Hémorragie intra-alvéolaire associée à une dengue et à une leptospirose

The intra-alveolar hemorrhage syndrome is defined by the presence of red cells in the alveolar lumen and can lead to acute respiratory failure. Among the infectious etiologies of this syndrome, leptospirosis is a common cause, whereas in dengue, the intra-alveolar hemorrhage is exceptional. We report a patient aged 46 years, with no particular history, who presented a clinical picture involving acute respiratory failure, hemoptysis, bilateral alveolar images and anemia. The intra-alveolar hemorrhage has been authenticated by bronchoalveolar lavage. The etiological showed infection by both dengue and leptospirosis.
