Human Fascioliasis: Comparison of a Fasciolicidal Effect of Bithionol and Praziquantel

There is no consensus about the optimal treatment for fascioliasis. Here we report 5 cases of fascioliasis and 12 cases of fascioliasis reviewed from the literature, and discuss the clinical characteristics and treatment of this parasitic disease. The diagnosis was made in 88% of all patients by the serological test and eggs in the feces were negative in all patients. The characteristic CT findings of all patients in our series were cluster of multiple abscess-like lesions in the liver. Eosinophilia was present in all patients. Bithionol was effective in all of the 13 patients and praziquantel was effective in 4 of 8 patients. Three of 4 patients, in whom praziquantel was not effective, were treated with bithionol successfully. No severe side effects were noticed in all patients. Bithionol seems to be more effective against fasciola sp. than praziquantel. Bithionol is proposed as the drug of choice for the treatment of human fascioliasis.
