A specialized type of dense connective tissue consisting of cells embedded in a ground substance or matrix. The matrix is firm and compact; its proteoglycans can store considerably more sodium than plasma can, which in turn allows cartilage to store water, which in turn helps cartilage withstand pressure or impact. Cartilage is bluish-white or gray and is semiopaque; it has no nerve or blood supply of its own. The cells lie in cavities called lacunae. They may be single or in groups of two, three, or four. Cartilage forms parts of joints in the adult skeleton, such as between vertebral bodies and on the articular surfaces of bones. It also occurs in the costal cartilages of the ribs, in the nasal septum, in the external ear and lining of the eustachian tube, in the wall of the larynx, and in the trachea and bronchi. It forms the major portion of the embryonic skeleton, providing a model in which most bones develop.
Acute Cutaneous Lupus results in flat red patches on the cheeks and nose called a malar or butterfly rash that looks quite like sunburn. These patches may also appear on the arms, legs, trunk and any other area that is commonly exposed to the sun. Patients with Acute Cutaneous Lupus can also manifest oral ulcers, hives and temporary hair loss. Acute Cutaneous Lupus is more common in people living with SLE.
Levels of stress-related illnesses are on the rise, and stress, both emotional and physical, has been shown to trigger and intensify autoimmune disorders. Stress is your body’s response to a threat–a wound, injury, or infection. Acute stress revs up your immune system to help you deal with an immediate crisis, and then calms it back down once the threat is removed. On the other hand, chronic stress (the kind we face in this day and age) leads to long-term inflammation and actually suppresses your immune system. This can trigger or worsen autoimmune conditions, and can lead to the reactivation of latent viruses linked to lupus, perpetuating a vicious cycle.
An inflammatory response (inflammation) occurs when tissues are injured by bacteria, trauma, toxins, heat, or any other cause. The damaged cells release chemicals including histamine, bradykinin, and prostaglandins. These chemicals cause blood vessels to leak fluid into the tissues, causing swelling. This helps isolate the foreign substance from further contact with body tissues.
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.
Lupus is an inflammatory autoimmune disease that can affect multiple parts of the body including the various organ systems. Doctors prescribe traditional pharmaceutical medications to manage symptoms and prevent flare ups of the disease that can cause more serious problems and complications. Many patients choose to supplement their pharmaceutical care with alternative treatments and lifestyle adjustments like using diet and exercise to minimize lupus symptoms. We discuss this further in our blog, Lupus/Chronic Illness: The Mind/Body Connection. There exists two major diets widely discussed in the autoimmune world. One is the anti-inflammatory diet and one is called the Paleo Diet.
Your primary care doctor should coordinate care between your different health care providers and treat other problems as they come up. Your doctor will develop a treatment plan to fit your needs. You and your doctor should review the plan often to be sure it is working. You should report new symptoms to your doctor right away so that your treatment plan can be changed if needed.
In general, cutaneous manifestations, musculoskeletal manifestations, and serositis represent milder disease, which may wax and wane with disease activity. These are often controlled with nonsteroidal anti-inflammatory drugs (NSAIDS) or low-potency immunosuppression medications beyond hydroxychloroquine and/or short courses of corticosteroids. More prolonged steroid use is generally reserved for patients with involvement of vital organs. For example, central nervous system involvement and diffuse proliferative renal disease must be recognized as more severe disease manifestations, and these are often treated with more aggressive immunosuppression. Evidence suggests a relative undertreatment of SLE patients with end-stage renal disease (ESRD), because the extent of lupus activity may be underestimated. 
It is estimated that more than 1.5 million Americans have lupus. African American women are three times more likely than white women to have it. Hispanic, Asian and Native American women also have a higher incidence of lupus. People of all ages, races and sexes can get lupus, but 9 out of 10 adults with the disease are women between the ages of 15 and 45.
