Agranulocytosis

Agranulocytosis is a rare but serious blood disorder characterized by a critically low number of granulocytes, particularly neutrophils, which are essential white blood cells responsible for fighting bacterial and fungal infections. When neutrophil levels fall drastically, the body's immune system becomes severely weakened, making even minor infections potentially life-threatening. Agranulocytosis may develop due to certain medications, chemotherapy, autoimmune diseases, bone marrow disorders, severe infections, or exposure to toxic chemicals. In some cases, the exact cause remains unknown.

Common symptoms include sudden high fever, chills, sore throat, mouth ulcers, fatigue, swollen lymph nodes, and recurrent or severe infections. Since symptoms can progress rapidly, immediate medical evaluation is essential. Diagnosis involves a complete blood count (CBC), differential white blood cell count, bone marrow examination when necessary, and investigations to identify the underlying cause.

Treatment focuses on removing the triggering factor, administering broad-spectrum antibiotics for infections, and providing supportive care. Granulocyte colony-stimulating factor (G-CSF) may be prescribed to stimulate neutrophil production and accelerate recovery. Patients are also advised to maintain strict hygiene and avoid exposure to infectious agents during recovery.

Early diagnosis and prompt treatment significantly improve outcomes. Regular monitoring is especially important for individuals taking medications known to increase the risk of agranulocytosis, ensuring timely intervention and preventing serious complications.
