B cells obtain help from T cells in the antibody response by acting as antigen-specific antigen presenting cells. A direct signal through binding of antigen to membrane Ig can enhance B cell antigen presentation and T-dependent B cell activation, but is not required for a productive interaction between a small resting B cell and a differentiated helper T cell.
Painless passage of blood or protein in the urine may often be the only presenting sign of kidney involvement. Acute or chronic renal impairment may develop with lupus nephritis, leading to acute or end-stage kidney failure. Because of early recognition and management of SLE, end-stage renal failure occurs in less than 5% of cases; except in the black population, where the risk is many times higher.
Immunosuppressive Medications Immunosuppressives are medications that help suppress the immune system. Many were originally used in patients who received organ transplants to help prevent their bodies from rejecting the transplanted organ. However, these drugs are now also used for the treatment of certain autoimmune diseases, such as lupus and rheumatoid arthritis.
A large randomized trial that compared induction therapy consisting of oral mycophenolate mofetil with cyclophosphamide therapy in patients with lupus nephritis showed that mycophenolate mofetil was not inferior to cyclophosphamide.  The investigators suggested that mycophenolate mofetil was associated with both a trend toward greater complete remissions and a greater safety profile.  This study’s findings were confirmed with the large, international Aspreva Lupus Management Study (ALMS) trial. 
Other medicines. You may need other medicines to treat illnesses or diseases that are linked to your lupus — such as high blood pressure or osteoporosis. Many people with lupus are also at risk for blood clots, which can cause a stroke or heart attack. Your doctor may prescribe anticoagulants (“blood thinners”), such as warfarin or heparin, to prevent your blood from clotting too easily. You cannot take warfarin during pregnancy.
These conditions may be treated with high-dose intravenous steroids and cytotoxic therapy such as cyclophosphamide. Strokes, acute myocardial infarctions, and pulmonary emboli occurring as complications of SLE are managed in the same way as they are in patients without SLE. In patients who present with fever, it may be necessary to limit immunosuppression to steroids and to empirically treat for an infection until culture results have been received.
A diet high in omega-3 fatty acids may help to mitigate inflammation. Although omega-3s have not been adequately studied in lupus, studies of the general population suggest that these essential fatty acids may also boost mood and improve cardiovascular health. Fish, nuts, and flax are excellent sources of omega-3s and can be easily incorporated into everyday meals. Try to avoid saturated fats, such as those in beef and fried snack foods, since these fats are known to increase the risk of cardiovascular disease and may actually stimulate the immune system.
The severity of lupus varies from mild to life threatening. Kidney problems and neurologic complications are more dangerous than the rashes, arthritis or other symptoms. After many years of having lupus, patients may develop hypertension (high blood pressure), accelerated atherosclerosis (plaque and fat build-up in the arteries), heart and lung diseases, kidney failure or osteoporosis. With proper treatment, the majority of people diagnosed with lupus have a normal life expectancy, but many will experience disabilities. Each patient will likely have his or her own specific pattern of symptoms and flares, but the disease can change over time.
Soy products. Soy products are high in a type of estrogen called phytoestrogen, and estrogen is known to be a risk factor for lupus. In animal studies, researchers noted that a diet high in soy seemed to make lupus symptoms worse. Although there is no definitive evidence that soy products cause lupus symptoms, you should be cautious about including large amounts of soy in your diet.
Your kidneys are two bean-shaped organs, each about the size of your fists. They are located near the middle of your back, just below the rib cage. Inside each kidney about a million tiny structures called nephrons filter blood. They remove waste products and extra water, which become urine. The urine flows through tubes called ureters to your bladder, which stores the urine until you go to the bathroom. Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines.
When lupus starts affecting other organs of the body, doctors often prescribe drugs that suppress the immune system, says Kramer. (Lupus causes the body’s immune system to mistakenly attack itself. Immunosuppressive medications help stop that from happening.) One such example, is Cytoxan (cyclophosphamide), originally an anticancer drug. It suppresses the immune system and may be used to reduce inflammation of the kidney, or nephritis, says Dr. Kaplan.
