Gardnerella vaginalis in urinary tract infections, are men spared?

Gardnerella vaginalis in association with anaerobes has been linked to bacterial vaginosis in women, while urinary tract infections (UTIs) in men have rarely been reported. The aim of the review was to reveal the significance of G. vaginalis UTIs in men. Prevalence of G. vaginalis UTIs in men varied from 0.5 to >27% according to patients' groups. Most patients had comorbidity such as urolithiasis or stents, transplants, tumors and diabetes, however, infections can also affect immunocompetent patients. We observed G. vaginalis-associated bacteriuria and leukocyturia in a kidney transplant man. Complications of the UTIs such as bacteremia (in 9/11 cases), hydronephrosis (4/11) and abscesses or septic emboli have been reported. Bacterial vaginosis in female partners has been a risk factor for UTIs in males. In women, biofilm Gardnerella phenotype, stabilized by Atopobium vaginae and Prevotella bivia was linked to ≥6-fold higher antibiotic resistance rates compared with the planktonic phenotype. Non-susceptibility to metronidazole and levofloxacin was found also in males. Therefore, if aerobic urine cultures are negative, urine and blood samples from male patients with predisposing factors and clinical signs of UTIs and bacteremia, can be taken. Plates should be incubated for 2-4 days in capnophilic/microaerophilic conditions, however only anaerobic incubation can help with detecting G. vaginalis strains which grow only anaerobically. Susceptibility testing of the isolates is highly important. Briefly, adherent G. vaginalis phenotype can be sexually transmissible. Despite the infrequency of G. vaginalis UTIs in men, the infections should be considered since they are often linked to severe complications.

Changes in the prevalence of self-reported sexually transmitted bacterial infections from 2010 and 2017 in two large European samples of men having sex with men-is it time to re-evaluate STI-screening as a control strategy?

BACKGROUND/OBJECTIVES: Many European countries reported increased numbers of syphilis, gonorrhoea and chlamydia diagnoses among men who have sex with men (MSM) in recent years. Behaviour changes and increased testing are thought to drive these increases. METHODS: In 2010 and 2017, two large online surveys for MSM in Europe (EMIS-2010, EMIS-2017) collected self-reported data on STI diagnoses in the previous 12 months, diagnostic procedures, STI symptoms when testing, number of sexual partners, and sexual behaviours such as condom use during the last intercourse with a non-steady partner in 46 European countries. Multivariate regression models were used to analyse factors associated with diagnoses of syphilis, gonorrhoea/chlamydia, and respective diagnoses classified as symptomatic and asymptomatic. If applicable, they included country-level screening rates. RESULTS: Questions on STI diagnoses and sexual behaviours were answered by 156,018 (2010) and 125,837 (2017) participants. Between 2010 and 2017, overall diagnoses with gonorrhoea/chlamydia and syphilis increased by 76% and 83% across countries. Increases were more pronounced for asymptomatic compared to symptomatic infections. The proportion of respondents screened and the frequency of screening grew considerably. Condomless anal intercourse with the last non-steady partner rose by 62%; self-reported partner numbers grew. Increased syphilis diagnoses were largely explained by behavioural changes (including more frequent screening). Gonorrhoea/chlamydia increases were mainly explained by more screening and a change in testing performance. A country variable representing the proportion of men screened for asymptomatic infection was positively associated with reporting symptomatic gonorrhoea/chlamydia, but not syphilis. DISCUSSION/CONCLUSION: The positive association of country-level screening rates with the proportion of symptomatic infections with gonorrhoea/chlamydia may indicate a paradoxical effect of screening on incidence of symptomatic infections. Treatment of asymptomatic men might render them more susceptible to new infections, while spontaneous clearance may result in reduced susceptibility. Before expanding screening programmes, evidence of the effects of screening and treatment is warranted.

Sociodemographic and behavioural factors associated with testing for HIV and STIs in a US nationwide sample of transgender men who have sex with men.

