Study Notes
Malignant Hypertension and Related Conditions
- Malignant hypertension characterized by severely elevated blood pressure leading to end-organ damage.
- Systemic lupus erythematosus (SLE) is an autoimmune condition with potential renal involvement and hypertension.
- Thrombotic thrombocytopenic purpura (TTP) involves microangiopathic hemolytic anemia, thrombocytopenia, and neurological symptoms.
- Hemolytic uremic syndrome (HUS) typically presents with hemolytic anemia, acute renal failure, and thrombocytopenia often following gastrointestinal infections.
- Disseminated cancer can provoke paraneoplastic syndromes impacting blood pressure regulation.
Hyperplasia of Mononuclear Phagocytes
- Activation of host defense mechanisms can lead to significant hyperplasia of mononuclear phagocytes.
- Results in pronounced splenomegaly and occasionally hepatomegaly due to increased immune system activity.
Malaria
- Malaria is a parasitic disease affecting red blood cells, often leading to hemolysis and splenomegaly.
- Can cause anemia and complications related to severe infection and sepsis.
Hemoglobinopathies
- Hemoglobinopathies are hereditary disorders caused by mutations leading to structural abnormalities in hemoglobin.
- Conditions include sickle cell disease and thalassemias, both with significant effects on red blood cell life span and function.
Clinical Features and Diagnosis
- Symptoms of hemolysis can include jaundice, fatigue, and splenomegaly.
- Prominent splenomegaly, hepatomegaly, and lymphadenopathy indicate extramedullary hematopoiesis and phagocyte hyperplasia.
- β-thalassemia major can be diagnosed strongly on clinical grounds, often manifesting in early childhood with severe anemia.
