Haemophilus influenzae sepsis leading to pericarditis despite antimicrobial therapy
Insights
Acute purulent pericarditis can manifest during Haemophilus influenzae type b (Hib) infection treatment. Physicians should remain vigilant for this complication, even after therapy begins.
Area of Science:
- Pediatrics
- Infectious Diseases
- Cardiology
Background:
- Haemophilus influenzae type b (Hib) is a significant cause of invasive bacterial infections in children.
- Acute purulent pericarditis is a rare but serious complication of systemic bacterial infections.
Observation:
- Two pediatric cases of acute purulent pericarditis during systemic Hib infection are presented.
- Pericarditis developed despite appropriate antibiotic treatment for bacteremia.
Findings:
- Systemic Haemophilus influenzae type b infections can lead to acute purulent pericarditis.
- This complication may emerge days after initiating antibiotic therapy for bacteremia.
Implications:
- Clinicians must consider pericarditis in the differential diagnosis of children with systemic Hib infections.
- Early recognition and management of pericarditis are crucial for favorable outcomes.
- This highlights the importance of ongoing monitoring for secondary complications during antibiotic treatment.
Abstract:
Acute purulent pericarditis is a well-recognized, though infrequently seen, manifestation of systemic Haemophilus influenzae type b disease. We recently studied two pediatric patients who developed signs of this septic complication during appropriate antibiotic treatment for bacteremia. These case reports should alert physicians to the possibility that pericarditis may become clinically evident in patients with systemic H. influenzae infections many days after initiation of appropriate therapy. The pathophysiology, diagnostic modalities and therapy are briefly reviewed.
