This gene encodes a member of the interferon regulatory factor (IRF) family, a group of transcription factors with diverse roles, including virus-mediated activation of interferon, and modulation of cell growth, differentiation, apoptosis, and immune system activity. Members of the IRF family are characterized by a conserved N-terminal DNA-binding domain containing tryptophan (W) repeats. Alternative promoter use and alternative splicing result in multiple transcript variants, and a 30-nt indel polymorphism (SNP rs60344245) can result in loss of a 10-aa segment.
Symptoms vary from person to person, but the typical lupus patient is a young woman experiencing fever, swollen lymph nodes (glands), butterfly-shaped rash on her face, arthritis of the fingers, wrists or other small joints, hair loss, chest pain and protein in the urine. Symptoms usually begin in only one or two areas of the body, but more may develop over time. The most common signs and symptoms of lupus are:
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.
While there’s no one dietary program that can cure or treat lupus for all patients, a healthy lupus diet can go a long way in preventing flare-ups and decreasing complications. Molly’s Fund for Fighting Lupus states that a healthy diet is needed to prevent nutrient deficiencies, maintain strength and energy, combat medication side effects, maintain a healthy weight, and protect the heart. (4)

Corticosteroids, such as prednisone, hydrocortisone, methylprednisolone, and dexamethasone, are related to cortisol, which is a natural anti-inflammatory hormone. They work by rapidly suppressing inflammation. Corticosteroids can be given by mouth, in creams applied to the skin, by injection, or by intravenous (IV) infusion (dripping the drug into the vein through a small tube). Because they are potent drugs, the doctor will seek the lowest dose required to achieve the desired benefit.


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.
The GRADE approach was followed in the process (http://www.gradeworkinggroup.org) 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.
The global rates of SLE are approximately 20–70 per 100,000 people. In females, the rate is highest between 45 and 64 years of age. The lowest overall rate exists in Iceland and Japan. The highest rates exist in the US and France. However, there is not sufficient evidence to conclude why SLE is less common in some countries compared to others; it could be the environmental variability in these countries. For example, different countries receive different levels of sunlight, and exposure to UV rays affects dermatological symptoms of SLE. Certain studies hypothesize that a genetic connection exists between race and lupus which affects disease prevalence. If this is true, the racial composition of countries affects disease, and will cause the incidence in a country to change as the racial makeup changes. In order to understand if this is true, countries with largely homogenous and racially stable populations should be studied to better understand incidence.[2] Rates of disease in the developing world are unclear.[6]
At least half of people with lupus experience fatigue. (4) Fatigue may be brought on by the disease itself or from associated depression, anxiety, lack of exercise, and problems with sleep. ( 5) Because people with lupus need to avoid sun exposure, they may have low levels of vitamin D, which can contribute to fatigue. Lupus treatments may also play a role.

One food to avoid is alfalfa sprouts. Alfalfa tablets have been associated with lupus flares or a lupus-like syndrome that includes muscle pain, fatigue, abnormal blood test results, and kidney problems. These problems may be due to a reaction to an amino acid found in alfalfa sprouts and seeds. This amino acid can activate the immune system and increase inflammation in people with lupus. Garlic may also stimulate the immune system.
Autoreactive B cells can accidentally emerge during somatic hypermutation and migrate into the germinal center light zone. Autoreactive B cells, maturated coincidentally, normally do not receive survival signals by antigen planted on follicular dendritic cells and perish by apoptosis. In the case of clearance deficiency, apoptotic nuclear debris accumulates in the light zone of GC and gets attached to FDC. This serves as a germinal centre survival signal for autoreactive B-cells. After migration into the mantle zone, autoreactive B cells require further survival signals from autoreactive helper T cells, which promote the maturation of autoantibody-producing plasma cells and B memory cells. In the presence of autoreactive T cells, a chronic autoimmune disease may be the consequence.

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.


