[Activity of alpha 1-antitrypsin in blood of patients operated on for tumor and benign hyperplasia of the prostate].

The activity of alpha 1-antitrypsin in the blood of the patients with prostatic carcinoma and benign prostatic hyperplasia before and after the operation was examined. It was observed an increase of alpha 1-antitrypsin in the blood of patients with prostatic carcinoma and benign prostatic hyperplasia after the operation. In the blood patients of control group an increase of alpha 1-antitrypsin was observed too. The activity of alpha 1-antitrypsin in prostatic carcinoma was the highest during the whole observation period. The similar increase of the activity of alpha 1-antitrypsin after the operation in the blood of all groups of patients is connected with inflammatory reaction. The highest activity of alpha 1-antitrypsin in the blood of patients with prostatic carcinoma is the proof that the malignant neoplasm is associated with much more inflammatory reaction and the further hormonal treatment can be connected with a risk of thromboembolic complications.
