What does it mean to have the lupus cell?
The LE factor or lupus cell is an autoantibody found in 75% of people with systemic lupus erythematosus.
How are autoimmune and rheumatic diseases diagnosed?
Autoimmune and rheumatic diseases can be difficult to diagnose. People with the same disease can have very different symptoms. A helpful strategy in the diagnosis of these diseases is to find and identify an autoantibody in the person's blood
Why human joints pain?
There are a number of reasons pain in joints is witnessed. The most probable being arthritis, of which there are two types: osteoarthritis and rheumatoid arthritis. The former is due to damage and wear of the synovial membrane in joints, this is a degenerative issue due to age and causes erosion of the cartilage and bone. The latter is a genetically predisposed condition whereby a person's immune system creates an autoantibody which plays a role in the destruction of the synovial membrane, cartilage and bones of joints - a type of autoimmunity.
What are immunological abnormalities in asbestos workers?
Autoimmune disease is the scientific demonstration of abnormalities in invulnerable directive that pilot to tissue smash up by self-reactive lymphocytes and autoantibody, resultant in incapacitating symptoms and bereavement when very important organs are influenced. The cause of most autoimmune ailments continues doubtful, even though ecological factors are strappingly indicated in the course of studies in animal models. Universal autoimmune diseases include general lupus erythematosus, systemic sclerosis and rheumatoid arthritis come into sight to have multifaceted etiologies with gene-environment communications
What do you mean by Rheumatoid arthritis factor?
Rheumatoid factor (RF or RhF) is an antibody that attacs an organism's own tissue. omos often found in About 80% of people with rheumatoid arthritis have detectable rheumatoid factor. Those who do not are said to be "seronegative".Rheumatoid factor can also be a (antibody that precipitates on cooling of a blood sample); it can be either type 2 (monoclonal IgM to polyclonal IgG) or 3 (polyclonal IgM to polyclonal IgG)
What are normal antimyocardial antibody test results?
A positive result means that antimyocardial antibodies are present and that heart disease or damage is likely. Further testing may be needed as other autoantibodies could also be present, causing a false abnormal test.
How many people are diagnosed with diabetes?
Your doctor may suspect that you may have diabetes because of risk factors as it runs in your immediate family, or if you have high levels of blood sugar in your urine. Diabetes may be diagnosed with one of three tests: ● A fasting glucose test ● An oral glucose tolerance test (OGTT) ● The A1c test ● A zinc transporter 8 autoantibody (ZnT8Ab) test In most cases, your doctor will repeat a test that is high in order to confirm the diagnosis and to determine what type of diabetes.
What blood test tube is used to test for lupus?
A variety of blood tests are used to help diagnose lupus but there is no single marker. Examination of blood cells (red, white, platelets) is usually performed. Lupus patients may be anemic, have low white counts, or be low on platelets. A metabolic panel will be done to rule out other diseases or conditions that have symptoms similar to lupus. Sedimentation rate, CRP and ferratin tests will reveal inflammation inside the body. FANA ( fluoresecnt antinuclear antibody), anti double stranded DNA. anti Smith, LE prep, and other autoantibody screenings may be performed. Tests for antiphospholipid antibody syndrome may also be performed. There is no definitive test. 10 million Americans have a positive ANA, but only about 1.5 million have lupus. Of the 1.5 million people with lupus 95-98% will have a negative ANA. The other tests present the same problems. If a person has a positive antiSmith then they do have lupus. But a large percentage of lupus patients do not have this antibody. All in all, there are 118 autoantibodies that may or may not be present.
What diagnostic tools can help diagnose the cause of diarrhea?
Blood tests - Blood tests can sometimes provide information about the cause of chronic diarrhea and the secondary effects of diarrhea on overall health.Complete blood count - A complete blood count (CBC) can detect the anemia that results from long-standing blood loss or inflammation. It can also detect an elevated number of white blood cells, which may signal that diarrhea is being caused by inflammation, infections, allergies, or cancer.Blood chemistry - Blood chemistry tests can detect dehydration and electrolyte (salt and mineral) imbalances, as well as liver problems and nutritional deficiencies.Peptides - Certain rare tumors (such as carcinoid or tumors producing "vasoactive intestinal polypeptide") can produce hormones called peptides that promote diarrhea and can be detected in a blood sample.Antibodies - Tests can detect elevated blood levels of antibodies directed at infectious organisms or antibodies directed at the body's own tissues (called autoantibodies). An example of the latter is an antibody test against tissue transglutaminase. Presence of this autoantibody frequently indicates the presence of celiac disease, a disorder caused by allergy to wheat proteins.Inflammatory markers - The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels are nonspecific markers of inflammation. Elevation of these markers may signal inflammatory bowel disease (Crohn's disease or ulcerative colitis).

What is the pathology of rheumatoid arthritis?
Rheumatoid arthritis, is a chronic, often progressive disease where inflammatory changes occur connective tissues of the body. Inflammation and the resultant thickening of the synovial membranes (the sacs holding the fluid that lubricates the joints) cause irreversible damage to the joint capsule and the articular (joint) cartilage as these structures are replaced by scar like tissue called pannus. RA (Rheumatoid arthritis) is about three times as common in women as in men and afflicts about 1 percent of the adult population in developed coutrys, It primarily affects the middle-aged. (Children may also be affected by a similar disorder known as juvenile rheumatoid arthritis.)Usually rheumatoid arthritis begins by affecting joints of the hands and feet symmetrically then progressing to the wrists, knees, or shoulders; the onset of the disorder is gradual. Pain and stiffness in one or more small joints are usually followed by swelling and heat, accompanied by muscle pain that may last for weeks or months, and may subside suddenly. Joint pain is not always proportionate to the amount of swelling and warmth generated. Fatigue, weakness, and loss of weight are common symptoms. Often, before prominent signs appear, the affected person may complain of coldness of hands and feet, numbness, and tingling, all of which suggest compression of the vasomotor nerve.Active inflammation is first seen in the synovial membranes of the joints, which become red and swollen. Later, a layer of roughened granulation tissue, or pannus, protrudes over the surface of the cartilage. Under the pannus the cartilage is eroded and destroyed. The joints sease in place or (ankylosed) by thick and hardened pannus. This also may cause displacement and deformity of the joints. The skin, bones, and muscles adjacent to the joints atrophy from disuse and destruction. Painful nodules over bony prominences may persist or regress. Complex collections of cells surrounded by lymphocytes in the connective tissue of muscle and nerve bundles cause pressure which leads to pain, the nodular lesions may invade the connective tissue of the blood vessel walls.People that have RA often have characteristic autoantibodies in their blood, one of the pieces of evidence implicating an autoimmune mechanism in the disease process. An autoimmune reaction is an immune reaction against the body's own tissues, and an autoantibody is an antibody that attacks parts of the body These called rheumatoid factor. It is not known what causes the autoimmune reaction, but there is evidence that persons afflicted with the disease have a genetic susceptibility to an environmental agent such as a virus. Once activated by such an agent, a series of immune system reactions causes inflammation.
