Clinical Efficacy and Safety Study of Loratadine Combined with Glucocorticoid Nasal Spray in the Treatment of Pediatric Bronchial Asthma with Seasonal Allergic Rhinitis.

To investigate the clinical efficacy and safety of Loratadine combined with Glucocorticoid nasal spray in the treatment of pediatric bronchial asthma with seasonal allergic rhinitis. A total of 100 pediatric patients with moderate to severe bronchial asthma and seasonal allergic rhinitis admitted to our hospital between January 2020 and January 2023 were included in this study. All patients met the complete inclusion and exclusion criteria. Based on different treatment interventions, they were divided into the control group (n = 50) and the observation group (n = 50). Patients in the control group received treatment with glucocorticoid nasal spray, while patients in the observation group received combined intervention with Loratadine in addition to the treatment received by the control group. The clinical treatment outcomes, incidence of adverse reactions, as well as the scores of nasal symptoms, asthma control, and peak expiratory flow rates at different treatment time points (baseline, T1: 30 days after treatment, T2: 60 days after treatment, T3: 90 days after treatment) were compared between the two groups.The combined treatment of Loratadine with Glucocorticoid nasal spray demonstrates significant clinical efficacy in the treatment of pediatric bronchial asthma with seasonal allergic rhinitis. It further promotes the recovery of peak expiratory flow rates, improves symptoms of rhinitis and asthma in pediatric patients. Importantly, the application of this combined treatment does not increase the risk of adverse reactions in pediatric patients, indicating its high safety profile. This treatment approach is worthy of clinical application and further promotion.

Hypokalemic paralysis following intramuscular betamethasone injection: A case report and review of literature.

Acute neuromuscular paralysis is a relatively common condition in emergency rooms (ERs). They can be caused by several reasons, including adverse drug reactions. Betamethasone is a glucocorticoid commonly used for various conditions, such as allergic conditions. One of the rare but known side effects of glucocorticoids is hypokalemia. Rare cases of hypokalemia following high- and low-dose glucocorticoid injections have been reported. This study presents the history of a young, healthy male without significant past medical history who presented with an inability to stand and walk due to four-limb paralysis (more prominent in the lower limbs) following an intramuscular injection of a 4 mg betamethasone, which was prescribed for the treatment of allergic rhinitis. The patient was stabilized with an intravascular injection of potassium chloride diluted in 1000 mL of normal saline and monitored for 24 h, ruling out any other endocrine condition. Hypokalemia and its severe form are defined as the serum level of lower than 3.5 and 2.5 mEq/Lit, respectively. One of the etiologies of drug-induced hypokalemic paralysis is systemic glucocorticoid administration. In severe cases, it can cause quadriplegia and other neuromuscular, respiratory, and cardiac complications. Therefore, it is an urgent condition that should be managed carefully. Pregnant women who are receiving these medications are a specific group at risk of hypokalemic paralysis. There are several safer treatments for seasonal allergic rhinitis compared to systemic glucocorticoids, which should be considered by physicians. Moreover, paralysis in patients receiving these medications should be approached attentively since it might be caused by hypokalemia, which can be life threatening if not treated. It is advisable that the blood level of electrolytes, especially potassium, be checked for patients who present with paralysis or weakness after glucocorticoid injections.

Evaluation of the treatment strategy for complicated allergic rhinitis.

OBJECTIVE: Aim: To carry out a comprehensive evaluation of treatment modification for patients with seasonal allergic rhinitis (SAR) complicated by anxiety-neurotic disorders. PATIENTS AND METHODS: Materials and Methods: Patients with SAR in the acute stage on the background of anxiety disorders were studied. Immunological studies were carried out, an assessment of the dynamics of indicators of the quality of life of patients, the level of anxiety / depression was assessed. In the clinical group, a variant of therapy modification was proposed. RESULTS: Results: Significant changes in the subpopulation ratio of lymphocytes, an increase in the immunoregulatory index, which indicated the severity of the immunological process, were revealed in SAR patients in the acute stage against the background of anxiety disorders. At the same time, a significant activation of the humoral link of immunity was observed: an increase and a significant increase in IgE in the blood serum and an increase in the content of sIgA in the nasal secretion. In most patients, eosinophilia was found in the peripheral blood and in the rhinocytogram before treatment. In the study of the quality of life of patients, changes in many parameters were found. CONCLUSION: Conclusions: The combination of "Nazafort Allergy Protection" and Atarax seems to be the most successful, which significantly improved the physical and psycho-emotional state of patients with SAR, complicated by anxiety and neurotic disorders. This combination led to an increase in the stress resistance of patients.

