Novel, Alternative, and Controversial Therapies of Rhinitis

Integration of bioinformatics analysis, molecular docking and animal experiments to study the therapeutic mechanisms of berberine against allergic rhinitis

Allergic rhinitis is a prevalent inflammatory condition that impacts individuals of all age groups. Despite reports indicating the potential of berberine in alleviating allergic rhinitis symptoms, the specific molecular mechanisms and therapeutic targets of berberine remain unclear. This research aims to explore the pharmacological mechanism of berberine in the treatment of allergic rhinitis through bioinformatic analyses and experimental validation. The research utilized public databases to identify potential targets of berberine. Furthermore, differentially expressed genes (DEGs) related to allergic rhinitis were pinpointed from the GSE52804 dataset. Through bioinformatics techniques, the primary targets were discovered and key KEGG and GO-BP pathways were established. To confirm the therapeutic mechanisms of berberine on allergic rhinitis, an OVA-induced allergic rhinitis model was developed using guinea pigs. We identified 32 key genes responsible for the effectiveness of berberine in treating allergic rhinitis. In addition, five central genes (Alb, Il6, Tlr4, Ptas2, and Il1b) were pinpointed. Further examination using KEGG and GO-BP pathways revealed that the main targets were primarily involved in pathways such as NF-kappa B, IL-17, TNF, and inflammatory response. Molecular docking analysis demonstrated that berberine exhibited strong affinity towards these five key targets. Furthermore, the expression levels of IL-6, TLR4, PTGS2, and IL-1β were significantly upregulated in the model group but downregulated following berberine treatment. This research has revealed the mechanism through which berberine combats allergic rhinitis and has identified its potential to regulate pathways linked to inflammation. These discoveries provide valuable insights for the development of novel medications for the treatment of allergic rhinitis.

[The effectiveness of complex drugs in the treatment of acute rhinitis]

Purpose of the study. Generalization of data on the value of alternative and additional treatment of acute infectious rhinitis with Korizalia.

MATERIAL AND METHODS

The material of scientific publications included in the Cochrane Library, information bases of the RSCI, MEDLINE, PubMed was used as a data source. The choice of material was carried out using the key words: colds, acute rhinitis, herbal medicine, homeopathic remedies.

RESULTS

Analysis of published clinical trial descriptions suggests the potential value of homeopathic medicines, in particular Korizalia, in improving the effectiveness of the treatment of acute rhinitis. The use of Korizalia in acute infectious rhinitis was more effective in relation to the main symptoms of ARI compared with placebo.

CONCLUSION

The lack of optimal drugs for the etiotropic treatment of viral acute respiratory infections determines the relevance of alternative and complementary methods of treatment using drugs of natural origin. The drug Korizalia can be used for acute respiratory infections (acute infectious rhinitis) as an alternative drug or in combination with other drugs.

Effect of the Use of Intranasal Spray of Essential Oils in Patients with Perennial Allergic Rhinitis: A Prospective Study

INTRODUCTION

Among allergic rhinitis (AR) symptoms, nasal obstruction particularly affects the quality of life. Antihistamines and intranasal corticosteroids are the most frequently prescribed symptomatic drugs, but their efficacy is often incomplete. Essential oils (EO) have shown an anti-inflammatory effect and potential in treating patients with AR. The aim of this study was to evaluate the effectiveness of a hypertonic EO-based nasal spray on perennial AR (PAR) symptoms.

METHODS

This prospective, open-label, non-randomized, multicentric trial included 43 patients with PAR sensitized to mites, not controlled for more than a year. All were treated with Puressentiel® Respiratory-Decongestant Nasal Spray for 30 days. Their usual treatment remained unchanged during the study period. Before and after treatment, each participant filled out a rhinitis questionnaire, the Allergic Rhinitis Control Test (ARCT). A nasal inspiratory peak flow (NIPF) was performed.

RESULTS

The mean ARCT was 16.4 and 20.5 at D0 and D30, respectively (p < 0.001); the mean increase between D0 and D30 was 4.1 (p < 0.001). The proportion of patients with controlled rhinitis after 30 days of treatment was 69.8 versus 14% before treatment (p < 0.001). The mean NIPF was 86.5 L/min and 105.1 L/min at D0 and D30, respectively (p < 0.001); the mean increase between D0 and D30 was 18.5 L/min.

