Paroxysmal nocturnal hemoglobinuria (PNH): An acquired blood disease where the immune system attacks red cells due to a mutation in the X chromosome.
Red Blood Cells
Warm Autoimmune Hemolytic Anemia (warm AIHA)
Warm AIHA: Immune system attacks red blood cells, causing anemia. Symptoms include fatigue, pallor, and jaundice. Treatment targets immune suppression.
Cold Agglutinin Disease
Cold Agglutinin Disease (CAD) is a rare autoimmune anemia. Cold-reactive antibodies destroy red blood cells, causing fatigue, cold sensitivity, and anemia.
Evans Syndrome
Evans syndrome: Rare autoimmune disorder causing low red blood cells & platelets (AIHA & ITP). Can lead to fatigue, bruising, and bleeding.
Wilson’s Disease
Wilson’s disease: A rare genetic disorder causing toxic copper buildup in the liver and brain. Early diagnosis and lifelong treatment are crucial.
Tachycardia in Hematological Patients
Tachycardia in hematology is critical. Often signals anemia, infection, or treatment issues. Early recognition improves patient outcomes.
Systemic Approach to Anemia
Systematic anemia diagnosis starts with a detailed history, exam & blood tests. Iron studies, B12/folate levels & other tests pinpoint the cause (iron deficiency, vitamin deficiency, etc.) leading to targeted treatment & improved outcomes.
Hereditary Hemochromatosis
Hereditary hemochromatosis, an inherited disorder, disrupts iron absorption leading to excessive iron buildup in organs like the liver, heart, and pancreas. Early diagnosis through blood tests is crucial to prevent potential complications like cirrhosis, heart failure, and diabetes. Treatment focuses on iron reduction through phlebotomy and may prevent severe health consequences.
Sideroblastic Anemia
Sideroblastic anemia disrupts iron use in red blood cells. Caused by genetic mutations or factors like alcohol abuse, it’s diagnosed by analyzing bone marrow for ring sideroblasts, iron-laden structures.
Differential Diagnosis of Macrocytic Anemias
Macrocytosis, larger-than-normal red blood cells, can be a sign of vitamin B12 or folate deficiency, liver disease, or bone marrow issues. Early diagnosis is key for targeted treatment.
Causes of Hypochromic Microcytic Anemia
Hypochromic microcytic anemia, marked by pale, small red blood cells, has various causes beyond iron deficiency. A proper diagnosis is crucial for effective treatment. Ruling out conditions like thalassemia or lead poisoning ensures targeted therapy.
Anemia of Chronic Disease (Anemia of Inflammation)
Anemia of Chronic Disease (Anemia of Inflammation) occurs when inflammation disrupts iron use for red blood cells, causing anemia despite iron stores.
