Living with Lupus Nephritis

What is Lupus Nephritis?

The American College of Rheumatology (ACR) classifies this disorder based on specific criteria such as proteinuria (protein in the urine) and the presence of urinary cellular casts.

Who is at Risk?

Both children and adults with lupus can develop lupus nephritis. However, certain groups are more prone to this condition:

Men are more likely to develop lupus nephritis
  • While women between the ages of 15 and 44 are more likely to develop lupus, men are more likely to develop lupus nephritis.
  • People of Black, Native American, Hispanic/Latino, Pacific Islander, or Asian descent are at a higher risk.
  • Exposure to specific infections, viruses, toxic chemicals, or environmental pollutants can increase susceptibility.
  • A family history of lupus or other autoimmune diseases can also elevate the risk.

Diagnosing Lupus Nephritis

urine test, blood tests, and kidney biopsy - diagnosis for lupus nephritis
  • Urine Test: A high amount of protein or a high number of red blood cells in the urine indicates kidney damage. Microscopic examination of the urine looks for kidney cells.
  • Blood Test: Checking the levels of creatinine and eGFR to measure kidney function. Other tests may include checking for specific antibodies such as anti-phospholipids and anti-nuclear antibodies (ANA).
  • Kidney Biopsy: For determining the extent of the disease and confirming the diagnosis.

Treatment Options

  • Corticosteroids: Often prednisone, to reduce swelling and inflammation.
  • Immunosuppressive Drugs: Such as cyclophosphamide or mycophenolate mofetil, which help to suppress the overactive immune response.
  • Hydroxychloroquine: This medication is specifically used for systemic lupus erythematosus (SLE) to manage symptoms.
  • Blood Pressure Medications: These include ACE inhibitors, ARBs, diuretics, beta-blockers, and calcium channel blockers, which help manage high blood pressure, a common complication of this autoimmune disease.

Dietary Recommendations

Sodium restricted diet for lupus nephritis

Managing lupus nephritis involves paying attention to diet. Patients are typically encouraged to limit their sodium intake to help manage blood pressure. It’s beneficial to collaborate with a dietitian to create a nutritious eating plan that promotes kidney health.

Potential Complications

Without proper diagnosis and treatment, this disorder can lead to severe complications, including kidney failure. Approximately 10 to 30 percent of individuals with this disorder may develop kidney failure, requiring dialysis or a kidney transplant. Other potential complications include increased risks of cancer (especially B-cell lymphoma) and cardiovascular problems.

Pregnancy and Lupus Nephritis

Women with this disorder face higher risks during pregnancy, including preeclampsia, premature labour, and lupus flares. Monitoring and managing this disease carefully during pregnancy is crucial for the health of both the mother and the baby.

Living with Lupus Nephritis

Effectively managing this disorder involves consistently taking medications, making lifestyle adjustments, and attending regular medical appointments. Patients must maintain close communication with healthcare providers to monitor their condition closely and make any necessary treatment modifications.
