Myositis meaning

Causes of Myositis Myositis is caused by any condition that leads to Inflammatory conditions. Conditions causing inflammation throughout the body may affect the muscles, causing myositis. Many of these causes are autoimmune conditions, in which the body attacks its own tissues. Inflammatory conditions causing potentially severe myositis include: • Dermatomyositis • Polymyositis • Inclusion body myositis Other inflammatory conditions tend to cause milder forms of myositis, including: • Lupus • • Rheumatoid arthritis Inflammatory conditions are often the most serious myositis causes, requiring long-term treatment. Infection. Drugs. Many different • Alpha- • Alcohol • • • • Myopathy may occur right after starting a medication or may occur after taking a drug for months or years. Sometimes it is caused by an interaction between two different medications. Severe myositis caused by medications is rare. Injury. Vigorous Rhabdomyolysis . Rhabdomyolysis occurs when muscles break down quickly. Symptoms of Myositis The main symptom of myositis is muscle weakness. The weakness may be noticeable or may only be found with testing. Muscle pain (myalgias) may or may not be present. The weakness from myositis can lead to falls and make it difficult to get up from a chair or after a fall. Other symptoms that may be present with inflammatory conditions include: • • • Thickening of the • Difficulty swallowing • Difficulty breathing People with myositis caused by a virus usually have symptoms ...

Diagnosing any disease is a bit like solving a mystery. The physician will collect a variety of information and fit this all together to form an understanding about what is causing the patient’s symptoms. For those with myositis, this process can be challenging for a number of reasons. • Myositis diseases are rare, which means that clinicians may not be immediately aware of what to look for. • Myositis often starts out looking like a number of different autoimmune diseases. • Myositis takes a number of different forms, each of which is also very diverse. • Myositis can occur in combination with other overlapping autoimmune diseases. • Myositis symptoms are different in every patient. The first step in any diagnosis is a medical history. The doctor will ask questions about your health in general, including detailed personal and family health histories. Then he or she will want to know about your symptoms: when you first saw signs of the skin rash, what made you first notice muscle weakness, whether you did anything to treat these symptoms yourself, whether there are certain things (foods, activities, weather) that make the symptoms better or worse, whether you had an infection or other illness around the time the symptoms started. The next step will be a physical examination. The doctor will examine your skin symptoms and test your muscle strength. He or she may ask you to demonstrate activities that are difficult because of the weakness, such as walking up steps, lifting y...

What is myositis? Myositis (my-o-SY-tis) is a rare type of autoimmune disease that inflames and weakens muscle fibers. Autoimmune diseases occur when the body's own immune system attacks itself. In the case of myositis, the immune system attacks healthy muscle tissue, which results in inflammation, swelling, pain, and eventual weakness. When there is no skin involvement, it is called polymyositis. When there is skin involvement, it is called dermatomyositis. The areas of the body affected by myositis may differ from patient to patient. Most often, myositis involves the muscles in the upper arms and thighs, which can cause difficulty raising arms above the head and rising from a chair. Some people may also experience symptoms in their lungs, such as difficulty breathing, while others may have difficulty swallowing. Women are more than twice as likely to be diagnosed as men, with most patients between ages of 30 and 60 when first diagnosed. In patients younger than 20 years old, the disease is referred to as juvenile myositis and may be treated differently. Over time, myositis symptoms may continue to worsen until everyday tasks, like climbing stairs or carrying groceries, become difficult. These symptoms develop gradually and though there is no cure, treatments are available to retain muscle strength and function. It is important to work with your rheumatologist to delay myositis complications as long as possible. Depending on whether your lungs or esophagus are affected, y...

Overview Polymyositis (pol-e-my-o-SY-tis) is an uncommon inflammatory disease that causes muscle weakness affecting both sides of your body. Having this condition can make it difficult to climb stairs, rise from a seated position, lift objects or reach overhead. Polymyositis most commonly affects adults in their 30s, 40s or 50s. Women are affected more often than men. Signs and symptoms usually develop gradually, over weeks or months. Symptoms The muscle weakness associated with polymyositis involves the muscles closest to the trunk, such as those in your hips, thighs, shoulders, upper arms and neck. The weakness affects both the left and right sides of your body, and tends to gradually worsen. When to see a doctor Seek medical attention if you develop unexplained muscle weakness. Causes The exact cause of polymyositis is unknown, but the disease shares many characteristics with autoimmune disorders, in which your immune system mistakenly attacks your own body tissues. Risk factors Your risk of polymyositis is higher if you have lupus, rheumatoid arthritis, scleroderma, or Sjogren's syndrome. Complications Possible complications of polymyositis include: • Difficulty swallowing. If the muscles in your esophagus are affected, you may have problems swallowing (dysphagia), which in turn may cause weight loss and malnutrition. • Aspiration pneumonia. Difficulty swallowing may also cause you to breathe food or liquids, including saliva, into your lungs (aspiration), which can le...

