Arteritis is the inflammation of the walls of arteries, usually as a result of infection or auto-immune response. Arteritis is a complex disorder that is still not entirely understood. Arteritis may be distinguished by its different types, based on the organ systems that are affected by the disease.〔 A complication of arteritis is thrombosis, which can be fatal. Arteritis and phlebitis are forms of vasculitis. ==Types== Arteritis may be primary, or secondary to some other disease process. The primary types are given in the table below:. An example of a secondary arteritis is arteritis caused by infection with the fungal pathogen ''Candida albicans''. Giant Cell Arteritis Giant cell arteritis contain two different types of arteritides that are almost indistinguishable from one another.〔 Giant cell arteritis includes two types; these are temporal arteritis and Takayasu arteritis. Both types contain an occupancy of medium and larger size arteries which are categorized based on the infiltration of the giant cells.〔 Takayasu Arteritis This type of arteritis is most common in females, with a median age of 25 years. Takayasu arteritis is more common in women of Asian descent that are in their reproductive years.〔 However, over the past decades, the incidence of Takayasu arteritis patients in Africa, Europe, and North America has been increasing.〔 Takayasu arteritis is an inflammatory disease that mainly affects the larger vessels such as the aorta and its surrounding branches.〔 Research focused on Takayasu arteritis in the western parts of the world remains limited. An estimation suggests that, each year, the number of cases per million people is 2.6. Temporal Arteritis Temporal arteritis, the second type of giant cell arteritis, is also a chronic, inflammatory disease involving mid- to large-sized arteries. Temporal arteritis has a higher incidence in people of Scandinavian descent.〔 However, the incidence rate differs based on population, region and races.〔 Temporal arteritis is not uncommon in North America.〔 The incidence rate is around 0.017% for individuals over 50 years of age.〔 Symptoms of temporal arteritis are classified as specific and non-specific.〔 Non-specific symptoms:〔 * Headache * Low grade fever * Sweating * Anorexia (loss of appetite) * Weight loss * General malaise Specific symptoms:〔 * Claudication of the jaw * Engorged, tender vessels Specific symptoms usually develop in the advanced stages of temporal arteritis.〔 Polyarteritis nodosa unknown machanism,can cause testiscular pain.Often associated with aneurysms and Hepatitis B 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「arteritis」の詳細全文を読む スポンサード リンク
