Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a genetic disorder that results in a deficiency of the enzyme G6PD, which plays a crucial role in the hexose monophosphate pathway. This pathway is important for protecting red blood cells from oxidative damage.
Causes
G6PD deficiency is an X-linked recessive condition, meaning it primarily affects males, while females can be carriers. The deficiency can lead to episodic hemolytic anemia under specific conditions, particularly when red blood cells are exposed to oxidative stress.
Triggers
Common triggers for hemolytic episodes include:
- Certain medications (e.g., sulfa drugs, aspirin, some antibiotics)
- Infections (particularly viral infections)
- Consumption of fava beans (a condition known as favism)
- Other oxidative stressors, such as certain food dyes
Symptoms
Symptoms of hemolytic anemia may include:
- Fatigue
- Jaundice (yellowing of the skin and eyes)
- Dark urine
- Shortness of breath
- Rapid heart rate
Diagnosis
G6PD deficiency can be diagnosed through a blood test that measures the level of G6PD enzyme activity.
Management
Management involves avoiding known triggers and treating any episodes of hemolysis that may occur. In severe cases, blood transfusions may be necessary. Individuals with G6PD deficiency should also have educational support to help them understand their condition and manage it effectively.
Prognosis
Most individuals with G6PD deficiency lead normal, healthy lives if they avoid triggers that can cause hemolytic episodes. Regular medical care and monitoring are recommended, especially during periods of illness or when considering new medications.
