How often should lupus nephritis be checked?

Question

Hello doctor,

I am a 32-year-old woman suffering from systemic lupus. I recently had a kidney biopsy and was diagnosed with early-stage lupus nephritis. My doctor has put me on immunosuppressive medicine, but I am worried about the long-term outlook, including the likelihood of needing dialysis or a transplant in the future.

What are the main symptoms and indicators that can suggest deteriorating renal function?
I would also like advice on how often follow-up laboratory tests, urine tests, and any necessary imaging examinations should be generally undertaken to assess illness progression and response to treatment.

Thank you for your time and advice.

Would really appreciate any recommendations you have.

Hello,

I hope you are doing well.

I completely understand your concerns.

Lupus nephritis can feel like a heavy burden, but the most important things to ensure good long-term outcomes are to keep consistent with your recommended therapy and to attend regular follow-up sessions. Close monitoring allows your health care team to spot indicators of disease activity early and alter your therapy swiftly, if necessary.

Treatment generally includes medications such as

Mycophenolate mofetil (usually up to 2 g/day, depending on your doctor’s recommendation)
Hydroxychloroquine (usually dosed at about 5 mg/kg/day), which are considered to be cornerstone therapies for many patients with lupus nephritis.
If you have high blood pressure or ongoing proteinuria, your doctor may additionally prescribe an ACE inhibitor such as Captopril to help limit protein loss in the urine and preserve kidney function.
If appropriate, your blood pressure treatment may be changed to add this medicine.

It is important that follow-up sessions should be conducted after every two to three months or as suggested by your nephrologist or rheumatologist.

The testing procedure will comprise the following steps:

The serum creatinine and glomerular filtration rate are among the tests used to check kidney function.
A urine test is done to measure the amount of protein in urine. This can be done by collecting all urine passed over 24 hours for urine protein or by determining the urine albumin-to-creatinine (or protein-to-creatinine) ratio

These tests are used to evaluate kidney function and to look for evidence of persistent inflammation.

Findings that may suggest increased lupus activity include:

Proteinuria greater than 500 mg/day.
Blood in the urine (hematuria).
Pyuria, which is characterized by an increase in white blood cells in the urine, is observed following the exclusion of infection.
Urinary casts (particularly red blood cell, granular, or cellular casts).
Rising anti-double-stranded DNA (anti-dsDNA) antibody levels.
Falling levels, particularly C3 and sometimes C4.

If these abnormalities develop, your treating physician may recommend additional evaluation, which can include a repeat kidney biopsy in selected cases to determine the degree of disease activity and guide further treatment.

In the comfort of your own home, check your blood pressure regularly, keeping an eye out for signs like swelling of your feet, ankles, or even swelling in the area around your eyes in the morning. It must be noted, however, that lupus nephritis does tend to progress asymptomatically in some cases, which is the reason why regular laboratory monitoring is vital.

Under proper treatment, regular monitoring, and prompt response to any disease flare-ups, many individuals living with lupus nephritis manage to protect their kidneys' functionality and minimize their chances of developing complications.

Stay healthy.

Do not hesitate to ask any questions you may have regarding lupus nephritis.

Thank you.
