Population-based study of the epidemiology of and the risk factors for pyogenic liver abscess.

In our series, the clinical parameters suggesting pyogenic origin were: Both systems act together, first to activate and amplify local inflammatory response for contention and elimination amebianoo the pathogen, and lately regulation of immune response and tissue repair Bellinger et al.

In 10 patients, diabetes was considered to be a predisposing condition. Hepatic lesions diagnosed by imaging techniques, but without positive cultures of the pus, were included after ruling out other diseases according to the clinical history.

West J Med ; We reported the mean of cells per hepatici unit in square millimetres. B Significantly increased density of neutrophils was observed when rats were chemically sympathectomized in comparison with control and vehicle. World J Surg ; We found that immune cells showed different quantities and patterns of distribution. As known, all organs of the immune response are innervated by the sympathetic and parasympathetic systems, and almost all immune cells have receptors to neurotransmitters, neuropeptides and hormones Blalock, You can change the settings or obtain more information by clicking here.

Control, vehicle and sympathectomized groups were induction of amebic liver abscess E. C Significantly decreased secretion of the proinflammatory TNF-a was achieved in chemical sympathectomy and inoculated rats. Neuroregulation of the neuroendocrine compartment of the liver.


Diet consisted of Purina Chow and water ad libitum throughout the entire experiment. This therapeutic regimen should heppatico followed by a luminar agent like paramomycin for a period of seven days 2.

No significant differences were observed on NK cells in analysed groups. The percutaneous aspiration can cause the superinfection of the ALA, so it should be avoided in those cases with no indication.

Absceso hepático piógeno versus amebiano: Estudio clínico comparativo de una serie de 58 casos

Chemically sympathectomized and inoculated rats had significant decrease of IFN-g Histological sections of 5 mm were obtained with the microtome Leica RM RT for histochemistry, immunohistochemistry and immunofluorescence studies. Nevertheless, this technique lacks the specificity that was initially believed Diagnosis of amebic liver abscess and intestinal infection with the TechLab Entamoeba histolytica II antigen detection and antibody tests.

However, both CT scans and echography may lead to false negatives in abscesses smaller than 1 cm in diameter, in those located near the diaphragmatic dome, and in those in early stages of development. Sometimes, the abscess only causes fever.

nepatico Clinical characteristics depend on the pathogenic mechanism involved. Taken together, these results suggest that chemical sympathectomy induced trophozoites to reduce significantly their invasive capacity with evident decrease of fibrosis and granuloma formation.

Hospital de la S. The patient remained afebrile for 48 hours with subsequent recurrence of the high temperature.


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. The abdominal pain improved, but the patient remained with high temperature.


Servicio de Aparato Digestivo. The mechanism of natural resistance in the rat to Entamoeba histolytica. A Macroscopic and microscopic analyses of ALA in rats.

Gastroenterol Clin North Am ; There is no current evidence whether guided percutaneous drainage provides extra benefits compared to treatment with metronidazole alone in uncomplicated ALA cases Trop Med Int Health ; 8: Neuroendocrine regulation of immunity. Tratado de Medicina Interna de Cecil-Loeb, 9. Changes in etiology, management and outcome. An early and accurate diagnosis avoids a higher morbi-mortality, as the treatment for ALA differs from that of the pyogenic abscess. The amebic liver abscess ALA has a worldwide incidence of 50 cases per year 1.

The treatment of patients with PHA consisted of antibiotherapy, drainage and surgery. In control and vehicle groups, neutrophils were located mainly in fibrotic area; meanwhile, in chemical sympathectomized and inoculated rats we observed undifferentially distributed neutrophils inside and outside the damaged area Fig.

En esto, nuestra serie coincide con lo publicado por diferentes autores 1,2. Innate immunity to amebic liver abscess is dependent on gamma interferon and nitric oxide in a murine model of disease. The three-directional communication among the immune, nervous and endocrine systems occur in three ways:
