[Chronic eosinophilic pneumonia or Carrington's disease].
Chronic eosinophilic pneumonia (CEP) was described by Carrington in 1969. It is twice as common in women as it is in men and is probably most common at middle age. Symptoms usually associated fever, weight loss, fatigue and dyspnoea. Extra-respiratory manifestations are rare but may involve many organs. Classical radiological findings are diffuse alveolar infiltrates, with a peripheral predominance which explains the classic description of a "negative of pulmonary edema". Peripheral blood eosinophilia is present in 90%. The inflammatory syndrome with an eosinophilic alveolitis is constant. Pulmonary function tests show a restrictive pattern with depressed DLCO and hypoxemia. In atypical cases, proof of diagnosis is supported by lung biopsies that show intra alveolar and interstitial accumulation of eosinophils in peripheral air spaces. Areas of bronchiolitis obliterans are also frequently seen. In some atypical forms of chronic eosinophilic pneumonia, other disorders have to be discussed, like bronchiolitis obliterans with an organizing pneumonia or cryptogenetic organizing pneumonia and even tuberculosis. After corticosteroid therapy, the resolution occurs very rapidly but relapses are frequent. Steroid-dependence is seen in 20 to 30% of patients.
