Any of a group of glycoproteins with antiviral activity. The antiviral type I interferons (alpha and beta interferons) are produced by leukocytes and fibroblasts in response to invasion by a pathogen, particularly a virus. These interferons enable invaded cells to produce class I major histocompatibility complex surface antigens, increasing their ability to be recognized and killed by T lymphocytes. They also inhibit virus production within infected cells. Type I alpha interferon is used to treat condyloma acuminatum, chronic hepatitis B and C, and Kaposi’s sarcoma. Type I beta interferon is used to treat multiple sclerosis. Type II gamma interferon is distinctly different from and less antiviral than the other interferons. It is a lymphokine, excreted primarily by CD8+ T cells and the helper T subset of CD4+ cells that stimulates several types of antigen-presenting cells, particularly macrophages, to release class II MHC antigens that enhance CD4+ activity. It is used to treat chronic granulomatous disease.

A mononuclear phagocytic white blood cell derived from myeloid stem cells. Monocytes circulate in the bloodstream for about 24 hr and then move into tissues, at which point they mature into macrophages, which are long lived. Monocytes and macrophages are one of the first lines of defense in the inflammatory process. This network of fixed and mobile phagocytes that engulf foreign antigens and cell debris previously was called the reticuloendothelial system and is now referred to as the mononuclear phagocyte system (MPS).
"Keeping my weight under control has been a battle. I have tried diets. I know that being overweight increases joint stress and stress on my heart, both of which can be affected by lupus," says LaPlant. Some of the medications that people take for lupus can make it difficult to maintain a healthy weight. Prednisone, one of the most common medications used to treat lupus flares, can increase your appetite and lead to significant weight gain. Regular, low-impact exercise can help offset weight gain and also improve your health in general.
Anitphospholipid Antibodies (APLs): Phospholipids are antibodies that are present in approximately one out of every two people with lupus.  A positive test can help confirm diagnosis as well as help identify women with lupus who have certain risks (like blood clots and miscarriage) that would require preventative treatment and monitoring. Note that the presence of phospholipids also occurs in people without lupus and therefore, there presence alone is not enough for a lupus diagnosis.
Peer review is the first stage of our grant decision-making process. All applications received are reviewed by top experts in the field, to determine whether or not those studies show great promise. After all, we only want to scrutinize the best projects most carefully. This crucial first step allows only the projects that have tremendous scientific merit and hold great promise for preventing, treating, and curing lupus, to advance to the second stage of the review process. That second stage is a process managed by our Scientific Advisory Board, where they take all of the top scoring applications, scrutinize them very carefully, and then make recommendations to our Board of Directors, for which ones we are actually going to fund.

A biopsy is a procedure that removes a small piece of living tissue from your body. The tissue is examined with a microscope for signs of damage or disease. Biopsies can be done on all parts of the body. A biopsy is the only test that can tell for sure if a suspicious area is cancer. But biopsies are performed for many other reasons too. There are different ways to do a biopsy. A needle biopsy removes tissue with a needle passed through your skin to the site of the problem. Other kinds of biopsies require surgery.
In addition to the 11 criteria, other tests can be helpful in evaluating people with SLE to determine the severity of organ involvement. These include routine testing of the blood to detect inflammation (for example, the erythrocyte sedimentation rate, or ESR, and the C-reactive protein, or CRP), blood-chemistry testing, direct analysis of internal body fluids, and tissue biopsies. Abnormalities in body fluids (joint or cerebrospinal fluid) and tissue samples (kidney biopsy, skin biopsy, and nerve biopsy) can further support the diagnosis of SLE. The appropriate testing procedures are selected for the patient individually by the doctor.
The GRADE approach was followed in the process ( answering the clinical questions voted most relevant by the panel. The description of the methodology followed to develop these guidelines has already been published.29 All authors listed in this manuscript have participated in planning, drafting, reviewing, final approval and are accountable for all aspects of the manuscript. No ethical approval was required by institutions. We present the final recommendations and their supporting information. Comments from three patients with SLE were also considered.

