Abstract
A man in his late 60s with well-controlled HIV underwent an uneventful surgical clipping of an unruptured intracranial aneurism. Postoperatively, he developed fever, seizures and an altered mental status. Cerebrospinal fluid (CSF) showed lymphocytic pleocytosis, high protein count and a positive herpes simplex virus (HSV)-2 PCR. Acyclovir was started. Brain MRI showed right hemisphere T2/FLAIR-weighted anterior temporal cortical and subcortical hyperintensities. After 2 months, he developed psychosis, an upper limb tremor and pyramidal tract dysfunction. A new brain MRI revealed a new right frontal white matter lesion, extending to the corpus callosum. Anti-N-methyl-D-aspartate receptor (NMDAR) antibodies were positive in CSF, while there was no evidence of active HSV infection. Methylprednisolone and IVIg were started, and a significant clinical improvement was achieved.If an unknown inflammatory process occurs after surgery, herpetic encephalitis should be considered, and treatment should be initiated precociously. Since herpetic encephalitis can trigger an anti-NMDAR encephalitis, this autoimmune complication must be considered.

Abstract
BACKGROUND Several co-factors for HPV oncogenesis have been proposed, including co-infection with HSV-2. We assessed the relationship between HSV-2 infection and HPV-related outcomes in quadrivalent HPV-vaccinated (qHPV) women living with HIV (WLWH). METHODS In this multi-site study of immunogenicity and efficacy of the qHPV vaccine in WLWH, visits took place at months -3, 0, 2, 6, 12, 18, 24, and annually thereafter. Participants provided clinical data and cervico-vaginal swabs for HPV DNA detection; baseline serum was tested for HSV-2 type-specific antibodies. We used non-parametric statistics to compare HPV-related outcomes by HSV-2 serostatus and use of anti-HSV medication. RESULTS 151 baseline serum samples underwent HSV-2 testing. At baseline, median age was 39 years, median CD4 count was 500 cells/mm3, and 70% had an HIV viral load of <50 copies/mL. Baseline HSV-2 seroprevalence was 76.2%. HSV-2 seropositivity was associated with increased age (p = 0.006). Controlling for age and median CD4 count, HSV-2 seropositivity was not associated with HPV incidence, persistence, and precancerous lesions. The use of anti-HSV medications was associated with higher odds of HSIL cytology (OR = 3.35, 95% CI = 1.03,11.26) and a greater number of HPV types detected (OR = 1.18, 95% CI = 1.00,1.39). Results were similar in sensitivity analyses using an index value of 3.5. The presence of HSV lesions during the study was not associated with HPV outcomes. CONCLUSIONS HSV-2 seropositivity was common in this cohort of WLWH in Canada but was not associated with multiple measures of HPV incidence, persistence, and precancerous lesions. However, the use of anti-HSV medications was associated with HSIL cytology and number of HPV types detected.

Abstract
BACKGROUND The prevalence of Human Immunodeficiency Virus (HIV) and Herpes Simplex Virus type-2 (HSV-2) infections are high and the programme for Cervical Cancer Screening is weak in Nigeria. OBJECTIVES Prevalence of Herpes Simplex Virus Type-2 co-infection and cervical cytology among HSV-2 co-infected Human Immunodeficiency Virus Sero-positive (HIV+) women on Highly Active Antiretroviral Therapy (HAART) attending Human Immunodeficiency Virus clinic at University of Nigeria Teaching Hospital (UNTH) Ituku/Ozalla Enugu, Nigeria. METHODS A cross-sectional, hospital-based study. Active participants included 105 HIV seropositive women on HAART and104 HIV seronegative (HIV-) women who passed inclusion criteria and signed written informed consent. Each participant was coded with a specific number. A structured questionnaire was used to obtain the socio-demographic and medical history. Serum was obtained for HSV-2 serology test for all participants and HIV screening for HIV-negative participants. Cervical smears were collected for Papanicolaou stains and Immunocytochemistry using anti-P16INKa antibody. RESULTS Prevalence of HSV-2+ was 50.5% among HIV+ women on HAART and 16.3% among HIV- women, Odds Ratios [95% CI]; p-value was 5.21 [2.74-9.94]; p < 0.0001. HIV+ women on HAART co-infected with HSV-2 significantly had more Cervical Lesions, 11.4% compared to HIVwomen uninfected with HSV-2, 4.8%, OR [95% CI]; p-value 4.8 (1.58-14.54); p = 0.006. CONCLUSION The prevalence of HSV-2 was significantly high among HIV+ women on HAART. HSV-2+ co-infection could be an enhancer of Cervical Lesions among HIV+ women on HAART. Hence, anti-herpetic agent introduction and screening for HSV-2 among HIV+ patients are recommended.

