The European response to control and manage multi- and extensively drug-resistant Neisseria gonorrhoeae

Because cefixime and ceftriaxone resistance in Neisseria gonorrhoeae and gonorrhoea treatment failures were increasing, a response plan to control and manage multidrug-resistant N. gonorrhoeae (MDR-NG) in Europe was published in 2012. The three main areas of the plan were to: (i) strengthen surveillance of antimicrobial resistance (AMR), (ii) implement monitoring of treatment failures and (iii) establish a communication strategy to increase awareness and disseminate AMR results. Since 2012, several additional extensively drug-resistant N. gonorrhoeae (XDR-NG) strains have emerged, and strains with high-level ceftriaxone resistance spread internationally. This prompted an evaluation and review of the 2012 European Centre for Disease Prevention and Control (ECDC) response plan, revealing an overall improvement in many aspects of monitoring AMR in N. gonorrhoeae; however, treatment failure monitoring was a weakness. Accordingly, the plan was updated in 2019 to further support European Union/European Economic Area (EU/EEA) countries in controlling and managing the threat of MDR/XDR-NG in Europe through further strengthening of AMR surveillance and clinical management including treatment failure monitoring. The plan will be assessed biennially to ensure its effectiveness and its value. Along with prevention, diagnostic, treatment and epidemiological surveillance strategies, AMR surveillance is essential for effective control of gonorrhoea.     

Testing rates for sexually transmitted infections among HIV-infected men who have sex with men attending two different HIV services

This study compares the testing rates of bacterial sexually transmitted infections (STIs) among HIV-positive men who have sex with men (MSM) attending two HIV clinics in Melbourne. Data on STI testing over a 12-month period were obtained for all HIV-positive MSM who attended the clinics between January and March 2006. Screening rates for bacterial STIs were significantly higher at a sexual health clinic (n = 254) compared with an infectious diseases clinic (n = 351), whether this was measured according to: at least one STI test being performed for chlamydia, gonorrhoea or syphilis (69% vs. 38%, P < 0.01); serological testing for syphilis alone (67% vs. 34%, P < 0.01); or 'complete' STI screening for pharyngeal gonorrhoea, urethral chlamydia, anal gonorrhoea, anal chlamydia and syphilis (41% vs. 6%, P < 0.01). Substantial differences in STI testing rates among HIV-positive MSM may exist between HIV clinical services depending on the measures in place that promote STI screening.     

Different trends for different sexually transmissible infections despite increased testing of men who have sex with men

Australian and New South Wales Sexually Transmissible Infections Strategies recommend sexual health clinics actively target particular populations, including men who have sex with men (MSM), who have increasing rates of sexually transmitted infections (STIs). We describe trends in MSM attendances, STI testing and diagnostic yield from 1996 to 2007 at a Sydney public sexual clinic. Aggregate data were extracted from the clinic database. There was a 76% increase in the number of individual MSM attending, more than three-fold increase in the number of STI tests performed and the proportion of MSM tested. The increase in testing was greatest for rectal infections. The positive yield increased for rectal chlamydia and infectious syphilis; remained stable for pharyngeal gonorrhoea; and decreased for urethral gonorrhoea, rectal gonorrhoea and urethral chlamydia. Our results demonstrate successful service reorientation in response to a local STI epidemic. Differing trends suggest evolving transmission dynamics for different STIs in the context of increased testing of asymptomatic MSM.     

Test Not Talk screening for asymptomatic men

This audit reviews the first year's experience within a rapid comprehensive sexually transmitted infection (STI) and HIV screening for asymptomatic men in a small-integrated sexual health clinic in outer London. Men requesting STI/HIV screening only were offered symptom self-assessment, blood tests for syphilis and HIV, and first void urine tests for chlamydia and gonorrhoea. Of 468 available appointments, 337 were made (72%) and 303 were kept (80%). Of the 303 attendances, 264 (87%) were first-ever attendances. Of the 303 men seen, 295 (97.4%) underwent chlamydia and gonorrhoea testing, while 246 (80.9%) were tested for syphilis and HIV. No new HIV diagnoses were made. One patient was diagnosed with late latent syphilis and one had asymptomatic gonorrhoea, while 20 (6.6%) diagnoses of chlamydia were made. We believe that Test Not Talk clinics offer a good approach to rapid screening of asymptomatic men and to meet their sexual health needs.     

