Background:
Allergic Rhinitis (AR) though quite common in India, does not receive its due importance as it deserves.
Aim Of The Study:
To identify the demographic and clinical profile of the patients with AR and to find the association of pre-dominant disease symptoms with common allergens, type and severity of the disease and other co-morbidities.
Settings And Design:
This clinic-based cross-sectional, observational study was conducted among adult patients presenting with signs and symptoms suggestive of AR.
Methods And Material:
Consecutive 548 patients were initially screened for possible cases of AR by proper history taking and physical examination and confirmation was done by a battery of investigations, including modified skin prick test. A total of 462 patients who were finally diagnosed with AR were included in the study. Categorization of these patients was done following Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines. Pulmonary function tests and X-ray/CT-scan of the para-nasal sinuses were done to confirm the presence of bronchial asthma and sinusitis, respectively.
Statistical Analysis Used:
Data were analyzed by Statistical Package for Social Scientists (SPSS version 10). Z-test was applied to compare between two rates, at 5% level of significance.
Results:
Proportion of "blockers" was found to be much higher than that of "sneezers-runners" (64.1% vs. 35.9%). "Blockers" had significantly more sensitization to polyvalent house dust, house dust mites and fungi (p < 0.05), while, "sneezers-runners" had more sensitization to pollens (p < 0.05). Significantly more "blockers" had "moderate/severe persistent" and "mild persistent" types of the disease (p < 0.05), while "mild intermittent" and moderate/severe intermittent" type of disease were significantly more common among "sneezers-runners" (p < 0.05). Both bronchial asthma and sinusitis were significantly more common among the "blockers" (p < 0.05).
Conclusion:
It can be concluded from the present study that the clinical profiles of the two main categories of AR namely "sneezers-runners" and "blockers" were distinct from each other. This knowledge can be useful to physicians at all levels for better management of patients with AR.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
01:20Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
