Clin Cosmet Investig Dermatol 2024; 17:1887-1893. [PMID: 39193095 PMCID: PMC11348932 DOI: 10.2147/ccid.s470020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Accepted: 07/31/2024] [Indexed: 08/29/2024]
Abstract
Objective To assess the accuracy of HSV1and HSV2 antibody testing in identifying genital herpes infection. Methods A cohort of 299 patients previously diagnosed with recurrent genital herpes, confirmed via PCR, were tested using ELISA for HSV1 and HSV2 IgM and IgG antibodies. The study compared the accuracy of HSV1 and HSV2 antibody tests in diagnosing genital herpes. Results Among 299 patients, 14 tested positives for HSV1 DNA. Of these, 9 had HSV1 IgG antibodies, but none had HSV2 IgG antibody. Among 278 patients with HSV2 DNA, 149 had HSV1 IgG, 9 had HSV2 IgG, and 97 had both. Seven patients had both HSV1 and HSV2 DNA; 3 had HSV1 IgG, 1 had HSV2 IgG, and 3 had both. The accuracy of HSV1 IgG for HSV1 infection was 64.2%, and for HSV1 and HSV2 co-infection, 85.7%. The accuracy of HSV2 IgG for HSV2 infection was 38.1%, and for HSV1 and HSV2 co-infection, 57.1%. The combined antibody positivity accuracy was 34.9%. Conclusion Genital herpes is primarily caused by HSV2 (92.98%). A smaller percentage is HSV1 (4.67%) or co-infection (2.34%). Despite relatively low diagnostic accuracy (34.9-85.7%) for antibody detection, combined antibody testing is necessary. Herpes DNA testing is recommended for accurate diagnosis. Absence of antibodies does not rule out genital herpes and clinical assessment is essential.

Seroprevalence of Chlamydia trachomatis, herpes simplex 2, Epstein-Barr virus, hepatitis C and associated factors among a cohort of men ages 18-70 years from three countries. PLoS One 2021; 16:e0253005. [PMID: 34157055 PMCID: PMC8219163 DOI: 10.1371/journal.pone.0253005] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Accepted: 05/26/2021] [Indexed: 12/19/2022] Open
Abstract
Objectives To estimate the seroprevalence of Chlamydia trachomatis (CT), herpes simplex type-2 (HSV2), hepatitis C (HCV), Epstein-Barr virus (EBV) and nine human papilloma virus (HPV) types, and investigated factors associated with the seropositivity among men from three countries (Brazil, Mexico and U.S). Methods Archived serum specimens collected at enrollment for n = 600 men were tested for antibodies against CT, HSV2, HCV, EBV, and 9-valent HPV vaccine types (6/11/16/18/31/33/45/52/58) using multiplex serologic assays. Socio-demographic, lifestyle and sexual behavior data at enrollment were collected through a questionnaire. Results Overall, 39.3% of the men were seropositive for CT, 25.4% for HSV2, 1.3% for HCV, 97.3% for EBV, 14.0% for at least one of the seven oncogenic HPV (types: 16/18/31/33/45/52/58), and 17.4% for HPV 6/11. In the unadjusted models, age, race, smoking, sexual behavior variables, and seropositivity for high-risk HPV were significantly associated with the seropositivity for CT. In multivariable analyses, self-reported black race, higher numbers of lifetime female/male sexual partners, current smoking, and seropositivity to high-risk HPV were significantly associated with increased odds of CT seropositivity. Odds of HSV2 seroprevalence were elevated among older men and those seropositive for high risk HPV. Conclusion Exposure to STIs is common among men. Prevention and screening programs should target high-risk groups to reduce the disease burden among men, and to interrupt the disease transmission to sexual partners.