Abstract
Background:Understanding the relationship between HIV and SARS-CoV-2 has important public health implications.Objective:To summarize current research on COVID-19 among people with HIV (PWH) as published through 15 July 2021.Methods: We conducted a search of PubMed, Scopus, preprint databases (medRxiv, bioRxiv), and the references of publications found using key terms relevant to COVID-19 ('COVID-19' OR 'SARS-CoV-2' OR 'coronavirus') AND to HIV ('HIV' OR 'Human Immunodeficiency Virus' OR 'AIDS' OR 'Acquired Immunodeficiency Syndrome'). We summarized all articles that reported data or opinions on SARS-CoV-2 and HIV coinfection.Conclusions: Although many initial case series and cohort studies found no increased risk for SARS-CoV-2 infection or severe COVID-19 outcomes among PWH, recent studies have signaled an increased risk for severe COVID-19 disease progression even in the setting of well-controlled HIV. Whether this is due to the increased prevalence of comorbidities in PWH and other social determinants of health is unknown. These conflicting findings highlight the continued need for COVID-19 related research among PWH that addresses COVID-19 disease course as well as exacerbation of existing comorbidities already disproportionately represented among PWH.

Abstract
Background: Recurrent herpes labialis (RHL) is a disorder with serious health and social consequences and which affects most of the adults. However, high degree of research paucity pertaining to its prevalence was observed, especially from India. Objective: The objective of this study was to assess the prevalence of RHL in western Maharashtra. Materials and Methods: In this prospective study, 1368 patients of either sex, satisfying the inclusion criteria, were included in the study after screening 34,560 patients for RHL lesions. Demographic data such as age, gender and risk factors, namely stress, menstruation and common cold, were recorded. Further, data regarding history of itching, fever, malaise and burning on lips followed by vesicles and frequency of lesions and duration were also recorded. After clinical examination site, size and nature of lesion were noted on a clinical pro forma. Results were compared statistically, and P < 0.05 was considered statistically significant. Results: The majority of the patients were in the age group of 30–39 years, with a female predominance (63.89%) (male:female = 0.33:0.59). Stress (43%) was the most common risk factor in the occurrence of RHL, followed by disturbed menstruation cycle (21%). Most of the patients had two episodes of RHL (42.4%), whereas some had just one episode of recurrence (25.4%) in the past 1 year. The most commonly occurring location for RHL was upper lip (47%), especially the left side (19.1%) and right side (18.2%) of the upper lip. The overall prevalence rate of RHL in our study was 3.9%. Conclusion: An established prevalence (3.9%) of RHL occurs among patients in western Maharashtra.

Abstract
Background: Herpes simplex virus (HSV) is a widely distributed human pathogen that is known for its ulcerative lesions at the infection site. HSV can cause persistent infection in the host that is often followed by a period of latency within the neurons. Considering the high rate of HIV infection in South Africa, it is important to assess the seroprevalence of HSV with a focus to determine the epidemiological association between HSV-DNA and HIV-1 in the population. Methods: A total of 44 sera samples were screened for HSV and HIV-1 using the highly sensitive enzyme-linked immunosorbent assay (ELISA). The ELISA positive samples were characterized using polymerase chain reaction (PCR) to confirm the positivity of both viruses and to further differentiate HSV into HSV-1 and -2. Thereafter, the samples were analysed for relatedness using phylogenetic analysis. Results: Of the 44 samples, 36 (81.8%) were positive for HIV-1, while 35 (79.5%) were positive for HSV when screened with ELISA kits. The PCR results, with the use of type specific primers, showed that 4/35 (11.4%) samples were specific for HSV-1 while 30/35 (85.7%) were specific for HSV-2. Statistical analysis performed using the chi-squared goodness-of-fit test showed that there is a significant relationship between HSV-2 and HIV-1 transmission. Conclusions: The prevalence of HSV in the population is high with an increased HSV-2 infection in women. Our study shows that some of the HSV-2 isolates are not related to the clinical isolate SD90e from South Africa, suggesting diversity in HSV-2 viral transmission.

Abstract
Background: Herpes simplex viruses (HSVs) are highly pervasive and show a strong synergistic interaction with human immunodeficiency virus (HIV). High prevalence of HSV type 1 (HSV-1) has been reported in Africa with a prevalence rate of 20-80% in women and 10-50% in men. Studies on the prevalence of HSV in South Africa are few considering the rate of HIV infection in the country. Our focus was to determine the molecular prevalence of HSV-DNA in HIV-1 sera. Methods: In total, 44 convenience samples were screened for HSV and HIV-1 using the highly sensitive enzyme-linked immunosorbent assay (ELISA). The ELISA positive samples were characterized using polymerase chain reaction (PCR) to confirm the positivity of both viruses and to further differentiate HSV into HSV-1 and -2. Thereafter, the samples were analysed for relatedness using phylogenetic analysis. Results: Of 44 samples, 36 (81.8%) were positive for HIV-1, while 35 (79.5%) were positive for HSV when screened with ELISA kits. The results of PCR with type specific primers showed that 4/35 (11.4%) samples were specific for HSV-1 while 30/35 (85.7%) were specific for HSV-2. Statistical analysis performed using chi-squared goodness-of-fit test showed that there is a significant relationship between HSV-2 and HIV-1 transmission. Conclusions: High prevalence of HSV-2 recorded in HIV-1 sera corroborate with similar studies conducted within different cohorts in the continent. SPSS Pearson's chi-squared test established that there is a significant relationship between HSV-2 and HIV-1 transmission.

