Abstract:
The prevalence of Streptococcus pneumoniae (S. pneumoniae) resistant to penicillin is an increasing problem with variable prevalence across the world. In Mexico, some reports inform prevalence as high as 50% of the isolations. S. penumoniae is a germ that produces a wide variety of diseases, although the most serious infections are in respiratory tract and meningitis. Most patients with the infection caused by this microorganism have a good response to the treatment. The cases with bad prognosis and those which are eventually lethal are related to host factors and microbiologic characteristics such as resistance to beta-lactam antibiotics. The aim of this paper is to inform on three cases of fulminant meningitis due to S. pneumoniae resistant to penicillin, which presented neurological focalization, acute loss of consciousness, coma, and death within the first week, in spite of treatment with cephalosporin of third and fourth generation. In all these cases, S. pneumoniae was isolated from cerebrospinal fluid. The presence of similar cases should alert the clinician to consider an early diagnosis of penicillin resistant meningitis in order to establish an appropriate antibiotic therapy, and consequently, modify the prognosis of the patients.
Insights
Penicillin-resistant Streptococcus pneumoniae causes severe meningitis, even with advanced antibiotics. Early diagnosis and appropriate therapy are crucial for improving patient outcomes in these critical infections.
Area of Science:
- Infectious Diseases
- Microbiology
- Neurology
Background:
- Penicillin-resistant Streptococcus pneumoniae (S. pneumoniae) is a growing global health concern, with prevalence reaching up to 50% in some regions like Mexico.
- S. pneumoniae causes various diseases, notably severe respiratory tract infections and meningitis.
Observation:
- This paper details three cases of fulminant meningitis caused by penicillin-resistant S. pneumoniae.
- These cases exhibited rapid progression, including neurological focalization, loss of consciousness, coma, and death within one week, despite treatment with third and fourth-generation cephalosporins.
Findings:
- S. pneumoniae resistant to penicillin was isolated from the cerebrospinal fluid in all reported cases.
- Fulminant meningitis due to this resistant strain led to poor prognoses and fatalities.
Implications:
- Clinicians should be vigilant for penicillin-resistant S. pneumoniae meningitis, especially in severe or rapidly progressing cases.
- Early and accurate diagnosis is essential for selecting appropriate antibiotic therapy to potentially alter the grim prognosis associated with these infections.
