Two groups of patients were selected according to their plasma levels of alpha-1-antitrypsin deficiency from among 58 patients with a chronic bronchopathy. Group I had normal plasma levels of alpha-1-antytrypsin; group II had plasma values lower than normal. The pathologic conditions associated with chronic bronchopathies were studied in both groups and so were the gasometric characteristics of the same. Chronic bronchopathies in subjects belonging to group II showed a clear tendency to present normal levels of pCO2 and hydrogen ions possibly related to a greater bronchial impairment in these patients. Independently of the genetic characteristics of plasma alpha-1-antitrypsin deficiency, its general levels are the real indication of its possible etiopathogenic action. Patients with recurrent plasma alpha-1-antitrypsin deficiency, its general levels are the real indication of its possible etiopathogenic action. Patients with recurrent plasma alpha-1-antitrypsin deficiency are more susceptible to bacterial infections, liver cirrhosis, diabetes, and allergic states. All this would be related to the protective effect of this protein fraction, and its reduction according to the most recognized theories would decrease the resistance of hepatic and pancreatic cells.
In a 55 years old male patient bronchoscopy was carried out because of suspected bronchial carcinoma. Chest X-ray showed a lesion in the periphery of left lung, an episode of hemoptysis was reported 4 weeks prior to the examination. During bronchoscopy we found numerous small tumours on the mucosa of distal trachea and left main bronchus. The findings suggested a widespread malignant process, whereas histological examination of biopsies showed tracheobronchopathia osteochondroplastica. In the case described we could not find amyloidosis of tracheal wall or disorders in somatotropine secretion. Pathogenesis and clinical features of the disease, which is in a high percentage detected by chance or post mortem, are discussed.
The Authors have tested serum levels of alpha-1-antitrypsin (A1AT), phosphohexose-isomerase (GPI) and carcinoembryonic antigen (CEA) in 133 patients affected with primary lung cancer, not treated with any drug, and in 183 patients affected with not neoplastic lung diseases or healthy, to control the utility of these markers in the early diagnosis of lung cancer. In many patients all the tests have been made at the same time. The three tumoral markers have been also examined in connection with the histological kinds of lung cancer. Results show that is suitable to test GIP and A1AT at the same time because they are percentually more pathological; serum levels of CEA, that are not very elevated in the pathological cases, seem in correlation with the histological kind of cancer.