OBJECTIVES: Transgender men who have sex with men (TMSM) represent an understudied population in relation to screening for HIV and sexually transmitted infections (STIs). We examined HIV and STI testing prevalence among TMSM along with the factors associated with testing in a diverse US nationwide sample of TMSM. METHODS: Data from a cross-sectional online convenience sample of 192 TMSM were analysed using multivariable binary logistic regression models to examine the association between sociodemographic and behavioural factors and lifetime testing for HIV, bacterial STIs and viral STIs, as well as past year testing for HIV. RESULTS: More than two-thirds of TMSM reported lifetime testing for HIV (71.4%), bacterial STIs (66.7%), and viral STIs (70.8%), and 60.9% had received HIV testing in the past year. Engaging in condomless anal sex with a casual partner whose HIV status is different or unknown and having fewer than two casual partners in the past 6 months were related to lower odds of lifetime HIV, bacterial STI, viral STI and past year HIV testing. Being younger in age was related to lower probability of testing for HIV, bacterial STIs and viral STIs. Furthermore, TMSM residing in the South were less likely to be tested for HIV and viral STIs in their lifetime, and for HIV in the past year. Finally, lower odds of lifetime testing for viral STIs was found among TMSM who reported no drug use in the past 6 months. CONCLUSIONS: These findings indicate that a notable percentage of TMSM had never tested for HIV and bacterial and viral STIs, though at rates only somewhat lower than among cisgender MSM despite similar patterns of risk behaviour. Efforts to increase HIV/STI testing among TMSM, especially among those who engage in condomless anal sex, are needed.

Manifestaciones coloproctológicas de las infecciones de transmisión sexual ocasionadas por Chlamydia Trachomatis, Neisseria Gonorrhoeae y Treponema Pallidum. Presentación casuística / Coloproctological manifestations of sexually transmitted infections caused by Chlamydia Trachomatis, Neisseria Gonorrhoeae and Treponema Pallidum. Case presentation

Introducción: Las infecciones transmisibles sexualmente (ITS) con afectación anorrectal constituyen un desafío pues las manifestaciones producidas por Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) y Treponema pallidum (TP) son similares. Objetivo: Evaluar si las manifestaciones anorrectales debidas a CT, NG y TP asociadas al examen proctológico permiten diagnóstico certero, sin estudios complementarios. Pacientes y método: Estudio retrospectivo. Revisión de registros de pacientes atendidos en consultorio coloproctológico. Periodo: 01/08/2015-01/07/2016. Se incluyeron pacientes con diagnóstico de ITS anorrectal, excepto aquellos con HPV únicamente. A todos se les pesquisaron ITS mediante hisopado anal para CT por inmunofluorescencia y para estudio directo y cultivo de NG, VDRL para TP y además HIV. Variables: sexo, edad, HIV, sexo anal, uso de preservativo, motivo de consulta y resultado de estudios efectuados. Resultados: Treinta y cuatro pacientes (32 hombres). Edad mediana 31,5 años (rango: 19-65). Veinticinco pacientes HIV + (73,5%). Veintinueve pacientes (28 hombres) mantenían sexo anal. 91% no usaba preservativo adecuadamente. 65% tuvo una única infección (ITS pura). Se diagnosticaron 14 sífilis (8 puras), 14 clamidiasis (7 puras) y 11 gonococcias (7 puras). Co-infección entre ellas: 9% y con HPV: 26%. La úlcera fue la manifestación en 7/8 casos de sífilis puras (todas dolorosas, excepto una). El resto presentó síntomas variados (condilomas virales atípicos, secreción purulenta y proctorragia). Más del 50% de las gonococias puras (4/7) se manifestó con úlcera, sin embargo, el dolor estuvo presente siempre (8/8) y en tres se asoció secreción purulenta. En cambio, la mitad de los pacientes con clamidiasis puras, se manifestó con proctorragia causada por un tumor rectal/sigmoideo inflamatorio, clínicamente indistinguible de neoplasia maligna. Todos las sífilis y gonococias tuvieron correlato con las pruebas diagnósticas, no así las clamidiasis cuyo diagnóstico no pudo confirmarse en tres casos (37,5%), que respondieron al tratamiento empírico. Conclusión: NG y TP anorrectal provocaron mayormente síntomas similares a los de etiología no venérea y se requirió del laboratorio para el diagnóstico etiológico. La presencia de tumor con biopsia negativa para neoplasia maligna en pacientes de riesgo para ITS obliga a descartar clamidiasis. (AU)

