WHO global research priorities for sexually transmitted infections.

Sexually transmitted infections (STIs) are widespread worldwide and negatively affect sexual and reproductive health. Gaps in evidence and in available tools have long hindered STI programmes and policies, particularly in resource-limited settings. In 2022, WHO initiated a research prioritisation process to identify the most important STI research areas to address the global public health need. Using an adapted Child Health and Nutrition Research Initiative methodology including two global stakeholder surveys, the process identified 40 priority STI research needs. The top priorities centred on developing and implementing affordable, feasible, rapid point-of-care STI diagnostic tests and new treatments, especially for gonorrhoea, chlamydia, and syphilis; designing new multipurpose prevention technologies and vaccines for STIs; and collecting improved STI epidemiologic data on both infection and disease outcomes. The priorities also included innovative programmatic approaches, such as new STI communication and partner management strategies. An additional six research areas related to mpox (formerly known as monkeypox) reflect the need for STI-related research during disease outbreaks where sexual transmission can have a key role. These STI research priorities provide a call to action for focus, investment, and innovation to address existing roadblocks in STI prevention, control, and management to advance sexual and reproductive health and wellbeing for all.

Prevention of sexual transmission of mpox: a systematic review and qualitative evidence synthesis of approaches.

BACKGROUND: The ongoing multi-country mpox outbreak in previously unaffected countries is primarily affecting sexual networks of men who have sex with men. Evidence is needed on the effectiveness of recommended preventive interventions. To inform WHO guidelines, a systematic review and qualitative evidence synthesis were conducted on mpox preventive behavioural interventions to reduce: (i) sexual acquisition; (ii) onward sexual transmission from confirmed/probable cases; and (iii) utility of asymptomatic testing. METHODS: Medline, EMBASE, PubMed, Cochrane and WHO trial databases, grey literature and conferences were searched for English-language primary research published since 1 January 2022. A reviewer team performed screening, data extraction and bias assessment. A qualitative thematic synthesis explored views and experiences of engagement in prevention in individuals at increased risk. RESULTS: There were 16 studies: 1 on contact-tracing, 2 on sexual behaviour, and 13 on asymptomatic testing. Although MPXV was detected in varying proportions of samples (0.17%-6.5%), the testing studies provide insufficient evidence to fully evaluate this strategy. For the qualitative evidence synthesis, four studies evaluated the experiences of most affected communities. Preferences about preventive interventions were shaped by: mpox information; the diversity of sexual practices; accessibility and quality of mpox testing and care; and perceived cost to wellbeing. CONCLUSIONS: Evidence on the effectiveness of interventions to prevent the sexual transmission of mpox remains scarce. Limited qualitative evidence on values and preferences provides insight into factors influencing intervention acceptability. Given global and local inequities in access to vaccines and treatment, further research is needed to establish the effectiveness of additional interventions.

World Health Organization Enhanced Gonococcal Antimicrobial Surveillance Programme, Cambodia, 2023.

To determine antimicrobial susceptibility of Neisseria gonorrhoeae, we analyzed phenotypes and genomes of 72 isolates collected in Cambodia in 2023. Of those, 9/72 (12.5%) were extensively drug resistant, a 3-fold increase from 2022. Genomic analysis confirmed expansion of newly emerging resistant clones and ongoing resistance emergence across new phylogenetic backbones.

The novel 2024 WHO Neisseria gonorrhoeae reference strains for global quality assurance of laboratory investigations and superseded WHO N. gonorrhoeae reference strains-phenotypic, genetic and reference genome characterization.

