Psychosocial well-being and quality of life among women newly diagnosed with genital herpes

Epidemiology of herpes simplex virus type 1 in Canada: systematic review, meta-analyses, and meta-regressions

Background

The objective of this study was to characterize herpes simplex virus type 1 (HSV-1) epidemiology in Canada.

Methods

HSV-1 publications as recent as December 6, 2021 were systematically reviewed, synthesized, and reported following PRISMA guidelines. Meta-analyses and meta-regressions were conducted.

Results

HSV-1 measures were extracted from 22 studies and included 32 overall seroprevalence measures (79 stratified), 2 overall proportions of HSV-1 detection in clinically diagnosed genital ulcer disease (2 stratified), and 8 overall proportions of HSV-1 detection in laboratory-confirmed genital herpes (27 stratified). Pooled mean seroprevalence was 19.1% [95% confidence interval (CI): 12.6-26.4%] among healthy children and 51.4% (95% CI: 47.3-55.5%) among healthy adults. Pooled mean seroprevalence among healthy general populations increased with age, with the lowest being 35.7% (95% CI: 29.1-42.6%) among individuals <20 years of age, and the highest being 70.0% (95% CI: 54.8-83.2) among individuals ≥40 years. Seroprevalence increased by 1.02-fold (95% CI: 1.01-1.04) per year. Pooled mean proportion of HSV-1 detection in genital ulcer disease was 30.8% (95% CI: 12.6-52.8%). Pooled mean proportion of HSV-1 detection in genital herpes was 37.4% (95% CI: 29.5-45.6%) and was highest in women and in young persons. Proportion of HSV-1 detection in genital herpes increased by 1.04-fold (95% CI: 1.00-1.08) per year.

Conclusions

HSV-1 epidemiology in Canada appears to be shifting toward less oral acquisition in childhood and more genital acquisition in adulthood, particularly among youth. Both HSV-1 seroprevalence and proportion of HSV-1 detection in genital herpes are increasing with time.

Epidemiology of herpes simplex virus type 2 in the Middle East and North Africa: Systematic review, meta-analyses, and meta-regressions

BACKGROUND

Herpes simplex virus type 2 (HSV-2) infection is a prevalent, sexually transmitted infection with poorly characterized prevalence in the Middle East and North Africa (MENA) region. This study characterized HSV-2 epidemiology in MENA.

METHODS

The systematic review was guided by the Cochrane Collaboration Handbook and findings were reported following PRISMA guidelines. Random-effects meta-analyses and meta-regressions were performed to estimate pooled mean outcome measures and to assess predictors of HSV-2 antibody prevalence (seroprevalence), trends in seroprevalence, and between-study heterogeneity.

FINDINGS

61 overall (133 stratified) HSV-2 seroprevalence measures and two overall (4 stratified) proportion measures of HSV-2 detection in laboratory-confirmed genital herpes were extracted from 37 relevant publications. Pooled mean seroprevalence was 5.1% (95% CI: 3.6-6.8%) among general populations, 13.3% (95% CI: 8.6-18.7%) among intermediate-risk populations, 20.6% (95% CI: 5.3-42.3%) among female sex workers, and 18.3% (95% CI: 3.9-39.4%) among male sex workers. Compared to Fertile Crescent countries, seroprevalence was 3.39-fold (95% CI: 1.86-6.20) and 3.90-fold (95% CI: 1.78-8.57) higher in Maghreb and Horn of Africa countries, respectively. Compared to studies published before 2010, seroprevalence was 1.73-fold (95% CI: 1.00-2.99) higher in studies published after 2015. Pooled mean proportion of HSV-2 detection in genital herpes was 73.8% (95% CI: 42.2-95.9%).

CONCLUSION

MENA has a lower HSV-2 seroprevalence than other world regions. Yet, 1 in 20 adults is chronically infected, despite conservative prevailing sexual norms. Seroprevalence may also be increasing, unlike other world regions. Findings support the need for expansion of surveillance and monitoring of HSV-2 infection in MENA.

Epidemiology of herpes simplex virus type 1 and genital herpes in Australia and New Zealand: systematic review, meta-analyses and meta-regressions

