Fascioliasis is a trematode flatworm infection caused by Fasciola hepatica and F. gigantica. Fasciola hepatica is mesoendemic in Turkey. Sixcases of pediatric fascioliasis are presented here. All patients had histories of consumption of various raw vegetables. Four of our patients wereat the hepatic phase, and two were at the biliary phase. Except for onepatient, all patients had eosinophilia. In three patients, total IgE levelswere markedly increased. In these patients, there was an eosinophilicleukomoid reaction accompanied by a high total IgE level. Except forone of our patients, all patients had positive indirect hemagglutinationtests. This patient was diagnosed as having fascioliasis with a compatible clinical picture. Except one, all of our patients were completelytreated with a single-treatment regimen of triclabendazole; one patientneeded re-administration. Only in patient 1, liver enzymes increased after triclabendazole administration because he had taken the medicationfor longer than prescribed by mistake. The elevation of liver enzymeswas not observed in the other patients who received the correct dose.All patients recovered completely with triclabendazole treatment. Thepatients’ dietary habits, eosinophilia, and markedly elevated IgE levelsmay be significant predictors for physicians to suspect fascioliasis.
