Abstract
BACKGROUND The indiscriminate use of antibiotics has accelerated antimicrobial resistance (AMR) in Neisseria gonorrhoeae (NG), emphasising the need to follow treatment guidelines. This study aimed to assess the rate of adherence to standard treatment among patients with gonorrhoea and identify influencing factors. METHODS A survey was conducted in Guangdong province, China, involving uncomplicated gonorrhoea cases registered in the Chinese Information System for Disease Control and Prevention. Data on demographic characteristics and medical information were collected to determine the standard treatment rate, defined as the proportion of patients receiving treatment according to national guidelines (ie, a single dose of ceftriaxone 250 mg, spectinomycin 2 g, cefotaxime 1 g or other third-generation cephalosporins). Medication choices were documented. χ² tests and multilevel logistic regression were used to analyse factors associated with standard treatment. RESULTS The survey included 2424 patients with gonorrhoea from 59 hospitals. The standard treatment rate was 30.7% (743/2424), with 36.2% for females and 29.6% for males. Common reasons for substandard treatment included the use of non-guideline medications (42.3%, 710/1681) and incorrect dosing (36.2%, 605/1681). Factors associated with the standard treatment rate included gender, address, educational level, department, physicians' training, number of diagnosed gonorrhoea cases and hospital level. CONCLUSION The standard treatment rate for gonorrhoea in Guangdong province, China, is below expectations. Comprehensive measures, such as establishing a goal-directed monitoring system and implementing promotional activities, are needed to improve adherence to treatment guidelines.

Abstract
BACKGROUND Chlamydia trachomatis (CT) infection could lead to seriously adverse outcomes if left untreated. This study aimed to determine CT-related knowledge, opinion to testing, and practices of providers among different sexually transmitted infections (STI) related departments in hospitals in Shenzhen city, China, and also to explore the differences in these responses. MATERIALS AND METHODS From 1st April 2018 to 15th April 2018, a cross-sectional study was conducted in Shenzhen and 64 of 66 hospitals agreed to participate in this study. In the hospital sites, all the providers from the department of obstetrics and gynecology, department of dermatology and venereology, department of urology, and anorectal surgical department were recruited. A structured paper-based questionnaire was used to obtain data on CT-related information. RESULTS A total of 355 providers from 64 hospitals participated in the current study. Compared to providers from the department of dermatology and venereology, those from the department of obstetrics and gynecology (OR = 0.31, 95% CI 0.16-0.62), department of urology (OR = 0.32, 95% CI 0.16-0.65), and anorectal surgical department (OR = 0.25, 95% CI 0.09-0.71) were less likely to identify that "Be in a long-term mutually monogamous relationship with a partner who has been tested and has negative STI test results." is an appropriate way for a sexually active person to reduce risk of getting CT. Also, those from the department of obstetrics and gynecology (OR = 0.45, 95% CI 0.23-0.87) were less likely to identify that "Use latex condoms the right way every time you have sex" is another appropriate way. A high proportion of providers agreed that all sexually active patients attending to their department should be screened regularly (77.1%), and they are willing to offer opportunistic CT screening (96.0%). Only 11.4% of respondents correctly identified that the appropriate time frame of the CT retesting is three months. CONCLUSIONS Providers among STI-related departments in hospitals showed a very high willingness to offer opportunistic CT screening. However, this study showed important gaps in providers' knowledge and practices in China, targeted training in CT-related knowledge and practice is urgently needed.

