Cytomegalovirus (CMV) infection is currently prevalent in populations throughout the world, and 56%‍-94% of the global population is seropositive for CMV. CMV infection mainly affects immunocompromised hosts. In these cases, it can cause significant symptoms, tissue-invasive disease, and many sequelae including death (Dioverti and Razonable, 2016). The vast majority of healthy adults with CMV infection experience an asymptomatic course; when symptomatic, it manifests as a mononucleosis-like syndrome in approximately 10% of patients (Sridhar et al., 2018). The gastrointestinal tract and central nervous system appear to be the most frequent sites of severe CMV infection in immunocompetent individuals (Rafailidis et al., 2008). However, CMV infection is relatively rarely recorded in immunocompetent hosts.

Cytomegalovirus (CMV) is an important cause of opportunistic infection in immunocompromised patients. CMV infection occurs as a result of the cell-mediated immunity change in lymphoma patients. Although CMV can cause ulceration anywhere in the gastrointestinal (GI) tract in immunocompromised patients, only a few case reports about CMV GI infection in malignant lymphoma have been documented in literature. Furthermore, it was rare that CMV gastric ulcer with massive bleeding presented as an initial manifestation in a patient who has been not diagnosed lymphoma. We report a case of CMV induced gastric ulcer as an initial manifestation in patient with Hodgkin's disease.

Cytomegalovirus (CMV) infection is usually subclinical in immunocompetent individuals, however it can be life threatening in an elderly immunocompetent individual. We report a case of CMV enteritis causing ileal perforation in a physically active elderly man. An 88-year-old healthy man presented with abdominal pain and diarrhea. After initial conservative treatment, emergency laparotomy was performed for ileal perforation. The diagnosis of CMV enteritis was based on histological findings revealing many large cells with CMV inclusion bodies in the surgical specimen. In elderly individuals, even though they are immunocompetent, CMV enteritis may result in major complications such as bowel perforation, and it should be included in the differential diagnosis of diarrhea if it is resistant to conventional treatment.

Cytomegalovirus retinitis (CMVR) is the commonest opportunistic ocular infection in patients with human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS), typically occurs when CD4+ T cell counts fall below 50/mm3. CMVR accounts for the majority of the vision loss associated with HIV-related eye diseases. However progress in the studies on CMVR, including the prevalence, clinical features, differential diagnosis and recent advances in the management of CMVR is reviewed.

To investigate the correlation between serum cytomegalovirus (CMV) IgM antibody/viral load and infection-related clinical symptoms in neonates infected with CMV, and provide basis for clinical assessment and monitoring of neonatal CMV infection. A total of 70 neonates with CMV infection admitted to neonatology in Women's Hospital, School of Medicine Zhejiang University, from January 2014 to December 2020 were included in this study. Using real-time quantitative PCR as the diagnostic criteria, congenital cytomegalovirus-infected neonates (n=29) was diagnosed within the first 3 weeks of life, otherwise, it was postnatally acquired cytomegalovirus infection (n=41). The differences in general information and clinical indicators between IgM antibody positive and negative patients were analyzed, combined with the PCR result, the correlation between the IgM/viral load and the occurrence of symptoms were analyzed. T-test and non-parametric test were used to compare the differences of indicators between groups, logistic regression was used for multivariate analysis, and ROC curve was used to evaluate the auxiliary diagnostic value of relevant indicators. In the congenital CMV infection group and the postnatally acquired CMV infection group, viral load and the proportion of symptomatic patients in IgM positive group were significantly higher than IgM negative group (Z=-2.616, P=0.008; 80% vs. 21%, P=0.005) (Z=-2.405, P=0.016; 56% vs. 19%, P=0.025). Logistic regression analysis of the included population showed the risk factors of CMV infection-related symptoms were IgM positive (OR 4.562, 95%CI:1.461-14.246,P=0.009) and viral load (OR 1.728, 95%CI:1.068-2.798,P=0.026). Regressive analysis for single symptom with correction showed IgM antibody positive was associated with hearing dysfunction(OR 3.954, 95%CI:1.066-14.677,P=0.040),the CMV viral load was associated with thrombocytopenia (OR 2.228, 95%CI:1.124-4.413,P=0.022), and brain imaging abnormalities (OR 3.956, 95%CI:1.421-11.011, P=0.008). Receiver operating characteristic (ROC) analysis showed the area under ROC curve of CMV viral load for brain imaging abnormalities was 0.883 (P<0.001), with a sensitivity of 75.0% and specificity of 90.3%. For neonates infected with CMV, the risk of infection-related clinical symptoms and hearing dysfunction may be increased when IgM antibody was positive. Meanwhile, the higher the CMV viral load at diagnosis, the higher the risk of thrombocytopenia and abnormal brain imaging.

CMV infection may occur anywhere in the gastrointestinal tract. Among the small intestine, ileum is the most common site of CMV disease and infection of jejunum is a rare one in patients with CMV gastroenteritis. Although rare, the reason why the recognition of this diagnosis is important is that it cause the lethal hemorrhage and perforation of gastrointestinal tract when its diagnosis and treatment was delayed. Rapid diagnosis are able to using the immunohistochemical stain in shell vial culture of infected specimen or peripheral neutrophils preparation in viremic patients within 8 to 36 hours. The treatment of choice is antiviral agent or surgical resection. We experienced a case of CMV disease of jejunum in patient with non-Hodgkin's lymphoma who showed severe ulceration in jejunum and massive intestinal hemorrhage, and he survived after successful treatment with segmental resection of jejunum and intravenous ganciclovir.

A 32-year-old man, who had no previous medical history, was hospitalized with 3-week duration of abdominal pain, fever, and watery diarrhea. Initial colonoscopy showed subepithelial hemorrhagic spots throughout the entire colon together with well-circumscribed ulcer around the ileocecal valve. Serologic test disclosed HIV-positive and repeated biopsies at ulcer base finally revealed that the patient had cytomegalovirus ulcer in ileocecal area.

OBJECTIVETo investigate the role of real time quantitative polymerase chain reaction (RQ-PCR) in the diagnosis and treatment of recipients cytomegalovirus (CMV) infection after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODS318 patients received allo-HSCT were studied. 160 patients received transplants from HLA matched sibling donors; 127 from HLA mismatched related donors; 31 from unrelated donors. Before transplant recipients and donors received CMV serological test by ELISA. After transplant RQ-PCR was used to test and monitor CMV-DNA in plasma of patients. A positive CMV-PCR was defined as > 6 x 10(2) copies/ml. Ganciclovir was used for CMV prophylaxis in all patients at -9 d to -2 d of conditioning regimen period. Ganciclovir, foscarnet, or combination of the two drugs were used as the preemptive therapy.

RESULTSThe total 100-day cumulative incidence of CMV infection was 40.6%. The incidence was 17.5%, 66.1% and 45.2% for the HLA matched sibling, HLA mismatched related (MMR) and unrelated donor (MUR) HSCT respectively. Multivariate analysis showed MMR HSCT, MUR HSCT, ATG containing preparative regimen and moderate to severe aGVHD were the risk factors for CMV infection after HSCT. The 100 day cumulative incidence of CMV disease was 8.8% and 5.6%, 9.4%, 22.6% respectively for total and three kinds of HSCT after early preemptive therapy. Two-year survival of CMV infection was similar in the three kinds of SCT.

CONCLUSIONDetection of CMV DNA in plasma by real time PCR appears to be effective for the diagnosis and surveillance of CMV infection after HSCT. It may help to initiate antiviral therapy and reduce the incidence of CMV disease in the patients with high risk of CMV infection.

OBJECTIVETo study the diagnostic value of human cytomegalovirus (HCMV) late mRNA detection in active intrauterine infection.

METHODSThe HCMV late mRNA in peripheral blood of 42 HCMV IgM positive pregnant women and their fetal attachments (such as chorionic villi, amniotic fluid, umbilical blood and placenta) were detected by reverse transcription polymerase chain reaction (RT-PCR).

RESULTSLate mRNA was detected in 23 of 42 HCMV IgM positive cases, a rate of 54.3%. Fetal appendages in 13 cases of late mRNA positive mothers were also tested, of which 7 were positive, with a vertical transmission rate of 53.8%. In 12 late mRNA negative mothers, only 1 case of fetal appendages tested was positive, with a vertical transmission rate of 8.3%. There was significant difference between the transmission rates of these two groups.

CONCLUSIONSPositive results of HCMV IgM cannot accurately reflect the activity of HCMV at the time of testing. However, the activity of HCMV is closely related to the mother-fetus vertical transmission rate. As an indicator of active HCMV infection, late mRNA can not only reflect the mother-fetus transmission rate during active HCMV infection, but also provide some information about HCMV activity in fetal tissue.
