OBJECTIVE Different intravenous immunoglobulins (IVIGs) were found to be GB virus C/hepatitis G virus polymerase chain reaction (GBV-C/HGV-PCR)-positive. The potential transmission of this virus to recipients by a PCR-positive IVIG batch was investigated. METHODS Polyclonal IVIGs of different manufacturers and with different virus inactivation procedures were analyzed by GBV-C/HGV-PCR and anti-E2-ELISA. Follow-up sera of 13 participants of a clinical trial performed with a GBV-C/HGV-PCR-positive batch were retrospectively investigated for GBV-C/HGV seroconversion (specific antibodies, viral RNA). RESULTS Four out of ten IVIGs analysed by GBV-C/HGV-PCR were - at least for some batches - virus genome-positive. Virus inactivation by solvent/detergent treatment resulted in GBV-C/HGV-PCR-negative products. GBV-C/HGV-specific antibodies were detectable in all IVIGs analyzed. There was no transmission of GBV-C/HGV observed when recipients of a large amount of a GBV-C/HGV-PCR-positive batch were analyzed by an antibody test and specific PCR. CONCLUSIONS Despite PCR positivity of an IVIG preparation no transmission of GBV-C/HGV to recipients was observed. Possible explanations are a sufficient virus inactivation procedure and/or presence of specific antibodies in the final products.

D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D006525	Hepatitis, Viral, Human	INFLAMMATION of the LIVER in humans due to infection by VIRUSES. There are several significant types of human viral hepatitis with infection caused by enteric-transmission (HEPATITIS A; HEPATITIS E) or blood transfusion (HEPATITIS B; HEPATITIS C; and HEPATITIS D).

D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
