Genetic characterisation of lymphogranuloma venereum in Spain: a multicentre study.

INTRODUCTION: Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by Chlamydia trachomatis genotypes L1-L3. A combination of techniques with high discriminatory capacity such as multilocus sequence typing (MLST) and the analysis of the ompA gene may be useful to determine the greater penetration of certain strains in transmission networks and their relationship with certain tropisms. AIM: The aim of this study was to investigate the molecular epidemiology of LGV isolates from different regions of Spain. METHODS: Genetic characterisation of LGV isolates detected in six hospitals from Spain between 2018 and 2019 was performed. MLST (five variable regions: hctB, CT058, CT144, CT172 and pbpB) and ompA sequence determination were used to study the LGV strains. RESULTS: Most of the 161 LGV isolates (93.8%) were detected in men who have sex with men (MSM). At least 43.5% of the patients presented with HIV coinfection and 53.4% were symptomatic, with proctitis being the most prevalent symptom (73.3%). Most isolates were detected in Barcelona (n=129).The distribution of ompA genovariants was as follows: 56.1% belonged to L2, 24.3% to L2b, 5.4% to L2bV1, 4.7% to L2bV4, 4.1% to L1, 2.7% to L2b/D-Da, 2.0% to L2bV2 and 0.7% to L2bV7. MLST was successfully performed in 81 samples and 9 different sequence types (STs) were detected. The ompA and MLST combination obtained 17 different genetic profiles, with L2-ST53 and L2-ST58 being the most prevalent (29.5% and 14.1%, respectively). L1 genotype strains belonged to ST23 (n=3) and ST2 (n=3). CONCLUSION: LGV infections were mainly found in MSM living with HIV and with proctitis. The joint analysis of ompA and MLST genetic characterisation techniques showed a high discriminatory capacity. Our findings suggest a cocirculation of L2 and L2b ompA genotypes, and with the inclusion of MLST characterisation, the most prevalent profiles were ompA genotype L2-MLST ST53 and L2-MLST ST58.

Drassanes Exprés: a public and confidential testing service for asymptomatic STIs with same-day result notification.

BACKGROUND: STIs are a major public health concern. Screening programmes for asymptomatic users are key components of STI control. Traditional limitations of screening programmes include low population coverage and delays in treatments, thus reducing the expected impact on STI control. In our centre, the normal time from test to results was 4 days, and 7 days until treatment was established.To reduce time to treatment and to increase population coverage, we developed 'Drassanes Exprés', a testing service for asymptomatic STIs. The objectives of this study were to provide a guide for the implementation of a service with these characteristics and to evaluate the results of this intervention. METHODS: The Drassanes Exprés programme was launched in Spain on 07 November 2016 as a public, confidential and free-of-charge testing service for asymptomatic STIs, with same-day result notification. For this walk-in service, confidentiality was obtained by registering all information into the Laboratory Internal Software instead of the Electronic Patient Records. Samples were processed in a point-of-care laboratory and result notification was provided via mail or short message service.Information about workflow, screening protocols and result interpretation is detailed. Additionally, demographic characteristics, STI prevalence, and time from patients' sample collection to notification and treatment are analysed. RESULTS: Between 07 November 2016 and 07 November 2019, 13 993 users attended the Drassanes Exprés screening programme. Of these, 0.5% were transgender people, 29.3% women, 45.2% men who have sex with men and 25.1% men who have sex with women. The median age was 31 years (range: 26-39 years). Overall, 14.6% of users tested positive for at least one STI. The most prevalent infection was Chlamydia trachomatis (8.3%), followed by Neisseria gonorrhoeae (5.7%), syphilis (1.8%), HIV (0.4%) and hepatitis C virus (0.2%). The median time from test to results was 2.4 hours (range: 2-3.1 hours). Of 2049 users diagnosed with an STI, treatment was achieved in 97.0% of cases; the average time to treatment was 2.0 days. CONCLUSIONS: Drassanes Exprés is the first public programme for rapid, asymptomatic, STI screening and treatment in Spain. Assessing high-risk practices and providing confidentiality, easy access and rapid results/treatments are key elements in the development of STI screening programmes.

Neisseria gonorrhoeae antimicrobial resistance in Spain: a prospective multicentre study.

