为了确定慢性B19关节病患者的B19感染是否持续存在,通过IgM血清学记录成人的急性B19感染。在4例出现慢性关节症状的患者中,在急性感染后24-42个月获得骨髓穿刺液。通过聚合酶链反应,使用病毒衣壳基因中的B19特异性DNA序列,并使用B19特异性DNA结合蛋白Southern分析进行探测,扩增骨髓穿刺液中的DNA。在所有4名慢性关节病患者中检测到B19特异性DNA序列,而7名抗B19 IgM−、IgG−和6名抗B19 IgM−、IgG+正常骨髓供体中分别为0和0。3例经血清学证实的急性B19感染和急性但非慢性关节症状的患者在感染后2-18个月的骨髓穿刺液中检测到B19 DNA。这些发现表明B19关节病与B19病毒或选择的B19 DNA序列的持续存在有关。
To determine if B19 infection persists in patients with chronic B19 arthropathy, acute B19 infection in adults was documented by IgM serology. Bone marrow aspirates were obtained 24-42 months after acute infection in 4 patients who developed chronic joint symptoms. DNA from bone marrow aspirates was amplified by polymerase chain reaction by using B19-specific DNA sequences in the viral capsid gene and probing with B19-specific oligonucleotidesin Southern analysis. B19-specific DNA sequences were detected in all 4 chronic arthropathy patients compared with 0 of 7 anti-B19 IgM−, IgG−and 0 of 6 anti-B19 IgM−, IgG+normal bone marrow donors. Three patients with serologically proven acute B19 infection and acute but nonchronic joint symptoms had B19 DNA detected in bone marrow aspirates 2-18 months after infection. These findings suggest that B19 arthropathy is associated with persistence of either B19 virus or select B19 DNA sequences.
