Epidemiological Characteristics and Factors Associated with Repeat Sexually Transmitted Infections in Barcelona, Spain Over a Decade.

In the last few years, the frequency of sexually transmitted infections (STI) has increased, as has the number of people with multiple infections. The aim of our study was to describe the epidemiological characteristics of persons with repeated bacterial STI and to determine the risk factors for these episodes in persons living in Barcelona during the period 2007-2018. We studied all cases of bacterial STI included in the STI registry of Barcelona. Repeated STI were defined as a diagnosis of gonorrhea, syphilis, or lymphogranuloma venereum (LGV) after a first episode of one of these infections. Analysis was stratified by sex and place of birth. The factors associated with time to reinfection were determined by Kaplan-Meier estimates, while the factors associated with risk of infection were determined by a Cox proportional hazards model. Of 9927 persons with a diagnosis of bacterial STI, 1690 (17.0%) had at least two episodes of STI during the study period. On multivariate analysis, repeat STI were independently associated with male sex assigned at birth (HR: 3.45; 95%CI 2.22-5.36), age less than 34 years (HR: 1.22; 95%CI 1.10-1.35); gay, bisexual, and other men who have sex with men, and transgender o transsexual woman (GBSMS/Trans) (HR: 4.03; 95%CI 3.24-5.03), having gonorrhea as first diagnosis (HR:1.49, 95%CI 1.34-1.66) or LGV (HR:1.75; 95%CI 1.47-2.08) and coinfection with HIV (HR:1.98; 95%CI 1.78-2.21). Sexual health programs should be strengthened to prevent STI and reinfection in key populations.

Neisseria meningitidis y el aumento del sexo oral. A propósito de un caso / Neisseria meningitidis and the increase of oral sex. A case report

La uretritis es una entidad caracterizada por disuria y secreción uretral purulenta, generalmente adquirida por vía sexual. Neisseria gonorrhoeae es uno de los microorganismos más frecuentemente responsables. Neisseria meningitidis es un diplococo gramnegativo aislado habitualmente en la faringe, que causa en ocasiones meningitis meningocócica, siendo poco común aislarlo en el área anogenital, donde podría ser patógeno genitourinario. Presentamos el caso de un hombre heterosexual de 25 años que tras una relación heterosexual con una pareja ocasional no profesional que incluyó sexo oral y vaginal presenta clínica de uretritis, orientándose como infección de transmisión sexual. El cultivo bacteriológico convencional para N. gonorrhoeae fue negativo, siendo la PCR para Chlamydia trachomatis positiva. Posteriormente, el laboratorio informó de un cultivo bacteriológico positivo para N. meningitidis serogrupo C, sensible a ceftriaxona, y PCR negativa para N. gonorrhoeae. N. meningitidis es la principal causa de meningitis bacteriana, pero estudios genómicos evidencian que alelos de la nitrato reductasa, la proteína ligadora del factor-H y la cápsula están asociados con aislamientos de N. meningitidis en infecciones genitourinarias. La transmisión desde orofaringe a uretra a través del contacto orogenital en el sexo oral desprotegido ha sido ampliamente demostrada. La prevalencia de N. meningitidis como causante de uretritis es baja, siendo los portadores asintomáticos en uretra muy raros. La PCR es un método para el diagnóstico de N. gonorrhoeae y C.trachomatis, pero no detecta N. meningitidis. El diagnóstico de gonorrea se basa en un número aumentado de polimorfonucleares con diplococos gramnegativos intracelulares en tinción de Gram de secreción uretral. En nuestro caso, el diplococo gramnegativo visualizado en la tinción fue meningococo. (AU)

