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 ACR recommends ANA testing in patients who have two or more unexplained signs or symptoms listed in Table 2.2,20,21 [Reference2—Evidence level C, consensus/expert guidelines] Because of the high rate of false positive ANA titers, testing for systemic lupus erythematosus with an ANA titer or other autoantibody test is not indicated in patients with isolated myalgias or arthralgias in the absence of these specific clinical signs.45 Under most circumstances, a persistently negative ANA titer (less than 1:40) can be assumed to rule out systemic lupus erythematosus.41

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.
SLE is regarded as a prototype disease due to the significant overlap in its symptoms with other autoimmune diseases.[49] This means that it is an important area of continued research and study that is utilizing diverse techniques such as GWAS, microarrays, and murine studies.[50] Further genetic studies of multiple ethnic groups and the creation of disease models incorporating environmental influences will help to increase and refine the understanding of specific genes, linkages, as well as the mechanisms underlying the disease.[51]
Collagen is the major insoluble fibrous protein in the extracellular matrix and in connective tissue. In fact, it is the single most abundant protein in the animal kingdom. There are at least 16 types of collagen, but 80 – 90 percent of the collagen in the body consists of types I, II, and III. These collagen molecules pack together to form long thin fibrils of similar structure. Type IV, in contrast, forms a two-dimensional reticulum; several other types associate with fibril-type collagens, linking them to each other or to other matrix components. At one time it was thought that all collagens were secreted by fibroblasts in connective tissue, but we now know that numerous epithelial cells make certain types of collagens. The various collagens and the structures they form all serve the same purpose, to help tissues withstand stretching.
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.
Arthritis is inflammation of one or more joints and it involves the breakdown of cartilage. Cartilage normally protects a joint, allowing it to move smoothly. Cartilage also absorbs shock when pressure is placed on the joint, such as when you walk. Without the normal amount of cartilage, the bones rub together, causing pain, swelling (inflammation), and stiffness. Usually the joint inflammation goes away after the cause goes away or is treated. Sometimes it does not. When this happens, you have chronic arthritis. Arthritis may occur in men or women. Osteoarthritis is the most common type.
Moderate use of alcohol is usually not a problem for people with lupus, but alcohol can lower the effectiveness of some medications, cause new health problems, and/or can make existing problems worse. For example, non-steroidal anti-inflammatory drugs -- such as aspirin, ibuprofen (Motrin®), naproxen (Naprosyn®), and celecoxib (Celebrex®) -- can cause ulcers and bleeding in the stomach and intestines at any time during treatment; the chance of developing an ulcer or internal bleeding increases with alcohol use. Also, anticoagulant medicines such as warfarin (Coumadin®) and the chemotherapy drug, methotrexate, may not be as effective if you are drinking alcohol.

People with lupus are at great risk of contracting kidney disease. Kidney failure occurs in a minority of patients with lupus nephritis, despite advances in therapy. These patients must undergo dialysis. About one-third of patients who start dialysis during an acute lupus flare will be able to discontinue it within the first year. The remaining two-thirds, and those suffering gradual deterioration of kidney function over several years will require either continual dialysis for life or a kidney transplant.
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.

In addition to the 11 criteria, other tests can be helpful in evaluating people with SLE to determine the severity of organ involvement. These include routine testing of the blood to detect inflammation (for example, the erythrocyte sedimentation rate, or ESR, and the C-reactive protein, or CRP), blood-chemistry testing, direct analysis of internal body fluids, and tissue biopsies. Abnormalities in body fluids (joint or cerebrospinal fluid) and tissue samples (kidney biopsy, skin biopsy, and nerve biopsy) can further support the diagnosis of SLE. The appropriate testing procedures are selected for the patient individually by the doctor.
“There’s no specific diet for lupus, but the Mediterranean-style diet comes close to what’s most ideal," says Sotiria Everett, RD, a clinical assistant professor in the department of family, population, and preventive medicine at Stony Brook School of Medicine in New York. "You want to eat a diet that’s low in fat and sugar and has lots of fruits and vegetables. You should get some of your protein from fish and eat lots of beans and legumes because they’re high in fiber, vitamin B, and iron."
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).
If you plan to add herbs, dietary supplements, or vitamins to your diet, you should discuss your decision with your lupus doctor first. This is especially important as herbs or supplements may interact with medicines used to treat lupus. Herbs or supplements should never be used to replace medicines prescribed to control symptoms of lupus or medication side effects.
Heart: If inflammation affects the heart, it can result in myocarditis and endocarditis. It can also affect the membrane that surrounds the heart, causing pericarditis. Chest pain or other symptoms may result. Endocarditis can damage the heart valves, causing the valve surface to thicken and develop. This can result in growths that can lead to heart murmurs.
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]
Individual test results can also vary from one visit to another, which can be very confusing.  A doctor will take into consideration a combination of factors as well as the test results when diagnosing lupus, and because of this, we encourage you inquire about the ANA and DNA testing, which doctors are often reluctant to give.  These two tests together can create a clearer picture of whether the diagnosis could be lupus.  Again, we must remind you that just because you test negative today, it does not mean that you won’t test positive tomorrow.

