• Autoimmune Condition, Especially Combined With Smoking And Oral Contraceptive Use, Massively Increases Risk Of Stroke And Heart Attack In Young Women 

The autoimmune condition antiphospholipid syndrome mainly affects young women. An Article published Online First and in the November edition of The Lancet Neurology shows that women with a particular subtype of antibody called lupus anticoagulant (LA) have a more than 40-fold increased risk of stroke and 5-fold increased risk of heart attack compared with the general population (of young women). Smoking and oral contraceptive use increase the risk of these events even more. The Article is written by Dr Rolf Urbanus and Dr Philip de Groot, University Medical Centre Utrecht, Netherlands, together with colleagues from the Leiden University Medical Centre.

Antiphospholipid syndrome occurs when autoantibodies* bind to cell membranes, interfering with the regular clotting mechanism of the blood. Diagnosis occurs when young women (under 50 years) suffer a thrombotic event such as a stroke or heart attack, and antiphospholipid antibodies are tested. Although it is known that this condition causes thrombosis, bleeding, and repeat miscarriage in women, the extent of the increased risk for stroke and heart attack was unknown before this study. . . .

In an accompanying Reflection and Reaction, Dr Kathryn Kirchoff-Torres and Dr Steven R Levine, Stroke Center, Mount Sinai School of Medicine, New York, NY, USA, say that the most important aspect of the study is its conclusion that young women with LA need to be warned about the dangers of smoking and use of oral contraceptives.