While acute pain is a normal sensation triggered in the nervous system to alert you to possible injury and the need to take care of yourself, chronic pain is different. Chronic pain persists. Pain signals keep firing in the nervous system for weeks, months, even years. There may have been an initial mishap — sprained back, serious infection, or there may be an ongoing cause of pain — arthritis, cancer, ear infection, but some people suffer chronic pain in the absence of any past injury or evidence of body damage. Many chronic pain conditions affect older adults. Common chronic pain complaints include headache, low back pain, cancer pain, arthritis pain, neurogenic pain (pain resulting from damage to the peripheral nerves or to the central nervous system itself), psychogenic pain (pain not due to past disease or injury or any visible sign of damage inside or outside the nervous system). A person may have two or more co-existing chronic pain conditions. Such conditions can include chronic fatigue syndrome, endometriosis, fibromyalgia, inflammatory bowel disease, interstitial cystitis, temporomandibular joint dysfunction, and vulvodynia. It is not known whether these disorders share a common cause.

The goal of the informed consent process is to protect participants. It begins when a potential participant first asks for information about a study and continues throughout the study until the study ends. The researcher and potential participant have discussions that include answering the participant’s questions about the research. All the important information about the study must also be given to the potential participant in a written document that is clear and easy to understand. This informed consent document is reviewed and approved by the human subjects review board for a study before it is given to potential participants. Generally, a person must sign an informed consent document to enroll in a study.

Once a lupus diagnosis has been confirmed by your physician, you will have many questions.  Here is a quick list of questions to help you get started in getting the necessary information in order to have a better understanding of your specific symptoms and move forward towards the most successful course of treatment and/or management of the disease. It may also be helpful to have an advocate along with you like a friend or loved one to help you remember important details:
Regulatory T cells (Tregs) are a population of CD4+ T cells with a unique role in the immune response. Tregs are crucial in suppressing aberrant pathological immune responses in autoimmune diseases, transplantation, and graft-vs-host disease after allogeneic hematopoietic stem cell transplantation. Tregs are activated through the specific T-cell receptor, but their effector function is nonspecific and they regulate the local inflammatory response through cell-to-cell contact and cytokine secretion. Tregs secrete interleukin (IL)-9 (IL-9), IL-10, and transforming growth factor-beta 1 (TGF-beta 1), which aid in the mediation of immunosuppressive activity.
If you have difficulty with certain tasks in the kitchen due to stiffness, pain or weakness, there is a wide range of special equipment available that can make things easier. You can find details about many of these products for homes and kitchens HERE. You may wish to discuss the possibility of being referred to your rheumatology clinic’s occupational therapy team so that you can have your individual needs assessed.

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.
The erythrocyte sedimentation rate (ESR) test is a blood test that measures inflammation in your body and is used to help diagnose conditions associated with acute and chronic inflammation, including lupus. It is usually used in conjunction with other tests, as the test itself is nonspecific. In other words, it can detect increases in inflammation, but it doesn't pinpoint where the inflammation is or point to a specific disease. Other conditions can affect outcomes of the test as well. The test is one that is usually conducted several times over a certain period to measure changes in inflammation.
Medical historians have theorized that people with porphyria (a disease that shares many symptoms with SLE) generated folklore stories of vampires and werewolves, due to the photosensitivity, scarring, hair growth, and porphyrin brownish-red stained teeth in severe recessive forms of porphyria (or combinations of the disorder, known as dual, homozygous, or compound heterozygous porphyrias).[121]

Inflammation of blood vessels (vasculitis) that supply oxygen to tissues can cause isolated injury to a nerve, the skin, or an internal organ. The blood vessels are composed of arteries that pass oxygen-rich blood to the tissues of the body and veins that return oxygen-depleted blood from the tissues to the lungs. Vasculitis is characterized by inflammation with damage to the walls of various blood vessels. The damage blocks the circulation of blood through the vessels and can cause injury to the tissues that are supplied with oxygen by these vessels.


