The clearance of early apoptotic cells is an important function in multicellular organisms. It leads to a progression of the apoptosis process and finally to secondary necrosis of the cells if this ability is disturbed. Necrotic cells release nuclear fragments as potential autoantigens, as well as internal danger signals, inducing maturation of dendritic cells (DCs), since they have lost their membranes' integrity. Increased appearance of apoptotic cells also stimulates inefficient clearance. That leads to maturation of DCs and also to the presentation of intracellular antigens of late apoptotic or secondary necrotic cells, via MHC molecules. Autoimmunity possibly results by the extended exposure to nuclear and intracellular autoantigens derived from late apoptotic and secondary necrotic cells. B and T cell tolerance for apoptotic cells is abrogated, and the lymphocytes get activated by these autoantigens; inflammation and the production of autoantibodies by plasma cells is initiated. A clearance deficiency in the skin for apoptotic cells has also been observed in people with cutaneous lupus erythematosus (CLE).[67]
The first mechanism may arise genetically. Research indicates SLE may have a genetic link. SLE does run in families, but no single causal gene has been identified. Instead, multiple genes appear to influence a person's chance of developing lupus when triggered by environmental factors. HLA class I, class II, and class III genes are associated with SLE, but only classes I and II contribute independently to increased risk of SLE.[45] Other genes which contain risk variants for SLE are IRF5, PTPN22, STAT4,[46] CDKN1A,[47] ITGAM, BLK,[46] TNFSF4 and BANK1.[48] Some of the susceptibility genes may be population specific.[46]

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.
Inflammation of the heart muscle, usually in the U.S. as a consequence of infections (viruses, esp. coxsackie virus, and occasionally as a consequence of bacterial, protozoan or fungal infections); immunological-rheumatological conditions (e.g., systemic lupus erythematosus, ulcerative colitis, hypersensitivity reactions, or transplant rejection); exposure to chemicals or toxins (e.g., cocaine, doxorubicin, methamphetamine); nutritional or metabolic abnormalities (e.g., thiamine deficiency or hypophosphatemia); or radiation. Myocarditis also is occasionally found in pregnancy and with advanced age. The myocardium is infiltrated by leukocytyes, lymphocytes, and macrophages, leading to inflammation, necrosis of muscle cells, and fibrosis. Inflammatory damage to heart muscle fibers may resolve spontaneously or may cause progressive deterioration of the heart with pericarditis, arrhythmias, chronic dilated cardiomyopathy, and heart failure.
A lesion of the skin or mucous membranes marked by inflammation, necrosis, and sloughing of damaged tissues. A wide variety of insults may produce ulcers, including trauma, caustic chemicals, intense heat or cold, arterial or venous stasis, cancers, drugs (such as nonsteroidal anti-inflammatory drugs [NSAIDs]), and infectious agents such as Herpes simplex or Helicobact

Libman-Sacks endocarditis is the most characteristic cardiac manifestation of lupus. It is characterized by clusters of verrucae on the ventricular surface of the mitral valve. These lesions consist of accumulation of immune complexes, platelets, and mononuclear cells. This can lead to heart failure, valvular dysfunction, emboli, and secondary infective endocarditis. Diagnosis is best made via echocardiography, which may reveal the characteristic valvular masses (arrows). IVS = interventricular septum; LA = left atrium; LV = left ventricle.
Most people who have SLE have low levels of vitamin D and should take a vitamin D supplement regularly. Vitamin D is essential for proper function of the immune system and several studies have shown that people who have more severe lupus tend to have lower levels of vitamin D compared to those who have milder disease.  It is advised to talk with your consultant or GP about your vitamin D levels as you may already be prescribed calcium supplements which may contain vitamin D. Some dietary sources of vitamin D can be found HERE. It is important to bear in mind that most vitamin D is usually synthesised from sunlight on the skin, but with lupus you should be protecting yourself from exposure to UV.
In addition to prescribing medications, doctors may also recommend lifestyle changes to help manage lupus. These may include avoidance of sun exposure and paying more attention to managing stress to prevent lupus flares (periods of time when symptoms become problematic). People with lupus should also avoid smoking to help with heart and lung health, Kramer says.
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.
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.
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.
Neuropsychiatric syndromes can result when SLE affects the central or peripheral nervous system. The American College of Rheumatology defines 19 neuropsychiatric syndromes in systemic lupus erythematosus.[30] The diagnosis of neuropsychiatric syndromes concurrent with SLE (now termed as NPSLE),[31] is one of the most difficult challenges in medicine, because it can involve so many different patterns of symptoms, some of which may be mistaken for signs of infectious disease or stroke.[32]