Introduction: Sexually transmitted infections (STIs) are a challenge in medical consultation. The clinical manifestations of infection by Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Treponema pallidum ( TP) share symptoms at anorectal level. This implies the need for a high index of suspicion for diagnosis, which is based on history, physical examination and laboratory tests that not always are accurate or available . Purpose: Assess whether clinical signs of anorectal infections by CT, NG and TP associated with proctologic exams, lead to an accurate etiologic diagnosis without the help of specific laboratory studies. Patients and methods: Observational, retrospective study, based on a review of records of patients treated at the outpatient clinic of the Hospital Fernandez (City of Buenos Aires) department of coloproctology, in the period between August 2015 and July 2016. Patients who underwent STI diagnosis were all considered, but to those whose only diagnosis was infection by human papilloma virus (HPV) were excluded from the analysis. All patients were tested after the three etiologies of STI (anal swab for CT study by immunofluorescence, swabbing for direct study, and cultivation of NG and TP VDRL) and HIV. Variables analyzed: sex, age, presence of HIV infection, practice of receptive anal sex, proper use of condoms, signs and symptoms that prompted the consultation, and results of diagnostic tests. Results: 34 patients (32 men) were included. Median age 31.5 years (range: 19-65, interquartile range: 26-37). Twenty-five patients (73.5%) were HIV+. Twenty-nine patients (28 men) remained receptive anal sex. 91% did not use condoms properly. 65% of infections were pure, without other STI asociada-. 14 cases of syphilis (8 pure), 14 Chlamydia (7 pure) and 11 gonococcias (7puras), including co-infection in 9% of cases, no evidence of a more frequent another co-infection diagnosed. Co-infection with HPV was detected in 9 (26%) cases. The ulcer was the sign in 7/8 cases of pure syphilis (all painful, except one). The rest is expressed by a variety of symptoms (atypical viral warts, purulent and bloody diarrhea). Similarly, just over 50% (4/7) of pure gonococcias demonstrated ulcer, but the pain was always present (8/8 of pure gonococcias) and three associated with purulent discharge. Instead of the ten patients with pure chlamydia, 50% manifested with bloody diarrhea caused by a rectal tumor / inflammatory sigmoid, clinically indistinguishable from malignancy. All cases of syphilis and gonococcal were correlated with diagnostic tests; not those whose diagnosis of chlamydial infection (confirmed in eight and was negative in three, 37.5%) who responded to empiric treatment indicated by the clinical suspicion. Conclusion: While this is a small series, it shows that the NG and TP in the anorectal location mostly caused symptoms similar to those of non-venereal ethology most of the times, and laboratory assistance for etiologic diagnosis was required. The presence of tumor with negative biopsy for malignancy in patients at risk for STIs, leads chlamydia to be ruled out. (AU)

A Systematic Literature Review of Reviews on the Effectiveness of Chlamydia Testing.

Chlamydia trachomatis is the most common bacterial sexually transmitted infection, causing significant morbidity and economic burden. Strategies like national screening programs or home-testing kits were introduced in some developed countries, yet their effectiveness remains controversial. In this systematic review, we examined reviews of chlamydia screening interventions to assess their effectiveness and the elements that contribute to their success to guide public policy and future research. We assessed English material published after 2000 in PubMed, the Cochrane Library, the British Nursing Index, Medical Database, and Sociological Abstracts, in addition to World Health Organization Global Health Sector Strategies, the European Center for Disease Prevention and Control guidelines, and the Prospective Register of Systematic Reviews. Systematic reviews that focused on chlamydia screening interventions were included. Using the socioecological model, we examined the levels of interventions that may affect the uptake of chlamydia screening. A total of 19 systematic reviews were included. Self-collection in home-testing kits significantly increased screening among girls and women 14-50 years of age. At the organizational level, using electronic health records and not creating additional costs facilitated testing. At the community level, outreach interventions in community and parent centers and homeless shelters achieved high screening rates. At the policy level, interventions with educational and advisory elements could result in significant improvements in screening rates.

