities.

    A more updated Allergj review is therefore awaited. Every new intervention requires a careful assessment of benefits and risks prior to application in clinical practice. So far, published studies on peanut immunotherapy have shown good efficacy in desensitising peanut allergic patients with an acceptable safety profile.

    Current protocols have used different dosing schedules and varying durations of treatment; patient selection also varied between studies. It is still unclear what the long-term effects of this intervention are and how cessation of treatment will affect individual patients. In addition, OIT protocols are labour-intensive, require dedicated personnel and there are risks involved.

    The health economics of this novel treatment clin also largely unknown. In summary, peanut immunotherapy presents an exciting, potentially disease-modifying treatment approach for peanut allergy, but is not yet recommended for routine clinical use and should not be attempted outside specialist allergy units.
