Indirect fluorescent antibody test in diagnosis of acute fasciolitic syndrome.
250 patients with fever, hepatomegaly and eosinophilia were investigated for parasitic infection by stool, urine, thick blood smear examination and sero-diagnosis (ELISA for anti-Toxocara and IFA for anti-Fasciola). Those with patent parasitic infections (41) and anti-Toxocara seropositivity (10) were excluded from follow up. The other were 3 months followed up. The detected infections were 10 Ascaris, 15 Strongyloides, 20 Toxocara, and 25 Schistosoma mansoni. Other 30 were positive for Fasciola eggs. No other infections were found in the remained 109 patients. IFA anti-Fasciola antibody titres were significantly higher among Fasciola group than any other groups. It is concluded that IFA anti-Fasciola antibody titre greater than or equal to 1/256 with ethanol fixed antigen sections is of value in diagnosis of acute fasciolitic hepatic syndrome.
