Pru P 3

Background. The use of hypoallergenic derivatives is considered beneficial to promote the safety and efficacy of allergen-specific immunotherapy. We aimed to assess the efficacy of reduced and alkylated (R/A) Pru p 3, a hypoallergenic folding variant of the major peach allergen, in subcutaneous immunotherapy (SCIT) using a murine model of peach allergy. Methods and Results. After sensitization with Pru p 3, BALB/c mice received SCIT with Pru p 3 or R/A Pru p 3 and were challenged with Pru p 3. SCIT with Pru p 3, but not with R/A Pru p 3, suppressed anaphylaxis upon the challenge significantly. SCIT with Pru p 3 did not suppress Pru p 3-specific IgE and IgG1 production, but enhanced IgG2a production. In contrast, SCIT with R/A Pru p 3 suppressed IgE and IgG1 production, but enhanced IgG2a production only moderately. The therapeutic efficacy of SCIT with Pru p 3 was associated with induction of IL-10 and IFN-γ. Conclusion. Hypoallergenic folding variant of Pru p 3 is not likely an efficacious therapeutic component in SCIT of peach allergy. The lower efficacy of R/A Pru p 3 might be attributed to poor antigenicity and/or weak stability due to its unfolded conformation.

Special Case

The prevalence of allergic diseases is increasing worldwide. It is estimated that more than 30% of the world population is now affected by one or more allergic conditions and a high proportion of this increase is in young people. The diagnosis of allergy is dependent on a history of symptoms on exposure to an allergen together with the detection of allergen-specific IgE. Accurate diagnosis of allergies opens up therapeutic options. Allergen specific immunotherapy is the only successful disease-modifying therapy for IgE-mediated allergic diseases. New therapeutic strategies have been developed or are currently under clinical trials. Besides new routes of administration, new types of allergens are being developed. The use of adjuvants may amplify the immune response towards tolerance to the antigens. In this review, we analyze different antigen-specific immunotherapies according to administration route, type of antigens and adjuvants, and we address the special case of food allergy.

Intralymphatic Immunotherapy

The only causative treatment for IgE-mediated allergies is allergen-specific immunotherapy. However, fewer than 5% of allergy patients receive immunotherapy because of its long duration and risk of allergic side effects. We aimed at enhancing s.c. immunotherapy by direct administration of allergen into s.c. lymph nodes. The objective was to evaluate safety and efficacy compared with conventional s.c. immunotherapy. In a monocentric open-label trial, 165 patients with grass pollen-induced rhinoconjunctivitis were randomized to receive either 54 s.c. injections with pollen extract over 3 years [cumulative allergen dose 4,031,540 standardized quality units (SQ-U)] or 3 intralymphatic injections over 2 months (cumulative allergen dose 3,000 SQ-U). Patients were evaluated after 4 months, 1 year, and 3 years by nasal provocation, skin prick testing, IgE measurements, and symptom scores. Three low-dose intralymphatic allergen administrations increased tolerance to nasal provocation with pollen already within 4 months (P < 0.001). Tolerance was long lasting and equivalent to that achievable after standard s.c. immunotherapy (P = 0.291 after 3 years). Intralymphatic immunotherapy ameliorated hay fever symptoms (P < 0.001), reduced skin prick test reactivity (P < 0.001), decreased specific serum IgE (P < 0.001), caused fewer adverse events than s.c. immunotherapy (P = 0.001), enhanced compliance (P < 0.001), and was less painful than venous puncture (P = 0.018). In conclusion, intralymphatic allergen administration enhanced safety and efficacy of immunotherapy and reduced treatment time from 3 years to 8 weeks.

Background: 1, 25-dihydroxy vitamin D3 (VitD3) can improve the effect of allergenspecific immunotherapy (SIT). Few data is available about its role in childhood asthma. Objective: To assess the immunological and clinical efficacy of VitD3 as an adjuvant to allergen specific immunotherapy in pediatric asthma. Methodology: Sixty nine children with atopic asthma were divided into three groups: a group received subcutaneous immunotherapy (SCIT) in combination with VitD3 (n=23), another group received SCIT alone (n=23), and the last group VitD3 alone (n=23). All children were assessed at baseline, and six months for rate of inhaled corticosteroid (ICS) discontinuation, and serum levels of IL-10, and IL-17A. Results: In the SCIT + vitD3, ICS discontinuation rate was higher compared to VitD3 alone group and SCIT alone group at the end of 6th month (P=0.555 and 0.016 respectively). The combined SCIT+ VitD3 group showed significant increase of serum IL-10 level in comparison to SCIT alone group and VitD3 alone group (P=0.000) and significant decrease in serum IL-17A level compared to VitD3 alone group (P= 0.011) Conclusion: VitD3 enhance the clinical and immunological outcomes of SIT in pediatric asthma. Further investigation is needed to evaluate this effect in a larger scale to confirm its role as an adjunct to SIT.