OBJECTIVES: Gonococcal infection is one of the most reported sexually transmitted infections and antimicrobial resistance in Neisseria gonorrhoeae (NG) is challenging for the treatment of this infection. This observational study aimed to describe antimicrobial resistance of NG and epidemiological data from patients with gonococcal infection in eight regions of Spain, for updating the local therapeutic guidelines. METHODS: MICs of penicillin, cefixime, ceftriaxone, azithromycin, ciprofloxacin, fosfomycin and gentamicin were determined by Etest for all NG isolates recovered from 1 April 2018 to 30 September 2019 from 10 hospitals in Spain. Resistance determinants were identified using logistic regression analysis. Differences with a P value <0.05 were considered statistically significant. RESULTS: Antimicrobial susceptibility testing was performed for 2571 gonococci isolated from 2429 patients. 44.5% (945/2124) of patients were MSM. The resistance rate to extended-spectrum cephalosporins was low, with 0.2% (6/2561) of isolates resistant to ceftriaxone and 1.7% (44/2517) of isolates resistant to cefixime. The overall azithromycin resistance rate was 12.1% (310/2560), but differed greatly depending on the area. 56.2% (1366/2429) of the strains studied were ciprofloxacin resistant. MIC50 and MIC90 values of gentamicin and fosfomycin were 4 and 8 mg/L and 24 and 48 mg/L, respectively. CONCLUSIONS: Our study shows that NG susceptibility to extended-spectrum cephalosporins remains high in Spain. The azithromycin resistance rate questions the suitability of dual therapy. This study provides data of interest for updating the national treatment guidelines and highlights the need to develop and implement a national sentinel gonococcal antimicrobial susceptibility programme.

Screening for asymptomatic STIs in HIV-infected men who have sex with men.

We aimed to study the prevalence, characteristics and risk factors of asymptomatic sexually transmitted infections (STIs) in HIV-infected men who have sex with men (MSM). We conducted a prospective cross-sectional study, including asymptomatic HIV-infected MSM attending regular visits between December 2014 and December 2017. Of the 301 patients included, 60 patients (19.9%) presented at least one STI. The most common STI was syphilis (33 of 69 STIs), followed by chlamydia (19 of 69), gonorrhoea (10 of 69), hepatitis C virus (4 of 69) and lymphogranuloma venereum (3 of 69). Illicit drug use during sex was the only variable significantly associated with the presence of an STI on multivariate analysis (OR 2.13; 95% CI 1.17-3.89). We were unable to identify a subgroup of patients where we could potentially avoid STI screening. Our findings support current guidelines that recommend routine screening for all HIV-infected MSM regardless of their self-reported sexual history.

Single-Locus-Sequence-Based Typing of the mgpB Gene Reveals Transmission Dynamics in Mycoplasma genitalium.

Sexually transmitted infections (STIs) by Mycoplasma genitalium are a major problem worldwide, especially given their marked and rapid propensity for developing antimicrobial resistance. Since very few treatment options exist, clinicians face an important challenge in the management of the infection. In this scenario, little is known regarding the transmission dynamics of M. genitalium and the epidemiology of antimicrobial resistance. This mgpB-based molecular typing study, conducted among 54 asymptomatically infected individuals prospectively recruited from an STI screening service, reveals two distinct epidemiological clusters that significantly correlate with sexual conduct in heterosexuals and men who have sex with men (MSM), respectively. This well-defined structuration suggests the presence of two independent sexual networks with little connectivity between them. On the other hand, the study demonstrates the multiclonal feature of the emergence of antibiotic resistance in M. genitalium to both macrolides and fluoroquinolones. The high prevalence of macrolide resistance in M. genitalium among MSM, influenced by dense network connectivity and strong antibiotic selective pressure, may correspond to allodemics affecting other STIs such as gonorrhea, syphilis and enteric pathogens. Collaterally, the structural and functional impact of mutations in the mgpB gene, encoding the major adhesin P140 (MgpB), may require further investigation.

Prevalence of Mycoplasma genitalium and macrolide resistance among asymptomatic people visiting a point of care service for rapid STI screening: a cross-sectional study.

