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.
The panel concluded that both options (GCs plus CYC and GCs plus RTX) were associated with large benefits and moderate harms in comparison to GCs plus placebo in patients with acute neurological manifestations. No studies comparing these two options were identified. In terms of SLE and severe neurological manifestations, clinical trials with GCs plus CYC focused on both general neurologic manifestations, and on seizures, psychosis, myelitis, peripheral neuropathy, brain stem disease and optic neuritis, specifically. No data were found regarding other neuropsychiatric manifestations. The panel significantly weighted the fact that the certainty of the evidence was better for CYC than RTX and that RTX was only evaluated in refractory patients.
Limitations of the test: Like CRP, the ESR is not specific to lupus. Because there are many causes for a positive result, including infection, the test is not diagnostic for lupus. Nor can it distinguish a lupus flare from an infection. Also, the level doesn't directly correlate with lupus disease activity. So it isn't necessarily useful for monitoring disease activity.
Any of a diverse group of plasma polypeptides that bind antigenic proteins and serve as one of the body’s primary defenses against disease. Two different forms exist. The first group of immunoglobulins lies on the surface of mature B cells, enabling them to bind to thousands of antigens. When the antigens are bound, the B plasma cells secrete the second type of immunoglobulins, antigen-specific antibodies, which circulate in the blood and accumulate in lymphoid tissue, esp. the spleen and lymph nodes, binding and destroying specific foreign antigens and stimulating other immune activity. Antibodies also activate the complement cascade, neutralize bacterial toxins and viruses, and function as opsonins, stimulating phagocytosis.
With variants known as discoid lupus, subacute cutaneous lupus, and systemic lupus erythematosus, lupus is one of several disorders of the immune system considered “autoimmune” in nature. These diseases occur when the immune system malfunctions and turns its infection-defense capabilities against the body, producing antibodies against healthy cells and tissues. These antibodies promote chronic inflammation and can damage organs and tissues. In lupus, these antibodies are known as antinuclear antibodies (ANA) because they target parts of the cell’s nucleus. Experts don’t yet fully understand all of the factors and triggers that cause inflammation and tissue damage in lupus, and research is ongoing.
SLE may cause pericarditis—inflammation of the outer lining surrounding the heart, myocarditis—inflammation of the heart muscle, or endocarditis—inflammation of the inner lining of the heart. The endocarditis of SLE is non-infectious, and is also called (Libman–Sacks endocarditis). It involves either the mitral valve or the tricuspid valve. Atherosclerosis also occurs more often and advances more rapidly than in the general population.
In a study published in 2015, patients with SLE were referred for nutrition counseling with a registered dietician (RD), and 41 of 71 referrals participated in the sessions.8 At the end of the 6-month period, the patients who received nutrition counseling were more likely to have lost weight; decreased their intake of foods high in fat, sodium, and calories; and increased their consumption of fruits, vegetables, fiber, and fish.
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.
The NIH: National Institute of Arthritis and Musculoskeletal and Skin Diseases (2014) suggests that the symptoms may vary dependent on the type of lupus and the person. Symptoms tend to ‘come and go’, ‘flare’ from mild to severe intensity, and new symptoms of lupus can arise at any stage (NIH, 2014). Better Health Channel (n. d.) state that lupus may even become life-threatening, for example, should it damage major organs such as the kidneys or brain.
The removal of plasma from a patient (usually to treat an immmunologically mediated illness such as thrombotic thrombocytopenic purpura or myasthenia gravis) and its replacement with normal plasma. Plasma exchange therapy can also be used to replace excessively viscous plasma in patients with Waldenström macroglobulinemia. Pathological antibodies, immune complexes, and protein-bound toxins are removed from the plasma by plasma exchange. Immunoglobulin infusions are an alternative to plasma exchange when treating some immunological illnesses, including Guillain-Barré syndrome and chronic inflammatory demyelinating polyneuropathy.
Symptoms, causes, and treatment of chronic kidney disease Chronic kidney disease or failure is a progressive loss of kidney function that sometimes occurs over many years. Often the symptoms are not noticeable until the disease is well advanced, so it is essential that people who are at risk of developing kidney problems, such as those with diabetes, have regular check-ups.

Scientists have suspected for years that infections from bacteria, viruses, and other toxins were likely to blame for the development of conditions like lupus. And while they have not been able to identify one single culprit, they have found strong correlations with a number of bacteria and viruses. For example, the Epstein-Barr virus (EBV) has been shown to trigger lupus in some individuals.4
(1) SOC; (2) SOC plus methotrexate (MTX); (3) SOC plus leflunomide (LFN); (4) SOC plus belimumab; (5) SOC plus abatacept (ABT); (6) other options: azathioprine (AZA), mycophenolate mofetil (MMF), cyclosporine A (CsA) or rituximab (RTX) (online supplementary tables S2.1.1, S2.1.4, S2.1.6, S2.1.7, S2.2.11, S2.1.11, S2.1.12, S2.1.14, S2.1.15, S2.1.17, S2.2.1, S2.2.2, S2.2.4, S3.1.1, S3.1.3–S3.1.6, S3.2.1, S3.2.2, S12.2–S12.5, S12.8–S12.10).
