R80.3
Bence Jones proteinuria
Clinical Classification Guidelines
Medical Intelligence & Overview
Bence Jones proteinuria is a medical condition characterized by the presence of abnormal light chain proteins, known as Bence Jones proteins, in the urine. This condition is often associated with multiple myeloma and other plasma cell disorders. Detecting Bence Jones proteins is crucial for diagnosing and managing certain hematological diseases, particularly multiple myeloma. The condition itself does not typically cause symptoms but indicates an underlying health issue that requires medical evaluation.
Causes & Symptoms
Clinical Causes: Multiple myeloma: A cancer of plasma cells that produces excessive abnormal proteins. Waldenström's macroglobulinemia: A lymphoplasmacytic lymphoma that can produce light chains. Amyloidosis: A disorder where abnormal protein deposits can include light chains. Other plasma cell dyscrasias: Rare conditions leading to abnormal light chain production. Heavy chain diseases: Rare lymphoproliferative disorders involving abnormal immunoglobulin production.
Key Symptoms: Often asymptomatic and discovered during routine urine tests. Signs related to underlying disorders such as multiple myeloma may include bone pain, fatigue, weakness, weight loss, or recurrent infections. In cases where kidney damage occurs, symptoms may include swelling in the legs or ankles (edema), decreased urine output, or signs of kidney impairment. No specific symptoms directly caused by Bence Jones proteins, but their presence indicates underlying disease activity.
Diagnostic & Treatment
Diagnosis Path: Diagnosis of Bence Jones proteinuria involves several laboratory tests:
Treatment Protocols: Treatment of Bence Jones proteinuria focuses on managing the underlying condition:
