Cytomegalovirus(CMV) disease is a major cause of morbidity and mortality in immunocompromised patients. CMV enteritis should be considered when nausea and vomiting continue 3 to 4 weeks after bone marrow transplantation(BMT). The treatment of CMV enteritis is not well established. We report a CMV duodenitis patient following allogenic bone marrow transplantation. The patient had prolonged nausea and vomiting for 5 weeks after bone marrow transplantation and CMV duodenitis was diagnosed by the gastroduodenoscopic mucosal biopsy which showed cytomegalic cells. Ganciclovir treatment for 3 weeks resulted in the resolution of symptoms and promoted healing of the lesion. The patient was free of CMV infection until 288 days after allogenic BMT without maintenance ganciclovir 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.

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.

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.

BACKGROUND/AIMS: The frequencies of opportunistic diseases (ODs) vary across countries based on genetic, environmental, and social differences. The Korean HIV/AIDS cohort study was initiated in 2006 to promote research on human immunodeficiency virus (HIV) infection in Korea, and to provide a logistical network to support multicenter projects on epidemiological, clinical, and laboratory aspects of HIV infection. This study evaluated the prevalence of ODs among HIV-infected patients in the era of highly active antiretroviral therapy, and the risk factors associated with ODs. METHODS: The study enrolled 1,086 HIV-infected patients from 19 hospitals. This study examined the baseline data of the HIV/AIDS Korean cohort study at the time of enrollment from December 2006 to July 2013. RESULTS: Candidiasis was the most prevalent opportunistic infection (n = 176, 16.2%), followed by Mycobacterium tuberculosis infection (n = 120, 10.9%), Pneumocystis jirovecii pneumonia (n = 121, 11.0%), cytomegalovirus infection (n = 52, 4.7%), and herpes zoster (n = 44, 4.0%). The prevalence rates of Kaposi’s sarcoma (n = 8, 0.7%) and toxoplasmosis (n = 4, 0.4%) were very low compared with other countries. The risk factors for ODs were a low CD4 T cell count at the time of HIV diagnosis (odds ratio [OR], 1.01; p < 0.01), current smoking (OR, 2.27; p = 0.01), current alcohol use (OR, 2.57; p = 0.04), and a history of tuberculosis (OR, 5.23; p < 0.01). CONCLUSIONS: Using recent Korean nationwide data, this study demonstrated that an important predictor of ODs was a low CD4 T cell count at the time of HIV diagnosis. Tuberculosis remains one of the most important ODs in HIV-infected patients in Korea.

The study was purposed to investigate diagnostic value of late-mRNA detection by nucleic acid sequence-based amplification (NASBA) technique for human cytomegalovirus (HCMV) infection of the recipients after allogeneic peripheral blood stem cell transplantation (allo-PBSCT) and to evaluate the clinical significance for guiding antiviral therapy. 352 samples were collected from 128 transplant patients after allo-PBSCT. A molecular biological diagnostic technique--NASBA was used to detect human cytomegalovirus (HCMV) late mRNA encoding the viral structural protein PP67 (UL65) expression in peripheral blood of recipients after allo-PBSCT, and the detected results were compared with HCMV DNA detection by PCR. The sensitivity, specificity and early diagnostic value of HCMV mRNA detection for HCMV disease were evaluated. The results showed that out of 352 detected blood specimens from 84 patients 183 specimens (51.99%) were positive of HCMV DNA by PCR, 105 specimens (29.83%) were positive of HCMV mRNA by NASBA. 45 patients were infected by HCMV. The sensitivity and specificity of HCMV DNA and HCMV mRNA for detecting HCMV disease were 95.56% (43/45), 93.33% (42/45) and 60.24% (50/83), 97.59% (81/83). The results of specificity showed significant difference between two groups of HCMV mRNA and HCMV DNA (P < 0.05). It is concluded that the detection of late-mRNA of HCMV by NASBA technique is rapid, sensitive and specific detection for HCMV active infection. The detected result correlates with clinical symptoms. It can monitor HCMV infection of allo-PBSCT transplanted recipients and provide indication to antiviral therapy.

BACKGROUNDTo detect quantitatively HCMV DNA in peripheral blood leukocytes to monitor the status of HCMV infection, evaluate the effectiveness of antiviral treatment with ganciclovir (GCV) combined with intravenous immunoglobulin (IVIG) and find out the relationship among the HCMV DNA levels, the state of infection and the clinical outcome.The long-term goal of the study was to establish a molecular diagnostic standard for HCMV infection in children.

METHODS45 cases of suspected HCMV-infected children were examined by PCR, ELISA and fluorescent quantitative (FQ)-PCR, respectively. Twenty five HCMV hepatitis cases of the 45 were randomly assigned to a treated group or a control group. Both groups were treated with prednisone, glucurone, Luminal and Xiaoyanlidanpian. But the treated group was given with GCV+IVIG in addition. Each infant of the two groups was checked with FQ-PCR at the five time points.

RESULTSThe positive rates of PCR, ELISA and FQ-PCR were 60.00%, 33.33% and 66.67%,their sensitivities were 84.38%, 46.88% and 93.75%, respectively. There was no significant difference in viral DNA copy numbers between the two groups before being treated (P>0.05), but there was significant difference between HCMV hepatitis and normal infants (P<0.001). Although viral load of both groups decreased in both groups, the viral load of the treated group decreased more significantly. The level of HCMV DNA fell to 103 copies/ml at second time point while that of the control group fell to the same level after third time point. The differences between the two groups at each time point were statistically significant (P<0.001). The results of 135 person times testing indicated that 103 copies/ml of FQ-PCR can be taken as a critical value for prediction of active HCMV infection.

CONCLUSIONSFQ-PCR may be one of the effective methods for diagnosis of HCMV disease; it can offer a key index in the diagnosis of HCMV active infection; dynamic detection of HCMV viral load can play a role not only in monitoring antiviral therapy, but also in evaluating the development and prognosis of HCMV disease.