AbstractBackground:Allergic rhinitis is strongly associated with the presence of house dust mites. This study investigated the long-term effects of allergen-specific immunotherapy. Allergen-specific immunotherapy was applied over three years. The study was based on a 10-year follow up of patients with allergic rhinitis.Methods:The study was conducted between 2001 and 2015. Skin prick test results and symptom scores were evaluated before (26 patients) and after 3 years (20 patients) of allergen-specific immunotherapy (using data from a previously published study), and 10 years after allergen-specific immunotherapy had ended (20 of 26 patients).Results:The symptom scores before allergen-specific immunotherapy were significantly higher than those obtained after 3 years of allergen-specific immunotherapy and 10 years after allergen-specific immunotherapy (p < 0.0175). There were no significant differences between the scores obtained at 3 years and 10 years after allergen-specific immunotherapy (p > 0.0175).Conclusion:Subcutaneous immunotherapy is an effective treatment for house dust mite induced allergic rhinitis.

Background. Allergen-specific immunotherapy (ASIT) is viewed as the only treatment that influences all patho-genetically significant parts of the allergic process in the initial and late phases of the IgE-mediated allergic reaction and modifies the abnormal immune reactivity to a specific allergen. Currently, sublingual (SLIT) and subcutaneous (SCIT) immunotherapy are most commonly used in clinical practice. Despite long experience of sublingual and subcutaneous immunotherapy application, questions remain about the preferred ASIT method and comparative effectiveness of different ASIT methods. This article evaluates the efficacy, benefits of SCIT and SLIT and highlights new findings related mechanisms and potential biomarkers. The aim of the study. To evaluate the comparative efficacy of different methods of ASIT (subcutaneous and sublingual) based on clinical data and biomarkers in the blood serum and other biological fluids in adult patients with allergic rhinoconjunctivitis (with/without asthma). Materials and methods. 60 patients with allergic rhinoconjunctivitis (with/without asthma) aged 18 to 50 were randomly assigned to 3 groups treated by sublingual immunotherapy with extracts of allergens, subcutaneous immunotherapy with extracts of allergens and subcutaneous with modified allergens (allergoids) respectively. Results. The efficiency of the first course of preseason ASIT (SCIT and SLIT) with extracts of allergens and aller-goids in the control of symptoms of allergic rhinoconjunctivitis (with/without asthma) was demonstrated. After the end of the first year pre-season ASIT data analysis scales (Total Symptom Score -TSS, Medircation Score -MS) revealed the best performance in the group of patients receiving SCIT with allergoids compared with patients receiving the SLIT with extracts of allergens: the scales of the TSS (p=0.023), MS (p=0.002). In addition, at the end of the maintenance phase of ASIT in patients treated with SCIT with allergoids the level of eosinophilic cationic protein (ECP) in the nasal lavage decreased by 22% (p=0.012), secretory immunoglobulin A (sIgA) in the nasal lavage increased by 70% (p=0.001), interleukin-10 (IL-10) in serum increased by 126% (p=0.006), allergen-specific IgG4 increased by 42% (p=0.01) from the initial values, that correlates with a decrease in the severity of clinical manifestations. In pollen season ECP level in nasal lavage was significantly (p=0.007) lower in a group of patients who received SCIT with allergoids compared with patients who received the SLIT with extracts of allergens. The most significant changes of serum level of IL-10 in the pollen season occurred in a group of patients receiving SCIT with allergoids compared with patients who received SLIT (p=0.013) and SCIT (p=0.001) with extracts of allergens. Conclusion. The study results deepen the existing understanding of the mechanisms of SCIT and SLIT. They allow to develop a comprehensive assessment of the therapy efficacy scheme based on clinical parameters and on monitoring of local (ECP, sIgA) and systemic biomarkers (IL-10, allergen-specific IgG4) as well.

The purpose of this prospective, open-IV clinical trial was to assess the safety and efficacy differences between Rush immunotherapy (RIT) and conventional immunotherapy in Chinese allergic rhinitis (AR) patients. The trial involved 174 patients with AR. They were divided into two groups according to their preference of therapy: RIT or conventional immunotherapy. A total of 162 patients completed a 1-year treatment course. For safety and effectiveness evaluation, the local and systemic adverse reactions were recorded throughout the initial phase of both groups. Weeks 0, 2, 5, and 17 were set as observation time points for immunoglobulin G (IgG) and IgG4. Besides that, another observation time point (Week 11) was added in for a visual analog scale (VAS) and a weekly drug dosage scale. In the RIT group, systemic adverse events of AR were similar to those of the conventional therapy group. LTB4 was descended. The VAS of the RIT group did not show a downward trend clearly, instead Week 5 was higher compared with Week 0. The weekly drug dosage scale did not indicate a significant decline, but there was a clear rise in IgG4 in the RIT group. The safety and efficacy of RIT for AR is positive, but further study is needed for improvement.