Enhanced surveillance of hepatitis C in the EU, 2006 – 2012

Hepatitis C is a major public health issue across Europe, and with rapidly evolving developments in the therapeutic field, it is essential that countries have access to epidemiological information. In 2011, The European Centre for Disease Prevention and Control (ECDC) introduced enhanced surveillance of hepatitis C across EU/EEA countries collecting routine data from national notification systems using standardized case definitions. Data collected from 2006 to 2012 indicate a high burden of disease with great variation in reported cases between countries. Most cases occurred among young adult males, and although injecting drug use dominated across all cases, there were increasing numbers of acute cases reported among men who have sex with men. Geographically, the reported data were the inverse of what may be expected based on findings from recent prevalence surveys in a number of EU/EEA countries. Unexpectedly, low figures were reported through notification systems in some southern and eastern European countries where prevalence is known from surveys to be high. This discrepancy highlights the limitation of surveillance data for a disease such as hepatitis C which is largely asymptomatic until a late stage, so that notifications reflect testing practices rather than real occurrence of disease. Further improvements to the quality of the data are important to increase data utility. Improved understanding of national testing practices is necessary to allow a better interpretation of surveillance results. Additional epidemiological studies alongside routine case‐based reporting in notification systems should also be considered to better estimate the true disease burden across Europe.     

Declining sexually transmitted infections among female sex workers: the results of an HIV and sexually transmitted infection prevention strategy in Honduras, 2006-08

In 2006, we implemented an HIV and sexually transmitted infection (STI) prevention programme for female sex workers (FSWs) in three Honduran cities. All FSW attending STI clinics underwent regular examinations and STI testing. Information on condom use with different partners was collected at each visit. After three years, we detected a significant decline in the prevalence of syphilis from 2.3% at the first screening to 0.0% at the third screening (P = 0.05), and of chlamydia, from 6.1% to 3.3% (P = 0.01). No changes were observed in the prevalence of gonorrhoea or trichomoniasis. The cumulative HIV prevalence remained constant (P = 0.44). Reports of condom use with clients increased from 93.8% to 98.9% (P < 0.001). The implementation of an HIV/STI prevention programme in FSW has contributed to increases in condom use with clients and the reduction in syphilis and chlamydia prevalence. The intervention should be strengthened and considered as part of a national health policy strategy.     

Syphilis and gonorrhoea in the Czech Republic

Syphilis remains a public health problem in the Czech Republic and worldwide. The Czech Republic--until 1993 a part of Czechoslovakia--has a long tradition in public health activities, and STI surveillance is mainly focused on the infections traditionally called venereal diseases--syphilis, gonorrhoea, chancroid, and lymphogranuloma venereum. Campaigns from the early 1950s, were successful in controlling syphilis and gonorrhoea; and chancroid and lymphogranuloma venereum infections are extremely rare. In late 1980s, a low incidence of newly reported syphilis cases was achieved (100-200 cases annually), while around 6500 cases of gonorrhoea were recorded annually during the same period. Health care and prevention of STI diseases in the Czech Republic are based on close cooperation between clinical departments and laboratory and epidemiological services of Environmental Health Offices. Annual statistics showing data on reported cases of 'venereal diseases', based on ICD-10 codes, are available from 1959. Separate statistical data on other STIs are not available, and aggregated numbers only for Chlamydia trachomatis infections have been presented annually since 2000. Following the political and social changes in the Czech community in 1989, a distinct increase of syphilis was recorded. Between 50% and 60% of notified cases were classified as late latent or of unknown duration. The continuing annual occurrence of congenital syphilis (7-18 cases per year) reported during the 1990s has also been a very serious phenomenon. Cases have been concentrated in large urban areas with a high level of commercial sex activity, and a high proportion of cases is also noted in refugees. While the annual incidence of gonorrhoea gradually decreased from 1994 to 2001 (from 28.5 to 8.9 per 100,000 population), the incidence of syphilis increased in this period from 3.6 to 9.6 per 100,000 population (the highest value was 13.4 in 2001) and in 2000, for the first time in many years, it exceeded the incidence of gonorrhoea.     

