RESUMEN
RATIONALE: In recent decades, the incidence of perennial allergic rhinitis (PAR) has been increasing annually. However, some patients could not achieve adequate symptomatic relief with routine pharmacological treatment. Consequently, there exists an urgent clinical imperative for the development of safe and efficacious treatments with sustained therapeutic impact to ameliorate the symptomatic burden and enhance the quality of life. PATIENT CONCERNS: The patient was a 35-year-old woman. She had suffered moderate and severe refractory PAR for decades and failed to sustain symptom mitigation from regular treatment. DIAGNOSES: Perennial allergic rhinitis. INTERVENTIONS: The patient underwent a 4-week course of fire needle acupuncture at Neiyingxiang, administered weekly, during which all allopathic medication was discontinued. OUTCOMES: The total nasal symptoms score, total non nasal symptoms score, rhinoconjunctivitis quality of life questionnaire, and the total nasal resistance of the patient were decreased after treatment and achieved symptomatic relief. Follow-up conducted 3 months post-treatment revealed enduring symptom relief, with only sporadic nasal congestion elicited by cold stimulus. LESSONS: This case proves that, fire needle acupuncture at Neiyingxiang may be beneficial in treating moderate and severe refractory PAR patient and have a lasting effect.

Background & objectives: Allergic rhinitis (AR) is an inflammatory disease prevalent worldwide which can affect both olfaction and quality of life (QoL). The objective of the present study was to assess olfaction and QoL changes in patients with AR before and after medical therapy. Methods: Adult participants (>18 yr) with AR were recruited for this study. These patients prospectively underwent olfaction testing using the modified Connecticut Chemosensory Clinical Research Centre Test and QoL assessment using Rhinoconjunctivitis QoL Questionnaire (RQLQ) before and after standard medical therapy with topical steroids and/antihistaminics. Results: Of the 150 patients recruited, 72 per cent had intermittent AR. The symptom of hyposmia was present in 34 patients (22.7%) and was more prevalent in patients with moderate-to-severe type of AR (P<0.001). However, olfaction testing revealed hyposmia/anosmia in 44 patients (29.3%). Mean composite olfaction scores were significantly higher in patients with mild AR compared to moderate/severe AR (P=0.026). The pre-therapy mean composite olfaction score in the 34 patients with olfaction disturbances was 3.1 standard deviation (±1.06 SD). Following therapy, the mean composite olfaction score rose to 4.3 (±1.34 SD) and this change was found to be significant (P<0.001). Mean pre-therapy RQLQ scores were 2.87 (0.06-5.33) overall. Significant improvement was also found in RQLQ scores following therapy (P<0.001). Mean RQLQ scores were significantly lower in those with moderate-to-severe AR (P<0.001) as well as those with intermittent AR (P=0.004). Nine patients had persistently high RQLQ scores after medical therapy. Interpretation & conclusions: Both olfaction and QoL showed significant improvement after medical therapy in Indian adults with AR. In those patients who do not improve, other causes must be sought for the persistent symptoms.

OBJECTIVE: To evaluate the efficacy of Chinese medicine acupoint application (CMAA) combined with Western medicine for perennial allergic rhinitis (PAR) in children. METHODS: In this prospective, parallel, randomized, placebo-controlled and single-blind trial from August to September, 2017, 180 children with PAR were randomly assigned to an integrative group (CMAA and Montelukast), CMAA group (CMAA and placebo tablet), or Montelukast group (placebo CMAA and Montelukast). Participants were applied with CMAA for 6 sessions over 2 weeks, and/or Montelukast Chewable Tablet orally once daily for 12 weeks. The changes in severity of symptoms were measured by Visual Analog Scale (VAS) and rhinitis control assessment test (RCAT) at 0, 2, 4 and 12 weeks of treatment. Blood samples were collected for serum interleukin-4, interferon gamma γ and T helper type 1 (Th1)/Th2 flow cytometric analysis at the time points of 0, 4 and 12 weeks. RESULTS: Eight cases dropped out from the trial, 3 in the integrative group, 2 in the CMAA group and 3 in the Montelukast group. The VAS scores decreased significantly while the RCAT scores increased significantly in all three groups at 4 and 12 weeks compared with baseline (P<0.01 or P<0.05). The VAS scores were significantly lower while the RCAT scores were significantly higher in the integrative and CMAA groups than the Montelukast group at 2 and 4 weeks (P<0.01 or P<0.05). At 2, 4 and 12 weeks, the scores of nasal congestion, sneezing, sleep problem, and rhinitis symptom control in the integrative and CMAA groups increased significantly compared with baseline (P<0.01 or P<0.05). The least percentages of Th2 and the most alleviated Th2 shift (highest Th1/Th2) were observed in the integrative group at 12 weeks compared with the other two groups (P<0.05). CONCLUSION: The combination of CMAA with Montelukast might be more effective and appropriate than either option alone for children with PAR.