Herpes simplex virus type 1 (HSV-1) infection is a lifelong infection that is acquired primarily orally and during childhood. We aimed to characterise HSV-1 epidemiology in Australia and New Zealand. HSV-1-related data as recent as 6 December 2021 were systematically reviewed, synthesised and reported, following PRISMA guidelines. Pooled mean seroprevalence and proportions of HSV-1 detection in genital ulcer disease (GUD) and in genital herpes were calculated using random-effects meta-analyses. Meta-regressions were also conducted. HSV-1 measures were retrieved from 21 eligible publications. Extracted HSV-1 measures included 13 overall seroprevalence measures (27 stratified) in Australia, four overall proportions of HSV-1 detection in clinically diagnosed GUD (four stratified) in Australia, and ten overall proportions of HSV-1 detection in laboratory-confirmed genital herpes (26 stratified) in Australia and New Zealand. Pooled mean seroprevalence among healthy adults in Australia was 84.8% (95% confidence interval (CI) 74.3-93.1%). Pooled mean seroprevalence was 70.2% (95% CI 47.4-88.7%) among individuals <35 years of age and 86.9% (95% CI 79.3-93.0%) among individuals ≥35 years. Seroprevalence increased by 1.05-fold (95% CI 1.01-1.10) per year. Pooled mean proportion of HSV-1 detection in GUD was 8.2% (95% CI 0.4-22.9%). Pooled mean proportion of HSV-1 detection in genital herpes was 30.5% (95% CI 23.3-38.3%), and was highest in young individuals. Proportion of HSV-1 detection in genital herpes increased by 1.04-fold (95% CI 1.00-1.08) per year. Included studies showed heterogeneity, but 30% of the heterogeneity in seroprevalence and 42% of the heterogeneity in proportion of HSV-1 detection in genital herpes were explained in terms of epidemiological factors. HSV-1 seroprevalence is higher in Australia than in other Western countries. HSV-1 epidemiology in Australia and New Zealand appears to be transitioning towards less oral acquisition in childhood, but more genital acquisition among youth.

Impact of primary and recurrent genital herpes on the quality of life of young people and adults: a mixed methods systematic review

OBJECTIVE

This review sought to identify the experiences of persons living with genital herpes and what interventions improve the health-related quality of life of young people and adults with primary or recurrent genital herpes.

INTRODUCTION

Genital herpes is commonly associated with psychosocial challenges. However, a growing body of evidence suggests that its impact can be ameliorated through pharmacological and psychosocial interventions.

INCLUSION CRITERIA

This review considered English- and German-language studies of community-dwelling males and females, of any ethnicity and geographical location, aged 15 years and older, who had primary or recurrent genital herpes. The quantitative component of the review included studies that reported on the virus' impact on patients' health-related quality of life and/or the efficacy of interventions in improving their health-related quality of life. Studies compared antiviral suppression therapies and psychological interventions with usual care or placebo, or against one another. The qualitative component of the review included studies that investigated the perceptions and experiences of young people and adults with genital herpes.

METHODS

Eleven databases were searched from January 1980 to March 2020. The JBI approach to mixed methods systematic reviews was followed at each stage of the review, and a convergent segregated approach to synthesis and integration was adopted.

RESULTS

A total of 31 publications covering 30 studies were deemed suitable for inclusion. Studies encompassed quantitative (n = 27, across 28 publications), qualitative (n = 1), and mixed methods (n = 2) designs. Critical appraisal scores were variable, particularly among the randomized controlled trials and the analytical cross-sectional studies. All studies were included regardless of methodological quality. The quantitative components identified that depression, illness concern, stress, anxiety, isolation, stigma, and a lowering of self-esteem, self-concept, self-confidence, and health-related quality of life may be experienced by both those newly diagnosed with genital herpes and those with recurrences. It was also identified that genital herpes can have an adverse effect on work or school, sexual relationships, and relationships with friends and family. Depression was found to significantly decrease after self-hypnosis and certain psychosocial interventions. Anxiety significantly decreased following pharmacological treatment, psychosocial interventions, and hypnosis. Psychosocial interventions significantly improved mood, and a self-help module with counseling significantly improved participants' satisfaction with intimate relationships and their self-esteem. Pharmacological treatment significantly improved health-related quality of life; however, there were no significant differences between different active treatment regimens. The qualitative component of the review led to the identification of two synthesized findings: "Disclosure of a diagnosis of genital herpes poses a dilemma for people who have the virus" and "A diagnosis of genital herpes has a significant emotional impact for the individual."Integration of quantitative and qualitative evidence revealed a consensus that a diagnosis of genital herpes has a significant emotional impact for individuals and that disclosure is stressful, affects relationships, and affects health-related quality of life; however, there is a lack of consensus regarding efficacy of different interventions.

CONCLUSIONS

Genital herpes can lead to extreme emotional, social, relational, and sexual distress, but there is insufficient knowledge concerning which interventions best improve health-related quality of life. More high-quality research is required.

Psychological health and well-being in patients with sexually transmitted infections: A prospective cross-sectional study

Background

Patients with sexually transmitted infections (STIs) suffer not only with the physical problems but also with various psychological problems. Majority of bacterial STIs are treatable in a short period, while viral STIs may persist for longer duration or have frequent recurrences.

Aims and Objectives

The aim of the study was To study different aspects of psychological health and well-being in patients with STIs.

Materials and Methods

Study design was a prospective cross-sectional hospital-based study. Data were collected during July 2016-April 2018. STIs were divided into four groups (genital herpes, genital warts, and genital discharge and syphilis). One way analysis of variance and Scheffe Test were used for analysis of the data.

Results

A total of 410 patients were included in the study. Majority of patients were suffering with genital herpes (139), followed by warts (104), discharge (92), and syphilis (75). Genital herpes and genital warts indicated significantly more cognitive affective (CA) depression as compared to the patients suffering with syphilis. Satisfaction with life was more with genital discharge and syphilis in comparison to the patients with genital warts and genital herpes. Genital herpes showed more perceived stress in comparison to genital discharge. Genital warts indicated more somatic depression as compared to syphilis and genital discharge patients while genital herpes showed more somatic depression than in patients suffering with genital discharge. Genital warts and genital herpes indicated significantly more overall depression as compared to the patients suffering with syphilis.

Conclusion

Overall depression was more in patients with genital herpes and warts. The findings provide empirical bases for extended studies on behavioral intervention programs.

Herpes simplex virus type 1 in Europe: systematic review, meta-analyses and meta-regressions

Objective

To describe the epidemiology of herpes simplex virus type 1 (HSV-1) in Europe.

Methods

We systematically reviewed HSV-1 related publications, conducted various meta-analyses and meta-regressions, assessed pooled mean seroprevalence, and estimated pooled mean proportions of HSV-1 viral detection in clinically diagnosed genital ulcer disease (GUD) and in genital herpes.

Results

We extracted, from 142 relevant records, 179 overall (622 stratified) seroprevalence measures, 4 overall proportions of HSV-1 in GUD and 64 overall (162 stratified) proportions of HSV-1 in genital herpes. Pooled mean seroprevalence was 67.4% (95% CI 65.5% to 69.3%) with 32.5% (95% CI 29.4% to 35.7%) of children and 74.4% (95% CI 72.8% to 76.0%) of adults infected. Pooled seroprevalence increased steadily with age, being lowest in those aged <20 years (39.3%, 95% CI 35.9% to 42.7%) and highest in those aged >50 years (82.9%, 95% CI 78.8% to 86.6%). Pooled seroprevalence decreased yearly by 0.99-fold (95% CI 0.99 to 1.00). Pooled mean proportion of HSV-1 detection was 13.6% (95% CI 4.1% to 27.1%) in GUD, 34.1% (95% CI 31.7% to 36.5%) in genital herpes and 49.3% (95% CI 42.2% to 56.4%) in first episode genital herpes. Pooled proportion of HSV-1 detection in genital herpes increased yearly by 1.01-fold (95% CI 1.00 to 1.02), with higher detection in women (42.0%, 95% CI 37.4% to 46.7%) than men (24.1%, 95% CI 19.8% to 28.6%).

Conclusions

HSV-1 epidemiology is transitioning away from its historical pattern of oral acquisition in childhood. Every year, seroprevalence is declining by 1% and the proportion of HSV-1 in genital herpes is increasing by 1%. As many as two-thirds of children are reaching sexual debut unexposed, and at risk of HSV-1 genital acquisition in adulthood.

Epidemiology of herpes simplex virus type 2 in Latin America and the Caribbean: systematic review, meta-analyses and metaregressions

Objective

To characterise epidemiology of herpes simplex virus type 2 (HSV-2) in Latin America and the Caribbean.

Methods

HSV-2 reports were systematically reviewed and synthesised, and findings were reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Meta-analyses and metaregressions were conducted.

Finding

102 relevant reports were identified including 13 overall incidence measures, 163 overall (and 402 stratified) seroprevalence measures, and 7 and 10 proportions of virus detection in genital ulcer disease and in genital herpes, respectively. Pooled mean seroprevalence was 20.6% (95% CI 18.7% to 22.5%) in general populations, 33.3% (95% CI 26.0% to 41.0%) in intermediate-risk populations, 74.8% (95% CI 70.6% to 78.8%) in female sex workers, and 54.6% (95% CI 47.4% to 61.7%) in male sex workers, men who have sex with men and transgender people. In general populations, seroprevalence increased from 9.6% (95% CI 7.1% to 12.4%) in those aged <20 years to 17.9% (95% CI 13.6% to 22.5%) in those aged 20–30, 27.6% (95% CI 21.4% to 34.2%) in those aged 30–40 and 38.4% (95% CI 32.8% to 44.2%) in those aged >40. Compared with women, men had lower seroprevalence with an adjusted risk ratio (ARR) of 0.68 (95% CI 0.60 to 0.76). Seroprevalence declined by 2% per year over the last three decades (ARR of 0.98, 95% CI 0.97 to 0.99). Pooled mean proportions of HSV-2 detection in GUD and genital herpes were 41.4% (95% CI 18.9% to 67.0%) and 91.1% (95% CI 82.7% to 97.2%), respectively.

Conclusions

One in five adults is HSV-2 infected, a higher level than other world regions, but seroprevalence is declining. Despite this decline, HSV-2 persists as the aetiological cause of nearly half of GUD cases and almost all of genital herpes cases.

Estimates of the Prevalence and Incidence of Genital Herpes, United States, 2018

BACKGROUND

Although there are more recent estimate of genital herpes prevalence, incidence estimates in the United States (US) have not been updated since 2008.