JMIR Public Health Surveill 2019; 5:e14216. [PMID: 31124465 PMCID: PMC6552407 DOI: 10.2196/14216] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2019] [Revised: 04/26/2019] [Accepted: 04/26/2019] [Indexed: 12/31/2022] Open
Abstract
Background Herpes simplex virus (HSV)-1 and HSV-2 are common infections affecting the global population, with HSV-1 estimated to affect 67% of the global population. HSV can have rare but severe manifestations, such as encephalitis and neonatal herpes, necessitating the use of reliable and accurate diagnostic tools for the detection of the viruses. Currently used HSV diagnostic tools require highly specialized skills and availability of a laboratory setting but may lack sensitivity. The numerous recently developed HSV diagnostic tools need to be identified and compared in a systematic way to make the best decision about which diagnostic tool to use. The diagnosis of HSV is essential for prompt treatment with antivirals. To select the best test for a patient, knowledge of the performance and limitations of each test is critical. Objective This systematic review has summarized recent studies evaluating HSV-1 and HSV-2 diagnostic tools. Methods Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, selection criteria, data extraction, and data analysis were determined before the commencement of the study. Studies assessing the specificity/sensitivity of HSV-1 or HSV-2 diagnostic tools published between 2012 and 2018 were included. Quality assessment of included studies was performed using the quality assessment of diagnostic accuracy studies (QUADAS-2) tool. Results Searches of the PubMed database yielded 264 studies; 11 studies included 11 molecular assays, and 8 studies included 19 different serological assays for the detection of HSV-1, HSV-2, or both. A greater proportion of molecular assay–based tools are being developed by commercial entities. Studies that tested molecular assays mostly focused on cutaneous and mucosal HSV infections (n=13); 2 studies focused on ocular disease, whereas only 1 study focused on the central nervous system manifestations. The Simplexa HSV 1 & 2 Direct is currently the only Food and Drug Administration–approved device for use on cerebrospinal fluid. No tools focused on prenatal screening. We also present performance metrics of tests for benchmarking of future technology. Most of the included studies had a high risk of bias rating in half of the QUADAS-2 tool risk of bias domains. Conclusions The use of serologic tests to diagnose genital lesions is inappropriate because positive results may be due to chronic infection, whereas negative results may overlook recent infection. The incidence of acute infections is rising. As these infections present the greatest risk to fetuses, work needs to be done to prevent vertical transfer. Prenatal screening for primary infection and subsequent medical intervention will assist in lowering the rate of neonatal herpes. In conclusion, HSV diagnosis is moving away from culture-based methods to serology-based or polymerase chain reaction–based methods. Sensitive, rapid, and efficient HSV diagnostic tools should be adopted for the prevention of acute infections and neonatal herpes.

Abstract
OBJECTIVES Herpes simplex virus (HSV) type-discriminating antibody tests (glycoprotein G (gG) directed) are used to identify naïve persons and differentiate acute infections from recurrences. We studied test characteristics of three commercially available antibody tests in patients with recurrent (established by viral PCR tests) herpes simplex virus type 1 (HSV-1) or herpes simplex virus type 2 (HSV-2) genital herpes episodes. METHODS Serum samples (at minimum 3 months after t=0) were examined for the presence of gG-1-specific or gG-2-specific antibodies using the HerpeSelect 1 and 2 Immunoblot IgG, the HerpeSelect 1 and 2 enzyme linked immunoassays IgG and the LIAISON HSV-1 and HSV-2 IgG indirect chemiluminescence immunoassays. RESULTS The immunoblot was HSV-1 positive in 70.6% (95% CI 44.0% to 89.7%), the LIAISON in 88.2% (95% CI 63.5% to 98.5%) and the ELISA in 82.4% (95% CI 56.6% to 96.2%) of the 17 patients with a recurrent HSV-1 episode. From 33 patients with a recurrent HSV-2 episode, the immunoblot was HSV-2 positive in 84.8% (95% CI 68.1% to 94.9%), the LIAISON in 69.7% (95% CI 51.3% to 84.4%) and the ELISA in 84.8% (95% CI 68.1% to 94.9%). Among 15/17 (88.2%; 95% CI 63.5% to 98.5%) patients with HSV-1 and 30/33 (90.1%; 95% CI 75.7% to 98.1%) patients with HSV-2, HSV-1 or HSV-2 antibodies, respectively, were detected in at least one of the three antibody tests. CONCLUSIONS Commercial type-specific gG HSV-1 or HSV-2 antibody assays were false negative in 12-30% of patients with recurrent HSV-1 or HSV-2 DNA positive genital lesions. The clinical and epidemiological use of type-specific HSV serology can be hampered by false-negative results, especially if based on a single test.

