Table of Contents
Agranulocytosis is a hematologic disorder marked by a severe reduction in granulocytes, especially neutrophils, in the blood. These cells play a key role in fighting bacterial infections, and their deficiency significantly weakens the body's immune defense. Understanding its causes, symptoms, diagnosis, and treatment options is important for timely care and better outcomes.
What Are the Types of Agranulocytosis?
Agranulocytosis can be classified into the following types based on its origin:
- Congenital agranulocytosis: A rare inherited condition where a person is born with low granulocyte levels
- Acquired agranulocytosis: Develops due to external factors like medications, infections, or autoimmune disorders
What Are the Symptoms of Agranulocytosis?
The symptoms are mainly related to infections due to low white blood cell counts. These signs may appear suddenly and can worsen quickly if untreated.
- Fever: Persistent high temperature indicating infection
- Mouth ulcers: Painful sores in the mouth and throat
- Fatigue: Severe and unexplained tiredness
- Sore throat: Continuous discomfort or pain while swallowing
- Skin infections: Frequent or severe infections of the skin
In severe cases, it can lead to life-threatening infections such as sepsis and requires immediate medical care.
What Causes Agranulocytosis?
Medications
Drug reactions are one of the most common causes. Certain medications can suppress bone marrow function or destroy white blood cells.
- Antibiotics: Chloramphenicol, sulfonamides
- Antithyroid drugs: Methimazole, propylthiouracil
- Antipsychotics: Clozapine
- Chemotherapy agents: Alkylating agents, antimetabolites
Infections and autoimmune disorders
Some infections and immune-related conditions can affect bone marrow or destroy granulocytes.
Viral infections such as Epstein-Barr virus and HIV may reduce production, while autoimmune diseases like systemic lupus erythematosus can attack the body's own cells.
Other causes
- Radiation therapy: High radiation exposure can damage bone marrow
- Toxins: Chemicals like benzene can impair blood cell production
- Nutritional deficiencies: Low levels of vitamin B12 and folate can affect cell formation
When Should You See a Doctor for Agranulocytosis?
Early medical attention is essential, especially when symptoms suggest infection or immune suppression.
- Persistent fever or chills
- Frequent infections or slow healing
- Severe sore throat or mouth ulcers
- Unexplained fatigue or weakness
A hematologist or general physician typically manages this condition, depending on severity and underlying cause.

How is Agranulocytosis Diagnosed?
Blood tests
Diagnosis usually starts with a complete blood count (CBC) to check granulocyte levels. A significant drop confirms suspicion.
Bone marrow biopsy
A bone marrow sample may be examined to identify the cause and assess production of blood cells.
Additional tests
Further investigations depend on the suspected cause.
- Viral cultures: To detect infections
- Autoantibody tests: To identify autoimmune conditions
- Toxin screening: To check for chemical exposure
What Are the Treatment Options for Agranulocytosis?
Discontinuation of causative medications
If drug-induced, stopping the responsible medication is the first step, and recovery often follows.
Antibiotic therapy
Broad-spectrum antibiotics are given to manage or prevent serious infections, often through intravenous administration.
Granulocyte colony-stimulating factor (G-CSF)
This treatment stimulates the bone marrow to produce more granulocytes, especially useful in severe or chemotherapy-related cases.
Immunosuppressive therapy
Used in autoimmune-related cases to reduce immune system activity and prevent further cell destruction.
Bone marrow transplant
In severe or congenital cases, a transplant may be required to restore normal blood cell production.

What is the Recovery Process for Agranulocytosis?
Recovery depends on the underlying cause and how early treatment begins. With proper care, many patients recover well.
- Regular monitoring of blood counts
- Avoiding infections and maintaining hygiene
- Following medication and treatment plans strictly
- Nutritional support to improve bone marrow function
Recovery may take days to weeks, especially after stopping causative drugs or starting supportive treatment.
Prevention of Agranulocytosis
Medication management
Careful use and monitoring of high-risk medications help in early detection and prevention.
Avoiding toxins
Reducing exposure to harmful chemicals like benzene lowers the risk.
Nutritional support
A balanced diet with adequate vitamin B12 and folate supports healthy blood cell production.
Frequently Asked Questions
1. What are the symptoms of agranulocytosis?
Symptoms of agranulocytosis include fever, chills, sore throat, mouth ulcers, and increased susceptibility to infections.
2. How can agranulocytosis be prevented?
Preventing agranulocytosis involves avoiding medications that cause it, such as certain antibiotics or chemotherapy drugs.
3. What causes agranulocytosis?
Agranulocytosis is caused by a significant reduction in neutrophils, often due to medications, infections, or autoimmune disorders.
4. What are the types of agranulocytosis?
Types include congenital agranulocytosis and acquired agranulocytosis, which is typically drug-induced.
5. What are the treatment options for agranulocytosis?
Treatment involves stopping the causative drug, antibiotics for infections, and growth factor injections like G-CSF to stimulate neutrophil production.