Efficacy and safety of stapokibart (CM310) in uncontrolled seasonal allergic rhinitis (MERAK): an investigator-initiated, placebo-controlled, randomised, double-blind, phase 2 trial.

Background: There is no trial to assess the benefits of periodically using biologics during the pollen season in patients with uncontrolled seasonal allergic rhinitis (SAR), who have moderate-to-severe symptoms even after standard-of-care. This trial aimed to evaluate the efficacy and safety of the add-on administration of stapokibart, a humanised monoclonal antibody that targets interleukin-4 receptor alpha, in patients with uncontrolled SAR. Methods: In this investigator-initiated, randomised, double-blind, placebo-controlled trial, eligible patients received either stapokibart 600-300 mg weekly (QW), every 2 weeks (Q2W), or placebo QW for 4 weeks. All patients were given mometasone furoate nasal spray and loratadine throughout the trial. The primary endpoint was the mean change from baseline in daily reflective total nasal symptom score (rTNSS) during 2-week treatment. Secondary efficacy outcomes included: the mean change from baseline in daily rTNSS during 4-week treatment; the mean changes and the mean percentage changes from baseline during 2-week and 4-week treatment in 1) daily rTNSS and reflective total ocular symptom score (rTOSS), 2) morning (AM)/evening (PM) rTNSS and rTOSS, 3) AM instantaneous total nasal symptom score (iTNSS) and instantaneous total ocular symptom score (iTOSS), 4) individual nasal and ocular symptoms; the change from baseline in Rhinoconjunctivitis Quality of-Life Questionnaire score during 4-week treatment. Exploratory endpoints included the change of prespecified markers related to type 2 inflammation pre- and post-treatment. Safety, immunogenicity, and pharmacokinetics were also evaluated. This study is registered with www.clinicaltrials.gov (NCT05470647). Findings: Between August 17, 2022, and December 28, 2022, 92 patients with uncontrolled SAR were enrolled from 4 centres in China and randomly assigned to receive stapokibart 600-300 mg QW (n = 31), stapokibart 600-300 mg Q2W (n = 30), or placebo QW (n = 31), of whom 86 (93%) completed the study. Both stapokibart Q2W and QW did not significantly improve mean change from baseline in daily rTNSS compared with placebo in 2 weeks. The least-squares (LS) mean differences (97.5% confidence interval [CI]) compared with placebo were -1.0 (-2.3, 0.2) in stapokibart Q2W group (p = 0.065) and -0.2 (-1.5, 1.0) in stapokibart QW group (p = 0.67). For the secondary outcomes, compared with placebo, stapokibart Q2W presented significant improvements in the mean percentage change from baseline in daily rTNSS in 2 weeks (LS mean difference -12.9%, 95% CI -25.3%, -0.4%, p = 0.043), as well as AM iTNSS over 2 weeks (LS mean difference -17.4%, 95% CI -31.0%, -3.8%, p = 0.013) and 4 weeks (LS mean difference -15.4%, 95% CI -29.0%, -1.9%, p = 0.026). Additionally, the nasal congestion score was significantly lower in stapokibart Q2W than placebo during 2-week (LS mean difference -0.4, 95% CI -0.7, -0.1, p = 0.014) and 4-week (LS mean difference -0.4, 95% CI -0.7, -0.04, p = 0.028) treatment. Treatment-emergent adverse events (TEAEs) occurred in 48% (15/31), 33% (10/30), and 61% (19/31) of patients receiving stapokibart QW, Q2W, and placebo, respectively. Most reported TEAEs were sinus bradycardia, hyperlipidaemia, and blood uric acid increased. Interpretation: In this phase 2 trial, both stapokibart regimens had an acceptable safety and tolerability profile but did not significantly improve daily rTNSS in patients with uncontrolled SAR. The efficacy of stapokibart in patients with uncontrolled SAR is being further investigated in ongoing phase 3 trials (clinicaltrials.gov, NCT05908032).

Nine-Year Trend in the Prevalence of Allergic Diseases and Their Associated Factors in Young Adults.