OBJECTIVES: MDR and XDR Neisseria gonorrhoeae strains remain major public health concerns internationally, and quality-assured global gonococcal antimicrobial resistance (AMR) surveillance is imperative. The WHO global Gonococcal Antimicrobial Surveillance Programme (GASP) and WHO Enhanced GASP (EGASP), including metadata and WGS, are expanding internationally. We present the phenotypic, genetic and reference genome characteristics of the 2024 WHO gonococcal reference strains (n = 15) for quality assurance worldwide. All superseded WHO gonococcal reference strains (n = 14) were identically characterized. MATERIAL AND METHODS: The 2024 WHO reference strains include 11 of the 2016 WHO reference strains, which were further characterized, and four novel strains. The superseded WHO reference strains include 11 WHO reference strains previously unpublished. All strains were characterized phenotypically and genomically (single-molecule PacBio or Oxford Nanopore and Illumina sequencing). RESULTS: The 2024 WHO reference strains represent all available susceptible and resistant phenotypes and genotypes for antimicrobials currently and previously used (n = 22), or considered for future use (n = 3) in gonorrhoea treatment. The novel WHO strains include internationally spreading ceftriaxone resistance, ceftriaxone resistance due to new penA mutations, ceftriaxone plus high-level azithromycin resistance and azithromycin resistance due to mosaic MtrRCDE efflux pump. AMR, serogroup, prolyliminopeptidase, genetic AMR determinants, plasmid types, molecular epidemiological types and reference genome characteristics are presented for all strains. CONCLUSIONS: The 2024 WHO gonococcal reference strains are recommended for internal and external quality assurance in laboratory examinations, especially in the WHO GASP, EGASP and other GASPs, but also in phenotypic and molecular diagnostics, AMR prediction, pharmacodynamics, epidemiology, research and as complete reference genomes in WGS analysis.

Internalized Sexual Orientation Stigma and Mental Health in a Religiously Diverse Sample of Gay and Bisexual Men in Lebanon.

This study explores the correlates of internalized sexual orientation stigma, psychological distress and depression in a religiously diverse sample of gay and bisexual men in Lebanon. A convenience sample of 200 participants completed a cross-sectional survey. Bisexual men reported greater internalized sexual orientation stigma and less outness to their family and were more likely to face family pressure to have a heterosexual marriage than gay men. People of no religion reported more outness than Muslims and Christians but also higher psychological distress and depression. Multiple regression analyses showed that religiosity, outness, family pressure to marry and being bisexual were positively associated with internalized sexual orientation stigma; and that frequency of attending one's place of worship was negatively associated with psychological distress and depression. Individuals may be coping with adversity through engagement with institutionalized religion, which also appears to be a source of negative social representations concerning their sexuality.

Predicting sexual risk and sexual health screening in a sample of university students in Lebanon: a cross-sectional study.

OBJECTIVE: The present study focuses on factors that predict sexual risk behaviors and sexual health screening behaviors in a sample of university students in Lebanon. PARTICIPANTS: A convenience sample of 250 undergraduate students was recruited at a private university in Beirut, Lebanon. METHODS: Students completed measures of religiosity, psychological distress, contraceptives usage, human immunodeficiency virus (HIV)/sexually transmitted infections (STI) screening, and sexual risk behaviors. RESULTS: Religiosity was negatively associated with a range of risky sexual behaviors whereas psychological distress was positively associated with these behaviors. Sex under the influence of alcohol/drugs, discussing methods of contraception, and engaging in sexual activities later regretted had significant effects on having had condomless vaginal sex. Gender (being female) and sex under the influence of alcohol had significant effects on STIs screening. CONCLUSION: Interventions that focus on managing drug and alcohol use in students, unwanted pregnancy, religion, stigma related to screening, and sexual health education are recommended.

Beneficial UVB phototherapy preceding a fractional CO2 laser-UVB protocol in refractory non-segmental vitiligo.

OBJECTIVES: To explore the short- and long-term effects of UVB phototherapy preceding a fractional CO2 laser-UVB protocol in patients with resistant nonsegmental vitiligo. MATERIALS AND METHODS: This single-center, prospective, split-face/body, evaluator-blinded study included adult patients with stable vitiligo refractory to conventional treatments. Two symmetrical lesions were selected. Phototherapy was delivered with one side covered, until minimal erythema. Within 3 days, 31-month-apart sessions of laser were performed on both sides. After each laser session, phototherapy was resumed three times weekly, with all lesions uncovered, until 8 weeks after the last laser session. At baseline, at the end of treatment, and 5 years later, a Mean Improvement Score by Physician (MISP) and a patient satisfaction 10-point visual analog score (VAS) were recorded. RESULTS: Ten patients (8 women and 2 men) were included; their mean age was 32.9 years; phototype III was predominant; the mean duration of vitiligo was 3 years. At the end of treatment and 5 years later, scores of lesions treated with UVB-CO2 -UVB (mean MISP 3.0 and 2.9, mean ΔVAS 4.5 and 3.9, respectively), were higher than those of lesions treated only with CO2 -UVB (mean MISP 2.5 and 2.4, mean ΔVAS 4.1 and 3.6, respectively). After 5 years, one patient lost his partial response and two patients developed light hyperpigmentation on both sides. CONCLUSION: Exposure to UVB before CO2 -UVB explains the higher scores as it was the only variable between the two sides. It may improve the response of resistant lesions with a constantly sustained result over 5 years.