METHODS

We estimated genital herpes prevalence and incidence for 2018 among adults aged 18 to 49 years. We estimated prevalence using 2015-2018 National Health and Nutrition Examination Survey herpes simplex virus type 2 (HSV-2) seroprevalence data among the noninstitutionalized civilian population and extrapolated this prevalence to the full US population using 2018 American Community Survey data. We estimated incidence using 2011 to 2018 National Health and Nutrition Examination Survey HSV-2 data as inputs to a simple mathematical model. We used Monte Carlo simulation to generate 10,000 input parameter sets for age and sex subpopulations and summarized our estimates by their median; uncertainty intervals for these estimates are characterized by their first (Q1) and third (Q3) quartiles. We conducted sensitivity analyses investigating the impact of HSV type 1 (HSV-1) infection on estimates of genital herpes burden.

RESULTS

In 2018, there were an estimated 18.6 (Q1 = 18.1, Q3 = 19.0) million prevalent and 572,000 (Q1 = 479,000, Q3 = 673,000) incident genital herpes infections among 18- to 49-year-olds. Women accounted for two thirds of prevalent infections with an estimated 12.1 (Q1 = 11.9, Q3 = 12.5) million infections. Incidence was highest among 18- to 24-year-olds with an estimated 242,000 (Q1 = 210,000, Q3 = 274,000) infections. Sensitivity analyses indicated that HSV-1 could be responsible for millions more prevalent genital herpes infections, and tens of thousands of additional incident genital herpes infections, depending on the percentage of HSV-1 infections that are genital.

DISCUSSION

Genital herpes is a common sexually transmitted disease in the United States. Future research to understand the burden of genital infections attributable to HSV-1 would refine estimates of genital herpes burden.

Epidemiological Impact of Novel Preventive and Therapeutic HSV-2 Vaccination in the United States: Mathematical Modeling Analyses

This study aims to inform herpes simplex virus type 2 (HSV-2) vaccine development, licensure, and implementation by delineating the population-level impact of vaccination. Mathematical models were constructed to describe the transmission dynamics in presence of prophylactic or therapeutic vaccines assuming 50% efficacy, with application to the United States. Catch-up prophylactic vaccination will reduce, by 2050, annual number of new infections by 58%, incidence rate by 60%, seroprevalence by 21%, and avert yearly as much as 350,000 infections. Number of vaccinations needed to avert one infection was only 50 by 2050, 34 by prioritizing those aged 15-19 years, 4 by prioritizing the highest sexual risk group, 43 by prioritizing women, and 47 by prioritizing men. Therapeutic vaccination of infected adults with symptomatic disease will reduce, by 2050, annual number of new infections by 12%, incidence rate by 13%, seroprevalence by 4%, and avert yearly as much as 76,000 infections. Number of vaccinations needed to avert one infection was eight by 2050, two by prioritizing those aged 15-19 years, three by prioritizing the highest sexual risk group, seven by prioritizing men, and ten by prioritizing women. HSV-2 vaccination offers an impactful and cost-effective intervention to prevent genital herpes medical and psychosexual disease burden.

Frequency of depressive symptoms among female migrant workers in China: associations with acculturation, discrimination, and reproductive health

OBJECTIVES

Depression has been associated with numerous adverse health conditions. This study sought to determine the frequency of significant depressive symptoms and whether or not acculturative stress, discrimination, and reproductive health conditions were risk factors for significant depressive symptoms in migrant working women in China.

STUDY DESIGN

The design of this study is cross-sectional.

METHODS

Data were derived from a survey of female migrant workers at three employment sites in Changsha, China. The associations between acculturative stress, discrimination, reproductive health, and risk for significant depressive symptoms were obtained using F-tests for mean differences, correlations, ordinary least squares regression, and logistic regression analysis.

RESULTS

Between March and June 2017, 232 eligible female participants completed the survey among whom the median age was 34.36 years (standard error 0.43) and 25.58% reported significant depressive symptoms. Significant depressive symptoms were associated with higher education (F-test, P = .006), all four acculturative stress factors (r = 0.15 to r = 0.29), both institutional and interpersonal discrimination (r = 0.29, r = 0.35), age (r = - 0.13), and self-rated health (r = - 0.19). In multivariate regression analysis of depression scale scores, interpersonal discrimination was the strongest predictor (beta = 0.238, P = .002) among the nine factors identified in bivariate analysis. None of the other predictors (age, self-rated health, education, acculturative stress, and institutional discrimination) showed significant associations with the depression scale. Similar results were obtained for a multivariate logistic regression analysis of a clinically important threshold for depression (<10 versus ≥ 10 on the depression scale). Only interpersonal discrimination significantly distinguished between clinical depression categories (odds ratio = 2.607 per unit change in the index, P = .001).

CONCLUSIONS

Migrant women workers in China appear to be at risk for significant depressive symptoms, and interpersonal discrimination appears to be an important risk factor in this setting. Acculturative stress and institutional discrimination may also be relevant risk factors, as suggested in our bivariate analysis, but in our sample, the correlations between the stress and discrimination factors are high enough to compromise identification of unique associations between acculturation stress and depression. Government, community and workplace education, and psychosocial services for migrant women are recommended.

Characterizing the transitioning epidemiology of herpes simplex virus type 1 in the USA: model-based predictions

BACKGROUND

Herpes simplex virus type 1 (HSV-1) is a prevalent lifelong infection that appears to be undergoing an epidemiologic transition in the United States (US). Using an analytical approach, this study aimed to characterize HSV-1 transitioning epidemiology and estimate its epidemiologic indicators, past, present, and future.

