Without enough functional alpha-1 antitrypsin, neutrophil elastase destroys the small air sacs in the lungs (alveoli) and causes lung disease. Excessive damage to the alveoli leads to emphysema, an irreversible lung disease that causes extreme shortness of breath.ore than 120 mutations in the SERPINA1 gene have been identified. Some of these mutations do not affect the production of alpha-1 antitrypsin, while others cause a shortage (deficiency) of the protein.
The most common causes of exudative pleural effusions are bacterial pneumonia, cancer (with lung cancer, breast cancer, and lymphoma causing approximately 75% of all malignant pleural effusions), viral infection, and pulmonary embolism. Another common cause is after heart surgery.he most common causes of transudative pleural effusions in the United States are biventricular failure, and cirrhosis (causing hepatic hydrothorax). Nephrotic syndrome leading to increased loss of albumin and resultant hypoalbuminemia and reduced colloid osmotic pressure is another, less common, cause.
