Systemic lupus erythematosus is a chronic, recurrent, potentially fatal multisystem inflammatory disorder that can be difficultto diagnose.1,2 The disease has no single diagnostic marker; instead, it is identified through a combination of clinical and laboratory criteria.3 Accurate diagnosis of systemic lupus erythematosus is important because treatment can reduce morbidity4–11 and mortality,12 particularly from lupus nephritis. This article reviews evidence-based recommendations for the diagnosis of systemic lupus erythematosus by primary care physicians.

An abnormal elevation of temperature. The normal temperature taken orally ranges from about 97.6° to 99.6°F (36.3°C to 37.6°C). Rectal temperature is 0.5° to 1.0°F higher than oral temperature. Normal temperature fluctuates during the day and is lowest in the morning and highest in the late afternoon; these variations are maintained during a fever. The expended basal energy is estimated to be increased about 12% for each degree centigrade of fever.
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.
Research is indicating benefits of rituximab (Rituxan) in treating lupus. Rituximab is an intravenously infused antibody that suppresses a particular white blood cell, the B cell, by decreasing their number in the circulation. B cells have been found to play a central role in lupus activity, and when they are suppressed, the disease tends toward remission. This may particularly helpful for people with kidney disease.
Try to cut down on salt. Ideally you should only be ingesting one teaspoon (5 g) of salt (sodium chloride) a day. Don’t add salt when you cook foods and use as little as possible at table. Use lemon juice, herbs and other spices to give dishes flavour. Read labels on foods to exclude those that have a high salt content. Some medications also contain sodium and may have to be excluded.

A diet high in omega-3 fatty acids may help to mitigate inflammation. Although omega-3s have not been adequately studied in lupus, studies of the general population suggest that these essential fatty acids may also boost mood and improve cardiovascular health. Fish, nuts, and flax are excellent sources of omega-3s and can be easily incorporated into everyday meals. Try to avoid saturated fats, such as those in beef and fried snack foods, since these fats are known to increase the risk of cardiovascular disease and may actually stimulate the immune system.

Although it is known that chronically low complement levels and functional asplenia may result in a low level of susceptibility to infection, it is not known to what degree. [128, 129] Overall, it is likely that the primary reason patients with SLE die of infections is immunosuppressive medications.Stress-dose steroid protocols should be used in patients who are receiving maintenance corticosteroids when they are admitted with infectious or perioperative stress.
SLE is associated with defects in apoptotic clearance, and the damaging effects caused by apoptotic debris. Early apoptotic cells express “eat-me” signals, of cell-surface proteins such as phosphatidylserine, that prompt immune cells to engulf them. Apoptotic cells also express “find-me” signals, to attract macrophages and dendritic cells. When apoptotic material is not removed correctly by phagocytes, they are captured instead by antigen-presenting cells, which leads to development of antinuclear antibodies.[4]
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.

The doctor who caused you distress and probably confusion about your situation sounds bipolar. He probably experienced the episode when walking through the door. The basic human instinct is fight or flight when entering a new environment and he seems to have been confused by it. Also maybe he had a patient or personal experience that affected him deeply, this has nothing to do with you or your situation. My wife went through the same unnecessary experience more than once.

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
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.
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.
Tingible body macrophages (TBMs) – large phagocytic cells in the germinal centers of secondary lymph nodes – express CD68 protein. These cells normally engulf B cells that have undergone apoptosis after somatic hypermutation. In some people with SLE, significantly fewer TBMs can be found, and these cells rarely contain material from apoptotic B cells. Also, uningested apoptotic nuclei can be found outside of TBMs. This material may present a threat to the tolerization of B cells and T cells. Dendritic cells in the germinal center may endocytose such antigenic material and present it to T cells, activating them. Also, apoptotic chromatin and nuclei may attach to the surfaces of follicular dendritic cells and make this material available for activating other B cells that may have randomly acquired self-specificity through somatic hypermutation.[63] Necrosis, a pro-inflammatory form of cell death, is increased in T lymphocytes, due to mitochondrial dysfunction, oxidative stress, and depletion of ATP.[64]
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. [105]

