A amoebic liver abscess is a type of liver abscess caused by amebiasis. [1] ... Drainage of the abscess is the mainstay treatment. [3] Research
A large pyogenic liver abscess presumed to be the result of appendicitis. There are several major forms of liver abscess, classified by cause: [3] Pyogenic liver abscess, which is most often polymicrobial, accounts for 80% of hepatic abscess cases in the United States. Amoebic liver abscess due to Entamoeba histolytica accounts for 10% of cases ...
Pulmonary amoebiasis can occur from liver lesions by spread through the blood or by perforation of pleural cavity and lung. It can cause lung abscess, pulmono pleural fistula, empyema lung and broncho pleural fistula. It can also reach the brain through blood vessels and cause amoebic brain abscess and amoebic meningoencephalitis.
For amebic liver abscess: Metronidazole 400 mg three times a day for 10 days; Tinidazole 2g once a day for 6 days is an alternative to metronidazole; Diloxanide furoate 500 mg three times a day for 10 days (or one of the other lumenal amebicides above) must always be given afterwards
A 1979 study of 27 patients treated with dehydroemetine and various other drugs suggested all drug combinations were successful at treating amoebic liver abscesses. [5] A 1986 in vitro study compared the effects of dehydroemetine, metronidazole, ornidazole, and secnidazole on Entamoeba histolytica. Metronidazole was found to be most effective ...
In the liver a similar pathological sequence ensues, leading to amebic liver abscesses. The trophozoites can also end up in other organs, sometimes via the bloodstream, sometimes via liver abscess rupture or fistulas. Similarly, when the trophozoites travel to the brain, they can cause amoebic brain abscesses. [26]
In treatment of amoebic liver abscess, chloroquine may be used instead of or in addition to other medications in the event of failure of improvement with metronidazole or another nitroimidazole within five days or intolerance to metronidazole or a nitroimidazole.
Symptoms can progress to ameboma, fulminant colitis, toxic megacolon, colonic ulcers, leading to perforation, and abscesses in vital organs like liver, lung, and brain. Amoebiasis can be treated with the administration of anti-amoebic compounds, this often includes the use of Metronidazole , Ornidazole , Chloroquine , Secnidazole , Nitazoxanide ...
