Cough is a common symptom of patients who visit a clinic. Chronic cough lasts more than 8 weeks and the most common causes are closely related to allergic diseases such as upper airway cough syndrome due to rhinosinusitis, asthma, nonasthmatic eosinophilic bronchitis, and gastroesophageal disease. This issue of AP Allergy features important aspect of cough hypersensitivity in chronic cough [1]. Genetic regulation is a key phenomenon in understanding of life science. The interaction of environment and genetic regulation, in other words, epigenetic regulation in allergic diseases is reviewed in this issue [2]. Airway remodeling, a critical component in the management of asthma, and its relationship with mechanical force was reviewed as well [3]. Drug hypersensitivity can be related with some of viral infections such as human immunodeficiency virus (HIV) infection. As a matter of fact, antiviral drugs can result in drug hypersensitivity. Drug hypersensitivity in HIV-infected patients is also featured in this issue [4].
