Myositis: Causes, Diagnosis, and Treatment

The inflammatory muscle disorders are a group of rare diseases marked primarily by muscle inflammation and weakness. In general, muscle inflammation is referred to as “myositis,” regardless of the cause – however, myositis is frequently used as shorthand to refer to common causes of inflammatory muscle disorders or idiopathic inflammatory myopathies (IIM). Types of myositis Different forms of myositis include: • Polymyositis • Dermatomyositis • Inclusion Body Myositis • Autoimmune Necrotizing Myopathy Causes of myositis The white blood cells of the immune system generally protect us from things in the environment, like bacteria and viruses. In myositis, the immune system mistakenly injures muscle tissue, causing muscle weakness and other related conditions. It is not clear why these conditions develop, or what sets it off for most people, though there are clues in some cases. While there is no cure for myositis, there are a variety of treatments that can help patients manage their symptoms successfully. Symptoms of myositis The most common symptom of myositis is muscle weakness. The weakness often develops slowly, and can be subtle at first. The symptoms of weakness depend on the group of muscles affected – most often, myositis affects the muscles closest to the trunk, at the shoulders and hips. The weakness in myositis is generally not associated with pain, but some muscle pain can be seen in about a third of patients. It can be hard to distinguish fatigue from weakness, ...

Myositis: Symptoms, Causes, and Treatment

Myositis is a chronic, progressive inflammation of the muscles. Some types are associated with skin rashes. Medications and exercises can help, but finding the right treatment may take trial and error. This rare disease can be difficult to diagnose, and the cause is sometimes unknown. Symptoms can appear rapidly or gradually over time. Primary symptoms may include muscle pain and soreness, fatigue, trouble swallowing, and difficulty breathing. In the United States, there are an estimated 1,600 to 3,200 new cases per year and 50,000 to 75,000 people living with myositis. Myositis can affect both children and adults. With the exception of one type of myositis, women are more likely to be affected by this disease than men. The five types of myositis are: • dermatomyositis • inclusion-body myositis • juvenile myositis • polymyositis • toxic myositis Dermatomyositis Dermatomyositis (DM) is the easiest form of myositis to diagnose due to the purple-red rashes in the shape of the Other symptoms of DM include: • scaly, dry, or rough skin • Gottron’s papules or Gottron’s sign (bumps found over the knuckles, elbows, and knees, often with a raised, scaly breakout) • trouble rising from a seated position • fatigue • weakness in the neck, hip, back, and shoulder muscles • difficulty swallowing • hoarseness in the voice • hardened lumps of calcium under the skin • muscle pain • joint inflammation • nail-bed abnormalities • weight loss • irregular heartbeat • gastrointestinal ulcers Incl...

Myalgia and Myositis: Know about Muscle Pain and Inflammation

Advertisement Myositis means the muscles are inflamed. Inflammation doesn’t always cause pain; sometimes it causes weakness. Since myalgia and myositis refer to a symptom, which is generally a body response, such as pain or inflammation, they can be linked to a wide number of disorders. Therefore, a specific diagnosis is needed to treat people with these conditions. Diseases that may cause myalgia and myositis There are a number of causes of myalgia and myositis that have been documented by medical professionals. Viruses like influenza, herpes simplex, Epstein Barr and poliomyelitis, as well as bacterial infections, including strep throat and Histoplasmosis, a fungus found in the droppings of birds and bats in humid climates that can infect human lungs, has been linked to myalgia and myositis. Additionally, there is evidence that the following could be causes of myalgia and myositis. • Immunizations • Medications (anticonvulsants, antibiotics, anticancer agents, diuretics) • Substance abuse • Poisons (snake, insect, spider bites or strychnine) • Deficiencies in vitamin C and B-complex • Deficiencies in minerals and electrolytes When it comes to myalgia, certain endocrine and metabolic disorders, including A number of autoimmune diseases have been associated with both myalgia and myositis. The most well known are Types of myalgia There are four myalgia types, and no matter which type a person suffers from it can impact quality of life. The type of myalgia depends on what ar...

Myositis Autoantibodies

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...

Dermatomyositis

Overview Dermatomyositis (dur-muh-toe-my-uh-SY-tis) is an uncommon inflammatory disease marked by muscle weakness and a distinctive skin rash. The condition can affect adults and children. In adults, dermatomyositis usually occurs in the late 40s to early 60s. In children, it most often appears between 5 and 15 years of age. Dermatomyositis affects more females than males. Symptoms The signs and symptoms of dermatomyositis can appear suddenly or develop gradually over time. The most common signs and symptoms include: • Skin changes. A violet-colored or dusky red rash develops, most commonly on your face and eyelids and on your knuckles, elbows, knees, chest and back. The rash, which can be itchy and painful, is often the first sign of dermatomyositis. • Muscle weakness. Progressive muscle weakness 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 muscle weakness or an unexplained rash. Causes The cause of dermatomyositis is unknown, but the disease has much in common with autoimmune disorders, in which your immune system mistakenly attacks your body tissues. Genetic and environmental factors also might play a role. Environmental factors could include viral infections, sun exposure, certain medications and smoking. Complications Possible complications of dermato...

Autoimmune Myositis

Autoimmune myositis is characterized by inflammatory and degenerative changes in the muscles (polymyositis, necrotizing immune-mediated myopathy) or in the skin and muscles (dermatomyositis). 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, fibroblast proliferation, collagen deposition, and, if the process remains unchecked... read more . Possible inciting events include viral myositis and underlying cancer. The association of cancer with dermatomyositis (less so with polymyositis) suggests that a tumor may incite myositis as the result of an...
