Abstract
Human viral oncogenesis is a complex phenomenon and a major contributor to the global cancer burden. Several recent findings revealed cellular and molecular pathways that promote the development and initiation of malignancy when viruses cause an infection. Even, antiviral treatment has become an approach to eliminate the viral infections and prevent the activation of oncogenesis. Therefore, for a better understanding, the molecular pathogenesis of various oncogenic viruses like, hepatitis virus, human immunodeficiency viral (HIV), human papillomavirus (HPV), herpes simplex virus (HSV), and Epstein-Barr virus (EBV), could be explored, especially, to expand many potent antivirals that may escalate the apoptosis of infected malignant cells while sparing normal and healthy ones. Moreover, contemporary therapies, such as engineered antibodies antiviral agents targeting signaling pathways and cell biomarkers, could inhibit viral oncogenesis. This review elaborates the recent advancements in both natural and synthetic antivirals to control viral oncogenesis. The study also highlights the challenges and future perspectives of using antivirals in viral oncogenesis.

Abstract
Background:
Human herpesvirus 8 (HHV-8) is considered as the etiological agent of Kaposi’s sarcoma (KS). In people living with human immunodeficiency virus (HIV) (PLHIV), KS defines acquired immunodeficiency syndrome (AIDS). Previous study found that HIV-positive individuals were more likely to be HHV-8 seropositive than HIV-negative individuals. Reports regarding the presence of HHV-8 and HIV co-infection in Indonesia is severely limited.
Aim:
This study aimed to identify HHV-8 infection among HIV-positive individuals in Bali, Indonesia.
Materials and Methods:
Forty three plasma samples were collected from 16 antiretroviral therapy (ART) naive and 27 ART-experienced individuals residing in Buleleng Regency, Bali, Indonesia. Detection of HHV-8 antigen was performed by using ELISA method. The Fisher's Exact test and the Spearman correlation test would be used to analysed data accordingly.
Results:
Seven samples (7/43, 16.3%), one of ART-naive individual (1/16, 6.25%) and six of ART-experienced individuals (6/27, 22.2%), were tested positive for HHV-8 antigen. Human herpesvirus 8 infection was correlated neither to sex (p=1.000) and age (p=0.716), nor to ART status (p=0.178) and length of ART (p=0.465).
Conclusion:
This study indicates the emergence of HHV-8 infection among HIV-positive individuals residing in Bali, Indonesia. Sufficient diagnosis of HHV-8 should be considered for all HIV-positive individuals in order to deliver appropriate treatment. Extensive researches is suggested to be conducted in more regions of Indonesia in order to determine the magnitude of HHV-8 infection among HIV-positive individuals.

Abstract
Background Oral lesions are considered to be early clinical signs which may predict the progression of patients with acquired immune deficiency syndrome (AIDS). Due to the lack of a comprehensive study that includes oral lesions in people with AIDS, the global prevalence of oral lesions in people with AIDS was estimated by combining preliminary studies' results using meta-analysis.Material and methods Databases including PubMed, Science Direct and Scopus were searched using keywords as 'HIV', 'AIDS', 'oral candidiasis', 'Kaposi Sarcoma', 'LinearGingival Erythema' and OR operators, AND and NOT. After the elimination of duplicate documents, articles that met the inclusion criteria were selected. Quality assessment was performed based on the Newcastle-Ottawa Scale. After combining the results of preliminary studies, an overall estimate of each lesion was reported. Ninety-five studies met the criteria for inclusion in this meta-analysis.Results The global prevalence of 21 oral lesions in HIV-infected patients was estimated. The overall prevalence of oral candidiasis, pseudomembranous candidiasis, oral hairy leukoplakia, Kaposi sarcoma and erythematous candidiasis was as follows: 35% (95% CI: 28-42), 19% (95% CI: 15-22), 12% (95% CI: 11-14), 5% (95% CI: 4-6) and 18% (95% CI: 14-22).Conclusion The present meta-analysis showed that oral lesions have a high prevalence in patients with AIDS. Dentists should consider that the clinical appearance of the oral cavity reflects the overall systemic health of the patient. As such, oral lesions may be linked to underlying immunosuppression caused by AIDS.