Abstract
BACKGROUND Herpes simplex virus type 2 (HSV-2) is the most common cause of genital herpes (GH), but genital infection by herpes simplex virus type 1 (HSV-1) is increasing. The aim of this study was to analyze and compare epidemiological characteristics of patients with GH. METHODS Retrospective study conducted from January 2004 to December 2015 in patients with GH attended at two Sexually Transmitted Diseases (STDs) medical consultation of Bilbao-Basurto Integrated Health Organisation in Northern Spain. Patient's medical history was reviewed and data of interest was analyzed. RESULTS One thousand three patients (524 male and 479 female) were reviewed. HSV-2 was detected in 74%. The proportion of HSV-1 increased during the study period, significantly in men (28% in 2004-2007 vs. 50% in 2012-2015). More female than male had HSV-1 infection (56% vs. 44%). The proportion of primary infection was higher among HSV-1 compared to HSV-2 (79% vs. 21%). Among the patients with HSV-1, primary infection was higher among men (86%) and in younger than 30 years. Recurrent GH was higher among HSV-2 infections (63%). In a multivariate model older age, geographic origin outside Spain, recurrent infection, prior contact with a partner's genital herpetic lesions, previous N. gonorrhoeae infection and prostitution were significantly associated with HSV-2 infection. CONCLUSIONS HSV-2 was the most common causative agent of GH, but the proportion of HSV-1 increased. Overall, antecedent of STD and sexual risk behaviors were more frequent in patients with genital HSV-2 infection.

Abstract
For millions of years, microbiota residing within us, including those in the oral cavity, coexisted in a harmonious symbiotic fashion that provided a quintessential foundation for human health. It is now clear that disruption of such a healthy relationship leading to microbial dysbiosis causes a wide array of infections, ranging from localized, mild, superficial infections to deep, disseminated life-threatening diseases. With recent advances in research, diagnostics, and improved surveillance we are witnessing an array of emerging and re-emerging oral infections and orofacial manifestations of systemic infections. Orofacial infections may cause significant discomfort to the patients and unnecessary economic burden. Thus, the early recognition of such infections is paramount for holistic patient management, and oral clinicians have a critical role in recognizing, diagnosing, managing, and preventing either new or old orofacial infections. This paper aims to provide an update on current understanding of well-established and emerging viral, bacterial, and fungal infections manifesting in the human oral cavity.

Abstract
A source of comprehensive information on the prevalence of herpes simplex virus type 1 and 2 (HSV-1 and HSV-2) can help researchers and policymakers address HSV related burden in the society. At the moment, this is not readily available. This study aims to fill this gap by attempting to estimate the seroprevalence of HSV-1 and HSV-2 infections in Nigeria on the basis of published data. A systematic review and meta-analysis including cross-sectional studies on HSV-1 and HSV-2 in Nigeria was conducted. Electronic databases including PubMed/MEDLINE, CENTRAL, African Journals Online (AJOL), ScienceDirect, WHO-Afro Library, WHO-IRIS and African Index Medicus were searched for English Language publications on HSV-1 and HSV-2. Seven relevant publications were identified. Seroprevalence measures of 3 and 23 for HSV-1 and HSV-2, respectively, were extracted. The pooled mean seroprevalences for HSV-1 and HSV-2 were 74.0% (37.4-99.4%) and 63.4% (56.1-70.4%) respectively. The mean seroprevalence of HSV-1 was higher among females, 82.4% (n = 509, CI, 36.6-100.0%), than males, 54.5% (n = 198, CI, 47.6-61.4%). The mean seroprevalence of HSV-2 were 51.8% (n = 1414, CI: 39.4-64.0%) and 86.5% (n = 162, CI: 80.8-91.3%) among healthy and clinical populations, respectively. The study was limited by the paucity of quality studies, variations in diagnostic methods and high heterogeneity in seroprevalence estimates. In conclusion, the seroprevalence of HSV-1 and HSV-2 remain high in Nigeria. Large and representative national epidemiological surveys covering all regions and specific groups are recommended.

Abstract
Antiretroviral therapy (ART) has revolutionized the treatment and prognosis of people living with HIV (PLHIV). With increased survival and improved overall health, PLHIV are experiencing dermatologic issues both specific to HIV and common to the general population. In this new era of ART, it is crucial for dermatologists to have a strong understanding of the broad range of cutaneous disease and treatment options in this unique population. In this review, we outline the most common skin diseases in PLHIV, including HIV-associated malignancies, inflammatory conditions, and infections, and focus on the role of ART in altering epidemiology, clinical features, diagnosis, and treatment of cutaneous conditions.

