Abstract:
BACKGROUND: Eosinophilia is associated with distinctive disease processes that include helminthic parasitic infections, allergic diseases and a diversity of diseases of ill defined etiology. But the rate of persistent eosinophilia is not known in incidental eosinophilia without definite diseases such as parasite or allergic diseases. METHODS: This study included 242 middle aged man who found eosinophilia incidentally in health check up at a general hospital and followed up after 2 years. The man who didn't know eosinophilia and never treated nor worked up for eosinophilia included. We study the persistent rate of eosinophilia after a follow up of 2 years. RESULTS: In 78% of incidental eosinophilia, the number of eosinophils was less than 1000/mm3. The rate of persistent eosinophilia which incidentally founded after a follow up of 2 years is 29.8%. Higher numbers of eosinophilia, higher rate of persistent eosinophilia. Eosinophil number less than 1000/mm3 showed 23.8% persistent eosinophilia, 1000 1499/mm3 46.3%, 1500 1999/mm3 57.1%, more than 2000/mm3 80% persistent eosinophilia respectively. (P<0.05). CONCLUSION: Incidental eosinophilia less than 1000/mm3 usually normalized without intervention, so simple observation is recommended.
