What are the symptoms of lupus myositis?

Some people with lupus develop myositis, an inflammation of the skeletal muscles that causes weakness and loss of strength. Lupus myositis often affects the muscles of your neck, pelvis, thighs, shoulders and upper arms; difficulty in climbing stairs and getting up from a chair are early symptoms.

Can stress trigger myositis?

For those of us with chronic autoimmune diseases, such as the idiopathic inflammatory myopathies, generally referred to as myositis, stress can be even more damaging. It has been shown that stress can diminish our immune system, cause disease, and increase inflammation.

What are the first signs of myositis?

The main symptoms are weak, painful or aching muscles. This usually gets worse, slowly over time. You may also trip or fall a lot, and be very tired after walking or standing. If you have any of these symptoms you should see a GP.

How is lupus myositis diagnosed?

Muscle and skin biopsy are often the most definitive way to diagnose myositis diseases. Small samples of muscle tissue show abnormalities in muscles, including inflammation, damage, and abnormal proteins. For those with skin symptoms, doctors often biopsy a bit of skin to examine for characteristic abnormalities.

Can you have both lupus and myositis?

Some people with these symptoms may not have lupus or myositis, but another condition entirely. Or, they could have both diseases, since they very occasionally occur with one another. Either way, an accurate diagnosis is vital for treatment.

Myositis - A Diagnostic Journey

Is myositis worse than lupus?

Abstract. Myositis is a rare but well-recognized complication of systemic lupus erythematosus (SLE). It is reputed to be milder than primary myositis in terms of morbidity and treatment response.

What is the life expectancy of lupus myositis?

The prognosis of lupus is better today than ever before. With close follow-up and treatment, 80-90% of people with lupus can expect to live a normal life span.

What can be mistaken for myositis?

Among metabolic myopathies that can mimic myositis are disorders of carbohydrate metabolism such as McArdle's disease, 6-phosphofructokinase deficiency, and Pompe's disease (adult acid maltase deficiency); disorders of lipid metabolism such as carnitine deficiency and carnitine palmitoyltransferase 2 (CPT2) deficiency; ...

Does myositis show up in blood work?

After a careful history and physical exam to document the pattern of weakness in muscles, a doctor who suspects myositis likely will order a blood test to check the level of creatine kinase (CK), an enzyme that leaks out of muscle fibers when the fibers are being damaged. In PM, the CK level is usually very high.

What triggers myositis?

Causes. Anything that causes swelling in the muscles – including injury, vigorous exercise, infection or exposure to some viruses (the common cold and flu) – can trigger myositis. Certain medications (such as statins) and illegal drugs (like cocaine) can cause myositis, too.

How do doctors test for myositis?

The diagnosis of myositis involves a complete physical exam, blood test, electromyography (a neurological test that assess the electrical activity in your muscles), and a muscle biopsy, which involves removing a small sample of muscle tissue for testing.

What part of the body does myositis affect?

Myositis can affect people of any age, including children. The main muscles to be affected are around the shoulders, hips and thighs. Having myositis can also lead to other parts of the body being affected, such as the skin, lungs or heart.

What happens if myositis is left untreated?

If left untreated, the muscle inflammation in myositis can lead to permanent muscle damage and loss of muscle mass. Myositis can be associated with problems in other organs like the joints and the lungs. In dermatomyositis, there is usually a rash or skin inflammation in addition to the muscle inflammation.

Who is most likely to get myositis?

It usually affects people older than 50. Inclusion body myositis causes muscle weakness in your extremities (your hands and your legs below your knees). It can also affect the muscles in your throat that help you swallow.

What is the best medication for myositis?

Corticosteroids, often called steroids, are used to decrease inflammation in myositis. The most commonly prescribed type is prednisone; others include: cortisone, hydrocortisone, prednisone, prednisolone, methylprednisolone, triamcinolone, dexamethasone, and betamethasone. They are sold under many brand names.

What autoimmune conditions cause myositis?

When should I suspect myositis?

When to suspect the diagnosis — The diagnosis of dermatomyositis (DM) or polymyositis (PM) should be suspected in patients who present with proximal muscle weakness. The suspicion for DM in particular should be further increased if the patient has a cutaneous eruption suggestive of DM.

Is ANA positive in myositis?

Antinuclear antibodies (ANA) are positive in up to 80% of patients with dermatomyositis and polymyositis. If the ANA test is positive, further testing for specific types of antibodies is important in increasing the suspicion for an overlap syndrome.

What is the marker for myositis?

Given these limitations, serum CK levels are generally good markers of disease activity in myositis.

What body aches do you get with lupus?

Muscle and joint pain.

You may experience pain and stiffness, with or without swelling. This affects most people with lupus. Common areas for muscle pain and swelling include the neck, thighs, shoulders, and upper arms.

How quickly does myositis progress?

Patients diagnosed with IBM progress to disability usually over a period of years. The older the age of onset is, the faster the loss of strength and mobility. By 15 years, most patients require assistance with basic daily routines, and some become wheelchair- bound or bedridden.

Is myositis a terminal illness?

While sporadic inclusion body myositis is a progressive disease, life expectancy for those with sIBM is usually the same as for those without the disease. In fact, IBM patients usually don't die from the disease, but from complications (often preventable) that are associated with it.
