D72.81
Decreased white blood cell count
Clinical Classification Guidelines
Excludes Type 1
- neutropenia (D70.-)
Medical Intelligence & Overview
A decreased white blood cell count, also known as leukopenia, is a condition where the number of white blood cells (WBCs) in the blood is lower than normal. White blood cells play a vital role in defending the body against infections and disease. When their levels drop, the immune system becomes weaker, making individuals more susceptible to infections. This medical condition is classified under ICD-10 code D72.81 and requires attention to diagnose the underlying causes and determine appropriate care.
Causes & Symptoms
Clinical Causes: Viral infections that temporarily suppress bone marrow function Bone marrow disorders such as aplastic anemia or leukemia Autoimmune conditions, where the body's immune system attacks white blood cells Certain medications, including chemotherapy, antibiotics, and immunosuppressants Nutritional deficiencies, especially of vitamin B12, folate, or copper Radiation therapy or exposure to toxic chemicals Chronic medical conditions like HIV/AIDS or cirrhosis Genetic disorders affecting blood cell production
Key Symptoms: Increased frequency of infections Fever and chills Sore throat and mouth sores Persistent weakness or fatigue Unusual bleeding or bruising Recurrent or unusual infections Swollen lymph nodes or enlarged spleen Painless skin ulcers in some cases
Diagnostic & Treatment
Diagnosis Path: Diagnosing a decreased white blood cell count involves a comprehensive medical evaluation, including blood tests like a complete blood count (CBC) to determine WBC levels. Additional tests may be needed to identify underlying causes, such as bone marrow biopsies, blood cultures, or tests for infectious diseases. Healthcare providers will also review the patient's medical history and conduct physical examinations to look for signs related to underlying conditions or causes.
Treatment Protocols: Adjusting or discontinuing medications that cause leukopenia Treating infections promptly to prevent complications Nutritional supplementation for deficiencies Growth factor therapies like granulocyte colony-stimulating factor (G-CSF) in severe cases Treating underlying medical conditions such as autoimmune diseases or bone marrow disorders Implementing protective measures against infections, such as good hygiene and avoiding contact with sick individuals
