Haemophilus Influenzae Pneumonia in Adults

Retrospective Hospital Study of Haemophilus Influenzae Pneumonia in Adults: Relapse and Severity

• Status: Completed
• Phase: —
• Study type: Observational
• Enrollment: 203 (actual)
• Sponsor: Assistance Publique - Hôpitaux de Paris · Academic / Other
• Sex: All
• Age: 18 Years
• Healthy volunteers: Not accepted

Summary

Haemophilus influenzae is a Gram-negative coccobacillus capable of colonizing and infecting the human respiratory tract. In the adult population, patients with an abnormality of their mucociliary epithelium and a deficiency in innate or adaptive immunity are particularly exposed. The Infectious and Tropical Diseases department of Necker-Enfants Malades hospital has noted a recent increase in the number of cases of respiratory infections due to H. influenzae, with a high frequency of early relapses and recurrences despite appropriate treatment. The research focuses on lower respiratory infections (pneumonia) caused by Haemophilus influenzae in adults, excluding pneumonia acquired under mechanical ventilation linked to Haemophilus influenzae in patients in 13 AP-HP hospitals during 12 months, from 09/01/2022 to 08/31/2023.

The main objective of the study is to identify factors associated with relapse in hospitalized adult Haemophilus influenzae pneumonia.