Abstract
Background Human herpesvirus 8 (HHV-8) infection is etiologically related to Kaposi’s sarcoma. Antibodies directed against HHV-8 can be detected in 80-95% of HIV-seropositive patients with KS. HHV-8 serological tests have been done in several countries in Southeast Asia such as Malaysia, and Thailand however no serological data is available in Indonesia. This study was to examine the presence of HHV- 8 antibodies in HIV-positive patients in Surabaya, Indonesia. Material and methods Ninety-one serum samples were collected from HIVpositive patients in Surabaya, Indonesia. Human immunodeficiency virus-positive serum samples were collected from 10 homosexual men, 25 intravenous drug users (IVDUs) and 56 heterosexuals. Serums were then tested for the presence of HHV-8 antibody by using sandwich ELISA (Abbexa Ltd, Cambridge, UK). Results The total of 91 HIV-infected were testing with antibodies to HHV-8 using enzyme-linked immunosorbent assay. Antibodies of HHV-8 were detected in 7/91 (7.7%) of the samples. According to a gender, six men (85.7%) and a women (14.3%) were positive of HHV-8 antibodies. No correlation regarding the gender and age from this study. The antibodies of HHV-8 was detected among intravenous drug users (IVDUs) men 5/7 (42.8%) and 2/7 (28.6%) from homosexual and heterosexual, respectively. Conclusion This study found the presence of HHV-8 antibodies in 7.7% of patients in Surabaya, Indonesia. This finding was higher more than Southeast Asian countries. The patients with a positive result could suggest measures to prevent HHV-8 infection.

Abstract
Objectives Human herpesvirus 8 (HHV-8) is transmissible and causes Kaposi’s sarcoma and
other malignancies. This study analyzed the seroepidemiology and phylogeny
of HHV-8 among 515 injection drug users (IDUs) and 229 men who have sex with
men (MSM) in Taiwan. Methods Blood and peripheral mononuclear cells were analyzed for HHV-8 seroprevalence
using enzyme-linked immunosorbent and immunofluorescence assays. Viral loads
were measured using a real-time PCR assay. Phylogenetic analysis of the K1
gene was performed using nested PCR and DNA sequencing. Results HHV-8 infection rate was higher in MSM (24.9%) than in IDUs (3.8%). The rate
of HHV-8 infection was higher in HIV-1-positive patients (32.8%, MSM; 5.5%,
IDUs) than in HIV-1 negative patients. HHV-8 load was not significantly
different between HHV-8 seropositive and seronegative patients. HHV-8
genotypes C and A variants were detected at frequencies of 80% and 20%,
respectively, among IDUs; and genotypes C, D, E, and A were detected at
frequencies of 55.6%, 11.1%, 11.1%, and 5.6%, respectively, among MSM.
Variants of K1 amino acid residues 54–84 were detected in most IDUs and
MSM. Conclusions HHV-8 prevalence was significantly higher among MSM than among IDUs.
Evolution of the K1 gene occurred in HHV-8 variants of IDUs and MSM.

Abstract
Men who have sex with men (MSM) were highly vulnerable to HIV/AIDS and Human herpes virus 8 (HHV8), while the epidemiologic features of HHV8 among MSM remain obscure. We therefore performed a systematic review and meta-analysis to assess the burden of HHV8 in MSM. Electronic databases were searched for publications on HHV8 epidemiologic characteristics among MSM. Random-effect meta-analysis was applied to combine the HHV8 seroprevalence in MSM and odds ratios (ORs) for associated risk factors. Meta-regression and stratified analyses were performed to detect the potential sources of heterogeneity. The pooled HHV8 seroprevalence in MSM was 33.0% (95%CI 29.2%-37.1%). Significant factors associated with HHV8 included HIV (OR 3.70, 95%CI 2.93-4.67), STDs (OR 2.32, 95%CI 1.82-2.97), and high risk sexual behaviors (OR 1.50, 95%CI 1.17-1.92). Race (OR 1.44, 95%CI 0.94-2.12) and multiple sexual partners (OR 1.61, 95%CI 0.95-2.72) were also associated with HHV8 (P < 0.10). We found no significant association between IDU and HHV8 (OR 1.44, 95%CI 0.06-32.47). HHV8 is highly prevalent among MSM and the high risk behaviors may facilitate the transmission of this virus. This situation could be of significant public health importance, especially in the context of HIV coinfection.

Abstract
Background Kaposi’s sarcoma (KS) remains the most common malignancy among HIV-infected patients. Human herpesvirus type-8 (HHV-8) is regarded as the infectious etiological agent of Kaposi’s sarcoma (KSHV). Diagnostic procedures associated with KSHV are not routinely performed in HIV-infected subjects. Objectives The main objective of this study is to obtain information on KSHV epidemiology in Iranian HIV-infected individuals. Patients and Methods In the present cross-sectional study, 109 patients with established HIV infection, who visited a governmental and referral center for HIV screening in Tehran (Tehran west health center (TWHC)) between May 2014 and July 2015 were enrolled according to the convenience sample strategy. After peripheral blood collection, isolation of plasma and peripheral blood mononuclear cell (PBMC) compartments, DNA extraction was performed. KSHV DNA was analyzed by nested polymerase chain reaction (nested PCR) using primers from ORF-26 (virus minor capsid). Results Among all 109 HIV-infected patients, 67 (61.5%) were male, with an age range of 2 - 64 years (mean ± standard deviation 35.8 ± 13.3). KSHV DNA was found in PBMC and plasma samples of six (5.5%) and four (3.6%) patients, respectively. Conclusions This study revealed a considerable prevalence of KSHV DNA, during latent and lytic phases, among HIV-infected patients. Risk factors for KSHV infection acquisition and concurrent. 0+infection with HIV were also evaluated. Diagnosis of KSHV in the group could be helpful for prognosis of Kaposi’s sarcoma and clinical management.

Abstract
Kaposi's sarcoma-associated herpesvirus (KSHV) may be transmitted via sexual contacts, but limited information is available on KSHV infection status among sexually transmitted infection (STI) patients in China. The main objective of the present study was to determine the KSHV seroprevalence and its risk factors among male STI patients. A cross-sectional survey was conducted in three prefectures of Anhui province, China, between June and September 2013. A total of 1,600 male patients who visited an STI clinic were invited, and 1,372 participated in the study. Data were abstracted from the medical records for all the patients. Blood samples were collected and tested for antibodies to KSHV, HIV, HCV, and syphilis. Factors associated with KSHV seropositivity were examined using multivariable logistic regression analysis. The overall prevalence of KSHV, HIV, HCV, and syphilis was 13.3%, 0.7%, 0.6%, and 12.5%, respectively. After adjusting for potential confounders, KSHV infection was significantly associated with ever having anal sex with men (19 out of 30 males, OR: 8.64, 95%CI: 1.92-38.79) and HIV infection (six out of nine HIV-positive individuals, OR: 8.39, 95%CI: 1.80-39.04). There were no significant associations of KSHV infection with drug use, heterosexual sex behaviors, syphilis, and HCV. Our finding has shown that a relatively moderate prevalence of KSHV was found among male STI patients. While an increased risk for KSHV infection was observed among participants with homosexual contacts. Routine KSHV testing is recommended for male individuals attending STI clinics.

Abstract
BACKGROUND The Epstein-Barr virus (EBV) and Kaposi's sarcoma associated herpesvirus (KSHV) are consistently associated with lymphoproliferative diseases and cancers in humans, notably in patients with HIV. AIMS Our aim was to evaluate whether EBV and/or KSHV viral loads regularly assessed in peripheral blood mononuclear cells (PBMC) correlate with clinical or laboratorial parameters retrieved for patients living with HIV. METHODS This was a longitudinal study with a cohort of 157 HIV positive patients attending an academic HIV outpatient clinic in São Paulo State, Brazil. For each patient, up to four blood samples were collected over a 1 year clinical follow-up: on enrolment into the study, and after 4, 8 and 12 months. Total DNA was extracted from PBMC, and EBV and KSHV viral loads were assessed by real time quantitative PCR. RESULTS Higher viral loads for EBV were significantly associated with high HIV viraemia, a greater number of circulating T CD8+ cells and lack of virological response to the antiretroviral treatment. KSHV viral load was undetectable in virtually all samples. CONCLUSIONS EBV viral load in PBMC correlated with the number of circulating T CD8+ lymphocytes and the response to the antiretroviral therapy in HIV infected patients. In contrast, KSHV was undetectable in PBMC, presumably an effect of the antiretroviral treatment. Therefore, either KSHV infection in the population studied was absent or viral load in PBMC was beyond the analytical limit of the assay.

