What is the most common cause of monocytosis?

Common infections causing monocytosis include tuberculosis, subacute bacterial endocarditis, syphilis, protozoal or rickettsial disease. Common autoimmune diseases in the differential include SLE, rheumatoid arthritis, sarcoidosis, and inflammatory bowel disease.

What are the causes of monocytosis?

Persistent causes: A diverse group of subacute or chronic infections have been associated with monocytosis. These include syphilis [23], brucellosis [24], malaria [25], tuberculosis [26], visceral leishmaniasis [27], and rickettsial infection[28].

What causes Neutrophilia and monocytosis?

Monocytosis and neutrophilia are frequent events in atherosclerosis. These phenomena arise from the increased proliferation of hematopoietic stem and multipotential progenitor cells (HSPCs) and HSPC mobilization from the bone marrow to other immune organs and circulation.

What causes Monocytopenia?

Monocytopenia is a form of leukocytopenia associated with a deficiency of monocytes. The major causes of this condition include use of myelotoxic drugs, acute infectious stress, aplastic anemia, hairy cell leukemia and myeloid leukemia.

What are the symptoms of Monocytosis?

Common symptoms reported by people with monocytosis

1 a monocytosis patient reports severe fatigue (33%)
1 a monocytosis patient reports moderate fatigue (33%)
1 a monocytosis patient reports mild fatigue (33%)
0 monocytosis patients report no fatigue (0%)

What is leukopenia Monocytosis?

Leukocytosis and Leukopenia Monocytosis is defined by an absolute monocyte count of greater than 500/µL and usually occurs in the setting of chronic inflammation resulting from infections like tuberculosis, syphilis, or subacute bacterial endocarditis, autoimmune or granulomatous disease, and sarcoidosis.

How is Monocytopenia treated?

Monocytopenia is a reduction in blood monocyte count to < 500/mcL (< 0.5 × 10 9/L). Risk of certain infections is increased. It is diagnosed by complete blood count with differential. Treatment with hematopoietic stem cell transplantation may be needed.

Is Monocytosis serious?

Monocytosis, and particularly a monocyte : lymphocyte ratio greater than 0.8–1.0, may indicate active progression of tuberculosis and an unfavourable prognosis. The normal ratio of 0.3 or less is restored when the healing process is complete.

What diseases have high monocytes?

Some conditions that can cause an increase in the monocytes in your blood are:

viral infections, such as infectious mononucleosis, mumps, and measles.
parasitic infections.
chronic inflammatory disease.
tuberculosis (TB), a chronic respiratory disease caused by a type of bacteria.

What is symptomatic Monocytosis?

Monocytosis is defined as a monocyte count that exceeds the upper limit of the reference range of 0.95 X 199/L (950/μL). Monocytosis is commonly caused by the following conditions: Bacterial infections: These include tuberculosis, subacute bacterial endocarditis, and brucellosis.