OBJECTIVES: Although rapid screening and treatment programmes have been recently implemented to tackle STIs, testing Mycoplasma genitalium (MG) among asymptomatic populations is not currently recommended due to the lack of scientific evidence and the emergence of antibiotic resistance. The main objective of this study was to estimate the prevalence of MG and macrolide resistance among asymptomatic people visiting a point of care service for rapid STI screening and to identify risk factors associated with the acquisition of this infection. METHODS: Between October 2017 and January 2018, a total of 890 asymptomatic individuals attending to the STI screening service Drassanes Exprés in Barcelona, Spain, were tested for MG and macrolide resistance using the molecular ResistancePlus MG assay (SpeeDx, Australia). Asymptomatically infected individuals were invited to attend the STI Unit for resistance-guided antimicrobial therapy. RESULTS: Overall, the prevalence of MG was 7.4% (66/890; 95% CI 5.8% to 9.3%), being higher among men who have sex with men (MSM) (46/489) compared with heterosexual men and women (20/401; p=0.012). Macrolide resistance was found in 32/46 (69.6%; 95% CI 54.2% to 82.3%) MSM, while only 2/20 (10.0%; 95% CI 1.2% to 31.7%) infections among heterosexuals presented macrolide resistance-mediated mutations (p<0.001). MSM behaviour, receptive anal intercourse, HIV positive status, syphilis history and high-risk sexual activity (more than five sexual partners in the last 3 months) were significantly associated with MG infection. Furthermore, the resistance-guided therapy approach was implemented in 36/66 (54.6%) individuals. CONCLUSIONS: The research provides further data regarding the prevalence of MG and macrolide resistance among asymptomatic individuals. It also identifies higher risk subpopulations which might be targets for MG screening. Nevertheless, there is insufficient data to justify MG testing among asymptomatic individuals and current STI guidelines should be followed until evidence shows the cost and effectiveness of screening.

Antimicrobial susceptibility of Neisseria gonorrhoeae in Barcelona during a five-year period, 2013 to 2017.

IntroductionIncreasing rates of antimicrobial resistance in Neisseria gonorrhoeae cause problems for treating gonorrhoea.AimThis observational study aimed to describe isolates from all patients found infected with N. gonorrhoeae, in Barcelona, Spain, between 2013 and 2017, and with available antimicrobial susceptibility data.MethodsMinimum inhibitory concentrations (MICs) of penicillin (PEN), cefixime (CFM), ceftriaxone (CRO), azithromycin (AZM), ciprofloxacin (CIP), spectinomycin (SPT), fosfomycin (FOF) and gentamicin (GEN) were determined by E-test. Susceptibility was assessed using clinical breakpoints from the European Committee on Antimicrobial Susceptibility Testing. Time trends for PEN, CFM, AZM and CIP were investigated using logistic regression.ResultsOf 1,979 patients with infection (2,036 isolates), 1,888 (95.4%) were men. Patient median age was 32 years. The proportions of isolates resistant to extended-spectrum cephalosporins were low, with 0.3% (5/1,982) resistant to CRO and 4.9% (98/1,985) to CFM. AZM resistance prevalence was 2.7% (52/1,981), including 16 isolates detected in 2016 and 2017, with high-level resistance. For CIP, 51.3% (1,018/1,986) of isolates were resistant, and for PEN, 20.1% (399/1,985). All isolates were susceptible to SPT. MIC50 and MIC90 values of GEN were 4 and 6 mg/L and of FOF 12 and 24 mg/L, respectively. Between 2013 and 2017, PEN and CFM resistance rates each decreased from 28.1% (92/327) to 12.2% (70/572) and from 8.3% (27/327) to 4.4% (25/572) (p ≤ 0.0073). In contrast, AZM resistance prevalence appeared to increase from 1.5% in 2014 (5/340) to 3.0% (17/572) in 2017. No trend was identified for CIP.ConclusionAntimicrobial susceptibility surveillance is important to timely detect new phenotypes and trends.

Multicenter Clinical Evaluation of a Novel Multiplex Real-Time PCR (qPCR) Assay for Detection of Fluoroquinolone Resistance in Mycoplasma genitalium.