Global Diversity within and between Human Herpesvirus 1 and 2 Glycoproteins. J Virol 2015; 89:8206-18. [PMID: 26018161 DOI: 10.1128/jvi.01302-15] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2015] [Accepted: 05/19/2015] [Indexed: 12/17/2022] Open
Abstract
UNLABELLED Human herpes simplex viruses 1 and 2 (HSV-1 and HSV-2) are large-genome DNA viruses that establish a persistent infection in sensory neurons and commonly manifest with recurring oral or genital erosions that transmit virus. HSV encodes 12 predicted glycoproteins that serve various functions, including cellular attachment, entry, and egress. Glycoprotein G is currently the target of an antibody test to differentiate HSV-1 from HSV-2; however, this test has shown reduced capacity to differentiate HSV strains in East Africa. Until the recent availability of 26 full-length HSV-1 and 36 full-length HSV-2 sequences, minimal comparative information was available for these viruses. In this study, we use a variety of sequence analysis methods to compare all available sequence data for HSV-1 and HSV-2 glycoproteins, using viruses isolated in Europe, Asia, North America, the Republic of South Africa, and East Africa. We found numerous differences in diversity, nonsynonymous/synonymous substitution rates, and recombination rates between HSV-1 glycoproteins and their HSV-2 counterparts. Phylogenetic analysis revealed that while most global HSV-2 glycoprotein G sequences did not form clusters within or between continents, one clade (supported at 60.5%) contained 37% of the African sequences analyzed. Accordingly, sequences from this African subset contained unique amino acid signatures, not only in glycoprotein G, but also in glycoproteins I and E, which may account for the failure of sensitive antibody tests to distinguish HSV-1 from HSV-2 in some African individuals. Consensus sequences generated in the study can be used to improve diagnostic assays that differentiate HSV-1 from HSV-2 in global populations. IMPORTANCE Human herpes simplex viruses 1 and 2 (HSV-1 and HSV-2) are large DNA viruses associated with recurring oral or genital erosions that transmit virus. Up to 12 HSV-1 and HSV-2 glycoproteins are involved in HSV cell entry or are required for viral spread in animals, albeit some are dispensable for replication in vitro. The recent availability of comparable numbers of full-length HSV-1 and HSV-2 sequences enabled comparative analysis of gene diversity of glycoproteins within and between HSV types. Overall, we found less glycoprotein sequence diversity within HSV-2 than within the HSV-1 strains studied, while at the same time, several HSV-2 glycoproteins were evolving under less selective pressure. Because HSV glycoproteins are the focus of antibody tests to detect and differentiate between infections with the two strains and are constituents of vaccines in clinical-stage development, these findings will aid in refining the targets for diagnostic tests and vaccines.

Abstract
Epidemiologic links between chronic hepatitis C and herpes simplex type-2 infection have been suggested; however, type-specific tests for HSV-2 infection have not been validated in patients with chronic hepatitis C infection. The Focus HerpeSelect(®) HSV-2 IgG (Cypress, California) assay and the Biokit HSV-2 rapid assay (Biokit USA, Lexington, MA) were performed on serum samples obtained from 84 veterans with chronic hepatitis C who demonstrated a previously positive HSV-2 serologic test in their medical records. Using the Biokit HSV-2 as the comparator assay, the positive predictive value, and specificity for the HerpeSelect(®) HSV-2 assay were 62.1% (95%CI: 49.3-73.8) and 41.9% (95%CI: 27.0-57.9), respectively. Increasing the HerpeSelect(®) HSV-2 index value defining a positive test result from >1.1 to ≥2.89 increased the assay's specificity to 97.7% (95%CI: 87.7-99.6) and the positive predictive value to 94.1%(95%CI: 71.2-99.0). J. Med. Virol. 9999: 1-5, 2015. © 2015 Wiley Periodicals, Inc. In veterans with chronic hepatitis C infection, HerpeSelect(®) HSV-2 index values between 1.1 and 2.89 should be confirmed with an alternate test for HSV-2 infection.

Abstract
OBJECTIVES Herpes simplex virus type 2 (HSV-2) is a common sexually transmitted disease, but there is limited data on its epidemiology among urban populations. The urban Emergency Department (ED) is a potential venue for surveillance as it predominantly serves an inner city minority population. We evaluate the seroprevalence and factors associated with HSV-2 infection among patients attending the Johns Hopkins Hospital Adult Emergency Department (JHH ED). METHODS An identity unlinked-serosurvey was conducted between 6/2007 and 9/2007 in the JHH ED; sera were tested by the Focus HerpeSelect ELISA. Prevalence risk ratios (PRR) were used to determine factors associated with HSV-2 infection. RESULTS Of 3,408 serum samples, 1,853 (54.4%) were seropositive for HSV-2. Females (adjPRR = 1.47, 95% CI 1.38-1.56), non-Hispanic blacks (adjPRR = 2.03, 95% CI 1.82-2.27), single (adjPRR = 1.15, 95% CI 1.07-1.25), divorced (adjPRR = 1.28, 95% CI 1.15-1.41), and unemployed patients (adjPRR = 1.13, 95% CI 1.05-1.21) had significantly higher rates of HSV-2 infection. Though certain zip codes had significantly higher seroprevalence of HSV-2, this effect was completely attenuated when controlling for age and gender. CONCLUSIONS Seroprevalence of HSV-2 in the JHH ED was higher than U.S. national estimates; however, factors associated with HSV-2 infection were similar. The high seroprevalence of HSV-2 in this urban ED highlights the need for targeted testing and treatment. Cross-sectional serosurveys in the urban ED may help to examine the epidemiology of HSV-2.