The panel concluded that long-term IS agents during maintenance therapy prolong stable renal function, reduce proteinuria, extend renal survival and minimise the toxicity of GCs. AZA, CYC, MMF and CsA seem to be equivalent regarding efficacy but MMF and AZA have a better safety profile, particularly regarding gonadal toxicity and blood pressure control. We found very low certainty of the evidence for TAC as maintenance therapy, with studies mostly restricted to Asian populations.


Before drinking alcohol, first double-check with your doctor to make sure that it is not forbidden with your medicines. Prednisone, non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen, antidepressants, opioids, warfarin and methotrexate can potentially have more side effects if taken with alcohol. If you do drink alcohol it is very important to drink only in moderation.

Sjogren’s syndrome is a disease that causes dryness in your mouth and eyes. It can also lead to dryness in other places that need moisture, such as your nose, throat and skin. Most people who get Sjogren’s syndrome are older than 40. Nine of 10 are women. Sjogren’s syndrome is sometimes linked to rheumatic problems such as rheumatoid arthritis. In Sjogren’s syndrome, your immune system attacks the glands that make tears and saliva. It may also affect your joints, lungs, kidneys, blood vessels, digestive organs and nerves. The main symptoms are:
Mixed connective tissue disease (MCTD) is a autoimmune disorder that causes overlapping features of three connective tissue disorders: lupus, scleroderma, and polymyositis. MCTD may also have features of rheumatoid arthritis. This condition is most often diagnosed in women in their 20’s and 30’s. Occasionally, children are affected. At this time the cause of this condition is unknown.
All of the energy and material transformations that occur within living cells. It includes material changes undergone by substances during all periods of life (growth, maturity, and senescence) and energy changes (transformations of chemical energy of foodstuffs to mechanical energy or heat). Metabolism involves the two fundamental processes of anabolism and catabolism.
Subacute Cutaneous Lupus can cause skin lesions on any part of the body. These lesions often form red, ring-shaped, scaly patches on the skin. These lesions do not itch and often appear on the chest as well as the upper back and neck; however, they may also be seen on the face and arms. Typically, these lesions occur on areas of the body that are exposed to sunlight or fluorescent lights. Furthermore, it is not uncommon for patients with SCLE to have associated joint disease.
For reasons that doctors still don't understand, the immune system sometimes becomes confused, attacking the body itself, a condition known as autoimmune disease. With lupus,the immune system can attack any organ of the body, including the kidneys and brain, although skin and joints are often most affected, he said. Like many autoimmune diseases, it's more common in women.

Whole foods, especially the kinds high in probiotics, antioxidants and prebiotic fiber, can lower inflammation by increasing “good bacteria” in the gut, which help with absorption and defending against toxins or bad bacteria. High-antioxidant foods also have anti-aging effects even for those without lupus or another immune disorder because they fight free radical damage that degenerates cells and tissues.
ANA screening yields positive results in many connective tissue disorders and other autoimmune diseases, and may occur in normal individuals. Subtypes of antinuclear antibodies include anti-Smith and anti-double stranded DNA (dsDNA) antibodies (which are linked to SLE) and anti-histone antibodies (which are linked to drug-induced lupus). Anti-dsDNA antibodies are highly specific for SLE; they are present in 70% of cases, whereas they appear in only 0.5% of people without SLE.[10] The anti-dsDNA antibody titers also tend to reflect disease activity, although not in all cases.[10] Other ANA that may occur in people with SLE are anti-U1 RNP (which also appears in systemic sclerosis and mixed connective tissue disease), SS-A (or anti-Ro) and SS-B (or anti-La; both of which are more common in Sjögren's syndrome). SS-A and SS-B confer a specific risk for heart conduction block in neonatal lupus.[71]