CONCLUSION

A hypertonic EO-based nasal spray could be a new and natural option in the management of PAR. It could also be used as an add-on therapy when nasal symptoms are not fully controlled.

[Effect of sublingual immunotherapy with Dermatophagoides Farinae on the expression of specific IgG4 in patients with allergic rhinitis in Hainan area]

Objective:The aim of this study is to investigate the effect of sublingual immunotherapy with Dermatophagoides Farinae on the expression of specific IgG4（sIgG4） in patients with allergic rhinitis （AR） in Hainan area. Method:Seventy-two patients with dust-mite allergic rhinitis, all three generations of whom were local islanders in Hainan, were randomly divided into control group（36 cases） and SLIT group（36 cases）. sIgG4 and sIgE expression levels were detected before treatment, 6 months after treatment, 12 months after treatment, and 18 months after treatment. The patient's symptom score, medication score, VAS score and adverse reactions was also assessed. Finally, through statistical analysis of the relevant data collected at 4 time points in the two groups of patients, the efficacy, safety and changes of sIgG4 antibody expression level in patients with allergic rhinitis receiving sublingual specific immunotherapy in Hainan were observed. Result:Symptoms scores, medication scores and VAS scores were significantly improved in the SLIT group after treatment compared with before treatment（P<0.05）, and serum sIgG4 increased significantly（P<0.01）, serum sIgE showed no significant change（P>0.05）. In the control group, symptom scores, medication scores and VAS scores were also significantly improved compared with before treatment（P<0.05）, while serum sIgG4 and sIgE showed no significant change（P>0.05）. When comparing the two groups, Symptoms scores, medication scores and VAS scores of the SLIT group were significantly lower than those of the control group at 12 months and 18 months after treatment（P<0.05）. sIgG4 expression levels in the SLIT group were significantly higher than those in the control group after 6, 12 and 18 months of treatment（P<0.01）. There was no significant difference in sIgE expression level between the two groups（P>0.05）. No severe systemic adverse reactions occurred in the two groups, and 3 patients showed mild adverse reactions in the SLIT group. Conclusion:Sublingual immunotherapy of Dermatophagoides Farinae was effective and could increase the expression of sIgG4 in patients with Dermatophagoides farinae AR, sIgG4 is expected to be an immunological marker for the objective evaluation of the clinical efficacy of Hapten.

Exercise and Rhinitis in Athletes

Peak sporting performance requires optimal levels of health and fitness. Rhinitis, with its proven detrimental effects on sleep and mood, and its association with asthma, can clearly compromise athletic ability. Nasal health is therefore of key importance to the athlete. While not a limiting factor in a single exercise effort, the effects of nasal dysfunction can have repercussions in the post-exercise recovery period. Furthermore, it is linked with the development of asthma and may increase susceptibility to upper respiratory tract symptoms. This review aims to investigate the physiology of the nose during exercise, examine the relationship between exercise and nasal dysfunction, and consider the impact that dysfunction may have on an athlete. Lastly, the authors describe the diagnosis and treatment of rhinitis in athletes.

Recent advances in allergic rhinitis

Allergic rhinitis affects 20 to 30% of adults in both the United States and Europe and perhaps a somewhat higher percentage of children. In addition to nasal and ocular symptoms directly related to the allergic process, interference of these symptoms with sleep leads to daytime sleepiness and impaired quality of life. Patients miss work because of symptoms but an even greater problem is interference with work productivity, or presenteeism, which has been reported to be the biggest contributor to the total economic cost of allergic rhinitis. There has been increasing awareness that many patients with either seasonal or perennial symptoms but negative skin and in vitro tests for allergen sensitivity have local nasal allergy, diagnosable by the presence of allergen-specific IgE in their nasal secretions or a positive nasal allergen challenge or both. The pharmaceutical management of allergic rhinitis rests on symptomatic treatment with antihistamines that perhaps are more effectively administered intranasally than orally and intranasal corticosteroids. Allergen immunotherapy is very effective, even for local allergic rhinitis, and the shortcomings of subcutaneous immunotherapy of inconvenience and safety are reduced by the introduction of sublingual immunotherapy (SLIT). Use of the latter is currently somewhat limited by the lack of appropriate dosing information for SLIT liquids and the limited number of allergens for which SLIT tablets are available.
