Monocytosis is an increase in the number of monocytes circulating in the blood. [1] Monocytes are white blood cells that give rise to macrophages and dendritic cells in the immune system. In humans, monocytosis occurs when there is a sustained rise in monocyte counts greater than 800/mm 3 to 1000/mm 3 .
Monocytopenia is a form of leukopenia associated with a deficiency of monocytes. It has been proposed as a measure during chemotherapy to predict neutropenia , [ 1 ] though some research indicates that it is less effective than lymphopenia .
Monocytosis present for ≥3 months and other causes of monocytosis have been ruled out; WHO defined CMML has two main subsets, CMML-1 and CMML-2. CMML-1 is diagnosed if myeloblasts, monoblasts and promonocytes are <5% of peripheral blood and <10% of bone marrow. CMML-2 is diagnosed if: Myeloblasts, monoblasts or promonocytes are 5-19% in blood, or
Leukocytosis can be subcategorized by the type of white blood cell that is increased in number. Leukocytosis in which neutrophils are elevated is neutrophilia; leukocytosis in which lymphocyte count is elevated is lymphocytosis; leukocytosis in which monocyte count is elevated is monocytosis; and leukocytosis in which eosinophil count is elevated is eosinophilia.
In those between 16 and 20 it is the cause of about 8% of sore throats. [9] About 45 out of 100,000 people develop infectious mono each year in the United States. [5] Nearly 95% of people have had an EBV infection by the time they are adults. [5] The disease occurs equally at all times of the year. [9]
Another cause is infection with Influenza A virus subtype H1N1 (and other subtypes of the Influenza A virus) and is then often associated with Monocytosis; [11] H1N1 was responsible for the Spanish flu, the 2009 flu pandemic and in 2016 for the Influenza-epidemic in Brazil. [12] The SARS disease caused lymphocytopenia. [13]
The 13 serotypes of L. monocytogenes can cause disease, but more than 90% of human isolates belong to only three serotypes: 1/2a, 1/2b, and 4b. L. monocytogenes serotype 4b strains are responsible for 33 to 35% of sporadic human cases worldwide and for all major foodborne outbreaks in Europe and North America since the 1980s. [15]
Infectious diseases Human monocytotropic ehrlichiosis [ 1 ] is a form of ehrlichiosis associated with Ehrlichia chaffeensis . [ 2 ] This bacterium is an obligate intracellular pathogen affecting monocytes and macrophages .