Anitphospholipid Antibodies (APLs): Phospholipids are antibodies that are present in approximately one out of every two people with lupus.  A positive test can help confirm diagnosis as well as help identify women with lupus who have certain risks (like blood clots and miscarriage) that would require preventative treatment and monitoring. Note that the presence of phospholipids also occurs in people without lupus and therefore, there presence alone is not enough for a lupus diagnosis.

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.
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
Lupus is a chronic autoimmune condition in which the immune system attacks the body’s own healthy tissue and organs. Depending on the specific patient, lupus can cause high levels of persistent inflammation that can negatively affect various parts of the body. Lupus patients often experience tissue damage that affects the heart, joints, brain, kidneys, lungs and endocrine glands (such as the adrenals and thyroid gland). Although it’s not completely known why this happens, lupus risk factors are believed to include: (2)
Sometimes changes in blood counts may contribute to symptoms of fatigue (low red blood cell count, anemia), serious infections (low white blood cell count), or easy bruising (low platelet count). However, many patients do not have symptoms that indicate blood abnormalities, so it is important for lupus patients to have periodic blood tests in order to detect any problems.

Many women with lupus ask "it safe for me to get pregnant?" or "can I have a healthy pregnancy?" Pregnancy is possible in most patients with lupus, but complications are frequent. Anyone with lupus should be considered to have a high risk for health complications during pregnancy. When a woman with lupus becomes pregnant or is planning to become pregnant, she should get a referral for appropriate, specialized care. Lupus patients who are positive for aPL are at high risk of miscarriage, while patients with anti-Ro/SSA and anti-La/SSB antibodies are at risk for delivering a child with neonatal lupus.
That being said, many physicians support the following of any nutritional plans that are designed to fight inflammation and support the immune system. According to the Department of Health and Human Services and American Heart Association, chronic inflammation might cause diseases such as atherosclerosis, arthritis, osteoporosis, Alzheimer’s disease, food intolerances, diabetes, fibromyalgia, heart disease and in some cases even cancer. It also accelerates the aging process. Nutrition is a very powerful way to protect your cells from inflammation, thus the connection. Lupus, like any other auto-immune disease is different for each individual. While something may work for one person, it may not work for another. In general, it is a good idea for people with autoimmune disorders to discuss any major dietary changes with their doctor beforehand. We are writing this blog primarily in order to provide information and respond to the conversations occurring on our social media platforms with regards to these two diets. Let’s begin by discussing the definitions of each. Back to top

Elevated expression of HMGB1 was found in the sera of people and mice with systemic lupus erythematosus, high mobility group box 1 (HMGB1) is a nuclear protein participating in chromatin architecture and transcriptional regulation. Recently, there is increasing evidence HMGB1 contributes to the pathogenesis of chronic inflammatory and autoimmune diseases due to its inflammatory and immune stimulating properties.[69]

Angiogenesis is the growth of blood vessels from the existing vasculature. It occurs throughout life in both health and disease, beginning in utero and continuing on through old age. No metabolically active tissue in the body is more than a few hundred micrometers from a blood capillary, which is formed by the process of angiogenesis. Capillaries are needed in all tissues for diffusion exchange of nutrients and metabolites. Changes in metabolic activity lead to proportional changes in angiogenesis and, hence, proportional changes in capillarity. Oxygen plays a pivotal role in this regulation. Hemodynamic factors are critical for survival of vascular networks and for structural adaptations of vessel walls.


