Infectious mononucleosis (IM, mono), also known as glandular fever, is an infection usually caused by the Epstein–Barr virus (EBV). [2] [3] Most people are infected by the virus as children, when the disease produces few or no symptoms. [2] In young adults, the disease often results in fever, sore throat, enlarged lymph nodes in the neck, and ...
There are several forms of Epstein–Barr virus (EBV) infection. These include asymptomatic infections, the primary infection, infectious mononucleosis, and the progression of asymptomatic or primary infections to: 1) any one of various Epstein–Barr virus-associated lymphoproliferative diseases such as chronic active EBV infection, EBV+ hemophagocytic lymphohistiocytosis, Burkitt's lymphoma ...
The symptoms of ATL were different from other lymphomas known at the time. The common birthplace shared amongst most of the ATL patients was suggestive of an infectious cause, referred to as ATLV. [5] Strikingly, ATLV had the transforming activity in vitro. [6] These studies established that HTLV-1 was the causitive agent of ATL.
The mononuclear spot test or monospot test, a form of the heterophile antibody test, [1] is a rapid test for infectious mononucleosis due to Epstein–Barr virus (EBV). It is an improvement on the Paul–Bunnell test. [2] The test is specific for heterophile antibodies produced by the human immune system in response to EBV infection.
XLP is also known as Duncan disease, after 6 of 18 males in the Duncan family died of lymphoproliferative disease, including fulminant infectious mononucleosis and lymphoma. [14] It is also called "Purtilo's syndrome", after David Theodore Purtilo (1939–1992), a pioneering pathologist and immunologist at the American Army Center for Pathology ...
Adult T-cell leukemia/lymphoma (ATL or ATLL) is a rare cancer of the immune system's T-cells [1] [2] [3] caused by human T cell leukemia/lymphotropic virus type 1 (). [4] All ATL cells contain integrated HTLV-1 provirus further supporting that causal role of the virus in the cause of the neoplasm. [4]
[1] [2] The virus establishes latent infection and causes infectious mononucleosis. There is also increasingly more evidence that EBV may be a trigger of multiple sclerosis. [3] It is a dual-tropic virus, meaning that it infects two different host cell types — in this case, both B cells and epithelial cells.
Infectious mononucleosis, most commonly caused by EBV, may present as a fever of unknown origin. Other symptoms of infectious mononucleosis vary with age with middle-aged adults and the elderly more likely to have a longer duration of fever and leukopenia , and younger adults and adolescents more likely to have splenomegaly , pharyngitis and ...