Abstract
OBJECTIVES Ceftriaxone is currently the last-remaining empirical antimicrobial therapy for treatment of gonorrhoea. However, the high-level ceftriaxone-resistant gonococcal FC428 clone has shown transmission in China in recent years. Therefore, the aim of this study was to analyse ceftriaxone resistance among a collection of recent clinical isolates, with a specific focus on prevalence of the FC428 clone. METHODS A total of 70 consecutive gonococcal isolates were collected between May and October 2019 from a single hospital in Hangzhou, China, and analysed for antimicrobial susceptibility by the agar dilution method. STs were determined by PCR and sequences and isolates related to the FC428 clone were further characterized by WGS and phylogenetic analysis. RESULTS Ceftriaxone resistance (MIC >0.125 mg/L) was observed in 21 (30%) isolates, while 14 (20%) isolates displayed a ceftriaxone MIC of 0.125 mg/L. Importantly, seven (10%) isolates were related to the gonococcal FC428 clone based on the presence of mosaic penA allele 60.001, displaying identical or closely related STs, and phylogenetic analysis after WGS. These seven isolates displayed high-level ceftriaxone resistance (MIC = 1 mg/L) and all associated gonorrhoea cases resulted in treatment failure because oral cephalosporins were initially prescribed. Subsequent re-treatment with a higher dose (2 g) of IV ceftriaxone appeared to be successful because all patients returning for test-of-cure became culture-negative. CONCLUSIONS Here, we report a high percentage of the internationally spreading gonococcal FC428 clone among clinical isolates from a single hospital in Hangzhou, China. A high dose of ceftriaxone is currently the only recommended and effective therapy.

Abstract
Prevalence of co-infecting sexually transmitted infections (STIs) among patients newly diagnosed with anogenital warts is under-reported. Our objective is to determine the prevalence of six common STIs, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), genital herpes (herpes simplex virus type 2 [HSV-2]), HIV, and syphilis for patients visiting a sexual health clinic in Guangzhou, China. Demographics, sexual health, and medical histories were collected at patient intake. Patients diagnosed with anogenital warts (N = 200) were invited to participate. We collected urine samples, and urethral, cervical, and rectal swabs to test for CT, NG, and MG, and blood samples for serological detection of HSV-2, syphilis, and HIV. Overall 49 (24.5%) had a co-infection (22.2% of men and 27.7% of women). All six STIs were observed among men: CT (6.8%), NG (3.4%), MG (5.1%), HIV (4.3%), HSV-2 (4.3%), and syphilis (1.7%). Women had fewer STIs, but at higher rates: CT (13.3%), MG (6.0%), and HSV-2 (8.4%). Individual men had up to two co-infections, while women had no more than one co-infection. Chlamydia was the most common STI. Patients aged 18-25 years (35.4%) had the highest prevalence. Although opportunistic screening is often applied for high-risk groups, expansion to patients with anogenital warts in all health-care settings would improve detection of problematic asymptomatic co-infections, thereby increasing China's capacity to contribute toward global surveillance systems.

Abstract
INTRODUCTION Inappropriate use of antibiotics to treat gonorrhoea can lead to antibiotic resistance. Education programmes may be helpful for improving physician prescribing behaviours in accordance with treatment guidelines. As traditional education based on printed materials may have limited effect on guideline-based treatment, innovative education strategies are needed. The current trial aims to assess the effectiveness of a novel education intervention to increase guideline-based treatment of gonorrhoea in China. METHODS AND ANALYSIS We will conduct a two-arm cluster randomised control trial at 144 hospitals (clusters) in eight Chinese provinces. The intervention will include an online training video developed on the WenJuanXing platform that covers workflows and requirements for managing a patient with uncomplicated gonorrhoea. Outpatient physicians in dermatology (dermatovenerology), urology, andrology and gynaecology will be given access to the video via a quick response code. In hospitals allocated to the control arm, physicians will continue to participate in their standard of care training programme. The primary outcome is the proportion of gonorrhoea antibiotic prescriptions adherent to Chinese national guidelines at the cluster level. In addition, to understand the reasons of physician's non-adherence to the intervention by conducting a questionnaire survey will be considered as the secondary outcome of the study. ETHICS AND DISSEMINATION Ethical approval was obtained from the Medical Ethics Committee of the Chinese Academy of Medical Sciences Institute of Dermatology (2020-LS-004). All physicians will provide an informed consent prior to participating in the study. Findings of the trial will be disseminated through conferences and peer-reviewed journals, and will be used to develop training programmes for physicians. TRIAL REGISTRATION NUMBER ChiCTR2000029591.

