N02.B4
Recurrent and persistent immunoglobulin A nephropathy with diffuse membranous glomerulonephritis
Clinical Classification Guidelines
Medical Intelligence & Overview
Recurrent and persistent immunoglobulin A (IgA) nephropathy with diffuse membranous glomerulonephritis is a complex kidney disorder characterized by the buildup of IgA antibodies in the kidneys, leading to inflammation and damage. This condition involves ongoing inflammation and thickening of the tiny filtering units within the kidneys, known as glomeruli, which can impact kidney function over time. It often presents with persistent symptoms and requires careful medical monitoring to manage the disease effectively.
Causes & Symptoms
Clinical Causes: Genetic factors that predispose individuals to immune system abnormalities Infections, particularly those affecting the respiratory or gastrointestinal tracts Autoimmune responses where the body mistakenly attacks its own kidney tissues Environmental exposures that may trigger immune reactions Underlying chronic conditions that influence immune system activity
Key Symptoms: Blood in the urine (hematuria), which may appear pink or cola-colored Foamy or frothy urine due to excess protein excretion Swelling in the ankles, feet, or face (edema) High blood pressure (hypertension) Fatigue and decreased energy levels Back pain or discomfort in the kidney area Occasional decrease in urine output
Diagnostic & Treatment
Diagnosis Path: Diagnosis of this condition involves a combination of medical history, physical examination, and laboratory tests. A kidney biopsy is often performed to confirm the diagnosis, revealing characteristic changes in the glomeruli such as IgA deposits and membranous thickening. Blood tests may show impaired kidney function and elevated blood pressure, while urine tests typically reveal blood and protein. Imaging studies are generally not primary diagnostic tools but can assist in assessing kidney size and structure.
Treatment Protocols: Treatment strategies aim to slow disease progression and manage symptoms. They may include:
