Dr. Liu Feng
Elevated monocytes may indicate the following conditions: 1. Infection or inflammation: Infections or inflammatory conditions may cause an increase in monocyte count, such as during the recovery phase of acute infection, infective endocarditis, malaria, kala-azar (visceral leishmaniasis), and active tuberculosis. 2. Chronic infection or inflammation: Certain chronic infections or chronic inflammatory diseases, such as tuberculosis, chronic kidney disease, and rheumatic disorders, may also lead to a prolonged increase in monocytes. 3. Autoimmune diseases: Conditions such as systemic lupus erythematosus (SLE) and rheumatoid arthritis may result in abnormal immune system activity, leading to elevated monocyte levels. 4. Hematologic disorders: Diseases such as monocytic leukemia and myelodysplastic syndromes can cause abnormal proliferation of bone marrow cells, resulting in monocytosis.
