Sjogren’s syndrome is a disease that causes dryness in your mouth and eyes. It can also lead to dryness in other places that need moisture, such as your nose, throat and skin. Most people who get Sjogren’s syndrome are older than 40. Nine of 10 are women. Sjogren’s syndrome is sometimes linked to rheumatic problems such as rheumatoid arthritis. In Sjogren’s syndrome, your immune system attacks the glands that make tears and saliva. It may also affect your joints, lungs, kidneys, blood vessels, digestive organs and nerves. The main symptoms are:
Infections and diseases of the cardiovascular, renal, pulmonary, and central nervous systems are the most frequent causes of death in patients with systemic lupus erythematosus.8,23,32–37 Since the 1950s, the five-year survival rate for patients with systemic lupus erythematosus has increased from 50 percent to a range of 91 to 97 percent.8,23,32–34,38,39 It is not known how much of this increase in survival is due to improved management versus diagnosis of earlier and milder disease. Higher mortality rates are associated with seizures, lupus nephritis, and azotemia.36,37,40

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.

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.[65] DNAse1 mutations in lupus have so far only been found in some Japanese cohorts.[66]

In addition to hormonal mechanisms, specific genetic influences found on the X chromosome may also contribute to the development of SLE. Studies indicate that the X chromosome can determine the levels of sex hormones. A study has shown an association between Klinefelter syndrome and SLE. XXY males with SLE have an abnormal X–Y translocation resulting in the partial triplication of the PAR1 gene region.[104]
Kidney involvement in people with lupus is potentially life threatening and may occur in up to half of lupus patients. Kidney problems may become apparent when lupus patients feel ill with arthritis, have a rash, fever and weight loss. Less often, kidney disease may occur when there are no other symptoms of lupus. Kidney disease itself usually does not produce symptoms until it is in the advanced stages. It is important that kidney disease be diagnosed early and treated appropriately. The earliest signs of kidney disease are apparent from a urinalysis.
Erythrocyte Sedimentation Rate:  This is a blood test that is used to determine the rate at which red blood cells settle to the bottom of a tube in one hour’s time.  If the rate is faster than normal, it may be an indication of a systemic disease, like lupus.  It is important to note that this sedimentation rate, or rate of settling, does not specifically indicate lupus, but can be elevated if other inflammatory conditions are present like cancer or an infection.
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.
Patient global assessment (PGA) is one of the most widely used PROs in RA practice and research and is included in several composite scores such as the 28-joint Disease Activity Score (DAS28). PGA is often assessed by a single question with a 0–10 or 0–100 response. The content can vary and relates either to global health (e.g., how is your health overall) or to disease activity (e.g., how active is your arthritis).
The mission of the National Institute of Arthritis and Musculoskeletal and Skin Diseases is to support research into the causes, treatment, and prevention of arthritis and musculoskeletal and skin diseases; the training of basic and clinical scientists to carry out this research; and the dissemination of information on research progress in these diseases.

Normally, our immune system produces proteins called antibodies that protect the body from these foreign invaders. When you have lupus, your immune system cannot tell the difference between these foreign invaders and your body’s healthy tissues, so autoantibodies are made that damage and destroy healthy tissue (auto means self and anti means against, so autoantibody means against self). These autoantibodies cause inflammation, pain, and damage in various parts of the body.
Alfalfa seeds and sprouts, green beans, peanuts, soybeans, and snow peas contain a substance that has been shown to trigger lupus flare-ups in some patients (although not all). Negative reactions caused by these foods experienced by lupus patients can include antinuclear antibodies in the blood, muscle pains, fatigue, abnormal immune system function and kidney abnormality. These symptoms are believed to be caused by the amino acid L-canavanine. (7)
Lupus pregnancy deserves special review because it presents unique challenges. Pregnant women with SLE are considered high-risk pregnancies. These pregnancies require interactive monitoring generally by a skilled rheumatologist together with an obstetrician expert in high-risk pregnancies. Women with SLE who are pregnant require close observation during pregnancy, delivery, and the postpartum period. This includes fetal monitoring by the obstetrician during later pregnancy. These women can have an increased risk of miscarriages (spontaneous abortions) and can have flares of SLE during pregnancy. The presence of phospholipid antibodies, such as cardiolipin antibodies or lupus anticoagulant, in the blood can identify people at risk for miscarriages. Cardiolipin antibodies are associated with a tendency toward blood clotting. Women with SLE who have cardiolipin antibodies or lupus anticoagulant may need blood-thinning medications (aspirin with or without heparin) during pregnancy to prevent miscarriages. Other reported treatments include the use of intravenous gamma globulin for selected people with histories of premature miscarriage and those with low blood-clotting elements (platelets) during pregnancy. Pregnant women who have had a previous blood-clotting event may benefit by continuation of blood-thinning medications throughout and after pregnancy for up to six to 12 weeks, at which time the risk of clotting associated with pregnancy seems to diminish. Plaquenil has now been found to be safe for use to treat SLE during pregnancy. Corticosteroids, such as prednisone, are also safely used to treat certain manifestation of lupus during pregnancy.