Avoid foods that cause food sensitivities or allergies. You must be tested for this in order to be sure of your bodies specific needs. Some tests do not indicate food sensitivities (such as to sugar, salt, etc.), so keep a journal of your body's reactions to foods. Eat a varied diet, rich with alkaline, antioxidant, anti-inflammatory foods. Always clean your food well, (including organic foods).
Researchers have made great progress in identifying people at-risk for lupus and the molecular markers (something found in cells that can predict lupus flares) that appear before the onset of symptoms. From these advances, scientists hope to generate early-intervention or even disease-prevention strategies. For people with established lupus, research is focused on designing new clinical trials that test drug candidates, which, if successful, could be combined with existing therapies. The Lupus Research Alliance is funding the most innovative research in the world, with the hope of finding better diagnostics, improved treatment and, eventually, a cure.
“It’s always difficult for children and parents to live with the idea that lupus is chronic,” says Pascual. That means the child has many more years worth of living with the condition than if he or she were diagnosed later in life. And because this disease is lifelong and may involve complications such as nephritis, doctors need to manage it aggressively.
A normal-range ANA titer in the context of organ system involvement that suggests systemic lupus erythematosus should prompt a work-up for alternative diagnoses. If no other cause is identified, the diagnosis of ANA-negative systemic lupus erythematosus and consultation with a rheumatologist should be considered. If patients with a normal ANA titer develop new clinical features that are consistent with systemic lupus erythematosus, ANA testing should be repeated.46 [Evidence level C, consensus/expert guidelines]
Disease-modifying antirheumatic drugs (DMARDs) are used preventively to reduce the incidence of flares, the progress of the disease, and the need for steroid use; when flares occur, they are treated with corticosteroids. DMARDs commonly in use are antimalarials such as hydroxychloroquine and immunosuppressants (e.g. methotrexate and azathioprine). Hydroxychloroquine is an FDA-approved antimalarial used for constitutional, cutaneous, and articular manifestations. Hydroxychloroquine has relatively few side effects, and there is evidence that it improves survival among people who have SLE.[83] Cyclophosphamide is used for severe glomerulonephritis or other organ-damaging complications. Mycophenolic acid is also used for treatment of lupus nephritis, but it is not FDA-approved for this indication, and FDA is investigating reports that it may be associated with birth defects when used by pregnant women.[86]
The complement system is the name of a group of blood proteins that help fight infection. Complement levels, as the name implies, measure the amount and/or activity of those proteins. Working within the immune system, the proteins also play a role in the development of inflammation. In some forms of lupus, complement proteins are consumed (used up) by the autoimmune response. A decrease in complement levels can point toward lupus nephritis, lupus nephritis, kidney inflammation. Normalization of complement levels can indicate a favorable response to treatment.
One common early symptom that can be indicative of lupus is a photosensitive rash, meaning a rash that develops in response to sun exposure, particularly on the face and upper arms, says Dr. Kramer. Other early symptoms are unexplained fever and pain, swelling, and stiffness of multiple joints. Complications such as inflammation of the lining surrounding the lungs or heart can also occur early on, he adds.
The classical period began when the disease was first recognized in the Middle Ages. The term lupus is attributed to 12th-century Italian physician Rogerius Frugard, who used it to describe ulcerating sores on the legs of people.[107] No formal treatment for the disease existed and the resources available to physicians to help people were limited.[108]
A clinical trial is a prospective biomedical or behavioral research study of human subjects that is designed to answer specific questions about biomedical or behavioral interventions (drugs, treatments, devices, or new ways of using known drugs, treatments, or devices). Clinical trials are used to determine whether new biomedical or behavioral interventions are safe, efficacious, and effective.

Lupus is chronic, complex, and difficult to diagnose. No single lab test can tell if you have lupus. Many lupus symptoms imitate symptoms of other diseases and often come and go. Your primary care doctor or rheumatologist will use your medical history, a physical exam, and many routine as well as special tests to rule out other diseases. Many physicians also use the American College of Rheumatology's "Eleven Criteria of Lupus" to aid in the diagnosis of lupus. The criteria include symptoms as well as specific laboratory findings that provide information about the functioning of a person's immune system. In most cases, the diagnosis of lupus is made when four or more of the criteria have occurred at some time.
The cause of SLE is not clear.[1] It is thought to involve genetics together with environmental factors.[4] Among identical twins, if one is affected there is a 24% chance the other one will be as well.[1] Female sex hormones, sunlight, smoking, vitamin D deficiency, and certain infections, are also believed to increase the risk.[4] The mechanism involves an immune response by autoantibodies against a person's own tissues.[1] These are most commonly anti-nuclear antibodies and they result in inflammation.[1] Diagnosis can be difficult and is based on a combination of symptoms and laboratory tests.[1] There are a number of other kinds of lupus erythematosus including discoid lupus erythematosus, neonatal lupus, and subacute cutaneous lupus erythematosus.[1]
The cause of lupus remains unknown, but there is solid evidence that genetics, epigenetics (changes in chromosomes that affect gene activity), environmental factors, viruses and infections play a role. Further study of these variables is expected to improve our understanding of causes, which should lead to improved diagnosis, prognosis, prevention, and treatment.

