HDM allergy is highly prevalent and can manifest in the respiratory system as allergic rhinitis, allergic asthma, or both but should be thought of as one common condition affecting the whole respiratory tract. Although mite populations are constrained by humidity, the adaptive spread of the HDM, overlapping as it does with human habitation, suggests that it thrives in preferred human living conditions. Therefore controlling exposure is challenging. Studies indicate that HDM allergen levels should be maintained at less than 2 μg/g to decrease the likelihood of sensitization; however, measures to decrease HDM exposure have shown little or no benefit on symptoms in sensitized subjects.
HDM allergens are unusually potent and able to activate both the adaptive and innate immune systems. The exact pathways vary according to allergen group, and elucidating these offers could be an exciting new avenue of future research for understanding HDM This study obtained vital statistics from the Ministry of Health and Welfare, hourly meteorological records from the Central Weather Bureau, and hourly air pollution monitoring records from the Environmental Protection Administration (EPA) for Metropolitan Taipei from 2000 to 2008. Metropolitan Taipei, located in Northern Taiwan, has approximately 6.2 million residents or 27.9% of the national population in 2000.Death causes were coded according to the diagnoses of the 9th revision of International Classification of Diseases (ICD-9). Death records for all causes [excluding injuries and external causes (ICD-9 CM 800-999)], circulatory diseases (ICD-9 CM 390-459), and respiratory diseases (ICD-9 CM 460-519) were retrieved.
