Chronic granulomatous disease (CGD), also known as Bridges–Good syndrome, chronic granulomatous disorder, and Quie syndrome, [1] is a diverse group of hereditary diseases in which certain cells of the immune system have difficulty forming the reactive oxygen compounds (most importantly the superoxide radical due to defective phagocyte NADPH oxidase) used to kill certain ingested pathogens.

Derived from the Latin word meaning "sequel", it is used in the medical field to mean a complication or condition following a prior illness or disease. [4] A typical sequela is a chronic complication of an acute condition—in other words, a long-term effect of a temporary disease or injury—which follows immediately from the condition ...
Leishmaniases are a group of human diseases caused by Leishmania genus and transmitted by a sandfly bite can lead to granulomatous inflammation [14] in skin (cutaneous form of the disease) and liver (visceral form), with research suggesting effective granuloma formation to be desirable in the resolution of the disease. [15]
In 2012, a research paper showed that when activated CD4+ T cells and monocytes are in close contact, interaction of CD40-CD40L between these two cells and subsequent IFNγ secretion by the T cells causes upregulation and secretion of fusion-related molecule DC-STAMP (dendritic cell-specific transmembrane protein) by the monocytes, which results in LGC formation.
Neutrophil oxidative burst test (or chronic granulomatous disease (CGD) test) is a measure of neutrophil oxidation and is a useful assay in the diagnosis of chronic granulomatous disease and is also a useful means to determine the overall metabolic integrity of phagocytosing neutrophils. The NADPH oxidase enzyme is missing in CGD. From total ...
However, chronic granulomatous disease leads to inadequate H 2 O 2 production, while myeloperoxidase deficiency is characterized by a lack of myeloperoxidase to interact with present H 2 O 2. [ 1 ] [ 2 ] [ 3 ] [ 7 ] Testing with NADPH oxidase-specific assays can lead to positive results for chronic granulomatous disease and negative results for ...
Absence of the XK protein is an X-linked disease. [3] Mutational variants result in McLeod syndrome either with or without neuroacanthocytosis: the gene on the X chromosome for McLeod syndrome is physically close to the gene for chronic granulomatous disease. As a result, an individual with one relatively small deletion may have both diseases. [4]
The disease is commonly known as donovanosis, after the Donovan bodies seen on microscopy, which are a diagnostic sign. [ 13 ] The causative organism, Klebsiella granulomatis , was called Calymmatobacterium granulomatis , and some sources still use this classification, [ 14 ] [ 15 ] from the Greek kalymma (a hood or veil), referring to the ...