Abstract
Herpes simplex virus 1 (HSV-1) and 2 (HSV-2) cause a variety of human diseases, ranging from acute to chronic and mild to severe. The absence of curative therapy results in lifelong carriage marked by recurrent outbreaks and allows transmission of the virus to uninfected individuals. Nonspecific lesions, variable presentation, and chronic carriage necessitate the use of different laboratory testing methods appropriate for each presentation. A thorough understanding of the performance characteristics and limitations of available tests is critical for selection of the appropriate test and interpretation of results. Clinical sensitivity, specificity, and selection of the appropriate methodology is paramount to avoid misdiagnosis and guide therapy. In this article we review the different methods for detection and typing of HSV, including light microscopy, culture, serology, and nucleic acid-based tests. We discuss the strengths and weaknesses of each method for diagnosing HSV infection, cite performance characteristics, and review appropriate clinical uses.

Abstract
The BED capture enzyme immunoassay (BED-CEIA) was developed for estimating HIV incidence from cross-sectional data. This assay misclassifies some individuals with nonrecent HIV infection as recently infected, leading to overestimation of HIV incidence. We analyzed factors associated with misclassification by the BED-CEIA. We analyzed samples from 383 men who were diagnosed with HIV infection less than 1 year after a negative HIV test (Multicenter AIDS Cohort Study). Samples were collected 2-8 years after HIV seroconversion, which was defined as the midpoint between the last negative and first positive HIV test. Samples were analyzed using the BED-CEIA with a cutoff of OD-n ≤ 0.8 for recent infection. Logistic regression was used to identify factors associated with misclassification. Ninety-one (15.1%) of 603 samples were misclassified. In multivariate models, misclassification was independently associated with highly active antiretroviral treatment (HAART) for >2 years, HIV RNA <400 copies/ml, and CD4 cell count <50 or <200 cells/mm(3); adjusted odds ratios (OR) and 95% confidence intervals (CI) were 4.72 (1.35-16.5), 3.96 (1.53-10.3), 6.85 (2.71-17.4), and 11.5 (3.64-36.0), respectively. Among 220 men with paired samples, misclassification 2-4 years after seroconversion was significantly associated with misclassification 6-8 years after seroconversion [adjusted OR: 25.8 (95% CI: 8.17-81.5), p<0.001] after adjusting for race, CD4 cell count, HIV viral load, and HAART use. Low HIV viral load, low CD4 cell count, and >2 years of HAART were significantly associated with misclassification using the BED-CEIA. Some men were persistently misclassified as recently infected up to 8 years after HIV seroconversion.

Abstract
Background & objectives: Sexually transmitted infections (STIs) enhance the transmission of human immunodeficiency virus (HIV). Thus, screening for STIs is a routine component of primary HIV care. There are limited data for selective screening guidelines for genital mycoplasmas and Chlamydia trachomatis in HIV-infected adults. The aim of the present study was to determine the frequency of genital infections with Ureaplasma spp., Mycoplasma hominis, M. genitalium and C. trachomatis in treatment naïve asymptomatic HIV-1 - infected adults and study their association with CD4+ T-cell count. Methods: First-void urine samples were collected from 100 treatment-naïve HIV-1-infected adults and 50 healthy volunteers. C. trachomatis and M. genitalium were detected by polymerase chain reaction (PCR). Ureaplasma spp. and M. hominis were detected by both culture and PCR. Circulating CD4+ cell counts of HIV-1-infected patients were determined from peripheral blood by flow-cytometry. Results: C. trachomatis was detected in 7 per cent of HIV-1-infected adults compared to none in control population. Ureaplasma spp. and M. hominis showed infection rates of 6 and 1 per cent in the HIV group and 2 and 0 per cent in the control group, respectively. None of the individuals from the patient and control groups was tested positive for M. genitalium. A significant association was found between CD4 cell count and detection of C. trachomatis in HIV-infected adults (P = 0.01). Interpretation & conclusions: Screening of HIV-infected individuals for C. trachomatis infection could be recommended as a routine component of HIV care. The role of mycoplasmas as co-pathogens of the genitourinary tract in HIV-1 infected patients seems to be unlikely. Further longitudinal studies need to be done to confirm these findings.