BACKGROUND: So-Cheong-Ryong-Tang (SCRT), also known as Xiao-Qing-Long-Tang or Sho-seiryo-to, is a mixed herbal formula that is used to treat allergic rhinitis, bronchitis, allergic asthma, and common cold in traditional Korean medicine. OBJECTIVE: To assess the efficacy and safety of the SCRT for the treatment of allergic rhinitis. METHODS: We conducted a double-blind, randomized, placebo-controlled, parallel-group, multicenter study of Korean adults with perennial allergic rhinitis. The trial consisted of a 4-week oral administration of SCRT or placebo, with two visits at 2-week intervals, and an 8-week follow-up period, with two visits at 4-week intervals. The primary outcome was a change in the total nasal symptoms score. The secondary outcomes included changes in the Rhinoconjunctivitis Quality of Life Questionnaire score, total serum immunoglobulin E (IgE), cytokines levels, and nasal endoscopy index. RESULTS: SCRT improved nasal symptoms and quality of life in patients with PAR after 4 weeks medication, and these effects did not last 8 weeks after the end of medication. The level of serum IgE, eosinophil counts, and cytokines did not alter after medication. Nasal endoscopy index did not show significant difference. No serious AEs and safety assessment changes were observed in this trial. CONCLUSION: SCRT is an effective and safe medication for patients with chronic, perennial, and moderate to severe AR. A clinical study with a >4-week period of medication use, and more participants for immune material test is needed to investigate the long-term efficacy of SCRT in relieving the symptoms of nasal obstruction and identifying the underlying mechanisms of action and indications for traditional Korean medicine.

BACKGROUND: Allergic rhinitis (AR) is a common allergic disease. It affects people worldwide and traditional Chinese medicine is becoming popular among AR patients because it has a definite clinical effect and there are few adverse reactions. Lung qi deficiency and cold syndrome (LQDCS) is a frequent type of AR, and the Chinese herbal medicine bimin decoction (BMD) is prescribed for it. This study compared the clinical efficacy of BMD for AR patients with LQDCS to the conventional medicine loratadine and fluticasone nasal spray. METHODS: The study was an open-label non-inferiority randomized controlled trial. A total of 108 AR patients with LQDCS aged 19 to 60 were randomly allocated in a 1:1 ratio to the BMD group or the control group by the central computer system in Beijing Hospital of Traditional Chinese Medicine from January 2017 to April 2018. In total, 98 participants completed the study (BMD group n = 51 and control group n = 47). Patients in the BMD group received BMD while those in the control group received fluticasone nasal spray and loratadine tablets for 4 weeks. The primary outcome was the change in the Total Nasal Symptom Score (TNSS) between the baseline and the end of treatment. Changes in the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), nasal resistance, and acoustic rhinometry parameters were secondary outcomes. All side effects due to the treatments were recorded. RESULTS: After the 4-week treatment, the total TNSS was significantly reduced in both groups compared to the baseline (P < 0.05). No significant between-groups differences were observed for changes in TNSS scores [- 0.298 (95% confidence interval -0.640 to 0.140)], which was within the defined non-inferiority margin. RQLQ in both groups decreased significantly (P < 0.001) from baseline, though a more obvious reduction was observed for the BMD group (P < 0.001). There were no significant differences in nasal resistance, nasal volume, or nasal minimum cross-sectional area between groups after treatment (P > 0.05). CONCLUSIONS: These findings indicate that BMD helps relieve the symptoms of perennial AR and improves rhinitis-related quality of life. Our study indicates that BMD is non-inferior to loratadine tablets and fluticasone nasal spray for AR patients with LQDCS. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ChiCTR-INR-16010063.