High-antioxidant foods also have anti-aging effects even for those without lupus or another immune disorder because they fight free radical damage that degenerates cells and tissues.
For some patients whose kidneys or central nervous systems are affected by lupus, a type of drug called an immunosuppressive may be used. Immunosuppressives, such as cyclophosphamide and mycophenolate mofetil, restrain the overactive immune system by blocking the production of immune cells. These drugs may be given by mouth or by IV infusion. The risk for side effects increases with the length of treatment.
A chronic inflammation of large arteries, usually the temporal, occipital, or ophthalmic arteries, identified on pathological specimens by the presence of giant cells. It causes thickening of the intima, with narrowing and eventual occlusion of the lumen. It typically occurs after age 50. Symptoms include headache, tenderness over the affected artery, loss of vision, and facial pain. The cause is unknown, but there may be a genetic predisposition in some families. Corticosteroids are usually administered.
An antinuclear antibody (ANA) test is a sensitive screening tool used to detect autoimmune diseases, including lupus. Antinuclear antibodies (ANAs) are antibodies that are directed against certain structures within a cell's nucleus (thus, antinuclear antibody). ANAs are found in particular patterns in people with autoimmune diseases (those in which a person's immune system works against his or her own body).
Kaposi observed that lupus assumed two forms: the skin lesions (now known as discoid lupus) and a more aggravated form that affected not only the skin but also caused fever, arthritis, and other systemic disorders in people.[112] The latter also presented a rash confined to the face, appearing on the cheeks and across the bridge of the nose; he called this the "butterfly rash". Kaposi also observed those patients who developed the "butterfly rash" (or malar rash) often were afflicted with another disease such as tuberculosis, anemia, or chlorisis which often caused death.[110] Kaposi was one of the first people to recognize what is now termed systemic lupus erythematosus in his documentation of the remitting and relapsing nature of the disease and the relationship of skin and systemic manifestations during disease activity.[113]
Hormonal mechanisms could explain the increased incidence of SLE in females. The onset of SLE could be attributed to the elevated hydroxylation of estrogen and the abnormally decreased levels of androgens in females. In addition, differences in GnRH signalling have also shown to contribute to the onset of SLE. While females are more likely to relapse than males, the intensity of these relapses is the same for both sexes.[12]

Systemic lupus erythematosus (SLE) is a complex multisystemic autoimmune disease resulting, oftentimes, in irreversible damage, diminished quality of life and reduced life expectancy.1–3 Genetic and environmental factors play important roles in its pathogenesis.4–8 Disease manifestations and severity vary according to the patients’ racial/ethnic background and socioeconomic status (SES).1 9 10 Data from Grupo Latino Americano de Estudio del Lupus (GLADEL), Lupus in Minorities: Nature vs Nurture (LUMINA) and the Lupus Family Registry and Repository cohorts have demonstrated that Latin American and North American Mestizo patients (mixed Amerindian and European ancestry), African descendants and Native Americans develop lupus earlier11 12 although diagnostic delays may occur.1 They also experience more severe disease, have higher disease activity levels,1 accrue more organ damage2 and have higher mortality rates,1 succumbing mainly to disease activity and/or infections.1 3 13–15


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.​​
Opportunistic infections can develop, most often in patients receiving chronic immunosuppressive therapy. Another less-common complication is osteonecrosis, especially of the hips and knees after prolonged high-dose corticosteroid usage. More commonly, premature atherosclerotic disease and myocardial infarction are indolent complications of chronic inflammation and steroids.
Blood and urine tests. The antinuclear antibody (ANA) test can show if your immune system is more likely to make the autoantibodies of lupus. Most people with lupus test positive for ANA. But, a positive ANA does not always mean you have lupus. If you test positive for ANA, your doctor will likely order more tests for antibodies that are specific to systemic lupus erythematosus (SLE).
(C) Positive finding of antiphospholipid antibodies based on (1) an abnormal serum level of IgG or IgM anticardiolipin antibodies, (2) a positive test result for lupus anticoagulant using a standard method, or (3) a false-positive serologic test for syphilis known to be positive for =6 months and confirmed by Treponema pallidum immobilization or fluorescent treponemal antibody absorption tests

