A primary lymphoid organ located in the mediastinal cavity anterior to and above the heart, where it lies over the superior vena cava, aortic arch, and trachea. The thymus comprises two fused lobes, the right larger than the left. The lobes are partially divided into lobules, each of which has an outer cortex packed with immature and developing T lymphocytes (thymocytes) and an inner medulla containing a looser arrangement of mature T lymphocytes.
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.
Based on the identified evidence the panel concluded that compared with GCs alone, the addition of other IS (CYC, MMF or TAC) is associated with significant benefits, higher remission rates and lower progression rates to end-stage renal disease (ESRD). Head-to-head comparisons between MMF, TAC and high-dose CYC showed that MMF and TAC are associated with less adverse effects than high-dose CYC. Between low and high-dose CYC the balance favours the former because of better safety profile and comparable efficacy, although this conclusion is based on one trial that included predominantly Caucasians. RTX did not provide additional benefits when combined with MMF.
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.
Doctors are tasked with interpreting test results, then correlating them with your symptoms and other test results. It's difficult when patients exhibit vague symptoms and clashing test results, but skillful doctors can consider all of these pieces of evidence and eventually determine whether you have lupus or something else entirely. This may take some time along with trial and error.
B cells are essential for the development and pathogenesis of both systemic and organ-specific autoimmune diseases. Autoreactive B cells are typically thought of as sources of autoantibody, but their most important pathogenetic roles may be to present autoantigens to T cells and to secrete proinflammatory cytokines. A rate-limiting step in the genesis of autoimmunity then is the activation of autoreactive B cells. Here, mechanisms are discussed that normally prevent such activation and how they break down during disease. Integrating classic work with recent insights, emphasis is placed on efforts to pinpoint the precursor cells for autoantibody-secreting cells and the unique stimuli and pathways by which they are activated.
The mission of the National Institute of Arthritis and Musculoskeletal and Skin Diseases is to support research into the causes, treatment, and prevention of arthritis and musculoskeletal and skin diseases; the training of basic and clinical scientists to carry out this research; and the dissemination of information on research progress in these diseases.
The doctor who caused you distress and probably confusion about your situation sounds bipolar. He probably experienced the episode when walking through the door. The basic human instinct is fight or flight when entering a new environment and he seems to have been confused by it. Also maybe he had a patient or personal experience that affected him deeply, this has nothing to do with you or your situation. My wife went through the same unnecessary experience more than once.
One main type of lupus, cutaneous lupus erythematosus, is limited to skin symptoms, including a rash and lesions. That means people with cutaneous lupus, which does not progress and become systemic lupus erythematosus, only experience skin symptoms. People with cutaneous lupus most commonly develop a discoid rash. It appears as round, raised, red patches and can cause scarring, Dr. Caricchio explains. “It’s often confined to small areas above the neck, such as the ears and scalp,” he says. The rash usually does not itch or cause discomfort.
There’s no scientific evidence that avoiding red meat will have an effect on lupus. If you have kidney disease, red meat can give you more protein than your kidneys can handle. If you have high cholesterol or high triglyceride levels, red meat can raise these further. On the other hand, if you have inflammation in your body you need more protein than when you’re healthy. So the bottom line is to eat a well-balanced diet. If you’re not sure how much you should be eating, ask your doctor to refer you to a Registered Dietitian for a consultation.
Lupus can affect men and women of any race or age. One in 2,000 people in the United States has lupus. People of African, Asian and Native American descent are more likely to develop lupus than are Caucasians. In addition, the disease develops in Emiratis at an earlier stage compared to Asians and expatriate Arabs working in UEA. Lupus studies also show racial preferences, being more prevalent among Arabs than Asians in the UAE region.
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.
SLE can also flare during or after pregnancy. Whether flares of SLE are more frequent during pregnancy is controversial. The flares do not seem to be exceedingly more serious than those in nonpregnant patients, although pregnancy outcomes are generally more likely to be complicated. Increased rates of hypertension during pregnancy, premature delivery, unplanned cesarean delivery, postpartum hemorrhage, and maternal venous thromboembolism are all more frequent in women with SLE.
Flare-ups of lupus can cause acute inflammation and damage to various body tissues and can affect the joints, skin, kidneys, heart, lungs, blood vessels, and brain. Some of the most common symptoms are painful or swollen joints, unexplained fever, kidney problems and extreme fatigue. A characteristic red skin rash – called a “malar” or “butterfly” rash because it roughly mimics the insect’s shape – may appear across the nose and cheeks. Rashes may also occur on the face and ears, upper arms, shoulders, chest, and hands. Because many lupus patients are sensitive to sunlight, skin rashes often develop or worsen after sun exposure.
Articular cartilage is the highly specialized connective tissue of diarthrodial joints. Its principal function is to provide a smooth, lubricated surface for articulation and to facilitate the transmission of loads with a low frictional coefficient. Articular cartilage is devoid of blood vessels, lymphatics, and nerves and is subject to a harsh biomechanical environment. Most important, articular cartilage has a limited capacity for intrinsic healing and repair. In this regard, the preservation and health of articular cartilage are paramount to joint health.
“My message to patients is that we can do an excellent job of managing the condition compared to 20 years ago,” 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. With that said, people should never underestimate the serious effects lupus can have, he adds, which is why working with your doctor to manage the condition is so important.
