Chronic Granulomatous Disease (CGD)

11 min read

Chronic Granulomatous Disease (CGD) is a rare, inherited disorder of the immune system. It is caused by a genetic defect that affects the ability of certain white blood cells to fight off certain types of bacteria and fungi. CGD is characterized by the formation of granulomas, which are collections of immune cells that form in response to an infection. People with CGD are at an increased risk of developing recurrent and severe infections.

Causes of CGD

CGD is caused by a genetic defect in the genes responsible for producing the enzyme NADPH oxidase. This enzyme is responsible for producing reactive oxygen species, which are important for killing bacteria and fungi. Without this enzyme, the body is unable to fight off certain types of infections.

Diagnosis of CGD

CGD is typically diagnosed through a combination of physical examination, laboratory tests, and genetic testing. Physical examination may reveal signs of recurrent infections, such as enlarged lymph nodes or skin lesions. Laboratory tests may include a complete blood count, a white blood cell count, and a test for the presence of the NADPH oxidase enzyme. Genetic testing can confirm the diagnosis of CGD.

Complications of CGD

People with CGD are at an increased risk of developing recurrent and severe infections. These infections can affect the lungs, skin, and other organs. In addition, people with CGD may be at an increased risk of developing certain types of cancer, such as lymphoma or leukemia.

Prognosis of CGD

The prognosis for people with CGD depends on the severity of the disease and the person's response to treatment. With proper treatment, most people with CGD can lead a normal life. However, some people may experience recurrent infections and other complications.

Causes

Genetic Causes

CGD is caused by a mutation in one of the genes responsible for producing NADPH oxidase. These mutations can be inherited from a parent or can occur spontaneously. The most common form of CGD is caused by a mutation in the CYBB gene, which is located on the X chromosome. Other genes that can cause CGD include NCF1, NCF2, and CYBA.

Environmental Causes

In some cases, environmental factors can also contribute to the development of CGD. Exposure to certain chemicals, such as benzene, can damage the NADPH oxidase enzyme and lead to CGD. Additionally, certain medications, such as anticonvulsants, can also increase the risk of developing CGD.

Conclusion

Chronic Granulomatous Disease (CGD) is a rare genetic disorder that affects the body’s ability to fight off certain types of infections. It is caused by a mutation in one of the genes responsible for producing an enzyme called NADPH oxidase. In some cases, environmental factors can also contribute to the development of CGD. If you or a loved one has been diagnosed with CGD, it is important to speak with a doctor to discuss treatment options.

Getting a Diagnosis

Clinical Symptoms

The most common symptoms of CGD include recurrent bacterial and fungal infections, such as abscesses, pneumonia, and skin infections. Other symptoms may include chronic diarrhea, weight loss, and fever. These symptoms may be present from birth or may develop over time.

Laboratory Tests

Laboratory tests are used to diagnose CGD. These tests measure the levels of certain enzymes in the blood and can help to identify the genetic mutation that is causing the disorder. These tests may include a complete blood count, a white blood cell count, and a test to measure the levels of certain enzymes in the blood.

Genetic Testing

Genetic testing is used to confirm the diagnosis of CGD. This test looks for the genetic mutation that is causing the disorder. It is important to note that genetic testing is not always necessary for diagnosis, as the clinical symptoms and laboratory tests can often be enough to make a diagnosis.

Treatment

Treatment for CGD is aimed at preventing and treating infections. This may include antibiotics, antifungal medications, and immunosuppressive drugs. In some cases, a bone marrow transplant may be recommended to replace the defective cells with healthy ones.