INTRODUCTION: So-Cheong-Ryong-Tang (SCRT) is a herbal medicine widely used in traditional medicine for treating allergic rhinitis (AR). In animal studies, SCRT has suppressed the progression of AR. The main purpose of this study is to assess the efficacy and safety of the SCRT for the treatment of perennial allergic rhinitis (PAR) and discover the underlying mechanisms resulting in anti-inflammatory effects in humans. METHODS AND ANALYSIS: We will conduct a double-blind, randomised, placebo-controlled, parallel-group, multicentre trial of Korean adults with PAR. For the study, 156 subjects with PAR will be recruited. The trial will consist of a 4-week oral administration of SCRT or placebo with two visits at 2-week intervals and an 8-week follow-up period with two visits at 4-week intervals. The primary outcome is a change in the total nasal symptoms score. The secondary outcomes include changes in the Rhinoconjunctivitis Quality of Life Questionnaire score, total serum IgE and cytokines levels. ETHICS AND DISSEMINATION: This study was approved by the Institutional Review Board at each research centre (name of each centres and approval numbers): Kyung Hee University Hospital at Gangdong (KHNMC-OH-IRB 2015-04-009), Kyung Hee University Medical Centre (KOMCIRB-160321-HRBR-011), Pusan National University Hospital (2016-004), Dongguk University Medical Centre (2016-03) and Semyung University hospital (2016-01).

BACKGROUND: About 12% of children are affected by allergic rhinoconjunctivitis (AR). Although the main symptomatic treatments are intranasal corticosteroids (INCS) (daily or on demand) and oral antihistamines, it remains unclear which treatment provides the best relief of symptoms. Therefore, this study examines whether daily use of INCS is superior to on-demand use or to oral antihistamines on demand. METHODS: A single-blinded randomized controlled trial in children (aged 6-18 years) with pollen-related AR. Patients received either INCS daily (fluticasone propionate), INCS on demand (fluticasone propionate) or oral antihistamine on demand (levocetirizine) for 3 months during the grass pollen season. A daily online symptom diary on both nose and eye symptoms was completed. The primary outcome was the percentage of symptom-free days. RESULTS: A total of 150 children were randomized. The percentage symptom-free days was in favour of INCS on demand (30%) compared with INCS daily (22%), that is 8% difference (95% CI -5 to +21%; not significant). The antihistamine on-demand group had 15% symptom-free days, that is 7% difference compared to INCS daily (95% CI -6 to +19%;, not significant). Patients in the INCS on-demand group used on average 61% less fluticasone than patients in the INCS daily group during the study period (P < 0.0001). CONCLUSIONS: This trial with three parallel treatment groups shows that INCS daily was not superior to INCS on demand or to antihistamine on demand regarding the number of symptom-free days. An on-demand INCS strategy has the advantage of a lower overall corticosteroid exposure and less costs.

BACKGROUND: Allergic rhinitis (AR) is a common disorder that can significantly affect patient quality of life. Previous studies have found that curcumin had anti-inflammatory and antioxidant effects and clinical benefits in cancer and asthma. OBJECTIVE: To determine the efficacy of curcumin in the treatment of AR and to explore the molecular mechanisms involved. METHODS: In a randomized, double-blind study, 241 patients with AR received either placebo or oral curcumin for 2 months. The therapeutic effects of curcumin were evaluated by nasal symptoms and nasal airflow resistance. In addition, the production of interferon γ, interleukin (IL) 4, IL-10, and tumor necrosis factor α from mononuclear cells and IL-8, soluble intercellular adhesion molecule, polyethylene glycol 2, and leukotriene C4 from polymorphonuclear neutrophils were compared before and after curcumin treatment. RESULTS: Curcumin alleviated nasal symptoms (sneezing and rhinorrhea) and nasal congestion through reduction of nasal airflow resistance. Curcumin was found to exert diverse immunomodulatory effects, including suppression of IL-4, IL-8, and tumor necrosis factor α and increased production of IL-10 and soluble intercellular adhesion molecule. However, curcumin did not affect the release of prostaglandin E2 and leukotriene C4 from polymorphonuclear neutrophils. CONCLUSION: This pilot study provides the first evidence of the capability of curcumin of improving nasal airflow and modulating immune response in patients with AR.

