Abstract:
Meningitis due to group A Streptococcus is uncommon. Only a few cases have been reported in the literature. In this paper, we report a case of a 19-year-old man who presented with fever, headache, nausea, vomiting and a decrease in level of consciousness. Five days prior to admission, he had an episode of acute pharyngitis. Group A Streptococcus was isolated from both the cerebrospinal fluid and blood. He recovered without sequelae after therapy with penicillin G for 2 weeks. Physicians should be aware that group A streptococcal infection may cause meningitis.
Insights
Group A Streptococcus meningitis is rare. This case report highlights a 19-year-old man with GAS pharyngitis who developed meningitis, emphasizing the need for physician awareness of this uncommon bacterial infection.
Area of Science:
- Infectious Diseases
- Bacteriology
- Neurology
Background:
- Group A Streptococcus (GAS) is a common pathogen, typically causing pharyngitis and skin infections.
- Meningitis is an inflammation of the membranes surrounding the brain and spinal cord, most commonly caused by viruses or bacteria.
- GAS meningitis is an exceedingly rare clinical presentation, with limited documented cases in medical literature.
Observation:
- A 19-year-old male presented with symptoms indicative of central nervous system involvement, including fever, headache, nausea, vomiting, and reduced consciousness.
- The patient reported a recent history of acute pharyngitis approximately five days before admission.
- Physical examination and diagnostic tests were performed to identify the causative agent and assess the extent of infection.
Findings:
- Cerebrospinal fluid (CSF) analysis revealed the presence of Group A Streptococcus.
- Blood cultures also yielded positive results for Group A Streptococcus, confirming systemic infection.
- The patient received a 2-week course of penicillin G, a standard antibiotic treatment for streptococcal infections.
Implications:
- This case underscores the potential for Group A Streptococcus to cause invasive infections, including meningitis, even in immunocompetent individuals.
- Physicians should maintain a high index of suspicion for GAS meningitis in patients presenting with compatible symptoms, particularly following pharyngitis.
- Early diagnosis and appropriate antibiotic therapy are crucial for favorable outcomes and preventing long-term neurological sequelae from meningitis.