Blood clots are seen with increased frequency in lupus. Clots often occur in the legs (a vein clot, called deep venous thrombosis), lungs (a lung clot, called pulmonary embolus), or brain (stroke). Blood clots that develop in lupus patients may be associated with the production of antiphospholipid antibodies. These antibodies are abnormal proteins that may increase the tendency of the blood to clot.
The monoclonal antibody belimumab (Benlysta), a B-lymphocyte stimulator–specific inhibitor, has been found to reduce disease activity and possibly decrease the number of severe flares and steroid use in patients with SLE when used in combination with standard therapy.  In March, 2011, the US Food and Drug Administration (FDA) approved the use of belimumab in combination with standard therapies (including steroids, nonbiologic DMARDS [eg, hydroxychloroquine, azathioprine, methotrexate]) to treat active autoantibody-positive SLE.  In July 2017, a subcutaneous (SC) formulation was approved that allows patients to self-administer a once-weekly dose. 
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.
Avoiding sunlight in SLE is critical, since sunlight is known to exacerbate skin manifestations of the disease. Avoiding activities which induce fatigue is also important, since those with SLE fatigue easily and it can debilitating. These two problems can lead to people becoming housebound for long periods of time. Drugs unrelated to SLE should be prescribed only when known not to exacerbate the disease. Occupational exposure to silica, pesticides, and mercury can also worsen the disease.
In more severe cases, medications that modulate the immune system (primarily corticosteroids and immunosuppressants) are used to control the disease and prevent recurrence of symptoms (known as flares). Depending on the dosage, people who require steroids may develop Cushing's syndrome, symptoms of which may include obesity, puffy round face, diabetes mellitus, increased appetite, difficulty sleeping and osteoporosis. These may subside if and when the large initial dosage is reduced, but long-term use of even low doses can cause elevated blood pressure and cataracts.

Drug-induced lupus erythematosus is a (generally) reversible condition that usually occurs in people being treated for a long-term illness. Drug-induced lupus mimics SLE. However, symptoms of drug-induced lupus generally disappear once the medication that triggered the episode is stopped. More than 38 medications can cause this condition, the most common of which are procainamide, isoniazid, hydralazine, quinidine, and phenytoin.
This axial, T2-weighted brain magnetic resonance image (MRI) demonstrates an area of ischemia in the right periventricular white matter of a 41-year-old woman with long-standing systemic lupus erythematosus (SLE). She presented with headache and subtle cognitive impairments but no motor deficits. Faintly increased signal intensity was also seen on T1-weighted images, with a trace of enhancement following gadolinium that is too subtle to show on reproduced images. Distribution of the abnormality is consistent with occlusion of deep penetrating branches, such as may result from local vasculopathy, with no clinical or laboratory evidence of lupus anticoagulant or anticardiolipin antibody. Cardiac embolus from covert Libman-Sacks endocarditis remains less likely due to distribution.

Sometimes, changes in blood counts (low red cell count, or anemia), may cause fatigue, serious infections (low white cell count), or easy bruising or bleeding (low platelet count). Many patients do not have symptoms from low blood counts, however, so it is important for people with lupus to have periodic blood tests in order to detect any problems.
Based on the identified evidence the panel concluded that compared with GCs alone, the addition of other IS (CYC, MMF or TAC) is associated with significant benefits, higher remission rates and lower progression rates to end-stage renal disease (ESRD). Head-to-head comparisons between MMF, TAC and high-dose CYC showed that MMF and TAC are associated with less adverse effects than high-dose CYC. Between low and high-dose CYC the balance favours the former because of better safety profile and comparable efficacy, although this conclusion is based on one trial that included predominantly Caucasians. RTX did not provide additional benefits when combined with MMF.
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. Other genes which contain risk variants for SLE are IRF5, PTPN22, STAT4, CDKN1A, ITGAM, BLK, TNFSF4 and BANK1. Some of the susceptibility genes may be population specific.
