Study of the therapeutic management of pollen allergy and assessment of quality of life of patients at Bengaluru Allergy Centre

Abstract

Abstract INTRODUCTION: Pollen is one of the most common triggers of an allergy or hay fever. It is a fine yellowish powder that fertilizes other plants and is carried by the wind, birds, insects, or other animals. Between 10% and 40% of the Indian population has a pollen allergy which makes it one of the most common outdoor allergies in the country. In Bengaluru, 20% of allergies are caused by pollens – Parthenium, Amaranthus spinosus, Prosopis juliflora, and Ricinus communis. AIMS: The aim was to study the therapeutic management of patients who are allergic to pollen at Bengaluru Allergy Centre and assessment of the quality of life (QOL) of patients. SETTINGS AND DESIGN: It was a prospective, interventional study conducted at Bengaluru Allergy Centre. SUBJECTS AND METHODS: Both male and female patients who have had chronic allergic rhinitis (CH AR) and also CH AR with other comorbidities and who have been taking treatment for more than 6 months are involved. The data were collected from case records of patients in the data collection form. Questionnaires were used to assess the QOL, and counseling was done to the pollen allergy patients. STATISTICAL ANALYSIS: A paired t-test was done using SPSS software for analyzing the P value, simple descriptive graphs, and pie charts, and the percentage was calculated. RESULTS: A total of 60 patients were enrolled in the study where 26 were male and 34 were female. The maximum number of patients was affected with weed pollen. Cynodon dactylon (13.97%) is the major sensitivity seen in patients. Sneezing, running nose, and itchy eyes are commonly seen in patients with AR due to pollens. The classification of AR with other comorbidities is CH AR (78.33%), CH AR + ANB (10%), CH AR + urticaria (6.66%), and CH AR + AD (5%). Patients’ symptoms were persistent at day (5%), night (8.33%), and both day and night (86.66%), whereas symptom severity in Bengaluru amounted to 41.66%, other than Bengaluru 16.66%, and both in and out of Bengaluru 41.66%. In Bengaluru Allergy Centre (BAC), the main treatment given is sublingual immunotherapy, nasal spray, vitamin supplements, pre- and probiotics, and influenza vaccine. Nasal and eye symptoms are commonly seen in patients with AR due to pollen, and QOL factors that significantly impacted were productivity at home/work, mental concentration, reading books or newspapers, outdoor life (e.g., sports and picnics), going out, visiting friends or relatives, sleeping, and tiredness. A decrease in the symptoms and an increase in the QOL were achieved by proper patient counseling and treatment. There is a significant reduction in symptom scores after the intervention. The intervention has a significant effect in reducing the symptom scores (t = 17.99, P < 0.001). CONCLUSIONS: It can be concluded that intervention by clinical pharmacists by way of patient counseling can help improve the reduction of symptoms and QOL of patients.
