Muscle fibres are destroyed after a period of inflammation, affecting the functionality of muscle tissue, and eventually leading to fatigue and muscle weakness. Due to the general maintenance program, there is a low level of these proteins in the blood all the time. Immunoglobulin therapy to stop the immune system from attacking the muscles is required in very rare cases. An MRI can be used to detect this pattern of muscle swelling, which is a sign of myositis. The levels of these proteins go up when myositis is out of control. A skin biopsy can show cellular or molecular evidence of muscle damage in patients with dermatomyositis. The role of white blood cells is to protect the body from foreign bodies or antigens such as bacteria, viruses and fungi. The rash appearing in patients with dermatomyositis can be itchy or painful, and one may also get hard lumps of tissue under their skin. The different types of myositis are polymyositis, dermatomyositis, inclusion body myositis, autoimmune necrotising myopathy, and juvenile forms of myositis. When myositis causes inflammation and weakness in both the skin and muscles, it is called dermatomyositis. When myositis causes inflammation and weakness in the muscles, it is called polymyositis. Myositis is the name for a group of rare conditions, characterised by weak, painful or aching muscles.