The panel suggests SOC alone over adding other immunosuppressant (IS) in adult patients with SLE with MSK manifestations (weak recommendation based on low certainty of the evidence). It suggests also adding either MTX, LFN, belimumab or ABT to those failing to respond to SOC (weak recommendation based on low to moderate certainty of the evidence). Cost and availability may favour MTX (table 1).
Microbial metabolomics constitutes an integrated component of systems biology. By studying the complete set of metabolites within a microorganism and monitoring the global outcome of interactions between its development processes and the environment, metabolomics can potentially provide a more accurate snap shot of the actual physiological state of the cell.
The modern period, beginning in 1920, saw major developments in research into the cause and treatment of discoid and systemic lupus. Research conducted in the 1920s and 1930s led to the first detailed pathologic descriptions of lupus and demonstrated how the disease affected the kidney, heart, and lung tissue.[115] A major breakthrough was made in 1948 with the discovery of the LE cell (the lupus erythematosus cell—a misnomer, as it occurs with other diseases as well). Discovered by a team of researchers at the Mayo Clinic, they discovered that the white blood cells contained the nucleus of another cell that was pushing against the white's cell proper nucleus.[116] Noting that the invading nucleus was coated with antibody that allowed it to be ingested by a phagocytic or scavenger cell, they named the antibody that causes one cell to ingest another the LE factor and the two nuclei cell result in the LE cell.[117] The LE cell, it was determined, was a part of an anti-nuclear antibody (ANA) reaction; the body produces antibodies against its own tissue. This discovery led to one of the first definitive tests for lupus since LE cells are found in approximately 60% of all people diagnosed with lupus.[118] The LE cell test is rarely performed as a definitive lupus test today as LE cells do not always occur in people with SLE and can occur in individuals with other autoimmune diseases. Their presence can be helpful in establishing a diagnosis but no longer indicates a definitive SLE diagnosis.
Decorin is a protein coded for by the DCN gene. This protein is a component of the extracellular matrix, which is the intricate lattice of proteins and other molecules that forms in the spaces between cells. Decorin is found in the extracellular matrix of a variety of connective tissues, including skin, tendon, bone, and cartilage. Connective tissues support the body’s joints and organs. Decorin is involved in the organization of proteins called collagens. Collagens strengthen and support connective tissues throughout the body. Collagens also play an important role in the cornea, which is the clear outer covering of the eye. Bundles of collagen called fibrils must be strictly organized for the cornea to be transparent. Decorin ensures that these collagen fibrils are uniformly sized and regularly spaced.

Immunosuppressive agents/chemotherapy. In advanced cases of lupus, drugs like azathioprine, methotrexate and cyclophosphamide might be used to suppress the immune system. These types of therapies can help prevent organ damage; however, they do cause severe side effects as well as infertility in women. People on immunosuppressive therapies must be closely monitored by a doctor.
Mercury is toxic to our bodies and can be one piece of the puzzle for those with lupus and other chronic illnesses such as chronic fatigue syndrome, other autoimmune diseases, neurological disorders, and cancer. Mercury overload is far more common than many people think. We’re exposed to mercury in our air and water, the fish we eat, amalgam fillings, cosmetics, and vaccines. I recommend heavy metal testing for all of my patients with autoimmunity, using a pre- and post-DMPS urine challenge test. I also recommend that anyone with mercury amalgam fillings find a biological dentist and have them removed.