Mycoplasma genitalium causes a common sexually transmitted infection with a marked propensity to develop antimicrobial resistance. As few treatment options exist, this poses significant challenges to clinicians. Recent diagnostic advances have resulted in tests that report the simultaneous detection of M. genitalium and any resistance to macrolides, the first-line treatment. This allows for therapy to be tailored to the individual, thereby optimizing treatment outcomes. However, resistance to fluoroquinolones, the second-line treatment, is increasing in M. genitalium In this study, we describe a new assay, MG+parC (beta), which simultaneously reports the detection of M. genitalium and five parC mutations that have been associated with resistance to fluoroquinolones. These mutations affect the amino acid sequence of ParC at residues S83R (A247C), S83I (G248T), D87N (G259A), D87Y (G259T), and D87H (G259C). The study tested the MG+parC (beta) assay with 202 M. genitalium-positive clinical samples from Australia (n = 141) and Spain (n = 61). Compared to Sanger sequencing, the assay performed with a kappa value of 0.985 (95% confidence interval [CI], 0.955 to 1.000), with a mutation detection sensitivity of 97.6% (95% CI, 87.4 to 99.9), and specificity of 100.0% (95% CI, 97.7 to 100.0). Fluoroquinolone resistance-associated mutations in parC targeted by the assay were more prevalent among the Australian cohort (23.4% [95% CI,16.3 to 31.8]) compared to the Spanish population (8.8% [95% CI, 2.9% to 19.3%]) (P = 0.019). The MG+parC (beta) kit is a simple and reliable method for simultaneous detection of M. genitalium and fluoroquinolone resistance-associated mutations in clinical settings. This novel diagnostic tool may extend the utility of the second line of antimicrobial therapies in M. genitalium infection.

A novel tp0548 sequence-type of Treponema pallidum has been identified in a genital ulcer sample collected from a patient diagnosed with primary syphilis at the Hospital Universitari Vall d'Hebron in Barcelona. Following the nomenclature used in the Enhanced Centers for Disease Control and Prevention Typing methodology, letter "z" has been assigned to the new sequence type.

[Neisseria gonorrhoeae: antimicrobial resistance and study of population dynamics. Situation in Barcelona in 2011]. / Neisseria gonorrhoeae: resistencias antimicrobianas y estudio de la dinámica poblacional. Situación en 2011 en Barcelona.

BACKGROUND: Due to the high rates of antimicrobial resistance to certain antibiotics, together with the emergence of Neisseria gonorrhoeae (NG) with reduced susceptibility and resistance to third-generation cephalosporins, gonococcal infection is becoming a public health problem. The objectives of the study were: To keep track of the antimicrobial susceptibility of NG strains obtained from January to August 2011. To study the population dynamics. METHODS: The antimicrobial susceptibility was studied by disk-diffusion and E-test. The genotyping was performed by NG-MAST method. RESULTS: Of a total of 100strains studied, 59% showed intermediate sensitivity to penicillin and 9% were resistant. According to EUCAST, we detected 3gonococci with reduced susceptibility to ceftriaxone, 10 to cefixime and one with high-level resistance to both antibiotics (MIC 1.5µg/ml). MIC50 and MIC90 to cefixime were 0.016 and 0.125µg/ml, respectively, whereas to ceftriaxone they were <0.016 and 0.064µg/ml, respectively. Almost all (99%) of the strains were resistant to doxycycline, 53% to ciprofloxacin, 3% to azithromycin, and 1% to spectinomycin. The most prevalent ST was ST1407, predominantly associated to resistance or reduced sensitivity to cephalosporins or macrolides. CONCLUSIONS: NG has developed significant rates of resistance to various antibiotics. One strain has been detected with high level resistance to third generation cephalosporins, and several strains with reduced susceptibility. An increase in MIC50 and MIC90 to these antibiotics has also been observed. NG population structure remains stable and common to the rest of Europe, although two new ST (ST7226 and ST7227) have been identified that could be selected and acquire high levels of resistance to cephalosporins.

Methicillin-resistant and methicillin-sensitive Staphylococcus aureus in pork industry workers, Catalonia, Spain.