Abstract
OBJECTIVES This study aimed to provide identification criteria for men who have sex with men (MSM), estimate the prevalence of MSM behavior, and compare sociodemographics and sexually transmitted disease risk behaviors between non-MSM and MSM groups using data from a nationally representative, population-based survey. METHODS Using data from men aged 18 to 59 years who took part in the National Health and Nutrition Examination Survey (NHANES), 1999 to 2014, detailed criteria were developed to estimate MSM behavior-at least one lifetime same-sex partner (MSM-ever), at least one same-sex partner in the past 12 months (MSM-current), and at least one lifetime and zero same-sex partners in the past 12 months (MSM-past). RESULTS The estimated prevalence of MSM-ever was 5.5%-of these, 52.4% were MSM-current and 47.1% were MSM-past. Furthermore, MSM-ever are a nonhomogenous subpopulation, for example, 70.4% of MSM-current identified as homosexual and 71.2% of MSM-past identified as heterosexual (P < 0.001). CONCLUSIONS The prevalence of MSM behavior identified here is similar to other published estimates. This is also the first article, to our knowledge, to use National Health and Nutrition Examination Survey data to compare MSM by 2 recall periods (recent vs. lifetime) of last same-sex sexual behavior.

Abstract
BACKGROUND Herpes simplex virus type 2 (HSV-2) is a common infection in human immunodeficiency virus (HIV) patients and may accelerate HIV progression by rising HIV viral load and decreasing CD4 count. However, the available data regarding the influence of HSV-2 seropositivity on HIV progression in HIV individuals are inconclusive. Therefore, we aimed to determine HSV-2 seroprevalence in naïve HIV patients and normal controls and also investigate the relation of HIV viral load and CD4 count with HSV-2 seropositivity. Subsequently, we investigated the association of HSV-2 serostatus with changing in CD4 count and HIV viral load in our subjects, after one year follow-up. METHODS In this study, 116 naïve HIV patients and 85 healthy controls from Tehran, Iran were enrolled. HSV-2 IgG antibody was detected by ELISA. CD4 count was determined by flowcytometry, and serum HIV RNA copy numbers were determined using real-time PCR. RESULTS The prevalence of HSV-2 IgG was 18.1% in naïve HIV patients and 0% in the control group (P=0.000). HSV-2 seroconversion was observed in 2.43% of HIV patients after one year. There was no significant difference regarding HSV-2 serostatus with CD4 count and HIV RNA viral load in our study cohort at baseline and after one year. CONCLUSION Our results revealed that the prevalence and incidence of HSV-2 infection are low in our HIV cases, and it is negligible in control group. However, it seems that HIV/HSV2 co-infection has no role on HIV infection acceleration.

Abstract
This study shows the relative quantification of HSV-2 by qPCR, using the MIQE Guidelines. The reaction efficiency was evaluated, and the relative quantification used the R = 2-ΔCq method. The relative quantification of HSV-2 was conducted with anal and genital samples from men who have sex with men (MSM), living with HIV. The presence of a single amplification product was validated with a dissociation curves profile and the determination of the melting temperature. The limit of detection for β-globin was determined as 3.3 × 10-5 ng/μL, and for HSV-2 at 6.0 × 10-6 ng/μL. The efficiency for β-globin was 100.2% and for HSV-2 was 106.8%. From 336 MSM, 2.1% and 3.9% individuals presented anal or genital HSV-2 shedding, respectively. The HSV-2 viral load was 9.2 RU, individuals with fewer CD4+ presented higher HSV-2 viral load. The qPCR method is reproducible and has optimal reaction efficiency.