ANAs are proteins made by the body that can attach to DNA and other substances inside cells. But just because they are present in the body doesn’t necessarily mean they will attack these substances. These antibodies are found in at least 5% of the general population, so there are "many more people walking around with ANAs who are perfectly healthy or have some illness that has nothing to do with lupus," adds Dr. Belmont.
If this disorder is suspected in people, brain scans are usually required for early detection. These scans can show localized areas of the brain where blood supply has not been adequate. The treatment plan for these people requires anticoagulation. Often, low-dose aspirin is prescribed for this purpose, although for cases involving thrombosis anticoagulants such as warfarin are used.[91]
  According to the Mayo Clinic, “People with lupus should eat plenty of fruits, vegetables and whole grains. These foods are rich in vitamins, minerals and essential nutrients that benefit overall health and can help prevent high blood pressure, heart disease, kidney disease, cancer and digestive disorders. Plant-based diets also support a healthy weight because they are naturally low in calories, fat and cholesterol. Fruits and vegetables are particularly high in antioxidants. Antioxidants protect the body by destroying harmful substances that damage cells and tissue and cause heart disease and cancer.” Take a look at our blog, Lupus: the Diet Dilemma for some great tips. While these diets, or eating plans, may have some merit, individual foods should not be the focus. Pay attention to your overall pattern of nutrition. Reducing inflammation is not just about what you eat.  Patients should also know that these diets are never meant to be a replacement for the lupus treatments they may already be taking under the close supervision of a medical professional. Until more research is in on the effectiveness of these diets, be practical by getting enough sleep and exercise, and try to maintain a healthy weight. Back to top
According to Goldman Foung, “A diet rich in vegetables gives me energy and keeps me feeling strong and healthy." She typically eats meals filled with dark leafy greens and other colorful vegetables, eats lots of whole grains, and limits her consumption of meat and processed foods. “I also try to drink fresh-pressed beet juice as often as possible,” she adds. “It’s a great way to sneak in some of those body-boosting ingredients.”
Systemic sclerosis (SSc): Similar symptoms between SSc and lupus are reflux and Raynaud's disease (when your fingers turn blue or white with cold). One difference between SSc and lupus is that anti-double-stranded DNA (dsDNA) and anti-Smith (Sm) antibodies, which are linked to lupus, don't usually occur in SSc. Another differentiator is that people with SSc often have antibodies to an antigen called Scl-70 (topoisomerase I) or antibodies to centromere proteins.

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 https://doi.org/10.5061/dryad.bg8452h.

Vasculitis, antiphospholipid antibodies, and renal failure are commonly found in patients with lupus; these conditions greatly increase the risk of developing pulmonary emboli. The diagnosis in a patient with shortness of breath, hemoptysis, and pleuritic chest pain is commonly made with ventilation-perfusion scans or computed tomography (CT) angiography. The CT angiogram demonstrates a filling defect in the left anterior segmental artery (arrow).
The panel concluded that both MMF plus high-dose GCs (prednisone 1–2 mg/kg/day, maximum 60 mg/day) and CYC plus high-dose GCs are associated with significant benefits in comparison to GCs alone. No significant differences between these two alternatives were noted. The panel pointed that differential pharmacokinetic effects of MMF in cLN may exist, which could require dosing increase.30 Risk of reduction of ovarian reserve and sperm abnormalities should be considered in patients with cLN treated with CYC.

