Hyper IgM syndrome can have the following syndromes: [6] [11] Infection/Pneumocystis pneumonia (PCP), which is common in infants with hyper IgM syndrome, is a serious illness. [9] PCP is one of the most frequent and severe opportunistic infections in people with weakened immune systems. Hepatitis (Hepatitis C) Chronic diarrhea; Hypothyroidism ...
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.
Immunoglobulin M (IgM) is the largest of several isotypes of antibodies (also known as immunoglobulin) that are produced by vertebrates.IgM is the first antibody to appear in the response to initial exposure to an antigen; [1] [2] causing it to also be called an acute phase antibody.

IgM, pictured, is an example of a macroglobulin. Another example is alpha-2 macroglobulin. Macroglobulins are large globular proteins and are found in the blood and other body fluids. Various physiological processes, including immunity, coagulation, and chemical transport, rely on these proteins.
Rheumatoid factor (RF) is the autoantibody that was first found in rheumatoid arthritis.It is defined as an antibody against the Fc portion of IgG and different RFs can recognize different parts of the IgG-Fc. [1]
IgM nephropathy or immunoglobulin M nephropathy (IgMN) is a kind of idiopathic glomerulonephritis that is marked by IgM diffuse deposits in the glomerular mesangium. [1] IgM nephropathy was initially documented in 1978 by two separate teams of researchers.
Anti-core antibodies (anti-HBc) are the first antibodies produced by the body, first in short-term IgM (anti-HBc IgM), and subsequently in long-term IgG; while levels of IgM anti-HBc will peak around sixteen weeks after exposure and fall within about seven to eight months, [63] [64] IgG anti-HBc will remain detectable in the serum as a sign of ...