INTRODUCTION: Notably, few studies have evaluated the recent changes in the prevalence of allergic diseases in young adults. Studies examining the risk of allergy in two populations with similar social backgrounds, other than the region in which they live, are rare. METHODS: First-year students from Hokkaido University were enrolled in this study between 2011 and 2019. A questionnaire survey was conducted to determine the annual prevalence of current wheeze, seasonal allergic rhinitis (SAR), and perennial allergic rhinitis (PAR) in nonsmoking young adults. Trends in the presence of these disease conditions were evaluated based on their hometowns (Hokkaido and outside Hokkaido separately) due to the low prevalence of cedar pollen allergies in Hokkaido. The association between these disease conditions and body mass index (BMI) was also assessed. RESULTS: The prevalence of current wheeze and PAR food allergies did not change in both regions. SAR showed a significantly increasing trend; however, the prevalence of SAR was higher among those whose place of origin was not Hokkaido. Current wheeze was positively associated with obesity (p < 0.05), whereas the high prevalence of SAR was not associated with body weight. In contrast, a lean body type was significantly associated with a higher prevalence of PAR (p < 0.05). DISCUSSION/CONCLUSION: The prevalence of current wheeze was stable and that of PAR has decreased over the past 9 years. However, the prevalence of SAR in Hokkaido has been increasing in Japanese young adults. A differential association between current wheeze and BMI was observed when comparing PAR and SAR.

Decreased Basophil Activation against House Dust Mite after Japanese Cedar Pollen Subcutaneous Immunotherapy: A Retrospective Study.

BACKGROUND: Allergen-specific immunotherapy (AIT), an established treatment for allergic diseases, prevents the development of other allergic manifestations. Although the mechanisms remain unclear, AIT has been shown to reduce basophil activation (BA) against nontarget allergens. OBJECTIVES: The aim of this study was to assess immunological changes in Dermatophagoides farinae (Der f) after Japanese cedar pollen (JCP)-based subcutaneous immunotherapy (SCIT) monotherapy. METHOD: The data of 16 patients (age: 6-37 years) with JCP-induced allergic rhinitis who were sensitive to Der f (serum Der f-specific immunoglobulin E [IgE] level >0.34 kUA/L) and received JCP-based SCIT for 5 years were reviewed retrospectively. BA by Der f and JCP extracts and serum-specific IgE and immunoglobulin G4 (IgG4) levels against these allergens were evaluated before and after completing 5 years of JCP-based SCIT monotherapy. RESULTS: The areas under the dose-response curves of BA by Der f and JCP extracts were significantly reduced (p = 0.02 and p = 0.002, respectively). JCP-specific IgE levels decreased and JCP-specific IgG4 levels increased significantly (p < 0.001 for both), whereas Der f-specific IgE and IgG4 levels did not change significantly. CONCLUSIONS: JCP-based SCIT monotherapy reduced Der f-specific BA. These findings suggest that JCP-based SCIT has the potential to modulate immune response toward nontarget allergens.

Back to basics: likelihood ratios for olive and grass pollen specific IgE in seasonal allergic rhinitis.

Introduction: Specific IgE (sIgE) is merely a sensitization marker that cannot be used for allergy diagnosis if there are no associated clinical symptoms. As of 2023, there is still no evidence regarding the quantity of sIgE necessary to confirm or exclude clinical disease. Therefore, this study aimed to calculate cut-offs for sIgE, allowing us to effectively diagnose olive or grass pollen allergy and select allergenic immunotherapy (AIT) candidate patients in a region under high olive and grass allergenic pressure. Methods: An observational retrospective study consisting of the review of electronic medical records from 1,172 patients diagnosed with seasonal rhino-conjunctivitis and suspected allergy to olive or grass pollen. Symptoms correlated with sIgE to Poaceae and Oleaceae whole extracts and sIgE to genuine allergenic components were evaluated. Optimal cut-off values were calculated using receiver operating characteristic curves. Relevant clinical symptoms and AIT indications were taken into consideration when determining the clinical allergy diagnosis. Results: sIgE to Lolium showed the best area under the curve (AUC) for both diagnosis (0.957) and an indication of AIT (0.872). The optimal cut-off values for grass diagnosis and AIT indication were 1.79 kUA/L and 8.83 kUA/L, respectively. A value of 5.62 kUA/L was associated with a positive likelihood ratio (LR) of 10.08 set for grass allergy. Olea sIgE showed the best AUC for the diagnosis (0.950). The optimal cut-off for diagnosis was 2.41 kUA/L. A value of 6.49 kUA/L was associated with a positive LR of 9.98 to confirm olive pollen allergy. In regard to immunotherapy, Ole e 1 sIgE showed the best AUC (0.860). The optimal cut-off was 14.05 kUA/L. Ole e 1 sIgE value of 4.8 kUA/L was associated with a 0.09 negative LR to exclude olive AIT indication. Conclusions: The sIgE cut-offs found in this population under high olive and grass allergenic pressure reduce the gap between sensitization and clinical allergy, providing a new tool for the diagnosis of seasonal allergic rhinitis/asthma and helping to discriminate patients who will benefit from AIT.