Syphilis surveillance and trends of the syphilis epidemic in Germany since the mid-90s

Recent surveillance reports from Europe and the United States show an increase in syphilis cases. Accurate epidemiological information about the distribution of syphilis is important for targeting screening and intervention programmes. The German syphilis notification system changed in 2001 from physician to laboratory-based reporting, which is complemented by a newly introduced sexually transmitted infection (STI) sentinel system. After reaching an all time low during the 1990s, syphilis notifications have increased significantly since 2001, coinciding with the introduction of the new reporting system. However, the increased reported incidence is reflecting a true rise in the number of cases and is not predominantly determined by more underreporting through the previous reporting system. The increase reflects syphilis outbreaks among men who have sex with men (MSM). The first of these outbreaks was observed in Hamburg in 1997. In 2003, incidence in men was ten times higher than in women. An estimated 75% of syphilis cases are currently diagnosed among MSM. A high proportion (according to sentinel data, up to 50%) of MSM diagnosed with syphilis are HIV positive. The continuously high number of syphilis cases diagnosed among heterosexuals in Germany in recent years compared with other western European countries may reflect the higher population movement between Germany and syphilis high incidence regions in south-east and eastern Europe.     

The three-year positivity rate of sexually transmitted infections among a group of HIV-infected men attending the Department of Genitourinary Medicine, Edinburgh, UK

The aim of this study was to investigate the prevalence of sexually transmitted infections (STI) among patients at the time of and subsequent to the diagnosis of HIV, and possible immunological or virological features of patients with STI. An observational study was carried out on the results of annual STI screenings conducted on consecutive HIV-infected men in the Department of Genitourinary Medicine, Edinburgh between 1 January 1999 and 1 January 2003. Patients were tested for syphilis, gonococcal, and chlamydial infections.Among the 79 male patients in the study cohort, the frequencies of all STI rose within the study period. The three-year positivity rates of episodes of gonorrhoea, chlamydia, and syphilis were (42/131) 32%, (21/127) 16%, and (13/150) 9%, respectively. Patients with STI had significantly higher median CD4+ T-cells (P<0.02) and lower median viral loads (P<0.0001), and a higher proportion of them were on highly active anti-retroviral therapy (HAART) (P<0.0002) compared with those without an STI. Routine screening for STI and counselling for safe sex should be part of care for all HIV-infected patients.     

HIV, Sexually Transmitted Infections, and Sexual Risk Behavior Among Transgenders in Indonesia

Behavioral surveillance was undertaken among 1,150 male-to-female transgenders (waria) in Java, Indonesia, 2007; samples were collected for HIV and STI testing (n?=?748). Almost all waria had ever sold sex (median duration 10?years). Prevalence of HIV was 24.4%, syphilis 26.8% and rectal gonorrhea and/or chlamydia 47.0%. Syphilis and rectal STIs were associated with HIV infection. Consistent condom use during receptive anal sex with clients was reported by 35.9% waria and was higher among those who visited an STI clinic and who knew their HIV status. Efforts should continue to strengthen behavior change and STI care in future HIV prevention programs.     

A systematic review and meta-analysis of the prevalence of chlamydia, gonorrhoea and syphilis in incarcerated persons

Communicable diseases are common in people who are incarcerated. We aimed to define the prevalence of chlamydia, gonorrhoea and syphilis in people who are incarcerated and to identify subgroups with the highest risk of infection. We searched for prevalence studies of chlamydia, gonorrhoea or syphilis in incarcerated populations. Pooled estimates were generated, and meta-regression was conducted. Random effects models yielded pooled prevalence estimates of 5.75% (95% confidence interval [CI] 5.01, 6.48) and 12.31% (95% CI 10.61, 14.01) for chlamydia in men and women, 1.4% (95% CI 1.09, 1.70) and 5.73% (4.76, 6.69) for gonorrhoea in men and women, and 2.45% (95% CI 2.08, 2.82) and 6.10% (95% CI 4.75, 7.46) for syphilis in men and women, respectively. Each infection was associated with female gender in meta-regression models. Chlamydia, gonorrhoea and syphilis are highly prevalent in these populations. Primary and secondary prevention efforts could improve individual and population health.     