METHODS

An age-structured mathematical model was developed to describe HSV-1 transmission through oral and sexual modes of transmission. The model was fitted to the National Health and Nutrition Examination Surveys, 1976-2016 data series.

RESULTS

HSV-1 seroprevalence was projected to decline from 61.5% in 1970 to 54.8% in 2018, 48.5% in 2050, and 42.0% in 2100. In < 3 decades, seroprevalence declined by > 30% for those aged 0-19 years, but < 5% for those aged > 60. Meanwhile, the number of new infections per year (oral and genital) was persistent at 2,762,000 in 1970, 2,941,000 in 2018, 2,933,000 in 2050, and 2,960,000 in 2100. Of this total, genital acquisitions contributed 252,000 infections in 1970, 410,000 in 2018, 478,000 in 2050, and 440,000 in 2100-a quarter of which are symptomatic with clinical manifestations. For those aged 15-49 years, nearly 25% of incident infections are genital. Most genital acquisitions (> 85%) were due to oral-to-genital transmission through oral sex, as opposed to genital-to-genital transmission through sexual intercourse.

CONCLUSION

HSV-1 epidemiology is undergoing a remarkable transition in the US, with less exposure in childhood and more in adulthood, and less oral but more genital acquisition. HSV-1 will persist as a widely prevalent infection, with ever-increasing genital disease burden.

Sexual Quality of Life and Association With HIV and Sexually Transmitted Infections Among a Cohort of Heterosexual Couples in Kenya

INTRODUCTION

Sexual quality of life (SQoL) is a critical component of sexual health and is understudied in Sub-Saharan African settings with endemic HIV and sexually transmitted infection (STI).

AIM

We sought to assess SQoL among heterosexual couples in Kisumu, Kenya, and how this was associated with HIV status, STIs, and sexual practices.

METHODS

This was a prospective cohort study of community-recruited couples. SQoL, HIV status, herpes simplex virus (HSV)-2 status, bacterial vaginosis (BV), sexual practices, and sociodemographics were measured at baseline, 6 months, and 12 months. Multivariable linear regression with random intercept was fitted separately for females and males, accounting for partner characteristics.

MAIN OUTCOME MEASURE

SQoL was assessed with an 18-item female and 11-item male survey.

RESULTS

From April 2014 through July 2016, 252 couples were enrolled, and followed up through September 2017. At baseline, women were median age 23 years, 10% HIV positive, 53% HSV-2 seropositive, and 22% with BV. At baseline men were median age 26 years, 12% HIV positive, 47% HSV-2 seropositive, and 56% circumcised. Mean SQoL was higher for men (88) than women (78), with consistent scores over time. In multivariable analysis (P < .05 each), SQoL Questionnaire-Female (SQoL-F) score was reduced with: male partner report that sex felt rougher than he would have liked (9.5-point decrease), female HSV-2 seropositivity (5.15-point decrease), female reported having dry vaginal sex (5.27-point decrease); among women with BV, SQoL-F score declined with recent sexual activity (8.27-point decrease) and increasing age (0.75-point decrease per 1 year increase in age). Age and recent sex did not affect SQoL-F for women without BV. SQoL Questionnaire-Male score was decreased 4.99 points if male was employed, 4.52 points if male reported multiple recent sex partners, and 29.5 points for HIV positive men whose female partner reported having sex when not in the mood. Men's SQoL increased by 0.84 points for each 1-U increase in female partner body mass index and 17.6 points for HIV positive men whose female partner reported recent sex with him.

CLINICAL IMPLICATIONS

Within sexual partnerships, men had greater SQoL than women, and the adverse impact of BV and STIs on SQoL was greater for women than men.

STRENGTH & LIMITATIONS

Research is needed to ensure relevant domains are measured in settings where measure of SQoL has not been validated, along with robust measures of physiologic and psychologic correlates.

CONCLUSION

More attention to SQoL as an outcome may strengthen interventions aimed at preventing HIV and STIs and improving sexual health holistically. Mehta SD, Nordgren RK, Agingu W, et al.

Review of mathematical models of HSV-2 vaccination: Implications for vaccine development

Development of a vaccine against herpes simplex virus type 2 (HSV-2), a life-long sexually-transmitted infection (STI), would be a major step forward in improving global sexual and reproductive health. In this review, we identified published literature of dynamic mathematical models assessing the impact of either prophylactic or therapeutic HSV-2 vaccination at the population level. We compared each study's model structure and assumptions as well as predicted vaccination impact. We examined possible causes of heterogeneity across model predictions, key gaps, and the implications of these findings for future modelling efforts. Only eight modelling studies have assessed the potential public health impact of HSV-2 vaccination, with the majority focusing on impact of prophylactic vaccines. The studies showed that even an imperfect prophylactic HSV-2 vaccine could have an important public health impact on HSV-2 incidence, and could also impact HIV indirectly in high HIV prevalence settings. Therapeutic vaccines also may provide public health benefits, though they have been explored less extensively. However, there was substantial variation in predicted population-level impact for both types of vaccine, reflecting differences in assumptions between model scenarios. Importantly, many models did not account for heterogeneity in infection rates such as by age, sex and sexual activity. Future modelling work to inform decisions on HSV vaccine development and implementation should consider cost-effectiveness, account for additional HSV-2 sequelae such as neonatal transmission, and model greater heterogeneity in infection rates between individuals, more realistic vaccine deployment, and more thorough sensitivity and uncertainty analyses.

