Diagnosis and Management of G6PD Deficiency

Doctors suspect G6PD deficiency in people who develop jaundice during an infectious illness or after taking a drug that is known to trigger an episode. Blood tests, including examining a blood smear, are done to see if red blood cells are breaking down. If they are, doctors can measure G6PD activity in red blood cells.

In newborns, the treatment focuses on managing jaundice and preventing kernicterus. In older patients, management depends primarily on the overall clinical picture. Less severe presentations may be managed with supportive care and discontinuation and avoidance of the offending agents. If you have mild deficiency symptoms, then transfusion is usually not recommended. In case of a severe hemolytic crisis, your doctor will give you a blood transfusion of either whole blood or packed cells. In areas where glucose-6-phosphate dehydrogenase (G6PD or G-6-PD) deficiency (G6PDD) is very common, the doctor will avoid giving G6PD-deficient blood to patients.

  1. This may require hospitalization and immediate blood transfusion.
  2. In more serious cases, your baby’s healthcare provider may recommend what’s called an exchange transfusion.
  3. They measure G6PD activity during blood cell breakdown and then again after it has stopped.
  4. A deficiency in this enzyme causes the red blood cell to be destroyed (hemolysis), leading to anemia and jaundice (yellowing of the skin).
  5. However, it’s important to learn how you can manage the condition and prevent symptoms from developing.

Anemia with elevated reticulocyte count is consistent with hemolytic anemia. Other labs might include a bilirubin count, which will be elevated. Bilirubin is released from red blood cells when they are broken down and causes jaundice during hemolytic crises. Once G6PD deficiency has progressed to hemolytic anemia, however, more aggressive treatment may be required.

Hence, men are more likely to suffer from this disorder than women. Glucose-6-phosphate dehydrogenase (G6PD) deficiency (G6PDD) is a genetic (hereditary) disorder. However, you can prevent the more serious G6PDD symptoms by avoiding certain foods. You should see your healthcare provider any time you develop G6PD deficiency symptoms. Seek immediate medical help if your symptoms are severe and come on quickly.

Also, G6PD deficiency can sometimes happen in people who do not have the gene for the condition. This type is caused by other conditions, such as diabetes and hyperaldosteronism (2, 13). A child with one X and one Y chromosome (usually assigned male at birth) will develop i need help dealing with my angry and alcoholic mother G6PD deficiency if they receive this gene. If a child receives an X chromosome containing the gene that causes G6PD deficiency, they will either be a carrier of the condition or develop it. G6PD deficiency occurs when your body does not have enough of the enzyme G6PD.

Therefore, it is important that patients who are known or suspected to have any degree of G6PD deficiency not receive methylene blue. Alternative therapies for G6PD deficient patients presenting with methemoglobinemia opinion fighting hopelessness in treating addiction the new york times include transfusing packed red blood cells or providing hyperbaric oxygen therapy. Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a genetic condition that can be passed down from parents to their children.

It’s a type of hemolytic anemia, meaning oxygen-carrying red blood cells break down too fast (called hemolysis), leading to a lack of red blood cells. G6PD is also responsible for keeping red blood cells healthy so they can function properly and live a normal life span. This early destruction of red blood cells is known as hemolysis, and it can eventually lead to hemolytic anemia.

Ask your doctor for a printed list of medications and foods that you should avoid. The mechanism by which G6PD deficiency causes neonatal hyperbilirubinemia is not completely understood. The symptoms of hemolytic anemia may look like other health problems. Exercise can induce oxidative stress, which is a trigger for hemolytic anemia in people with G6PD deficiency (5, 21).

Advisory for Baltimore-Area Patients

They measure G6PD activity during blood cell breakdown and then again after it has stopped. G6PD is an enzyme important for maintaining the stability of hemoglobin. Hemoglobin is the protein contained in red blood cells that enables them to carry oxygen from the lungs and deliver it to all parts of the body. G6PD helps protect hemoglobin from damage due to the stress of infections or the use of certain drugs or substances. People who have G6PD deficiency inherit a defect in the gene responsible for producing G6PD so they do not have enough of the enzyme in their blood cells.

Foods to avoid

The defective gene that causes this deficiency is on the X chromosome, which is one of the two sex chromosomes. Men have only one X chromosome, while women have two X chromosomes. In males, one altered copy of the gene is enough to cause G6PD deficiency. Although rare, G6PD deficiency should be considered as a cause of any chronic nonspherocytic hemolytic anemia across all population groups.

Risk Factors

Read more , meaning that mainly males are affected and females are carriers of the defective gene. However, activity of the G6PD gene is highly variable, so in some people G6PD does not work quite as well as it should and in others it does not work at all. Triggers to be avoided include certain foods, such as fava beans; some medications; and some substances, including henna. Because of these factors, people assigned male at birth are more likely to receive a diagnosis of symptomatic G6PD deficiency. On average, people assigned female at birth are more likely to have the G6PD deficiency gene but less likely to develop serious symptoms (1, 12). Therefore, this disorder is transmitted through the faulty genes of mothers (who are usually healthy carriers) to their son (or daughter who again becomes another healthy carrier ).

The type of mutation inherited will determine the activity level of the G6PD enzyme and the resulting severity of symptoms. If the condition was triggered by an infection, then the underlying infection is treated accordingly. Any current medications that may be destroying red blood cells are also discontinued.

Having one or more of these risk factors doesn’t necessarily mean that you will have G6PD deficiency. Talk with your doctor if you’re concerned about your risk for the condition. Women who carry one copy of the gene can pass G6PD deficiency to their children.

In the United States, black males are most commonly affected, with a prevalence of approximately 10 percent. Fava beans can lead to hemolytic anemia in some individuals with G6PD deficiency. In one study, 33% of participants with G6PD deficiency experienced hemolytic anemia due to eating fava beans.
