Insights

Neisseria meningitidis serogroup C can cause purulent pericarditis and cardiac tamponade, even without meningitis. Prompt treatment with antibiotics, pericardiocentesis, and steroids led to an excellent outcome in a teenage patient.

Area of Science:

  • Infectious Diseases
  • Cardiology
  • Pediatrics

Background:

  • Purulent pericarditis is a serious infection of the pericardium.
  • Neisseria meningitidis is a known cause of bacterial meningitis and sepsis.
  • Meningococcal pericarditis typically occurs with concurrent meningitis.

Observation:

  • A 15-year-old female presented with cardiac tamponade.
  • Purulent pericarditis was diagnosed, caused by Neisseria meningitidis serogroup C.
  • The patient had no preceding or concurrent central nervous system involvement.

Findings:

  • This case represents primary meningococcal pericarditis, an unusual presentation.
  • Neisseria meningitidis serogroup C was identified as the causative agent.
  • The patient responded well to antibiotics, pericardiocentesis, and steroid therapy.

Implications:

  • Meningococcal disease can manifest atypically, presenting diagnostic challenges.
  • Early recognition of unusual presentations is crucial for timely intervention.
  • This case highlights the importance of considering Neisseria meningitidis in purulent pericarditis, even without meningitis.

Pericarditis I: Introduction

Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

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 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 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: 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...
