Hypergammaglobulinemia is a condition that is characterized by the increased levels of a certain immunoglobulin in the blood serum. [1] The name of the disorder refers to an excess of proteins after serum protein electrophoresis (found in the gammaglobulin region).
In approximately 51–70% of people with this disease, serum IgG4 concentrations are elevated during an acute phase. [ 1 ] [ 2 ] [ 3 ] It is a relapsing-remitting disease associated with a tendency to mass forming, tissue-destructive lesions in multiple sites, with a characteristic histopathological appearance in whichever site is involved.
The water-accessible surface area of an IgG antibody. Immunoglobulin G (IgG) is a type of antibody. Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation. [1] IgG molecules are created and released by plasma B cells. Each IgG antibody has two paratopes.
Immunoglobulin M (IgM) levels are reduced, IgA and IgE are elevated, and IgG levels can be normal, reduced, or elevated. [4] In addition to thrombocytopenia, WAS patients have abnormally small platelets (i.e. microthrombocytes) and ~30% also have elevated eosinophil counts (i.e. eosinophilia). [5]
Evidence shows that there is an association between achieving higher IgG levels and reduced infection frequency. [6] If hypogammaglobulinemia remains undetected and untreated, outcomes are generally poor, especially if chronic lung damage or bronchiectasis has occurred.
Hyper IgM syndrome is a rare primary immune deficiency disorders characterized by low or absent levels of serum IgG, IgA, IgE and normal or increased levels of serum IgM. [ 8 ] They are resulting from mutations in the pathway from B-cell activation to isotype class switching.
Almost half of all U.S. adults have elevated blood pressure (systolic pressure between 120 and 19 and diastolic pressure less than 80). ... resting your arm on a flat surface that is level with ...
IgA nephropathy (IgAN), also known as Berger's disease (/ b ɛər ˈ ʒ eɪ /) (and variations), or synpharyngitic glomerulonephritis, is a disease of the kidney (or nephropathy) and the immune system; specifically it is a form of glomerulonephritis or an inflammation of the glomeruli of the kidney.
