What is Antithrombin Deficiency?

Antithrombin deficiency occurs when there is not enough antithrombin in the blood, a protein that helps control blood clotting. It can be inherited or acquired, and is associated with an increased risk of forming blood clots in veins. Inherited cases are due to mutations in the SERPINC1 gene, while acquired cases may result from conditions like liver disease or certain medications.

The Role of Antithrombin in the Body

Antithrombin is a natural anticoagulant that inhibits several enzymes involved in the blood clotting process, like thrombin and factor Xa. It requires heparin, a medication, to enhance its activity. Antithrombin's primary role is to prevent blood clots from forming too easily, maintaining normal blood flow in the body.
Antithrombin deficiency is a rare condition characterized by a lack of antithrombin, a protein that controls blood clotting, leading to an increased risk of blood clots. It can be inherited through mutations in the SERPINC1 gene or acquired due to conditions like liver disease.

Symptoms and Diagnosis

Symptoms of antithrombin deficiency may include recurrent blood clots, often in the veins of the legs or lungs. Diagnosis typically involves blood tests to measure antithrombin activity. If levels are low, further genetic testing may be conducted to determine if the deficiency is inherited.

Managing Antithrombin Deficiency

Management focuses on preventing blood clots with anticoagulant medications like warfarin or direct oral anticoagulants. In some cases, antithrombin concentrates may be used, especially during high-risk situations like surgery or pregnancy. Regular monitoring and lifestyle changes can also help manage the condition.

FAQs
