  • Allergen immunotherapy (AIT) has been used for over a century and has been demonstrated to be effective in treating patients with various allergic diseases. AIT allergens can be administered through various routes, including subcutaneous, sublingual, intra-lymphatic, oral, or epicutaneous routes. Sublingual immunotherapy (SLIT) has recently gained clinical interest, and it is considered an alternative treatment for allergic rhinitis (AR) and asthma. This review provides an overview of the current evidence-based studies that address the use of SLIT for treating AR, including (1) mechanisms of action, (2) appropriate patient selection for SLIT, (3) the current available SLIT products in Korea, and (4) updated information on its efficacy and safety. Finally, this guideline aims to provide the clinician with practical considerations for SLIT.

  • Modified rush ASIT protocol has been performed to identify the ideal schedule that allows the dose considered effective to be reached in the shortest possible time with the fewest adverse effects. Ten atopic dogs of this study includes fulfillment of Favrot's criteria. Offending allergens were identified by the use of IDST. During the induction period, the dogs were received a total of 15 injections. Ten injections were administrated every 30 minutes in a day with gradually increasing amounts and concentrations of allergens, and the last 5 injections were administered every 3 days. Disease severity was quantified by using the canine atopic dermatitis extent and severity index (CADESI). During induction period, reduction rate from baseline scores varied between 1% and 67% and the improvement of ${\geq}50%$ was recorded after induction period of therapy for CADESI-03 score in 6 of the 10 dogs. This study of ten dogs with atopic dermatitis provide evidence for the efficacy and safety of modified rush ASIT for clinical improvement.

  • Renal cell carcinoma(RCC) is one of the major malignant renal cell tumors. Although RCC can metastasize to almost every organ, the most common metastatic sites are the lung parenchyma, the bones, the liver, and the brain. Adrenal metastasis from RCC is extremely rare. Adrenal metastasis from RCC shows poor prognosis, with little benefit from chemotherapy, radiation therapy, hormone therapy or immunotherapy. In this report, we describe a case of an RCC patient who showed lung and adrenal metastasis. The patient underwent left nephrectomy and chemotherapy(sunitinib), which were not effective. He refused further conventional medical treatment, and instead started treatment with Traditional Korean Medicine using allergen-removed Rhus verniciflua Stokes. After about 3 months of this treatment, the size of the adrenal tumor had decreased significantly with good performance status. Further study will be needed to demonstrate the tumor regression effect of allergen-removed Rhus verniciflua Stokes on patients with metastatic renal cell carcinoma.

  • Cockroaches have been recognized as a major cause of asthma. Bla g 4 is one of the most important German cockroach allergens. The aim of this study is to investigate IgE reactivity to the recombinant Bla g 4 (rBla g 4) in the sera of allergic patients and identify linear IgE binding epitope. For protein expression, full-length Bla g 4 (EF202172) was divided into 5 overlapping peptide fragments (E1: aa 1-100, E2: aa 34-77, E3: aa 74-117, E4: aa 114-156, and E5: aa 153-182). The full-length and 5 peptide fragments of Bla g 4 was generated by PCR and over-expressed in E. coli BL21 (DE3). The IgE binding reactivities of the full-length and peptide fragments were measured by ELISA using 32 serum samples of cockroach allergy. The sera of 8 patients (25%) reacted with rBla g 4. Four sera (100%) showed IgE-binding reactivity to full-length and peptide fragment 4, and 2 sera (50%) reacted with peptide fragment 2. One (20%) serum reacted with peptide fragment 3. The results of ELISA using overlapping recombinant fragments indicated that the epitope region was located at amino acid sequences 34-73 and 78-113, and major IgE epitope of Bla g 4 was located at amino acid sequences 118-152 of C-terminal. B-cell epitope analysis of German cockroach allergen Bla g 4 could contribute to the strategic development of more specific and potentially efficacious immunotherapy.

