Summary
This study analyzed 200 amebic liver abscess cases, finding it most common in middle-aged men. Metronidazole and chloroquine were effective treatments, with ultrasonography being a key diagnostic tool.
Area of Science:
- Hepatology
- Infectious Diseases
- Medical Diagnostics
Background:
- Amebic liver abscess (ALA) is a significant complication of Entamoeba histolytica infection.
- ALA represents a notable cause of morbidity and mortality, particularly in endemic regions.
Purpose of the Study:
- To retrospectively analyze clinical features, diagnostic methods, treatment outcomes, and complications of amebic liver abscess.
- To evaluate the efficacy of common therapeutic agents and diagnostic modalities for ALA.
Main Methods:
- Retrospective analysis of 200 ALA cases diagnosed between 1989 and 1991.
- Review of clinical presentations, laboratory findings, imaging results, treatment protocols, and patient responses.
Main Results:
- ALA accounted for 0.6% of hospital admissions, predominantly affecting males (13:1 ratio) aged 40-50 years.
- Hepatomegaly (94%) and abdominal pain (92%) were the most frequent symptoms; ultrasonography was the primary diagnostic aid.
- Single right lobe abscesses (>4 cm) were common (81.5%); metronidazole and chloroquine showed high efficacy, with aspiration in 35.5% of cases.
Conclusions:
- Amebic liver abscess is a significant clinical entity with distinct demographic and clinical profiles.
- Effective management relies on prompt diagnosis via imaging and appropriate antimicrobial therapy, with metronidazole and chloroquine being effective.
- While generally responsive to medical management, potential complications like pleural effusion and pneumonia necessitate vigilant monitoring.