Experiences of living with a sexually transmitted disease: an integrative review

PURPOSE

This integrative review describes experiences related to living with a sexually transmitted disease (STD).

DESIGN

The data search was conducted using the CINAHL, MEDLINE (Ovid), PsycINFO and PubMed databases between the years 2000 and 2016. A manual search was also used. The retrieved data consisted of 33 original articles which were analysed using deductive and inductive content analysis.

RESULTS

Based on the results, an infected person has a need for information about STDs and experiences emotions such as a loss of purity and control over his/her body. In addition, the ego of the infected person is wounded due to the infection. Concerns about the results of treatments, suffering side effects, and experiences of unprofessional behaviour by nursing staff are related to the treatment of an STD. Having an STD in everyday life means coping with a changing condition, but there are resources that can provide support. The quality of life can also be negatively affected by an STD, and a future with an STD can manifest different hopes and concerns. In relation to other people, an STD has a marked effect, especially concerning sexual relations. The person's sex life can fade away; however, it may remain as an enjoyable experience. The infected person may also adopt safer sexual behaviours or continue with a risk-taking behaviour.

CONCLUSION

The results of this review can be used in the development of nursing practices, as well as be used in the prevention of STDs.

Estimating seroprevalence of herpes simplex virus type 1 among different Middle East and North African male populations residing in Qatar

HSV‐1 epidemiology in the Middle East and North Africa (MENA) remains poorly understood. Our study aimed to measure HSV‐1 antibody prevalence (seroprevalence) and its age‐distribution among select MENA populations residing in Qatar. Sera were collected from male blood donors attending Hamad Medical Corporation 2013‐2015. A total of 2,077 sera were tested for anti‐HSV‐1 antibodies using HerpeSelect^® 1 ELISA IgG kits (Focus Diagnostics, Cypress, CA). Robust Poisson regression was conducted to estimate adjusted infection prevalence ratios. Country‐specific HSV‐1 seroprevalence was estimated for 10 national populations: 97.5% among Egyptians, 92.6% among Yemenis, 90.7% among Sudanese, 88.5% among Syrians, 86.5% among Jordanians, 82.3% among Qataris, 81.4% among Iranians, 81.4% among Lebanese, 80.5% among Palestinians, and 77.0% among Pakistanis. Age‐specific HSV‐1 seroprevalence was estimated for Egypt, the Fertile Crescent (Iraq, Jordan, Lebanon, Palestine, and Syria), and Qatar. Seroprevalence increased with age among Fertile Crescent and Qatari nationals. Seroprevalence increased from 70.0% among those aged ≤ 24 years up to 98.0% among those aged ≥55 years among Fertile Crescent nationals. Seroprevalence was consistently above 90% for all ages among Egyptians. HSV‐1 seroprevalence is high in MENA, though with some variation across countries. The seroprevalence appears to have declined among current young age cohorts compared to its levels a few decades ago.

Measuring Health and Quality of Life for Women Undergoing Testing and Screening for Chlamydia: A Systematic Review

BACKGROUND

Most economic evaluations of interventions to prevent or control curable sexually transmitted infections (STIs), such as chlamydia, have focused on the longer-term health impacts avoided. However, there is a range of qualitative evidence suggesting that those who think that they might have an STI and/or undergo testing can experience impacts on their quality of life (QoL) at the testing and diagnosis stage. A systematic review was undertaken to identify and evaluate studies that have measured QoL and sexual health for women undergoing testing and screening for chlamydia.

METHODS

A systematic review was conducted, with searches of 5 electronic databases up to the end of August 2013. Data on study characteristics, methods, and results were extracted using a standard template, and a narrative synthesis was undertaken.

RESULTS

Eight studies measuring QoL and sexual health were included. The included studies measured a variety of aspects of QoL and sexual health, with a focus on psychosocial well-being. A range of validated tools were used to measure health and QoL, and "bespoke" questions were also developed. Few significant differences were found with comparator groups using generic instruments, but some impacts were found using bespoke questions.

CONCLUSIONS

Although researchers have begun to examine the relationships between QoL and sexual health, there are limitations associated with the evidence available. There is, thus, a need for further research exploring sexual health and QoL for patients undergoing testing and screening for curable STIs, with a focus on analyzing the most appropriate methodological approaches in this context.