  • Purpose : Immunotherapy is accepted as the only treatment of allergic disease that can modify the natural course of the disease and ameliorate symptoms. This study aimed to evaluate the safety and efficacy of ultra-rush therapy using Dermatophagoides extracts in children. Methods : Of children older than four years who had visited Bundang CHA Pediatric Allergy Clinic, those showing positive reactions only to Dermatophagoides in the skin prick test and to the nasal provocation test were included. In all, 11 and 12 patients respectively preferred conventional and ultra-rush immunotherapy. We elevated allergen concentrations diluted to 1,000:1 of the end strength by 2-3 times with 30-minute intervals and checked oxygen saturation, pulse rate, blood pressure, and systemic reactions every 15 minutes. Immunotherapy effectiveness was valued by changes in nasal provocation test scores before and after immunotherapy. Results : The average ages of patients in the conventional and ultra-rush immunotherapy groups were $8.3{\pm}2.3$ and $9.2{\pm}2.8years$, respectively. Systemic reactions were observed in six in the ultra-rush group (50%) without anaphylaxis and one (9%) in the conventional group. The average scores in the nasal provocation test before and after treatment in the conventional group were $8.2{\pm}1.5$ and $4.6{\pm}2.1$, respectively (P=0.043). In the ultra-rush immunotherapy group, the scores changed from $6.2{\pm}2.2$ to $3.7{\pm}2.5$ (P=0.017). Conclusion : Ultra-rush immunotherapy using Dermatophagoides in children is effective for treating allergic disease but can induce systemic effects rather than conventional immunotherapy.

  • Background: The present study examines a hypothesis that short allergen-derived peptides may shift an Aspergillus fumigatus (Afu-) specific TH2 response towards a protective TH1. Five overlapping peptides (P1-P5) derived from Asp f1, a major allergen/antigen of Afu, were evaluated for prophylactic or therapeutic efficacy in BALB/c mice. Methods: To evaluate the prophylactic efficacy, peptides were intranasally administered to naive mice and challenged with Afu-allergens/antigens. For evaluation of therapeutic efficacy, the mice were sensitized with Afu-allergens/antigens followed by intranasal administration of peptides. The groups were compared for the levels of Afu-specific antibodies in sera and splenic cytokines evaluated by ELISA. Eosinophil peroxidase activity was examined in the lung cell suspensions and lung inflammation was assessed by histopathogy. Results: Peptides P1-, P2- and P3 decreased Afu-specific IgE (84.5~98.9%) and IgG antibodies (45.7~71.6%) in comparison with Afu-sensitized mice prophylactically. P1- and P2-treated ABPA mice showed decline in Afu-specific IgE (76.4~88%) and IgG antibodies (15~54%). Increased IgG2a/IgG1 and IFN-${\gamma}$/IL-4 ratios were observed. P1-P3 prophylactically and P1 therapeutically decreased IL-5 levels and eosinophil peroxidase activity. P1 decreased inflammatory cells' infiltration in lung tissue comparable to non-challenged control. Conclusion: Asp f1-derived peptide P1, prophylactically and therapeutically administered to Balb/c mice, is effective in regulating allergic response to allergens/antigens of Afu, and may be explored for immunotherapy of allergic aspergillosis in humans.

  • Cockroaches can cause allergic sensitization in humans via contact with their feces or frass. Antibiotics can affect concentration of major allergen and total bacteria production in German cockroaches (Blattella germanica). This study examined the ability of antibiotic-treated German cockroaches to induce allergic airway inflammation and the effect of antibiotics on their lipopolysaccharide and Bla g1, 2, and 5 expression levels. Specifically, we measured the ability of German cockroach extract (with or without prior antibiotic exposure) to induce allergic inflammation in human bronchial epithelial cells and a mouse model of asthma. Bacterial 16S rRNA and lipopolysaccharide levels were lower in ampicillin-treated cockroaches than in the control group. The Bla g1, Bla g2, and Bla g5 expression in ampicillin-treated cockroaches decreased at both the protein and RNA levels. In human bronchial epithelial cell lines BEAS-2B exposed to the ampicillin-treated extract, expression levels of interleukin-6 and interleukin-8 were lower than that in the control group. The total cell count and eosinophil count in bronchoalveolar lavage fluid was also lower in mice exposed to the ampicillin-treated extract than in those exposed to normal cockroach extract. Mouse lung histopathology showed reduced immune cell infiltration and mucus production in the ampicillin group. Our results showed that ampicillin treatment reduced the symbiont bacterial population and major allergen levels in German cockroaches, leading to reduced airway inflammation in mice. These results can facilitate the preparation of protein extracts for immunotherapy or diagnostics applications.

  • Allergy is one of the most common intractable disease, and also allergic rhinitis is the common symptom of the allergic diseases encountered in the otolaryngologic department. There are number of treatment such as: allergen avoidance by environmental control, pharmacotherapy, allergen immunotherapy and more. But choosing the exact reguired treatment is very difficult and troublesome. During the past 3 years, we have provided treatments to 49 allergic rhinitis patients with the combined therapy of stellate ganglion block(SGB) and eletrical acupuncture(E-AP) with very good results. From our experiences we highly recommend the combined therapy with SGB and E-AP for allergic rhinitis.
