Objective:
To identify the most common causes of diffuse alveolar hemorrhage (DAH) and the evolution of cases during hospitalization.
Patients And Methods:
A review of cases diagnosed with DAH; the diagnoses were classified according to existing criteria and the progression of the cases was determined.
Results:
We identified 17 cases of DAH, with the leading cause being ANCA associated vasculitis (41% of cases), followed by cases secondary to drugs (18%). In 35% of the cases, there was a failure in identifying an etiology. Six patients died (35%), the only factor associated with mortality was male gender 5/6 vs 3/11, p=0.05.
Conclusions:
The most frequent cause of alveolar hemorrhage was ANCA associated vasculitis. The mortality in DAH is about 35%, males seem to have a worse prognosis.
