Nasal irrigation with Glycyrrhiza glabra extract for treatment of allergic rhinitis - A study of in vitro, in vivo and clinical trial. JOURNAL OF ETHNOPHARMACOLOGY 2021; 275:114116. [PMID: 33857594 DOI: 10.1016/j.jep.2021.114116] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Revised: 04/03/2021] [Accepted: 04/06/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Glycyrrhiza glabra, a family of licorice and a traditional Chinese medicine with sweet taste and favorable smell, has anti-inflammatory, anti-allergic and immunomodulatory functions. AIM OF THE STUDY We developed a licorice extract (LE) by using glycyrrhiza glabra and administered it through nasal irrigation to treat allergic rhinitis (AR). MATERIALS AND METHODS LE was prepared into extract powder, and the anti-inflammatory effect of the LE was evaluated by calcium ionophore-induced activated mast cell model (in vitro). Then, local passive anaphylaxis assays were applied to investigate the anti-IgE-mediated allergic reaction of the LE in mice (in vivo). A developed LE was administered through nasal irrigation to treat AR in clinic settings. A total of 60 participants diagnosed with AR were included in this clinical trial; they were randomly assigned to three interventions: licorice nasal irrigation (LNI), corticosteroid nasal irrigation (CNI), and saline nasal irrigation (SNI). They performed nasal irrigation once a day for 1 month. Both subjective questionnaires (22-item Sino-Nasal Outcome Test [SNOT-22] and visual analog scale [VAS]) and objective examinations (acoustic rhinometry and nasal endoscopy) were used for effectiveness assessments. RESULTS All three interventions could improve SNOT-22 scores, but the effects of LNI and CNI were more significant. According to VAS scores for nasal blockage, rhinorrhea, sneezing, nasal pruritus, postnasal discharge, and olfactory disturbance, the effect of LNI was superior to those of CNI and SNI. The results of rhinometry revealed that LNI significantly improved nasal resistance. Endoscopic analysis showed that both LNI and CNI, but not SNI, could significantly improve turbinate hypertrophy. Moreover, the best procedural comfort was found for LNI, which had no side effects or complications during the trial. CONCLUSIONS LNI is a natural, safe, and innovative therapy that can effectively treat AR. Its effect is superior to those of CNI and SNI, and it has greatly improved procedural comfort.

The Nasal Obstruction Balance Index: A Novel Approach to Improving Correlation Between Unilateral Nasal Airway Measurements and Evaluating Nasal Airway Asymmetry. Laryngoscope 2021; 131:E2833-E2840. [PMID: 33949695 DOI: 10.1002/lary.29597] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 03/29/2021] [Accepted: 04/16/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVES/HYPOTHESIS Demonstrate that the Nasal Obstruction Balance Index (NOBI) model fulfils the unmet need of improving unilateral correlation between subjective and objective nasal obstruction outcome measures and identifying the more obstructed side. Improve correlation between unilateral objective nasal airway measurements (nasal inspiratory peak flow [NIPF] and acoustic rhinometry [AR]) and subjective Visual Analogue Scale for nasal obstruction (VAS-NO) scores. Improve assessment of nasal airway asymmetry by evaluating unilateral measurements both before and after the application of nasal decongestant; which the patient could better understand. NOBI represents a ratio calculated by taking the difference between left and right nasal airway measurements and divided by the maximum unilateral measurement. It is based on Poiseuille's law and aims to reduce the confounding variables which challenge nasal airway measurement. STUDY DESIGN Prospective cohort study. METHODS Forty-three controls and 34 patients with nasal obstruction underwent both unilateral and bilateral NIPF, AR and VAS-NO measurements; these were repeated after the application of nasal decongestant. The NOBI values for unilateral NIPF, AR, and VAS-NO were calculated both before and after decongestant. RESULTS The correlation between unilateral NIPF and AR measurements was enhanced considerably (r = 0.57, P < .01) when NOBI was applied. The NOBI metric significantly increased the correlation between unilateral NIPF, AR, and VAS-NO scores. Postdecongestant NOBI for NIPF and AR measurements correctly identified the more obstructed side in 82.4% and 94.1% of the deviated nasal septum (DNS) cases, respectively. CONCLUSION The NOBI model provides a better correlation between unilateral subjective and objective measurements and identifies the more obstructed side.