Neutrophils, 55% to 70% of all leukocytes, are the most numerous phagocytic cells and are a primary effector cell in inflammation. Eosinophils, 1% to 3% of total leukocytes, destroy parasites and are involved in allergic reactions. Basophils, less than 1% of all leukocytes, contain granules of histamine and heparin and are part of the inflammatory response to injury. Monocytes, 3% to 8% of all leukocytes, become macrophages and phagocytize pathogens and damaged cells, esp. in the tissue fluid. Lymphocytes, 20% to 35% of all leukocytes, have several functions: recognizing foreign antigens, producing antibodies, suppressing the immune response to prevent excess tissue damage, and becoming memory cells.

Nitrogen in the blood in the form of urea, the metabolic product of the breakdown of amino acids used for energy production. The normal concentration is about 8 to 18 mg/dL. The level of urea in the blood provides a rough estimate of kidney function. Blood urea nitrogen levels may be increased in the presence of dehydration, decreased renal function, upper gastrointestinal bleeding, or treatment with drugs such as steroids or tetracyclines.
Raynaud’s phenomenon is a condition in which the small blood vessels in the fingers and toes spasm, limiting circulation, says Dr. Kaplan. People with Raynaud’s are extremely sensitive to cold temperatures and, in those conditions, will often notice a loss of circulation and loss of color in their digits much more quickly than people without the condition. Raynaud’s affects about a third of people with lupus and can cause color loss in the fingers and toes, which first turn blue, followed by red. (9)
These conditions may be treated with high-dose intravenous steroids and cytotoxic therapy such as cyclophosphamide. Strokes, acute myocardial infarctions, and pulmonary emboli occurring as complications of SLE are managed in the same way as they are in patients without SLE. In patients who present with fever, it may be necessary to limit immunosuppression to steroids and to empirically treat for an infection until culture results have been received.
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]
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. [61]
Clinical studies that are no longer recruiting participants because they have enough participants already, because they are completed, or because they have been stopped for some reason. This also describes studies with very specific eligibility criteria that recruit participants by invitation only. Recruitment statuses for closed studies appear in red text in search results and study records.
Preventive measures are necessary to minimize the risks of steroid-induced osteoporosis and accelerated atherosclerotic disease. [146] The American College of Rheumatology (ACR) Guidelines for the prevention of glucocorticoid-induced osteoporosis suggest the use of traditional measures (eg, calcium, vitamin D) and the consideration of prophylactic bisphosphonate therapy.

Testing for antibody to double-stranded DNA antigen (anti-dsDNA) and antibody to Sm nuclear antigen (anti-Sm) may be helpful in patients who have a positive ANA test but do not meet full criteria for the diagnosis of systemic lupus erythematosus. AntidsDNA and anti-Sm, particularly in high titers, have high specificity for systemic lupus erythematosus, although their sensitivity is low. Therefore, a positive result helps to establish the diagnosis of the disease, but a negative result does not rule it out.46 The CAP guideline recommends against testing for other autoantibodies in ANA-positive patients, because there is little evidence that these tests are of benefit.46

Articular cartilage is the highly specialized connective tissue of diarthrodial joints. Its principal function is to provide a smooth, lubricated surface for articulation and to facilitate the transmission of loads with a low frictional coefficient. Articular cartilage is devoid of blood vessels, lymphatics, and nerves and is subject to a harsh biomechanical environment. Most important, articular cartilage has a limited capacity for intrinsic healing and repair. In this regard, the preservation and health of articular cartilage are paramount to joint health.
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]
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".

SLE-associated skin manifestations can sometimes lead to scarring. In discoid lupus, only the skin is typically involved. The skin rash in discoid lupus often is found on the face and scalp. It usually is red and may have raised borders. Discoid lupus rashes are usually painless and do not itch, but scarring can cause permanent hair loss (alopecia). Over time, 5%-10% of those with discoid lupus may develop SLE.
Corticosteroids also can cause or worsen osteoporosis, a disease in which bones become fragile and more likely to break. If you have osteoporosis, you should eat foods rich in calcium every day to help with bone growth. Examples are dark green, leafy vegetables (spinach, broccoli, collard greens), milk, cheese, and yogurt or calcium supplements that contain Vitamin D.
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.
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.”

People with SLE need more rest during periods of active disease. Researchers have reported that poor sleep quality was a significant factor in developing fatigue in people with SLE. These reports emphasize the importance for people and physicians to address sleep quality and the effect of underlying depression, lack of exercise, and self-care coping strategies on overall health. During these periods, carefully prescribed exercise is still important to maintain muscle tone and range of motion in the joints.
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]
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.
Vitamins. Vitamin E, zinc, vitamin A, and the B vitamins are all beneficial in a lupus diet. Vitamin C can increase your ability to absorb iron and is a good source of antioxidants. Vitamin D is especially important for people with lupus because lupus patients need to avoid the sun, and that can result in lower absorption of vitamin D. Calcium and vitamin D are known to help reduce the risk of osteoporosis, which is common in people with lupus. Your doctor may also recommend that you take calcium and vitamin D supplements to help protect your bones. Current studies are specifically exploring whether or not vitamin D may even help relieve lupus symptoms.

