Primary amoebic meningoencephalitis

Insights

Primary amoebic meningoencephalitis (PAM) is a rare and fatal brain infection. This report details the third UK case in an 11-year-old girl infected by Naegleria fowleri after swimming in a hot spring pool.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Parasitology

Background:

  • Primary amoebic meningoencephalitis (PAM) is a rare and devastating infection of the central nervous system.
  • The causative agent, Naegleria fowleri, is a free-living amoeba found in warm freshwater environments.
  • This report documents the third UK case of PAM, highlighting its continued presence and threat.

Observation:

  • An 11-year-old girl presented with symptoms consistent with PAM.
  • The patient had a history of swimming in a pool supplied by hot spring water.
  • Naegleria fowleri was identified in the water source, confirming the likely route of infection.

Findings:

  • The case represents the third documented instance of PAM in the United Kingdom.
  • The infection was linked to exposure to a recreational water source contaminated with Naegleria fowleri.
  • The clinical course underscores the aggressive nature of this amoebic encephalitis.

Implications:

  • Early diagnosis and treatment are critical for any chance of survival in PAM cases.
  • Amphotericin B is suggested as a potential therapeutic agent, though its efficacy in PAM remains challenging.
  • Public health awareness regarding safe water practices in warm environments is crucial to prevent Naegleria fowleri infections.
