What is Chronic Granulomatous Disease?
In this section, we will delve into the details of Chronic Granulomatous Disease (CGD), understanding its impact on neutrophil function and its classification as an immunodeficiency syndrome.
CGD, also known as Neutrophil Dysfunction, is a rare genetic disorder that affects the immune system. It is classified as an immunodeficiency syndrome because it impairs the body’s ability to fight off certain types of bacterial and fungal infections.
CGD is characterized by a malfunction in the neutrophils, which are a type of white blood cell responsible for defending the body against infections. Neutrophils play a crucial role in the immune system by engulfing and destroying harmful bacteria and fungi. However, in individuals with CGD, the neutrophils are unable to produce the necessary reactive oxygen species required to kill these pathogens effectively.
This defect in neutrophil function leaves individuals with CGD susceptible to recurrent and severe infections, particularly in the lungs, skin, and other organs. The inability to eliminate these infections can lead to the formation of granulomas, which are clumps of immune cells and tissue that can cause significant damage.
To better understand the impact of CGD on neutrophil function, let’s take a closer look at the key components involved:
The Role of Neutrophils in CGD:
Neutrophils are a type of white blood cell that forms a crucial part of the body’s first line of defense against infections. They are quick to respond to invading pathogens and help contain and eliminate them from the body.
In individuals without CGD, neutrophils engulf bacteria and fungi in a process called phagocytosis and then produce reactive oxygen species, such as hydrogen peroxide, to kill the pathogens. However, in individuals with CGD, this process is disrupted due to genetic mutations that affect the enzymes responsible for the production of these reactive oxygen species.
Without the effective production of reactive oxygen species, neutrophils in individuals with CGD are unable to effectively kill bacteria and fungi, resulting in persistent and recurrent infections. The impaired neutrophil function also leads to the formation of granulomas, which are clusters of immune cells that accumulate in response to the persistent presence of pathogens.
The understanding of CGD as an immunodeficiency syndrome provides critical insights into the underlying mechanisms of the disease and directs researchers towards developing targeted therapies to address the neutrophil dysfunction and associated symptoms.
Classification of CGD as an Immunodeficiency Syndrome:
Immunodeficiency syndromes are a group of disorders characterized by defects in the immune system, making individuals more susceptible to infections.
In the case of CGD, the dysfunction of neutrophils, the key cells responsible for fighting off infections, classifies it as an immunodeficiency syndrome. The impaired ability of neutrophils to produce reactive oxygen species weakens the body’s defense mechanisms against certain bacteria and fungi.
It’s important to note that CGD is just one of several immunodeficiency syndromes, each with unique characteristics and underlying genetic mutations. Understanding the classification of CGD as an immunodeficiency syndrome helps medical professionals and researchers categorize and study the condition for accurate diagnosis and management.

Diagnosis of Chronic Granulomatous Disease
Diagnosing Chronic Granulomatous Disease (CGD) involves a comprehensive evaluation of the patient’s medical history, symptoms, and laboratory tests. Two important diagnostic methods used to identify CGD are the Nitroblue Tetrazolium (NBT) test and the identification of genetic mutations.
Nitroblue Tetrazolium (NBT) Test
The Nitroblue Tetrazolium (NBT) test is a diagnostic tool used to assess the neutrophil function, which is impaired in individuals with CGD. This test measures the ability of neutrophils to convert NBT into a blue-colored compound called formazan. A reduced ability of neutrophils to produce formazan indicates a possible diagnosis of CGD.
During the NBT test, blood samples are collected and incubated with a chemical called NBT. The neutrophils in the blood are then activated using a stimulant, such as phorbol myristate acetate. If the neutrophils are functioning normally, they will produce formazan and turn blue. However, in individuals with CGD, the neutrophils will not be able to generate formazan, resulting in a less intense or absent blue color.
It’s important to note that the NBT test alone cannot confirm a diagnosis of CGD, as certain conditions and medications can also affect the test results. Therefore, additional tests are required to confirm the diagnosis.
Genetic Mutations
Genetic testing plays a crucial role in diagnosing CGD. It involves analyzing the patient’s DNA for specific mutations in genes associated with CGD, such as CYBB, NCF1, NCF2, and NCF4. These genes provide instructions for the production of proteins involved in the function of the NADPH oxidase enzyme complex, which is responsible for producing reactive oxygen species in neutrophils.
Identifying genetic mutations associated with CGD can help confirm the diagnosis and determine the specific subtype of CGD. Different subtypes of CGD are associated with specific genetic mutations and variations in the severity of symptoms and complications.
Genetic testing can be performed using various techniques, including sequencing the entire coding regions of the relevant genes or using targeted gene panels. Additionally, if a known mutation is present in a family member, targeted testing can be done to determine if other family members are also affected.
The combination of the NBT test and genetic testing allows for a more accurate diagnosis of CGD, guiding further treatment and management strategies.
