Do corticosteroids improve outcome in meningitis?

    Insights

    Corticosteroids may improve outcomes for bacterial meningitis patients. This review examines their role in managing bacterial and tuberculous meningitis in children and adults, addressing a long-standing controversy.

    Area of Science:

    • Infectious Diseases
    • Neurology
    • Pharmacology

    Background:

    • Meningitis remains a significant global health threat, causing substantial mortality and long-term sequelae.
    • Despite advances in vaccination and antimicrobial therapy, bacterial meningitis has a high mortality rate (10-30%) and can lead to severe complications like hearing loss (5-40%).
    • The efficacy of adjunctive corticosteroids in treating bacterial meningitis has been a subject of ongoing debate due to their anti-inflammatory properties.

    Purpose of the Study:

    • To review the current evidence on the role of adjunctive corticosteroids in the management of bacterial and tuberculous meningitis.
    • To evaluate the impact of corticosteroid treatment on patient outcomes in both pediatric and adult populations.
    • To address the long-standing controversy surrounding the use of corticosteroids as an adjunct therapy for meningitis.

    Main Methods:

    • Systematic review of existing literature on adjunctive corticosteroid use in meningitis.
    • Analysis of studies focusing on bacterial meningitis and tuberculous meningitis.
    • Inclusion of data for both pediatric (over 1 month) and adult patients.

    Main Results:

    • Review synthesizes findings on corticosteroid efficacy and safety in meningitis treatment.
    • Evidence is evaluated regarding the anti-inflammatory effects of corticosteroids in reducing meningitis-related complications.
    • Mortality and sequelae rates in patients receiving adjunctive corticosteroids are compared to those without.

    Conclusions:

    • Adjunctive corticosteroids may offer benefits in managing bacterial and tuberculous meningitis.
    • Further research and clinical guidelines are needed to clarify the optimal role of corticosteroids in meningitis treatment.
    • The review aims to provide clarity on this controversial therapeutic approach for clinicians.

    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...

    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...

    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...

    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,...

    Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

    Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2 (COX-2),...

    Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

    Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
    ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
