Insights

Acanthamoeba rhinorrhea, a rare infection, was successfully treated in a COVID-19 survivor using a combination therapy. This case highlights potential contributing factors and effective treatment strategies for central nervous system Acanthamoeba infections.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Ophthalmology

Background:

  • Acanthamoeba infections, particularly those affecting the central nervous system (CNS), are rare but serious conditions.
  • There is a lack of standardized treatment protocols for amoebic meningoencephalitis, necessitating case-specific management strategies.
  • Recent recovery from COVID-19, steroid therapy, and diabetes mellitus can compromise immunity, increasing susceptibility to opportunistic infections.

Observation:

  • A 32-year-old female patient presented with Acanthamoeba rhinorrhea following a recent COVID-19 infection.
  • The patient had a history of diabetes mellitus and had undergone steroid therapy, indicating a potentially immunocompromised state.
  • The tertiary care institute in India managed the case without a pre-established protocol for this specific condition.

Findings:

  • Successful management of Acanthamoeba rhinorrhea was achieved using a combination therapy of amphotericin B and miltefosine.
  • Both amphotericin B and miltefosine possess trophicidal and cysticidal activities, crucial for eradicating Acanthamoeba.
  • The patient's recovery suggests the efficacy of this combined therapeutic approach in CNS Acanthamoeba infections.

Implications:

  • This case demonstrates a viable treatment option for CNS Acanthamoeba infections in immunocompromised individuals, including post-COVID-19 patients.
  • Identifying contributing factors like COVID-19, steroid use, and diabetes is vital for risk assessment and prevention.
  • Further research into standardized treatment protocols for Acanthamoeba infections affecting the CNS is warranted.
