[Purulent meningitis in the elderly. Incidence in our area]
Abstract:
A retrospective study in patients over 65 years old with acute bacterial meningitis admitted to the internal medicine department of the "Hospital Provincial de Zamora" over the last 25 years, is presented. 43 cases (26.87%) over 65 years old were found, out of 160 cases admitted with ABM during this period. This high prevalence is partially explained because of the large elderly population in this area. The frequent atypical clinical features than can result in the diagnosis being confused with neurological pathology such as CVA (which is common at this age) is noteworthy. The most frequent etiology was meningococos (41.86%), followed by pneumococos (4.6%) and E. Coli (4.6%). We highlight the good prognosis of ABM in the elderly, early diagnosis and the right therapy necessary to achieve it.
Insights
Acute bacterial meningitis (ABM) in patients over 65 shows a high prevalence in Zamora. Early diagnosis and appropriate therapy lead to a good prognosis in this elderly population.
Area of Science:
- Geriatrics
- Infectious Diseases
- Neurology
Context:
- Retrospective analysis of 160 acute bacterial meningitis (ABM) cases over 25 years at Hospital Provincial de Zamora.
- Focus on patients aged 65 and older, identifying 43 cases (26.87%) within this demographic.
- High prevalence in the elderly attributed to the region's significant older population.
Purpose:
- To investigate the prevalence, clinical features, etiology, and prognosis of ABM in elderly patients (≥65 years).
- To highlight diagnostic challenges due to atypical presentations mimicking cerebrovascular accidents (CVA).
Summary:
- Meningococcal infections were the most common cause (41.86%), followed by pneumococcal and E. coli.
- Atypical clinical presentations in the elderly can lead to misdiagnosis, often confused with CVA.
- Despite challenges, ABM in the elderly demonstrates a favorable prognosis with early diagnosis and prompt, correct treatment.
Impact:
- Emphasizes the importance of considering ABM in elderly patients presenting with neurological symptoms.
- Underscores the need for heightened clinical suspicion and rapid diagnostic protocols for improved outcomes in geriatric meningitis cases.
- Provides valuable epidemiological data for public health strategies targeting infectious diseases in aging populations.
