Membranous Nephropathy
A Cause of Heavy Protein Loss That Can Progress to Kidney Failure
A kidney disorder where the immune system damages the filtering membranes (glomeruli), leading to significant protein loss in urine and gradual decline in kidney function.

How Membranous Nephropathy Affects Kidneys

Progressive declineImportant: Variable Course
Some patients remain stable for years
Some may go into remission
Others may progress to kidney failure
Regular monitoring is essential.
What is Membranous Nephropathy?
Membranous Nephropathy is an autoimmune kidney disease where immune complexes deposit along the kidney's filtering membranes.
This thickens and damages the glomeruli, causing protein to leak into the urine.
Over time, persistent protein loss can lead to Chronic Kidney Disease (CKD) and, in some cases, kidney failure.
Early Signs & Symptoms
Swelling in legs, feet, or around eyes
Foamy urine (protein leakage)
Weight gain due to fluid retention
Fatigue
High blood pressure (in some cases)
Causes & Risk Factors
Primary (Idiopathic)
- Autoimmune origin
- No clear external cause
Secondary Causes
- Infections
- Certain medications
- Autoimmune diseases
- Rarely, associated with malignancies
Disease Progression
Early Stage
Protein leakage begins
Kidney function preserved
Best time for intervention
Moderate Stage
Increasing proteinuria
Gradual decline in function
Advanced Stage
Significant kidney damage
Symptoms worsen
End Stage (Kidney Failure)
Dialysis or transplant required
Diagnosis & Tests
Urine test
Protein levels (proteinuria)Blood tests
Creatinine, Albumin levelsKidney biopsy
Confirmatory testAntibody testing
PLA2R antibody in some casesCheck Your Condition Status
Understand your disease stage and next steps
Treatment Options (Before Transplant)
1. Supportive Treatment
- Blood pressure control
- Proteinuria management
2. Immunosuppressive Therapy
- Steroids or other agents
- Used in moderate to severe cases
3. Lifestyle Management
- Salt restriction
- Fluid management
4. Dialysis (Advanced Stage)
- Required if kidney failure develops
When is Kidney Transplant Needed?
Kidney function declines to advanced stages
Patient becomes dialysis-dependent
Disease progresses despite treatment

Important Consideration: Recurrence Risk
There is a possibility of recurrence after transplant, but outcomes are generally good with proper monitoring.
Dialysis vs Transplant
Dialysis
Ongoing • Limited quality • Moderate outcome
Transplant
One-time surgery • Improved quality • Better outcomes
