Aggrecan is a type of protein known as a proteoglycan, which means it has several sugar molecules attached to it. It is the most abundant proteoglycan in cartilage, a tough, flexible tissue that makes up much of the skeleton during early development. Most cartilage is later converted to bone (a process called ossification), except for the cartilage that continues to cover and protect the ends of bones and is present in the nose, airways, and external ears. Aggrecan attaches to the other components of cartilage, organizing the network of molecules that gives cartilage its strength. These interactions occur at a specific region of the aggrecan protein called the C-type lectin domain (CLD). Because of the attached sugars, aggrecan attracts water molecules and gives cartilage its gel-like structure. This feature enables the cartilage to resist compression, protecting bones and joints. Although its role is unclear, aggrecan affects bone development.
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.
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.
The history of SLE can be divided into three periods: classical, neoclassical, and modern. In each period, research and documentation advanced the understanding and diagnosis of SLE, leading to its classification as an autoimmune disease in 1851, and to the various diagnostic options and treatments now available to people with SLE. The advances made by medical science in the diagnosis and treatment of SLE have dramatically improved the life expectancy of a person diagnosed with SLE.
“I have had severe lupus for over twenty years and find that diet doesn’t really change any symptoms. I eat meat, fish, dairy, gluten and sugar too…all in moderation. I eat lots of fruit and veg and avoid processed foods. The only thing I avoid is alcohol. I guess everyone is different but a well-balanced, healthy diet with exercise (when I’m up to it) is my formula.”
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.
With the vast amount of misinformation available online, Gibofsky often sees patients who went on restrictive diets that are purported to reduce lupus symptoms, which they may have read about on the internet or heard about from a neighbor. “Upon further discussion, I find that they do not actually feel better on the diet and, in fact, they have multiple nutritional deficiencies that could actually be the reason behind their worsening symptoms,” she said.
The American College of Rheumatology (ACR) established eleven criteria in 1982, which were revised in 1997 as a classificatory instrument to operationalise the definition of SLE in clinical trials. They were not intended to be used to diagnose individuals and do not do well in that capacity. For the purpose of identifying people for clinical studies, a person has SLE if any 4 out of 11 symptoms are present simultaneously or serially on two separate occasions.
Anemia is common in children with SLE and develops in about 50% of cases. Low platelet and white blood cell counts may be due to the disease or a side effect of pharmacological treatment. People with SLE may have an association with antiphospholipid antibody syndrome (a thrombotic disorder), wherein autoantibodies to phospholipids are present in their serum. Abnormalities associated with antiphospholipid antibody syndrome include a paradoxical prolonged partial thromboplastin time (which usually occurs in hemorrhagic disorders) and a positive test for antiphospholipid antibodies; the combination of such findings have earned the term "lupus anticoagulant-positive". Another autoantibody finding in SLE is the anti-cardiolipin antibody, which can cause a false positive test for syphilis.
A group of people who review, approve, and monitor the clinical study protocol. Their role is to protect the rights and welfare of human research subjects participating in a study. The group typically includes people with varying backgrounds, including a community member, to make sure that research activities conducted by an organization are completely and adequately reviewed. Also known as an institutional review board (IRB) or ethics committee.
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.
At Benaroya Research Institute at Virginia Mason (BRI), research programs study the cells which regulate lupus to further understand disease pathogenesis - or the development of the disease – translating these findings into therapeutic targets. In addition, clinical trials are ongoing to evaluate novel therapies in this disease. BRI has a Clinical Research Registry people can join to learn about clinical trials that may be appropriate for them.
No overarching diet exists for people with lupus. However, lupus is a systemic disease, so maintaining good nutritional habits will help your body remain as healthy as possible. Generally, doctors recommend a diet composed of about 50% carbohydrates, 15% protein, and 30% fat. However, since people with lupus often experience symptoms like weight loss or gain, inflammation, osteoporosis, kidney disease, high blood pressure, and atherosclerosis, certain specific nutritional concerns may also need to be taken into consideration. If you need help managing your weight or making healthy food choices, please speak with your doctor. S/he can give you more specific information and refer you to a registered dietitian if needed.
A mononuclear phagocytic white blood cell derived from myeloid stem cells. Monocytes circulate in the bloodstream for about 24 hr and then move into tissues, at which point they mature into macrophages, which are long lived. Monocytes and macrophages are one of the first lines of defense in the inflammatory process. This network of fixed and mobile phagocytes that engulf foreign antigens and cell debris previously was called the reticuloendothelial system and is now referred to as the mononuclear phagocyte system (MPS).
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 arthritic symptoms, take a natural anti-inflammatory agent, containing ginger and turmeric. Get the right kind of regular exercise; swimming or water aerobics are best for those who have arthritis symptoms. Investigate traditional Chinese medicine and Ayurvedic medicine, both of which often do well with autoimmune conditions. Definitely try one or more mind/body therapies, such as hypnosis or interactive guided imagery.
Inflammation associated with lupus and other autoimmune reactions largely stems from an overactive immune system and poor gut health. Leaky gut syndrome can develop in those with lupus, which results in small openings in the gut lining opening up, releasing particles into the bloodstream and kicking off an autoimmune cascade. This inflammatory process can wind up increasing the risk for many conditions, including heart disease or hypertension, weight gain, joint deterioration, and bone loss, just to name a few. (5)
If you or a loved one has been diagnosed with the autoimmune disease systemic lupus erythematosus or any of the less common subtypes of lupus, you may be wondering about available treatment options and which ones may be right for you. Because lupus is a chronic disease, doctors work with you to manage symptoms — which can range from mild arthritis and rash to problems with the kidneys and other organs — using a variety of medications and therapies. And the best treatment approach for you might change over time as your symptoms and the condition changes.