Background: Methicillin-resistant S. aureus (MRSA) especially ST398, is a zoonotic agent. This study aimed to determine the prevalence of methicillin-susceptible S. aureus (MSSA) and MRSA among workers in the pork production chain. Methods: 659 workers associated with 123 pig farms, livestock transporters, one pig slaughterhouse, pork transporters and 23 pork butcheries were studied for S. aureus recovery, and all isolates were characterized (antibiotic resistance, MLST and spa-typing). Results: The prevalence of S. aureus was 35.5%, 75.6% of isolates being MRSA. The prevalence of MRSA was 68.7% (149/217) among pig farm, 33.9% (19/56) livestock transporters, 2.9% (9/306) slaughterhouse, 0% in pork transporters (0/36) and butchery workers (0/44). Of the 234 S. aureus-positive workers, 100% (149/149) of pig farm workers, 82.6% (19/23) of livestock transporters, and 16.4% (9/55) of slaughterhouse workers carried MRSA isolates (p < 0.001). Of the workers who had contact with live swine, 61.8% (178/288) were S. aureus-positive, MRSA being detected in 96.1% of cases (p < 0.001). The most frequent lineage among MRSA were: ST398 (97.7%; 173/177) and ST1 (1.7%; 3/177); and among MSSA were ST30 (19.2%; 11/57) and ST5 (10.5%; 6/57). The most frequent spa-types among MRSA were t011 (93.8%, 166/177) and t1451 (2.25%, 4/177), and among MSSA: t084 (10.5%, 6/57) and t021 (7.0%, 4/57). All MRSA isolates showed resistance to tetracycline, 92.7% to clindamycin, 81.9% to erythromycin and 40.1% to cotrimoxazole. Conclusions: Pig industry workers having occupational contact with live animals present a high risk of colonization of MRSA, especially by MRSA-ST398. Prevention measures should be intensified in any employment sector involving live animals.

Risk Factors for Relapse in Acute Bacterial Prostatitis: the Impact of Antibiotic Regimens.

The aim of the study was to analyze the risk factors for relapse in patients with acute bacterial prostatitis (ABP), focusing on the impact of different antibiotic regimens. We conducted an observational study of all patients diagnosed with ABP (irritative and/or obstructive urinary symptoms, temperature of >37.8°C, and the presence of bacteriuria in urine culture, in the absence of data suggesting pyelonephritis) from January 2017 to December 2018. The main outcome was relapse. We performed a multivariate analysis to identify the risk factors associated with relapse. A propensity score with inverse weighting was applied to attenuate antibiotic selection bias. We included 410 patients. The mean age was 68 years; 28.8% had diabetes mellitus, and 61.1% benign prostatic hyperplasia. The most common isolated bacteria were Escherichia coli (62.4%) and Klebsiella spp. (10%). The overall resistance rate was 39.5% to quinolones. The mortality rate was 1.2%, and the relapse rate was 6.3%. The only independent risk factor for relapse was inadequate antibiotic therapy (odds ratio [OR] 12.3; 95% confidence interval [95% CI], 3.5 to 43.1). When the antibiotic was modified according to the susceptibility pattern, the rates of relapse were 1.8% in those treated with ciprofloxacin, 3.6% with intravenous beta-lactam, 9.3% with co-trimoxazole, and 9.8% with oral (p.o.) beta-lactam (P = 0.03). Treatment with oral beta-lactam (OR, 5.3; 95% CI, 1.2 to 23.3) and co-trimoxazole (OR, 4.9; 95% CI, 1.1 to 23.2) were associated with a risk of relapse. In this large real-life observational study, a significantly higher relapse rate was observed when antibiotic treatment was inadequate. When the antibiotic was tailored, quinolones and intravenous beta-lactams had a lower relapse rate than co-trimoxazole and oral beta-lactams. IMPORTANCE In the manuscript, we report a large series of acute bacterial prostatitis cases and describe data about the etiology, antibiotic resistance rate, and outcome, specially focused on the risk factors for relapse. We found high rates of resistance to the most frequently used antibiotics and a high relapse rate in patients whose treatment was not adjusted according to their microbiological susceptibility. We did not observe differences, though, in mortality or relapse according to appropriate or inappropriate empirical treatment. What is new in this article is the different relapse rates observed depending upon the definitive adequate antibiotic used. Quinolones and intravenous (i.v.) beta-lactam have lower rates of relapse (1.8% and 3.6%, respectively) compared to co-trimoxazole and oral (p.o.) beta-lactam (3.3% and 9.8%, respectively). Clinicians should carefully choose an adequate antibiotic for definitive ABP treatment depending on the results of microbiological isolation, using quinolones as the first option. Whenever quinolones cannot be administered, i.v. beta-lactams seem to be the second-best option.

