Introduction:
Respiratory syncytial virus infection is gaining interest in the elderly due to its growing morbidity and mortality. We present a Case of respiratory syncytial virus infection presenting as diffuse alveolar hemorrhage that was highly responsive to systemic corticosteroid in an elderly patient.
Case Presentation:
An 82-year old man was admitted to the intensive care unit with worsening hypoxic respiratory failure. Chest radiograph showed non-homogeneous air space opacities. Bronchoalveolar lavage showed a finding of alveolar hemorrhage. The diagnosis of diffuse alveolar hemorrhage was made and high-dose systemic corticosteroid was given. However, concomitant respiratory syncytial virus infection was later confirmed. Therefore, ribavirin and human immunoglobulin were added. During the course of his treatment, the steroid was stopped and restarted. Interestingly, the clinical course was highly responsive to systemic corticosteroid.
Conclusion:
It appears that diffuse alveolar hemorrhage in this patient may have been due to an immunological process caused by respiratory syncytial virus. Therefore, corticosteroid therapy was highly effective in improving the patient's hemoptysis and hypoxic respiratory failure. We suggest that further studies are required on the use of steroid in this subset of patients with respiratory syncytial virus lower respiratory tract infection.