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.
An increase in the size of an organ, structure, or the body due to growth rather than tumor formation. This term is generally restricted to an increase in size or bulk that results not from an increase in the number of cells but from an increase in a cellular component, e.g., proteins. It applies to any increase in size as a result of functional activity.
A common neurological disorder people with SLE have is headache,[33] although the existence of a specific lupus headache and the optimal approach to headache in SLE cases remains controversial.[34] Other common neuropsychiatric manifestations of SLE include cognitive dysfunction, mood disorder, cerebrovascular disease,[33] seizures, polyneuropathy,[33] anxiety disorder, psychosis, depression, and in some extreme cases, personality disorders.[35] Steroid psychosis can also occur as a result of treating the disease.[31] It can rarely present with intracranial hypertension syndrome, characterized by an elevated intracranial pressure, papilledema, and headache with occasional abducens nerve paresis, absence of a space-occupying lesion or ventricular enlargement, and normal cerebrospinal fluid chemical and hematological constituents.[36]

In addition to the 11 criteria, other tests can be helpful in evaluating people with SLE to determine the severity of organ involvement. These include routine testing of the blood to detect inflammation (for example, the erythrocyte sedimentation rate, or ESR, and the C-reactive protein, or CRP), blood-chemistry testing, direct analysis of internal body fluids, and tissue biopsies. Abnormalities in body fluids (joint or cerebrospinal fluid) and tissue samples (kidney biopsy, skin biopsy, and nerve biopsy) can further support the diagnosis of SLE. The appropriate testing procedures are selected for the patient individually by the doctor.
One of several different tests used to evaluate the condition of the respiratory system. Measures of expiratory flow and lung volumes and capacities are obtained. The forced vital capacity is one of the more important pulmonary function tests; it provides a measure of the amount of air that can be maximally exhaled after a maximum inspiration and the time required for that expiration. Pulmonary function tests can also determine the diffusion ability of the alveolar-capillary membrane.

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).
Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
Patients of African-American or African descent did not show significant responses to belimumab in phase III post-hoc analysis, but those studies were not powered to assess for this effect; in a phase II trial, blacks had a greater treatment response. These results indicate that the benefits of belimumab in SLE patients remain inconclusive and that further investigation is needed. Patients with severe active lupus nephritis or CNS lupus or patients previously treated with other biologics or cyclophosphamide have been excluded from participation in early trials.

Recently, there is increasing evidence HMGB1 contributes to the pathogenesis of chronic inflammatory and autoimmune diseases due to its inflammatory and immune stimulating properties.[69]

Another common comorbidity with SLE is osteoporosis; researchers have found an increased risk of fracture and bone loss in SLE. Experts attribute this to several factors, including glucocorticoid medications that can lead to bone loss, inactivity due to symptoms such as pain and fatigue, and possibly the disease activity itself. In addition, women comprise approximately 90% of people with SLE, adding to their generally elevated osteoporosis risk.5
The medical doctors who treat lupus are rheumatologists who specialize in arthritis and other inflammatory disorders. However, depending on the individual, case treatment may involve a wide range of health professionals including clinical immunologists (doctors specializing in immune system disorders), nurses, psychologists, social workers, nephrologists (kidney disease specialists), hematologists (specialists in blood disorders), dermatologists, and neurologists.
A. Chemotherapy can cause a variety of difficult side effects, such as nausea and vomiting. But the chemo drugs used to treat lupus are often gentler than those used to treat cancer, so the side effects aren't as severe. But any type of chemo can harm a woman's fertility by putting her in early menopause, Gilkeson said. While cancer patients sometimes bank their sperm or eggs in order to preserve their future fertility, people with lupus may not have this option, because doctors often want to begin chemo as quickly as possible.

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.[54][10]


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]

In addition to the 11 criteria, other tests can be helpful in evaluating people with SLE to determine the severity of organ involvement.

Abnormalities in body fluids (joint or cerebrospinal fluid) and tissue samples (kidney biopsy, skin biopsy, and nerve biopsy) can further support the diagnosis of SLE.

There is a wide range of diets advertised to help you lose weight quickly or control various chronic diseases, such as lupus. Many people claim to be experts in nutrition yet have limited knowledge and offer no protection to the public. You should be wary of unqualified practitioners who may be offering unproven techniques to diagnose and treat nutritional problems.

Foot pain may be caused by injuries (sprains, strains, bruises, and fractures), diseases (diabetes, Hansen disease, and gout), viruses, fungi, and bacteria (plantar warts and athlete's foot), or even ingrown toenails. Pain and tenderness may be accompanied by joint looseness, swelling, weakness, discoloration, and loss of function. Minor foot pain can usually be treated with rest, ice, compression, and elevation and OTC medications such as acetaminophen and ibuprofen. Severe pain should be treated by a medical professional.