Abstract
OBJECTIVES/HYPOTHESIS There is a growing need to understand the underlying mechanisms of age-related olfactory dysfunction with the increasing proportion of older adults over the next 20 years. Despite the importance of olfactory cleft (OC) volumes on odorant deposition and olfactory function, little is known about age-related changes to OC volume. The goal of this study was to use automated techniques in a cross-sectional design to investigate the extent to which OC volumes vary with age and determine the spatial specificity of any age-related effects. STUDY DESIGN Retrospective cross-sectional study. METHODS Deformation-based morphometry was utilized to measure OC and sinus volumes in two independent samples of 101 (Medical University of South Carolina [MUSC] sample) and 95 (Hammersmith sample) healthy adults who underwent T1-weighted magnetic resonance imaging, with the Hammersmith sample serving as a replication sample. RESULTS The mean age of the MUSC and Hammersmith samples were 54.9 ± 17.0 years and 52.1 years ± 15.7 years, respectively. In both samples, there was a significant positive association between age and OC volume that occurred at a constant rate across the lifespan (Cohen's f2 of 0.065 in the MUSC sample and 0.110 in the Hammersmith sample). Age-associated OC volume increases occurred in conjunction with decreases in sinus volumes as well as increases in non-OC nasal cavity volumes. CONCLUSIONS In this cross-sectional study, there is an increase in OC volume with increasing age that occurs in the context of broad age-associated differences in sinonasal anatomy. Future studies should investigate the impact of age-associated differences in intranasal anatomy on nasal airflow, odorant deposition, and olfactory function.

Abstract
Abstract
Background: It is of clinical importance to examine the nasal cavity pre-operatively on surgical treatments. However, there is no simple and easy way to measure airflow in the nasal cavity. Objectives: Visualize the flow features inside the nasal cavity using computational fluid dynamics (CFD) method, and study the effect of different breathing rates on nasal function. Method: A three-dimensional nasal cavity model was reconstructed based on computed tomographic images of a healthy Malaysian adult nose. Navier-Stokes and continuity equations for steady airflow were solved numerically to examine the inspiratory nasal flow. Results: The flow resistance obtained varied from 0.026 to 0.124 Pa.s/mL at flow-rate from 7.5 L/min to 40 L/min. Flow rates by breathing had significant influence on airflow velocity and wall shear-stress in the vestibule and nasal valve region. Conclusion: Airflow simulations based on CFD is most useful for better understanding of flow phenomenon inside the nasal cavity.

Abstract
Background Odiosoft-Rhino (OR) is new software and equipment that can be used to measure changes in nasal obstruction after intranasal steroid treatment. OR is a promising method for measuring the degree of nasal obstruction. OR can precisely analyze nasal sound spectra in decibels, which is generated by nasal airflow. We studied the reliability of OR for assessing declining nasal obstruction after budesonide nasal spray treatment. Methods Sixty-five patients with perennial allergic rhinitis (PAR) were enrolled in the study, and 52 of these patients completed the study. Nasal endoscopic examination, acoustic rhinometry (AR), and OR were performed and symptom scores were compared before and after 3 months of treatment with intranasal budesonide. All of the patients received 7 days of placebo treatment before receiving budesonide. Results There was a significant difference in the visual analog scores of nasal obstruction and in the examination scores before and after the treatment for both the right and the left nasal cavities. Pretreatment AR findings and OR findings in the 2000- to 4000-Hz and 4000-to 6000-Hz intervals for both sides were significantly different from the posttreatment measurements (p = 0.000). Both AR and OR can assess the efficacy of budesonide nasal spray treatment for nasal obstruction in patients with PAR. Conclusion Both AR and OR are effective for assessing nasal obstruction and monitoring treatment efficacy but, as a simple and noninvasive test, OR can be used with confidence.

