Muscle inflammation, or myositis, can cause significant fatigue and difficulty in sustaining physical efforts. Myositis is an autoimmune disease where the immune system attacks the body's own healthy muscle fibres, causing muscle weakness and fatigue. The condition can affect muscles all over the body and make even simple movements hard to execute. Polymyositis, dermatomyositis, and inclusion body myositis are some of the most common types of myositis, each with unique symptoms and severity. While there is no cure for myositis, treatments aim to ease symptoms and improve patients' physical activity and quality of life.

Myositis: Muscle inflammation and fatigue
Myositis is a rare condition that causes chronic muscle inflammation. It is an autoimmune disease, meaning that the body's immune system mistakenly attacks healthy muscle fibres, injuring or destroying them. This can lead to muscle weakness, pain, and fatigue. The condition can vary in severity and symptoms between individuals, with some cases being mild and others severe. While there is no cure for myositis, treatments such as medication, physical therapy, and lifestyle changes can help manage the symptoms.
The main muscles affected by myositis are typically those around the shoulders, hips, and thighs. However, the condition can also impact other parts of the body, such as the skin, lungs, or heart. In some cases, myositis can affect the muscles responsible for breathing and swallowing, making it a potentially serious condition. The two most common types of myositis are polymyositis and dermatomyositis. Polymyositis affects multiple muscles simultaneously, especially those near the centre of the body. Dermatomyositis causes similar symptoms but is also characterised by a skin rash.
Inclusion body myositis (IBM) is another form of the condition, typically affecting muscles near the ends of the arms or around the tops of the legs. This can lead to difficulty in gripping objects or cause the knee to give way, resulting in falls. IBM is more common in men and usually develops in people over the age of 50. A unique feature of IBM is the build-up of protein in the muscles, which can be challenging to detect in the early stages of the condition.
The symptoms of myositis can vary widely between individuals, and each patient's experience is unique. Some people may experience arthritis-like symptoms in their hands, lung inflammation causing coughing or shortness of breath, or skin inflammation and rashes. The weakness caused by myositis often develops slowly and can impact the ability to perform everyday tasks that require arm movement, such as washing or brushing hair.
While the exact causes of myositis are not fully understood, certain factors can trigger inflammation. These include inflammatory conditions, particularly autoimmune conditions where the body attacks its own tissues. Viral infections are the most common infectious cause, but bacteria, fungi, or other organisms can also trigger the condition. Treatment for myositis typically involves medication such as corticosteroids and immunosuppressants, as well as physical therapy to improve muscle strength and flexibility.

Polymyositis: Inflammation and fatigue
Myositis is the term used to describe muscle inflammation. It is caused by white blood cells of the immune system, which usually protect the body from infections. In people with myositis, these cells mistakenly attack healthy muscle fibres, injuring or destroying them. This affects muscle function and can lead to fatigue and weakness.
Polymyositis is a disease that causes muscles to become irritated and inflamed. It is a type of myositis, along with dermatomyositis and inclusion body myositis. Polymyositis affects skeletal muscles on both sides of the body, while dermatomyositis causes similar symptoms and a skin rash, and inclusion body myositis is characterised by progressive muscle weakness and muscle shrinking. Polymyositis can make it difficult to perform everyday tasks such as walking up stairs, lifting arms or getting out of a chair.
As inflammation caused by polymyositis gets worse, pain and weakness may affect the ankles, wrists and lower arms. It can also cause weight loss and poor nutrition if muscle weakness leads to trouble eating and swallowing. In some cases, it can lead to respiratory failure. Polymyositis can also affect the muscles involved in breathing and swallowing, as well as the skin, lungs or heart. It can cause fever, fatigue and stiffness, which can make daily tasks challenging.
There is no known cure for polymyositis, but symptoms can be managed with treatments such as anti-inflammatory medicines and immunosuppressive medicines.