Abstract
BACKGROUND Quantitative estimation of the extent to which the immune system's protective effect against one herpes simplex virus type 2 (HSV-2) infection protects against infection with additional HSV-2 strains is important for understanding the potential for HSV-2 vaccine development. Using viral genotyping, we estimated the prevalence of HSV-2 dual-strain infection and identified risk factors. METHODS AND FINDINGS People with and without HIV infection participating in HSV-2 natural history studies (University of Washington Virology Research Clinic) and HIV prevention trials (HIV Prevention Trials Network 039 and Partners in Prevention HSV/HIV Transmission Study) in the US, Africa, and Peru with 2 genital specimens each containing ≥105 copies herpes simplex virus DNA/ml collected a median of 5 months apart (IQR: 2-11 months) were included. It is unlikely that 2 strains would be detected in the same sample simultaneously; therefore, 2 samples were required to detect dual-strain infection. We identified 85 HSV-2 SNPs that, in aggregate, could determine whether paired HSV-2 strains were the same or different with >90% probability. These SNPs were then used to create a customized high-throughput array-based genotyping assay. Participants were considered to be infected with more than 1 strain of HSV-2 if their samples differed by ≥5 SNPs between the paired samples, and dual-strain infection was confirmed using high-throughput sequencing (HTS). We genotyped pairs of genital specimens from 459 people; 213 (46%) were men, the median age was 34 years (IQR: 27-44), and 130 (28%) were HIV seropositive. Overall, 272 (59%) people were from the US, 59 (13%) were from Peru, and 128 (28%) were from 8 countries in Africa. Of the 459 people, 18 (3.9%) met the criteria for dual-strain infection. HTS and phylogenetic analysis of paired specimens confirmed shedding of 2 distinct HSV-2 strains collected at different times in 17 pairs, giving an estimated dual-strain infection prevalence of 3.7% (95% CI = 2.0%-5.4%). Paired samples with dual-strain infection differed by a median of 274 SNPs in the UL_US region (range 129-413). Matching our observed dual-strain infection frequency to simulated data of varying prevalences and allowing only 2 samples per person, we inferred the true prevalence of dual-strain infection to be 7%. In multivariable analysis, controlling for HIV status and continent of origin, people from Africa had a higher risk for dual-strain infection (risk ratio [RR] = 9.20, 95% CI = 2.05-41.32), as did people who were HIV seropositive (RR = 4.06, 95% CI = 1.42-11.56). CONCLUSIONS HSV-2 dual-strain infection was detected in 3.7% of paired samples from individual participants, and was more frequent among people with HIV infection. Simulations suggest that the true prevalence of dual-strain infection is 7%. Our data indicate that naturally occurring immunity to HSV-2 may be protective against infection with a second strain. This study is limited by the inability to determine the timing of acquisition of the second strain.

Abstract
BACKGROUND High risk human papillomavirus (hr-HPV) infection and the dual burden of HIV remains a huge challenge in some low-income countries (LICs) such as Swaziland with limited or no data. We estimated the prevalence and investigated determinants of hr-HPV, including HIV infection among sexually active women in Swaziland. METHODS A total of 655 women aged between 15 and 49 years from five health facilities were randomly enrolled using a cross-sectional study design. Cervical cells were tested for hr-HPV types using GeneXpert HPV Assays. RESULTS The overall weighted hr-HPV prevalence was 46.2% (95%CI: 42.8-49.5). Of hr-HPV infected women, 12.4% (95%CI: 8.6-17.5) were HPV16-positive, 13.8% (95%CI:12.0-15.8) were positive for HPV18/45, 26.7% (95%CI: 24.2-29.3) for HPV31/33/35/52/58, 7.6% (95%CI: 7.6-11.9) for HPV51/59 and 11.0%, (95%CI: 7.9-15.3) for HPV39/56/66/68. Prevalence of hr-HPV decreased with increasing age. Overall HIV prevalence remained high (42.7%; 95%CI: 35.7-46.2). HIV infection was associated with hr-HPV infection (Adjusted OR = 4.9, 95%CI: 3.043-7.8, p<0.001). Overall hr-HPV/HIV co-infection was 24.4% (95%CI: 20.3-29.1) which was significantly higher among younger age groups (p<0.001). Prevalence of multiple group hr-HPV infection was significantly higher in HIV-positive versus -negative women (27.7% and 12.7% respectively, p<0.001). The presence, absence or unknown of history of STI with HIV did not appear to modify the relationship with hr-HPV (OR = 4.2, 95%CI: 2.6-7.1, OR = 4.6, 95%CI: 2.8-7.7, p<0.001, p<0.001 and OR = 4.1, 95%CI: 1.3-13.4, p<0.021 respectively). CONCLUSION The prevalence of hr-HPV infection was high and significantly associated with HIV among sexually active women. Furthermore, the study has provided essential information about the HIV link with hr-HPV infections which may explain the high prevalence among HIV infected women. This can contribute to policy development and planning of prevention strategies incorporating HPV infection prevention especially among youth and HIV infected people.

Abstract
This study assessed the prevalence and determinants of herpes simplex virus type 2 (HSV-2)/syphilis co-infection and HSV-2 mono-infection in human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) in China. A cross-sectional study was conducted of 545 HIV-positive MSM in Shenyang between February 2009 and October 2014. Participants underwent physical examinations and serological tests for HSV-2 and syphilis. A multinomial logistic regression was used to identify the risk factors associated with HSV-2/syphilis co-infection and HSV-2 mono-infection. The prevalence of HSV-2 mono-infection, syphilis mono-infection, and HSV-2/syphilis co-infection (95% confidence interval) was 48.6% (44.4-52.8%), 34.3% (30.3-38.3%), and 22.9% (19.4-26.5%), respectively. After controlling within HSV-2/syphilis-seropositive cases, regression analysis revealed that the related factors for HSV-2/syphilis co-infection included age (25-50 vs. ≤ 24 years: adjusted odds ratio [aOR], 4.55; > 50 vs. ≤ 24 years: aOR, 43.02), having regular female sexual partner(s) in the past 6 months (aOR, 0.43), and age at first MSM experience (≤ 18 vs. > 18 years: aOR, 2.59) (all P < 0.05). The high prevalence of HSV-2 mono infection and HSV-2/syphilis co-infection in HIV-positive MSM indicates a high secondary HIV transmission risk. A campaign for detection and treatment of HSV-2 and syphilis is urgently required for HIV-positive MSM in China.

