bruiseWhat Is Hypoprothrombinemia?

[dropcap]H ypoprothrombinemia is a deficiency of prothrombin (clotting factor II) in the blood that is characterized by impaired hemostasis in response to trauma or a laceration.

Q: What is hemostasis and how is it altered by a deficiency of prothrombin?

A: Hemostasis encompasses the tightly regulated processes of blood clotting, platelet activation, and blood vessel repair.1

Prothrombin is a protein clotting factor present in blood that is involved in the first part of hemostasis, which is blood clotting or coagulation. Vitamin K is required for prothrombin production.

When a laceration or wound is sustained, prothrombin is converted to the enzyme thrombin. Thrombin in turn acts on fibrinogen to convert it to fibrin which then forms the framework of a clot to stop bleeding. Deficiency of prothrombin prevents this series of events and bleeding is not properly stopped.

After the clotting process of hemostasis would come the second part, platelet activation. Eventually, coagulation and platelet activation are switched off by blood-borne inhibitors.

What Is Folic Acid Or Folate Deficiency Anemia?

[dropcap]F[/dropcap]olic acid deficiency anemia, also called folate deficiency anemia, is a macrocytic anemia characterized by defective DNA synthesis of red blood cells that results from a lack of folate in the body.

Q: How does folate deficiency cause anemia?

A: Folates are a family of B vitamins and folic acid is an active form.

Folate is required for the formation of both red and white blood cells in the bone marrow and for their maturation.

Also, folate serves as a carrier in the formation of heme, which contains iron, and is the non-protein part of the hemoglobin molecule.1

Red blood cells provide oxygen to body tissues. When there are not enough red blood cells or when they cannot properly carry oxygen, the condition is called anemia. In folic acid deficiency anemia, the red blood cells are abnormally large. Such cells are called macrocytes (macro size cells). They are also called megaloblasts (mega size cells) as seen in the bone marrow where they are produced. This is why this macrocytic anemia is also called megaloblastic anemia.2

Tests that may be done to determine folate adequacy are complete blood count (CBC), red blood cell folate level, methylmalonic acid level, and homocysteine level. Folic acid deficiency anemia shows a decrease in red blood cell folate and/or serum folate levels and normal plasma methylmalonic acid level with elevated homocysteine blood level. These levels distinguish folic acid deficiency anemia from vitamin B12 deficiency anemia.3