Steroid medications such as prednisone can also cause significant weight gain and redistribution of fat stores in the body. While taking steroids, your cholesterol, triglyceride, and blood sugar (glucose) levels may increase. For these reasons, it is absolutely essential that you follow a low-fat, low-cholesterol diet. You do not need to cut out all of the foods you love, but concentrate on eating whole grain breads and cereals and lean sources of protein such as chicken and fish. When you need a snack, look to raw vegetables—they are low in sugar and calories and provide the perfect food for “grazing.” Try to eat them without Ranch dressing or vegetable dip, because these items carry lots of fat and calories. If you need something to accompany your vegetables, try lighter dips like hummus. It is also important that you minimize alcohol intake ,because combining alcohol with corticosteroids, Tylenol, warfarin, and other lupus medications could be very harmful to your liver and stomach. For those taking methotrexate, alcohol is never allowed.
It is important to understand that osteoporosis has no symptoms. There is no pain in the bones where individuals with osteoporosis would hypothetically feel sore, so it is important to speak with your doctor to have a regular bone mass density test performed. Again, there is a high risk of osteoporosis for people with lupus because of often decreased physical activity, vitamin D deficiency, medication side effects, and the additional risk of kidney disease. Listed below are nutritional tips to follow:
On my first (and last) visit to the rheumatologist I asked what I could do to support my health or to avoid a worsening my lupus symptoms. She casually responded "Come back when you're worse and I'll put you on steroids". Straining to get some kind of supportive information I mustered up a question about diet and if there were foods I should eat or avoid. Her response was, "continue to eat whatever you want, it won't make a difference".
ANA = antinuclear antibody; CNS = central nervous system; ds-DNA = double-stranded DNA; ELISA = enzyme-linked immunoassay; ENA = extractable nuclear antigen; Ig = immunoglobulin; p-ANCA = perinuclear antineutrophil cytoplasmic antibody; RBCs = red blood cells; RNP = ribonucleic protein; SLE = systemic lupus erythematosus; Sm = Smith; SSA = Sjögren syndrome A; SSB = Sjögren syndrome B.

B cells are essential for the development and pathogenesis of both systemic and organ-specific autoimmune diseases. Autoreactive B cells are typically thought of as sources of autoantibody, but their most important pathogenetic roles may be to present autoantigens to T cells and to secrete proinflammatory cytokines. A rate-limiting step in the genesis of autoimmunity then is the activation of autoreactive B cells. Here, mechanisms are discussed that normally prevent such activation and how they break down during disease. Integrating classic work with recent insights, emphasis is placed on efforts to pinpoint the precursor cells for autoantibody-secreting cells and the unique stimuli and pathways by which they are activated.


Medical historians have theorized that people with porphyria (a disease that shares many symptoms with SLE) generated folklore stories of vampires and werewolves, due to the photosensitivity, scarring, hair growth, and porphyrin brownish-red stained teeth in severe recessive forms of porphyria (or combinations of the disorder, known as dual, homozygous, or compound heterozygous porphyrias).[121]
Because the antibodies and accompanying cells of inflammation can affect tissues anywhere in the body, lupus has the potential to affect a variety of areas. Sometimes lupus can cause disease of the skin, heart, lungs, kidneys, joints, and/or nervous system. When only the skin is involved by rash, the condition is called lupus dermatitis or cutaneous lupus erythematosus. A form of lupus dermatitis that can be isolated to the skin, without internal disease, is called discoid lupus erythematosus. When internal organs are involved, the condition is referred to as systemic lupus erythematosus (SLE).
Some people find that excluding gluten from their diet gives them more energy. Don’t be tempted to start excluding a lot of foods from your diet; this could lead to serious deficiencies. Avoiding gluten or dairy products will not necessarily prevent flares; food “triggers” vary greatly from person to person.  If you feel that you have problems processing certain foods, talk to your GP and ask for a referral to either a dietician or an allergy specialist within the NHS. There are commercial allergy tests available, but these are not always accurate and could cost you a lot of money but bring you no lasting benefit.
Most autoimmune diseases affect one specific system. For example, Rheumatoid Arthritis involves the joints, and Multiple Sclerosis affects the brain and spinal cord. Lupus, on the other hand, affects more than one system simultaneously. No matter what organ or system is being attacked, all autoimmune diseases are similar in that they are an immune response caused by systemic inflammation that leads your body to attack itself.
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).
Belimumab, a type of agent referred to as a B-lymphocyte stimulator (BLyS) protein inhibitor, was approved by the U.S. Food and Drug Administration (FDA) in March 2011 for patients with lupus who are receiving other standard therapies, including those listed above. Given by IV infusion, belimumab may reduce the number of abnormal B cells thought to be a problem in lupus.
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]
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.
What are the causes and types of arthritis? Arthritis is a term that describes around 200 conditions that cause pain in the joints and the tissues surrounding the joints. The most common form of arthritis is osteoarthritis. Other related conditions include gout and fibromyalgia. The article looks at the types, causes, and treatments, including natural remedies.