Cribado de infecciones cervicales de transmisión sexual en mujeres embarazadas y su relación con la microbiota vaginal / Screening of cervical sexually transmitted infections in pregnant women and the relation with the vaginal microbiota

Resumen Introducción: La mujer embarazada está expuesta anumerosas infecciones de transmisión sexual (ITS), las que pueden producir aborto, enfermedad en el feto y/o en el recién nacido, además de alteraciones en el curso normal del embarazo. Objetivo: Realizar tamizaje de infección cervical asintomática en mujeres embarazadas y su relación con la microbiota. Pacientes y Métodos: Se enrolaron 85 mujeres embarazadas sin cervicitis clínica que consultaron en control de rutina de embarazo (47 pacientes) o que fueron derivadas a una unidad de ITS (38 pacientes). Se tomaron muestras de fondo de saco vaginal, que fueron analizadas por técnicas clásicas de microscopía y cultivo corriente y reacción de polimerasa en cadena para Neisseria gonorrhoeae, Trichomonas vaginalis y Chlamydia trachomatis. Resultados: Se encontró 12,9% de infección por C. trachomatis, 2,4% de T. vaginalis. En este estudio no se encontró N. gonorrhoeae. El 23,3% de pacientes con microbiota alterada (vaginosis bacteriana y microbiota intermedia) fue positiva para C. trachomatis. Conclusión: En este trabajo, encontramos una alta frecuencia de infección por C. trachomatis, que se relaciona en forma significativa con la presencia de microbiota alterada. Esta alta frecuencia debería promover estrategias preventivas en los controles de salud de la mujer embarazada.

Background: Pregnant woman is exposed to many sexual transmitted infections (STI). Many of these infections may produce diseases in the fetus and newborn, and also alteration in the normal course of the pregnancy. Aim: Screening of asymptomatic cervical infection in pregnant woman and its relationship with the vaginal microbiota. Patients and Methods: 85 pregnant women without clinical cervicitis who consult in the routine pregnant control (47 patients) and women derived from STI service (38 patients). The samples were obtained from the vaginal fund sac and were analyzed with optic microscopy, cultures and PCR of Neisseria gonorrhoeae, Trichomonas vaginalis and Chlamydia trachomatis. Results: 12,9% of the enrolled women were positive for C. trachomatis, 2,4% for T. vaginalis. In this study, we did not found N. gonorrhoeae. We observed 23,3% of patients with altered microbiota (bacterial vaginosis and intermediate microbiota) was positive for C. trachomatis. Conclusions: In this study, we found a high frequency of C. trachomatis infection, that correlates with the presence of altered microbiota. This high frequency would promote preventive strategies in the pregnant women routine controls.

Bacterial sexually transmitted infections in France: recent trends and patients' characteristics in 2016.

Diagnoses of bacterial sexually transmitted infections (STI) have been increasing in France since their resurgence in the late 1990s. This article presents recent epidemiological trends until 2016 and the patients' characteristics. STI surveillance relies on sentinel networks: a clinician-based network RésIST (clinical, biological and behavioural data for early syphilis and gonorrhoea), the lymphogranuloma venereum (LGV) network (clinical, biological and behavioural data for rectal LGV, and the laboratory networks Rénachla and Rénago (demographic and biological data for chlamydial infections and gonorrhoea, respectively). Here we describe trends between 2014 and 2016, using data from diagnostic centres which participated regularly during the study period. The number of early syphilis, gonorrhoea and LGV diagnoses increased between 2014 and 2016, particularly in men who have sex with men. An increase in syphilis and gonorrhoea cases was also observed in heterosexuals. Nevertheless, we observed a drop in 2016 for syphilis and chlamydial infections after two decades of increases. Under-reporting and shortage of benzathine penicillin in 2016 may explain this latest evolution. Regular screening of patients and partners, followed by prompt treatment, remains essential to interrupt STI transmission in a context where human immunodeficiency virus (HIV) prevention has expanded towards biomedical prophylaxis.

Bacterial Sexually Transmitted Infection Screening Rates by Symptomatic Status Among Men Who Have Sex With Men in the United States: A Hierarchical Bayesian Analysis.

BACKGROUND: Prevention of bacterial sexually transmitted infections (STIs) among men who have sex with men (MSM) requires timely disease detection, but this is complicated by asymptomatic infection. We estimated screening/testing rates by symptomatic status to evaluate adherence to Centers for Disease Control and Prevention STI screening guidelines. METHODS: In a cross-sectional study of 2572 US MSM aged 15 to 65 years in 2017 to 2018, we measured the reported number of asymptomatic STI screens in the past 2 years versus tests prompted by disease symptoms. Using negative binominal regression within a hierarchical Bayesian framework, we estimated yearly rates of asymptomatic screening and symptomatic testing by geographic, demographic, and behavioral factors. RESULTS: Human immunodeficiency virus (HIV) status was most strongly associated with all testing/screening frequency (incidence rate ratio [IRR], 1.72; 95% credible interval [Crl], 1.49, 1.97). The HIV-uninfected MSM had 0.14 (95% credible interval [CrI], 0.12-0.17) symptomatic tests and 0.88 (95% CrI, 0.77-1.01) asymptomatic screens per year. The HIV-infected MSM had 0.25 (95% CrI, 0.18-0.35) symptomatic tests and 1.53 (95% CrI, 1.24-1.88) asymptomatic screens per year. Rates of asymptomatic screening were higher among black compared with white MSM (IRR, 1.41; 95% CrI, 1.15-1.73), but weakly associated with number of past-year sexual partners (IRR, 1.01; 95% CrI, 1.00-1.01). Overall, 85% to 90% of diagnostic events were asymptomatic screens. CONCLUSIONS: Self-reported rates of STI screening were close to Centers for Disease Control and Prevention's recommended overall annual screening frequency, but with gaps defined by demographics and behavioral risk. Targeted screening efforts may be indicated specifically for younger MSM and those with multiple partners.

A service evaluation comparing home-based testing to clinic-based testing for Chlamydia and gonorrhoea in Birmingham and Solihull.

Home-based testing is an alternative, convenient and cost-effective method of testing for sexually transmitted infections compared to traditional clinic-based testing, in patients who are asymptomatic and, or, would otherwise feel stigmatised about attending sexual health clinics. The sexual health service in Birmingham and Solihull, called Umbrella, provides an online home-based testing service, which has been in operation since August 2015. The aim of this study was to evaluate the uptake and return rate of home-based testing kits and compare home-based testing to clinic-based testing in terms of diagnosis and treatment rates of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC). Our study showed that home-based testing is a popular method of testing and relatively more popular amongst asymptomatic, young, heterosexual female and White patients than clinic-based testing, with a return rate of 48%. The diagnosis rates for CT/GC are comparable to patients who attend clinic for testing (8% vs. 10% in home-based and clinic-based groups, respectively, p < 0.001). The overall treatment rate was lower in the home-based compared to the clinic-based group (82% vs. 88%, p < 0.001). Umbrella will continue to provide this service within Birmingham and Solihull and aim to provide patients with alternative pathways for more convenient access to treatment.

[Diagnosis of vaginal discharge].

Changes in vaginal discharge are often caused by imbalance in the vaginal microflora, and laboratory testing is usually of little use, as most microbes detected are commensals. In-office diagnosis in general practice using wet mount microscopy and Amsel criteria is helpful and often sufficient to ensure correct diagnosis and treatment. Laboratory testing of vaginal discharge should only be performed, if sexually transmitted disease is suspected, if there is treatment failure or inconclusive wet mount prior to gynaecological surgery, and in pregnant women with recurrent miscarriage or preterm birth.

Sexually Transmitted Infection Testing of HIV-Positive Medicare and Medicaid Enrollees Falls Short of Guidelines.

BACKGROUND: Men who have sex with men with HIV have high sexually transmitted infection (STI) incidence. Thus, the Centers for Disease Control and Prevention (CDC) recommends at least yearly STI screening of HIV-infected individuals. METHODS: We calculated testing rates for syphilis, chlamydia, and gonorrhea among HIV-positive Californians with Medicare or Medicaid insurance in 2010. Logistic regressions estimated how testing for each bacterial STI relates to demographic and provider factors. RESULTS: Fewer than two-thirds of HIV-positive Medicare and fewer than three-quarters of Medicaid enrollees received a syphilis test in 2010. Screenings for chlamydia or gonorrhea were less frequent: approximately 30% of Medicare enrollees were tested for chlamydia or gonorrhea in 2010, but higher proportions of Medicaid enrollees were tested (45%-46%). Only 34% of HIV-positive Medicare enrollees who were tested for syphilis were also screened for chlamydia or gonorrhea on the same day. Nearly half of Medicaid enrollees were tested for all 3 STIs on the same day. Patients whose providers had more HIV experience had higher STI testing rates. CONCLUSIONS: Testing rates for chlamydia and gonorrhea infection are low, despite the increase in these infections among people living with HIV and their close association with HIV transmission. Interventions to increase STI testing include the following: prompts in the medical record to routinely conduct syphilis testing on blood drawn for viral load monitoring, opt-out consent for STI testing, and provider education about the clinical importance of STIs among HIV-positive patients. Last, it is crucial to change financial incentives that discourage nucleic acid amplification testing for rectal chlamydia and gonorrhea infections.