Abstract
Introduction Antimicrobial resistance (AMR) of Neisseria gonorrhoeae (N. gonorrhoeae) becomes a grave public health problem in the world. A strengthened Antimicrobial Resistance Surveillance Program is needed to track the trend of AMR development. However, the lack of a proper antimicrobial susceptibility test (AST) method is a barrier to expand the AMR surveillance in China. Traditional agar dilution (AD) method is laborious and E-test strips have no approval license for clinical use. Herein, a Chinese group modified the microdilution (MD) method for clinical ASTs. The objective of this study is to compare the MD method with the AD method for N. gonorrhoeae AST. Materials and Methods A total of 166 clinical isolates were tested for antimicrobial susceptibility of ceftriaxone, spectinomycin, azithromycin, ciprofloxacin, tetracycline, and penicillin using MD and AD method simultaneously. Results of MD method were read manually or automatically. Rates of essential agreement (EA), category agreement (CA), minor error, and very major error were compared. Results The total EAs (compared with results read manually) of penicillin, tetracycline, ciprofloxacin, spectinomycin, ceftriaxone, and azithromycin were 90.4%, 97.0%, 85.5%, 100.0%, 94%, and 72.3%; and CAs were 82.5%, 94.0%, 100%, 100%, 95.2%, and 94%, respectively. Conclusion We conclude that the MD method might be an alternative for clinical AST of N. gonorrhoeae in China. In particular, MD method has the potency of accurate differentiation of isolates resistant to ceftriaxone or azithromycin, which were empirically recommended for gonococcal treatment, but its quality remained suboptimal, and further improvement is needed for clinical use.

Abstract
The sexually transmitted infection gonorrhea, caused by the Gram-negative bacterium Neisseria gonorrhoeae, can cause urethritis, cervicitis, and systemic disease, among other manifestations. N. gonorrhoeae has rapidly rising incidence along with increasing levels of antibiotic resistance to a broad range of drugs including first-line treatments. The rise in resistance has led to fears of untreatable gonorrhea causing substantial disease globally. In this review, we will describe multiple approaches being undertaken to slow and control this spread of resistance. First, a number of old drugs have been repurposed and new drugs are being developed with activity against Neisseria gonorrhoeae. Second, vaccine development, long an important goal, is advancing. Third, new diagnostics promise rapid detection of antibiotic resistance and a shift from empiric to tailored treatment. The deployment of these new tools for addressing the challenge of antibiotic resistance will require careful consideration to provide optimal care for all patients while extending the lifespan of treatment regimens.

Abstract
Gonococcal antimicrobial resistance (AMR) has become a global threat significantly hampering the control of gonorrhea. Many socioeconomic, biological, behavioral, and programmatic factors have played an important role in driving the emergence, transmission and spread of gonococcal AMR. However, research to address these scientific and programmatic questions is limited in China. Here we propose a ROADMAP (acronym for resistance surveillance, outcomes due to AMR, antibiotic stewardship and application, diagnostic tools, mechanisms of AMR, antimicrobial assessment, and population pharmacokinetics and pharmacodynamics) plan for expanding interdisciplinary collaborations to address the research needs in China.

Abstract
We report a recent (2018) gonorrhoeal urethritis caused by a multidrug-resistant Neisseria gonorrhoeae strain in China. The isolated N. gonorrhoeae strain from a male and female pair expressed high-level resistance to spectinomycin (SPC), azithromycin, and other antibiotics but was sensitive to ceftriaxone. The SPC high-level resistance (MIC = 2048 mg/L) was due to a small deletion in rspE that caused two amino acid changes in ribosomal protein S5.

Abstract
Purpose Gentamicin is a promising antimicrobial for the treatment of gonorrhea. The study aimed to evaluate gentamicin minimum inhibitory concentrations (MICs) of Neisseria gonorrhoeae isolates in China. Methods In this study, the agar dilution method was used to determine the MICs of 470 isolates collected in 2016 to four effective antimicrobials (gentamicin, azithromycin, ceftriaxone, and spectinomycin). Results Gentamicin MICs ranged from 1 to 8 mg/L. No isolate was resistant to gentamicin. Of seven isolates simultaneously resistant to azithromycin and ceftriaxone, 6 isolates demonstrated MICs of 4 mg/L or less to gentamicin. No cross relationships were found between MICs of gentamicinand susceptibility profiles of azithromycin, ceftriaxone, and spectinomycin. Conclusion The in vitro results suggest that gentamicin can be a promising treatment option for gonococcal infections in China. Clinical trials to evaluate the therapeutic efficacy of gentamicin are required.