Abstract
OBJECTIVE To evaluate the effect of nasal saline irrigation in the treatment of allergic rhinitis (AR) in children and to assess whether nasal saline irrigation could be used as a complementary therapy for AR in children in combination with the intranasal corticosteroids (INS). METHOD In total, 61 children with AR were divided into three groups: the nasal irrigation, intranasal corticosteroid, and combined treatment groups. Symptoms and signs of AR and eosinophils (EOS) in the nasal secretions were evaluated after 4 weeks, 8 weeks, and 12 weeks of treatment. RESULTS In AR children treated with nasal irrigation and a decreased the INS dose, a significant improvement in symptoms and signs and a significant decrease in the mean EOS count in nasal secretions were observed at week 12. CONCLUSION Nasal saline irrigation with physiological seawater is well tolerated and benefits the patients with AR, and can thus be considered a good adjunctive treatment option to maintain the effectiveness of the INS at a lower dose, thus resulting in reduced side effects and a decreased economic burden.

Abstract
Acoustic rhinometry and rhinomanometry are important tests used to assess nasal function. The degree to which the parameters of these tests are correlated is yet to be established. Objective This paper aimed to study the correlations between nasal resistance (NR) and acoustic rhinometry parameters in children and adolescents with allergic rhinitis and controls. Method Twenty patients with allergic rhinitis and 20 controls were enrolled. NR, volumes (V4, V5, V2-5), and minimal cross-sectional areas (MC1, MC2) were measured in three moments: baseline, after induction of nasal obstruction and after topical decongestant administration. Results Patients with allergic rhinitis had significant correlation between NR and all volumes (V5: r = -0.60) and with MC2. Among controls, MC1 was the parameter with the strongest correlation with NR at baseline (r = -0.53) and after decongestant administration. In the combined analysis, V5 had the highest correlation coefficients at baseline (r = -0.53), after obstruction (r = -0.58) and after decongestant (r = -0.46). Conclusions Our data showed that NR and acoustic rhinometry parameters have negative and significant correlations. Nasal volumes are, in general, better correlated than minimal cross-sectional areas. V5 was the parameter with the highest correlation in the rhinitis group and in the combined analysis.

Abstract
OBJECTIVE Our objective was to evaluate the action of topical nasal steroid in nasal congestion and nasal hyper-reactivity in children and adolescents with persistent allergic rhinitis. METHODS Twenty atopic children and adolescents (6 to 18 years) with moderate-to-severe persistent allergic rhinitis (PAR) were treated with mometasone furoate (100 microg once a day) for 21 days. At the beginning and end of treatment, the following were recorded: a) nasal symptoms score; b) several parameters of nasal congestion measured by acoustic rhinometry (SRE 2000 Rhinometrics); c) degree of nasal hyper-reactivity to histamine (concentration of histamine necessary to induce at least 100% increase in total nasal resistance during nasal provocation test). Data were compared with those from 20 controls. RESULTS Compared to controls, PAR patients had significantly higher score of symptoms, as well as higher degree of nasal hyper-reactivity and lower nasal volumes. After treatment, there was a significant decrease in the mean nasal symptoms score (8.0 versus 3.8; p < 0.001) and in the nasal hyper-reactivity (histamine concentration: 0.72 mg/ml versus 2.60 mg/ml; p < 0.001). Congestion improvement was observed by the increase in all acoustic rhinometry parameters. Among all studied volumes, the volume in the segment between 2 and 5 cm showed the highest mean increase (19.8%). CONCLUSION Treatment with topical nasal steroid objectively reduced nasal congestion and nasal histamine hyper-reactivity in children and adolescents with PAR.

