Genital herpes stigma: Toward the Measurement and Validation of a highly prevalent yet hidden public health problem

Herpes Simplex Type 1 as the Predominant Cause of Genital Herpes in College Students

BACKGROUND

Genital herpes etiology has been shifting to include a greater proportion of herpes simplex virus type 1 (HSV-1) infection in the last few decades. A prior study published in 2003 found that 48.9% of infections in a college health population were HSV-1.

METHODS

We evaluated the number of positive HSV polymerase chain reaction test results obtained from anogenital sites from undergraduate and graduate students from 2013 to 2022 in a college health clinic setting and analyzed the number caused by HSV-1 and HSV type 2 and compared by sex. This was then compared with the prior study from 1993 to 2001.

RESULTS

We received 691 (of 2685 samples) positive polymerase chain reaction results for HSV of both types in the period analyzed. Overall, 600 (86.8%) of these were HSV-1, and 520 (75.2%) were in female patients. The prior study in 1993 to 2001 found that 48.9% (244 of 675) of all positive test results were HSV-1; we observed an increase in the percentage of positive HSV-1 over all positive test results of 1.8 ( χ2 = 16.548; P < 0.001).

CONCLUSIONS

Our study shows that 86.8% of the positive genital HSV test results from 2013 to 2022 were HSV-1. This shows that most positive HSV test results in this setting are now HSV-1, a substantial increase from the previous study in our clinic.

Psychoeducational interventions for people living with chronic communicable disease: a systematic review

OBJECTIVE

Psychoeducation is increasingly recognised for its value in facilitating adaption to a chronic disease diagnosis. This study aimed to synthesise available literature on the psychoeducation interventions available to adults living with chronic communicable disease.

METHODS

PubMed, CINAHL, Embase, SocINDEX, PsycINFO and PsycArticles were systematically searched up to May 2023. Peer-reviewed studies, published in English, investigating the impact of psychoeducational interventions on adults living with chronic communicable disease were included, across a range of outcome measures. Narrative synthesis was performed. The Effective Public Health Practice Project tool and Critical Appraisal Skills Programme tool were used to assess risk of bias.

RESULTS

In total, 22 studies were included in the review. The majority (n=16) of study populations focused on people living with HIV, followed by hepatitis C (n=5) and genital herpes (n=1). Interventions were delivered online (n=2), via telephone (n=1) and in-person (n=19). The majority of interventions were delivered in group sessions (n=16) and studies emphasised the value of group cohesion for social support, encouraging participants to share their own knowledge in addition to standard didactic presentations. Four studies facilitated peer-led delivery of the psychoeducation. Studies aiming to improve psychological well-being were beneficial in reducing depressive symptoms and/or emotional distress or showed improvement in the participant group overall. There was some evidence to suggest psychoeducation can improve readiness to attend treatment and medication adherence.

CONCLUSION

The findings of this review highlight potential benefits of psychoeducation but indicate more robust clinical trials will be required to examine their effectiveness and elucidate the mechanisms by which they best operate. Future interventions incorporating a broader focus on resilience enhancement and coping skills specific to stigmatisation could more comprehensively serve the needs of adults living with chronic communicable disease, particularly with HIV. The role of peer support in group psychoeducation merits further exploration.

Diagnostic Methods and Management Strategies of Herpes Simplex and Herpes Zoster Infections

Herpesviruses are medium-sized double-stranded DNA viruses. Of more than 80 herpesviruses identified, only 9 human herpesviruses have been found to cause infection in humans. These include herpes simplex viruses 1 and 2 (HSV-1 and HSV-2), varicella-zoster virus (VZV), human cyto-megalovirus (HCMV), Epstein-Barr virus (EBV), and human herpesvirus (HHV-6A, HHV-6B, HHV-7, HHV-8). HSV-1, HSV-2, and VZV can be problematic given their characteristic neurotropism which is the ability to invade via fusion of its plasma membrane and reside within neural tissue. HSV and VZV primarily infect mucocutaneous surfaces and remain latent in the dorsal root ganglia for a host's entire life. Reactivation causes either asymptomatic shedding of virus or clinical manifestation of vesicular lesions. The clinical presentation is influenced by the portal of entry, the immune status of the host, and whether the infection is primary or recurrent. Affecting 60% to 95% of adults, herpesvirus-associated infections include gingivostomatitis, orofacial and genital herpes,and primary varicella and herpes zoster. Symptomatology, treatment, and potential complications vary based on primary and recurrent infections as well as the patient's immune status.

