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. [2]
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]
Special forms of granulomatous mastitis occur as complication of diabetes. Some cases are due to silicone injection (Silicone-induced granulomatous inflammation) or other foreign body reactions. [2] [3] Idiopathic granulomatous mastitis (IGM) is defined as granulomatous mastitis without any other attributable cause such as those above mentioned.
Eosinophilic granulomatosis with polyangiitis consists of three stages, but not all patients develop all three stages or progress from one stage to the next in the same order; [7] whereas some patients may develop severe or life-threatening complications such as gastrointestinal involvement and heart disease, some patients are only mildly affected, e.g. with skin lesions and nasal polyps. [8]
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 ...
Parkinson’s disease is a neurodegenerative disorder caused by the death of dopamine-producing neurons. To address this dopamine deficiency, clinicians currently prescribe L-DOPA, a precursor to ...
Recurrent bacterial and fungal infections and chronic inflammation of the gut and lungs are seen in chronic granulomatous disease (CGD) as well. CGD is caused by a decreased production of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase by neutrophils .
Rhinoscleroma, is a chronic granulomatous bacterial disease of the nose that can sometimes infect the upper respiratory tract. [1] It most commonly affects the nasal cavity—the nose is involved in 95–100 per cent of cases—however, it can also affect the nasopharynx, larynx, trachea, and bronchi. Slightly more females than males are ...