Predictors of the Sexual Well-being of Individuals Diagnosed with Herpes and Human Papillomavirus

Research suggests that having a sexually transmitted infection (STI) such as genital herpes and human papillomavirus (HPV) can negatively affect sexual well-being. However, there is little research examining factors associated with poorer sexual well-being among individuals with a STI. This study investigated the extent to which stigma experiences, individual characteristics, and STI characteristics were associated with multiple aspects of sexual well-being among individuals diagnosed with herpes and/or HPV. Participants were an average of 36 years old (SD = 11.58) and included 188 individuals with herpes and/or HPV who completed measures of sexual activity, sexual problems, and sexual cognitive-affective factors. The results showed that experiences of stigmatization were the most important predictors of sexual well-being. Participants who perceived were stigmatized by others as well as those who internalized negative social attitudes to a greater extent reported poorer sexual well-being across all dimensions, over and above individual and STI characteristics. The implications of these findings for sexual health professionals are discussed.

Associations between individual and relationship characteristics and genital herpes disclosure

Disclosure is often a challenge for individuals living with genital herpes. This study explores determinants of genital herpes disclosure with one's most recent sexual partner using an online questionnaire (n = 93). The majority of participants reported (80.4%) disclosure. Among non-disclosers, fear of negative partner reactions was the primary reason for non-disclosure. Age, relationship commitment, time in relationship, and expectations of partner's reaction were statistically significant predictors at the bivariate level. Reaction expectations and relationship commitment remained significant in the multivariate logistic regression model. Findings indicate that future disclosure research should focus on relationship context and managing negative expectations to increase disclosure.

Seroprevalence of HSV-1 and HSV-2 antibodies in Canadian women screened for enrolment in a herpes simplex virus vaccine trial

Herpes simplex virus 1 and 2 (HSV-1 and HSV-2) infections continue to be among the most common and unrecognized sexually transmitted infections in the world. Although treatable, HSV-1 and HSV-2 infections remain incurable. Hence, there is interest in the development of a vaccine to prevent genital herpes. As part of a multicentre, randomized, placebo-controlled trial to test such a vaccine, healthy women 18-30 years were enrolled as volunteers in several Canadian centres between 2005 and 2007. This study reports the seroprevalence of HSV-1 and HSV-2 antibodies in this group. A total of 2694 adult female volunteers in Canada with no known history of herpes simplex were screened for HSV antibodies using Western blot assay (the gold standard for diagnosis of HSV) for potential participation in a randomized, double-blind efficacy field trial of a herpes simplex vaccine. This trial provides a unique opportunity to examine the prevalence of antibodies to HSV-1 and of antibodies to HSV-2 in women with no known history of herpes simplex infection. The prevalence of antibodies to HSV-1 and to HSV-2 is compared with that found in previous Canadian studies that focused on a more general population. The overall seroprevalence of antibody to HSV-1 was 43%; that of HSV-2 was 2.5% and seropositivity to both was 2%. The prevalence of antibody to both HSV-1 and to HSV-2 increased with age. Seronegativity to both HSV-1 and HSV-2 was 56% in participating centres with populations under 250,000 and 46% in participating centres with populations over 250,000. Significant racial differences in seropositivity to HSV-1 and to HSV-2 were noted. The likelihood of participants being seropositive to HSV-1 and to HSV-2 was found to increase with age and to positively correlate with the population of the city in which they resided. Hypotheses are proposed to account for differences in racial seropositivity to HSV-1 and to HSV-2.

Exploring sexual health among female sexually transmitted disease clinic patients, San Francisco 2010

BACKGROUND

Current data on sexual health in the United States is limited, in part, because of a lack of measurement tools. It is difficult for programs to develop a holistic approach to improving sexual health that is data-driven and evaluable without a tool that encompasses sexual health beyond the absence of disease. The objective of this study was to understand possible factors associated with sexual health and reported differences in sexual health among women.

METHODS

We conducted a survey measuring sexual health among women seeking care at the municipal sexually transmitted disease (STD) clinic in San Francisco between January 25, 2010, and June 15, 2010. Records were matched on variables including basic demographics, reason for visit, symptoms at visit, history of an STD, and STD diagnosis at the visit.

RESULTS

A total of 822 women completed the questionnaire during the study period. Women reporting no recent sexual activity reported feeling more insecure, angry, isolated, and limited because of health compared with women with recent sexual activity. However, few differences were seen among women based on symptoms and diagnosis at visit.

DISCUSSION

Given the minimal differences based on symptoms and disease, this suggests that there are other factors that impact the quality of life and sexual health. Creating tools that can be used to measure sexual health is a necessary first step for programs to understand the sexual health of a community. More broad-based assessments of sexual health in a variety of populations will be critical to identifying points of intervention and progress toward success.

Genital herpes beliefs: implications for sexual health

STUDY OBJECTIVE

Genital herpes (HSV) is exceedingly common in the United States and women are disproportionally affected. This study aims to describe young women's beliefs about HSV and examine the correlates of those beliefs.

DESIGN

A 40-item Herpes Representation measure (HSV-RoSTD) and a demographic questionnaire were administered to a convenience sample of young women. Data analysis included descriptive statistics, t-tests and Pearson's correlations.

SETTING

Four women's health clinics and one large state university.

PARTICIPANTS

302 women aged 18-24 years.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Four dimensions of HSV representations (cause, identity, future perspective, and psychosocial consequences), age and STD testing history.