OBJECTIVE: Asthma and allergic rhinitis are chronic inflammatory diseases of the conducting nasal airway. Traditional Chinese medicine has long been used for supplemental therapy of allergic diseases, especially asthma and allergic rhinitis. We previously reported the effects of a mixed herbal formula in patients with allergic rhinitis. However, the immune-modulatory mechanism underlying the effects of herbal medicine for the treatment of allergic diseases remains unclear. METHODS: We investigated the physiologic changes in dendritic cell (DC) and CD4(+) T cell activity in patients with asthma and allergic rhinitis who were treated with a mixed herbal formula composed of Xin-yi-san + Xiao-qing-long-tang + Xiang-sha-liu- jun-zi-tang. Specifically, we set up in vitro autologous or heterologous co-culture experiments between DCs and CD4(+) T cells, and used flow cytometry and ELISA to analyze the expression of surface molecules on DCs and the release of cytokines by CD4(+) T cells. RESULTS: Expression of HLA-DR on DCs was suppressed following treatment with the mixed herbal formula. Surface expression of CD40, CD54 and CD86 on DCs was also attenuated after treatment. In autologous co-cultures, CD4(+) T cells increased their IL-10 production while decreasing TNF-α production. In heterologous co-cultures, IL-10 secretion by T cells was enhanced, while IL-12, IL-4, IL-5 and TNF-α secretion were reduced. CONCLUSION: Our mixed herbal formula attenuated the allergic reaction by modifying the physiologic function of the DC-CD4(+) T cell interaction. Further investigations are necessary to understand the mechanism of immune modification mediated by the mixed herbal formula.

OBJECTIVE: To further evaluate the efficacy and safety of a pollen blocker cream against dust-mite allergy. METHODS: A multicenter, randomized, double-blind, placebo-controlled, crossover trial was conducted in a Chinese population. Patients diagnosed with perennial allergic rhinitis, sensitive to dust-mite allergy including Dermatophagoides farinae and Dermatophagoides pteronyssinus were randomly allocated to receive a pollen blocker cream or placebo, which was applied and spread evenly to the lower internal nose region three times daily for a total of 30 days. The primary outcome measurements for efficacy were total nasal symptom score (TNSS) and individual nasal symptom score (iNSS). Adverse events were also monitored. RESULTS: After application of a pollen blocker, the mean TNSS decreased from 23.1 to 13.8, the decrease of the pollen blocker group (9.3) was highly significant compared with the placebo group (5.2; p < 0.001). Similarly, the decreases in iNSSs (rhinorrhea, congestion, sneezing, and itching) between the pollen blocker group and the placebo group were also significant (p < 0.05). In addition, in adults, the pollen blocker led to a remarkably significant decrease in TNSS (9.5) compared with placebo (5.4; p < 0.001); in children, the pollen blocker led to a significant decrease in TNSS (8.6) compared with placebo (4.8; p < 0.05). No statistical difference was found in the incidence of adverse events between the two groups (p > 0.05), and no severe systematic reactions were observed. CONCLUSION: Pollen Blocker is a safe and effective alternative to the drugs for treatment of AR, especially for Chinese people allergic to dust-mite allergy.

OBJECTIVE: To compare the efficacy differences between dog-days medicinal vesiculation and regular-day medicinal vesiculation for perennial allergic rhinitis (PAR), and observe their effects on serum immune globulin E (IgE) and interleukin-4 (IL-4). METHODS: Seventy-two patients were randomly divided into a dog-days moxibustion group (34 cases) and a regular-day moxibustion group (38 cases). In the dog-days moxibustion group, medicinal vesiculation was applied on the 1st dog-day, 2nd dog-day and last dog-day in summer by lunar calendar, 3 treatments per dog-day for totally 9 times. In the regular-day moxibustion group, the moxibustion was given on the regular day for continuous 9 times. The symptom score, rhinoconjunctivitis quality of life questionnaire (RQLQ) and the level of IgE and IL-4 were compared before and after treatment in two groups; the short-term and two-year efficacy evaluation were performed too. RESULTS: The short-term total effective rate was 88.2% (30/34) in the dog-days moxibustion group, which was not significantly different to 86.8% (33/38) in the regular-day moxibustion group (P>0.05). The long-term total effective rate was 97.1% (33/34) in the dog-days moxibustion group, which was significantly superior to 81.6% (31/38) in the regular-day moxibustion group (P<0.05). After treatment, the serum IgE, IL-4 and RQLQ were significantly reduced (all P<0.01), but the difference between two groups was not significant (all P>0.05). CONCLUSION: Medicinal moxibustion could be taken as a regular treatment for PAR, which could be performed during the whole year, and dog-days moxibustion could be considered as an enhanced method for prevention and treatment of PAR.

