АCUTE INFECTION OF OPISTHORCHIS FELINEUS IN MOSCOW: CASES FROM DELIVERED FISH AND CASES IN TOURISTS TRAVELLED TO ENDEMIC REGIONS IN RUSSIA

Abstract

We describe the human acute opisthorchiasis outbreaks in Moscow region acquired from eating raw Leuciscus idus, Abramis brama and Aspius aspius in 10 patiens: 5 delivered fish from Tyumen and Sverdlovsk regions and 5 – from fish during their travelling to Tomsk and Astrakhan regions. Although, 18 people had identical history of consumption raw fish 10 had clinical symptoms of which the most frequent one was febrile eosinophilic syndrome. Other 8 people had no clinical symptoms. Eggs of O.felineus were found in 10 patients. Due to risk of cholangiocarcinoma in patients infected with O.felineus we recommend one day of praziquantel 25 mg/kg TID. Although opisthorchiasis is not frequently reported in Moscow region, it should be considered in cases of unexplained acute febrile eosinophilic syndrome with cholestasis, especially when patients confirm the ingestion of raw fish.