Bioequivalence of 2 Pediatric Formulations of Fexofenadine Hydrochloride Oral Suspension.

Fexofenadine hydrochloride (HCl) is a second-generation, nonsedating, histamine H1-receptor antagonist used to manage seasonal allergic rhinitis and chronic idiopathic urticaria. A new oral pediatric suspension of fexofenadine HCl has been developed, with the preservative potassium sorbate replacing parabens. The objective of this phase 1 single-center, open-label, randomized, 2-treatment, full-replicated, 4-period, 2-sequence crossover study in healthy adult volunteers was to assess the bioequivalence of 30 mg of the new oral suspension of fexofenadine HCl (test) versus 30 mg of the marketed pediatric oral suspension of fexofenadine HCl (reference). The replicate design was based on the high intra-individual variability of fexofenadine (>30% on Cmax ). The study comprised 68 randomized and treated volunteers. Plasma concentrations of fexofenadine were similar following the administration of a single dose of each formulation. Cmax , AUClast , AUC, median tmax , and mean t1/2z were similar between administrations of the same fexofenadine formulation and between formulations. A high intra-individual variability was confirmed with both formulations. Bioequivalence of the test and reference fexofenadine HCl formulations was demonstrated as the 90% confidence intervals of the geometric least squares mean ratio for Cmax , AUClast , and AUC of fexofenadine were all within the bioequivalence range of 0.80-1.25. There were no serious adverse events (AEs) or study discontinuations due to treatment-emergent AEs with either fexofenadine HCl formulation. The new paraben-free fexofenadine HCl 30-mg oral suspension and marketed fexofenadine HCl 30-mg pediatric oral suspension are bioequivalent under fasting conditions, with no safety concerns and a safety profile consistent with the known profile of fexofenadine.

A Clinical Study to Assess the Efficacy and Safety of MP-AzeFlu Nasal Spray in Comparison to Commercially Available Azelastine Hydrochloride and Fluticasone Propionate Nasal Sprays in Chinese Volunteers with Allergic Rhinitis.

INTRODUCTION: The objective of the present study was to evaluate the efficacy and safety of MP-AzeFlu nasal spray in comparison to commercially available azelastine hydrochloride and fluticasone propionate sprays in Chinese patients with moderate-to-severe allergic rhinitis (AR). METHODS: We conducted a 14-day multicenter, randomized, double-blind, active controlled prospective clinical study in adult and adolescent patients with AR, who had moderate-to-severe symptoms. The primary efficacy endpoint was the change from baseline in combined 12-h reflective total nasal symptom score (rTNSS) (morning [AM] + afternoon [PM]). The safety profile of the study medications was assessed through the recording, reporting, and analysis of baseline medical conditions, adverse events (AEs), vital signs, and focused nasal examination. Three hundred patients per treatment group were randomized, which led to a total sample size estimation of 900 patients. RESULTS: MP-AzeFlu group showed significantly higher symptom reduction for the entire 2-week treatment period in rTNSS when compared with the AZE group (LS mean difference: - 1.96; 95% CI: - 2.53, - 1.39; p < 0.0001), or the FLU group (LS mean difference: - 0.98; 95% CI: - 1.55, - 0.41; p = 0.0007). The results of adult RQLQ showed improvement in QoL in all treatment groups. Except for dysgeusia (bitter taste) that was reported by more patients (13 [4.3%]) in the MP-AzeFlu group, the incidence of all other TEAEs in the MP-AzeFlu group was comparable or even lower than in other treatment groups. CONCLUSIONS: MP-AzeFlu, when administered as one spray per nostril twice daily for 14 days, alleviated AR symptoms in Chinese patients with moderate-to-severe AR.

The Combined Effects of Sublingual Immunotherapy and Lactobacillus acidophilus-Producing Extract on Cedar Pollinosis Symptoms.