Abstract
OBJECTIVE Current measurements of nasal obstruction are unreliable and may be improved with the development of new techniques. The effectiveness of odiosoft-rhino (OR) in the evaluation of nasal obstruction was investigated in a blind comparison at a referral center, institutional practice. PATIENTS Forty-eight patients with perennial allergic rhinitis and 52 healthy subjects were studied. Nasal endoscopic examination, acoustic rhinometry (AR), and OR were performed and symptom scores compared. MAIN OUTCOME MEASURE Assessment of nasal blockage with OR method was the main outcome measure. RESULTS Using the OR technique, significant differences were observed between the patient and control groups. OR data correlated with symptom scores and endoscopic examination. However, this was not observed with AR. A 15.5-dB cutoff point for the left side and 14.5 dB cutoff point for the right side at the 2,000 to 4,000 Hz frequency interval resulted in 93.8% sensitivity and 92.3% specificity and 72.9% sensitivity and 80.8% specificity, respectively. A 8.5-dB cutoff point for the left and right sides at the 4,000 to 6,000 Hz frequency interval resulted in 87.5% sensitivity and 80.8% specificity and 70.8% sensitivity and 78.8% specificity, respectively. CONCLUSION OR is a simple, noninvasive test for assessing nasal obstruction. The OR technique can detect nasal obstruction with high sensitivity and specificity, and these findings correlate with symptoms and physical examination.

Abstract
AIM OF THE STUDY To evaluate if perennial non-infectious rhinitis is associated with sleep disturbances in asthma. MATERIALS AND METHODS This is a questionnaire based study in a random population sample from Denmark, Estonia, Iceland, Norway and Sweden aged 30-54yr. A total of 1127 individuals reporting asthma from an original random population sample of 16,191 were analysed regarding their quality of sleep in relation to perennial non-infectious rhinitis. Perennial non-infectious rhinitis was defined as having nasal symptoms such as nasal blockage and secretion in the absence of common cold, always. Asthma was defined as both ever having had asthma and having physician diagnosed asthma. Odds ratios (OR) for difficulties inducing sleep, difficulties maintaining sleep, early morning awakenings and daytime sleepiness were calculated in a multiple logistic regression controlling for other risk factors for sleep disturbances such as snoring, wheeze, obesity and smoking. RESULTS The response rate was 74%. A total of 189 (17%) of the subjects with asthma reported perennial non-infectious rhinitis. Perennial non-infectious rhinitis was associated with an increased OR for difficulties maintaining sleep (1.6 (95% confidence interval (CI) 1.1-2.3)), early morning awakenings (1.5 (95% CI 1.1-2.2)) and daytime sleepiness (1.8 (95% CI 1.2-2.9)). The result show that perennial non-infectious rhinitis is an independant risk factor for sleep disturbances in asthma.

Abstract
PURPOSE OF REVIEW Nasal obstruction, the cardinal symptom of persistent (perennial) allergic rhinitis, is one of the most common symptoms encountered in primary care and in specialist clinics. It is difficult to quantify by clinical examination, and, hence, objective assessment of the nasal airway is critical to rhinologic research. Nasal obstruction in persistent allergic rhinitis must be treated the year round, and therefore treatment choices, costs, and compliance all become important public health issues. RECENT FINDINGS Many inflammatory and neurogenic mediators released during allergic reactions are able to cause plasma exudation and vasodilatation, with resultant edema and swelling of the nasal mucosa. Recently, technological advancements have made it possible to qualitatively and quantitatively study the nasal airway, providing greater insights into the understanding of physiological fluctuation and pathophysiological manifestations of nasal patency. From recent international guidelines, the management of allergic rhinitis includes combining treatments of the upper and lower airways, by using patient education, allergen avoidance, pharmacological treatment, and specific immunotherapy. Surgery may be needed as an adjunctive intervention. Multiple methods have been introduced to treat turbinate hypertrophy. However, preservation of adequate nasal mucosal function is important, together with long-term results. SUMMARY It is important that consensus recommendations for the management of allergic rhinitis be designed and implemented by all levels of medical specialists in order to improve treatment outcomes.
