Abstract
The symptoms of allergic rhinitis show marked day-night changes that are likely to be under the control of the circadian clock, but the mechanism of this control is poorly understood. Because most peripheral tissues have endogenous circadian clocks, we examined the circadian rhythm of the clock gene product PERIOD2 (PER2) in the nasal mucosa of male mice using a luciferase reporter and demonstrated for the first time the phase-dependent effects of dexamethasone (DEX) on nasal PER2 rhythm in vivo and ex vivo. The phase shifts in PER2 rhythm caused by DEX were observed around the peak phase of serum glucocorticoids, suggesting that the circadian rhythm of endogenous glucocorticoids regulates the peripheral clock of the mouse nasal mucosa. From the viewpoint of circadian physiology, the best time to administer intranasal steroid treatment for allergic rhinitis would be when no phase shift is caused by DEX: in the early evening in diurnal humans.

Abstract
OBJECTIVE We have recently reported that a new regimen of short-term oral immunotherapy (OIT) with the Cry j1-galactomannan conjugate for Japanese cedar pollinosis (JCP) is effective to the improvement in the symptoms and medication use during the pollen season and relatively safe. The effect of OIT on quality of life (QOL) of JCP patients has not been assessed. Therefore, we evaluated for the first time the effect of OIT on QOL during the Japanese cedar/cypress pollen season. METHODS A prospective, randomized, open-label trial was conducted over a period of 4 months. Participants were randomly divided into two groups. The OIT and control groups comprised 23 and 24 subjects, respectively. The build-up phase was initiated 1 month before the expected pollen season. The maintenance phase was continued for 51 days during the peak of the cedar pollen season. The QOL score in the Japan Rhinoconjunctivitis Quality of Life Questionnaire (JRQLQ) No. 1 and visual analog scale (VAS) throughout the pollen season were evaluated. RESULTS Participants receiving OIT showed significant improvements in the total QOL score and VAS throughout the pollen season compared with the control group. In addition, the mean total QOL score and VAS correlated in both groups during the pollen season. CONCLUSION The new regimen of short-term OIT using the Cry j1-galactomannan conjugate results in meaningful improvements in QOL of JCP patients. Our findings suggest that short-term OIT using allergen-galactomannan conjugates, as well as sublingual and subcutaneous immunotherapy, improves QOL of patients with pollinosis. The study was registered in UMIN-CTR (UMIN000013408) as the name of "a prospective, randomized, open study of oral Cry j1-galactomannan conjugate immunotherapy for Japanese cedar pollen allergy".

Japanese Society of Allergology task force report on standardization of house dust mite allergen vaccines - secondary publication. Allergol Int 2015; 64:181-6. [PMID: 25838095 DOI: 10.1016/j.alit.2015.01.005] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2014] [Revised: 12/21/2014] [Accepted: 01/06/2015] [Indexed: 01/27/2023] Open
Abstract
BACKGROUND In the 1990s, the Japanese Society of Allergology (JSA) standardized Japanese cedar pollen allergen vaccines. In the present study, the task force for house dust mite (HDM) allergen standardization of the Committee for Allergens and Immunotherapy of JSA reports the standardization of HDM allergen vaccines in Japan. METHODS In vivo allergenic potency was determined by intradermal testing of 51 Japanese adults with positive serum specific IgE to HDM allergens. In vitro total IgE binding potency was analyzed by competition ELISA using a pooled serum, with sera obtained from 10 allergic patients. The amounts of HDM group 1 (Der 1) and group 2 major allergens in eight HDM allergen extracts were measured by sandwich ELISAs. Correlation between the in vitro total IgE binding potency and major allergen levels was analyzed. RESULTS We selected a JSA reference HDM extract and determined its in vivo allergenic potency. The in vitro total IgE binding potency significantly correlated with Der 1 content, group 2 allergen content, and their combined amount, indicating that measurement of major allergen contents can be used as a surrogate in vitro assay. CONCLUSIONS The task force determined the in vivo allergenic potency (100,000 JAU/ml) and Der 1 content (38.5 μg/ml) of the JSA reference HDM extract, selected the measurement of Der 1 content as the surrogate in vitro assay, and decided that manufacturers can label a HDM allergen extract as having a titer of 100,000 JAU/ml if it contains 22.2-66.7 μg/ml of Der 1.

Abstract
This review discussed the contribution of eosinophilic upper airway inflammation includes allergic rhinitis (AR) and chronic rhinosinusitis (CRS) to the pathophysiology and course of asthma, the representative counterpart in the lower airway. The presence of concomitant AR can affect the severity of asthma in patients who have both diseases; however, it is still debatable whether the presence of asthma affects the severity of AR. Hypersensitivity, obstruction and/or inflammation in the lower airway can be detected in patients with AR without awareness or diagnosis of asthma, and AR is known as a risk factor for the new onset of wheeze and asthma both in children and adults. Allergen immunotherapy, pharmacotherapy and surgery for AR can contribute to asthma control; however, a clear preventive effect on the new onset of asthma has been demonstrated only for immunotherapy. Pathological similarities such as epithelial shedding are also seen between asthma and CRS, especially eosinophilic CRS. Abnormal sinus findings on computed tomography are seen in the majority of asthmatic patients, and asthmatic patients with CRS show a significant impairment in Quality of Life (QOL) and pulmonary function as compared to those without CRS. Conversely, lower airway inflammation and dysfunction are seen in non-asthmatic patients with CRS. Treatments for CRS that include pharmacotherapy such as anti-leukotrienes, surgery, and aspirin desensitization show a beneficial effect on concomitant asthma. Acting as a gatekeeper of the united airways, the control of inflammation in the nose is crucial for improvement of the QOL of patients with co-existing AR/CRS and asthma.
