Thrombin inhibitors in women on oral contraceptives

Progressive antithrombin activity and the immunological levels of antithrombin III, alpha 2-macroglobulin, and alpha 1-antitrypsin were measured in women at various intervals during treatment with oral contraceptives and in a group of untreated women. No significant changes were observed in any of the above parameters. In both control and treated women, there was a positive statistical correlation between progressive antithrombin activity and antithrombin III immunological levels, whereas no correlation was found between the former and alpha 1-antitrypsin or alpha 2-macroglobulin immunological levels. This study questions the possibility of thrombin inhibitors being selective signs of hypercoagulability during treatment with oral contraceptives.

[Studies on the risk factors of arteriosclerosis in a health district region of Lombardy]

Atherosclerosis risk factor, 8,5% two, 2,7% three and 0,6% four.rs have been investigated in 194 males and 135 female, 25 years old. Elevated lipids were found in 7,3% of the sample; "labile" and stable hypertension in 2,7%; diabetes mellitus in 2,7% and overweight in 19%. 19% of the subjects smoked more than 20 cigarettes daily. Prevalence of hyperlipemia and electrocardiographic changes was higher among people in the lower socioeconomic classes. Taking into consideration hyperlipidemia, hypertension, cigarette smoking, overweight and diabetes mellitus as risk factors, 25% exhibited one risk factor, 8.5% two, 2.7% three and 0.6% four.
