Certain clinical manifestations of coronavirus disease (COVID-19) mimic those associated with human herpesvirus (HHV) infection. In this study, we estimated the prevalence of herpesvirus in patients with COVID-19 and determined if coinfection is associated with poorer outcomes and neurological symptoms.
We analyzed samples of 53 patients diagnosed with COVID-19. The samples were evaluated for the presence of alphaherpesviruses, betaherpesviruses, and gammaherpesviruses, and the viral loads were quantified using quantitative polymerase chain reaction (qPCR) method.
Among the patients, in 79.2% had detection at least one type of herpesvirus. HHV-6 (47.2%), cytomegalovirus (43.3%), and HHV-7 (39.6%) showed the highest detection rates. Patients with a high severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) load were more likely to show herpes simplex virus 1 detection (p = 0.037). Among patients coinfected with SARS-CoV-2 and HHVs, 26.4% showed central nervous system-associated neurological symptoms and herpetic manifestations. A statistically significant association was observed between neurological changes and HHV-6 detection (p = 0.034).
The findings showed a high prevalence of herpesvirus in patients with COVID-19. Furthermore, even though SARS-CoV-2 and HHV coinfection was not associated with poorer outcomes, the findings demonstrated the association between neurological symptoms and HHV-6 detection.
冠状病毒病(COVID-19)的某些临床表现与人类疱疹病毒(HHV)感染有关。在这项研究中,我们估计了 COVID-19 患者中疱疹病毒的流行情况,并确定了合并感染是否与较差的结局和神经症状有关。
我们分析了 53 名确诊 COVID-19 患者的样本。使用定量聚合酶链反应(qPCR)方法评估样本中是否存在α疱疹病毒、β疱疹病毒和γ疱疹病毒,并定量检测病毒载量。
在患者中,79.2%的患者至少检测到一种类型的疱疹病毒。HHV-6(47.2%)、巨细胞病毒(43.3%)和 HHV-7(39.6%)的检出率最高。高载量严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)的患者更有可能检测到单纯疱疹病毒 1(p=0.037)。在 SARS-CoV-2 和 HHVs 合并感染的患者中,26.4%出现与中枢神经系统相关的神经症状和疱疹表现。在神经变化和 HHV-6 检测之间观察到统计学显著关联(p=0.034)。
研究结果表明 COVID-19 患者中疱疹病毒的流行率很高。此外,尽管 SARS-CoV-2 和 HHV 合并感染与较差的结局无关,但研究结果表明神经症状与 HHV-6 检测之间存在关联。