Lupus is treated by internal medicine subspecialists called rheumatologists. Depending on whether or not specific organs are targeted, other health specialists who can be involved in the care of patients with lupus include dermatologists, nephrologists, hematologists, cardiologists, pulmonologists, and neurologists. It's not uncommon that a team of such physicians is coordinated by the treating rheumatologist together with the primary care doctor.
The immune response is how your body recognizes and defends itself against bacteria, viruses, and substances that appear foreign and harmful.The immune system protects the body from possibly harmful substances by recognizing and responding to antigens. Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. The immune system recognizes and destroys substances that contain antigens. Your own body’s cells have proteins that are antigens. These include a group of antigens called HLA antigens. Your immune system learns to see these antigens as normal and usually does not react against them.
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.
Fever in patients with systemic lupus erythematosus (SLE) is grounds for hospital admission because of the difficulty of distinguishing a disease flare from infection in these immunocompromised hosts. Patients with SLE are often complement deficient and functionally asplenic; therefore, they are at particular risk for infections with encapsulated organisms. For example, meningococcemia in young females with lupus may be catastrophic.
I believe that we should ALL benefit from regularly working on stress relief! Take care of yourself by adopting stress-relieving strategies, such as exercise, meditation, yoga, art, or whatever works for you. The key is to choose something that you will enjoy and stick with. I personally use a heart rhythm pacer called InnerBalance, an app that coaches you to breathe in line with your heartbeat. Even giving yourself five minutes to sit quietly with a fragrant cup of herbal tea (caffeine-free, of course!) can work wonders for your adrenal glands.
Fertility rates in women with systemic lupus erythematosus (SLE) may be similar to those in the general population. However, the incidence of spontaneous abortion, premature labor, early preeclampsia/eclampsia, fetal growth restriction, and intrauterine death are somewhat higher in women with SLE, [61, 138] especially in those with SSA(Ro)/SSB(La) antibodies, antiphospholipid antibodies,  or lupus nephritis.  One study suggested that women with SLE have fewer live births than the general population.  In this study, decreased live births were associated with exposure to cyclophosphamide and high SLE disease activity.
The panel recommends SOC (GCs and antimalarials (AM)) in addition to an IS (CYC in high or low doses, MMF or TAC) over GCs alone, for induction in patients with SLE-related kidney disease (strong recommendation based on moderate certainty of the evidence). Although more African-American descendants and Hispanic patients responded to MMF than CYC (25), limited access to MMF and TAC in several Latin American countries, due primarily to cost issues, makes CYC the best alternative for induction (high or low dose) in these regions (table 2).
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.
Environment Researchers suspect environmental factors may increase the risk of developing lupus. For example, exposure to sun can cause a lupus rash and some systemic lupus activity, says Stacy Ardoin, MD, a rheumatologist at the Ohio State University Wexner Medical Center in Columbus. Other environmental factors that may contribute to lupus can include some drugs, viral infections, exhaustion, stress, and anything that can cause physical stress to the body (such as surgery, physical harm, injury, pregnancy, or giving birth).
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.
Peripheral neuropathy describes damage to the peripheral nervous system, the vast communications network that transmits information from the brain and spinal cord (the central nervous system) to every other part of the body. Peripheral nerves also send sensory information back to the brain and spinal cord, such as a message that the feet are cold or a finger is burned. Damage to the peripheral nervous system interferes with these vital connections. Like static on a telephone line, peripheral neuropathy distorts and sometimes interrupts messages between the brain and the rest of the body.
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.
Mortality rates for systemic lupus erythematosus are particularly high in children. In a retrospective study26 of Brazilian children, overall mortality during 16 years of follow-up was 24 percent. Death occurred because of infection (58 percent), central nervous system disease (36 percent), and renal disease (7 percent). When disease onset was before the age of 15 years, renal involvement and hypertension predicted mortality.
Systemic sclerosis (SSc): Similar symptoms between SSc and lupus are reflux and Raynaud's disease (when your fingers turn blue or white with cold). One difference between SSc and lupus is that anti-double-stranded DNA (dsDNA) and anti-Smith (Sm) antibodies, which are linked to lupus, don't usually occur in SSc. Another differentiator is that people with SSc often have antibodies to an antigen called Scl-70 (topoisomerase I) or antibodies to centromere proteins.
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.