Thinning hair is often one of the first symptoms of lupus. Hair loss is the result of inflammation of the skin and scalp. Some people with lupus lose hair by the clump. More often, hair thins out slowly. Some people also have thinning of the beard, eyebrows, eyelashes, and other body hair. Lupus can cause hair to feel brittle, break easily, and look a bit ragged, earning it the name “lupus hair.”
Therefore, “maintaining good bone health is an area of concern for people with lupus, and a diet rich in calcium and vitamin D can help counteract bone-damaging effects,” Gibofsky explained. These foods might include “milk, light ice cream or frozen yogurt, cottage cheese, pudding, almonds, broccoli, fortified cereal, oranges, yogurt, hard cheese, soybeans and soy milk, navy beans, oysters, sardines, and spinach,” according to experts at Johns Hopkins University School of Medicine.6
Useful medication for the disease was first found in 1894, when quinine was first reported as an effective therapy. Four years later, the use of salicylates in conjunction with quinine was noted to be of still greater benefit. This was the best available treatment until the middle of the twentieth century, when Hench discovered the efficacy of corticosteroids in the treatment of SLE.[121]

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.
Note: Ultimately, in patients with kidney disease from systemic lupus erythematosus (lupus nephritis), a kidney biopsy may be necessary to both define the cause of the kidney disease as being lupus-related as well as to determine the stage of the kidney disease in order to optimally guide treatments. Kidney biopsies are often performed by fine-needle aspiration of the kidney under radiology guidance, but in certain circumstances, a kidney biopsy can be done during an open abdominal operation.
Cardiac tamponade is pressure on the heart that occurs when blood or fluid builds up in the space between the heart muscle (myocardium) and the outer covering sac of the heart (pericardium). This prevents the heart ventricles from expanding fully. The excess pressure from the fluid prevents the heart from working properly. As a result, the body does not get enough blood.

Many women with lupus ask "it safe for me to get pregnant?" or "can I have a healthy pregnancy?" Pregnancy is possible in most patients with lupus, but complications are frequent. Anyone with lupus should be considered to have a high risk for health complications during pregnancy. When a woman with lupus becomes pregnant or is planning to become pregnant, she should get a referral for appropriate, specialized care. Lupus patients who are positive for aPL are at high risk of miscarriage, while patients with anti-Ro/SSA and anti-La/SSB antibodies are at risk for delivering a child with neonatal lupus.


A genetic disorder is a disease caused in whole or in part by a change in the DNA sequence away from the normal sequence. Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes, the structures that carry genes).
Only one population-based screening study13 of systemic lupus erythematosus was identified. This study reported a prevalence of 200 cases per 100,000 women (18 to 65 years of age) in England. One review14 estimated the overall U.S. prevalence of definite systemic lupus erythematosus plus incomplete systemic lupus erythematosus (disease meeting only some diagnostic requirements for systemic lupus erythematosus) to be 40 to 50 cases per 100,000 persons.
Kidney inflammation in SLE (lupus nephritis) can cause leakage of protein into the urine, fluid retention, high blood pressure, and even kidney failure. This can lead to further fatigue and swelling (edema) of the legs and feet. With kidney failure, machines are needed to cleanse the blood of accumulated waste products in a process called dialysis.
Systemic lupus erythematosus is a multisystem inflammatory disease that is often difficult to diagnose. Before the diagnosis can be established, four of 11 clinical and laboratory criteria must be met. Antinuclear antibody titer is the primary laboratory test used to diagnose systemic lupus erythematosus. Because of the low prevalence of the disease in primary care populations, the antinuclear antibody titer has a low predictive value in patients without typical clinical symptoms. Therefore, as specified by the American College of Rheumatology, this titer should be obtained only in patients with unexplained involvement of two or more organ systems. Pa tients with an antinuclear antibody titer of 1:40 and characteristic multiorgan system involvement can be diagnosed with systemic lupus erythematosus without additional testing; however, patients with an antibody titer of 1:40 who fail to meet full clinical criteria should undergo additional testing, including tests for antibody to doublestranded DNA antigen and antibody to Sm nuclear antigen. While an antinuclear antibody titer of less than 1:40 usually rules out systemic lupus erythematosus, patients with persistent, characteristic multisystem involvement may be evaluated for possible antinuclear antibody–negative disease.

For instance, a dermatologist for cutaneous lupus (skin disease), a cardiologist for heart disease, a nephrologist for kidney disease, a neurologist for brain and nervous system disease, or a gastroenterologist for gastrointestinal tract disease. A woman with lupus who is considering a pregnancy needs an obstetrician who specializes in high-risk pregnancies.
