Any of a group of immunoglobulin autoantibodies that react with phospholipids, which are one of the primary components of the cell membrane (the other components are glycolipids and steroids). These antibodies are found in patients with a variety of connective tissue and infectious disorders, including systemic lupus erythematosus, the antiphospholipid antibody syndrome, syphilis, and malaria. They cause abnormal blood clotting, thrombocytopenia; and in women of childbearing age, repeated miscarriages. The anticardiolipin antibodies are one type of antiphospholipid antibody.
There are assertions that race affects the rate of SLE. However, a 2010 review of studies which correlate race and SLE identified several sources of systematic and methodological error, indicating that the connection between race and SLE may be spurious. For example, studies show that social support is a modulating factor which buffers against SLE-related damage and maintains physiological functionality. Studies have not been conducted to determine whether people of different racial backgrounds receive differing levels of social support. If there is a difference, this could act as a confounding variable in studies correlating race and SLE. Another caveat to note when examining studies about SLE is that symptoms are often self-reported. This process introduces additional sources of methodological error. Studies have shown that self-reported data is affected by more than just the patients experience with the disease- social support, the level of helplessness, and abnormal illness-related behaviors also factor into a self-assessment. Additionally, other factors like the degree of social support that a person receives, socioeconomic status, health insurance, and access to care can contribute to an individual’s disease progression. Racial differences in lupus progression have not been found in studies that control for the socioeconomic status [SES] of participants. Studies that control for the SES of its participants have found that non-white people have more abrupt disease onset compared to white people and that their disease progresses more quickly. Non-white patients often report more hematological, serosal, neurological, and renal symptoms. However, the severity of symptoms and mortality are both similar in white and non-white patients. Studies that report different rates of disease progression in late-stage SLE are most likely reflecting differences in socioeconomic status and the corresponding access to care. The people who receive medical care have often accrued less disease-related damage and are less likely to be below the poverty line. Additional studies have found that education, marital status, occupation, and income create a social context which contributes to disease progression.
Elevation of the antinuclear antibody (ANA) titer to 1:40 or higher is the most sensitive of the ACR diagnostic criteria. More than 99 percent of patients with systemic lupus erythematosus have an elevated ANA titer at some point,21,41 although a significant proportion of patients may have a negative ANA titer early in the disease.2 However, the ANA test is not specific for systemic lupus erythematosus. A study41 involving 15 international laboratories found that ANA tests in the general population were positive in 32 percent of persons at a 1:40 dilution and in 5 percent of persons at a 1:160 dilution. Rates of positive ANA tests were not affected by age up to 60 years (the upper age limit of the study).41
There is no cure for SLE. Treatments may include NSAIDs, corticosteroids, immunosuppressants, hydroxychloroquine, and methotrexate. Alternative medicine has not been shown to affect the disease. Life expectancy is lower among people with SLE. SLE significantly increases the risk of cardiovascular disease with this being the most common cause of death. With modern treatment about 80% of those affected survive more than 15 years. Women with lupus have pregnancies that are higher risk but are mostly successful.
Corticosteroids. Corticosteroids, such as prednisone, can be helpful in reducing inflammation. Sometimes steroids are used for a few weeks until other slower medications can become effective. Because of their many side effects, the lowest possible dose should be used for the shortest length of time. Usually a corticosteroid is given by mouth as a pill or liquid. However, some forms can be given as an injection into the joint or muscle, or as an IV into a vein. It is important to slowly stop (taper off) steroids instead of stopping them suddenly.
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. 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. 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. 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. 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.
Corticosteroids are more potent than NSAIDs in reducing inflammation and restoring function when the disease is active. Corticosteroids are particularly helpful when internal organs are affected. Corticosteroids can be given by mouth, injected directly into the joints and other tissues, or administered intravenously. Unfortunately, corticosteroids have serious side effects when given in high doses over prolonged periods, and the doctor will try to monitor the activity of the disease in order to use the lowest doses that are safe. Side effects of corticosteroids include weight gain, thinning of the bones and skin, infection, diabetes, facial puffiness, cataracts, and death (necrosis) of the tissues in large joints.
