Procam Foundation is working towards providing financial and moral assistance to underprivileged patients of Blood Disorders for their treatment. A blood cell disorder is a condition in which there’s a problem with your red blood cells, white blood cells, or the smaller circulating cells called platelets, which are critical for clot formation. All three cell types form in the bone marrow, which is the soft tissue inside your bones. Red blood cells transport oxygen to your body’s organs and tissues. White blood cells help your body fight infections. Platelets help your blood to clot. Blood cell disorders impair the formation and function of one or more of these types of blood cells. The following are the types of disorders:
Red blood cell disorders
Red blood cell disorders affect the body’s red blood cells. These are cells in your blood that carry oxygen from your lungs to the rest of your body. There are a variety of these disorders, which can affect both children and adults.
Anemia is one type of red blood cell disorder. A lack of the mineral iron in your blood commonly causes this disorder. Your body needs iron to produce the protein hemoglobin, which helps your red blood cells (RBCs) carry oxygen from your lungs to the rest of your body. There are many types of anemia.
- Iron deficiency anemia: Iron deficiency anemia occurs when your body does not have enough iron. You may feel tired and short of breath because your RBCs are not carrying enough oxygen to your lungs. Iron supplementation usually cures this type of anemia.
- Pernicious anemia: Pernicious anemia is an autoimmune condition in which your body is unable to absorb sufficient amounts of vitamin B-12. This results in a low number of RBCs. It is called “pernicious,” meaning dangerous, because it used to be untreatable and often fatal. Now, B-12 injections usually cure this type of anemia.
- Aplastic anemia: Aplastic anemia is a rare but serious condition in which your bone marrow stops making enough new blood cells. It can occur suddenly or slowly, and at any age. It can leave you feeling tired and unable to fight off infections or uncontrolled bleeding.
- Autoimmune hemolytic anemia (AHA): Autoimmune hemolytic anemia (AHA) causes your immune system to destroy your red blood cells faster than your body can replace them. This results in you having too few RBCs.
- Sickle cell anemia: Sickle cell anemia (SCA) is a type of anemia that draws its name from the unusual sickle shape of the affected red blood cells. Due to a genetic mutation, the red blood cells of people with sickle cell anemia contain abnormal hemoglobin molecules, which leave them rigid and curved. The sickle-shaped red blood cells can’t carry as much oxygen to your tissues as normal red blood cells can. They may also become stuck in your blood vessels, blocking blood flow to your organs.
Thalassemia is a group of inherited blood disorders. These disorders are caused by genetic mutations that prevent the normal production of hemoglobin. When red blood cells do not have enough hemoglobin, oxygen doesn’t get to all parts of the body. Organs then do not function properly. These disorders can result in:
- bone deformities
- enlarged spleen
- heart problems
- growth and developmental delays in children
Polycythemia is a blood cancer caused by a gene mutation. If you have polycythemia, your bone marrow makes too many red blood cells. This causes your blood to thicken and flow more slowly, putting you at risk for blood clots that can cause heart attacks or strokes. There is no known cure. Treatment involves phlebotomy, or removing blood from your veins, and medication.
White blood cell disorders
White blood cells (leukocytes) help defend the body against infection and foreign substances. White blood cell disorders can affect your body’s immune response and your body’s ability to fight off infection. These disorders can affect both adults and children.
Lymphoma is a blood cancer that occurs in the body’s lymphatic system. Your white blood cells change and grow out of control. Hodgkin’s lymphoma and non-Hodgkin’s lymphoma are the two major types of lymphoma.
Leukemia is blood cancer in which malignant white blood cells multiply inside your body’s bone marrow. Leukemia may be either acute or chronic. Chronic leukemia advances more slowly.
Myelodysplastic syndrome (MDS)
Myelodysplastic syndrome (MDS) is a condition affecting the white blood cells in your bone marrow. The body produces too many immature cells, called blasts. The blasts multiply and crowd out the mature and healthy cells. Myelodysplastic syndrome may progress either slowly or quite fast. It sometimes leads to leukemia.
Blood platelets are the first responders when you have a cut or other injury. They gather at the site of the injury, creating a temporary plug to stop blood loss. If you have a platelet disorder, your blood has one of three abnormalities:
- Not enough platelets. Having too few platelets is quite dangerous because even a small injury can cause serious blood loss.
- Too many platelets. If you have too many platelets in your blood, blood clots can form and block a major artery, causing a stroke or heart attack.
- Platelets that don’t clot correctly. Sometimes, deformed platelets can’t stick to other blood cells or the walls of your blood vessels, and so can’t clot properly. This can also lead to a dangerous loss of blood.
Platelet disorders are primarily genetic, meaning they are inherited. Some of these disorders include:
Von Willebrand disease
Von Willebrand disease is the most common inherited bleeding disorder. It is caused by a deficiency of a protein that helps your blood clot, called von Willebrand factor (VWF).
Hemophilia is probably the best-known blood clotting disorder. It occurs almost always in males. The most serious complication of hemophilia is excessive and prolonged bleeding. This bleeding can be either inside or outside your body. The bleeding can start for no apparent reason. Treatment involves a hormone called desmopressin for mild type A, which can promote release of more of the reduced clotting factor, and infusions of blood or plasma for types B and C.
Primary thrombocythemia is a rare disorder that can lead to increased blood clotting. This puts you at higher risk for stroke or heart attack. The disorder occurs when your bone marrow produces too many platelets.
Acquired platelet function disorders
Certain drugs and medical conditions can also affect the functioning of platelets. Be sure to coordinate all your medications with your doctor, even over-the-counter ones you choose yourself. The Canadian Hemophilia Association (CHA) warns that the following common drugs may affect platelets, especially if taken long-term.
- nonsteroidal anti-inflammatory (NSAIDs)
- some antibiotics
- heart drugs
- blood thinners
Plasma cell disorders
There are a large variety of disorders that affect the plasma cells, the type of white blood cells in your body that make antibodies. These cells are very important to your body’s ability to ward off infection and disease.
Plasma cell myeloma
Plasma cell myeloma is a rare blood cancer that develops in the plasma cells in the bone marrow. Malignant plasma cells accumulate in the bone marrow and form tumors called plasmacytomas, generally in bones such as the spine, hips, or ribs. The abnormal plasma cells produce abnormal antibodies called monoclonal (M) proteins. These proteins build up in the bone marrow, crowding out the healthy proteins. This can lead to thickened blood and kidney damage. The cause of plasma cell myeloma is unknown.