Your kidneys are two bean-shaped organs, each about the size of your fists. They are located near the middle of your back, just below the rib cage. Inside each kidney about a million tiny structures called nephrons filter blood. They remove waste products and extra water, which become urine. The urine flows through tubes called ureters to your bladder, which stores the urine until you go to the bathroom. Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines.
There’s no scientific evidence that avoiding red meat will have an effect on lupus. If you have kidney disease, red meat can give you more protein than your kidneys can handle. If you have high cholesterol or high triglyceride levels, red meat can raise these further. On the other hand, if you have inflammation in your body you need more protein than when you’re healthy. So the bottom line is to eat a well-balanced diet. If you’re not sure how much you should be eating, ask your doctor to refer you to a Registered Dietitian for a consultation.
While the genetics of SLE are not very well understood, there is growing evidence for the involvement of specific genes in this complex autoimmune disease. Part of the complexity of this disease is due to the effects of both environment and genetics factors that may contribute to its development. Further compounding our understanding of the etiology of the disease is the involvement of several organ systems. Genetic studies of the rates of disease in families supports the genetic basis of this disease with a heritability of >66%. Identical (monozygotic) twins were found to share susceptibility to the disease at >35% rate compared to fraternal (dizygotic) twins and other full siblings who only showed a 2–5% concordance in shared inheritance.
How an autoimmune disease affects you depends on what part of the body is targeted. If the disease affects the joints, as in rheumatoid arthritis, you might have joint pain, stiffness, and loss of function. If it affects the thyroid, as in Graves’ disease and thyroiditis, it might cause tiredness, weight gain, and muscle aches. If it attacks the skin, as it does in scleroderma/systemic sclerosis, vitiligo, and systemic lupus erythematosus (SLE), it can cause rashes, blisters, and color changes.
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.
Dozens of medications have been reported to trigger SLE. However, more than 90% of cases of "drug-induced lupus" occurs as a side effect of one of the following six drugs: hydralazine (Apresoline) is used for high blood pressure; quinidine (Quinidine Gluconate, Quinidine Sulfate) and procainamide (Pronestyl; Procan-SR; Procanbid) are used for abnormal heart rhythms; phenytoin (Dilantin) is used for epilepsy; isoniazid (Nydrazid, Laniazid) is used for tuberculosis; and d-penicillamine (used for rheumatoid arthritis
Describes a clinical study in which groups of participants receive one of several combinations of interventions. For example, a two-by-two factorial design involves four groups of participants. Each group receives one of the following pairs of interventions: 1) drug A and drug B, 2) drug A and a placebo, 3) a placebo and drug B, or 4) a placebo and a placebo. So during the trial, all possible combinations of the two drugs (A and B) and placebos are given to different groups of participants.
The symptoms involved in CREST syndrome are associated with the generalized form of the disease Systemic sclerosis (scleroderma). CREST is an acronym for the clinical features that are seen in a patient with this disease. The “C” stands for calcinosis, where calcium deposits form under the skin on the fingers or other areas of the body. The “R”, stands for Raynaud’s phenomenon, spasm of blood vessels in the fingers or toes in response to cold or stress. The “E” represents esophageal dysmotility, which can cause difficulty in swallowing. The “S” is for sclerodactyly, tightening of the skin causing the fingers to bend. Finally, the letter “T” is for telangiectasia, dilated vessels on the skin of the fingers, face, or inside of the mouth.
The CBC is among the most common blood tests performed in the clinical laboratory and aids in the diagnosis of anemia and erythrocytosis; bleeding and the repletion of blood cells by transfusion, thrombocytopenia and thrombocytosis; and infections and leukemias. Blood is obtained for the test from venipuncture or aspiration from an indwelling vascular access or port. It is taken to the laboratory in a tube that contains the anticoagulant ethylenediaminetetraacetic acid (EDTA).
Intravenous immunoglobulins may be used to control SLE with organ involvement, or vasculitis. It is believed that they reduce antibody production or promote the clearance of immune complexes from the body, even though their mechanism of action is not well understood. Unlike immunosuppressives and corticosteroids, IVIGs do not suppress the immune system, so there is less risk of serious infections with these drugs.