Blood clots are more common in people with lupus. Clots often occur in the legs (called deep venous thrombosis or DVT) and lungs (called pulmonary embolus or PE) and occasionally in the brain (stroke). Blood clots that develop in lupus patients may be associated with the production of antiphospholipid (APL) antibodies. These antibodies are abnormal proteins that may increase the tendency of the blood to clot. Blood can be tested for these antibodies.
There is no permanent cure for SLE. The goal of treatment is to relieve symptoms and protect organs by decreasing inflammation and/or the level of autoimmune activity in the body. The precise treatment is decided on an individual basis. Many people with mild symptoms may need no treatment or only intermittent courses of anti-inflammatory medications. Those with more serious illness involving damage to internal organ(s) may require high doses of corticosteroids in combination with other medications that suppress the body's immune system.

Disease that results when the immune system mistakenly attacks the body’s own tissues. Examples include multiple sclerosis, type 1 diabetes, rheumatoid arthritis, and systemic lupus erythematosus. Autoimmune diseases can affect almost any part of the body, including the heart, brain, nerves, muscles, skin, eyes, joints, lungs, kidneys, glands, the digestive tract, and blood vessels. The classic sign of an autoimmune disease is inflammation, which can cause redness, heat, pain, and swelling.

Granulocytes and monocytes, collectively called myeloid cells, are differentiated descendants from common progenitors derived from hematopoietic stem cells in the bone marrow. Commitment to either lineage of myeloid cells is controlled by distinct transcription factors followed by terminal differentiation in response to specific colony-stimulating factors and release into the circulation. Upon pathogen invasion, myeloid cells are rapidly recruited into local tissues via various chemokine receptors, where they are activated for phagocytosis as well as secretion of inflammatory cytokines, thereby playing major roles in innate immunity.
Chronic diseases are noncommunicable illnesses that are prolonged in duration, do not resolve spontaneously, and are rarely cured completely. Although chronic diseases are more common among older adults, they affect people of all ages and are now recognized as a leading health concern of the nation. Growing evidence indicates that a comprehensive approach to prevention can save tremendous costs and needless suffering.
SLE is an autoimmune disease involving multiple organ systems, a clinical pattern of flares and remissions, and the presence of anti-nuclear autoantibodies. Whereas early symptoms most frequently involve the skin and joints, disease morbidity and mortality are usually associated with cardiovascular events and damage to major organs, particularly the kidneys. Many of the current therapeutic options are considered to be inadequate because of toxicities, accrual of organ damage, and insufficient control of the underlying disease pathology. Improved understanding of SLE pathogenesis and immunology has led to the identification of new treatment targets. Current interest is mainly focused on the targeted immunosuppressive actions provided by biologic therapy. Although the potential long-term beneficial or harmful effects of the new molecular treatments are unclear, their precise molecular targeting may reveal key relationships within the immune system and advance the cause of individualized molecular medicine.
Soy products. Soy products are high in a type of estrogen called phytoestrogen, and estrogen is known to be a risk factor for lupus. In animal studies, researchers noted that a diet high in soy seemed to make lupus symptoms worse. Although there is no definitive evidence that soy products cause lupus symptoms, you should be cautious about including large amounts of soy in your diet.

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.


