December Is National Aplastic Anemia Awareness Month
December Is National Aplastic Anemia Awareness Month What Is Aplastic Anemia? Aplastic anemia is a non-cancerous disease that occurs when the bone marrow stops making enough blood cells. The body makes three types of blood cells: red blood cells, which contain hemoglobin and deliver oxygen to all parts of the body white blood cells, which help fight infection platelets, which help blood clot when you bleed These blood cells are made in the bone marrow, which is the soft, sponge-like material found inside bones. The bone marrow contains immature cells called stem cells that produce blood cells. Stem cells grow into red cells, white cells, and platelets or they can make more stem cells. In patients who have aplastic anemia, there are not enough stem cells in the bone marrow to make enough blood cells. Picture of blood cells maturing from stem cells. Experts believe that aplastic anemia is an autoimmune disorder. This means that the patient’s immune system (which helps fight infection) reacts against the bone marrow and the bone marrow is not able to make blood cells. Stem cells are no longer being replaced and the left over stem cells are not working well. Therefore, the amount of red cells, white cells, and platelets begin to drop. If blood levels drop too low, a person can feel very tired (from low red cells), have bleeding or bruising (from low platelets), and/or have many or severe infections (from low white cells). What Are the Key Statistics About Aplastic Anemia? Aplastic anemia can occur in anyone of any age, race, or gender. -

Secondly, many of the business. The development of anemia may be subtle, and TEC is a diagnosis of exclusion. The broad differential diagnoses of anemia include decreased RBC production (erythropoiesis) or increased RBC destruction (hemolytic anemias). Decreased RBC production includes viral suppression and bone marrow failure (congenital or acquired).

Laboratory Features of Cutaneous Lupus Erythematosus 313
CHAPTER 23 Laboratory Features 23 of Cutaneous Lupus Erythematosus Shuntaro Shinada, Daniel J. Wallace Assuming that patients with cutaneous lupus erythematosus (CLE) do not fulfill the American College of Rheumatology criteria for systemic LE (SLE) (Tan et al. 1982), what laboratory features should the clinician look for? Interestingly, there are several. This chapter attempts to elucidate the laboratory abnormalities associated with CLE, the most common being hematologic (anemia and leukopenia), erythrocyte sedi- mentation rate (ESR), antinuclear antibodies (ANAs), and antiphospholipid anti- bodies. These features are compared with those observed in SLE and certain cuta- neous clinical subsets that have been studied. General Approach to Laboratory Testing When a dermatologist, family practitioner, internist, or rheumatologist first sees a patient with CLE, their principal concern should be to rule out evidence of systemic disease. After all, 15% of patients with CLE progress to SLE in 10–15 years of obser- vation (Rowell 1984). In addition to a complete medical history and physical exami- nation, clinical laboratory findings can be very helpful in this regard. Specifically, a blood chemistry panel allows screening for renal or hepatic involvement. Creatine phosphokinase testing assists in ruling out muscle inflammation. Evidence for autoimmune hemolytic anemia or thrombocytopenia is looked for in the complete blood cell count as well as in the lactic dehydrogenase, reticulocyte count, Coombs’ direct antibody testing, serum haptoglobin, and antiplatelet antibodies. A routine urinalysis free of cellular casts or protein makes it highly unlikely that the kidney is involved. Specific autoantibodies, almost never observed in CLE, if found, can suggest central nervous system disease (antiribosomal P,antineuronal), mixed connective tis- sue disease (anti-RNP), or other disease subsets. -

Diagnosis and Management of Autoimmune Hemolytic Anemia in Patients with Liver and Bowel Disorders

Although the main causes of anemia in these conditions are represented by gastrointestinal bleeding and iron deficiency, autoimmune hemolytic anemia should be considered in the differential diagnosis. Due to the epidemiological association, autoimmune hemolytic anemia should particularly be suspected in patients affected by inflammatory and autoimmune diseases, such as autoimmune or acute viral hepatitis, primary biliary cholangitis, and inflammatory bowel disease. In the presence of biochemical indices of hemolysis, the direct antiglobulin test can detect the presence of warm or cold reacting antibodies, allowing for a prompt treatment. Drug-induced, immune-mediated hemolytic anemia should be ruled out. On the other hand, the choice of treatment should consider possible adverse events related to the underlying conditions. Given the adverse impact of anemia on clinical outcomes, maintaining a high clinical suspicion to reach a prompt diagnosis is the key to establishing an adequate treatment.
