Immunoglobulins in idiopathic thrombocytopenic purpura in childhood. 1976

A S Khalifa, and J M Lusher, and J Cejka, and W W Zuelzer

Levels of immunoglobulins G, A and M were determined in 55 children with idiopathic thrombocytopenic purpura (ITP) (32 acute, 18 chronic and 5 recurrent). Mean IgG levels tended to be low in acute ITP and returned to normal with recovery. In contrast, chronic and recurrent ITP had persistently low IgG and IgA levels. C3 complement levels in 10 cases of acute ITP were normal. Seven patients with chronic ITP had their spleens removed, and IgG and IgA levels tended to rise, while IgM levels decreased in 4 patients after the operation. Low IgA levels observed at the onset of purpura in a child might favor the diagnosis of chronic or recurrent ITP.

UI	MeSH Term	Description	Entries
D007070	Immunoglobulin A	Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions.	IgA,IgA Antibody,IgA1,IgA2,Antibody, IgA
D007074	Immunoglobulin G	The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B.

D007075	Immunoglobulin M	A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin.	Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).
