In a double-blind trial patients with Argentine haemorrhagic fever treated with immune plasma within 8 days of the onset of the disease had a much lower mortality than those given normal plasma. Some patients treated with immune plasma developed late neurological complications.
We have compared the solid-phase radioimmunoassay(SPRIA) with a solid-phase enzyme-immunoassay (EIA) in the detection of hepatitis B surface antigen (HBsAg). 708 sera from blood donors and 500 sera from patients with various diseases (acute and chronic hepatitis, chronic renal failure in hemodialytic treatment) were tested for HBsAg with both methods. 208 sera (17,2%) were found to be positive in SPRIA and 209 sera (17,3%) in EIA. Two HBsAg positive sera were tested in dilution series with both methods, too. The results show that the sensitivity and specificity of the EIA compare very favourably with those of the SPRIA.