Sexually Transmitted Disease Testing of Human Immunodeficiency Virus-Infected Men Who Have Sex With Men: Room for Improvement.

BACKGROUND: In the United States, sexually transmitted infection (STI) testing is recommended at least annually for sexually active men who have sex with men (MSM). We evaluated human immunodeficiency virus (HIV) providers' STI testing practices and frequency of positive test results. METHODS: We analyzed data from HIV Outpatient Study (HOPS) participants who, from 2007 to 2014, completed a confidential survey about risk behaviors. Using medical records data, we assessed the frequency of gonorrhea, chlamydia, and syphilis testing and positive results during the year after the survey for MSM who reported sex without a condom in the prior 6 months. We compared testing frequency and positivity for men having 1, 2 to 3, and 4 or more sexual partners. Correlates of STI testing were assessed using general linear model to derive relative risks (RR) with associated 95% confidence intervals (CI). RESULTS: Among 719 MSM, testing frequency was 74.5%, 74.3%, and 82.9% for gonorrhea, chlamydia, and syphilis, respectively, and was higher in those men who reported more sexual partners (P < 0.001 for all). In multivariable analysis, testing for gonorrhea was significantly more likely among non-Hispanic black versus white men (RR, 1.17; 95% CI, 1.03-1.33), among men seen in private versus public clinics (RR, 1.16; 95% CI, 1.05-1.28), and among men with 2 to 3 and 4 or more sexual partners versus 1 partner (RR, 1.12; 95% CI, 1.02-1.23, and RR, 1.18; 95% CI, 1.08-1.30, respectively). Correlates of chlamydia and syphilis testing were similar. Test positivity was higher among men with more sexual partners: for gonorrhea 0.0%, 3.0%, and 6.7% for men with 1, 2 to 3, and 4 or more partners, respectively (P < 0.001, syphilis 3.7%, 3.8% and 12.5%, P < 0.001). CONCLUSIONS: Among HIV-infected MSM patients in HIV care who reported sex without a condom, subsequent testing was not documented in clinic records during the following year for up to a quarter of patients. Exploring why STI testing did not occur may improve patient care.

Adolescentes encuentran fácil tomar sus propias muestras para estudio de infecciones de transmisión sexual / Adolescents find it easy to collect their own samples to study sexually transmitted infections

Background: As alternative for patients that fear genital examination, we assessed adolescent's comfort and ease with self-collected samples for nucleic acid amplification testing for sexually transmitted infections. Patients and Methods: Sexually active Chilean adolescents and youth under 25 years (174 males and 117 females) were enrolled. Females used self-collected vaginal swabs and males collected first-stream urine. A satisfaction survey evaluating self-sampling system was applied. Results: Self-collection was considered easy in 99.3% of the interviewees (CI 95% 0.88-0.98). In women, 79.3% preferred vaginal self-collected samples than pelvic exam (CI 95% 0.73-0.85). In men, 80.3% preferred self-collected first-stream urine to urethral swabs (CI 95% 0.73-0.87). Assuming that self-collected sampling were available, 89.6% of women (CI 95% 0.85-0.94) and 93.2% of men (CI 95% 0.89-0.98) would be prone to be tested more often. Ease of self-collected sampling is not associated with age, gender, educational level or poverty. Conclusions: Chile currently does not have sexually transmitted infections surveillance or screening programs for youth and adolescents. Given self-collected sampling's good acceptability, it could be successfully used when these programs are implemented.

