[Limitations of normal eosinophilia or possible influence of nonsteroidal anti-inflammatory agents]

Statistical analysis of eosinophilia of 331 patients at the onset of hospitalisation define a logarithmic standard population of 327 patients whose eosinophilia rates stand between 0 and 810/mm3, among them 24 lies between 500 and 810, and 4 whose eosinophilia rise over 1,000/mm3. These 4 patients had transient hypereosinophilia whose etiology was defined only in 2 cases. The 24 patients with eosinophilia between 500 and 810/mm3 were significantly more frequently men, with rheumatoid disease (specially sciatica) and users of non steroidal antiinflammatory drugs (NSAID) than the general population. It suggest that NSAID may rise eosinophilia rates inside normal limits.