Abstract
Kaposi's sarcoma-associated herpesvirus (KSHV)/human herpesvirus 8 is a tumorigenic rhadinovirus that is associated with all forms of Kaposi's sarcoma. Current serological detection of KSHV is based on enzyme-linked immunosorbent or immunofluorescence assays that suffer from a variety of problems, including the lack of defined standards for test comparison. While KSHV is the only known human rhadinovirus, two lineages of KSHV-like rhadinoviruses are found in Old World primates: the RV1 lineage includes KSHV and retroperitoneal fibromatosis herpesvirus (RFHV) in macaques, and the RV2 lineage includes RRV and MneRV2 from different macaque species. To develop animal models of KSHV-associated diseases, we developed quantitative multiplex bead-based serological assays to detect antibodies against rhadinovirus antigens. Proteins from KSHV (RV1) and MneRV2 (RV2) virions were coupled to spectrally distinct fluorescent beads and used in Luminex flow cytometry-based assays to detect immune responses in macaques. Both assays showed large dynamic ranges with high levels of seroreactivity to both KSHV and MneRV2 proteins. A large set of macaque serum samples from the Washington National Primate Research Center was screened, and most of the samples (82%) were positive in both assays, consistent with the high level of RV1-RV2 coinfection detected by PCR. The macaque sera showed broad, variable, and unique serological responses to the different viral antigens, allowing an initial seroprevalence to be determined for the macaque viruses. The Luminex assays offer a novel multiplexed approach to assess rhadinovirus infection patterns in both humans and nonhuman primates. This will help advance our understanding of rhadinovirus biology and associated host immunological responses.

Abstract
OBJECTIVE To describe the effect of HAART on Kaposi sarcoma herpes virus (KSHV) antibody response and viremia among HIV-positive MSM. DESIGN A follow-up study of 272 HIV-positive MSM (including 22 with Kaposi sarcoma) who first initiated HAART between January 1996 and July 2004 in the Swiss HIV Cohort Study. METHODS For each individual, two serum samples, one at HAART initiation and another 24 months later, were tested for latent and lytic KSHV antibodies using immunofluorescence assays, and for KSHV viremia using PCR. Factors associated with changes in KSHV antibody titers and viremia were evaluated. RESULTS At HAART initiation, 69.1 and 75.0% of patients were seropositive to latent and lytic KSHV antibodies, respectively. Seropositivity was associated with the presence of Kaposi sarcoma, older age, lower CD8 cell count and higher CD4/CD8 ratio. Prevalence of KSHV viremia at HAART initiation was 6.4%, being significantly higher among patients with Kaposi sarcoma (35.0%), and those with HIV viral loads 100 000 copies/ml (11.7%) or higher. At 24-month follow-up, geometric mean titers (GMTs) among KSHV seropositive patients increased and antibody seroprevalence was higher. Having Kaposi sarcoma and/or CD4 cell counts less than 50 cells/microl at HAART initiation was associated both with higher probability for antibody titers to increase (including seroconversion) and larger increases in GMTs. Only one of 17 viremic patients at HAART initiation had viremia at 24-month follow-up. CONCLUSION HAART increases KSHV-specific humoral immune response and clearance of viremia among HIV-infected MSM, consistent with the dramatic protection offered by HAART against Kaposi sarcoma.

