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.
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.

Vegetarian or vegan diets are okay, but you need to take a multivitamin that includes vitamin B12, as this vitamin can only be obtained through animal products. Otherwise you might develop anemia and nerve damage. Also, it’s important to mix your sources of protein so that you get complete proteins – for example rice and beans, or corn and wheat. Animal proteins, dairy, and eggs are complete proteins, but vegetable proteins are generally low in one or more amino acids, which makes them inadequate as sole sources of protein.
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.
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.
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.
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.
Neurological disorders contribute to a significant percentage of morbidity and mortality in people with lupus. As a result, the neural side of lupus is being studied in hopes of reducing morbidity and mortality rates. One aspect of this disease is severe damage to the epithelial cells of the blood–brain barrier. In certain regions, depression affects up to 60% of women with SLE.
Neonatal lupus is a rare form of temporary lupus affecting a fetus or newborn. It's not true lupus: It occurs when the mother’s autoantibodies are passed to her child in utero. These autoantibodies can affect the skin, heart, and blood of the baby. Fortunately, infants born with neonatal lupus are not at an increased risk of developing SLE later in life.
A diet high in folic acid, such as found in leafy green vegetables, fruits, and fortified breads and cereals, or a folic acid supplement is important if you are taking methotrexate (Rheumatrex). For nausea caused by medications, eat small frequent meals and foods that are easy to digest. Try dry cereals, breads, and crackers. Also avoid greasy, spicy, and acidic foods.
Corticosteroids and immune suppressants: Patients with serious or life-threatening problems such as kidney inflammation, lung or heart involvement, and central nervous system symptoms need more “aggressive” (stronger) treatment. This may include high-dose corticosteroids such as prednisone (Deltasone and others) and drugs that suppress the immune system. Immune suppressants include azathioprine (Imuran), cyclophosphamide (Cytoxan), and cyclosporine (Neoral, Sandimmune). Recently mycophenolate mofetil has been used to treat severe kidney disease in lupus – referred to as lupus nephritis.
The classical period began when the disease was first recognized in the Middle Ages. The term lupus is attributed to 12th-century Italian physician Rogerius Frugard, who used it to describe ulcerating sores on the legs of people. No formal treatment for the disease existed and the resources available to physicians to help people were limited.
Once remission is achieved, start maintenance therapy with azathioprine or mycophenolate mofetil (ie, use less potent agents relative to long-term cyclophosphamide). The ALMS maintenance trial also found that mycophenolate mofetil was superior to azathioprine in the maintenance of the renal response to treatment and in the prevention of relapse in patients with lupus nephritis.  In the MAINTAIN trial, there was a trend toward fewer renal flares in patients receiving mycophenolate mofetil than in those receiving azathioprine  ; however, these results did not reach statistical significance.
Gene regulation is the process of turning genes on and off. During early development, cells begin to take on specific functions. Gene regulation ensures that the appropriate genes are expressed at the proper times. Gene regulation can also help an organism respond to its environment. Gene regulation is accomplished by a variety of mechanisms including chemically modifying genes and using regulatory proteins to turn genes on or off.
Systemic lupus erythematosus is a chronic, recurrent, potentially fatal multisystem inflammatory disorder that can be difficultto diagnose.1,2 The disease has no single diagnostic marker; instead, it is identified through a combination of clinical and laboratory criteria.3 Accurate diagnosis of systemic lupus erythematosus is important because treatment can reduce morbidity4–11 and mortality,12 particularly from lupus nephritis. This article reviews evidence-based recommendations for the diagnosis of systemic lupus erythematosus by primary care physicians.
Other tests for lupus depend on the symptoms patients are experiencing, says Kaplan. For example, chest X-rays and echocardiograms may be necessary to investigate fluid around the lungs and the heart. If doctors suspect nephritis is present, the patient may need a kidney biopsy. Early diagnosis and treatment can help to avoid complications, he adds.
