Allergic Rhinitis (AR)

Background Allergic Rhinitis is a chronic Th2-mediated inflammatory disorder associated with significant disease burden and impaired quality of life. Emerging evidence highlights the role of the gut-immune axis, intestinal permeability, and microbial-metabolic signaling in modulation of allergic immune responses. In , Agni is considered the fundamental regulator of digestion, metabolism, and physiological homeostasis. Disturbance in Agni may contribute to altered gut homeostasis and immune dysregulation. However, the relationship between Agni, gut permeability-associated mechanisms, and Th2-mediated immune response in allergic rhinitis remains insufficiently explored. Aim To evaluate the effect of an Agni-modulating Ayurvedic intervention on Th2-mediated immune response and gut permeability-associated mechanisms in individuals with allergic rhinitis. Objectives The primary objective is to evaluate the effect of an Agni-modulating Ayurvedic intervention on serum immunoglobulin E (IgE) and interleukin-4 (IL-4) levels in allergic rhinitis. Secondary objectives include assessment of gut permeability-associated biomarkers including serum zonulin and lactulose-mannitol test parameters, evaluation of changes in Agni status and clinical symptom severity, and exploration of associations between Agni status, gut permeability-associated biomarkers, and immune response. The study also aims to explore inter-individual variability based on Agni types and Prakriti. Methods This study is designed as a randomized, controlled, assessor-blinded, parallel-group clinical trial with an embedded exploratory mechanistic component. A total of 104 participants aged 18-60 years diagnosed with allergic rhinitis based on standard clinical criteria and positive skin prick test will be recruited and randomized in a 1:1 ratio into intervention and control groups. The intervention group will receive a standardized Agni-modulating Ayurvedic treatment protocol consisting of Deepana-Pachana formulations followed by Amrita Ghritham along with Pathya-Apathya advice, in addition to standard conventional management. The control group will receive standard conventional management. Primary outcome measures include serum IgE, IL-4, serum zonulin, and lactulose-mannitol test parameters. Secondary outcomes include Agni assessment, Total Nasal Symptom Score (TNSS), eosinophil count, and subgroup analysis based on Agni and Prakriti. Expected Outcome The study is expected to provide preliminary evidence regarding the relationship between Agni modulation, gut permeability-associated mechanisms, and Th2-mediated immune response in allergic rhinitis, and may contribute to biomarker-oriented translational and integrative approaches in allergic disease management.

Allergic rhinitis is a very common condition that can cause symptoms such as sneezing, a runny nose, nasal blockage, and itching in the nose. These symptoms can interfere with sleep, daily activities, and overall quality of life. Although several medicines are available to treat allergic rhinitis, it is not always clear which combination of treatments works best for patients in everyday clinical practice. The purpose of this study is to compare two commonly used treatment combinations for allergic rhinitis in adults. One group of participants will receive an intranasal corticosteroid along with an oral antihistamine. The other group will receive an intranasal corticosteroid along with an oral antileukotriene. Both treatment approaches aim to reduce inflammation and improve symptoms, but they act through different pathways in the body. This study is designed as a randomized controlled trial. Participants who meet the eligibility criteria will be assigned by chance to one of the two treatment groups. This method helps ensure that the comparison between treatments is fair and unbiased. The main goal of the study is to find out whether one treatment combination provides better relief of nasal symptoms than the other, or if both treatments are equally effective. To assess this, participants' symptoms will be recorded using a structured symptom scoring system at the start of the study and during follow-up visits. Participants will be evaluated at baseline and at scheduled follow-up visits. Changes in their symptoms over time will be carefully monitored and compared between the two groups. The results of this study may help doctors choose the most effective treatment approach for adults with allergic rhinitis and support better evidence-based care. This study has been reviewed and approved by the institutional ethical review committee. Participation in the study is voluntary, and informed consent will be obtained from all participants before enrollment.

The goal of this clinical trial is to learn if taking probiotics, vitamin D, or both together can help lower symptoms of allergic rhinitis (AR) and improve quality of life in adults. Allergic rhinitis is a condition that causes sneezing, nasal congestion, and itchy or watery eyes. The main questions this study aims to answer are: • Do these supplements improve the quality of life for people with AR? Researchers will compare four groups: * People taking probiotics and vitamin D * People receiving standard treatment only (control group) Participants will: * Take a probiotic capsule daily and/or a vitamin D tablet (based on blood levels) for 12 weeks * Continue standard allergic rhinitis treatment (like antihistamines or nasal sprays) * Visit the clinic for checkups and lab tests * Complete surveys about their symptoms and quality of life This study will help researchers understand if adding probiotics and/or vitamin D to standard care can help people with allergic rhinitis feel better.

The clinical trial aims to investigate the efficacy of Lactobacillus rhamnosus LRa05 in alleviating allergic rhinitis and its impact on the gut microbiota among 70 pediatric participants aged 4-12. The primary objective is to validate the improvement in allergic rhinitis symptoms following an 8-week intervention with Lactobacillus rhamnosus LRa05. Participants were instructed to consume the probiotic powder daily for approximately 8 weeks. At baseline, week 4, and week 8 endpoints, assessments of nasal symptoms, quality of life questionnaires, and stool samples for microbiota analysis were conducted on the participants, and blood samples were collected for immune-related factor testing.