Doctors are tasked with interpreting test results, then correlating them with your symptoms and other test results. It's difficult when patients exhibit vague symptoms and clashing test results, but skillful doctors can consider all of these pieces of evidence and eventually determine whether you have lupus or something else entirely. This may take some time along with trial and error.
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.
Gene regulation is the process of turning genes on and off. During early development, cells begin to take on specific functions. Gene regulation ensures that the appropriate genes are expressed at the proper times. Gene regulation can also help an organism respond to its environment. Gene regulation is accomplished by a variety of mechanisms including chemically modifying genes and using regulatory proteins to turn genes on or off.
Inflammation of the kidneys caused by an autoimmune disease called systemic lupus erythematosus. The condition can cause hematuria and proteinuria, and it may progress to end-stage renal disease. The most severe form of lupus nephritis, called diffuse proliferative nephritis, can cause scars to form in the kidneys. Scars are permanent, and kidney function often declines as more scars form. Early diagnosis and treatment may help prevent long-lasting damage.
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).
I recommend having your MTHFR genes tested, as this genetic mutation can impact how you detoxify mercury and other heavy metals. There are multiple options for heavy metal testing, however I’ve found the DMPS “challenge” test to be the gold standard. To assess whether someone is being exposed to mycotoxins, I use the test from Real Time Lab. If either heavy metals or mycotoxins are an issue for you, work on minimizing your exposure to these toxins, and be sure to support your detox pathways while you work to flush them out.
Not all fats are unhealthy. Polyunsaturated fats and monounsaturated fats are the healthier fats compared to saturated fats. Some of these fats are high in anti-inflammatory properties and have a rich source of Vitamin E. Foods that contain unsaturated fats include; nuts, seeds, avocados, olive oil, soybean oil, and canola oil. It is important to understand that these fats are still high in calories - therefore, portions should be monitored. These fats, however, are preferred over saturated fats.
Research indicates that omega 3 fatty acids from fish or fish oils may help manage high triglycerides and heart disease (see references at end of this summary). There have not been any studies, however, that show a reduced disease activity with lupus. Foods rich in omega 3 fatty acids include salmon, sardines, mackerel, bluefish, herring, mullet, tuna, halibut, lake trout, rainbow trout, ground flaxseed, walnuts, pecans, canola oil, walnut oil, and flaxseed oil, and are part of a heart-healthy meal plan.
Conventional lupus treatment usually involves a combination of medications used to control symptoms, along with lifestyle changes — like dietary improvements and appropriate exercise. It’s not uncommon for lupus patients to be prescribed numerous daily medications, including corticosteroid drugs, NSAID pain relievers, thyroid medications and even synthetic hormone replacement drugs. Even when taking these drugs, it’s still considered essential to eat an anti-inflammatory lupus diet in order to manage the root causes of lupus, along with reducing its symptoms.
While SLE can occur in both males and females, it is found far more often in women, and the symptoms associated with each sex are different. Females tend to have a greater number of relapses, a low white blood cell count, more arthritis, Raynaud's phenomenon, and psychiatric symptoms. Males tend to have more seizures, kidney disease, serositis (inflammation of tissues lining the lungs and heart), skin problems, and peripheral neuropathy.
The immune system must balance between being sensitive enough to protect against infection, and become sensitized to attack the body's own proteins (autoimmunity). During an immune reaction to a foreign stimulus, such as bacteria, virus, or allergen, immune cells that would normally be deactivated due to their affinity for self-tissues can be abnormally activated by signaling sequences of antigen-presenting cells. Thus triggers may include viruses, bacteria, allergens (IgE and other hypersensitivity), and can be aggravated by environmental stimulants such as ultraviolet light and certain drug reactions. These stimuli begin a reaction that leads to destruction of other cells in the body and exposure of their DNA, histones, and other proteins, particularly parts of the cell nucleus. The body's sensitized B-lymphocyte cells will now produce antibodies against these nuclear-related proteins. These antibodies clump into antibody-protein complexes which stick to surfaces and damage blood vessels in critical areas of the body, such as the glomeruli of the kidney; these antibody attacks are the cause of SLE. Researchers are now identifying the individual genes, the proteins they produce, and their role in the immune system. Each protein is a link on the autoimmune chain, and researchers are trying to find drugs to break each of those links.
