Eosinophilic pneumonia is diagnosed in one of three circumstances: when a complete blood count reveals increased eosinophils and a chest X-ray or computed tomography identifies abnormalities in the lungs, when a biopsy identifies increased eosinophils in lung tissue, or when increased eosinophils are found in fluid obtained by a bronchoscopy ...
Eosinophils are white blood cells that fight infection by destroying foreign substances in the body. This increase is determined through a blood test called a complete blood count, or CBC. A result of over 500 cells/mcL (cells per microliter of blood) is considered elevated. [4] The normal range for eosinophils is less than 350 cells/mcL. [5]
Eosinophilia is a condition in which the eosinophil count in the peripheral blood exceeds 5 × 10 8 /L (500/μL). [1] Hypereosinophilia is an elevation in an individual's circulating blood eosinophil count above 1.5 × 10 9 / L (i.e. 1,500/ μL ).
Thus, it is now evident that the normal median blood eosinophil count in healthy adults is around 100 cells/μL, with counts above 400 cells/μL considered outside the normal range. Current cutoffs such as 150 or 300 cells/μL used in asthma or COPD management fall within the normal range. [29]
Hypereosinophilic syndrome is a disease characterized by a persistently elevated eosinophil count (≥ 1500 eosinophils/mm³) in the blood for at least six months without any recognizable cause, with involvement of either the heart, nervous system, or bone marrow. [5]
The number of eosinophils in the sputum samples of non-asthmatic eosinophilic bronchitis patients are similar to those of patients with asthma. In the sputum samples of those with NAEB, histamine and prostaglandin D2 is increased. This suggests that the superficial airways have significant mast cell activation and this may lead to the differing ...
