The most common immunosuppressives for lupus include:
Data from people who continually treated their lupus with Benlysta ... to respond well to the treatment and had greater rates of infection. The findings suggest that assessing B cell and IgG levels before starting long-term use of Benlysta may help ...
Lupus anticoagulants (LAs) are a type of antibody produced by your body's immune system. While most antibodies attack disease in the body, LAs attack healthy cells and cell proteins. They attack phospholipids, which are essential components of cell membranes.
SLE is suspected based on signs and symptoms and confirmed using the ANA test profile. Conversely, lupus anticoagulant ( LA ) is plasma antibody that reacts with phospholipid-bound proteins, especially a plasma protein called β-2-glycoprotein I.

If a patient's blood contains an antiphospholipid antibody (aPL), it will bind to phospholipids in a test tube, and the blood will not clot. Although a positive test is called “lupus anticoagulant,” the name comes from its confused history.
Approximately 50% of people with lupus possesses these antibodies, and over a twenty-year period of time, one half of lupus patients with one of these antibodies—the lupus anticoagulant—will experience a blood clot. People without lupus can also have antiphospholipid antibodies.
[6][7] These immunoglobins may develop spontaneously due to medications, infections, or as a consequence of autoimmune diseases such as lupus erythematosus. [8] Infections such as EBV, syphilis, and hepatitis C increase the likelihood of acquired lupus anticoagulant.
It is recommended that two tests be used to detect lupus anticoagulant initially (known as LA-Screen). The most sensitive tests are dilute Russell viper venom test (DRVVT) and a LA-sensitive PTT (PTT-LA), one that uses reagents containing low levels of phospholipid.
People without lupus can also have antiphospholipid antibodies. The most commonly discussed antiphospholipid antibodies are the lupus anticoagulant (LA) and anticardiolipin antibody (aCL). These two antibodies are often found together, but can also be detected alone in an individual.
But there are four kinds of lupus:Systemic lupus erythematosus (SLE), the most common form of lupus.Cutaneous lupus, a form of lupus that is limited to the skin.Drug-induced lupus, a lupus-like disease caused by certain prescription drugs.Neonatal lupus, a rare condition that affects infants of women who have lupus.
People with lupus may develop Antiphospholipid Syndrome (APS), a condition that can cause blood clots and other health problems. APS is sometimes called Antiphospholipid Antibody Syndrome.
Antiphospholipid (AN-te-fos-fo-LIP-id) syndrome is a condition in which the immune system mistakenly creates antibodies that attack tissues in the body. These antibodies can cause blood clots to form in arteries and veins. Blood clots can form in the legs, lungs and other organs, such as the kidneys and spleen.
What causes antiphospholipid syndrome? APS is an autoimmune condition. This means the immune system, which usually protects the body from infection and illness, attacks healthy tissue by mistake. In APS, the immune system produces abnormal antibodies called antiphospholipid antibodies.
