Human Parvovirus B19 Antibodies Are Less Frequent among Patients Treated with Factor IX Concentrate Inactivated by Ultrafiltration: A Report from a Single Spanish Institution

Prevalence of Human Parvovirus B19 DNA and IgG/IgM Antibodies in Polish Haemophilia Patients

“…The anti–B19 IgG frequency in Polish patients was similar to that found by others [3, 4], but slightly lower than that recently observed among Dutch haemophiliacs [2]. Also the frequency of antibodies in Polish blood donors was lower than in the Dutch study [2], especially if results within similar age groups are compared.…”

“…We have read with interest two papers on the high prevalence of antibodies to human parvovirus B19 in patients with haemophilia or other congenital coagulation disorders, recently published in Vox Sanguinis [2, 3]. We would like to share our experience in this respect.…”
