Blood clots are more common in people with lupus. Clots often occur in the legs (called deep venous thrombosis or DVT) and lungs (called pulmonary embolus or PE) and occasionally in the brain (stroke). Blood clots that develop in lupus patients may be associated with the production of antiphospholipid (APL) antibodies. These antibodies are abnormal proteins that may increase the tendency of the blood to clot. Blood can be tested for these antibodies.
When lupus starts affecting other organs of the body, doctors often prescribe drugs that suppress the immune system, says Kramer. (Lupus causes the body’s immune system to mistakenly attack itself. Immunosuppressive medications help stop that from happening.) One such example, is Cytoxan (cyclophosphamide), originally an anticancer drug. It suppresses the immune system and may be used to reduce inflammation of the kidney, or nephritis, says Dr. Kaplan.
Lupus is often missed or misdiagnosed because the symptoms are vague and can match those of other conditions. Generally, a doctor will review your medical history and your family history, and look for signs of systemic inflammation. Because lupus can involve the internal and external organs, a doctor will rely on observation as well as laboratory testing in order to make a lupus diagnosis. There is no one test for lupus–generally, many different criteria will need to come together, and it can take years to reach a diagnosis.
One common early symptom that can be indicative of lupus is a photosensitive rash, meaning a rash that develops in response to sun exposure, particularly on the face and upper arms, says Dr. Kramer. Other early symptoms are unexplained fever and pain, swelling, and stiffness of multiple joints. Complications such as inflammation of the lining surrounding the lungs or heart can also occur early on, he adds.
Below you will find that list, accompanied by questions created by the LFA to help individuals determine whether they should contact a healthcare professional to discuss the potential for having lupus. The LFA suggests discussing the possibility with a doctor if you answer “yes” to more than three of the questions, from your present and past health history.
There is a wide range of diets advertised to help you lose weight quickly or control various chronic diseases, such as lupus. Many people claim to be experts in nutrition yet have limited knowledge and offer no protection to the public. You should be wary of unqualified practitioners who may be offering unproven techniques to diagnose and treat nutritional problems.
Why the test is used: Abnormalities in blood cell counts, including white blood cells and red blood cells, may occur in people with lupus. This may be related to the lupus, lupus treatments, or infection. For example, leukopenia, a decrease in the number of white blood cells, is found in about 50% of people with lupus. Thrombocytopenia, or a low platelet count, occurs in about 50% of people with lupus, as well. Doctors can use this test to monitor these potentially serious problems.
Acute Cutaneous Lupus results in flat red patches on the cheeks and nose called a malar or butterfly rash that looks quite like sunburn. These patches may also appear on the arms, legs, trunk and any other area that is commonly exposed to the sun. Patients with Acute Cutaneous Lupus can also manifest oral ulcers, hives and temporary hair loss. Acute Cutaneous Lupus is more common in people living with SLE.
The immune system must balance between being sensitive enough to protect against infection, and become sensitized to attack the body's own proteins (autoimmunity). During an immune reaction to a foreign stimulus, such as bacteria, virus, or allergen, immune cells that would normally be deactivated due to their affinity for self-tissues can be abnormally activated by signaling sequences of antigen-presenting cells. Thus triggers may include viruses, bacteria, allergens (IgE and other hypersensitivity), and can be aggravated by environmental stimulants such as ultraviolet light and certain drug reactions. These stimuli begin a reaction that leads to destruction of other cells in the body and exposure of their DNA, histones, and other proteins, particularly parts of the cell nucleus. The body's sensitized B-lymphocyte cells will now produce antibodies against these nuclear-related proteins. These antibodies clump into antibody-protein complexes which stick to surfaces and damage blood vessels in critical areas of the body, such as the glomeruli of the kidney; these antibody attacks are the cause of SLE. Researchers are now identifying the individual genes, the proteins they produce, and their role in the immune system. Each protein is a link on the autoimmune chain, and researchers are trying to find drugs to break each of those links.
Due to the variety of symptoms and organ system involvement with SLE, its severity in an individual must be assessed in order to successfully treat SLE. Mild or remittent disease may, sometimes, be safely left untreated. If required, nonsteroidal anti-inflammatory drugs and antimalarials may be used. Medications such as prednisone, mycophenolic acid and tacrolimus have been used in the past.
Since other diseases and conditions appear similar to lupus, adherence to classification can greatly contribute to an accurate diagnosis. However, the absence of four of these criteria does not necessarily exclude the possibility of lupus. When a physician makes the diagnosis of SLE, s/he must exclude the possibility of conditions with comparable symptoms, including rheumatoid arthritis, systemic sclerosis (scleroderma), vasculitis, dermatomyositis and arthritis caused by a drug or virus.
Certain foods, including garlic and alfalfa sprouts, should be avoided by people with lupus. [For a more complete list of items to be avoided, please see the article “Things to Avoided” in the Lupus 101 section.] Recently controversy has also arisen over whether aspartame induces lupus. However, scientists have concluded that there is no evidence to suggest that aspartame causes lupus.
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.
