N02.B
Recurrent and persistent immunoglobulin A nephropathy
Clinical Classification Guidelines
Medical Intelligence & Overview
Immunoglobulin A (IgA) nephropathy, also known as Berger's disease, is a kidney disorder characterized by the buildup of the antibody IgA in the kidneys. When this condition occurs repeatedly or persists over time, it is classified under the ICD-10 code N02B. This condition can lead to inflammation and damage to the kidney tissues, potentially resulting in impaired kidney function or kidney failure if not managed properly. Recognition of recurrent and persistent IgA nephropathy is essential for timely treatment and monitoring to prevent long-term complications.
Causes & Symptoms
Clinical Causes: Genetic predisposition influencing immune system responses Aberrant immune reactions to infections or environmental triggers Repeated infections, particularly respiratory or gastrointestinal illnesses Environmental factors such as exposure to certain toxins or pollutants Underlying autoimmune conditions that affect immune regulation
Key Symptoms: Blood in the urine (hematuria), which may be visible or microscopic Foamy or foamy urine due to high protein content Swelling in the hands, feet, face, or abdomen (edema) Fatigue or weakness High blood pressure (hypertension) Occasional episodes of kidney pain or discomfort
Diagnostic & Treatment
Diagnosis Path: Urinalysis to detect blood, protein, and signs of inflammation Blood tests measuring kidney function (creatinine, BUN) Renal biopsy to confirm the presence of IgA deposits in kidney tissues Imaging studies such as ultrasound to evaluate kidney size and structure Monitoring of blood pressure and urine protein levels over time
Treatment Protocols: Blood pressure management using antihypertensive medications, especially ACE inhibitors or ARBs Reducing protein intake to lessen kidney workload Medications to suppress immune response in active disease cases Management of edema with diuretics Controlling associated symptoms and infections promptly Regular monitoring of kidney function and disease progression In severe cases, dialysis or kidney transplantation may be necessary