SLE is undoubtedly a potentially serious illness with involvement of numerous organ systems. However, it is important to recognize that most people with SLE lead full, active, and healthy lives. Periodic increases in disease activity (flares) can usually be managed by varying medications. Since ultraviolet light can precipitate and worsen flares, people with systemic lupus should avoid sun exposure. Sunscreens and clothing covering the extremities can be helpful. Abruptly stopping medications, especially corticosteroids, can also cause flares and should be avoided. People with SLE are at increased risk of infections as SLE-related complications, especially if they are taking corticosteroids or immunosuppressive medications. Therefore, any unexpected fever should be reported to medical professionals and evaluated.
Saturated fats, on the other hand, can raise cholesterol levels and may contribute to inflammation. So they should be limited. Sources of saturated fats include fried foods, commercial baked goods, creamed soups and sauces, red meat, animal fat, processed meat products, and high-fat dairy foods. That includes whole milk, half and half, cheeses, butter, and ice cream.
Lupus takes a long time to diagnose and all the emotional elements of dealing with other peoples misunderstanding adds to the negative feelings. There is really no way to avoid this, just know that you’re not alone in this. My wife has been dealing with Lupus for 30 years and yes there have been difficult times and doctors without understanding or empathy.
Why the test is used: Anti-Ro is found in anywhere from 24% to 60% of lupus patients. It's also found in 70% of people with another autoimmune disorder called Sjögren's syndrome. Anti-La is found in 35% of people with Sjögren's syndrome. For this reason, their presence may be useful in diagnosing one of these disorders. Both antibodies are associated with neonatal lupus, a rare but potentially serious problem in newborns. In pregnant women, a positive Anti-Ro(SSA) or Anti-La(SSB) warns doctors of the need to monitor the unborn baby.
Lupus nephritis is managed with a combination of glucocorticoids [130] and immunosuppressive agents to slow the progression to end-stage renal disease (ESRD), along with maintaining normal blood pressure levels (ie, target of ≤130/80 mm Hg). [61, 96] In general, individuals with class I or II lupus nephritis do not need management with immunosuppression. [96]
Maybe. Start by seeing your family doctor and a rheumatologist, a doctor who specializes in the diseases of joints and muscles such as lupus. Depending on your symptoms or whether your organs have been hurt by your lupus, you may need to see other types of doctors. These may include nephrologists, who treat kidney problems, and clinical immunologists, who treat immune system disorders.
Moderate use of alcohol is usually not a problem for people with lupus, but alcohol can lower the effectiveness of some medications, cause new health problems, and/or can make existing problems worse. For example, non-steroidal anti-inflammatory drugs -- such as aspirin, ibuprofen (Motrin®), naproxen (Naprosyn®), and celecoxib (Celebrex®) -- can cause ulcers and bleeding in the stomach and intestines at any time during treatment; the chance of developing an ulcer or internal bleeding increases with alcohol use. Also, anticoagulant medicines such as warfarin (Coumadin®) and the chemotherapy drug, methotrexate, may not be as effective if you are drinking alcohol.
Recommendations are applicable to patients showing partial or total remission after induction therapy aiming at sustaining renal remission, preventing relapses and achieving the best long-term outcome. The following interventions were considered: (1) AZA; (2) MMF; (3) CYC; (4) TAC; and (5) CsA (online supplementary tables S1.1.1.7, S1.1.2.1, S1.1.2.2, S1.2.1, S1.2.3, S1.2.4, S1.2.5, S1.2.6, S1.2.7).

