Not necessarily. The antinuclear antibody (ANA) test is positive in most people who have lupus, but it also may be positive in many people who are healthy or have another autoimmune disease. Therefore, a positive ANA test alone is not adequate for the diagnosis of lupus. There must be at least three additional clinical features from the list of 11 features for the diagnosis to be made.
In healthy people, eosinophils comprise approximately 1 to 6 percent of white blood cells. The body may produce more of these cells in response to parasitic and fungal infections. Certain allergic diseases, skin conditions, autoimmune disorders, cancers, and bone marrow diseases also may result in elevated eosinophil counts. Many people with eosinophilic disorders have high numbers of eosinophils in their blood or tissues over a long period of time. Sometimes, the presence of excess eosinophils in tissue, called “eosinophilic inflammation,” can result in tissue damage.
A primary lymphoid organ located in the mediastinal cavity anterior to and above the heart, where it lies over the superior vena cava, aortic arch, and trachea. The thymus comprises two fused lobes, the right larger than the left. The lobes are partially divided into lobules, each of which has an outer cortex packed with immature and developing T lymphocytes (thymocytes) and an inner medulla containing a looser arrangement of mature T lymphocytes.
SLE is an autoimmune disease involving multiple organ systems, a clinical pattern of flares and remissions, and the presence of anti-nuclear autoantibodies. Whereas early symptoms most frequently involve the skin and joints, disease morbidity and mortality are usually associated with cardiovascular events and damage to major organs, particularly the kidneys. Many of the current therapeutic options are considered to be inadequate because of toxicities, accrual of organ damage, and insufficient control of the underlying disease pathology. Improved understanding of SLE pathogenesis and immunology has led to the identification of new treatment targets. Current interest is mainly focused on the targeted immunosuppressive actions provided by biologic therapy. Although the potential long-term beneficial or harmful effects of the new molecular treatments are unclear, their precise molecular targeting may reveal key relationships within the immune system and advance the cause of individualized molecular medicine.
Recent research has found an association between certain people with lupus (especially those with lupus nephritis) and an impairment in degrading neutrophil extracellular traps (NETs). These were due to DNAse1 inhibiting factors, or NET protecting factors in people's serum, rather than abnormalities in the DNAse1 itself. DNAse1 mutations in lupus have so far only been found in some Japanese cohorts.
If you or a loved one has been diagnosed with the autoimmune disease systemic lupus erythematosus or any of the less common subtypes of lupus, you may be wondering about available treatment options and which ones may be right for you. Because lupus is a chronic disease, doctors work with you to manage symptoms — which can range from mild arthritis and rash to problems with the kidneys and other organs — using a variety of medications and therapies. And the best treatment approach for you might change over time as your symptoms and the condition changes.