OBJECTIVE: To compare the efficacy of an acupuncture regimen for persistent allergic rhinitis (PER), aimed at improving a patient's mind or Shen in Traditional Chinese Medicine, to that of a second-generation Hi-receptor antagonist, cetirizine hydrochloride. METHODS: This multicenter, randomized, controlled clinical trial on PER will be conducted at three institutions in China. The total study period will be 9 weeks. After a 1-week preparatory screening period, 240 eligible participants with PER will be randomized to receive acupuncture or pharmacotherapy (1:1) for 4 weeks with a 4-week follow-up. The primary outcome will be changes in 7-day average total nasal symptom score. Secondary outcome measures include rhinoconjunctivitis quality of life questionnaire score and total non-nasal symptom score. RESULTS: The presence and seriousness of psychological and emotional impairments should be considered in therapeutic programs for allergic rhinitis. No clinical trial for treating allergic rhinitis via acupuncture regulation of psychological and emotional activities has been reported. CONCLUSION: The findings of the trial will allow us to determine the effects of the mind (Shen)-regulation treatment approach. We will also be able to confirm if the effects of acupuncture are equivalent to those of the conventional drug cetirizine hydrochloride.

A predominant Th17 population is a marker of allergic rhinitis (AR). The aryl hydrocarbon receptor (AhR) exhibits strong immunomodulation potential via regulation of the differentiation of T lymphocytes and dendritic cells (DCs) after activation by its ligand, such as 2-(1'H-indole-3'-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE). The aim of this study was to analyze the effect of AhR on Th17 differentiation by investigating the action of ITE on DCs and CD4(+) T cells from patients with AR. In all, 26 AR patients and 12 healthy controls were included in this study. The expression of interleukin (IL)-1ß, IL-6, IL-10, and IL-17 in the culture supernatant and the presence of Th17 cells in CD4(+) T cells and DC-CD4(+) T-cell co-culture system were measured before and after treatment with ITE. We show that ITE significantly induced cell secretion of IL-10 and inhibited IL-1ß and IL-6 production in DCs, and promoted IL-10 production and suppressed IL-17 expression in CD4(+) T cells in vitro. It also suppressed the expansion of Th17 cells in vitro. Our work demonstrates that ITE acts on DCs and CD4(+) T cells to inhibit the Th17 response that suppresses AR; the AhR-DC-Th17 axis may be an important pathway in the treatment of AR. ITE, a nontoxic AhR ligand, attenuated the Th17 response; thus, it appears to be a promising therapeutic candidate for suppressing the inflammatory responses associated with AR.

Because of its burden on patient's lives and its impact on asthma, allergic rhinitis must be treated properly with more effective and safer treatments. According to guidelines by Allergic Rhinitis and Its Impact on Asthma (ARIA), the classification, pathogenesis, and treatment of allergic rhinitis are well defined. Currently, second-generation antihistamines and inhaled steroids are considered the cornerstone of first-line therapy. However, new formulations of available drugs (e.g., loratadine and rupatadine oral solution, ebastine fast-dissolving tablets, and the combination of intranasal fluticasone propionate and azelastine hydrochloride), recently discovered molecules (e.g., ciclesonide, bilastine, and phosphodiesterase-4 inhibitors), immunologic targets (e.g., omalizumab), and unconventional treatments (e.g., homeopathic treatments) are currently under investigation and represent a new frontier in modern medicine and in allergic rhinitis management. The aim of this review is to provide an update on allergic rhinitis treatment, paying particular attention to clinical trials published within the past 20 months that assessed the efficacy and safety of new formulations of available drugs or new molecules.

