Acanthamoeba Infection in a Drowning Child

Area of Science:

• Infectious Diseases
• Neurology
• Critical Care Medicine

Background:

• Acanthamoeba infection is a rare but severe complication of drowning.
• Current management strategies for Acanthamoeba infection lack established protocols and successful outcomes.
• Survival data for Acanthamoeba infection are primarily limited to individual case reports.

Observation:

• A 2-year-old boy presented with decreased consciousness and respiratory distress post-drowning.
• Diagnosis confirmed Acanthamoeba in sputum and cerebrospinal fluid, alongside Pseudomonas aeruginosa and cerebral edema/encephalitis.
• Initial treatment included ceftazidime, metronidazole, fluconazole, and rifampicin.

Findings:

• The patient exhibited improved consciousness after treatment with metronidazole, rifampicin, and fluconazole.
• Despite treatment, the patient's neurological status remained altered, indicating persistent central nervous system involvement.
• No definitive cure for Acanthamoeba infection has been established, highlighting treatment challenges.

Implications:

• This case suggests a potential benefit of combining metronidazole, rifampicin, and fluconazole in managing severe Acanthamoeba infections post-drowning.
• Further research is needed to establish effective treatment guidelines for this life-threatening condition.
• Early diagnosis and aggressive management are crucial for improving outcomes in drowning-associated Acanthamoeba infections.
