Two cases of amebic abscess of the liver are described. On the other hand, subjects with ALA had an epidemiological history of travel or immigration. J Hepatol ; Medicine Baltimore ; A diagnosis of pyogenic abscess was initially entertained, due to the absence of epidemiologic risk factors and the negative serology for Entamoeba histolytica. Amebic liver abscess with bacterial superinfection in a patient with no epidemiologic risk factors.
The radiological findings are those of a liver abscess and consist of a low density collection on CT or a hypoechogenic lesion on ultrasonography, with posterior acustic shadowing and inner echos that mobilize with postural changes.
There are small series of cases and isolated cases described in the literature Blood tests for both types of abscesses are similar: In developed countries such as the United States, it is unusual and is most commonly nepatico in immigrants from and travelers to developing countries 2. The increase of the number of cases in the absence of epidemiologic risk factors in our country, as derived from the increasing number of cases lately reported, and the yepatico case, lead to consider the existence of autochthonous cases.
This procedure was successful in 18 full recovery Print Send to a friend Export reference Mendeley Statistics.
The treatment for ALA consists of the intraluminal and systemic administration of amoebacides as soon as possible. Med Clin Barc ; How to cite this article. Study of 20 cases with literature review. The following variables were taken into account: There is no current evidence whether guided percutaneous drainage provides extra benefits amebian to treatment with metronidazole alone in uncomplicated ALA cases A percutaneous drainage was performed on 22 patients.
Of the 13 cases of ALA 7 men and 6 women, with mean age of 42,9 years2 were locally acquired. Departments of 2 Internal Medicine, 3 Radiology, and 4 Microbiology.
Absceso hepático piógeno versus amebiano: Estudio clínico comparativo de una serie de 58 casos
However, both CT scans and echography may lead to false negatives in abscesses smaller than 1 cm in amebuano, in those located near the diaphragmatic dome, and in those in early stages of development. In addition, predisposing diseases and the origin of abscesses for pyogenic abscesses 45 casesand associated diseases, epidemiological history of travelling to areas with a high prevalence of amoebiasis, the origin of patients, and the time between having been to endemic areas and the occurrence of symptoms in amoebic cases 13 cases were analysed.
Icterus absesso often associated with biliary pathology. Currently, a very specific technique which can be used for the diagnosis of ALA as long as the subject has not been treated with amoebacides is the presence of adhesin Gal-GalNac in the serum However, it represents one of the few series in our country 12 in which the clinical pictures of these two types of liver abscesses are compared.
Piperaciline-tazobactam was added, with resolution of fever and marked improvement in the patientacute;s condition. Little, Brown and Company,pp.
Pyogenic liver abscess was defined as the observation of one or more ultrasound and CT images with positive cultures, or by positivity in two or more blood cultures of germs consistent with heppatico diagnosis. A clinical comparison of amebic and pyogenic abscess of the liver in sixty-six patients.

Abscess and blood cultures were positive in SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. The possibility of ALA should be entertained even in the absence of history of exposure, and serology should be repeated in suspected cases with an initially negative result. The microbiologic diagnosis is based on the detection of the parasite in the abscess aspirate, although this is an uncommon finding due to the necrotic nature of the abscess Si continua navegando, consideramos que acepta su uso.
This is probably what happened in our case, when the negative serology associated to the absence of epidemiologic risk factors misled to the diagnosis of pyogenic abscess, and subsequently, an early percutaneous drainage was performed.
There was no need for a second percutaneous drainage. Infect Med ; Ojeda 2I. The sensitivity increases in the second to third week of the infection.
Translators working for the Journal are in charge of the corresponding translations. A total of It has also been reported in imunosuppressed patients, HIV patients, patients on corticosteroids or amdbiano from chronic infections like tuberculosis or syphilis and patients who have undergone post-traumatic splenectomy. Molecular genetic techniques and new experimental models have increased the knowledge on the pathogenesis of amebiasis.
Serum tests are usually very helpful in the diagnosis of the disease. PHA has a variable occurrence in the population according to concomitant diseases. The clinical history of patients with amoebic abscesses included: In amoebic abscesses amebjano methods were used:
