Abstract

Opportunistic infections in the central nervous system (CNS) by JCPyV/BKPyV in HIV/AIDS patients increase morbidity/mortality, especially in low-income countries. In Argentina, data regarding CNS-infection by polyomavirus in HIV/AIDS are scarce. We retrospectively evaluated BKPyV/JCPyV infections in cerebrospinal fluid (CSF) samples of HIV/AIDS patients with meningoencephalitis or Progressive Multifocal Leukoencephalopathy (PML) from Salta, Argentina, a province with high rates of mortality from AIDS.

Cryopreserved CSF samples from all HIV/AIDS patients with BKPyV/JCPyV admitted to a regional referral hospital for one year underwent amplification of 173 pb T-antigen sequence by PCR, searching for polyomavirus DNA. Subsequently, polyomavirus genotyping by direct sequencing was performed.

Six percent (3/50) of the patients with CNS disorders had polyomavirus; one patient with meningoencephalitis had BKPyV, and 2 patients with PML had JCPyV. One genotype 2A was identified.

To our knowledge, this is the first description of BKPyV-associated meningoencephalitis in HIV/AIDS patients in Argentina, together with the first report of JCPyV genotype 2 responsible for neurological disease in a patient with HIV/AIDS in the country. These data support the systematic incorporation of molecular diagnosis for BKPyV /JCPyV into routine screening of CSF in patients with HIV/AIDS and neurological diseases in Argentina. Etiological diagnosis of CNS diseases in these patients is overriding.

BKPyV在阿根廷引起HIV/AIDS患者脑膜脑炎

艾滋病毒/艾滋病患者中枢神经系统（CNS）的JCPyV/BKPyV机会性感染增加了发病率/死亡率，特别是在低收入国家。在阿根廷，关于艾滋病毒/艾滋病中多瘤病毒感染中枢神经系统的数据很少。我们回顾性评估了阿根廷萨尔塔省艾滋病死亡率高的艾滋病毒/艾滋病脑膜脑炎或进行性多灶性脑白质病（PML）患者脑脊液（CSF）样本中的BKPyV/JCPyV感染情况。对所有在某地区转诊医院住院一年的BKPyV/JCPyV HIV/AIDS患者冷冻保存的脑脊液样本，采用PCR扩增173 pb t抗原序列，寻找多瘤病毒DNA。随后，通过直接测序进行多瘤病毒基因分型。6%（3/50）的中枢神经系统疾病患者携带多瘤病毒；脑膜脑炎1例合并BKPyV， PML 2例合并JCPyV。鉴定出1个基因型为2A。据我们所知，这是阿根廷首次描述艾滋病毒/艾滋病患者中bkpyv相关的脑膜脑炎，以及该国首次报告导致艾滋病毒/艾滋病患者神经系统疾病的JCPyV基因2型。这些数据支持将BKPyV /JCPyV分子诊断系统地纳入阿根廷艾滋病毒/艾滋病和神经系统疾病患者脑脊液常规筛查。在这些患者中，中枢神经系统疾病的病因学诊断是最重要的。
