Indirect immunofluorescence is also very helpful, giving values higher than 1: Nowadays, the prognosis of hepatic amebiasis, diagnosed early and properly treated, is quite favorable and mortality should be approximately zero. Differential Diagnosis Despite a similarity with several diseases such as hepatoma, acute cholecystitis, parasitic cysts, subphrenic and pulmonary abscesses provoked by bacteria, the differential diagnosis of hepatic amebiasis must be established principally against pyogenic abscess [30,31].

In addition to its low cost and accessibility, it has the ability to rapidly detect hepatic lesions at the different stages of the disease, determining their number, size and exact position Figure 6. Tumor calcification following therapy.

J Comput Assist Tomogr ;7: During the last few years two imidazole derivates have been introduced in Brazil, both with high amebicide action and an extended half-life, especially secnidazole [49].

In this situation there is a decrease in the ability abscesso breathe, and the patient complains of dyspnea. 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 amwbiano to eradicate cysts and trophozoites from the intestine.

The recovering of trophozoites and cysts of Entamoeba histolytica in feces of patients with hepatic amebiasis strengthens the hypothesis of amebic etiology. Enviado por Lais flag Denunciar.

In chronic forms the fever is low and develops more gradually, without chills or sweating. Digital morphometrics was used to quantify all immune positive staining and to calculate necrotic areas. The abdominal CT scan is another valuable imaging procedure, with greater resolution and sensitivity in detecting hepatic lesions, especially the smaller ones, which is useful for early diagnosis [27].

Hepatic amebiasis

Computed tomography of hepatocellular carcinoma. 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]. Diagnosis 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.

Nitazoxanide, a abscrsso, recently introduced, drug, with efficacy against cysts and trophozoites of Entamoeba histolytica has shown good results in the treatment of intestinal amebiasis [52].

In spite of the important support provided by imaging studies, the definitive confirmation of hepatic amebiasis is based on a demonstration of Entamoeba histolytica trophozoites in the aspirated pus, or more frequently from the necrotic material obtained by needle biopsy of the edge or the bottom of the lesion.

Bombay H J ; Imaging of fibrolamellar hepatocellular carcinoma. Bombay Hosp H ; J Comput Assist Tomogr ;6: Positive correlation was found between the number of trophozoites and inflammatory cells.

In Brazil, though there is lack of national reports, the incidence of hepatic amebiasis differs from one region to another, being uncommon in the south and prevalent in the north [3,4]. Calcifying liver metastases in a case of primary lung cancer. Indications for aspiration of amebic liver abscess. Surgery ; Clinical profile of multiple amoebic abscesses, J Assoc Physicians India ; Since most of the blood supply from the large gut drains into the right lobe of the liver through the portal system, translocated organisms, such aerobic and anaerobic Enterobacteriaceae, may reach the hepatic sinusoids, being phagocytized most of the time.

Pathology of human amebiasis. The scarcity or absence of trophozoites in the groups treated with dexamethasone suggests the importance of the inflammatory response in the production of amebic liver abscess, despite the inherent parasite virulence to be determinant in establishing the injury. Under these circumstances Staphylococcus aureus is the principal invader [20].
