Clinical Classification Guidelines
Inclusion Terms
- Chronic nephritic syndrome with C3 glomerulopathy
Excludes Type 1
- Chronic nephritic syndrome (with C3 glomerulopathy) with dense deposit disease (N03.6)
Medical Intelligence & Overview
Chronic nephritic syndrome with C3 glomerulonephritis is a kidney disorder characterized by long-lasting inflammation of the small blood vessels in the kidneys, known as glomeruli. This condition can impair the kidneys' ability to filter waste and excess fluid from the blood, leading to various health issues. It is classified under ICD-10 code N03.A and involves a specific type of glomerulonephritis where the complement protein C3 plays a significant role in the disease process.
Causes & Symptoms
Clinical Causes: Abnormal immune system activity leading to deposition of C3 protein in the glomeruli Genetic predispositions affecting the regulation of the complement pathway Infections that trigger immune responses damaging kidney structures Other autoimmune diseases that can involve kidney inflammation Unknown factors, as the exact cause often remains idiopathic
Key Symptoms: Blood in the urine (hematuria) Protein in the urine (proteinuria) Swelling in the legs, ankles, or face (edema) High blood pressure (hypertension) Reduced kidney function, which may lead to fatigue or weakness Foamy urine due to excess protein Frequent urination, especially at night (nocturia)
Diagnostic & Treatment
Diagnosis Path: Diagnosing this condition involves a combination of medical history, physical examinations, laboratory tests, and kidney biopsies. Specific diagnostic procedures include:
Treatment Protocols: Management of chronic nephritic syndrome with C3 glomerulonephritis focuses on controlling inflammation, preserving kidney function, and preventing complications. Typical approaches include:
