Background: There are few reports of imported fascioliasis in Spain. This study aimed to describe the characteristics of cases registered in +REDIVI network.
Methods: Observational, retrospective, descriptive study of imported fascioliasis cases registered in the +REDIVI, a multicenter collaborative network collecting information on imported infectious diseases in Spain, from October 2009 to May 2019.
Results: Of 25,203 cases of imported disease registered over the study period, 16 (0.063%) were fascioliasis, acquired mainly in Pakistan, Morocco, Bolivia, and Peru. Clinical, analytical, and therapeutic data were available for 12 cases (6 immigrants, 4 people visiting friends and relatives, 2 travelers). Eleven (91.6%) had eosinophilia. The most frequent symptoms were abdominal pain (n = 5) and cough (n = 5). Two cases (16.66%) were acute and 10 (83.33%) chronic. Two patients presented lung involvement, and four had other parasitic co-infections. Twelve cases (100%) were seropositive for Fasciola hepatica. Ten patients underwent a coproparasitological study, none of which detected Fasciola spp. eggs. The probable food origin (watercress) was confirmed in 3 cases (25%). Nine of the 10 patients treated with triclabendazole (90%) and one patient treated with praziquantel were considered to meet the criteria for cure. One patient was lost to follow-up.
Conclusions: Fascioliasis is a rare imported parasitosis in Spain. Eosinophilia, along with geographical origin, is the main clue for diagnosis.
