Parvovirus B19 infection is often associated with acute and chronic joint diseases thus suggesting an etiologic role for the virus in these pathologies. In this work, we looked for a possible correlation between Parvovirus B19 infection and certain types of chronic inflammatory rheumatisms. We therefore, screened a population of 100 patients with different chronic inflammatory rheumatismal affections for serological markers of Parvovirus B19 infection. All patients were Tunisians of both sexes, who presented at the service of Rheumatology of the Charles Nicolle Hospital, Tunis. One hundred blood donors were taken as controls. Specific Immunoenzyme Assays of the ELISA type (Biotrin International, France) were used to detect anti-Parvovirus IgG and IgM. On the other hand, viral DNA was sought by nested PCR in synovial fluid from 14 patients. The data obtained indicate that specific anti-Parvovirus B19 IgG was detectable in the sera of 80.7% of patients and 43% of controls. In contrast, none of the sera was found positive for specific IgM antibodies. Synovial fluid samples could be collected from 14 anti-Parvovirus B19 seropositive patients and were tested for the presence of viral DNA. None of the samples was found positive. The results of our serological study reinforce the hypothesis that Parvovirus B19 infection is associated with rheumatismal joint affections. However, the lack of detectable viral DNA in synovial fluid of the tested seropositive patients points to an indirect role of the virus in these joint disorders.
细小病毒B19感染常与急慢性关节疾病相关,因此提示该病毒在这些病症中具有病因学作用。在本研究中,我们探寻了细小病毒B19感染与某些类型的慢性炎症性风湿病之间可能存在的关联。为此,我们筛查了100例患有不同慢性炎症性风湿性疾病的患者,以检测其细小病毒B19感染的血清学标志物。所有患者均为突尼斯男女患者,他们在突尼斯市查尔斯·尼科勒医院的风湿病科就诊。选取100名献血者作为对照。采用ELISA类型的特异性免疫酶测定法(法国Biotrin国际公司)检测抗细小病毒IgG和IgM。另一方面,通过巢式PCR在14例患者的滑液中寻找病毒DNA。所获数据表明,80.7%的患者血清和43%的对照血清中可检测到特异性抗细小病毒B19 IgG。相比之下,未发现任何血清中特异性IgM抗体呈阳性。可从14例抗细小病毒B19血清阳性患者中采集滑液样本,并检测其中是否存在病毒DNA。未发现任何样本呈阳性。我们的血清学研究结果强化了细小病毒B19感染与风湿性关节疾病相关的假说。然而,在检测的血清阳性患者的滑液中未检测到可检测到的病毒DNA,这表明该病毒在这些关节疾病中起间接作用。
