Bacteraemic Haemophilus influenzae community-acquired pneumonia in non-immunocompromised adults: concerning two cases.

We report two cases of bacteraemic Haemophilus influenzae community-acquire d pneumonia occurring in non immunocompromised adults, without underlying d isease. The clinical presentation was an acute pneumonia in the first case and a bronchopneumonia in the second case. In both cases, the patients were clinically and radiologically cured after antibiotic therapy (ceftriaxone 2 g daily). Bacteremic H. influenzae pneumonia is rarely reported in health y adults. Clinically, acute pneumonia due to H. influenzae is indistinguish able from Streptococcus pneumoniae pneumonia. Although S. pneumoniae remain the first etiological agent of bacterial pneumonia, empirical therapy with a third-generation cephalosporin seems reasonable in case of severe acute lobar pneumonia.
