Dermatomyositis (DM) is a long-term inflammatory disorder which affects the skin and the muscles. [1] Its symptoms are generally a skin rash and worsening muscle weakness over time. [1] These may occur suddenly or develop over months. [1] Other symptoms may include weight loss, fever, lung inflammation, or light sensitivity. [1]
It can also be associated with underlying cancer. The main classes of idiopathic inflammatory myopathy are polymyositis (PM), dermatomyositis (DM) (including juvenile, amyopathic, and sine-dermatitis form), inclusion-body myositis (IBM), immune-mediated necrotising myopathy (IMNM), and focal autoimmune myositis. [1]
Weakness comes on slowly (over months to years) in an asymmetric manner and progresses steadily, leading to severe weakness and wasting of arm and leg muscles. IBM is more common in men than women. [10] Patients may become unable to perform activities of daily living and most require assistive devices within 5 to 10 years of symptom onset.
Polymyositis and the associated inflammatory myopathies have an associated increased risk of cancer. [3] The features they found associated with an increased risk of cancer were older age, age greater than 45, male sex, difficulty swallowing, death of skin cells, cutaneous vasculitis, rapid onset of myositis (<4 weeks), elevated creatine kinase, higher erythrocyte sedimentation rate and higher ...
Women conversely are at higher risk for developing autoimmune disease, but are more protected from infectious disease than men. Women have a greater number of circulating antibodies than do men, [46] which has implications for their development of autoimmune disease, as well as their increased resistance to infectious disease.
Women appear to generally mount larger inflammatory responses than men when their immune systems are triggered, increasing the risk of autoimmunity. Involvement of sex steroids is indicated by that many autoimmune diseases tend to fluctuate in accordance with hormonal changes, for example: during pregnancy, in the menstrual cycle, or when using ...
There is a bimodal age distribution in the incidence of LS in women. It occurs in females with an average age of diagnosis of 7.6 years in girls and 60 years old in women. The average age of diagnosis in boys is from 9 to 11 years old. [69] In men, the most common age of incidence is 21 to 30. [70]
Women are more commonly affected than men. Autoimmune diseases predominantly begin in adulthood, although they can start at any age. [ 1 ] The initial recognition of autoimmune diseases dates back to the early 1900s, and since then, advancements in understanding and management of these conditions have been substantial, though much more is ...