AIMS: The (2'S,7'S)-O-(2-methylbutanoyl)-columbianetin (OMC) is a novel secondary metabolite extracted from Corydalis heterocarpa, which has long been used as a folk medicine for various inflammatory diseases in Korea. We examined the effect of OMC on allergic rhinitis (AR). MAIN METHODS: We assessed the therapeutic effects and regulatory mechanisms of OMC on the phorbol 12-myristate 13-acetate plus A23187-stimulated mast cell line, HMC-1 cells and ovalbumin (OVA)-induced AR models. KEY FINDINGS: OMC significantly decreased the releases of histamine and tryptase from stimulated HMC-1 cells. The degranulation process, characterized by morphological extension of the filopodia on the surface and membrane ruffling, was strongly induced in the stimulated-HMC-1 cell, however OMC suppressed the morphological changes in stimulated-HMC-1 cells. OMC reduced the production and mRNA expression of inflammatory cytokines. These inhibitory actions by OMC were dependent on the regulation of mitogen-activated protein kinases, nuclear factor-κB, and caspapase-1 signaling pathways. In the AR animal model, the increased rub scores and AR biomarkers (histamine and IgE) in ovalbumin (OVA)-sensitized mice were significantly reduced by the administration of OMC. Furthermore, eosinophils and mast cell infiltrations in nasal mucosa tissue were also blocked through the regulation of macrophage-inflammatory protein and intercellular adhesion molecule-1 levels. SIGNIFICANCE: OMC showed the possibility to regulate AR in activated mast cells and OVA-induced AR models. Hence, we suggest that OMC is a powerful and feasible new agent to suppress AR.

BACKGROUND: Allergic rhinitis (AR) is the most common manifestation of atopic reaction to inhaled allergens. It is a chronic inflammatory disease which may first appear at any age, but the onset is usually during childhood or adolescence. Up to date there is no curative treatment for this disorder and most of the drugs that were used for treatment only can induce symptomatic relief and some of them have side effect and can cause withdrawal symptoms. OBJECTIVE: To evaluate the therapeutic efficacy of the Nigella sativa (NS) extract as treatment approach for allergic rhinitis. PATIENTS & METHODS: A total of 68 patients with AR were included in the study, of them 19 patients were with mild symptoms, 28 patients were with moderate symptoms and 21 patients were with severe symptoms. Each group was subdivided into active and control subgroups. To prove that the patient's symptoms were allergic in nature, skin test was performed for all patients. Any individual with negative skin test was excluded. The individuals in the active group received N. sativa oil and the control group individuals received ordinary food oil in the form of nasal drops for 6 weeks. RESULTS: After the 6 weeks treatment course, 100% of the patients in the mild active group became symptoms free; while in moderate active group 68.7% became symptoms free and 25% were improved; while in severe active group 58.3% became symptoms free and 25% were improved. In addition, 92.1% of total patients in the active group demonstrated improvement in their symptoms or were symptoms free, while the corresponding value was 30.1% in the control group (P=0.000). At the end of 6 weeks of treatment with topical use, the improvement in tolerability of allergen exposure in active group became 55.2% which was significant (P=0.006) as compared with control group which was accounted for 20% at the same time. CONCLUSION: Topical application of black seed oil was effective in the treatment of allergic rhinitis, with minimal side effects.

The antiallergic effects of traditional medicines have long been studied. Traditional Korean medicine, Citrus sunki and bamboo salt, has been used for the treatment of allergic diseases in Korea. K-ALL, composed of Citrus sunki and bamboo salt, is a newly prepared prescription for allergic patients. To develop the new antiallergic agent, we examined the effects of K-ALL through in vivo and in vitro models. K-ALL and naringin (an active compound of K-ALL) significantly inhibited histamine release from rat peritoneal mast cells. This inhibitory effect of K-ALL on histamine release was higher than effects from other known histamine inhibitors such as bamboo salt, Citrus sunki or disodium cromoglycate. K-ALL significantly inhibited systemic anaphylactic shock induced by the compound 48/80 and passive cutaneous anaphylaxis induced by the IgE. K-ALL also inhibited production and mRNA expression of inflammatory cytokines induced by phorbol 12-myristate 13-acetate and the calcium ionophore A23187 on HMC-1 cells (a human mast cell line). In the ovalbumin-induced allergic rhinitis animal model, rub scores, histamine, IgE, inflammatory cytokines and inflammatory cell counts were all reduced by the oral or nasal administration of K-ALL (pre and posttreatment). These results indicate the great potential of K-ALL as an active immune modulator for the treatment of mast cell-mediated allergic diseases.

