Systemic Lupus Erythematosus (SLE), commonly known as lupus, is a long-term autoimmune condition in which the body’s immune system mistakenly attacks its own tissues. While lupus can affect the skin, joints, heart, lungs, and brain, one of its most serious and potentially life-altering complications involves the kidneys. This condition is known as lupus nephritis.
At Bhagwan Mahavir Manipal Hospitals, Ranchi, our expert nephrologists and rheumatologists work closely together to diagnose lupus nephritis early and provide advanced, personalised treatment aimed at preserving kidney function and improving quality of life. This comprehensive guide will help you understand lupus nephritis treatment, symptoms, diagnosis, and long-term management.
Synopsis
What Is Lupus Nephritis?
Lupus nephritis is an inflammatory kidney condition caused by lupus. In people with SLE, the immune system produces abnormal antibodies that form immune complexes. These complexes get deposited in the kidneys, specifically in the tiny filtering units called glomeruli, leading to inflammation, swelling, and gradual damage.
Lupus nephritis is fairly common:
-
Around 50% of adults with lupus develop kidney involvement
-
Up to 80% of children with lupus may be affected
Without timely treatment, lupus nephritis can progress to chronic kidney disease or even kidney failure. Early diagnosis and expert care play a crucial role in protecting long-term kidney health.
Early Warning Signs and Symptoms of Lupus Nephritis
One of the biggest challenges with lupus nephritis is that it may not cause obvious symptoms in its early stages. This is why regular screening is essential for anyone diagnosed with lupus.
As kidney involvement progresses, symptoms may include:
-
Swelling (oedema): Puffiness around the eyes, ankles, feet, or legs, especially in the morning
-
Foamy or frothy urine: A sign of excess protein loss in urine (proteinuria)
-
High blood pressure: Often newly diagnosed or difficult to control
-
Blood in urine: Urine may appear pink, reddish, or cola-coloured
-
Unexplained weight gain: Caused by fluid retention
-
Frequent urination: Especially at night
-
Fatigue and weakness: Due to declining kidney function
If you notice any of these symptoms, seek medical advice promptly.
How Lupus Nephritis Is Diagnosed
At Bhagwan Mahavir Manipal Hospitals, Ranchi, diagnosis involves a step-by-step approach to assess kidney involvement and determine disease severity.
Blood and Urine Tests
-
Blood tests measure creatinine levels and calculate the estimated glomerular filtration rate (eGFR), which indicates how well the kidneys are functioning.
-
Urine tests check for protein, blood, and abnormal sediments that suggest kidney inflammation.
Kidney Biopsy
A kidney biopsy is the gold standard for diagnosing lupus nephritis. In this minimally invasive procedure, a small kidney tissue sample is examined under a microscope. The biopsy helps:
-
Confirm the diagnosis
-
Classify lupus nephritis (Class I to VI)
-
Guide treatment decisions and predict outcomes
This classification is essential for choosing the most effective therapy.
Lupus Nephritis Treatment at Bhagwan Mahavir Manipal Hospitals, Ranchi
The primary goals of lupus nephritis treatment are to:
-
Reduce kidney inflammation
-
Suppress abnormal immune activity
-
Prevent permanent kidney scarring
-
Preserve long-term kidney function
With modern therapies, over 80% of patients achieve partial or complete remission.
Induction Therapy: Controlling Active Disease
Induction therapy is the initial, intensive phase of treatment aimed at quickly controlling kidney inflammation. It usually involves immunosuppressive medications that calm the overactive immune system. The exact treatment plan depends on biopsy findings, disease severity, and the patient’s overall health.
Maintenance Therapy: Preventing Relapse
Once remission is achieved, patients transition to maintenance therapy. This phase uses lower medication doses to:
-
Maintain disease control
-
Prevent flare-ups
-
Minimise long-term side effects
-
Regular follow-ups are essential during this stage.
Managing Associated Conditions
Effective lupus nephritis treatment also includes managing related health issues such as:
-
High blood pressure, using kidney-protective medications
-
High cholesterol, through lifestyle changes and medication
-
Fluid retention, with dietary modifications
Lifestyle Measures That Support Lupus Nephritis Treatment
Medical therapy is vital, but daily lifestyle choices significantly influence long-term outcomes.

FAQ's
There is no permanent cure for lupus nephritis, but it can be effectively managed. Many patients achieve long-term remission with appropriate treatment.
With modern treatments and regular monitoring, most patients have a normal or near-normal life expectancy.
No. Most patients respond well to treatment and never require dialysis. Dialysis is needed only in advanced or untreated cases.
Pregnancy is possible but requires careful planning and close medical supervision. Disease remission before conception improves outcomes.
A low-sodium, balanced diet is recommended. Depending on kidney function, protein or potassium intake may need adjustment under a dietitian’s guidance.