Abstract
Herpes simplex virus type 2 (HSV-2) infection is one of the most common sexually transmitted infections (STIs) worldwide. While glycoprotein G-2 enzyme-linked immunosorbent assays are commonly used for the serological detection of HSV-2 antibodies, they have low specificity in developing countries. The Euroline Western blot (WB) is a commercially available assay that is easy to perform; however, little is known about its performance characteristics. This study evaluated Euroline WB for the detection of HSV-2 antibodies compared with University of Washington Western blot in three geographically different regions: Baltimore, MD, USA; Rakai, Uganda; and Kunming, China. Among the 135 American men attending a STI clinic in Baltimore, MD, 72% (n = 97) were HSV-2-positive by Euroline WB, showing a sensitivity of 97.8% and a specificity of 81.8%. Among the 273 commercial sex workers in Kunming, 62.3% were HSV-2-positive by Euroline WB (sensitivity 96.9%, specificity 89.1%). Among the 437 Ugandans in Rakai, 67.3% were HSV-2-positive by Euroline WB (sensitivity 98.7%, specificity 65.4%). The Euroline WB has a consistently high sensitivity, but specificity varied significantly among the different locations.

Abstract
BACKGROUND Herpes simplex virus (HSV)-type specific serology (TSS) testing has been commercially available for nearly a decade. Guidelines on appropriate use of such testing exist, including Canadian-based recommendations. Despite this, most Canadian laboratories do not offer HSV-type specific serology and many provide only nontype-specific HSV serology tests. METHODS At the Alberta Provincial Laboratory, HSV TSS is performed using the following algorithm (termed the Alberta algorithm). Eligible specimens are first tested with a nontype-specific kit (Behring Enzygnost IgG). If positive, sera are then tested using the Focus HerpeSelect-2 assay to establish HSV-2 infection. If the HerpeSelect-2 result is negative, the result is reported as anti-HSV-1 positive. In this study we sought a validation of the Alberta algorithm by testing 344 serum samples with the Behring Enzygnost IgG assay, the type specific Focus HerpeSelect 1 and 2 assays, and by Western blot (WB). RESULTS Taking the WB as a gold standard, the Behring Enzygnost IgG assay showed a sensitivity of 94% and a specificity of 100%, whereas the Alberta algorithm had a sensitivity of 92% and a specificity of 97% for the detection of HSV-2 antibodies, and a sensitivity of 94% and a specificity of 100% for the detection of HSV-1 antibodies in HSV-2 negative sera. Focus HerpeSelect 1 and HerpeSelect 2 sensitivities against WB were 88% and 91%, whereas specificities were 95% and 97% for HSV-1 and HSV-2, respectively. CONCLUSIONS The Alberta algorithm was at least equivalent to HerpeSelect 1 and 2 in detecting anti-HSV antibodies. Although sensitivity and specificity were higher, the differences were not statistically significant.

Abstract
OBJECTIVE To systematically review studies of Mycoplasma genitalium and the association with HIV infection in adults and to summarize the findings in a meta-analysis. DESIGN A systematic review and meta-analysis. METHODS Epidemiological studies of the association of M. genitalium and HIV infection published prior to June 2008 were identified in a systematic review of the published literature. A random-effects meta-analysis was used to calculate the summary odds ratio (OR) and 95% confidence interval (CI). Further analyses stratified by geographical area and type of control population, and sensitivity analyses were conducted to assess between-study heterogeneity and publication bias. RESULTS Nineteen eligible studies were identified. The prevalence of M. genitalium ranged from 3.1% to 47.5%. Seventeen studies found that participants with M. genitalium were more likely to be HIV infected, and this association was statistically significant in 12 studies. The summary odds ratio (OR) was 2.01 [95% confidence interval (CI) = 1.44-2.79]. The association was stronger in sub-group analyses among studies in sub-Saharan Africa (OR = 2.60, 95% CI = 2.17-3.11) and studies with healthy control populations (OR = 2.57, 95% CI = 2.05-3.22). There was strong evidence of between-study heterogeneity among all studies combined; however, between-study heterogeneity was substantially reduced in sub-group analyses. There was no statistical evidence of publication bias. CONCLUSION The strong association between M. genitalium and HIV infections in these primarily cross-sectional observational studies highlights the need for longitudinal studies to understand the temporal association between these infections. Testing and treatment of M. genitalium-positive individuals in high-risk populations should be investigated as a potential HIV prevention strategy.