Abstract
BACKGROUND Little is known about viral co-infections in African human immunodeficiency virus (HIV)-infected children. We examined the prevalence of seromarkers for cytomegalovirus (CMV), herpes simplex virus type 2 (HSV-2) and hepatitis B virus (HBV) infections among HIV-infected, antiretroviral treatment (ART)-naïve children in Lilongwe, Malawi. METHODS Ninety-one serum samples were tested for IgG and IgM antibodies to CMV, and IgG antibodies to HSV-2 and hepatitis B surface antigen (HBsAg). Baseline demographic, clinical and laboratory data were abstracted from electronic records. RESULTS CMV IgG was the most common positive result in all age groups (in 73% of children <1 year, and 100% in all other groups). Three patients were CMV IgM positive (3.3%), suggesting acute infection. HSV-2 IgG was positive in four patients (4.4%), and HBsAg in two (2.2%). CONCLUSIONS CMV infection occurred early in life, and few children had specific signs of CMV infection at the time of ART initiation. Unrecognized HBV infection represents opportunities for testing and treatment of HIV/HBV co-infected children.

Abstract
Herpes simplex virus type 2 (HSV-2) is the cause of most genital herpes while HSV-1 is responsible for orolabial and facial lesions. In immunocompromised individuals, like HIV patients, impaired immunity leads to more frequent symptomatic and asymptomatic HSV infection. Fifty-two blood samples from HIV patients with clinically diagnosed HSV infection were taken as cases, while 45 blood samples each from HIV-infected (HIV control) and noninfected patients without any herpetic lesion (non-HIV control) were taken as control. Serum was tested for IgM and IgG antibodies of both HSV-1 and HSV-2 by ELISA. The seroprevalence was compared among the three groups of study population, considering the demographic and socioeconomic parameters. The HSV-2 IgM was significantly higher (p < 0.005) in the HIV patient group (34.6%) than the HIV control (2.2%) and non-HIV control (2.2%) groups, whereas HSV-2 IgG seroprevalence was higher in both HIV patient (61.5%) and HIV control (57.8%) groups than the non-HIV control group (17.8%). The prevalence of HSV-2 was significantly higher in persons with multiple partners and in the reproductive age group. The overall seroprevalence of HSV-1 IgM was too low (<5%), whereas it was too high (about 90%) with HSV-1 IgG in all three study groups.

Abstract
The human virome plays important roles in health and immunity. However, current methods for detecting viral infections and antiviral responses have limited throughput and coverage. Here, we present VirScan, a high-throughput method to comprehensively analyze antiviral antibodies using immunoprecipitation and massively parallel DNA sequencing of a bacteriophage library displaying proteome-wide peptides from all human viruses. We assayed over 10(8) antibody-peptide interactions in 569 humans across four continents, nearly doubling the number of previously established viral epitopes. We detected antibodies to an average of 10 viral species per person and 84 species in at least two individuals. Although rates of specific virus exposure were heterogeneous across populations, antibody responses targeted strongly conserved "public epitopes" for each virus, suggesting that they may elicit highly similar antibodies. VirScan is a powerful approach for studying interactions between the virome and the immune system.

Abstract
BACKGROUND The World Health Organization estimates that 536 million people aged 15-49 are infected with Herpes simplex virus type 2 (HSV-2), the causative agent of genital herpes. The aim of this study was to investigate the role of behavioral and demographic factors that contribute to the high HSV-2 sero-prevalence among women participating in a HIV prevention trial. The Methods for Improving Reproductive Health in Africa (MIRA) study assessed the effectiveness the latex diaphragm and lubricant gel on HIV prevention among women in South Africa and Zimbabwe. At screening an interviewer administered questionnaire on demographics and sexual behaviour was obtained. HSV-2 serum antibodies were detected using HerpeSelect™ ELISA IgG. Statistical analysis was performed using STATA release 12.0. This study was registered with ClinicalTrials.gov,number NCT00121459 on the 28th February 2007. FINDINGS Of the 3 472 women screened at the Durban research sites 2 218 (73%) had a prevalent HSV-2 infection and 1431 (41%) of the women were also co-infected with HIV. In the multivariate analyses, older women (adjusted odds ratio) [aOR]: 3.49, 95% CI: (2.71,4.49) for >35 years and aOR: 1.82, 95% CI: 1.49, 2.22 for 25-34 years compared with <25 years, p < 0.001 for both comparisons were more likely to be HSV-2 sero-positive. Low level of education (OR: 1.26 95% CI: 1.03, 1.53), having >1 life-time sexual partners (OR: 2.48, 95% CI: 1.92, 3.20), parity >1 (OR: 1.95 95% CI: 1.92, 3.20) and being HIV positive (OR: 6.31, 95% CI: 5.06, 7.88) were significantly associated with HSV-2 infection. CONCLUSION The high sero-prevalence of HSV-2 in the studied population is of great public health importance since this high risk population could act as a reservoir for future infections particularly HIV transmission.