Introducción: Como alternativa para pacientes que temen al examen genital o para aquellos asintomáticos, se evaluó la satisfacción de adolescentes con el sistema de autotoma -muestra tomada por el propio paciente- para amplificación de ácidos nucleicos y determinación de infecciones de transmisión sexual (ITS). Material y Método: Se enrolaron 174 mujeres y 117 hombres menores de 25 años sexualmente activos. Las mujeres se realizaron autotoma con tórula vaginal. Los hombres, autotoma de orina de primer chorro. Se aplicó encuesta de satisfacción. Resultados: A 99,3%, le resultó fácil obtener muestras mediante autotoma (IC 95% 0,88-0,98). En mujeres, 79,3% prefirió la autotoma vaginal por sobre el examen pélvico (IC 95% 0,73-0,85). En hombres, 80,3% prefirió la autotoma de orina por sobre el hisopado uretral (IC 95% 0,73-0,87). Si la autotoma estuviera disponible, 89,7% de las mujeres (IC 95% 0,85-0,94) y 93,2% de los hombres (IC 95% 0,89-0,98) estarían dispuestos a someterse a un examen de ITS en forma más seguida. Encontrar fácil la autotoma no se asoció con edad, género, escolaridad ni pobreza. Conclusiones: Chile aún no tiene programas de vigilancia o detección de ITS para jóvenes y adolescentes. Dada la buena aceptabilidad de la autotoma, se podría emplear exitosamente cuando estos programas se implementen.

Frequency and determinants of consistent STI/HIV testing among men who have sex with men testing at STI outpatient clinics in the Netherlands: a longitudinal study.

OBJECTIVES: Men who have sex with men (MSM) are at highest risk for STIs and HIV infections in the Netherlands. However, official guidelines on STI testing among MSM are lacking. They are advised to test for STIs at least every six months, but their testing behaviour is not well known. This study aimed to get insight into the proportion and determinants of consistent 6-monthly STI testing among MSM testing at STI outpatient clinics in the Netherlands. METHODS: This study included longitudinal surveillance data of STI consultations among MSM from all 26 STI outpatient clinics in the Netherlands between 1 June 2014 and 31 December 2015. Multinomial logistic regression analysis was used to identify determinants of consistent 6-monthly testing compared with single testing and inconsistent testing. Determinants of time between consultations among men with multiple consultations were analysed using a Cox Prentice-Williams-Peterson gap-time model. RESULTS: A total of 34 605 STI consultations of 18 634 MSM were included. 8966 (48.1%) men had more than one consultation, and 3516 (18.9%) men tested consistently 6-monthly. Indicators of high sexual risk behaviour, including having a history of STI, being HIV positive and having more than 10 sex partners, were positively associated with both being a consistent tester and returning to the STI clinic sooner. Men who were notified by a partner or who reported STI symptoms were also more likely to return to the STI clinic sooner, but were less likely to be consistent testers, identifying a group of event-driven testers. CONCLUSIONS: The proportion of consistent 6-monthly testers among MSM visiting Dutch STI outpatient clinics was low. Testing behaviour was associated with sexual risk behaviour, but exact motives to test consistently remain unclear. Evidence-based testing guidelines are needed to achieve optimal reductions in STI transmission in the future.

Barriers to Bacterial Sexually Transmitted Infection Testing of HIV-Infected Men Who Have Sex With Men Engaged in HIV Primary Care.

BACKGROUND: Approximately 15% of HIV-infected men who have sex with men (MSM) engaged in HIV primary care have been diagnosed as having a sexually transmitted infection (STI) in the past year, yet STI testing frequency remains low. METHODS: We sought to quantify STI testing frequencies at a large, urban HIV care clinic, and to identify patient- and provider-related barriers to increased STI testing. We extracted laboratory data in aggregate from the electronic medical record to calculate STI testing frequencies (defined as the number of HIV-infected MSM engaged in care who were tested at least once over an 18-month period divided by the number of MSM engaged in care). We created anonymous surveys of patients and providers to elicit barriers. RESULTS: Extragenital gonorrhea and chlamydia testing was low (29%-32%), but the frequency of syphilis testing was higher (72%). Patients frequently reported high-risk behaviors, including drug use (16.4%) and recent bacterial STI (25.5%), as well as substantial rates of recent testing (>60% in prior 6 months). Most (72%) reported testing for STI in HIV primary care, but one-third went elsewhere for "easier" (42%), anonymous (21%), or more frequent (16%) testing. HIV primary care providers lacked testing and treatment knowledge (25%-32%) and cited lack of time (68%), discomfort with sexual history taking and genital examination (21%), and patient reluctance (39%) as barriers to increased STI testing. CONCLUSION: Sexually transmitted infection testing in HIV care remains unacceptably low. Enhanced education of providers, along with strategies to decrease provider time and increase patient ease and frequency of STI testing, is needed.
