The body’s tolerance of the antigens present on its own cells, i.e., autoantigens or self-antigens. It is theorized that autoreactive T lymphocytes are destroyed in the thymus by negative selection or in peripheral blood. Autoreactive T cells that escape destruction in the thymus may become tolerant because they are exposed to thousands of autoantigens as they circulate in the blood.
To unravel which people with positive ANA tests actually have lupus, additional blood work can be done. Doctors look for other potentially troublesome antibodies, so they will test for anti-double-stranded DNA and anti-Smith antibodies. These tests are less likely to be positive unless a patient truly has lupus. However, a person who has negative test results could still have lupus, even though this is not so in the case of ANA tests.

With the vast amount of misinformation available online, Gibofsky often sees patients who went on restrictive diets that are purported to reduce lupus symptoms, which they may have read about on the internet or heard about from a neighbor. “Upon further discussion, I find that they do not actually feel better on the diet and, in fact, they have multiple nutritional deficiencies that could actually be the reason behind their worsening symptoms,” she said.
In recent years, mycophenolate mofetil (CellCept) has been used as an effective medication for lupus, particularly when it is associated with kidney disease. CellCept has been helpful in reversing active lupus kidney disease (lupus renal disease) and in maintaining remission after it is established. Its lower side-effect profile has advantage over traditional immune-suppression medications.
Corticosteroids. Prednisone and other types of corticosteroids can counter the inflammation of lupus. High doses of steroids such as methylprednisolone (A-Methapred, Medrol) are often used to control serious disease that involves the kidneys and brain. Side effects include weight gain, easy bruising, thinning bones (osteoporosis), high blood pressure, diabetes and increased risk of infection. The risk of side effects increases with higher doses and longer term therapy.
