UMEM Educational Pearls

-    The most common disease producing enzymopathy in humans

-    Affects 400 million people worldwide

-    Highest prevalence is among persons of African, Asian, and Mediterranean descent

-    Patients can be asymptomatic but may present with symptoms of acute hemolytic anemia, which may be precipitated by certain medications (Oxidative medications) or foods (some types of beans)

-    Avoid oxidative drugs (consult your PharmD when your patient has G6PDd)

-    Diagnosis: Measure the actual enzyme activity of G6PD rather than the amount of the enzyme. A more practical test is the presence of Indirect hyperbilirubinemia, but it is non specific

-    Treatment consists of oxygen and bed rest in minor cases. However, severe cases may require PRBC transfusion
