Prothrombin deficiency
Prothrombin Deficiency
Prothrombin deficiency (pronounced pro-throm-bin de-fish-en-see) is a rare blood disorder characterized by a deficiency in the blood clotting protein known as prothrombin.
Etymology
The term "prothrombin" is derived from the Greek words "pro" meaning "before" and "thrombos" meaning "clot". The term "deficiency" comes from the Latin "deficere" meaning "to lack".
Definition
Prothrombin deficiency is a condition in which the body does not produce enough prothrombin, a protein that plays a crucial role in the blood clotting process. This deficiency can lead to excessive bleeding and bruising.
Symptoms
Symptoms of prothrombin deficiency may include easy bruising, prolonged bleeding from minor cuts or injuries, nosebleeds, and in severe cases, life-threatening internal bleeding.
Causes
Prothrombin deficiency is usually inherited, meaning it is passed down through families. It is caused by mutations in the F2 gene, which provides instructions for making prothrombin.
Diagnosis
Diagnosis of prothrombin deficiency typically involves blood tests that measure the amount of prothrombin in the blood and how long it takes for the blood to clot.
Treatment
Treatment for prothrombin deficiency may include blood transfusions, infusions of plasma or prothrombin complex concentrates, and vitamin K supplements.