There is no single diagnostic test for systemic lupus. The test you will hear most about is called the antinuclear antibody (ANA) test. This is not a specific test for lupus, however. In fact, a variety of laboratory tests are used to detect physical changes or conditions in your body that can occur with lupus. Each test result adds more information to the picture your doctor is forming of your illness.
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.
Lupus is an incredibly complex autoimmune disease and diagnosing lupus can take a lot of time and many doctor visits. Patients will often get diagnosed with other “overlap” diseases such as rheumadoid arthritis (RA), Sjogren’s Syndrome, scleroderma, fibromyalgia or Raynaud’s Phenomenon even before a diagnosis of lupus is made. This can be incredibly frustrating for you as well as your doctors. Understanding the process of getting a lupus diagnosis is one of the most common questions we get here as well as a main topic in the discussions on our Facebook page and our other social media platforms. The goal of this blog is to give a clear understanding of the diagnosis process and provide the tools needed to go back to your doctor (or a new doctor) armed with the information you need.
Dermatomyositis (DM) and polymyositis (PM): While almost all people with lupus have a positive ANA test, only around 30 percent of people with DM and PM do. Many of the physical symptoms are different as well. For instance, people with DM and PM don't have the mouth ulcers, kidney inflammation, arthritis, and blood abnormalities that people with lupus do.
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 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.
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 aim of this review is to provide an up-to-date overview of treatment approaches for systemic lupus erythematosus (SLE), highlighting the multiplicity and heterogeneity of clinical symptoms that underlie therapeutic decisions. Discussion will focus on the spectrum of currently available therapies, their mechanisms and associated side-effects. Finally, recent developments with biologic treatments including rituximab, epratuzumab, tumor necrosis factor (TNF) inhibitors, and belimumab, will be discussed.
Numerous studies suggest that moderate intake of alcohol may decrease the risks of developing cardiovascular disease problems, increase HDL good cholesterol levels, and may even decrease the risk for certain cancers. However, the sugar it contains will increase your calorie consumption (potentially contributing to weight gain) and regular alcohol consumption may increase the risk for breast cancer.
According to the Mayo Clinic, “People with lupus should eat plenty of fruits, vegetables and whole grains. These foods are rich in vitamins, minerals and essential nutrients that benefit overall health and can help prevent high blood pressure, heart disease, kidney disease, cancer and digestive disorders. Plant-based diets also support a healthy weight because they are naturally low in calories, fat and cholesterol. Fruits and vegetables are particularly high in antioxidants. Antioxidants protect the body by destroying harmful substances that damage cells and tissue and cause heart disease and cancer.” Take a look at our blog, Lupus: the Diet Dilemma for some great tips. While these diets, or eating plans, may have some merit, individual foods should not be the focus. Pay attention to your overall pattern of nutrition. Reducing inflammation is not just about what you eat. Patients should also know that these diets are never meant to be a replacement for the lupus treatments they may already be taking under the close supervision of a medical professional. Until more research is in on the effectiveness of these diets, be practical by getting enough sleep and exercise, and try to maintain a healthy weight. Back to top
Drug-induced lupus erythematosus (DIL) Some drugs can cause lupus, resulting in symptoms such as rash, arthritis, hair loss, and fever. “Once medications are discontinued, the symptoms go away,” says Roberto Caricchio, MD, the interim section chief of rheumatology at Temple University Hospital in Philadelphia and the director of the Temple Lupus Clinic at the Lewis Katz School of Medicine.
Acute cutaneous: This is the type of skin flare that occurs when your SLE is active. Lesions associated with acute cutaneous lupus appear as flattened areas of red skin on the face, reminiscent of a sunburn—the telltale butterfly rash. These lesions can appear on the arms, legs, and body, and are photosensitive. Though the lesions may discolor the skin, they don't scar. Lesions typically appear during a flare or after sun exposure.
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.
Today, physicians treat lupus using a wide variety of medicines, ranging in strength from mild to extremely strong. Prescribed medications will usually change during a person’s lifetime with lupus. However, it can take months—sometimes years—before your health care team finds just the right combination of medicines to keep your lupus symptoms under control.