Genital Herpes Disclosure Attitudes Among Men Who Have Sex with Men

An abundance of literature interested in sexually transmitted infections-related disclosure attitudes among MSM (men who have sex with men) exists. However, comparatively few studies have examined these with respect to genital herpes. This cross-sectional study examined attitudes about herpes-related disclosure among Houston MSM. Convenience sampling at Houston-based MSM venues and events was conducted during December 2018 and January 2019 with 302 participants recruited. Participants were asked if an individual with genital herpes should disclose to others and if they would disclose to others if they had/have genital herpes. Factors associated with decreased belief that someone should disclose a genital herpes infection to others were history of genital herpes (OR 0.14, 95% CI [0.04, 0.55]) and race other than white, black, or Hispanic/Latino (OR 0.34, 95% CI [0.15, 0.77]). History of 0 to 1 sexual partner(s) in the past year was associated with increased belief that an individual should disclose (OR 2.43, 95% CI [1.19, 4.98]), while self-reported history of genital herpes was associated with decreased intent to disclose one's own infection to potential partners (OR 0.30, 95% CI [0.10, 0.91]). Self-reported history of genital herpes was associated with decreased belief that someone with genital herpes should tell others and with decreased likelihood to disclose one's own status. Lastly, race other than white, black, or Hispanic/Latino was associated with increased belief that someone with genital herpes should not tell others. Normalization of genital herpes could bolster intent to disclose genital herpes infection and improve sexual outcomes.

Machine Learning for Risk Group Identification and User Data Collection in a Herpes Simplex Virus Patient Registry: Algorithm Development and Validation Study

BACKGROUND

Researching people with herpes simplex virus (HSV) is challenging because of poor data quality, low user engagement, and concerns around stigma and anonymity.

OBJECTIVE

This project aimed to improve data collection for a real-world HSV registry by identifying predictors of HSV infection and selecting a limited number of relevant questions to ask new registry users to determine their level of HSV infection risk.

METHODS

The US National Health and Nutrition Examination Survey (NHANES, 2015-2016) database includes the confirmed HSV type 1 and type 2 (HSV-1 and HSV-2, respectively) status of American participants (14-49 years) and a wealth of demographic and health-related data. The questionnaires and data sets from this survey were used to form two data sets: one for HSV-1 and one for HSV-2. These data sets were used to train and test a model that used a random forest algorithm (devised using Python) to minimize the number of anonymous lifestyle-based questions needed to identify risk groups for HSV.

RESULTS

The model selected a reduced number of questions from the NHANES questionnaire that predicted HSV infection risk with high accuracy scores of 0.91 and 0.96 and high recall scores of 0.88 and 0.98 for the HSV-1 and HSV-2 data sets, respectively. The number of questions was reduced from 150 to an average of 40, depending on age and gender. The model, therefore, provided high predictability of risk of infection with minimal required input.

CONCLUSIONS

This machine learning algorithm can be used in a real-world evidence registry to collect relevant lifestyle data and identify individuals' levels of risk of HSV infection. A limitation is the absence of real user data and integration with electronic medical records, which would enable model learning and improvement. Future work will explore model adjustments, anonymization options, explicit permissions, and a standardized data schema that meet the General Data Protection Regulation, Health Insurance Portability and Accountability Act, and third-party interface connectivity requirements.

Genital herpes - diagnosis, treatments, attitudes and response to disclosure amongst members of the UK Herpes Viruses Association

A diagnosis of genital herpes may result in psychological as well as physical morbidity. Many patients require on-going help and contact the Herpes Viruses Association (HVA), a UK patient support organisation. The HVA conducts occasional questionnaires relating to various issues surrounding herpes and this study reports on a survey conducted amongst members in 2015. The survey was done using SurveyMonkey and covered diagnosis/treatment, both allopathic and self-help, physical and psychological impact and disclosure to partners. Three hundred and fifty-eight women and 103 men completed the questionnaire. Male respondents were older than women (48.6 versus 42.9 years). The majority were first diagnosed in sexual health clinics. A high proportion had informed partners about the diagnosis and in 83% disclosure did not result in rejection. 57% were taking prophylaxis with more taking treatment episodically rather than continually; 11.3% sourced medications on-line. Alternative treatments were used commonly with Lomaherpan cream (Melissa officinalis), lidocaine ointment and a diet with reduced arginine and increased lysine the most frequent choices. Other alternative treatments included olive leaf extract, Eleuthercoccus senticosus and vitamin supplements. Women reported being troubled psychologically more than men. Neuropathic pain was reported by 80.4% of the women and 64.1% of the men. Although antiviral treatment is cheap and well-tolerated it is still being refused by some healthcare providers. There still appears to be a considerable degree of stigma experienced by patients which can be mitigated by support from patients' support groups such as the HVA.
