What is associated with Favism?

Consumption of faba beans (Vicia faba) or inhalation of its pollen has been associated with the disease known as favism or pollinosis. The symptom is characterized by hemolytic anemia, hemoglobinuria, and shock. The toxic compounds are vicine (glucose + divicine) and convicine (glucose + isouramil).

What causes Favism?

Triggers of hemolysis in G6PD-deficient persons include certain infectious diseases, certain drugs, and eating fava beans: this can cause a potentially serious acute hemolytic anemia known as favism.

Where is g6pdh found?

Glucose-6-phosphate dehydrogenase is an enzyme found in the cytoplasm of all cells in the body. It is a housekeeping enzyme that plays a vital role in the prevention of cellular damage from reactive oxygen species. It does this by providing substrates to prevent oxidative damage.

What is the meaning of G6PD?

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a condition in which red blood cells break down when the body is exposed to certain drugs or the stress of infection. It is hereditary, which means it is passed down in families.

Who is susceptible to favism?

The known distribution of the disease is largely limited to people of Mediterranean origins (Spaniards, Italians, Greeks, Armenians, and Jews). Susceptibility to favism is inherited as a sex-linked trait and appears to be closely related to glucose-6-phosphate dehydrogenase deficiency (q.v.).

How is favism diagnosed?

Your doctor can diagnose G6PD deficiency by performing a simple blood test to check G6PD enzyme levels. Other diagnostic tests that may be done include a complete blood count, serum hemoglobin test, and a reticulocyte count.

What foods should G6PD avoid?

Your child should not eat fava beans. Some people should also avoid red wine, all beans, blueberries, soya products, tonic water and camphor.

What happens when G6PD is triggered?

This can cause tiredness, dizziness, and other symptoms. Red blood cells that don’t have enough G6PD are sensitive to some medicines, foods, and infections. When these things trigger a quick loss of red blood cells over a short time, it’s called a hemolytic crisis.

Does favism go away?

Favism does not typically recur after subsequent FB ingestion. The pathogenesis of favism cannot be explained by G6PD deficiency alone but suggests the involvement of an infectious agent such as a virus.

What is hemolytic anaemia?

Hemolytic anemia is a disorder in which red blood cells are destroyed faster than they can be made. The destruction of red blood cells is called hemolysis. Red blood cells carry oxygen to all parts of your body.
