Overview
Epidemiology and Demographics
Incidence and prevalence
- The prevalence of ICEP remains unknown.
- The incidence of chronic eosinophilic pneumonia in an Icelandic registry was 0.23 cases/100,000 population per year between 1990 and 2004. [3] In registries of interstitial lung disease in Europe, chronic eosinophilic pneumonia accounted for 0 to 2500 per 100,000 of cases of interstitial lung disease. [4].
- ICEP has been reported to contribute to 0 to 2500 per 100,000 of cases included in different registries of interstitial lung diseases. [1].
- One third to one half of the ICEP patients have a history of asthma [7-12] and less than 10% are active smokers [2,3,7].
- It has recently been reported that ICEP may be primed by radiation therapy for breast cancer. [13].
Age
- Patients of all age groups may develop ICEP but is extremely rare in childhood. [2-5]
Race
- There is no racial predilection to ICEP.
Sex
- Women are more commonly affected by ICEP than men. The women to men ratio is approximately 2 to 1. [2,3,6,7].
