Vasculitis is a group of disorders that destroy blood vessels by inflammation. [2] Both arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis. [3] Vasculitis is primarily caused by leukocyte migration and resultant damage.
It can also show the blood flow within the blood vessels. [4] Ultrasonography is a popular first-line investigation for diagnosis because it is relatively quick, cheap, noninvasive, and does not expose patients to radiation. [4] It is also used for long-term monitoring of disease progression in Takayasu arteritis.
Cerebral vasculitis (sometimes the word angiitis is used instead of "vasculitis") is vasculitis (inflammation of the blood vessel wall) involving the brain and occasionally the spinal cord. [1] It affects all of the vessels: very small blood vessels ( capillaries ), medium-size blood vessels ( arterioles and venules ), or large blood vessels ...
Neutrophils migrate from blood vessels to the infected tissue via chemotaxis, where they remove pathogens through phagocytosis and degranulation Inflammation is a process by which the body's white blood cells and substances they produce protect us from infection with foreign organisms, such as bacteria and viruses. The (phagocytes) white blood ...
Inflammatory cells and red blood cells. Acute-phase proteins (APPs) are a class of proteins whose concentrations in blood plasma either increase (positive acute-phase proteins) or decrease (negative acute-phase proteins) in response to inflammation. This response is called the acute-phase reaction (also called acute-phase response).
Chronic systemic inflammation (SI) is the result of release of pro-inflammatory cytokines from immune-related cells and the chronic activation of the innate immune system.It can contribute to the development or progression of certain conditions such as cardiovascular disease, cancer, diabetes mellitus, chronic kidney disease, non-alcoholic fatty liver disease, autoimmune and neurodegenerative ...
Inflammation plays a major role in arteriosclerosis development, and consequently it is a major contributor in large arteries stiffening. [2] Increased arterial stiffness is associated with an increased risk of cardiovascular events such as myocardial infarction , hypertension , heart failure , and stroke , two of the leading causes of death in ...
Cutaneous small-vessel vasculitis (CSVV) is inflammation of small blood vessels, usually accompanied by small lumps beneath the skin. [1]: 831 [2] The condition is also known as hypersensitivity vasculitis, cutaneous leukocytoclastic vasculitis, hypersensitivity angiitis, cutaneous leukocytoclastic angiitis, cutaneous necrotizing vasculitis and cutaneous necrotizing venulitis, [3]
