A very useful update considering casuistics is defined by
Meltzer E. 'Eosinophilia among returning travellers: a practical
approach'. Am J Trop Med Hyg. 2008 ; 78: 702-9 or the update of Jeng MR (Hematologic
problems in immigrants from Southeast Asia. Hematol Oncol Clin North Am 2004; 18 : 1405-22).
The differental diagnosis between absolute and relative eosinophilia
( > < 450 / microl ), and the importance of parasitic co-infection
in up to one fourth of travellers with eosinophilia would be the main hallmarks
in these guidelines, added to coprologic studies in south hemisphere areas
(Strongyloides spp, Schistosoma spp, Knott test , urine parasites ) and
antigenic/molecular diagnostic (Trichinella spp, fasciola, Wuchereria
brancofti) studies.