Abstract
Only limited epidemiological data, pertaining to the prevalence of common persistent viruses has been reported in Ghana. This study was conducted to determine the prevalence of persistent viruses in individuals with untreated HIV-1 infection and uninfected blood donors. Paired plasma and cellular samples from HIV-negative blood donors, asymptomatic HIV and symptomatic/AIDS cohorts were screened by multiplex PCR then qPCR for parvovirus B19 (B19V), hepatitis B virus (HBV), GB virus-C (GBV-C), cytomegalovirus (CMV), Epstein-Barr virus (EBV), human herpesvirus-8 (HHV-8) and varicella-zoster virus (VZV). IgG antibodies specific to each target virus were tested to determine exposure rates. No evidence of viraemia was found for B19V and VZV in any group. Prevalence of GBV-C plasma viraemia was significantly higher in asymptomatic and symptomatic HIV infection (16.7%) and (16.2%) than in blood donors (4%) P < 0.005. Occult HBV infection was significantly more frequent in symptomatic HIV infection (10.9%) compared to asymptomatic HIV (3.6%) and blood donors (1.6%) P < 0.005. Although there was a high background of EBV viraemia in cellular fractions of blood donors (8.3%), it was significantly higher in asymptomatic (44.6%) and symptomatic HIV (14.6%) P < 0.0001. For CMV, the significantly increased prevalence of viraemia was only observed in the plasma fraction of the symptomatic HIV-1/AIDS patients (7.6%) compared to asymptomatic individuals (1.8%) and blood donors (0.8%) P < or = 0.001. The background seroprevalence in blood donors was high for B19V (> or =64%), HBV (> or =70%), CMV and EBV (> or =90%) and was significantly increased in HIV infections for HBV, CMV, VZV (symptomatic HIV), and HHV-8 (asymptomatic and symptomatic HIV).

Abstract
Kaposi's sarcoma occurs at high incidence among Zambian adults and children, but there is a paucity of data on human herpesvirus 8 (HHV-8) incidence and routes of infection, especially in children. Between 1998 and 2004, the authors conducted a prospective study of viral transmission in a cohort of 684 children in Lusaka, Zambia, to estimate the annual incidence of HHV-8 from birth through 48 months of age. Maternal and pediatric human immunodeficiency virus type 1 (HIV-1) infection status was also determined. The results, based on 1,532 child-years of follow-up, showed that HHV-8 seroconversion occurs early in life. The incidence rate of HHV-8 seroconversion was 13.8 infections per 100 child-years by 48 months of age. HIV-1-infected children were at substantially higher risk for HHV-8 seroconversion (adjusted hazard ratio = 4.60, 95% confidence interval: 2.93, 7.22). Maternal HIV-1 and HHV-8 infection status were not independently associated with risk of HHV-8 seroconversion in the child. HHV-8 antibody titers in children followed at all consecutive time points revealed sero-reversion of HHV-8 antibodies, with undetectable titers in some children at one or more time points after seroconversion. These results demonstrate that cross-sectional serologic screening probably underestimates true HHV-8 seroprevalence in young Zambian children because of fluctuations in detectable antibody titers.

Abstract
In common with latent viruses such as herpesviruses, parvovirus B19, HBV and GBV-C are contained successfully by the immune response and persist in the host. When immune control breaks down, reactivation of both latent and persistent viruses occurs. Two multiplex assays were developed (B19, HBV, HHV-8), (EBV, CMV, VZV) for blood screening, and tested on blood donor samples from Ghana to determine baseline prevalence of viraemia in immunocompetent persons. Single-virus real-time quantitative PCR (qPCR) assays were optimised for viral load determination of positive initial screening. The qPCR method utilised was absolute quantification with external standards. Multiplex and single-virus qPCR assays had similar sensitivity, except for the B19 assay in which sensitivity was 100-fold lower. Assays were optimised for reproducibility and repeatability, with R(2) of 0.9 being obtained for most assays. With the exception of B19 and CMV, assays had 100% detection limit ranging between 10(1) and 10(2) copies, IU or arbitrary units under single-virus and multiplex assay conditions. The prevalence of viraemia was 1.6% HBV (0.8% DNA+/HBsAg-, 0.8% DNA+/HBsAg+), 0.8% parvovirus B19, and 3.3% GBV-C viraemia in the plasma fraction. The prevalence of four herpesviruses was 1.0% HHV-8, 0.85% CMV, and 8.3% EBV, and no detectable VZV viraemia.