BACKGROUND: Idiopathic rhinitis (IR) is a prevalent condition for which capsaicin nasal spray is the most effective treatment. However, the mechanisms underlying IR and the therapeutic action of capsaicin remain unknown. OBJECTIVE: We sought to investigate the molecular and cellular bases of IR and the therapeutic action of capsaicin. METHODS: Fourteen patients with IR and 12 healthy control subjects (HCs) were treated with intranasal capsaicin. The therapeutic effect was assessed in patients with IR by using visual analog scale and therapeutic response evaluation scores, and nasal hyperreactivity was evaluated by means of cold dry air provocation. Nasal samples served to measure the levels of neuromediators and expression of chemosensory cation channels, protein gene product 9.5 (PGP 9.5), and the mast cell marker c-kit. The effects of capsaicin were also tested in vitro on human nasal epithelial cells and mast cells. RESULTS: Patients with IR had higher baseline transient receptor potential cation channel subfamily V, receptor 1 (TRPV1) expression in the nasal mucosa and higher concentrations of substance P (SP) in nasal secretions than HCs. Symptomatic relief was observed in 11 of 14 patients with IR after capsaicin treatment. Expression of TRPV1; transient receptor potential cation channel subfamily M, receptor 8 (TRPM8); and PGP 9.5 was only reduced in patients with IR after capsaicin treatment. Capsaicin did not alter c-KIT expression or nasal epithelial morphology in patients with IR and HCs nor did it induce apoptosis or necrosis in cultured human nasal epithelial cells and mast cells. CONCLUSION: IR features an overexpression of TRPV1 in the nasal mucosa and increased SP levels in nasal secretions. Capsaicin exerts its therapeutic action by ablating the TRPV1-SP nociceptive signaling pathway in the nasal mucosa.

In this study, we investigated the effects of Naju Jjok (Polygonum tinctorium Lour., NJJ) on interleukin (IL)-32 and thymic stromal lymphopoietin (TSLP) levels associated with allergic rhinitis (AR). Using female BALB/c mice, we created an animal model of ovalbumin (OVA)-induced AR. Prior to the callenge with OVA, the mice were administered, either nasally or orally with NJJ. In addition, we also used the eosinophilic cells line, Eol-1, stimulated with granulocytemacrophage colony-stimulation factor (GM-CSF). The mRNA and protein levels of inflammatory cytokines and markers [interleukin (IL)-32, IL-4, macrophage-inflammatory protein-2 (MIP-2), intercellular adhesion molecule-1 (ICAM-1), and cyclooxygenase-2 (COX-2)] were measured by RT-PCR and western blot analysis, respectively and serum levels were measured by ELISA. The increased levels of IL-32 in the mice with AR and in the stimulated eosinophilic cell line, Eol-1, were significantly reduced by NJJ. TSLP levels were also decreased following the oral administration of NJJ. Mice orally administered NJJ showed markedly alleviated clinical symptoms, such as a reduced number of nasal rubs, decreased spleen weight, decreased serum immunoglobulin E (IgE) levels and decreased serum histamine levels. The oral administration of NJJ significantly decreased the IL-4 levels, while increasing the interferon-γ levels in the spleen. The increased number of eosinophils and mast cells infiltrating the nasal mucosal tissue of the mice with AR were decreased following the oral administration of NJJ. NJJ effectively attenuated caspase-1 activity in the mice with AR and in the stimulated Eol-1 cells. The oral administration of NJJ significantly reduced the levels of inflammatory markers, such as MIP-2, ICAM-1 and COX-2. Furthermore, the intranasal administration of NJJ significantly reduced the early phase response to allergen exposure, such as nasal rubs, IgE production and histamine release, as well as the late phase responses, such as the expression of inflammatory markers. In conclusion, these data demonstrate that NJJ may play a regulatory role in nasal inflammation.
