The abundant serum protein alpha-1 antitrypsin (AAT) is the prototype chronic obstructive pulmonary disease (COPD) biomarker. AAT is an antiprotease which inhibits neutrophilderived proteases and protects the fragile tissues of the lung. Absence of this key antiprotease renders ...
In the setting of asthma early emphysema due to alpha1-antitrypsin deficiency (alpha1-ATD) is an unusual and frequently missed diagnosis
遗传背景(特应症、α-1抗胰蛋白酶数值等) 肺功能检查很重要 COPD有这样的症状特征: 1,慢性的咳嗽、咳痰 2,活动后胸闷、喘息 3,某些诱因可诱发上述症状加重 但是,必须要小心特定病因类疾病。比如 α-1抗胰蛋白酶缺乏症(alpha-1 antitrypsin deficiency, AATD) 弥漫性泛细支气管炎(diffuse panbronchiolitis, DPB...
COPD 慢性阻塞性肺病 Chronic obstructive pulmonary disease (COPD) is airflow limitation caused by an inflammatory response to inhaled toxins, often cigarette smoke. Alpha-1 antitrypsin deficiency and various occupational exposures are less common causes in nonsmokers. Sy...
“It took me 21 years for a correct diagnosis of AATD. I am finishing my seventh year of infusions and have never missed one. I am on my feet and moving most of the time.” —MatteoItaly, alpha1-antitrypsin deficiency 1de Serres F, Blanco I. Role of alpha-1 antitrypsin in human he...
Deficiency of alpha-1 antitrypsin increases the risk of developing COPD and other conditions that affect a range of bodily systems. 3.只有老年人才会患上COPD 3. Only older adults develop COPD COPD在老年人中当然比在年轻人中更常见,但年轻人并不能对这种疾病免疫。
在少数人群中,有一种罕见的遗传风险因素导致肺气肿。这些人缺乏α - 1抗胰蛋白酶。他们的肺难以保护肺泡所受到的各种损伤。COPD可以在家庭中流行。 In a small number of people, a rare genetic risk factor causes emphysema. These people lack alpha-1 antitrypsin. Their lungs are less able to protect ag...

缺乏α1-抗胰蛋白酶(alpha-1 antitrypsin ,AAT,又称甲型抗胰蛋白酵素)α1-抗胰蛋白酶(AAT)是由肝脏制造,为体内重要的蛋白酶抑制素(Protease inhibitor),可与许多蛋白酶结合抑制其活性,防止蛋白酶的过度作用。 持续出现慢性阻塞性肺病的症状。 慢性阻塞性肺病突然发作前会出现一些征兆,若提早察觉,可以提早防范或...
The most common cause of COPD is tobacco smoking. Other risk factors include indoor and outdoor air pollution including dust, exposure to occupational irritants such as dust from grains, cadmium dust or fumes, and genetics, such as alpha-1...
