Introduction:
Chronic meningococcemia is a rare clinical form of invasive Neisseria meningitidis infection. We report 2 cases.
Observations:
A 39 year-old man and a 42 year-old woman had developed a widespread, fleeting and painful maculopapular cutaneous eruption over the past few weeks, associated with intermittent fever and inflammatory arthralgia. In both cases blood cultures isolated a serogroup B meningococcus that confirmed the diagnosis. Cutaneous histology revealed a non-specific image of leukocytoclastic vasculitis. Treatment with beta lactamin antibiotics was successful after respectively 3 weeks and 12 days.
Discussion:
This septicemia is characterized by the clinical triad of cutaneous eruption, fever and arthralgia. It must not be mistaken for connectivitis because inappropriate corticosteroid prescription may provoke severe complications. Confirmation of the diagnosis is provided by the blood cultures, which should be repeated. In the case of strong clinical suspicion, the rapid improvement with antibiotics confirms the diagnosis.
Insights
Chronic meningococcemia, a rare Neisseria meningitidis infection, presents with a rash, fever, and joint pain. Prompt antibiotic treatment is effective and confirms the diagnosis.
Area of Science:
- Infectious Diseases
- Microbiology
- Dermatology
Background:
- Chronic meningococcemia is an uncommon manifestation of invasive Neisseria meningitidis infection.
- This condition requires careful differentiation from other diseases presenting with similar symptoms.
Observation:
- Two cases are presented involving a 39-year-old male and a 42-year-old female.
- Patients exhibited a widespread, transient maculopapular rash, intermittent fever, and arthralgia.
- Leukocytoclastic vasculitis was noted on cutaneous histology.
Findings:
- Blood cultures identified serogroup B meningococcus in both patients, confirming the diagnosis.
- Treatment with beta-lactam antibiotics resulted in successful recovery.
- The clinical triad of rash, fever, and arthralgia is characteristic of this septicemia.
Implications:
- Accurate diagnosis is crucial to avoid complications from incorrect treatments like corticosteroids.
- Blood cultures are essential for confirming meningococcemia and may require repetition.
- Rapid clinical improvement following antibiotic administration supports the diagnosis of chronic meningococcemia.
