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. [2]
Known causes include certain medications or environmental triggers, parasitic infections, and cancer. Eosinophilic pneumonia can also occur when the immune system attacks the lungs, a disease called eosinophilic granulomatosis with polyangiitis. When a cause cannot be found, the eosinophilic pneumonia is termed "idiopathic". Idiopathic ...
High magnification photomicrograph of a lung biopsy taken showing chronic hypersensitivity pneumonitis , showing mild thickening of the walls of the small air sacs by invasion of white blood cells. A multinucleated giant cell , seen within the walls of the air sacs to the right of the picture halfway down, is an important clue to the correct ...
For most infections, the immune response of the body is enough to control and apprehend the infection within a couple days, but if the tissue and the cells can't fight off the infection, the creation of pus will begin to form in the lungs which then hardens into lung abscess or suppurative pneumonitis. [6]
A high count of CD14 + CD16 ++ monocytes is found in severe infection . [30] In the field of atherosclerosis, high numbers of the CD14 ++ CD16 + intermediate monocytes were shown to be predictive of cardiovascular events in populations at risk. [31] [32] CMML is characterized by a persistent monocyte count of > 1000/microL of blood.
Pneumonia is the most common hospital-acquired infection that causes death. [29] Before the advent of antibiotics, mortality was typically 30% in those that were hospitalized. [22] However, for those whose lung condition deteriorates within 72 hours, the problem is usually due to sepsis. [41]
Fungal pneumonia is an infection of the lungs by fungi. It can be caused by either endemic or opportunistic fungi or a combination of both. Case mortality in fungal pneumonias can be as high as 90% in immunocompromised patients, [1] [2] though immunocompetent patients generally respond well to anti-fungal therapy.
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.
