Amebic liver abscess, common in immigrants, presents with fever and pain. Oral metronidazole effectively treats most cases, reducing the need for abscess aspiration.

Area of Science:

  • Infectious Diseases
  • Hepatology
  • Medical Parasitology

Background:

  • Amebic liver abscess (ALA) is a growing concern in the United States, particularly in Western regions.
  • Increased immigration from endemic areas contributes to the rising incidence of ALA.

Purpose of the Study:

  • To review the clinical presentation, disease course, and treatment outcomes of patients with amebic liver abscess.
  • To compare current findings with previous studies to identify any changes in management.

Main Methods:

  • Retrospective review of 50 patients diagnosed with amebic liver abscess.
  • Analysis of patient demographics, clinical symptoms, laboratory findings, diagnostic imaging, and treatment responses.
  • Evaluation of serologic testing (indirect hemagglutinin antibody) for diagnostic accuracy.

Main Results:

  • The typical patient profile includes immigrant Hispanic males aged 20-40 presenting with fever, right upper quadrant pain, leukocytosis, and abnormal liver enzymes.
  • Hepatic imaging studies revealed characteristic defects.
  • Indirect hemagglutinin antibody testing demonstrated high sensitivity for diagnosis.
  • Most patients achieved rapid and complete recovery with oral metronidazole therapy.

Conclusions:

  • The clinical presentation and management of amebic liver abscess have remained consistent over time.
  • Oral metronidazole is a highly effective treatment for amebic liver abscess.
  • There is a decreasing trend in the necessity of abscess aspiration for diagnosis.