STI/HIV Testing and Prevalence of Gonorrhea and Chlamydia Among Persons with Their Specified-Type Sex Partner

BackgroundPrevious studies have shown that sexually transmitted infections (STI) and human immunodeficiency virus (HIV) testing has varied, but STI prevalence was not estimated among patients during their health care visits in which a high-risk sexual partnership was documented. This study estimated gonorrhea, chlamydia, syphilis, and HIV testing rates and chlamydia and gonorrhea prevalence.MethodsFrom the de-identified commercial claims data of OptumLabs Data Warehouse, we identified men and women aged 15-60 years classified as having high-risk sexual relationships as diagnosis codes: Z72.51 for opposite-sex, Z72.52 for same-sex, and Z72.53 for same-and-opposite-sex relationships, stratified by gender, age group, region, type of health plan, and HIV status. We estimated STI testing rate and prevalence for chlamydia and gonorrhea among patients with high-risk sexual relationships. HIV testing was assessed only in high-risk sexual relationship patients without HIV.ResultsAmong 8.2 million females and 7.3 million males aged 15-60 years in the database from 2016 to 2019, 115,884 patients (0.7% of female, 0.8% of male) including 3,535 patients with HIV were diagnosed with high-risk sexual relationships. The testing rates for gonorrhea, chlamydia, syphilis, and HIV were 69.4% (confidence interval [CI]: 69.1-69.7), 68.9% (CI: 68.6-69.2), 43.4% (CI: 43.1-43.7), and 41.7% (CI: 41.4-42.0), respectively. Among patients with valid chlamydia and gonorrhea tests, 7.2% (CI: 7.0-7.5) and 2.6% (CI: 2.4-2.8) had positive chlamydia and gonorrhea test results, respectively, and varied by type of high-risk sexual relationship.ConclusionsOur study findings of suboptimal STI screening among patient in high-risk sexual relationships are consistent with previous studies. Administrative records confirmed by lab results indicate a need for STI counseling, testing, and treatment among patients who are diagnosed with high-risk sexual relationships with same-sex, opposite-sex, or same-and-opposite sex partners.     

Prevalence,incidence and recurrence of sexually transmitted infections in HIV-negative adult women in a rural South African setting

Objective

Sexually transmitted infections (STIs), including syphilis, chlamydia, gonorrhoea and trichomoniasis, are of global public health concern. While STI incidence rates in sub-Saharan Africa are high, longitudinal data on incidence and recurrence of STIs are scarce, particularly in rural areas. We determined the incidence rates of curable STIs in HIV-negative women during 96 weeks in a rural South African setting.

Methods

We prospectively followed participants enrolled in a randomised controlled trial to evaluate the safety and efficacy of a dapivirine-containing vaginal ring for HIV prevention in Limpopo province, South Africa. Participants were included if they were female, aged 18–45, sexually active, not pregnant and HIV-negative. Twelve-weekly laboratory STI testing was performed during 96 weeks of follow-up. Treatment was provided based on vaginal discharge by physical examination or after a laboratory-confirmed STI.

Results

A total of 119 women were included in the study. Prevalence of one or more STIs at baseline was 35.3%. Over 182 person-years at risk (PYAR), a total of 149 incident STIs were diagnosed in 75 (65.2%) women with incidence rates of 45.6 events/PYAR for chlamydia, 27.4 events/100 PYAR for gonorrhoea and 8.2 events/100 PYAR for trichomoniasis. Forty-four women developed ≥2 incident STIs. Risk factors for incident STI were in a relationship ≤3 years (adjusted hazard ratio [aHR]: 1.86; 95% confidece interval [CI]: 1.04–2.65) and having an STI at baseline (aHR: 1.66; 95% CI: 1.17–2.96). Sensitivity and specificity of vaginal discharge for laboratory-confirmed STI were 23.6% and 87.7%, respectively.

