[Infectious meningitis in the adult: 3-year clinical experience]

Insights

This study analyzed 390 infectious meningitis cases from 1984-1986, finding acute bacterial meningitis and acute lymphocytic meningitis were most common. Seasonal patterns and specific pathogens like Neisseria meningitidis were identified.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Epidemiology

Context:

  • Analysis of infectious meningitis cases in an adult population.
  • Data collected from the Department of Neurology, Hospital del Rey, between 1984 and 1986.
  • Review of 390 meningitis episodes.

Purpose:

  • To establish the epidemiologic features of infectious meningitis in the local adult population.
  • To identify the incidence and characteristics of different meningitis types.
  • To compare findings with existing studies.

Summary:

  • Acute bacterial meningitis accounted for 51% of cases, acute lymphocytic meningitis for 45%, and tuberculous meningitis for 26%.
  • Bacterial meningitis peaked in winter, while lymphocytic meningitis peaked in summer (p < 0.001).
  • Neisseria meningitidis was a primary cause of bacterial meningitis (47%), and Herpesviridae of lymphocytic meningitis (14.5%).
  • Mortality rates were 8.5% for acute bacterial meningitis and 10% for tuberculous meningitis.

Impact:

  • Highlights the significant burden of infectious meningitis in the studied adult population.
  • Provides crucial data for understanding seasonal variations and causative agents.
  • Informs public health strategies and clinical management of meningitis.

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