Big toenail onychomycosis features associated with response to 1064 nm Nd: YAG laser treatment.

BACKGROUND: A few studies discussed the factors correlated to response in laser treatment of onychomycosis. OBJECTIVE: This study aimed to seek big toenail onychomycosis features that correlate with response to 1064 nm Nd: YAG laser treatment. METHODS: This single-center, retrospective study included patients who had only one big toenail onychomycosis, with a confirmed mycological diagnosis and/or a high clinical suspicion. Patients had three sessions 1 month apart. The following characteristics were collected from the patients' files: age, sex, smoking and arterial hypertension statuses, results of baseline mycological culture, Onychomycosis Severity Index (OSI) score at baseline and at the end of the 6-month follow-up, as well as the reported side effects. RESULTS: We included 105 patients, 86 women and 19 men, with a mean age of 43 years. Demographics have shown that 73.6% of patients were smokers, 17.9% had arterial hypertension, 61.9% had a culture positive for Trichophyton species, and 9.4% had a culture positive for Candida species. According to the OSI score, onychomycosis was mild in 18.9%, moderate in 39.6%, and severe in 41.5% of patients. At 6 months, clinical cure was achieved in 57.1% of patients. CONCLUSION: The OSI decrease after 3 sessions of Nd: YAG laser was significantly more important in women and in patients with positive mycology culture, smaller affected area of the nail, no subungual hyperkeratosis, and no nail matrix involvement. Age, smoking, hypertension, and side effects were not shown to significantly correlate with the decrease of the OSI score.

Community-led HIV self-testing for men who have sex with men in Lebanon: lessons learned and impact of COVID-19.

BACKGROUND: In Lebanon, HIV is concentrated in both native and refugee communities of men who have sex with men (MSM). For over 10 years, the National AIDS Program (NAP) has offered HIV voluntary counselling and testing through a partnership with nongovernmental organizations (NGOs). In 2018, implementation of HIV self-tests (HIVST) was introduced, and this self-care intervention has been further scaled up during the coronavirus disease 2019 (COVID-19) pandemic. This paper (1) describes the effectiveness of implementing HIVST in Lebanon, and (2) discusses how the success of HIVST implementation has been reflected during the COVID-19 pandemic. METHODS: The NAP conducted a series of workshops (July-November 2018) to introduce HIVST services for healthcare workers working at different NGOs. The workshops highlighted that HIVST would be distributed for free, that it would be confidential and voluntary, and that participants were encouraged to notify the NGOs of their results, which would be kept strictly confidential. NGOs collected data anonymously and confidentially from beneficiaries (age, consistency of condom use and HIV testing history), who were asked to call back with the results of their HIVST. At the NAP, data were combined, aggregated and analysed. RESULTS: In 2019, the NGOs distributed 1103/1380 (79.9%) HIVST kits to their beneficiaries. The NGOs collected feedback on 111 kit results, of which two were HIV-positive. Feedback about HIVST results from beneficiaries was low (111/1103) due to noncompliance of beneficiaries and the lack of human and financial resources in the NGOs. From January through May 2020, a total of 625/780 HIVST kits (80.1%) were distributed. This period was divided into pre-COVID-19 and during COVID-19. The follow-up with the beneficiaries during COVID-19 was much improved because of the absence of on-site activities, shifting more efforts towards HIVST (449/625). There have been no reports of social harm related to HIVST. CONCLUSION: HIVST implementation in Lebanon serves as an example of introducing a self-care intervention as part of a community-led effort. In order to maintain HIVST services at the same improved level, reorganization of care is needed within each NGO following the adaptation process due to COVID-19, along with continuous monitoring and evaluation of HIVST reported data.