An increase in the size of an organ, structure, or the body due to growth rather than tumor formation. This term is generally restricted to an increase in size or bulk that results not from an increase in the number of cells but from an increase in a cellular component, e.g., proteins. It applies to any increase in size as a result of functional activity.
These foods are not helpful and most of them contribute to raising the risk of coronary heart disease; there is an increased risk of this in people with lupus, so you will protect yourself by reducing the amount of these you consume. The recommended daily amount of salt should not be more than six grams, which is approximately one teaspoonful; many processed foods are highly salted which means that it’s really easy to exceed this amount. Instead of seasoning your food with salt, try using lemon juice or herbs to enhance its flavour.
Rates of positive ANA tests are affected by the prevalence of systemic lupus erythematosus in the population. Specifically, false-positive rates will be higher in populations with a low prevalence of the disease, such as primary care patients. Because of the high false-positive rates at 1:40 dilution, ANA titers should be obtained only in patients who meet specific clinical criteria (discussed in the clinical recommendations section of this article). When ANA titers are measured, laboratories should report ANA levels at both 1:40 and 1:160 dilutions and should supply information on the percentage of normal persons who are positive at each dilution.41
Cardiac tamponade is pressure on the heart that occurs when blood or fluid builds up in the space between the heart muscle (myocardium) and the outer covering sac of the heart (pericardium). This prevents the heart ventricles from expanding fully. The excess pressure from the fluid prevents the heart from working properly. As a result, the body does not get enough blood.
For each of the subheadings listed below, the panel considered interventions based on experience, availability, affordability and a stepwise therapeutic approach of the different alternatives. Standard of care (SOC) was defined as the use of hydroxychloroquine (HCQ) and, if clinically indicated, low-dose glucocorticoids (GC) (prednisone ≤7.5 mg or equivalent for the shortest time).24 Chloroquine remains an alternative for some of the Latin American countries where HCQ is not available and careful monitoring of eye side effect is recommended. Overarching principles are shown in box 1. Tables summarising the evidence that was considered in the process are shown in online supplementary tables in
There is no single test to definitively diagnose lupus, and it could take months or even years to be sure. Typically, your doctor will conduct a complete medical history and physical exam, including blood tests. The doctor may also perform skin and kidney biopsies (extracting tissue samples that are then examined under a microscope) to make a diagnosis.
Hydroxychloroquine (Plaquenil) is an antimalarial medication found to be particularly effective for SLE people with fatigue, skin involvement, and joint disease. Consistently taking Plaquenil can prevent flare-ups of lupus. Side effects are uncommon but include diarrhea, upset stomach, and eye-pigment changes. Eye-pigment changes are rare but require monitoring by an ophthalmologist (eye specialist) during treatment with Plaquenil. Researchers have found that Plaquenil significantly decreased the frequency of abnormal blood clots in people with systemic lupus. Moreover, the effect seemed independent of immune suppression, implying that Plaquenil can directly act to prevent the blood clots. This fascinating study highlights an important reason for people and doctors to consider Plaquenil for long-term use, especially for those SLE people who are at some risk for blood clots in veins and arteries, such as those with phospholipid antibodies (cardiolipin antibodies, lupus anticoagulant, and false-positive venereal disease research laboratory test). This means not only that Plaquenil reduces the chance for re-flares of SLE, but it can also be beneficial in thinning the blood to prevent abnormal excessive blood clotting. Plaquenil is commonly used in combination with other treatments for lupus.
A member of a group of enzymes that can break down proteins, such as collagen, that are normally found in the spaces between cells in tissues (i.e., extracellular matrix proteins). Because these enzymes need zinc or calcium atoms to work properly, they are called metalloproteinases. Matrix metalloproteinases are involved in wound healing, angiogenesis, and tumor cell metastasis.

The antinuclear antibody (ANA) test is used to detect autoantibodies that react against components of the nucleus of the body's cells. It's currently one of the most sensitive diagnostic tests available for diagnosing lupus (SLE). That's because 97 percent or more of people with lupus (SLE) have a positive ANA test result. A negative ANA test result means lupus (SLE) is unlikely. 

People with SLE need more rest during periods of active disease. Researchers have reported that poor sleep quality was a significant factor in developing fatigue in people with SLE. These reports emphasize the importance for people and physicians to address sleep quality and the effect of underlying depression, lack of exercise, and self-care coping strategies on overall health. During these periods, carefully prescribed exercise is still important to maintain muscle tone and range of motion in the joints.
The cause of lupus remains unknown, but there is solid evidence that genetics, epigenetics (changes in chromosomes that affect gene activity), environmental factors, viruses and infections play a role. Further study of these variables is expected to improve our understanding of causes, which should lead to improved diagnosis, prognosis, prevention, and treatment.

The following drugs are commonly used to treat the inflammation and symptoms of lupus. Since lupus manifests in different ways in different people, treatment regimens differ from patient to patient. In addition, one patient may experience several different treatment regimens during her/his lifetime. It is important that you understand the medications you are taking and the risks, benefits, and restrictions associated with them. Please remember to take your medications exactly as directed by your physician and to address any questions or concerns upon your next visit.