Abstract
The purpose of this study was to assess the qualitative single and multiple herpes virus DNAemia in the peripheral blood leukocytes (PBLs) of HIV-1-positive patients and its impact on the response to highly active antiretroviral therapy (HAART) and immune reconstitution. All (163) HIV-1-positive patients attending "Syngros AIDS Referral Center" from November 2000 to February 2001 were recruited. CMV, HSV-1, HSV-2, EBV, and HHV-8 DNA were detected in PBLs by polymerase chain reaction (PCR). Patients' follow-up comprised regular measurements of CD4(+) T cell count and HIV-1 viral load (VL) for an average period of 21 months. Immune reconstitution was defined as an increase in the CD4 T cell count by above 200 cells/micro l, while response to HAART was defined as a decrease in HIV-1 VL to undetectable levels. Single and multiple herpetic DNAemia in PBLs was found to be significantly higher in HIV-1-positive patients compared to healthy controls (p < 0.02) for all the viruses detected apart from HSV-2, which was not detected in the PBLs of either population. Concurrent CMV and EBV DNAemia significantly correlates with a delay in the response to HAART (p = 0.033) in treatment-naive patients. Untreated patients with a CD4(+) T cell count <200 cells/micro l, and with either CMV or EBV DNAemia, presented a delayed increase in the CD4 count after initiation of HAART (p = 0.035 and p = 0.037 respectively), while multiple herpetic DNAemia in the above patients was borderline associated with immune reconstitution (p = 0.068). Conclusively, CMV and EBV DNAemia may be poor prognostic factors for the response to HAART in treatment-naive HIV-1 patients.

Abstract
Human herpesvirus 8 (HHV-8) antibody tests vary in sensitivity and specificity, depending on the population tested and on the type of assay. In this study, we evaluated the sensitivity and specificity of two peptide enzyme immunoassays using a multiple antigenic peptide (PK8.1-MAP) or a chimeric peptide (PK8.1-orf65) as the antigens and determined the HHV-8 seroprevalence in different Argentine populations using an immunofluorescence assay (IFA) as reference. For analysis, when either or both of the peptide EIAs were positive, the specimen was considered positive (PEIA). We estimated the sensitivity and specificity of PEIA to be 97% using Kaposi's sarcoma (KS) patients and healthy individuals as positive and negative controls respectively. Then, we expanded the control groups to include IFA positive men who have sex with men (MSM) and IFA negative blood donors. The sensitivity decreased to 83% but specificity remained high at 98%. Concordance between PEIA and IFA was 77% for 1/40 IFA titers and increased to 90% for titers >or=1/160. Seroprevalences for HHV-8 performed in the HIV positive MSM were (IFA 73.1%; PEIA55.2%); heterosexuals (52.5%, 22.2%), which includes injecting drug users (IDU) (54.0%, 32.4%) and non-IDU (51.6%, 16.1%). The inclusion of non-KS HHV-8 IFA positive individuals to the positive controls may be a substantial improvement towards the realistic assessment of assay sensitivity. These peptide EIAs can be used for trends in populations with high probability of being HHV-8 infected and negative results should be confirmed by IFA. IFA test is still the most suitable test for populations with low probabilities of being infected.

Abstract
Patients who have common variable immunodeficiency (CVID) and granulomatous/lymphocytic interstitial lung disease (GLILD) are at high risk for early mortality and B cell lymphomas. Infection with human herpes virus type 8 (HHV8), a B cell lymphotrophic virus, is linked to lymphoproliferative disorders in people who have secondary immunodeficiencies. Therefore, we determined the prevalence of HHV8 infection in CVID patients with GLILD. Genomic DNA isolated from peripheral blood mononuclear cells was screened by nested- and real time-quantitative PCR (QRT-PCR) for the presence of HHV8 genome. It was positive in 6/9 CVID patients with GLILD (CVID-GLILD), 1/21 CVID patients without GLILD (CVID-control), and no patients receiving intravenous gamma globulin (n = 13) or normal blood donors (n = 20). Immunohistochemistry (IHC) demonstrated expression of the latency-associated nuclear antigen-1 (LANA-1) in the biopsies of the lung, liver, and bone marrow of four patients with CVID-GLILD. One CVID-GLILD patient developed a B cell lymphoma during the course of the study. QRT-PCR demonstrated high copy number of HHV8 genome and IHC showed diffuse staining for LANA-1 in the malignant lymph node. HHV8 infection may be an important factor in the pathogenesis of the interstitial lung disease and lymphoproliferative disorders in patients with CVID.