Abstract
Introduction. In regional state of the study area, HIV (Human Immunodeficiency Virus) prevalence is 2.2% and opportunistic infections (OIs) occurred in 88.9% of pre-ART (Antiretroviral Therapy) people living with HIV/AIDS (PLWHA). Even though OIs are prevalent in the study area, duration of staying free from acquiring rehappening opportunistic infections and its determinant factors are not studied. Method. The study was conducted in randomly selected 341 adult Pre-ART PLWHA who are included in chronic HIV care. OI free duration was estimated using the actuarial life table and Kaplan Meier survival. Cox proportional-hazard model was used to calculate hazard rate. Result. OIs were rediagnosed in three quarters (75.37%) participants. In each week the probability of getting new recurrence OI was about 15.04 per 1000 person weeks. The median duration of not acquiring OI recurrence was 54 weeks. After adjustment, variables associated with recurrence were employment status, marital status, exposure for prophylaxis and adherence to it, CD4 count, and hemoglobin value. Conclusion. Giving prophylaxis and counseling to adhere it, rise in CD4 and hemoglobin level, and enhancing job opportunities should be given for PLWHA who are on chronic HIV care while continuing the care.

Abstract
Seroprevalence data of human herpesviruses (HHVs) are limited for sub-Saharan Africa. These are important to provide an indication of potential burden of HHV-related disease, in particular in human immunodeficiency virus (HIV)-infected individuals who are known to be at increased risk of these conditions in the Western world. In this cross-sectional study among 405 HIV-infected and antiretroviral therapy naïve individuals in rural South Africa the seroprevalence of HHVs was: herpes simplex virus type 1 (HSV-1) (98%), herpes simplex virus type 2 (HSV-2) (87%), varicella zoster virus (VZV) (89%), and 100% for both Epstein-Barr virus (EBV) and cytomegalovirus (CMV). Independent factors associated with VZV seropositivity were low educational status and having children. Lack of in-house access to drinking water was independently associated with positive HSV-1 serostatus, whereas Shangaan ethnicity was associated with HSV-2 seropositivity. Increasing age was associated with higher IgG titres to both EBV and CMV, whereas CD4 cell count was negatively associated with EBV and CMV IgG titres. Moreover, IgG titres of HSV-1 and 2, VZV and CMV, and CMV and EBV were positively correlated. The high HHV seroprevalence emphasises the importance of awareness of these viral infections in HIV-infected individuals in South Africa.

Hum Immunol 2014; 75:715-29.

Abstract
A significant portion of the world's population is infected with herpes simplex virus type 1 and/or type 2 (HSV-1 and/or HSV-2), that cause a wide range of diseases including genital herpes, oro-facial herpes, and the potentially blinding ocular herpes. While the global prevalence and distribution of HSV-1 and HSV-2 infections cannot be exactly established, the general trends indicate that: (i) HSV-1 infections are much more prevalent globally than HSV-2; (ii) over a half billion people worldwide are infected with HSV-2; (iii) the sub-Saharan African populations account for a disproportionate burden of genital herpes infections and diseases; (iv) the dramatic differences in the prevalence of herpes infections between regions of the world appear to be associated with differences in the frequencies of human leukocyte antigen (HLA) alleles. The present report: (i) analyzes the prevalence of HSV-1 and HSV-2 infections across various regions of the world; (ii) analyzes potential associations of common HLA-A, HLA-B and HLA-C alleles with the prevalence of HSV-1 and HSV-2 infections in the Caucasoid, Oriental, Hispanic and Black major populations; and (iii) discusses how our recently developed HLA-A, HLA-B, and HLA-C transgenic/H-2 class I null mice will help validate HLA/herpes prevalence associations. Overall, high prevalence of herpes infection and disease appears to be associated with high frequency of HLA-A(∗)24, HLA-B(∗)27, HLA-B(∗)53 and HLA-B(∗)58 alleles. In contrast, low prevalence of herpes infection and disease appears to be associated with high frequency of HLA-B(∗)44 allele. The finding will aid in developing a T-cell epitope-based universal herpes vaccine and immunotherapy.

