Pulmonary function and alpha-1-antitrypsin levels in patients after so-called idiopathic spontaneous pneumothorax. 1987

A Pawlowicz, and W Droszcz

The subpleural blebs found in patients with so-called idiopathic spontaneous pneumothorax suggest that pneumothorax could possibly be an early manifestation of pulmonary emphysema in these subjects. In order to investigate this hypothesis, fifty-six young adults (32 +/- 9 yr; 45 men and 11 women) were examined after idiopathic spontaneous pneumothorax. All were apparently healthy with no history of pulmonary disease. Physical and X-ray examination were normal. The episode of pneumothorax was the only sign of lung pathology. A control group of 20 healthy people was also studied. The mean age and smoking habits in the patients and control groups were similar. Only four patients (7%) revealed definite evidence of emphysema, consisting of a reduction of diffusing capacity, decrease of lung recoil pressure and a secondary reduction of forced expiratory flow at 50% of vital capacity. Serum alpha-1-antitrypsin levels in these patients were normal.

UI	MeSH Term	Description	Entries
D008168	Lung	Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.	Lungs
D008170	Lung Compliance	The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung.
