[Phlegmona ("cellulitis") and Haemophilus influenzae meningitis]
Abstract:
Soft tissue inflammation is a rare manifestation of H. influenzae infection. It is known in the anglo-american literature as "cellulitis". Usually there is concomitant bacteremia or septicemia. The combination of cellulitis and meningitis is rare and not well known in German pediatric literature. Three children with facial cellulitis together with H. influenzae meningitis are described. In comparison to the literature some unusual observations were made: Early appearance of cellulitis at the age of six weeks in two infants, cellulitis of the lower extremities at the same time in one, and biphasic course with cellulitis and meningitis secondary to mastoiditis in another infant.
Insights
Haemophilus influenzae (H. influenzae) can cause rare soft tissue inflammation like cellulitis, sometimes alongside meningitis. This study details three pediatric cases, noting unusual presentations such as early onset and lower extremity involvement.
Area of Science:
- Pediatric Infectious Diseases
- Bacteriology
- Clinical Medicine
Background:
- Soft tissue inflammation, known as cellulitis in Anglo-American literature, is a rare manifestation of Haemophilus influenzae (H. influenzae) infection.
- Concomitant bacteremia or septicemia often accompanies H. influenzae cellulitis.
- The simultaneous occurrence of cellulitis and meningitis due to H. influenzae is infrequently documented in German pediatric literature.
Observation:
- This report describes three pediatric cases presenting with facial cellulitis and H. influenzae meningitis.
- Unusual observations included early cellulitis onset at six weeks in two infants.
- One case featured cellulitis of the lower extremities concurrently with meningitis, and another showed a biphasic course involving meningitis secondary to mastoiditis.
Findings:
- H. influenzae can present with a rare combination of cellulitis and meningitis in children.
- The study highlights variations from typical presentations, including early-onset and lower extremity cellulitis.
- A biphasic disease course, with meningitis developing after mastoiditis, was observed in one patient.
Implications:
- This case series expands the understanding of H. influenzae's clinical spectrum in pediatric patients.
- It emphasizes the need for awareness of unusual presentations of H. influenzae infections, particularly the cellulitis-meningitis combination.
- The findings may inform diagnostic and treatment strategies for H. influenzae-related soft tissue infections and meningitis in infants and children.
