Clinical Classification Guidelines
Inclusion Terms
- Nephrotic syndrome with C3 glomerulopathy
Excludes Type 1
- Nephrotic syndrome (with C3 glomerulopathy) with dense deposit disease (N04.6)
Medical Intelligence & Overview
Nephrotic syndrome with C3 glomerulonephritis is a rare kidney disorder characterized by significant protein loss in the urine, swelling, and specific abnormalities in the kidney's filtering units. This condition involves inflammation of the glomeruli—tiny structures in the kidneys responsible for filtering blood—primarily due to immune system dysfunction affecting the C3 complement pathway. Recognizing and understanding this condition is crucial for early management and treatment planning.
Causes & Symptoms
Clinical Causes: Dysregulation of the complement system, especially the alternative pathway involving C3 Genetic mutations affecting immune regulation Underlying immune or autoimmune conditions that trigger abnormal immune responses Infections that precipitate immune activation and complement deposition Unknown factors, with some cases having no identifiable cause
Key Symptoms: Swelling (edema), particularly around the eyes, ankles, and abdomen Foamy urine due to high levels of protein Unintended weight gain from fluid retention Fatigue and weakness High blood pressure Decreased urine output in some cases Possible signs of kidney dysfunction, such as nausea or loss of appetite
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical assessment, laboratory tests, and kidney tissue analysis:
Treatment Protocols: Management strategies aim to control symptoms, reduce protein loss, and address underlying immune dysregulation:
