[The platelet response as a prognostic factor in invasive amebiasis of the liver].

A group of 96 patients with Invasive Hepatic Amebiasis, was studied in a prospective clinical trial. The platelet count was measured for each patient on admission and on the tenth day of treatment. The patient were classified into two groups: the first one for patients with unfavorable results and the second one for patients with favorable results. The presence of thrombocytosis was significant in the second group, with a sensitivity of 56% and specificity of 70% in the initial determination, and of 82% and 68% at the tenth day respectively. With this finding, it could be considered that thrombocytosis must be a good prognostic indicators in the Amebic Liver Abscess, and it could be possible to include it in a scale to elucidate the prognosis in a quantitative form, of this pathologic entity.