In Sjogren’s syndrome, your immune system attacks the glands that make tears and saliva. It may also affect your joints, lungs, kidneys, blood vessels, digestive organs and nerves. The main symptoms are:

The principal receptors on animal cells for binding most extracellular matrix proteins—including collagens, fibronectin, and laminins—are the integrins. Integrins, like other cell adhesion molecules, differ from cell-surface receptors for hormones and for other extracellular soluble signal molecules in that they usually bind their ligand with lower affinity and are usually present at about tenfold to a hundredfold higher concentration on the cell surface. If the binding were too tight, cells would presumably become irreversibly glued to the matrix and would be unable to move—a problem that does not arise if attachment depends on large numbers of weak adhesions. This is an example of the “Velcro principle” mentioned earlier. Like other transmembrane cell adhesion proteins, however, integrins do more than just attach a cell to its surroundings. They also activate intracellular signaling pathways that communicate to the cell the character of the extracellular matrix that is bound.
It’s been found that low levels of vitamin D might be associated with increased risk of autoimmune conditions and other chronic diseases, according to a report published in the International Journal of Rheumatology. (8) If you don’t spend much time outdoors, especially during the winter, talk to your doctor about taking a supplement to prevent vitamin D deficiency.

In its simplest definition, the CBC is used to measure red and white blood cell count, the total amount of hemoglobin in the blood, hematocrit (the amount of blood composed of red blood cells), and mean corpuscular volume (the size of red blood cells). The CBC can also count additional blood cell types like neutrophils, eosinophils, basophils, lymphocytes, monocytes, and platelets.

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.
Genetics Doctors and researchers believe a genetic predisposition may contribute to the development of lupus, says Kaplan. Dozens of genetic variations have been found to be associated with the disease, affecting who gets it and how severe those cases are, according to the Lupus Foundation of America. That means the disease is hereditary, making parents more likely to pass it to their children. But just because you are genetically predisposed to the condition, doesn’t necessarily mean you’ll get it.

Libman-Sacks endocarditis is the most characteristic cardiac manifestation of lupus. It is characterized by clusters of verrucae on the ventricular surface of the mitral valve. These lesions consist of accumulation of immune complexes, platelets, and mononuclear cells. This can lead to heart failure, valvular dysfunction, emboli, and secondary infective endocarditis. Diagnosis is best made via echocardiography, which may reveal the characteristic valvular masses (arrows). IVS = interventricular septum; LA = left atrium; LV = left ventricle.
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)
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.[49] Further compounding our understanding of the etiology of the disease is the involvement of several organ systems.[50] Genetic studies of the rates of disease in families supports the genetic basis of this disease with a heritability of >66%.[51] 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.[51]

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).

There have also been case reports of patients with severe refractory SLE in which off-label use of rituximab showed benefits with tolerable safety profiles. [120, 121, 122] For example, in a retrospective study of 115 patients with severe or refractory SLE, 40% of patients had a complete response and 27% had a partial response, as measured by BILAG scores recorded 6 months after the first rituximab treatment. [123]
Inflammation associated with lupus can cause stiffness, swelling, pain, and warmth of the joints, most commonly in the fingers, hands, elbows, ankles, and toes. (8) Most people with lupus will experience joint inflammation at some point, says Caricchio. For many people, joint pain is one of the first symptoms of the disease that they’ll notice and report.
People with SLE have intense polyclonal B-cell activation, with a population shift towards immature B cells. Memory B cells with increased CD27+/IgD—are less susceptible to immunosuppression. CD27-/IgD- memory B cells are associated with increased disease activity and renal lupus. T cells, which regulate B-cell responses and infiltrate target tissues, have defects in signaling, adhesion, co-stimulation, gene transcription, and alternative splicing. The cytokines B-lymphocyte stimulator (BLys), interleukin 6, interleukin 17, interleukin 18, type I interferons, and tumor necrosis factor α (TNFα) are involved in the inflammatory process and are potential therapeutic targets.[4][60][61]
These are used in packaged/processed products and often to fry foods. Cooking at home more and avoiding fast foods, processed meats, and packaged sweets or cheeses can help you decrease your intake. Some people with lupus have a hard time metabolizing saturated fats and should limit sources like cheese, red meat and creamy foods if they causes symptoms to worsen.
Contraception and family planning are important considerations given the risks of disease flare with exogenous estrogens and pregnancy and with the teratogenic risks of some SLE drugs. Estrogen therapies have typically been avoided to prevent disease flares; progesterone-only contraception is more often considered. [144] However, studies have suggested that oral estrogen-containing contraceptives may not be associated with disease flares or thrombosis risk in patients with mild lupus without antiphospholipid antibodies. [52, 145]
Gluten can also lead to what’s known as molecular mimicry. The gluten protein, gliadin, resembles many of your body’s own tissues, particularly thyroid tissue. If you have Celiac disease, gluten intolerance, or a leaky gut, your immune system releases gliadin antibodies every time you eat gluten. Because gliadin looks so similar to your own tissues, sometimes these antibodies mistakenly attack other organs and systems, from the skin to the thyroid to the brain. This case of mistaken identity often leads to full-blown autoimmune disease.
