I have lupus nephritis. How do I prevent further renal damage?

Question

Hello doctor,

I was diagnosed with lupus two years ago, and my recent blood tests show that my kidney function is declining, with protein in my urine. I have been experiencing swelling in my feet, ankles, and around my eyes, especially in the morning when I wake up.

My blood pressure has been elevated during my last few doctor visits, and I feel more tired than usual, even with my lupus medication. I am concerned because my rheumatologist mentioned that lupus can affect the kidneys, and I want to understand what this means for my long-term health.

How does lupus affect kidney function, and what treatments are available to protect my kidneys and prevent further damage?

Please help.

Hello,

Welcome to icliniq.com.

I understand your concern.

Based on your description, you have suspected lupus nephritis with declining kidney function. Lupus is an autoimmune disease in which the immune system attacks healthy tissues. When it affects the kidneys, it causes inflammation in the filtering units called glomeruli.

This inflammation allows protein and sometimes blood to leak into the urine. Protein in the urine, swelling around the eyes and ankles, high blood pressure, and fatigue are classic signs of kidney involvement. If untreated, ongoing inflammation can gradually reduce kidney function over time.

A kidney biopsy is often required to confirm the diagnosis and determine the severity and type of lupus nephritis. The biopsy guides treatment decisions.

The treatment plan for lupus nephritis includes:

High-dose corticosteroids to rapidly reduce inflammation.
Immunosuppressive medications such as Mycophenolate mofetil or Cyclophosphamide for more severe disease.
Maintenance therapy with Mycophenolate or Azathioprine after initial control.
Hydroxychloroquine should usually be continued.
ACE (angiotensin converting enzyme) inhibitors and ARBs (angiotensin receptor blockers) to lower blood pressure and reduce protein loss in the urine.
Salt restriction and careful fluid management.

To prevent further disease progression, you should follow the suggestions below:

Strict blood pressure control.
Regular monitoring of kidney function and urine protein.
Avoid NSAIDs (non-steroidal anti-inflammatory drugs) unless approved.
Control cholesterol and cardiovascular risk.
Medication adherence is critical.

With early and aggressive treatment, many patients stabilize their kidney function and avoid dialysis. Kidney failure is not inevitable, but prompt specialist care and close monitoring are essential to protect long-term kidney health.

I hope this helps.

Thank you.
