Background:
Streptococcus pyogenes is a well-known cause of a variety of clinical infections including local symptoms such as tonsillopharyngitis, cervical lymphadenitis, otitis media, cellulites, erysipelas, as well as more severe diseases such as scarlet fever, osteomyelitis, necrotizing fasciitis, sepsis, and toxic shock syndrome. However, acute bacterial meningitis caused by this pathogen is unusual.
Objective:
We report a case of group A streptococcus (GAS) meningitis in a previously healthy woman with a dramatically rapid course and fatal outcome.
Case:
A 41-year-old previously healthy woman presented a history of fever, headache, vomiting, and sore throat of three days' duration. Neurological examination revealed diminished consciousness and neck rigidity. The cerebrospinal fluid (CSF) was turbid with 10,000 leukocytes/mm(3). Direct examination of CSF showed Gram-positive cocci in chains, and cultures yielded S. pyogenes. Blood cultures yielded growth of S. pyogenes. The patient was treated initially with ceftriaxone (4 g/day) and the control CSF examination was not changed on the third day, so vancomycin (2 g/day) was added to the treatment; however, she died on the fourth day of the treatment.
Conclusion:
S. pyogenes meningitis is uncommon and the incidence seems to be persistently low; nevertheless, clinicians should be aware that sporadic cases may occur and may have a fulminant course with a relevant neurological sequel.
Insights
Group A Streptococcus (GAS) meningitis is rare but can be rapidly fatal. This case highlights the importance of recognizing GAS as a potential cause of bacterial meningitis, even in previously healthy individuals, due to its severe and swift progression.
Area of Science:
- Infectious Diseases
- Neurology
- Microbiology
Background:
- Streptococcus pyogenes commonly causes various infections, from localized symptoms to severe systemic diseases.
- Acute bacterial meningitis due to S. pyogenes is an uncommon clinical presentation.
Observation:
- A previously healthy 41-year-old woman presented with fever, headache, vomiting, and sore throat.
- Neurological examination revealed decreased consciousness and neck rigidity, indicative of meningitis.
- Cerebrospinal fluid analysis showed Gram-positive cocci in chains, with S. pyogenes identified in both CSF and blood cultures.
Findings:
- The patient received initial treatment with ceftriaxone, followed by the addition of vancomycin due to lack of improvement.
- Despite aggressive treatment, the patient experienced a rapid clinical decline.
- The case resulted in a fatal outcome on the fourth day of treatment.
Implications:
- This case underscores that S. pyogenes meningitis, though rare, can occur and present with a fulminant course.
- Clinicians must maintain a high index of suspicion for S. pyogenes in cases of bacterial meningitis, particularly when symptoms progress rapidly.
- Prompt recognition and appropriate antimicrobial therapy are crucial, although outcomes can still be severe.
