آلرژن‌های هوایی در تست پوستی بیماران مبتلا به آسم، رینیت آلرژیک، اگزما و کهیر مزمن در ایران

Asthma is a common chronic inflammatory of airways especially in childhood. Clinical manifestations include coughing, wheezing and sometimes dyspnea. Allergic rhinitis (AR) is a common nasal inflammatory disease in the world. Prevalence of AR is 10-40% in different regions of the world. Clinical manifestations of allergic rhinitis are sneezing, pruritus, congestion and rhino rhea. Etiologies of allergic disorders are multifactorial. Many patients with chronic urticaria are concerned about different allergens such as aeroallergens or food allergens that could induce or exacerbate their disease. Aeroallergens have an important role in exacerbation of allergic disorders especially asthma and allergic rhinitis, however, their role is less important in eczema and chronic urticaria. Several studies carried out in Iran using Skin Prick Test (a standard test for diagnosis of aeroallergens) showed involvement of pollens from grasses, weeds and trees in dry and warm climates but mites are more common in humid and warm climates such as north of Iran.
