Abstract
To describe the characteristics of adult invasive H. influenzae disease, 34 patients diagnosed at a single tertiary center between 2004 and 2017 were analyzed in a retrospective case series study. The annual estimated incidence was 0.1 cases/100.000 inhabitants. Dominant source of infection was pneumonia accompanied by sepsis (62%) and caused by nontypeable strains (74%) with low ampicillin resistance (14%). Survival (94%) and complication rates were high (35%). Main empirical treatments were ceftriaxone or levofloxacine.