INTRODUCTION: Sublingual immunotherapy (SLIT), in which standardized cedar pollen extract solution is administered, has been used to treat cedar pollinosis, but SLIT is problematic because it takes a long time to become effective, and some cases are ineffective even after long-term treatment. It has also been reported that lactobacillus acidophilus extract (LEX), a food-derived ingredient, alleviates various allergic symptoms. This study examined the usefulness of LEX as a treatment for cedar pollinosis in comparison with SLIT. We also examined whether the combined use of SLIT and LEX could have an early-onset of therapeutic effect on cedar pollinosis. We also examined the usefulness of LEX as a salvage therapy for patients who failed to respond to SLIT. SUBJECTS AND METHODS: Fifteen patients with cedar pollinosis were divided into three groups. The three groups were: three patients in the standardized cedar pollen extract group (S group), seven patients in the lactobacillus-producing extract group (L group), and five patients in the combination group of standardized cedar pollen extract and lactobacillus-producing extract (SL group). The subjects were treated for three years, corresponding to the three scattering seasons of cedar pollen, and observed according to the evaluation items. The evaluation items were severity score based on examination findings, subjective symptom score (QOL score) based on the Japanese Standard QOL Questionnaire for Allergic Rhinitis (JRQLQ No. 1) questionnaire, nonspecific IgE level measurement by blood test, and cedar pollen-specific IgE level measurement. RESULTS: After three years of observation, there were no significant differences in severity score and nonspecific IgE levels among the three groups, while QOL score decreased significantly between the first and third years of treatment in the L group. Cedar pollen-specific IgE levels in the S and SL groups showed an increase in the first year and a gradual decrease in the second and third years of treatment compared to the pre-treatment period. In group L, no increase was observed in the first year, and a significant decrease was observed in the second and third years during the cedar pollen dispersal period. CONCLUSIONS: The results of severity and quality of life scores indicated that it took three years of treatment for the S and SL groups to show efficacy, while the L group showed improvement in quality of life scores and cedar pollen-specific IgE levels from the first year, suggesting that LEX is useful as a treatment for cedar pollinosis. The efficacy of combination therapy with SLIT and LEX was not clear, but since the effect of LEX was observed from the early stage of treatment, it was thought that the combination therapy with LEX intake from the early stage of treatment may be effective in reducing the incidence of ineffective cases. The combination therapy of SLIT and LEX may also be useful as a salvage therapy.

Factors predicting the outcome of allergen-specific nasal provocation test in children with grass pollen allergic rhinitis.

Background: Nasal provocation testing (NPT) is a reference methodology to identify the culprit allergen in patients with allergic rhinitis. Selecting the right allergen for NPT is particularly difficult in poly-sensitized patients with seasonal allergic rhinitis (SAR). Predictors of NPT outcomes may facilitate the proper use of this test or even substitute it. Objective: To identify predictors of grass pollen NPT outcome from an array of clinical data, e-diary outcomes, and allergy test results in poly-sensitized pediatric patients with SAR. Methods: Poly-sensitized, SAR patients with grass pollen allergy, participating in the @IT.2020 pilot project in Rome and Pordenone (Italy), participated in a baseline (T0) visit with questionnaires, skin prick testing (SPT), and blood sampling to measure total (ImmunoCAP, TFS, Sweden) and specific IgE antibodies to grass pollen extracts and their major allergenic molecules (ESEP, Euroimmun Labordiagnostika, Germany). During the pollen season, patients filled the AllergyMonitor® e-diary app measuring their symptoms, medication intake, and allergy-related well-being via the Visual Analogue Scale (VAS). After the pollen season (T1), patients answered clinical questionnaires and underwent a nasal provocation test (NPT) with grass pollen extract. Results: We recruited 72 patients (age 14.3 ± 2.8 years, 46 males) sensitized to grass and/or other pollens, including olive (63; 87.5%) and pellitory (49; 68.1%). Patients positive to grass pollen NPT (61; 84.7%), compared to the negative ones, had worse VAS values in the e-diary, larger SPT wheal reactions, and higher IgE levels, as well as specific activity to timothy and Bermuda grass extracts, rPhl p 5 and nCyn d 1. A positive NPT to grass pollen was predicted by an index combining the specific activity of IgE towards Phl p 5 and Cyn d 1 (AUC: 0.82; p < 0.01; best cut-off ≥7.25%, sensitivity 70.5%, specificity: 90.9%). VAS results also predicted NPT positivity, although with less precision (AUC: 0.77, p < 0.01; best cut-off ≥7, sensitivity: 60.7%, specificity: 81.8%). Conclusions: An index combining the specific activity of IgE to rPhl p 5 and nCyn d 1 predicted with moderate sensitivity and high specificity the outcome of a grass pollen NPT in complex, poly-sensitized pediatric patients with seasonal allergic rhinitis. Further studies are needed to improve the index sensitivity and to assess its usefulness for NPT allergen selection or as an alternative to this demanding test procedure.

Profiles of immune infiltration in seasonal allergic rhinitis and related genes and pathways.