According to the Lupus Foundation of America, approximately 1.5 million people in the U.S. have lupus. People of African, Asian, and Native American descent are more likely to develop lupus than are Caucasians. Although it can occur in both men and women, 90% of people diagnosed with the disease are women. Women of childbearing age (14 to 45 years old) are most often affected and as many as 1 in 250 people may develop lupus.
Flare-ups of lupus can cause acute inflammation and damage to various body tissues and can affect the joints, skin, kidneys, heart, lungs, blood vessels, and brain. Some of the most common symptoms are painful or swollen joints, unexplained fever, kidney problems and extreme fatigue. A characteristic red skin rash – called a “malar” or “butterfly” rash because it roughly mimics the insect’s shape – may appear across the nose and cheeks. Rashes may also occur on the face and ears, upper arms, shoulders, chest, and hands. Because many lupus patients are sensitive to sunlight, skin rashes often develop or worsen after sun exposure.
In the United States, systemic lupus erythematosus is reported to be more common in women, particularly black women, than in white men.14,16 One U.S. retrospective study16 of medical records found that the disease is diagnosed 23 times more often in black women than in white men. The prevalence of the disease is also higher in Hispanic and Asian Americans.16 In addition, a familial predisposition to systemic lupus erythematosus has been identified.17-19
People with lupus should know that most rashes, and sometimes other symptoms, are aggravated by sun exposure, so you’ll want to avoid it or use sun protection. It’s critical to talk to your doctor about skin rashes and lesions that you observe, as many are treated differently, and some can be signs that the disease is progressing or changing. You may need other treatments, too.
It also is known that some women with systemic lupus erythematosus can experience worsening of their symptoms prior to their menstrual periods. This phenomenon, together with the female predominance of systemic lupus erythematosus, suggests that female hormones play an important role in the expression of SLE. This hormonal relationship is an active area of ongoing study by scientists.
Nutrients that are important for managing lupus, such as fiber and antioxidants, seem to have the most beneficial effects when consumed from real food rather than from supplements.  What type of foods are included in a lupus diet? These include healthy fats, plenty of fresh veggies and fruits, and probiotic foods. Considering the fact that lupus can increase your risk for other chronic health problems (for example, women with lupus have a five- to tenfold higher risk for heart disease than the general population!), a nutrient-rich lupus diet can have far-reaching protective effects.

The most serious health risks are cardiovascular disease, kidney disease and stroke. Specifically, people with lupus are at increased risk for atherosclerosis (hardening of the arteries). In some people, inflammation can occur in the heart itself (myocarditis and endocarditis) or the membrane that surrounds it. Endocarditis can damage heart valves, which can result in heart murmurs. When the disease affects the kidneys, patients generally require intensive drug treatment to prevent permanent damage. Lupus also may attack the brain or central nervous system, which can cause seizures or stroke.
Certain foods, including garlic and alfalfa sprouts, should be avoided by people with lupus. [For a more complete list of items to be avoided, please see the article “Things to Avoided” in the Lupus 101 section.] Recently controversy has also arisen over whether aspartame induces lupus. However, scientists have concluded that there is no evidence to suggest that aspartame causes lupus.

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.
If your doctor suspects you have lupus based on your symptoms, a series of blood tests will be done in order to confirm the diagnosis. The most important blood screening test is ANA. If ANA is negative, you don’t have lupus. However, if ANA is positive, you might have lupus and will need more specific tests. These blood tests include antibodies to anti-dsDNA and anti-Sm, which are specific to the diagnosis of lupus.
