Nephrology focuses on diagnosing and treating kidney diseases. The kidneys filter waste, balance fluids, regulate blood pressure, and manage acute and chronic conditions.

Treating lupus nephritis is a strategic campaign. The goal is to induce remission (stop the active attack) and then maintain remission (prevent it from coming back). Because the immune system is aggressive in lupus, the medications used are powerful. They are often drugs originally designed for chemotherapy or transplant rejection, repurposed to save the kidneys.
The treatment is highly personalized based on the biopsy “class.” What works for Class III might be useless for Class V. Follow-up is intensive. Patients become partners with their nephrology team, navigating side effects and celebrating improved lab numbers. It is a lengthy process that often necessitates years of maintenance therapy.
The first phase of treatment is called “induction.” This lasts for 3 to 6 months. The aim is to shut down the inflammation rapidly to save kidney tissue.
High-dose steroids (like prednisone or IV methylprednisolone) are the first line of defense. They act fast to reduce swelling and inflammation. While effective, they have significant side effects like weight gain, sleep issues, and high blood sugar. Doctors try to taper the dose down as quickly as it is safe to do so.
Along with steroids, a strong immunosuppressant is started.
Once the disease is quiet (remission), the “maintenance” phase begins. This can last for years. The goal is to prevent relapse using safer, lower doses of medication.
Patients usually continue on mycophenolate or switch to azathioprine (Imuran), which is safe for pregnancy. Steroids are often weaned off completely or kept at a very low dose. Stopping meds too early is the number one cause of relapse, so patience is key.
Science is advancing. New drugs specifically for lupus nephritis have been approved.
Beyond immunosuppressive drugs, protecting the kidney structure is vital. All patients are typically put on ACE inhibitors (like Lisinopril) or ARBs (like Losartan).
These blood pressure pills have a special superpower: they lower the pressure inside the kidney filters. This mechanical effect directly reduces protein leakage and slows down scarring. They are used even if blood pressure is normal, solely for kidney protection.
This is the “anchor” drug for all lupus patients. Unless there is a specific allergy, every patient with lupus nephritis should be on hydroxychloroquine. It is a mild immune modulator that prevents flares, reduces kidney damage, and protects the heart. It is the background insurance policy for the treatment plan.
Monitoring is frequent. During induction, labs are checked monthly. Doctors look at:
Treatment comes with costs. Steroids can cause bone thinning, so vitamin D and calcium are prescribed. Immunosuppressants increase infection risk, so preventive antibiotics (like Bactrim) might be used. Doctors actively manage these side effects to keep the patient healthy enough to stay on the life-saving kidney meds.

Cyclophosphamide can cause hair thinning, but it usually grows back. CellCept rarely causes hair loss. Lupus itself can cause hair loss during flares.
CellCept and Cytoxan cause birth defects. You must switch to pregnancy-safe drugs (like azathioprine) and be in remission for 6 months before conceiving.
The goal is to get off them as soon as possible, ideally within 6 months to a year, but some patients need a low dose longer to stay stable.
Remission means normal (or near normal) kidney function, little to no protein in the urine, and no active symptoms.
No herbal remedy can stop the immune attack of lupus nephritis. However, a healthy diet and stress management support the medical treatment.