What is known is that lupus is a chronic autoimmune disease (Healthdirect, 2016); meaning, that for people with lupus, their immune system attacks their healthy cells and tissues and not just foreign bodies/invaders (NIH, 2014). Evidently, this can lead to bodily damage. In the most common form of lupus, SLE (systemic lupus erythematosus), nearly all parts of the body can be affected (Healthdirect, 2016).
Make sure that you are drinking sufficient liquid, which may include water, coffee, tea, rooibos, fruit juice, cold drinks and moderate quantities of beer or wine. You need three litres or 10 x 300 ml cups of liquid a day in total. This does NOT mean that you should drink all your regular beverages and then add another extra three litres of water. Remember 10 cups/glasses of LIQUID a day are sufficient.
The mechanism by which foreign antigens are taken into antigen-presenting cells (APCs) and broken up. Part of the antigen is then displayed (presented) on the surface of the APC next to a histocompatibility or self-antigen, activating T lymphocytes and cell-mediated immunity. T lymphocytes are unable to recognize or respond to most antigens without APC assistance.
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.
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.
An antibody, produced by B cells in response to an altered autoantigen on one type of the body’s own cells, that attacks and destroys these cells. Autoantibodies are the basis for autoimmune diseases such as rheumatoid arthritis and diabetes mellitus. Several theories exist about why autoantibodies are formed. The most common theory proposes that AAbs develop as the result of a combination of hereditary and environmental risk factors that cause an autoantigen to be falsely recognized as alien by B cells; as a result, antibodies are produced for its destruction.
"Keeping my weight under control has been a battle. I have tried diets. I know that being overweight increases joint stress and stress on my heart, both of which can be affected by lupus," says LaPlant. Some of the medications that people take for lupus can make it difficult to maintain a healthy weight. Prednisone, one of the most common medications used to treat lupus flares, can increase your appetite and lead to significant weight gain. Regular, low-impact exercise can help offset weight gain and also improve your health in general.
A substance that blocks a type of enzyme called a kinase. Human cells have many different kinases, and they help control important functions, such as cell signaling, metabolism, division, and survival. Certain kinases are more active in some types of cancer cells and blocking them may help keep the cancer cells from growing. Kinase inhibitors may also block the growth of new blood vessels that tumors need to grow.
Since SLE patients can have a wide variety of symptoms and different combinations of organ involvement, no single test establishes the diagnosis of systemic lupus. To help doctors improve the accuracy of the diagnosis of SLE, 11 criteria were established by the American Rheumatism Association. These 11 criteria are closely related to the symptoms discussed above. Some people suspected of having SLE may never develop enough criteria for a definite diagnosis. Other people accumulate enough criteria only after months or years of observation. When a person has four or more of these criteria, the diagnosis of SLE is strongly suggested. Nevertheless, the diagnosis of SLE may be made in some settings in people with only a few of these classical criteria, and treatment may sometimes be instituted at this stage. Of these people with minimal criteria, some may later develop other criteria, but many never do.

Avoiding sunlight in SLE is critical, since sunlight is known to exacerbate skin manifestations of the disease. Avoiding activities which induce fatigue is also important, since those with SLE fatigue easily and it can debilitating. These two problems can lead to people becoming housebound for long periods of time. Drugs unrelated to SLE should be prescribed only when known not to exacerbate the disease. Occupational exposure to silica, pesticides, and mercury can also worsen the disease.
Most patients with systemic lupus erythematosus (unless they’re otherwise advised by their rheumatologist) should be taking an oral antimalarial drug — medications originally used to prevent a malaria infection, but that have been found to help with lupus symptoms, says Dr. Kramer. The antimalarial hydroxychloroquine helps prevent lupus flares, minimizes joint inflammation, and controls fever, fatigue, pleurisy (inflammation of the sac surrounding the lungs), and pericarditis (inflammation of the lining around the heart). The drug is also “the backbone of therapy” for most skin rashes associated with lupus, says Kramer. Mouth sores may also be alleviated with this drug. Chloroquine and quinacrine are other antimalarials drugs used to treat lupus. (3)
