Parvovirus B19 (B19), which may contaminate red cell components for blood transfusion, is known to be resistant to several viral inactivation methods. To increase the safety of hemoglobin solutions as a source of red cell substitutes, we investigated the removal of parvovirus B19 from hemoglobin solution using nanofiltration. The hemoglobin solution spiked with parvovirus B19 was tangentially filtered using the BMM-35 filter (mean pore size of 35 nm) followed by BMM-15. The parvovirus B19 of 10(8.5) PT50 (median PCR titer)/10 microL was not changed after the BMM-35 filtration. However, the BMM-15 filtration decreased the parvovirus B19 from 10(8.3-8.7) PT50 to 10(1.3-2.2) PT50, indicating more than 6 log10 reduction. When the initial parvovirus B19 of 10(6.0) PT50 was subjected to the BMM-15 filtration, the residual virus was 10(-0.3-0.5) PT50 orundetected in some fraction of the filtrate. Hemoglobin recovery was 70.4 +/- 3.4%. The ratio of methemoglobin was not changed during the filtration. These findings indicate that the BMM-15 filtration is a promising approach to prepare a safer hemoglobin solution for red cell substitutes.