Reaching an accurate diagnosis is often a long and frustrating process for myositis patients and their doctors. Myositis diseases are rare and complex, with poorly understood origins and features that may be similar to other disorders. As such, there is not a single lab test that can easily diagnose any of the forms of myositis. Is such a situation, physicians often rely on diagnostic criteria to determine a diagnosis. Diagnostic criteria are a set of signs, symptoms, and tests used to guide the care of individual patients. They are usually broad and must reflect different features of a disease in order to accurately identify as many people with the condition as possible. While it is ideal to have criteria that are validated by research evidence, at this point in time, researchers are still working to develop and validate diagnostic criteria for myositis diseases. Until this process is completed, physician usually establish a diagnosis based on their own experience of clinical signs and symptoms, available clinical tests, and knowledge about the epidemiology of their geographical area. The following diagnostic criteria have been developed based on research data in combination with expert clinical experience. These are criteria most often used as a guide to establish a specific diagnosis. Before diagnosing any form of myositis, all other myopathies must be ruled out. (also known as immune-mediated necrotizing myopathy or necrotizing autoimmune myopathy)

Manifestations include symmetric weakness, occasionally tenderness, and fibrous replacement of muscle, sometimes with atrophy, principally of the proximal limb girdle muscles. Diagnosis is by clinical findings and abnormalities on muscle tests, which may include creatine kinase test, MRI, electromyography, and muscle biopsy. Several types of myositis have pulmonary and cardiac manifestations. Treatment is with corticosteroids combined with immunosuppressants and/or IV immune globulin. The cause of autoimmune myositis seems to be an autoimmune reaction to muscle tissue in genetically susceptible people. Familial clustering occurs, and human leukocyte antigen (HLA) subtypes are associated with myositis. For example, the alleles of the 8.1 ancestral haplotype (HLA-DRB1*03-DQA1*05-DQB1*02) increase risk of polymyositis, dermatomyositis, and Overview of Interstitial Lung Disease Interstitial lung diseases are a heterogeneous group of disorders characterized by alveolar septal thickening, fibro...

Antibodies are proteins that are part of the body’s natural immune system. They help the body recognize and remove foreign material, especially bacteria and viruses that can cause infection and disease. In some cases, however, the immune system turns this protective function against the body’s own tissues. Rather than recognizing and fighting off foreign proteins, as antibodies usually do, autoantibodies recognize a person’s own proteins and start to attack them as if they were invaders. In the case of myositis, autoantibodies are directed against skeletal muscle. This is why myositis is called an autoimmune disease. It is not clear why autoantibodies appear in the blood when a person has an autoimmune disease. They may appear years before clinical symptoms of the disease appear, they are not the cause of disease, and they do not usually have a functional role in the disease. Scientists use these proteins as biomarkers, a measurable factor that indicates the presence of a disease or other process. The value of recognizing autoantibodies as biomarkers is that there is usually a close association between particular autoantibodies and a particular form of disease or set of clinical symptoms. An autoantibody can identify a subgroup of patients who have a similar prognosis and will respond similarly to a particular treatment. Autoantibody levels in the blood can also reflect disease activity, so they can help doctors tell how well a treatment is working. Myositis autoantibodies...

There are a number of blood tests the doctor may choose. The following is a list of some of these. Unless otherwise noted, all of these tests require taking a sample of blood by using a needle. Some blood tests require that you do not eat or drink, except for water, for about eight hours before the test. Because exercise can affect some test results, you might need to limit exercise for several days before the test to avoid falsely high results. Certain medications may also affect the results of these tests, so be sure to check with your doctor if you are taking any type of medications at all, including aspirin or other over-the-counter medications. Aldolase is an enzyme found especially in the liver and skeletal muscles. When the liver or muscles are damaged, the cells release their contents (including aldolase) into the bloodstream. Since muscle weakness can be caused by problems with either the nerves or the muscles, this test identifies weakness caused by muscular problems. Aldolase will not change when weakness is caused by neurological problems. Normal ranges may vary slightly based on a particular laboratory’s calibrations. There are also slight differences in normal ranges based on age and gender. Generally, however, normal adult findings are between 1.0 to 7.5 units per liter. Antinuclear Antibodies (also known as ANA) is a screening blood test to determine if you have an autoimmune disease. Antibodies are an important part of the immune system. They fight infecti...
