Blood Disorders BLOOD DISORDERS – THREE CASE STUDIES Blood Disorders, Resources: Ch. 8 of Human Diseases: Three Patient Case Studies Author Author Affiliation 1 Blood Disorders 2 Abstract This paper examines the presenting histories and symptoms of 3 patients with potential blood disorders. For each case the author identifies the blood disorder each of the 3 patients are at risk for. The identification of blood disorders is based on upon symptoms, lifestyle, and/or family history. Included is a description of the cause of the disorder, how it can be diagnosed, what can be done to treat it, and how to prevent it in the future. Blood Disorders 3 Blood Disorders, Resources: Ch. 8 of Human Diseases: Three Patient Case Studies Three patients have presented with varying histories and symptoms indicative of being at risk for certain blood disorders. Although the symptoms of blood disorders can be vague and nonspecific, when combined with a patient history and lifestyle, a working differential diagnosis is possible. Such groups of histories/symptoms sometimes relate to a decrease in blood cells, such as a reduced number of red blood cells (anemia), a reduced number of white blood cells (leukopenia), or a reduced number of platelets (thrombocytopenia). This paper examines the presenting histories and symptoms of 3 such patients with potential blood disorders. For each case the author identifies the blood disorder that each of the 3 patients are at risk for. The identification of the blood disorder is based on upon symptoms, lifestyle, and/or family history. Included is a description of the cause of the disorder, how it can be diagnosed, what can be done to treat it, and how to prevent it in the future. (The Merck Manual of Medical Information, 2nd Home Edition) Case Study Amy Presenting History Amy, a 4-year-old Caucasian female, has been complaining of being tired all the time. She is pale and a picky eater. Her mother is a single mom with a small budget to feed a large family. Amy only eats pasta, breads, and hot dogs, and drinks only artificial fruit punch. Diagnosis (symptoms, lifestyle and/or family history) Amy’s subjective symptom of “being tired all the time” and her pale skin tone suggest that she may have anemia. This would be consistent with a lifestyle reported as “picky eater.” In Blood Disorders 4 addition, the lifestyle eating habits of eating food low in iron would point to an iron deficiency resulting in anemia. On the other hand, depending upon the types of pasta, bread and hot dogs eaten, Amy should be getting sufficient iron in her diet. However, the hot dogs could actually be “veggie” dogs and the bread/pasta may not be whole grains. Blood work would be needed to confirm the diagnosis. Again, the diagnosis of anemia is consistent with the family history of a single mom, small budget and large family. This history is suggestive of a risk of nutritional deficiency leading to anemia. With this presentation additional diagnostic work-up would be the most prudent. Causes Anemia in children is usually caused by having an iron deficiency. The low iron in the body causes blood counts to be low and can cause a child to feel tired, have pale skin, and be irritable and weak. Left untreated it can lead to many problems, including learning disabilities and behavior problems. The most common cause of iron deficiency is having a diet that doesn't have enough iron in it. This can be caused by not eating foods that are rich in iron. Treatment Anemia should be treated with oral iron supplements in the form of ferrous sulfate. Vitamin C can also increase absorption and is needed for the production of hemoglobin. Ironrich foods include raisins, meats (liver is the highest source), fish, poultry, egg yolks, legumes (peas and beans), and whole-grain bread is the best natural treatment for anemia. Consideration should be given to talking with the mother about nutrition classes and/or an introduction to appropriate social services that might be available to the family. Prevention Diet is the most important way to prevent and treat iron deficiency. Blood Disorders 5 Case Study Marcus Presenting History Marcus is a 5-year-old African-American male who has just moved to New York City, and is visiting his new pediatrician for a kindergarten physical. His mom tells the nurse that she carries the “trait” and wants Marcus screened for it. Diagnosis (symptoms, lifestyle and/or family history) Marcus should be evaluated for Sickle trait and/or Sickle cell anemia. People who inherit a sickle cell gene from one parent and a normal gene from the other parent have a condition called sickle cell trait. The mother states that she does have the trait. Sickle cell trait is different from sickle cell anemia. People who have sickle cell trait don’t have the disease, but they have one of the genes that cause it. Sickle cell anemia is a serious disease in which the body makes sickle-shaped red blood cells. Marcus is at risk for both and should fully evaluated. Causes Sickle cell anemia is an inherited, lifelong disease. People who have the disease are born with it. They inherit two copies of the sickle cell gene—one from each parent. People who inherit a sickle cell gene from one parent and a normal gene from the other parent have a condition called sickle cell trait. Sickle cell trait is different from sickle cell anemia. People who have sickle cell trait don’t have the disease, but they have one of the genes that cause it. Like people who have sickle cell anemia, people who have sickle cell trait can pass the gene to their children. Treatment People with sickle cell trait usually have no symptoms and need no treatment. (The Sickle Cell Information Center) Blood Disorders 6 Prevention Case Study Richard Presenting History Richard has noted over the past several weeks that he is having more bruises, or ecchymosis, all over his body. After coughing this morning, he noticed tiny red marks all around his eyes. Diagnosis (symptoms, lifestyle and/or family history) Thrombocytopenia An abnormally small number of platelets, or hrombocytopenia, result from conditions that either impair production, increase destruction, or cause sequestration of platelets. Regardless of cause, prolonged bleeding results from minor and major trauma. Spontaneous hemorrhages are often-visible on the skin as small, flat, red spots called petechiae, or as larger purplish patches called ecchymosis. Spontaneous hemorrhages may also occur in the mucous membranes of the mouth and internal organs. Suppression of the bone marrow by certain medications or cancer may diminish platelet production. Autoimmune disorders may increase platelet destruction or impair platelet function. Massive blood transfusions dilute circulating platelets and decrease platelet viability. Thrombocytopenia can usually be corrected by treating the underlying cause. Preventative measures such as bedrest to avoid accidental trauma are highly recommended until platelet counts increase to acceptable levels. Platelet transfusions are reserved for severe thrombocytopenia or in cases of severe bleeding. Primary Thrombycythemia Primary thrombocythemia is a marked increase in circulating platelets due to unknown causes. Primary thrombocythemia occurs most frequently in adult men and women during the sixth or seventh decade of life. Symptoms are related to abnormal platelet function and thrombosis. Blood Disorders 7 Thrombosis causes ischemia to the central nervous system, the peripheral extremities, and vital organs of the body. Symptoms include dizziness, visual problems, headaches, difficulty breathing, and extreme pain in the extremities. Bleeding may result in some cases due to abnormal platelet function.