BACKGROUND: Seasonal allergic rhinitis (SAR) is a chronic inflammatory disease for which the molecular mechanism is unclear. METHODS: Whole blood, CD4+ T cells in peripheral blood mononuclear cells (PBMCs), and CD4+ T cells in nasal mucosa from SAR-related datasets (GSE43497, GSE50223, and GSE49782) were downloaded from the Gene Expression Omnibus (GEO) database. Differences in SAR-associated immune cell infiltration in the PBMCs were analyzed using the CIBERSORT algorithm. Differential gene expression analysis was conducted between different groups. Gene set enrichment analysis (GSEA) was performed using the clusterProfiler package to explore functional changes in signaling pathways. RESULTS: There was a significant increase in the proportion of CD8+ T cells and a significant decrease in the proportion of neutrophils in the whole blood of SAR patients after allergen challenge compared to SAR patients after diluent challenge. This pattern was also found in SAR patients compared to healthy controls (HCs) by flow cytometry. The NF-κB and Toll-like receptor signaling pathways were enriched in SAR patients following allergen challenge. The expression of CD4+ T cell marker genes and associated cytokines significantly differed between allergen-treated SAR patients, diluent-treated SAR patients and HCs. We also observed heightened CD4+ T cell related genes, cytokines and pathways activation in the nasal mucosa region of SAR patients after allergen challenge. CONCLUSION: Our analysis revealed that T cell receptor signaling pathways, T helper 1 (Th1) /T helper 2 (Th2) cell differentiation may contribute to the development of SAR. The present study is the first bioinformatic analysis to quantify immune cell infiltration and identify underlying SAR mechanisms from combined microarray data and provides insight for further research into the molecular mechanisms of SAR.

[Acupuncture for prevention of moderate to severe seasonal allergic rhinitis: a randomized controlled trial].

OBJECTIVE: To observe the clinical efficacy of acupuncture for prevention of moderate to severe seasonal allergic rhinitis. METHODS: A total of 105 patients with moderate to severe seasonal allergic rhinitis were randomly divided into an observation group (53 cases, 3 cases dropped off) and a control group (52 cases, 4 cases dropped off). The patients in the observation group were treated with acupuncture at Yintang (GV 24+), Yingxiang (LI 20), Hegu (LI 4), Zusanli (ST 36), Fengchi (GB 20), Feishu (BL 13), etc. 4 weeks before the seizure period, once every other day, 3 times a week for 4 weeks. The patients in the control group were not given any intervention before the seizure period. Emergency drugs can be given appropriately during the seizure period in both groups. After seizure period, the seizure rate was recorded in the two groups; before treatment and on week 1, 2, 4, 6 of seizure period after treatment, the rhinoconjunctivitis quality of life questionnaire (RQLQ) score and total nasal symptom score (TNSS) were observed in the two groups; the rescue medication score (RMS) was recorded on week 1-6 of seizure period in the two groups. RESULTS: The seizure rate of the observation group was 84.0% (42/50), which was lower than 100.0% (48/48) in the control group (P<0.05). After treatment, the scores of RQLQ and TNSS at each time point of seizure period were decreased compared with before treatment in the observation group (P<0.01), which were lower than the control group (P<0.01). The RMS score at each time point of seizure period in the observation group was lower than the control group (P<0.05, P<0.01). CONCLUSION: Acupuncture can reduce the incidence of moderate to severe seasonal allergic rhinitis, relieve the symptoms, improve the quality of life and reduce the use of emergency drugs.

Molecular Aspects of Allergen-Specific Immunotherapy in Patients with Seasonal Allergic Rhinitis.

A systematic review and narrative synthesis of publications was undertaken to analyze the role of component-resolved diagnosis technology in identifying polysensitization for the provision of allergen-specific immunotherapy to patients with seasonal allergic rhinitis. A search of publications was carried out in electronic databases in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search helped to identify 568 publications, 12 of which were included in this review. Overall, 3302 patients were enrolled. The major finding was that component-resolved diagnostics change the choice of relevant allergens for allergen-specific immunotherapy in at least 50% of cases. Sensitization to allergen components differs with age, type of disease, and overall disease duration. Patients who had both bronchial asthma and allergic rhinitis were sensitized to a larger number of allergens than patients who had bronchial asthma alone.

Real-Life Effectiveness of MP-AzeFlu (Dymista®) in Swedish Patients with Persistent Allergic Rhinitis, Assessed by the Visual Analogue Scale.

