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 .
Excessive activation of neutrophils, monocytes/macrophages and dendritic cells leads to auto-inflammatory symptoms, while T cell and B cell dysfunction leads to autoimmunity. Failure of innate and/or adaptive immune cells to appropriately activate, recognize, and clear infectious agents causes immunodeficiency and vulnerability to infection.
The causes of monocytopenia include: acute infections, stress, treatment with glucocorticoids, aplastic anemia, hairy cell leukemia, acute myeloid leukemia, treatment with myelotoxic drugs, intestinal resection, and genetic syndromes, as for example MonoMAC syndrome. [3]

Usually, a person with IM has few, if any, further symptoms or problems from the latent B lymphocyte infection. However, in susceptible hosts under the appropriate environmental stressors, the virus can reactivate and cause vague physical symptoms (or may be subclinical), and during this phase, the virus can spread to others.

Rarely, drugs (antibiotics, blood pressure medication, heart medication) can cause pancytopenia. For example, the antibiotic chloramphenicol can cause pancytopenia in some individuals. [1] Rarely, pancytopenia may have other causes, such as mononucleosis or other viral diseases. Increasingly, HIV is itself a cause of pancytopenia. [2]
[4] [10] [12] Decitabine/cedazuridine (Inqovi) is a fixed-dosed combination medication for the treatment of adults with myelodysplastic syndromes (MDS) and chronic myelomonocytic leukemia (CMML) that was approved for use in the United States in July 2020. [27] Hematopoietic stem cell transplantation remains the only curative treatment for CMML ...
Monocytes can perform phagocytosis using intermediary proteins such as antibodies or complement that coat the pathogen, as well as by binding to the microbe directly via pattern recognition receptors that recognize pathogens. Monocytes are also capable of killing infected host cells via antibody-dependent cell-mediated cytotoxicity.
