Study Notes
G6PD Deficiency and Hemolytic Anemia
- A 29-year-old African American man taking primaquine developed jaundice, dark urine, anemia, reticulocytosis, and unconjugated hyperbilirubinemia four days after starting the medication. A peripheral smear revealed Heinz bodies.
- The most likely mode of inheritance for this condition is X-linked recessive.
- The most common trigger for hemolysis in patients with G6PD deficiency is drugs. Other triggers include infection, fava beans, and dehydration.
- Heinz bodies are seen in G6PD deficiency. They are formed from denatured globin chains. Macrophages in the spleen remove them.
- Features of a patient with G6PD deficiency and a suspected acute hemolytic episode may include anemia, splenomegaly, hemoglobinemia, cholelithiasis, and hemoglobinuria.
- A 23-year-old food blogger who ate fava beans experienced icterus and abdominal fullness. The condition might offer some protection against certain types of malaria.
Determining the Cause of Hemolytic Anemia
- A patient's peripheral smear showing a particular finding may indicate the cause of viral hepatitis.
- The most common class of antibodies involved in immunohemolytic anemia is IgG.
- Warm antibody immunohemolytic anemia is characterized by extravascular hemolysis.
- Cold agglutinin immunohemolytic anemia is characterized by extravascular and intravascular hemolysis.
Types of Hemolytic Anemia
- Hemolytic uremic syndrome, disseminated intravascular coagulation, and thrombotic thrombocytopenic purpura are conditions that might present with microangiopathic hemolytic anemia.
- Microangiopathic hemolytic anemia is most commonly seen in cases of disseminated intravascular coagulation.
- Paroxysmal cold hemoglobinuria is an autoimmune hemolytic anemia in which IgG antibodies target Rh antigens and complement-mediated lysis occurs at 37°C.