Conclusion

This study demonstrates high STI incidence in HIV-negative women in rural South Africa. Sensitivity of vaginal discharge was poor and STI recurrence rates were high, highlighting the shortcomings of syndromic management in the face of asymptomatic STIs in this setting.     

Sexually transmitted infections prevalence rates in slum communities of Dhaka, Bangladesh

The study objective was to estimate the prevalence of selected sexually transmitted infections (STIs) and associated factors among Dhaka slum dwellers. Blood and urine specimens were collected from 1534 men and women. Participants in this cross-sectional study responded to a questionnaire, providing socioeconomic data, symptomatology and treatment-seeking behaviour. Specimens were tested for syphilis, hepatitis B (HBsAg), Neisseria gonorrhoeae, Chlamydia trachomatis, and HIV. Serologic evidence of syphilis infection was found in 6.0% of respondents, HBsAg in 3.8%. Prevalence rates of gonorrhoea and chlamydia were 1.7% and <1%, respectively. No HIV infections were found. Men were more than twice as likely as women to be infected with syphilis or HBsAg carriers. Behaviours facilitating STI transmission were common among men. Syphilis infection is prevalent enough to warrant the initiation of screening programmes in this population. The prevalence rate of hepatitis B carriage suggests that this population would benefit from universal vaccination against hepatitis B.     

Diphtheria in the WHO European Region, 2010 to 2019

BackgroundDiphtheria is uncommon in the World Health Organization (WHO) European Region. Nevertheless, sporadic cases, sometimes fatal, continue to be reported.AimTo report on diphtheria cases and coverage with first and third doses of diphtheria, tetanus and pertussis vaccines (DTP1 and DTP3, respectively) for 2010–19 in the Region with a focus on 2019.MethodsData on diphtheria cases were obtained from WHO/United Nations International Children''s Emergency Fund (UNICEF) Joint Reporting Forms submitted annually by the Region’s Member States. WHO/UNICEF Estimates of National Immunization Coverage for DTP1 and DTP3 were summarised for 2010–19. For 2019, we analysed data on age, and vaccination status and present data by country on DTP1 and DTP3 coverage and the percentage of districts with ≥ 90% and < 80% DTP3 coverage.ResultsFor 2010–19, 451 diphtheria cases were reported in the Region. DTP1 and DTP3 coverage was 92–96% and 95–97%, respectively. For 2019, 52 cases were reported by 11 of 48 countries that submitted reports (including zero reporting). Thirty-nine countries submitted data on percentage of their districts with ≥ 90% and < 80% DTP3 coverage; 26 had ≥ 90% districts with ≥ 90% coverage while 11 had 1–40% districts with < 80% coverage.ConclusionLong-standing high DTP3 coverage at Regional level probably explains the relatively few diphtheria cases reported in the Region. Suboptimal surveillance systems and inadequate laboratory diagnostic capacity may also be contributing factors. Still, the observed cases are of concern. Attaining high DTP3 coverage in all districts and implementing recommended booster doses are necessary to control diphtheria and prevent outbreaks.     

Surveillance systems to monitor antimicrobial resistance in Neisseria gonorrhoeae: a global,systematic review, 1 January 2012 to 27 September 2020

BackgroundEffective surveillance of antimicrobial resistance (AMR) in Neisseria gonorrhoeae is required for the early detection of resistant strains and to ensure that treatment guidelines are appropriate for the setting in which they are implemented. AMR in N. gonorrhoeae has been identified as a global health threat.AimWe performed a systematic review to identify and describe surveillance systems targeting AMR in N. gonorrhoeae.MethodsWe searched Medline, PubMed, Global Health, EMBASE, CINAHL, Web of Science and ProQuest databases and grey literature between 1 January 2012 and 27 September 2020. Surveillance systems were defined as the continuous, systematic collection, analysis and interpretation of N. gonorrhoeae resistance data. The key components of surveillance systems were extracted, categorised, described and summarised.ResultsWe found 40 publications reporting on N. gonorrhoeae AMR surveillance systems in 27 countries and 10 multi-country or global surveillance reports. The proportion of countries with surveillance systems in each of the WHO''s six regions ranged from one of 22 countries in the Eastern Mediterranean and five of 54 in Africa, to three of 11 countries in South East Asia. Only four countries report systems which are both comprehensive and national. We found no evidence of a current surveillance system in at least 148 countries. Coverage, representativeness, volume, clinical specimen source, type and epidemiological information vary substantially and limit interpretability and comparability of surveillance data for public health action.ConclusionGlobally, surveillance for N. gonorrhoeae AMR is inadequate and leaves large populations vulnerable to a major public health threat.     

