Lipid-enveloped viruses such as HIV, HBV, and HCV can be inactivated by treatment with solvents and detergents. HAV and human parvovirus B19 lack lipid envelopes and are not inactivated. Solvent/detergent-treated pooled plasma (S/D plasma) contains neutralizing antibodies, but it is not known whether the parvovirus B19 antibody content is sufficient to prevent transmission of the disease. A patient is described who developed a clinical illness due to parvovirus B19 infection after the infusion of S/D plasma.
A 36-year-old woman with myasthenia gravis underwent five plasma exchange procedures from January 15 to January 25, 1999, using albumin, except for 5 units of SD plasma given because of a low fibrinogen level. Four of the 5 units were implicated in a recall after high levels of parvovirus B19 DNA were found in several lots. Two weeks after the infusion, the patient developed fatigue, a rash, and severe polyarthralgias. Parvovirus B19 IgG and IgM antibody titers were consistent with an acute infection.
Clinically apparent parvovirus B19 infection can follow the use of S/D plasma that contains high levels of parvovirus B19 DNA.
诸如HIV、HBV和HCV等有脂质包膜的病毒可用溶剂和去污剂处理使其失活。甲型肝炎病毒(HAV)和人细小病毒B19没有脂质包膜,不会被灭活。经溶剂/去污剂处理的混合血浆(S/D血浆)含有中和抗体,但尚不清楚细小病毒B19抗体含量是否足以预防疾病传播。本文描述了一名患者,其在输注S/D血浆后因感染细小病毒B19而出现临床疾病。
一名36岁重症肌无力女性患者于1999年1月15日至1月25日接受了5次血浆置换,除因纤维蛋白原水平低而输注了5单位S/D血浆外,其余均使用白蛋白。在数批血浆中发现高水平的细小病毒B19 DNA后,对这5单位中的4单位进行了召回。输注两周后,患者出现疲劳、皮疹和严重的多关节痛。细小病毒B19 IgG和IgM抗体滴度与急性感染相符。
使用含有高水平细小病毒B19 DNA的S/D血浆后,可能会发生临床上明显的细小病毒B19感染。
