jeptico Assesment of validity of counterimmunoelectrophoresis and ELISA in the routine diagnosis of amoebiasis. Hodgkin’s and non-Hodgkin’s hepatic lymphoma: World J Surg ; Pyogenic and amebic liver abscess. Both techniques were used to detect amoebic antibodies in 50 control patients, 30 patients with liver abscess and 30 patients with intestinal amoebiasis.

Although extremely uncommon in the cases of acute onset, this complication leads to a life threatening emergency, causing cardiac tamponment, and it is invariably lethal [41] Figure Ultrasonography and CT scan studies can identify the large hepatic abscesses ready to rupture, requiring immediate drainage. Lancet ; suppl 1: Visconde de Souza Franco, Zip code: J Pathol ;1: To prevent relapses after the treatment with metronidazole, even in the absence of dysentery and other symptoms of enteric amebiasis, a luminal amebicide must be administered to eradicate cysts and trophozoites from the intestine.

Journal of Postgraduate Medicine Clin Microbiol Rev ; Although not yet commercially available, there has been continuous progress in this field.

An intensive pain localized over the lower rib cage on the right side, a dry cough, shortness of breath, and severe dyspnea in a patient with hepatic amebiasis, are suggestive symptoms of an initial pulmonary complication, that demands urgent chest radiographic or CT scan hptico [33]. Percutaneous drainage of consecutive abscesses: But this is possible only in a few cases.


It is often very high, continuous or intermittent and accompanied by chills, weakness and profuse perspiration. The enlargement of the liver varies with the size and the site of the lesion.

Surgical drainage by laparotomy is reserved to patients with secondary infections. Sign up for a FREE trial. A comparative study of image-guided percutaneous procedures for abscessp treatment of liver abscesses.

In contrast with the last four decades, when patients with hepatic amebiasis were systematically submitted to surgical drainage by laparotomy, medical therapy nowadays is the treatment of choice, indicating surgical drainage only for extremely aabscesso lesions in which ruptures are believed to be imminent [45,46].

Primary hepatic high-grade non-Hodgkin’s lymphoma and chronic hepatitis C infection. After the old days of splenoportography and less sensitive tests, the non-invasive imaging procedures, including ultrasonography, computerized tomography, magnetic resonance imaging and, principally serology, have dramatically improved the clinician’s ability to promptly diagnosis hepatic amebiasis and quickly start treatment. Hepatogastrenterology ; Num estudo comparativo, realizado por Rajak et al.

There is the risk of sepsis, needing prompt diagnosis and therapy with antibiotics. Surg Clin North Am ; This drug is available in capsules of and mg, and mg for IV infusions.

Non-Hodgkin lymphoma of the gastrointestinal tract. The finding of patients with hepatic amebic lesions who are HIV seropositive, some of them with an infection developed after the onset of amebic liver abscess, seems to be proof of this relationship [57]. Following depression of the protective mucus blanket, trophozoites attach to the cells of interglandular epithelium and, with the aid of proteolytic enzymes that degrade elastin, collagen and fibronectin, especially cysteine proteinase, phospholipase and hemolysin [12], they invade the colonic epithelium by disruption of the extra cellular matrix.

Peptide-mediated lysosome enzymes released by the lysed polymorphonuclear leucocytes and monocytes, contribute to the destruction of host tissue and extend the lesion. Primary lymphoma of the liver: The early diagnosis of hepatic amebiasis by serology and imaging studies, the availability of effective drugs and percutaneous abscewso has made surgical treatment very rare [63].

Rarely, a chronic perforation is described, giving rise to constrictive pericarditis. Surgical considerations in the management of amoebic liver abscess. The trophozoite reaches the liver through the portal system, provoking enzymatic focal necrosis of hepatocytes and multiple micro-abscesses that coalesce to develop a single lesion whose central cavity contains a homogeneous thick liquid, with typically reddish brown and yellow color similar to “anchovy paste”.

Higher rates of mortality are directly linked to serious complications, mainly pericarditis and peritonitis.

It is important to remember that in accordance with the pharmacokinetics of imidazoles, these drugs have a short stay in the bowel lumen, which is not sufficient for an effective action against the amoebas [53].

The extension of the hepatic amebiasis to the pericardium, also through a mechanism of contiguity, is responsible for serious syndromes that range from mild pericarditis to catastrophic purulent pericarditis [38,39,40].