Current practices of partner notification among MSM with HIV, gonorrhoea and syphilis in the Netherlands: an urgent need for improvement

ABSTRACT: BACKGROUND: Partner notification (PN) among individuals newly diagnosed with HIV/STI is seen as a vital tool to identify others at risk of infection. However, hardly any data are available on the effectiveness of PN on HIV/STI transmission in the Netherlands. This study aims to fill this gap by assessing current PN practices, case-finding effectiveness, and determinants of being notified among men having sex with men (MSM) in the Netherlands. METHODS: Nurses from five STI centers participated in a prospective pilot study on PN outcomes (partners being: at risk, notifiable, notified, and tested) for HIV/STI, by completing a newly developed PN registration form (PN database). PN outcomes including case-finding effectiveness (number of newly diagnosed cases in partners/number of partners being tested) for HIV, syphilis, and gonorrhoea were studied among MSM. Furthermore, the national STI database was analyzed to identify determinants of being notified. The number of infections that remained undetected was estimated based on these two databases. RESULTS: In total 105 MSM, newly diagnosed with HIV/STI, reported 612 sexual partners at risk of whom 41% were notifiable and 31% were notified. Patient referral was the predominant PN method (90%). The overall case-finding percentage was 36% (HIV: 15-33%, gonorrhoea: 17- 50% and syphilis: 4-11%). Case-finding percentages were lower in the national STI database: 21% (5%, 28%, 12%). Persons with one or more sexual partners, known HIV positives, and IDU were more likely to be notified to the STI clinic. Notified clients were more likely to have HIV/STI than unnotified clients (OR 1.7-2.5). Based on these two databases, an estimated 75 to 133 infections remained undetected (HIV: 12-90; gonorrhoea: 28-97; syphilis: 5-12 infections). CONCLUSIONS: Partner notification among MSM in the Netherlands is suboptimal; an extensive number of STI/HIV infections remained undetected mainly due to unnotifiable partners. To enhance PN practices, combined and innovative PN interventions such as Internet-based PN will be implemented for hard-to-reach MSM and other risk groups.     

Community Empowerment Among Female Sex Workers is an Effective HIV Prevention Intervention: A Systematic Review of the Peer-Reviewed Evidence from Low- and Middle-Income Countries

We conducted a systematic review and meta-analysis of community empowerment interventions for HIV prevention among sex workers in low- and middle-income countries from 1990–2010. Two coders abstracted data using standardized forms. Of 6,664 citations screened, ten studies met inclusion criteria. For HIV infection, two observational studies showed a significantly protective combined effect [odds ratio (OR): 0.84, 95 % confidence interval (CI): 0.709–0.988]. For STI infection, one longitudinal study showed reduced gonorrhoea/chlamydia (OR: 0.51, 95 % CI: 0.26–0.99). Observational studies showed reduced gonorrhoea (OR: 0.65, 95 % CI: 0.47–0.90), but non-significant effects on chlamydia and syphilis. For condom use, one randomized controlled trial showed improvements with clients (ß: 0.3447, p = 0.002). One longitudinal study showed improvements with regular clients (OR: 1.9, 95 % CI: 1.1–3.3), but no change with new clients. Observational studies showed improvements with new clients (OR: 3.04, 95 % CI: 1.29–7.17), regular clients (OR: 2.20, 95 % CI: 1.41–3.42), and all clients (OR: 5.87, 95 % CI: 2.88–11.94), but not regular non-paying partners. Overall, community empowerment-based HIV prevention was associated with significant improvements across HIV outcomes and settings.