Lupus takes a long time to diagnose and all the emotional elements of dealing with other peoples misunderstanding adds to the negative feelings. There is really no way to avoid this, just know that you’re not alone in this. My wife has been dealing with Lupus for 30 years and yes there have been difficult times and doctors without understanding or empathy.
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 term undifferentiated connective tissue diseases is used to define conditions characterized by the presence of signs and symptoms suggestive of a systemic autoimmune disease that do not satisfy the classificative criteria for defined connective tissue diseases (CTD) such as systemic lupus erythematosus (SLE), Sjögren’s syndrome (SS), rheumatoid arthritis (RA) and others. A small percentage of patients presenting with an undifferentiated profile will develop during the first year follow up of a full blown CTD, however an average of 75% will maintain an undifferentiated clinical course. These patients may be defined as having a stable undifferentiated connective tissue diseases (UCTD). The most characteristic symptoms of UCTD are represented by arthritis and arthralgias, Raynaud’s phenomenon, leukopenia, while neurological and kidney involvement are virtually absent. Eighty percent of these patients have a single autoantibody specificity, more frequently anti-Ro and anti-RNP antibodies. Stable UCTD are considered as distinct clinical entities and therefore it has been proposed to define those conditions as UCTD. Classificative criteria have also been proposed and a work to better define them is still under way.
The rate of SLE varies between countries, ethnicity, and sex, and changes over time. In the United States, one estimate of the rate of SLE is 53 per 100,000; other estimates range from 322,000 to over 1 million. In Northern Europe the rate is about 40 per 100,000 people. SLE occurs more frequently and with greater severity among those of non-European descent. That rate has been found to be as high as 159 per 100,000 among those of Afro-Caribbean descent. Childhood-onset systemic lupus erythematosus generally presents between the ages of 3 and 15 and is four times more common in girls.
Symptoms vary from person to person, but the typical lupus patient is a young woman experiencing fever, swollen lymph nodes (glands), butterfly-shaped rash on her face, arthritis of the fingers, wrists or other small joints, hair loss, chest pain and protein in the urine. Symptoms usually begin in only one or two areas of the body, but more may develop over time. The most common signs and symptoms of lupus are:
Why the test is used: Between 75% and 90% of people with lupus have a positive anti-dsDNA test. Also, the test is very specific for lupus. Therefore, a positive test can be useful in confirming a diagnosis. For many people, the titer, or level, of the antibodies rises as the disease becomes more active. So, doctors can also use it to help measure disease activity. Also, the presence of anti-dsDNA indicates a greater risk of lupus nephritis, a kidney inflammation that occurs with lupus. So a positive test can alert doctors to the need to monitor the kidneys.
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.
Lupus affects people in many different ways, so there is not one diet which is guaranteed to work for everyone, but the Mediterranean diet (plenty of fruit and vegetables, grains, nuts and seeds, two portions of fish per week and small amounts of meat and dairy produce) is probably the simplest one to follow and is suitable for all the family as it is a pattern of healthy eating.
Corticosteroids. Corticosteroids (prednisone) may help reduce swelling, tenderness, and pain. In high doses, they can calm the immune system. Corticosteroids, sometimes just called “steroids,” come in different forms: pills, a shot, or a cream to apply to the skin. Lupus symptoms usually respond very quickly to these powerful drugs. Once this has happened, your doctor will lower your dose slowly until you no longer need it. The longer a person uses these drugs, the harder it becomes to lower the dose. Stopping this medicine suddenly can harm your body.
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.
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.

Prognosis is typically worse for men and children than for women; however, if symptoms are present after age 60, the disease tends to run a more benign course. Early mortality, within 5 years, is due to organ failure or overwhelming infections, both of which can be altered by early diagnosis and treatment. The mortality risk is fivefold when compared to the normal population in the late stages, which can be attributed to cardiovascular disease from accelerated atherosclerosis, the leading cause of death for people with SLE. To reduce the potential for cardiovascular issues, high blood pressure and high cholesterol should be prevented or treated aggressively. Steroids should be used at the lowest dose for the shortest possible period, and other drugs that can reduce symptoms should be used whenever possible.
The panel suggests SOC alone over adding other immunosuppressant (IS) in adult patients with SLE with MSK manifestations (weak recommendation based on low certainty of the evidence). It suggests also adding either MTX, LFN, belimumab or ABT to those failing to respond to SOC (weak recommendation based on low to moderate certainty of the evidence). Cost and availability may favour MTX (table 1).
In addition to prescribing medications, doctors may also recommend lifestyle changes to help manage lupus. These may include avoidance of sun exposure and paying more attention to managing stress to prevent lupus flares (periods of time when symptoms become problematic). People with lupus should also avoid smoking to help with heart and lung health, Kramer says.
