Cryptogenic Hemoptysis in Chronic Obstructive Pulmonary Disease: Characteristics and Outcome

Background: Hemoptysis is a common presenting symptom and cause of hospitalization in the department of respiratory diseases. In a number of patients with chronic obstructive pulmonary disease (COPD) presenting with this symptom, investigations fail to reveal a precise etiology. Little data are available regarding characteristics and outcome of COPD patients presenting with cryptogenic hemoptysis (CH). Objectives: Our study goal was to assess the functional characteristics of these subjects, the risk factors for CH and the severity of hemoptysis, as well as long-term outcome. Methods: For more than 1 year, we enrolled and followed a group of 39 consecutive COPD patients admitted to our center with CH. Results: Between 1988 and 2003, 39 patients with COPD were admitted for CH in which investigation failed to reveal an etiology. The mean age was 51.3 years. All subjects were active smokers. Twenty-one patients (54%) had at least 1 risk factor for prolonged bleeding. Patients with more severe airflow obstruction tended to have more severe bleeding. Bronchoscopy appeared as useful as a computed tomography in locating the bleeding site. Arterial embolization succeeded in controlling bleeding in all patients who underwent angiography. One patient experienced a relapse in bleeding at 2 months. One developed lung cancer after 1 year. Thirty-four patients were followed for an average of 5 years. Only 2 subjects experienced recurrent hemoptysis. None died. Conclusions: CH in patients with COPD is associated with a favorable short-and long-term outcome when managed with timely angiographic embolization. Long-term incidence of lung cancer was uncommon after an episode of CH, and recurrences of hemoptysis were rare. Copyright (C) 2009 S. Karger AG, Basel
