Amebic liver abscess

Amebic liver abscess is a type of liver abscess caused by the parasite Entamoeba histolytica. It is a common complication of amebiasis, a parasitic infection of the intestines.

Etiology

The causative agent of amebic liver abscess is Entamoeba histolytica, a single-celled parasite. The parasite is transmitted through the fecal-oral route, often through contaminated food or water. Once ingested, the parasite travels to the intestines, where it can cause amebiasis. In some cases, the parasite can travel to the liver and cause an abscess.

Symptoms

Symptoms of amebic liver abscess can vary, but often include fever, abdominal pain, and weight loss. In severe cases, patients may experience jaundice or hepatomegaly (enlarged liver).

Diagnosis

Diagnosis of amebic liver abscess is typically made through a combination of medical history, physical examination, and laboratory tests. Imaging studies such as ultrasound or CT scan may be used to visualize the abscess. Laboratory tests may include blood tests to check for elevated white blood cell count, liver function tests, and stool tests to identify the parasite.

Treatment

Treatment for amebic liver abscess typically involves antiparasitic drugs such as metronidazole or tinidazole, followed by a luminal agent to eliminate any remaining parasites in the intestines. In severe cases, surgical intervention may be necessary to drain the abscess.

Prevention

Prevention of amebic liver abscess involves measures to prevent amebiasis, such as practicing good hygiene, drinking safe water, and avoiding uncooked foods in areas where the parasite is common.