RESULTS

Nearly all (98%) believed that HSV would result in genital sores and 68% believed they could tell if their sexual partner had HSV. Most (89%) understood the longevity of HSV; however, 30% believed that they could take a pill to get rid of the infection, and 15% indicated that it was likely they would die from HSV. Negative beliefs about the psychosocial impact of HSV were common as 95% indicated they would be depressed and 90% indicated concern about sex and partner notification. Those who were younger and those who had never been tested for STDs believed a genital herpes infection is highly symptomatic. Finally, negative beliefs about the psychosocial consequences of HSV were associated with beliefs about HSV being symptomatic, having a negative impact on future health, and being associated with sexual risk behaviors.

CONCLUSIONS

Young women have misconceptions about HSV, particularly regarding the symptomatology and the role of HSV medication. Noteworthy concerns about the negative psychosocial consequences of an HSV diagnosis were also raised, all of which have implications for young women's sexual health.

HSV-2 Seroepidemiology and Risk Factors among Iranian Women: A Time to New Thinking

BACKGROUND

Genital herpes is a common sexually transmitted disease in many developed and developing countries mostly caused by Herpes simplex virus type 2 (HSV-2). This study determines the prevalence of HSV-2 infection between two groups of women with high and low risk behaviors.

METHODS

In this seroepidemiologic study, 362 women attending obstetrics and gynecology clinics as low risk group and 156 prisoners and drop in center resident women in Tehran as high risk group were enrolled. HSV infection was identified by serologic tests on blood samples.

RESULTS

The prevalence of IgG antibody in high risk group was significantly more than low risk women (26.3% vs. 2.5%). The prevalence of IgM antibody in high risk group was less than low risk group (3.8% vs. 7.1%) but the difference was not statistically significant. In high risk group, there was significant association between positive IgG and anal/oral sex, use of condom, smoking and drug addiction as well as genital pain, burning, itching, ulcer, dysuria, and history of genital infection. In low risk group, association between positive IgM and IgG test results and risky behaviors were not significant. There was significant association between IgM and genital itching, rash, and ulcer.

CONCLUSION

Relatively high seroprevalence of anti-HSV-2 IgG and high frequency of genital Herpes among high risk women necessitates regular screening and safe sex education programs. Moreover, risk of acute infection in this group should not be ignored and its distribution in Iranian population should be alarmingly concerned.

Psychosocial impact of a positive HSV-2 diagnosis on adults with unrecognized HSV-2 infection

OBJECTIVE

To evaluate the current research on the psychosocial impact of a positive herpes simplex virus type 2 (HSV-2) diagnosis on asymptomatic adults.

DESIGN AND SAMPLE

A structured review of PubMed, CINAHL, and MEDLINE resulted in 8 articles published between 2000 and 2008.

MEASURES

Articles were included if they investigated psychosocial reactions to HSV serological testing, including asymptomatic individuals, and used measurement instruments with adequate psychometric properties.

RESULTS

The studies included participants of various backgrounds, including individuals with a new HSV-2 diagnosis concurrently receiving human immunodeficiency virus treatment, students within a university setting, and an HMO population. Current research indicates that a diagnosis of HSV-2 does not result in persistent psychosocial morbidity. However, studies that assessed for more nuanced reactions noted an impact on quality of life related to herpes.

CONCLUSIONS

Further research is needed to confirm these findings among varied populations, to explore quality of life following HSV screening, and to identify the characteristics that may make particular individuals more susceptible to adverse psychological consequences.

Herpes simplex virus 2 ICP0 mutant viruses are avirulent and immunogenic: implications for a genital herpes vaccine

Herpes simplex virus 1 (HSV-1) ICP0⁻ mutants are interferon-sensitive, avirulent, and elicit protective immunity against HSV-1 (Virol J, 2006, 3:44). If an ICP0⁻ mutant of herpes simplex virus 2 (HSV-2) exhibited similar properties, such a virus might be used to vaccinate against genital herpes. The current study was initiated to explore this possibility. Several HSV-2 ICP0⁻ mutant viruses were constructed and evaluated in terms of three parameters: i. interferon-sensitivity; ii. virulence in mice; and iii. capacity to elicit protective immunity against HSV-2. One ICP0⁻ mutant virus in particular, HSV-2 0ΔNLS, achieved an optimal balance between avirulence and immunogenicity. HSV-2 0ΔNLS was interferon-sensitive in cultured cells. HSV-2 0ΔNLS replicated to low levels in the eyes of inoculated mice, but was rapidly repressed by an innate, Stat 1-dependent host immune response. HSV-2 0ΔNLS failed to spread from sites of inoculation, and hence produced only inapparent infections. Mice inoculated with HSV-2 0ΔNLS consistently mounted an HSV-specific IgG antibody response, and were consistently protected against lethal challenge with wild-type HSV-2. Based on their avirulence and immunogenicity, we propose that HSV-2 ICP0⁻ mutant viruses merit consideration for their potential to prevent the spread of HSV-2 and genital herpes.
