From the second decade of life its natural history is less known.

Behavioral and environmental aspects<\/h3>

Much of the segmentation of smokers, ex-smokers and non-smokers has revealed that the effects of other risk factors on lung function can be hidden.<\/p>

More recent studies conducted on non-smoking PiZZ individuals indicate that exposure to kerosene home heating, agricultural occupations, a history of occupational exposure to respiratory irritants, the presence of wheezing, and recurrent respiratory infections and Pneumonia is associated with significantly more impaired lung function.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Respiratory Volume<\/h3>

In respiratory physiology, the respiratory volume per minute is an important parameter in respiratory medicine, due to its relationship with blood levels of carbon dioxide.
The fall in forced expiratory volume in the first second (FEV 1) in a sample of Alpha patients without replacement therapy (index and non-index cases).<\/strong><\/p>

In all these studies the annual fall in FEV 1 is greater among smokers and is significantly reduced in former smokers 16,20-22.<\/strong><\/p>

On the other hand, it does not manage to match what happens in COPD individuals who are ex-smokers without AATAD, in whom the fall in FEV 1 reaches values similar to those observed in non-smokers (30 ml \/ year).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

At the same time, there are recent studies that indicate the existence of genetic mutations that could modify the natural history of PiZZ subjects.<\/p>

A significant increase in a polymorphism in the endothelial nitric oxide synthase gene (C774T) has been demonstrated in PiZZ individuals with FEV 1 <35% 28.<\/p>

Rodr\u00edguez et al 29<\/strong> found an increase in the frequency of polymorphisms in glutathione S-transferase P1 (GST P1-105Val) in patients with AAT deficiency that, together with age and smoking, would explain 41% of the FEV 1 variability found in these patients.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Tobacco is the key element in the natural history of patients with AAT deficiency.<\/p>

The decline in FEV1 and mortality are directly influenced by the amount of tobacco consumed. Patients who quit smoking are able to reduce the fall in FEV1, but it does not reach the normal levels detected in non-deficient individuals.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
