Systemic lupus erythematosus (SLE) is an autoimmune disease found to play a role in lupus kidney disease and inflammation of the kidney. When lupus affects the kidneys it is known as lupus nephritis. This can result in kidney problems linked to kidney damage known as glomerulus.
Lupus glomerulonephritis (LGN), when lupus is associated with glomerulus damage, can range in severity and is detected with a biopsy. LGN occurs when antibodies and proteins build-up in the kidneys causing inflammation. A biopsy of the kidney can better help determine the type of LGN and better predict the course of the kidney damage.
Research has found that lupus nephritis is a common lupus complication affecting 38.3 percent of patients. Researchers have found that patients with lupus nephritis have a greater risk of end-stage renal disease and death. Furthermore, patients were more likely to be male, younger and of non-Caucasian ethnicity.
Dr. Kyriakos Kirou told Medscape Medical News, “One thing this study should emphasize is that people with lupus should be checked for lupus nephritis, and make sure they have regular follow-up if they do have lupus nephritis. It’s very important to treat early and aggressively. I don’t necessarily mean to give more medicine, but better follow-up.”
Researchers examined 1,827 newly diagnosed patients of lupus enrolled in the Systemic Lupus International Collaborating Clinics. Patients came form Europe, the U.S., Canada, Mexico and Asia and all received standard care.
Researchers found patients with lupus nephritis had more incidences of hypertension, serositis, neurological disorders, and immunological disorders, but they were less likely to have mucocutaneous disease, arthritis, and antinuclear antibodies. Lastly, patients with lupus nephritis had the lowest scores when it came to overall quality of life.
Symptoms associated with lupus nephritis can be mild and not appear dramatic. Initial symptoms of lupus nephritis can involve swelling of the legs, ankles and feet. Less common is swelling of the face or hands. Other symptoms of lupus nephritis include:
Lupus nephritis occurs in five stages, and the World Health Organization created a system to classify each one. Stages of lupus nephritis are:
Stage 1: no evidence of lupus nephritis present.
Stage 2: mild form, can be treated with corticosteroids.
Stage 3: early stage of advanced lupus, treatment with high doses of corticosteroids, outlook still favorable.
Stage 4: advanced stage of lupus, risk of kidney failure has increased, treatment involved high amounts of corticosteroids along with immune suppression medications.
Stage 5: excessive protein loss and swelling, treatment still possible with high amounts of corticosteroids, immune-suppressing drugs may not be given.
As always, diet can play a role in many conditions and lupus kidney disease is no different. Similar to patients with kidney disease, those with lupus kidney disease should avoid excess salt, stick with low protein, high calories and high vitamins. A diet in this style is less stressful on the kidneys.
On the other hand, there are foods that people with lupus kidney disease should avoid, including:
There are three main ways lupus nephritis is diagnosed which are:
Urinalysis: urine is collected in a special container where is it sent to a lab for testing.
Blood test: blood is drawn at a clinic and sent to a lab for further analysis. The blood will reveal levels of creatinine, which is the waste product of broken down muscle that becomes excreted from the kidneys.
Biopsy: a small tissue sample of the kidney is removed and analyzed. Not only will a biopsy diagnose lupus nephritis, but it can determine the progression of the disease as well.
Natural ways to treat lupus nephritis include:
In some cases a doctor may also recommend a low potassium diet if loss of kidney function has occurred. With proper treatment a patient can lower their risk of kidney failure related to lupus nephritis.
Inflammatory systemic autoimmune diseases, such as rheumatoid arthritis, lupus and Sjögren’s syndrome, have all been found to overlap. Lupus is an autoimmune disease that causes the immune system to produce antibodies that produce widespread inflammation all over the body and can result in tissue damage. Continue reading…
There are a number of chronic kidney disease risk factors, but a lot of nutritional research shows that a chronic kidney or CKD diet that takes sodium and potassium intake into careful consideration, can make a big difference in keeping kidneys healthy. Continue reading…
