Background: Fungi are ubiquitous in our environment and they are one of the important causes of allergic diseases. Identification of the most common aeroallergens to which patients are sensitized in a specific area is important in the diagnosis and treatment of allergic rhinitis. Objectives: The purpose of this study was to determine the prevalence of skin reactivity to common fungal allergens and total IgE in patients with allergic rhinitis in Ahvaz city. Patients and Methods:In this cross sectional study, 295 volunteers with the signs and symptoms of allergic diseases who referred to the Khuzestan Jahad Daneshgahi Medical Center in Ahvaz during 2010 were investigated. All patients were subjected to skin prick test (SPT) with common allergenic extracts. Data were analyzed by SPSS-18 software using Chi square test. Results: Seventy subjects, comprising 23.7% of the study group had positive skin test to at least one of the fungal allergens. The prevalence rate of sensitivity to fungal allergens was as follow: Cephalosporin 11.5%; mold mix 9.8%; Penicillium mix 9.5%; Alternaria mix 8.1%; and Aspergillus 5.1%. Mean total IgE in patients with SPT was significantly higher than in patients without any positive skin prick test (251 vs. 125 IU/mL, P = 0.001). There was no statistical difference in the prevalence of sensitization to these allergens between two sexes; whereas, 15-35 age groups had significantly higher rates of allergy to fungal allergens (P = 0.047). Conclusions: Fungal sensitization is a relatively common finding among patients with allergic rhinitis. Elimination or reduction of mold exposure in allergic patients is of special consideration and measures to reduce environmental factors which facilitate mold growth and proliferation are very important.

“…8 However, another study in Iran9 found that dust mite allergy is only positive in 20% of the subjects. 9 On the contrary, Saleh et al 10 found that the allergen with the most positive results is mold. 10 The difference in the dominant allergens can be attributed to the different demographic factors which can influence the types of allergen presence in there.…”

Background: Allergic Rhinitis (AR) is an inflammation condition in nasal mucous because of type 1 hypersensitivity. Skin prick test is one of the diagnostic tests to diagnose AR. Purpose of this study was to know the distribution of skin prick test in AR patients. Methods: This study used retrospective descriptive method as cross sectional design. This study was performed from 1 August to 31 October 2014. This study used medical record as secondary data at Department of Otorhinolaryngology-Head and Neck Surgery of Dr. Hasan Sadikin General Hospital. There were 175 cases which fulfilled the inclusion criteria of the study. The data were then analyzed using computer program. Results: Forty seven cases were positive for house dust (26.8%), 127 cases were positive for dust mite (72.5%), 85 cases were positive for rice pollen (48.5%), 62 cases were positive for maize pollen (35.5%), 56 cases were positive for mixed fungi (32%), 100 cases were positive for cockroach (57.1%), 63 cases were positive for horse dander (36%), 50 cases were positive for cat dander (28.5%), 93 cases were positive for dog dander (53.1%), and 38 cases were positive for chicken feather (21.9%). Conclusions:The most aeroallergen making positive result in skin prick test is dust mite.

Background: Fungal spores are ubiquitous constituents indoors and outdoors and are now generally identified as important causes of respiratory allergies. Objectives: This study aims to evaluate the frequency and prevalence of allergens with fungal origin at homes of allergic patients with respiratory symptoms in the city of Mashhad, Iran. Methods: In this cross-sectional study, a group of patients with allergic rhinitis (n = 50) were selected based on positive skin prick test. Healthy volunteers with no respiratory allergy were included in control group with the same age as diseased group. Samples from nasal cavity and different parts of bedroom were collected and cultured. The fungal agents were recognized by conventional mycological methods based on the cultural and microscopic appearance as properties. Results: Colonization with fungi was obtained in 26% -64% and 86-98% of the patient and healthy groups, respectively. Among all species isolated from specimens of the patients, A.flavus was dominant which followed by A. niger, Penicillium and Cladosporium whereas the most commonly isolated fungi from the whole specimens of healthy subjects were A. flavus, A. fumigatus, A. niger, Penicillium, Yeast, Alternaria and Cladosporium. Conclusions: Fungi can be hazardous for health. Furthermore, prevention of fungal spores' growth is important, and also identifying and determining the most common allergen fungi are key steps to provide the necessary recommendations to the patients in controlling and preventing disease.

Skin prick test reactivity to common aeroallergens among allergic rhinitis patients in Iran

Abstract: Our work showed the importance of weeds, especially the Amaranthaceae and Chenopodiaceae families. Diagnosis of pollen allergy can be simplified by using a combination of a few common aeroallergens.
