Chronic inflammation In acute inflammation, if the injurious agent persists then chronic inflammation will ensue. This process, marked by inflammation lasting many days, months or even years, may lead to the formation of a chronic wound. Chronic inflammation is characterised by the dominating presence of macrophages in the injured tissue.
Acute pericarditis is more common than chronic pericarditis, and can occur as a complication of infections, immunologic conditions, or even as a result of a heart attack (myocardial infarction), as Dressler's syndrome. Chronic pericarditis however is less common, a form of which is constrictive pericarditis. The following is the clinical ...

Chronic systemic inflammation 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 ...
In immunology, systemic inflammatory response syndrome (SIRS) is an inflammatory state affecting the whole body. [1] It is the body's response to an infectious or noninfectious insult . Although the definition of SIRS refers to it as an "inflammatory" response, it actually has pro- and anti-inflammatory components.
Neuroinflammation is widely regarded as chronic, as opposed to acute, inflammation of the central nervous system. [5] Acute inflammation usually follows injury to the central nervous system immediately, and is characterized by inflammatory molecules, endothelial cell activation, platelet deposition, and tissue edema.

Chronic wounds mostly affect people over the age of 60. [14] The incidence is 0.78% of the population and the prevalence ranges from 0.18 to 0.32%. [18] As the population ages, the number of chronic wounds is expected to rise. [30] Ulcers that heal within 12 weeks are usually classified as acute, and longer-lasting ones as chronic.
Myelitis has an extensive differential diagnosis. The type of onset (acute versus subacute/chronic) along with associated symptoms such as the presence of pain, constitutional symptoms that encompass fever, malaise, weight loss or a cutaneous rash may help identify the cause of myelitis. In order to establish a diagnosis of myelitis, one has to ...
