The human cytomegalovirus (HCMV) is a common pathogen which usually remains asymptomatic in the healthy adults; however, it can cause a symptomatic disease in the immunocompromised patients. The risk of infection with HCMV increases in ulcerative colitis (UC) patients as a result of receiving immunosuppressive agents.
This study aimed to determine the prevalence and the glycoprotein B genotypes of HCMV among the patients with HCMV disease superimposed on an UC flare that required hospitalization in Imam Khomeini Hospital in Ahvaz, Iran, during 2010- 2012.
In this case-control study, formalin-fixed paraffin-embedded intestinal tissue samples were taken from 98 patients with UC disease including 53 males and 45 females (mean age ± standard deviation, 38.95 ± 17.93) and 67 control patients with noninflammatory disease who were referred to Imam Khomeini Hospital during 2010-2012. Detection of HCMV genome in intestinal samples was carried out by seminested polymerase chain reaction. Glycoprotein B genotypes were determined by sequencing.
Among 98 patients with UC, only 12 (12.2%) patients were positive for HCMV genome, while the HCMV genome was not detected in any of the controls. (P = 0.002). The distribution of HCMV gB genotypes in 12 CMV-positive UC patients was as follow: gB1, 11 (91.7%) and gB3, 1 (8.3%). The most prevalent genotype in CMV-positive UC patients was gB1.
In this study, high prevalence of 91.7% HCMV gB1 genotype was predominant among HCMV-positive UC patients, which suggests that there might be an association between HCMV gB genotype 1 and UC disease.
人巨细胞病毒（HCMV）是一种常见病原体，在健康成年人中通常无症状；然而，它可在免疫功能低下的患者中引起有症状的疾病。由于接受免疫抑制剂治疗，溃疡性结肠炎（UC）患者感染HCMV的风险增加。
本研究旨在确定2010年至2012年期间在伊朗阿瓦士伊玛目霍梅尼医院因UC病情发作需要住院治疗且合并HCMV疾病的患者中HCMV的流行率和糖蛋白B基因型。
在这项病例对照研究中，从98例UC疾病患者中获取福尔马林固定石蜡包埋的肠道组织样本，其中包括53例男性和45例女性（平均年龄±标准差，38.95±17.93），以及2010年至2012年期间转诊至伊玛目霍梅尼医院的67例非炎性疾病对照患者。通过半巢式聚合酶链反应检测肠道样本中的HCMV基因组。通过测序确定糖蛋白B基因型。
在98例UC患者中，只有12例（12.2%）患者的HCMV基因组呈阳性，而在任何对照患者中均未检测到HCMV基因组。（P = 0.002）。12例CMV阳性UC患者中HCMV gB基因型的分布如下：gB1，11例（91.7%）和gB3，1例（8.3%）。CMV阳性UC患者中最常见的基因型是gB1。
在本研究中，HCMV阳性UC患者中HCMV gB1基因型的高流行率占主导地位，这表明HCMV gB1基因型与UC疾病之间可能存在关联。
