How can my daughter safely manage lupus nephritis?

Question

Hello doctor,

I am reaching out regarding my 31-year-old daughter, who was diagnosed with lupus nephritis two years ago following proteinuria detected during a routine pregnancy checkup. She unfortunately lost that pregnancy at 22 weeks, and her physicians indicated the loss was likely related to kidney damage from lupus.

Her kidney biopsy revealed class IV lupus nephritis with severe inflammation. She has been on Mycophenolate mofetil (1,500 mg twice daily) and Prednisone (20 mg daily), but her kidney function continues to decline; her creatinine has risen from 0.9 last year to 2.1 mg/dL. Proteinuria remains significant at 3.8 g/day despite current treatment.

Her rheumatologist recently added Hydroxychloroquine, but she is experiencing persistent gastrointestinal discomfort and nausea. Prednisone has caused substantial side effects, including weight gain, facial rounding, and widespread stretch marks.

She is very eager to have another child, but her doctors emphasize that her lupus nephritis needs better control before pregnancy can be considered. Last year, she tried cyclophosphamide infusions, but her white blood cell count dropped too low. Additionally, her blood pressure has been rising to 145/92 mmHg despite two medications, and we are concerned about the potential need for dialysis.

We are seeking guidance on whether there are newer or alternative treatments for lupus nephritis that may be more effective or better tolerated, and whether a safe pregnancy is possible in her situation.

Thank you very much for your time and guidance.

Hi,

Welcome to icliniq.com

I am so sorry for what your daughter and family are going through. With class IV lupus nephritis, rising creatinine (0.9 to 2.1 mg/dL), and nephrotic-range proteinuria (3.8 g/day), despite mycophenolate and prednisone, it is reasonable to explore newer, more effective "steroid-sparing" options and reassess whether her kidneys are still actively inflamed versus having permanent scarring.

Continuous proteinuria and rising creatinine levels indicate active nephritis, which may necessitate stronger or modified immunosuppressive medication. Chronic scarring from past inflammation may reduce the effectiveness of immunosuppression, in which case the emphasis changes to kidney protection. It is also critical to discuss prescription issues such as dose, adherence, gastrointestinal tolerance, and drug interactions. Other renal processes that should be evaluated include thrombotic microangiopathy, antiphospholipid-related damage, and uncontrolled hypertension.

Before deciding on additional treatment, a repeat kidney biopsy can assist in identifying curable active inflammation from irreversible scarring, directing the pharmaceutical selection process.

Regarding modern treatments:

Belimumab (Benlysta) is a biologic that has improved kidney outcomes in people who have chronic proteinuria after routine treatment. The suitability of the treatment is determined by the biopsy results and the overall lupus activity.
Calcineurin inhibitors, such as Voclosporin (Lupkynis), can be beneficial, they may elevate blood pressure.
Anti-CD20 treatments, such as Rituximab or Obinutuzumab, are considered when other alternatives fail, based on biopsy results.
After her lupus nephritis is under control and her body has recovered from intense therapy, she can safely consider pregnancy again. For the time being, the primary focus is on stabilizing kidney function and managing disease activity.

I hope this helps.

Thank you.