Survey of diagnostic resources for STI in Spain.

BACKGROUND: Scarce information is available on the resources to deal with the Sexually Transmitted Infections (STIs), both in the clinic and in the laboratory. The objective is to describe and know the reality of the clinics and laboratories that treat these infections in Spain. METHODS: Cross-sectional observational study with data collection through a survey aimed at the members of the GEITS Group. RESULTS: Responses were obtained from 24 centers (response rate 38.1%) belonging to 10 Autonomous Communities. Regarding STI consultations, 38% require that the patient present a health card to provide assistance, and 31.8% only provide it by referral from another doctor. The 52.4% perform diagnostic methods in the care center. Regarding laboratories, 18.2% do not offer immediate response diagnostic tests, although 100% have PCR against Neisseria gonorrhoeae and Chlamydia trachomatis, 47.8% against Mycoplasma genitalium and 65% detect lymphogranuloma venereum genotypes. All laboratories continue to perform culture and gonococcal sensitivity techniques, and 20% perform molecular methods for detection of MG antimicrobial resistance. CONCLUSION: There is great variability in the provision of human and material resources both in the clinics and in the laboratories that attend STIs. In a significant number of centers there are limitations for patient access. Although laboratories have molecular biology technologies, not all of them offer immediate response tests. All laboratories detect N. gonorrhoeae infection by PCR and also by culture, which allows sensitivity testing in all centers.

Multilocus sequence typing of Treponema pallidum subsp. pallidum in Barcelona.

Aim: To implement the multilocus sequence typing (MLST) methodology in syphilis samples previously characterized by enhanced CDC typing (ECDCT) and macrolide resistance. Materials & methods: MLST was performed on genital ulcer and blood samples by analyzing a region of the tp0136, tp0548 and tp0705loci using Sanger sequencing. Results: Up to 59/85 (69.4%) of genital ulcer and 4/39 (10.3%) of whole blood samples were fully typed. The most frequent profiles were 1.3.1 (56%) and 1.1.1 (11%). All the 1.3.1 samples typed carried the A2058G mutation, responsible for macrolide resistance. MLST and ECDCT showed similar overall typing yields. Conclusion: Several allelic profiles of T. pallidum subsp. pallidum were identified and classified into two major genetic clades in Barcelona. Our results were similar to that described in Europe.

Circulation of multi-drug-resistant Shigella sonnei and Shigella flexneri among men who have sex with men in Barcelona, Spain, 2015-2019.

BACKGROUND: In high-income countries, shigellosis is mainly found in travellers to high-risk regions or in men who have sex with men (MSM). This study investigated the genomic characteristics and the features of antimicrobial resistance of MSM-associated Shigella flexneri and Shigella sonnei circulating in Barcelona, Spain, elucidating their connectivity with contemporaneous Shigella spp. from other countries. METHODS: Antimicrobial susceptibility, whole-genome sequencing, genomic characterization and phylogenetic analysis were performed in MSM-associated Shigella spp. recovered from 2015 to 2019. Reference genomes of MSM-associated Shigella spp. were included for contextualization and to determine their connection with international outbreaks. RESULTS: In total, 44 S. flexneri and 26 S. sonnei were identified among MSM. Overall, 80% showed resistance to azithromycin, 65.7% showed resistance to trimethoprim-sulphamethoxazole and 32.8% showed resistance to ciprofloxacin; 27.1% were resistant to all three antimicrobials. mphA and/or ermB, and qnrS and mutations in the quinolone resistance determining regions were found in the azithromycin- and ciprofloxacin-resistant isolates, respectively. Additionally, two isolates carried blaCTX-M-27. Single-nucleotide-polymorphism-based analysis revealed that the isolates were organized into different lineages, most of which were closely related to dominant MSM-associated lineages described previously in the UK and Australia. CONCLUSIONS: This study investigated the circulation of lineages of S. flexneri and S. sonnei among MSM in Spain that were mainly resistant to first-/second-line oral treatments, and closely related to dominant MSM-associated lineages described previously in the UK and Australia. These data reinforce the urgent need for the implementation of public health measures focusing on the early detection and prevention of transmission of this emerging pathogen, which is contributing to the antimicrobial resistance crisis in sexually transmitted infections.