Drug-induced lupus erythematosus (DIL) Some drugs can cause lupus, resulting in symptoms such as rash, arthritis, hair loss, and fever. “Once medications are discontinued, the symptoms go away,” says Roberto Caricchio, MD, the interim section chief of rheumatology at Temple University Hospital in Philadelphia and the director of the Temple Lupus Clinic at the Lewis Katz School of Medicine.
EULAR recommendations for the management of SLE with neuropsychiatric manifestations support the evaluation and treatment of these symptoms in the same way as they are evaluated and treated in patients without SLE; if symptoms persist, management of these symptoms as an extension of SLE should be considered. [83, 61] For example, in patients with neuropsychiatric manifestations that may have an inflammatory etiology, immunosuppressive agents may be considered. 
Approximately 20% of people with SLE have clinically significant levels of antiphospholipid antibodies, which are associated with antiphospholipid syndrome. Antiphospholipid syndrome is also related to the onset of neural lupus symptoms in the brain. In this form of the disease the cause is very different from lupus: thromboses (blood clots or "sticky blood") form in blood vessels, which prove to be fatal if they move within the blood stream. If the thromboses migrate to the brain, they can potentially cause a stroke by blocking the blood supply to the brain.
A large randomized trial that compared induction therapy consisting of oral mycophenolate mofetil with cyclophosphamide therapy in patients with lupus nephritis showed that mycophenolate mofetil was not inferior to cyclophosphamide.  The investigators suggested that mycophenolate mofetil was associated with both a trend toward greater complete remissions and a greater safety profile.  This study’s findings were confirmed with the large, international Aspreva Lupus Management Study (ALMS) trial. 
This gene encodes an adapter protein that acts as a substrate of the T cell antigen receptor (TCR)-activated protein tyrosine kinase pathway. The encoded protein associates with growth factor receptor bound protein 2, and is thought to play a role TCR-mediated intracellular signal transduction. A similar protein in mouse plays a role in normal T-cell development and activation. Mice lacking this gene show subcutaneous and intraperitoneal fetal hemorrhaging, dysfunctional platelets and impaired viability.
People with lupus have a higher risk of CAD. This is partly because people with lupus have more CAD risk factors, which may include high blood pressure, high cholesterol, and type 2 diabetes. The inflammation that accompanies lupus also increases the risk of developing CAD. People with lupus are often less active because of fatigue, joint problems, and/or muscle pain, and this also puts them at risk.
Lupus can affect men and women of any race or age. One in 2,000 people in the United States has lupus. People of African, Asian and Native American descent are more likely to develop lupus than are Caucasians. In addition, the disease develops in Emiratis at an earlier stage compared to Asians and expatriate Arabs working in UEA. Lupus studies also show racial preferences, being more prevalent among Arabs than Asians in the UAE region.
Drug-Induced Lupus Erythematosus, like SLE, can affect many parts of the body. However, Drug-Induced Lupus is caused by an overreaction to certain medications. Studies have shown that removal of the medication may stop disease activity. Drugs most commonly connected with drug-induced lupus are those used to treat chronic conditions, such as seizures, high blood pressure or rheumatoid arthritis.
Other medicines. You may need other medicines to treat illnesses or diseases that are linked to your lupus — such as high blood pressure or osteoporosis. Many people with lupus are also at risk for blood clots, which can cause a stroke or heart attack. Your doctor may prescribe anticoagulants (“blood thinners”), such as warfarin or heparin, to prevent your blood from clotting too easily. You cannot take warfarin during pregnancy.