Dermatomyositis: Skin inflammation and fatigue
Muscle inflammation, or myositis, can cause significant fatigue. Myositis is the term used to describe inflammation in muscles, which can be caused by white blood cells of the immune system mistakenly attacking healthy muscle fibres. This can lead to muscle weakness and fatigue.
Dermatomyositis is a rare type of myositis that causes muscle inflammation and a distinctive skin rash. It is an uncommon inflammatory disease that affects both muscles and skin. The condition can occur at any age but is most common in adults aged 50 to 70, with a higher prevalence in women. The exact cause is unknown, but it is believed to be related to the body's immune system attacking its own tissues.
The symptoms of dermatomyositis include a red, purple, or dusky-violet rash on sun-exposed skin, elbows, knees, knuckles, chest, back, and eyelids. The rash can be itchy and painful and is often the first sign of the disease. Muscle weakness is another common symptom, which can affect the ability to perform everyday tasks such as climbing stairs, brushing hair, or getting in and out of cars. Some people with dermatomyositis also experience trouble talking or swallowing.
There is currently no cure for dermatomyositis, but treatments can help manage symptoms and improve skin and muscle function. Treatment options include immunosuppressive drugs, immunoglobulin therapy, and physical therapy. In some cases, surgery may be required to remove painful or infected calcium deposits that can occur under the skin. While there is no cure, periods of symptom improvement can occur.
Dermatomyositis can also lead to complications in other organ systems, including the lungs, heart, and gastrointestinal tract. Lung disease, heart disease, and cancer have all been observed as potential consequences of the condition. It is also strongly associated with malignancy, especially in adults. Therefore, prompt medical attention and an individualised treatment plan are crucial for managing dermatomyositis.

Inclusion body myositis: Muscle weakness and fatigue
Muscle inflammation, or myositis, can lead to muscle weakness and fatigue. Myositis is caused by white blood cells of the immune system mistakenly attacking healthy muscle fibres and injuring or destroying them. This affects muscle function and can cause fatigue and weakness.
Inclusion body myositis (IBM) is a type of myositis that causes muscle weakness and degeneration in certain areas of the body, particularly the wrists and fingers, front of the thighs, and front of the legs below the knee. IBM is characterised by the presence of inclusion bodies, which are clumps of abnormal proteins within muscle cells. These inclusion bodies contribute to weakening the muscles and can be seen under a microscope. IBM usually develops after the age of 50 and is more common in men than in women.
The symptoms of IBM develop gradually and can include progressive weakness in the muscles of the hand, forearm, thigh, and lower leg. This can lead to difficulties with ordinary tasks such as gripping objects or buttoning shirts. IBM can also cause muscle atrophy (thinning and wasting of muscles) and mild muscle pain. The rate of muscle decline varies among individuals, and there is currently no effective treatment for IBM. However, a combination of medication and rehabilitation therapy can be beneficial for many patients.
IBM is one of the most common myopathies, or muscle diseases, and is estimated to affect between 5 and 9 out of every 1 million adults in the United States. It is a degenerative and inflammatory condition, with inflammatory immune cells invading the muscle tissue and surrounding the inclusion bodies. The cause of IBM is unclear, but it may be related to autoimmune reactions or genetic factors.

Anti-synthetase syndrome: Lung inflammation and fatigue
Muscle inflammation, or myositis, can be caused when white blood cells of the immune system mistakenly attack healthy muscle fibres, injuring or destroying them. This can lead to muscle weakness and fatigue. Myositis can also affect other parts of the body, such as the skin, lungs or heart.
Anti-synthetase syndrome (ASS) is an uncommon immune-mediated condition that can affect several parts of the body, including the muscles and lungs. It is an autoimmune disease, meaning it is caused by an overactive immune system. The immune system produces autoantibodies, known as anti-synthetase autoantibodies, that attack the body's own cells. While anyone can develop anti-synthetase syndrome, it is more common in women and people over 50.
ASS is characterised by myositis, interstitial lung disease (ILD), non-erosive arthritis, and less common features such as fever, Raynaud's phenomenon, and skin changes. ILD damages the tissues between the small air sacs in the lungs (alveoli) and the surrounding blood vessels. This can cause shortness of breath, dry cough, fatigue, and chest discomfort.
ASS can be diagnosed through a series of tests, including blood tests, urine tests, pulmonary function tests, CT scans, electromyography (EMG), magnetic resonance imaging (MRI), and muscle or lung biopsies. Treatment options include corticosteroids and immunosuppressive agents, which can improve patient outcomes and survival. However, there is currently no cure for ASS, and treatment focuses on managing symptoms and minimising damage.