The Food and Drug Administration is responsible for protecting the public health by ensuring the safety, efficacy, and security of human and veterinary drugs, biological products, and medical devices; and by ensuring the safety of our nation’s food supply, cosmetics, and products that emit radiation. FDA also has responsibility for regulating the manufacturing, marketing, and distribution of tobacco products to protect the public health and to reduce tobacco use by minors.
Antimalarials are another type of drug commonly used to treat lupus. These drugs prevent and treat malaria, but doctors have found that they also are useful for lupus. A common antimalarial used to treat lupus is hydroxychloroquine. It may be used alone or in combination with other drugs and generally is used to treat fatigue, joint pain, skin rashes, and inflammation of the lungs. Clinical studies have found that continuous treatment with antimalarials may prevent flares from recurring.
Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine and body fluids. Maintaining the right balance of electrolytes helps your body’s blood chemistry, muscle action and other processes. Sodium, calcium, potassium, chlorine, phosphate and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink.
Genome-wide association studies (GWAS) revealed regions of linkage that were found on most chromosomes.[52] These studies are useful in identifying the genes that may be responsible for complex diseases such as SLE. Candidate gene loci implicated with SLE include multiple alleles from the HLA region, Fc-gamma receptor, and complement component system.[50] However, association does not prove that a specific form of a gene is responsible for the disease, as there may be other polymorphisms in the region that have a greater association effect.[50] However, because the biological role of most genes are not completely understood, it can be difficult to attribute phenotypic traits to certain genetic polymorphisms. Since SLE is associated with so many genetic regions, it is likely an oligogenic trait, meaning that there are several genes that control susceptibility to the disease.[50] Further complicating our understanding is the association of certain linkages with various ethnic groups.[50]
Anti-dsDNA test:This is the protein directed against the double-stranded DNA, the material making up the genetic code.  This test is very specific for lupus, and can be used to determine a lupus diagnosis. One in every two people with lupus has a positive anti-dsDNA test.  The presence of this anti-dsDNA can indicate a higher risk of lupus nephritis, kidney inflammation that can occur with lupus. This test can confirm the need to closely monitor the kidneys.  Only half the people with lupus have a positive test, so a positive or negative test does not mean you have lupus.

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.


Along with nutritional deficiencies, steroid medications can cause significant weight gain and increased cholesterol, blood glucose, and triglycerides, further underscoring the need for patients with SLE who are taking these agents to follow a healthy diet to counter the effects.6 There are also specific things that individuals with SLE should avoid, including alfalfa sprouts and garlic, which can stimulate an already overactive immune system.7 

Approximately 20% of people with SLE have clinically significant levels of antiphospholipid antibodies, which are associated with antiphospholipid syndrome.[90] 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.[79] If the thromboses migrate to the brain, they can potentially cause a stroke by blocking the blood supply to the brain.


Similarly, a phase III trial of 819 SLE patients who were positive for either antinuclear antibody or anti–double-stranded DNA at baseline screening found that IV belimumab at 10 mg/kg plus standard therapy resulted in a significantly greater SRI score (43.2%) than placebo (33.5%) at 1 year (those who received belimumab 1 mg/kg plus standard therapy had a 40.6% response rate). [118] Overall, the addition of belimumab to standard therapy reduced SLE disease activity and severe flares, and the medication was well tolerated. [118]
Other diseases and conditions that can accompany lupus include fibromyalgia, coronary heart disease, nonbacterial valvular heart disease, pancreatitis, esophagus disease with difficulty swallowing (dysphagia), swollen lymph nodes (lymphadenopathy), liver disease (lupoid hepatitis), infections, and a tendency to spontaneous blood clotting and thrombosis.

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)

Many people with lupus will have some form of a rash, says Roberto Caricchio, MD, the interim section chief of rheumatology at Temple University Hospital and director of the Temple Lupus Clinic in Philadelphia. According to the Lupus Foundation of America, as many as two-thirds of people with lupus experience a skin rash, and estimates suggest that between 40 and 70 percent of people with lupus will notice that their symptoms get worse in the sun or some types of artificial light. (2)


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.

Conventional medicine does not look at the body as a whole, instead viewing it in terms of isolated systems, with a separate doctor for each one. Generally, lupus patients are under the care of a rheumatologist and a doctor who specializes in the area in which they are experiencing symptoms–for example, a nephrologist for your kidneys, and a dermatologist for your skin.
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.
In addition to helping with lupus nephritis, these drugs may be prescribed to reduce inflammation of the heart and the lining surrounding the lungs. Disease-modifying antirheumatic drugs (DMARDs) used for rheumatoid arthritis treatment, such as methotrexate, may be an effective and well-tolerated option for reducing swelling in patients with severe arthritis, adds Caricchio. DMARDs are another type of immunosuppressant.
