人巨细胞病毒(HCMV)是一种高度流行的疱疹病毒,它作为潜伏感染持续存在,并已在几种不同的肿瘤类型中检测到。HCMV疾病是罕见的,但可能发生在高风险环境中,通常表现为肺部感染。迄今为止,HCMV尚未在恶性胸膜间皮瘤(MPM)中进行研究。在144名MPM患者的连续病例系列中,我们评估了HCMV的两种生物标志物:IgG血清状态(定义为阳性和阴性)和DNA血症(血清中无细胞HCMV DNA>100拷贝/mL)。大约一半的MPM患者人群是HCMV IgG血清阳性(51%)。HCMV DNA血症在MPM中高度流行(79%),且与IgG血清状态无关。41%的患者存在与高水平当前感染(>1000拷贝/mL血清)一致的DNA血症水平。IgG血清状态和DNA血症均与患者生存率无关。在组织中,我们观察到HCMV DNA存在于48%的肿瘤(n = 40)和只有29%的正常胸膜组织,从个人没有恶性肿瘤(n = 21)。我们的研究结果表明,近一半的MPM患者在治疗时有高水平的当前HCMV感染,胸膜组织可能是潜在HCMV感染的储存库。这些发现值得进一步研究,以确定MPM患者肺部感染的全谱,以及治疗高水平的当前HCMV感染是否可以改善患者的预后。
Human cytomegalovirus (HCMV) is a highly prevalent herpes virus which persists as a latent infection and has been detected in several different tumor types. HCMV disease is rare but may occur in high-risk settings, often manifesting as a pulmonary infection. To date HCMV has not been investigated in malignant pleural mesothelioma (MPM). In a consecutive case series of 144 MPM patients we evaluated two biomarkers of HCMV: IgG serostatus (defined as positive and negative) and DNAemia (>100 copies/mL of cell free HCMV DNA in serum). Approximately half of the MPM patient population was HCMV IgG seropositive (51%). HCMV DNAemia was highly prevalent (79%) in MPM and independent of IgG serostatus. DNAemia levels consistent with high level current infection (>1000 copies/mL serum) were present in 41% of patients. Neither IgG serostatus nor DNAemia were associated with patient survival. In tissues, we observed that HCMV DNA was present in 48% of tumors (n = 40) and only 29% of normal pleural tissue obtained from individuals without malignancy (n = 21). Our results suggest nearly half of MPM patients have a high level current HCMV infection at the time of treatment and that pleural tissue may be a reservoir for latent HCMV infection. These findings warrant further investigation to determine the full spectrum of pulmonary infections in MPM patients, and whether treatment for high level current HCMV infection may improve patient outcomes.
