N00.B2
Acute nephritic syndrome with secondary immune complex membranoproliferative glomerulonephritis (IC-MPGN)
Clinical Classification Guidelines
Medical Intelligence & Overview
Acute nephritic syndrome with secondary immune complex membranoproliferative glomerulonephritis (IC-MPGN) is a kidney condition characterized by inflammation and damage to the glomeruli, which are tiny filtering units within the kidneys. This condition often occurs as a complication of underlying immune-related diseases and can lead to impaired kidney function if not properly managed. Recognizing symptoms early and understanding the condition can help in seeking appropriate medical care.
Causes & Symptoms
Clinical Causes: Immune system disorders such as systemic lupus erythematosus (SLE) Infections like hepatitis B or C, and bacterial endocarditis Cryoglobulinemia, a condition where abnormal proteins in the blood precipitate at low temperatures Other autoimmune diseases that activate immune responses against kidney tissues Certain medications or toxins that may trigger immune reactions Genetic predispositions affecting immune regulation
Key Symptoms: Hematuria (blood in the urine) Proteinuria (excess protein in the urine) Swelling or edema, especially around the eyes, face, or ankles High blood pressure Reduced urine output Fatigue and weakness Signs of underlying infections or autoimmune diseases, such as rash or joint pain
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of laboratory tests, imaging, and sometimes a kidney biopsy. Tests may include blood work to assess kidney function and immune activity, urinalysis to identify blood and protein in the urine, and serologic testing for infections or autoimmune markers. A kidney biopsy can provide definitive information about the pattern of glomerular damage and immune complex deposits, confirming the diagnosis of IC-MPGN.
Treatment Protocols: Use of corticosteroids to reduce inflammation Immunosuppressive medications to modulate immune activity Blood pressure control with antihypertensive drugs, particularly ACE inhibitors or angiotensin receptor blockers Treating underlying infections or autoimmune diseases with appropriate therapy Lifestyle modifications such as salt restriction and maintaining a healthy diet Regular monitoring of kidney function and urine tests to assess disease progression

Documentation
How do I report N00.B2?
Clinical documentation must specify the nature of Acute nephritic syndrome with secondary immune complex membranoproliferative glomerulonephritis (IC-MPGN) and any associated comorbidities for accurate reporting.
