“…On comparing these findings with a study carried out in Central India (Nagpur), the most common allergen was mite (49%), followed by pollen (21.8%), dust (15.4%), insect (10.6%), fungus (3%), and animal epithelia (0) in AR patients. 17 In Lucknow, the most common offending allergen was insects (21.2%), followed by dusts (12.0%), pollens (7.8%), animal dander (3.1%), and fungi (1.3%). 18,19 A study from North India also showed markedly positive skin reactions to antigenic extracts of 13 pollens, varying from 2.4% to 16.9%, with an average of 9.65%.…”

Introduction: Allergic diseases are common and they have increased in frequency over the last few decades. More than 30% of the population suffers from allergic rhinitis (AR). It is defined as a combination of two or more symptoms, namely, watery rhinorrhea, nasal obstruction, itching, and sneezing. Allergic rhinitis occurs when these symptoms are the result of immunoglobulin E (IgE)-mediated inflammation following exposure to allergens. The common inhalant allergens causing AR are house dust mites, pollens, fungi, and insects. Skin prick test (SPT) is the gold standard test in the diagnosis of AR. Aim: To study the distribution of inhalant allergens in AR and to find out seasonal variations in allergens by SPT. Materials and methods: A descriptive study was done in 120 patients who came with symptoms of AR to ear, nose, and throat (ENT) outpatient department (OPD) of tertiary care hospital. The study was done from November 2017 to October 2018. The patient was clinically evaluated and the SPT was performed to analyze the distribution of inhalant allergens and its seasonal variations. Results: The majority of the patients are males between 21 and 30 years of age. Majority of the people are urban residents. Dust mites followed by pollens yielded the highest number of positive responses among inhalant allergens. Dust mites and dusts are more common during winter season, pollens are more common during summer season, and fungi and insects (5.83%) during rainy season. Conclusion:Analyzing the distribution of specific allergens for a particular geographical area and its seasonal variation helps in appropriate diagnostic evaluation of allergens, educating the patient on what allergen to avoid and also to find the best formulation of allergen immunotherapy for effective AR treatment.

“…In Western region, Parthenium hysterophorus , Cynodon dactylon , Ipomoea sp., Holoptelea integrifolia , Cassia sp., Ischaemum sp. etc were the dominant allergens from Nagpur (Maharashtra) 54 . In Amravati (Maharashtra), major pollen grains reported were Moringa oleifera , Delonix regia , Tecoma stans and Parthenium hysterophorus 55 .…”

Allergic diseases such as bronchial asthma, rhinitis and eczema are an important public health issue globally in 21st century. Their prevalence and impact in India is high, in terms of total numbers of people affected. Due to diverse climate and lifestyle, the Indian population is exposed to a rich and varied range of aerobiological particles. In the last two decades in India, 83 pollens, 34 fungi, six dust mite and 19 insect species were reported as allergenic, often contributing to heavy allergenic exposure in indoor and outdoor environments. There are currently few practitioners who offer allergy diagnosis and treatment in India, but there is active basic and molecular research aiming to improve the health of allergic patients. This review explores the field of aero-allergy in India during the last two decades, with special emphasis on prevalence across various centres and relevant scientific advances such as genetic associations and new therapeutics. This review will be helpful for clinicians to select aero-allergens for sensitisation testing in patients suffering from symptoms in different regions of India, and to support patients undertaking prophylaxis of allergic symptoms in India according to local environmental conditions. This study also helps to define patient selection for allergy testing and the role of test results in guiding allergic disease management in the Indian context. Finally, we summarize genetic findings relevant to aero-allergy in India and discuss the development of novel therapeutics for investigation and management of aero-allergy in India.
