Nosocomial bacterial and fungal meningitis in cancer patients
Abstract:
Five cases of nosocomial meningitis are described that occurred within 5 years in a national cancer center in neutropenic cancer patients after cytotoxic chemotherapy: one caused by the yeast Aureobasidium mansoni and four caused by bacteria (two by Enterococcus faecalis and one by Salmonella enteritis and Arcanobacterium haemolyticus. Despite the severe symptoms, all cases were cured with appropriate antimicrobial therapy.
Insights
Nosocomial meningitis in neutropenic cancer patients is rare but serious. Prompt antimicrobial therapy led to complete recovery in all five reported cases, including yeast and bacterial infections.
Area of Science:
- Infectious Diseases
- Oncology
- Microbiology
Background:
- Neutropenic cancer patients undergoing cytotoxic chemotherapy are highly susceptible to infections.
- Nosocomial meningitis, an infection of the central nervous system, poses a significant risk in immunocompromised individuals.
- Understanding the causative agents and treatment outcomes is crucial for managing these severe infections.
Observation:
- Five cases of nosocomial meningitis were identified over a 5-year period at a national cancer center.
- The affected patients were all neutropenic and had recently received cytotoxic chemotherapy.
- Infections were caused by a yeast (Aureobasidium mansoni) and bacteria (Enterococcus faecalis, Salmonella enteritis, Arcanobacterium haemolyticum).
Findings:
- Despite severe clinical presentations, all five patients with nosocomial meningitis achieved a complete cure.
- Appropriate and timely antimicrobial therapy was instrumental in the successful treatment outcomes.
- The spectrum of pathogens included both fungal and bacterial agents, highlighting the need for broad-spectrum or targeted treatment.
Implications:
- This case series underscores the importance of vigilant monitoring for meningitis in neutropenic cancer patients.
- Effective antimicrobial strategies can lead to favorable outcomes even in severe nosocomial infections.
- Further research into preventative measures and optimal treatment protocols for this vulnerable population is warranted.

01:30Pneumonia I: Introduction
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

01:24Bacterial 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...
01:18Viral 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...
01:27Cryptococcal 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,...
01:22Bacterial 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...
01:26Bacterial 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...