Background: Many allergic rhinitis (AR) patients have moderate/severe persistent disease. MP-AzeFlu (Dymista®) comprises intranasal azelastine hydrochloride and fluticasone propionate in a novel formulation delivered in a single device. Objective: This prospective, noninterventional study assessed the effectiveness of MP-AzeFlu (one spray/nostril twice daily; azelastine hydrochloride = 548 µg; fluticasone propionate = 200 µg) on relieving AR symptom severity. Methods: A visual analogue scale (VAS; 0 mm [not at all bothersome] to 100 mm [very bothersome]) was used during a 42-day MP-AzeFlu treatment period by 161 persistent AR (PER) patients in routine clinical practice in Sweden. Patients also assessed their sleep quality. Results: VAS scores decreased from baseline during the treatment period and patients achieved a clinically relevant VAS score cutoff before Day 7, with 89.3% reporting well or partly controlled symptoms on Day 1. VAS score decreased from 61.4 ± 22.4 mm (baseline) to 32.1 ± 24.6 mm on Day 28 and 26.1 ± 24.3 mm on Day 42 (both p < 0.0001), an overall reduction from baseline on Day 42 of 38.1 ± 28.2 mm. The percentage of patients with very good/good sleep quality increased from 3.7%/28.6% on Day 0 to 16.5%/51.5% on Day 42. Conclusion: MP-AzeFlu provides effective, rapid control of PER assessed by VAS in a real-world clinical setting in Sweden. Symptom improvement was observed at Day 1, sustained for 42 days, and associated with improved sleep quality. MP-AzeFlu significantly improved the QoL of the patients and was well tolerated.

Atopic Manifestations Are Underestimated Clinical Features in Various Primary Immunodeficiency Disease Phenotypes.

BACKGROUND AND OBJECTIVES: Atopic manifestations are described as a clinical feature of various primary immunodeficiency disease (PID) phenotypes and are frequently reported in combined immunodeficiencies. The prevalence of atopic manifestations in other PIDs remains largely unknown. Objective: To evaluate the prevalence of atopic manifestations in PIDs other than combined immunodeficiencies and to identify in which PIDs atopic manifestations are most common with the aim of improving patient care. METHODS: A partner-controlled, questionnaire-based study was performed in pediatric and adult PID patients. Data from diagnostic tests to assess atopic manifestations (ie, diagnostic criteria for atopic dermatitis, spirometry, specific IgE against food and inhalant allergens) were collected from adult patients to confirm patient-reported atopic manifestations. RESULTS: Forty-seven children and 206 adults with PIDs and 56 partner-controls completed the questionnaire. Thirty-five pediatric patients (74.5%) and 164 adult patients (79.6%) reported having experienced 1 or more atopic manifestations compared with 28 partner-controls (50.0%). In the comparison of adult patients with partner-controls, prevalence values were as follows: atopic dermatitis, 49.5% vs 27.3% (P=.003); food allergy, 10.7% vs 1.9% (P=.031); asthma, 55.7% vs 14.8% (P<.001); and allergic rhinitis, 49.8% vs 21.8% (P<.001). The frequency of current atopic manifestations reported by patients was higher than the prevalence based on diagnostic tests (atopic dermatitis, 11.2%; food allergy, 1.9%; asthma 16.4%; and allergic rhinitis, 11.5%). CONCLUSION: Atopic manifestations are prevalent clinical features across a broad spectrum of PIDs and, in our cohort, frequently present in patients with combined immunodeficiencies and predominant antibody deficiencies. Atopic manifestations should be evaluated in patients with PIDs.

Quail egg homogenate with zinc as adjunctive therapy in seasonal allergic rhinitis: a randomised, controlled trial.

OBJECTIVE: Because most available treatments for managing seasonal allergic rhinitis show some side effects without reducing recurrence, natural anti-allergic products could represent an interesting treatment addition. This study aimed to analyse the efficacy and tolerance of quail egg as adjunctive therapy in seasonal allergic rhinitis. METHOD: In a Consolidated Standards of Reporting Trials compliant framework, patients with seasonal allergic rhinitis were prospectively randomised to receive mometasone nasal spray for four weeks or the same topical corticosteroid therapy plus commercially available oral quail egg and zinc tablets. RESULTS: Forty patients were enrolled. The mometasone + quail egg and zinc tablets group showed a greater reduction in nasal itching, sneezing and total nasal symptom scores than the mometasone nasal spray only group. A higher proportion of participants in the mometasone + quail egg and zinc tablets group had good rhinitis control than in the mometasone nasal spray only group, with no need for rescue medications. CONCLUSION: Despite the need for a further larger study, quail egg preliminarily appears to be an effective adjunct to topical steroid therapy in seasonal allergic rhinitis.

Increased Focus on Internal Body Sensations Is Associated with Higher Patient-Perceived Severity of Allergic Rhinitis.

