The primary cause triggers an uncontrolled inflammatory response. [citation needed] Sepsis is the most common cause of multiple organ dysfunction syndrome and may result in septic shock. In the absence of infection, a sepsis-like disorder is termed systemic inflammatory response syndrome (SIRS). Both SIRS and sepsis could ultimately progress to ...

Despite marked systemic inflammation, the erythrocyte sedimentation rate (ESR) is paradoxically depressed, caused by low fibrinogen levels. The low ESR helps to distinguish the disorder from a flare of the underlying rheumatic disorder, in which case the ESR is usually elevated. A bone marrow biopsy or aspirate usually shows hemophagocytosis.
These inflammatory cytokines cannot be cleared and inflammatory mediators cause fever, cytopenias, coagulopathy, and central nervous system inflammation, which can progress to sepsis-like pathophysiology, shock, and death. The progression of macrophage activation in the context of rheumatic diseases is historically called MAS, and in the ...
Three types of Griscelli syndrome are recognised: type 1 has neurologic symptoms and mutations in MYO5A. Prognosis depends on the severity of neurologic manifestations. Type 2 has mutations in RAB27A and haemophagocytic syndrome, with abnormal T-cell and macrophage activation. This type has a grave prognosis if untreated.
In macrophages, the ability of phagocytosis is reduced and the M2 phenotype of macrophages (alternatively activated) is promoted. [13] Immunosenescence also results in increased production of some immune mediators, such as proinflammatory IL-6 [14] or IL-1. There may also be higher production of anti-inflammatory IL-10 or IL-4.

Abdominal pain, also known as a stomach ache, is a symptom associated with both non-serious and serious medical issues. Since the abdomen contains most of the body's vital organs, it can be an indicator of a wide variety of diseases.
Functional abdominal pain syndrome is a functional gastrointestinal disorder. [4] Functional gastrointestinal disorders (FGD) are common medical conditions characterized by recurrent and persistent gastrointestinal symptoms caused by improper functioning of the enteric system in the absence of any identifiable organic or structural pathology, such as ulcers, inflammation, tumors or masses.