Dermoscopy for venereologists: an update on patterns of tumors, inflammatory and infectious diseases of the genitalia, and tips for differential diagnosis.

INTRODUCTION: Dermoscopy is an integrative part of clinical dermatologic examination. For clinicians mainly dealing with genital dermatoses and other venereal diseases, the differential diagnosis includes a broad spectrum of neoplastic, inflammatory, and infectious entities. Dermoscopy might have a valuable role to enhance the clinical differential diagnosis and help avoid some biopsies done for diagnostic purposes. Although the dermoscopic patterns of most tumors and inflammatory diseases of the trunk/face have been described, their manifestations on genital areas are less elucidated. We aimed to provide a succinct summary of existing data on dermoscopy of dermatologic diseases on genital areas. METHODS: A literature search was performed on PubMed using the terms dermoscopy OR dermatoscopy OR videodermoscopy OR video dermoscopy AND genital. All studies reporting on dermoscopic findings of at least one case of a dermatologic disease on genital areas were included in the review. Unless otherwise indicated, ×10 was the magnification used in the reported studies. The main outcome was to describe the dermoscopic feature of each disease. RESULTS: A total of 31 articles were identified and analyzed. They included single case reports and case series. The described entities were categorized into anatomical variants, vascular and lymphatic lesions, tumors, inflammatory disorders, and infectious conditions. CONCLUSION: In diseases of the genital area, dermoscopic findings can be highly diagnostic and might establish a confident diagnosis. Limitation is that most of the criteria are based on case series, and few of them have been validated.

A case of Mycoplasma genitalium possible resistance in a woman.

Mycoplasma genitalium (MG) is an increasingly recognized sexually transmitted infection. In women, MG is particularly associated with endometritis, cervicitis, pelvic inflammatory disease, HIV, and long-term negative reproductive health and obstetric outcomes. In addition, MG has the potential to show resistance to antibiotics. We present here a case of possibly resistant MG in Lebanon, where MG prevalence and MG antibiotic resistance status are unknown.

Antiretroviral-responsive confluent and reticulated papillomatosis: a case report of an unusual association.

This is the case of a 29-year-old male newly diagnosed with advanced HIV (CD4 < 35cells/mm3), presenting to us with hyperpigmented and scaly non-pruritic macules over his chest and upper abdomen of several weeks duration. Woodlamp examination was negative, but a skin biopsy suggested confluent and reticulated papillomatosis (CRP). Given his lack of any of the condition's identifiable triggers and the unusually rapid resolution of his lesions shortly after antiretroviral therapy initiation, an immunodeficiency-related etiology for his CRP was entertained. Autoimmune disorders and atopic conditions have been well reported previously as possible triggers of CRP. However, in this report, we raise immunodeficiency as a possible trigger of CRP as well, such that immune dysregulation overall (autoimmunity or immunodeficiency) can contribute to CRP ontogenesis. To our best knowledge, this is the first report to date suggesting a possible association between CRP, a rare dermatological condition, and acquired immunodeficiency syndrome.

Onychoscopic evaluation of distal and lateral subungual onychomycosis: A cross-sectional study in Lebanon.

BACKGROUND AND PURPOSE: The aim of this study was to evaluate the onychoscopic patterns associated with distal lateral subungual onychomycosis (DLSO) in Lebanon. MATERIALS AND METHODS: The present study was conducted on 45 patients with clinical DLSO attending two dermatology clinics in Beirut, Lebanon, between January 2018 and April 2018. The patients were subjected to dermoscopy to identify the onychoscopic patterns. RESULTS: The DLSO was predominantly associated with white, yellow, and brown color changes (P<0.05). Dermoscopic patterns of longitudinal striae (n=31; 68.75%), spiked pattern (n=25; 55.5%), and jagged pattern (n=25; 55.5%) were significantly correlated with DLSO (P<0.001). Our findings are in accordance with five previous reports in which dermoscopic findings are discussed in onychomycosis. CONCLUSION: It is recommended to perform further studies on homogeneous groups with different clinical subtypes of onychomycosis including patients with suspected traumatic onycholysis or other nail diseases. Identification of onychoscopic patterns would offer the clinicians a quick, simple, and complementary tool for the diagnosis of onychomycosis.