Abstract
BACKGROUND This study aimed to identify the characteristics of HIV and herpes simplex virus (HSV)-2 seroprevalence in male patients with anal disease. METHODS HIV seroprevalence was estimated for different age groups of male patients with anal disease who were treated at Songdo colorectal hospital in Korea between 2001 and 2011. HIV seroprevalence of patients with anal disease was compared with that of patients with nonanal disease for each year from 2007 to 2011. HSV-2 antibody tests were conducted on 2,038 HIV-tested male patients with anal disease in 2009. RESULTS For 11 years from 2001, HIV seroprevalence differed significantly by age group (P < 0.001) and was highest in the group aged <20 years. From 2007 to 2011, HIV seroprevalence in patients with anal disease was 7.6/10,000-13.3/10,000 and that in patients with nonanal disease was 0-0.9/10,000. HSV-2 seroprevalence among patients with anal disease was 24.0%, and only one patient with HIV and HSV-2 was observed. CONCLUSIONS HIV seroprevalencein male patients with anal disease was significantly higher than that for other diseases. HSV-2 seroprevalence was similar to that in the general male population. Implementation of the current HIV surveillance system for male patients at colorectal hospitals is necessary to help prevent HIV transmission.

Abstract
Background Herpes simplex virus (HSV) infection is one of the commonest viral sexually transmitted infections (STIs). The aim of this study was to evaluate the prevalence of STIs among HSV positive patients at a tertiary hospital in Jeddah. Secondary objective of the study included the description of the demographic and clinical profile of patients with HSV and HIV co-infection. Methods A retrospective chart review of the medical records was performed for HSV positive women who presented to the emergency room and outpatient department of King Abdulaziz University Hospital, Jeddah, Saudi Arabia between January 1, 2003 and August 30, 2011. Data were collected from the medical records of all the patients and analyzed using the Statistical Package for the Social Sciences. Results Three hundred forty-three HSV positive patients were included in this study. Co-infection with HIV was documented in 45 patients (13.1%). Other STIs included chlamydia (n = 43, 12.5%), gonorrhea (n = 44, 12.8%), hepatitis B infection (n = 8, 2.3%), and cytomegalovirus infection (n = 37, 10.8%). Nineteen patients (5.5%) had a total of 47 term pregnancies and five abortions post HSV diagnosis. Genital ulcer disease was diagnosed in 11 (57.9%) of the cases during labor. One newborn developed neonatal herpes infection and subsequently showed delayed psychomotor development during follow up. Genital herpes was diagnosed in one patient’s partner; however, there was no documentation of screening for STIs in the partners of the other patients. Conclusions Sexually transmitted infections are relatively common among HSV positive patients at King Abdulaziz University Hospital. Amongst these, HIV is the most common, with a prevalence of 13.1%. Further studies are warranted to evaluate STIs in Saudi Arabia. Health policy makers should adopt a protocol to screen for STIs in the partners of persons who are positive for any STI as early detection and appropriate treatment can improve the outcome.

Abstract
Combination antiretroviral therapy (cART) has resulted in tremendous gains in survival among HIV-infected patients, but as a group those who achieve undetectable viral loads on cART experience a greater degree of immune activation and inflammation than the general population. HIV-infected patients continue to experience premature immune senescence with earlier and more frequent non-AIDS events compared to HIV-uninfected individuals. Chronic immune activation during suppressive cART derives from a variety of sources mediated by cytokines, chemokines, coagulation, microbial translocation, immune regulators and T(effector) cell activation abnormalities, among others. Current investigational strategies to control immune activation target potential causes of persistently heightened immune activation during cART such as microbial translocation, co-infections, and comorbidities or mediators along a common final pathway. Although several interventions have shown promise in vitro or in preliminary clinical trials, no intervention has sufficient evidence for routine use, making control of immune activation during cART an unmet need.

Exploiting the anti-HIV-1 activity of acyclovir: suppression of primary and drug-resistant HIV isolates and potentiation of the activity by ribavirin. Antimicrob Agents Chemother 2012; 56:2604-11.

Abstract
Multiple clinical trials have demonstrated that herpes simplex virus 2 (HSV-2) suppressive therapy using acyclovir (ACV) or valacyclovir in HIV-1/HSV-2-infected persons increased the patient's survival and decreased the HIV-1 load. It has been shown that the incorporation of ACV-monophosphate into the nascent DNA chain instead of dGMP results in the termination of viral DNA elongation and directly inhibits laboratory strains of HIV-1. We evaluated here the anti-HIV activity of ACV against primary HIV-1 isolates of different clades and coreceptor specificity and against viral isolates resistant to currently used drugs, including zidovudine, lamivudine, nevirapine, a combination of nucleoside reverse transcriptase inhibitors (NRTIs), a fusion inhibitor, and two protease inhibitors. We found that, at clinically relevant concentrations, ACV inhibits the replication of these isolates in human tissues infected ex vivo. Moreover, addition of ribavirin, an antiviral capable of depleting the pool of intracellular dGTP, potentiated the ACV-mediated HIV-1 suppression. These data warrant further clinical investigations of the benefits of using inexpensive and safe ACV alone or in combination with other drugs against HIV-1, especially to complement or delay highly active antiretroviral therapy (HAART) initiation in low-resource settings.