BACKGROUND: Monitoring allergic rhinitis (AR) severity with objective biomarkers is important for the clinical management of patients as well as for research purposes. The most commonly used tool for the assessment of AR severity is the Total Nasal Symptom Score (TNSS). Objective biomarkers like skin prick test size or specific IgE levels do not correlate with TNSS. OBJECTIVE: We hypothesize that the psychological factors are the missing link between patient-perceived severity of AR and objective biomarkers. METHOD: Thirty-nine patients (median age: 34 years; 21 [54%] female) with grass pollen-related AR were enrolled in our study. Patients allergic for perennial allergens and allergens with potentially overlapping seasons including cypress, ash/olive, plane, and nettle families were excluded. Patient-reported outcomes included symptom score, medication scores, combined score, and Juniper Mini Rhinitis Quality of Life Questionnaire (minRQLQ). Psychometric evaluation was performed using 5 different psychological questionnaires that measure 13 different psychological factors. RESULTS: There was a significant correlation between the symptom score and private body consciousness (r = 0.50, p = 0.001) and neuroticism (R = 0.41 and p = 0.01). There was also a statistically significant correlation between the combined score and private body consciousness (r = 0.49 and p = 0.001) and with perceiving and understanding emotions (r = 0.34 and p = 0.04). The miniRQLQ score had a positive correlation with private body consciousness (r = 0.55 and p = 0.002) and observing (r = 0.42 and p = 0.02). CONCLUSIONS: Our data suggest that patients who are more aware of internal stimuli, as well as those who are highly self-conscious and somatically concerned tend to experience more severe AR symptoms.

Empirical Study on Promotion of Appropriate Pharmacotherapy in Patients with Seasonal Allergic Rhinitis / 社会薬学

The prevalence of seasonal allergic rhinitis (hereinafter “hay fever”) is increasing annually. While self-medication with over-the-counter (OTC) drugs is growing, some hay fever patients also use OTC drugs alongside medical visits. Issues arising from co-administration, such as excessive dosing and reduced quality of life (QOL) due to drowsiness, have been highlighted. However, no research has investigated the factors contributing to the concomitant use of prescribed and OTC drugs. Therefore, this study examined the following three patient groups: those using only prescribed drugs, those using only OTC drugs, and those using a combination of both. Initial analyses compared adherence, overuse extent, QOL (as measured by the Japanese Rhino-conjunctivitis Quality of Life Questionnaire [JRQLQ]), treatment satisfaction, lifestyle habits, and health literacy (as measured by the Communicative and Critical Health Literacy Scale [CCHL]) among the groups. Subsequently, a multinomial logistic regression analysis focusing on combination users identified factors associated with co-administration. The results revealed that combination users exhibited lifestyle issues and lower QOL compared to those using prescribed or OTC drugs only, although differences in CCHL were not significant. Furthermore, co-administration was linked to social life-related JRQLQ and excessive usage during symptom onset. In conclusion, patients with hay fever should avoid the concurrent use of prescribed and OTC drugs. Co-administration may not necessarily improve symptoms and might even lead to overuse risks. Thus, patients should be guided to consult medical professionals before purchasing OTC drugs, and lifestyle improvements should be emphasized as well.

Acupuncture for prevention of moderate to severe seasonal allergic rhinitis: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the clinical efficacy of acupuncture for prevention of moderate to severe seasonal allergic rhinitis.@*METHODS@#A total of 105 patients with moderate to severe seasonal allergic rhinitis were randomly divided into an observation group (53 cases, 3 cases dropped off) and a control group (52 cases, 4 cases dropped off). The patients in the observation group were treated with acupuncture at Yintang (GV 24+), Yingxiang (LI 20), Hegu (LI 4), Zusanli (ST 36), Fengchi (GB 20), Feishu (BL 13), etc. 4 weeks before the seizure period, once every other day, 3 times a week for 4 weeks. The patients in the control group were not given any intervention before the seizure period. Emergency drugs can be given appropriately during the seizure period in both groups. After seizure period, the seizure rate was recorded in the two groups; before treatment and on week 1, 2, 4, 6 of seizure period after treatment, the rhinoconjunctivitis quality of life questionnaire (RQLQ) score and total nasal symptom score (TNSS) were observed in the two groups; the rescue medication score (RMS) was recorded on week 1-6 of seizure period in the two groups.@*RESULTS@#The seizure rate of the observation group was 84.0% (42/50), which was lower than 100.0% (48/48) in the control group (P<0.05). After treatment, the scores of RQLQ and TNSS at each time point of seizure period were decreased compared with before treatment in the observation group (P<0.01), which were lower than the control group (P<0.01). The RMS score at each time point of seizure period in the observation group was lower than the control group (P<0.05, P<0.01).@*CONCLUSION@#Acupuncture can reduce the incidence of moderate to severe seasonal allergic rhinitis, relieve the symptoms, improve the quality of life and reduce the use of emergency drugs.