Urethritis is an entity characterized by dysuria and purulent urethral discharge, generally acquired sexually. Neisseria gonorrhoeae is one of the most frequently responsible microorganisms. Neisseria meningitidis is a gram-negative diplococcus usually isolated in the pharynx, that occasionally causes meningococcal meningitis, being unusual it's isolation in the anogenital area where it could be a genitourinary pathogen. We present the case of a 25-years-old heterosexual male who, after a heterosexual intercourse with an occasional non-professional partner, including oral and vaginal sex, presented with symptoms of urethritis, orienting to a sexually transmitted infection. The bacteriological culture for N. gonorrhoeae was negative and the PCR for Chlamydia trachomatis was positive. Subsequently, the lab reported a positive bacteriological culture for sero-group C N. meningitidis, sensitive to ceftriaxone and a negative PCR for N. gonorrhoeae. N. meningitidis is the main cause of bacterial meningitis, but genomic studies have suggested that alleles of nitrate reductase, factor-H biding protein and capsule are associated with N. meningitidis isolation in genitourinary infections. Transmission from the oropharynx to the urethra through orogenital contact in unprotected oral sex has been widely proven. N. meningitidis prevalence as the cause of the urethritis is low, and the asymptomatic carriers in the urethra are extremely rare. PCR is a method for the N. gonorrhoeae and C.trachomatis diagnoses, but it does not detect N. meningitidis. The gonorrhoea diagnosis is based on an increased number of polymorphonuclear cells, with intracellular gram-negative diplococci in Gram’ stain of urethral discharge. In our case, the gram-negative diplococcus seen in the stain was a meningococcus. (AU)

Urethritis due to N. meningitidis is indistinguishable from the secondary to N. gonorrhoeae, mimicking it even microscopically, only the epidemiology varies. The conventional bacteriological culture continues to be essential for a correct diagnosis.

Epidemiological, clinical and laboratory differences between male urethral infections due to Haemophilus spp. and those due to Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium and Ureaplasma urealyticum: A descriptive study.

OBJECTIVE: To describe the epidemiological, clinical and laboratory characteristics of male patients diagnosed with Haemophilus spp. urethral infection and to compare them with the characteristics of male patients diagnosed with N. gonorrhoeae, C. trachomatis, M. genitalium and U. urealyticum urethral infection. Over the past 2 years, an increase in urethral infections due to Haemophilus spp. was observed. MATERIALS AND METHODS: All male patients who attended our Department of Sexually Transmitted Infections between January 2018 and February 2019 were retrospectively studied; they underwent conventional bacteriological and multiplex PCR studies in the urethra at the same time. RESULTS: Of the 86 patients studied, a unique microorganism was detected in 76 cases, N. gonorrhoeae in 24, Haemophilus spp. in 21 (16 H. parainfluenzae and 5 H. influenzae), C. trachomatis in 19, M. genitalium in 8 and U. urealyticum in 4; 10 cases presented more than one microorganism. In case of multiple aetiological agents, sexual partnership was multiple. In the Haemophilus group, 81% reported only unprotected oral insertive sex; symptoms lasted for more than one week in 62% of the patients. CONCLUSIONS: Haemophilus is an aetiological agent of non-gonococcal urethritis whose incidence is clearly increasing; the main route of transmission is oral sex. The most common reason for consultation is dysuria and testicular pain, while urethral discharge was predominant for the other causes of urethral infection. Due to the high frequency of antibiotic resistance in the Haemophilus group, it is necessary to confirm eradication by performing a test of cure.

Haemophilus urethritis in males: A series of 30 cases.

INTRODUCTION AND OBJECTIVES: Pathogens such as Haemophilus spp. have been associated with non-gonococcal urethritis, but their role is unproven. To describe the clinical characteristics and therapeutic outcomes in male patients diagnosed with Haemophilus spp. urethritis. METHODS: We carried out a retrospective study of all patients who presented to our hospital (in either the emergency department or the outpatient clinic) between July 2016 and April 2018 in whom Haemophilus spp. was isolated in the urethral samples. We enrolled 30 men with Haemophilus spp.-positive urethritis, including coinfections with Neisseria gonorrhoeae and Chlamydia trachomatis. Clinical, laboratory, demographic, and behavioral data were obtained by reviewing medical histories. RESULTS: The mean age of the patients was 36.6 years (range 21-87). Seventeen patients (63%) reported being exclusively heterosexual. Three patients (10%) were HIV infected, all of them with an undetectable viral load. The most common clinical presentation was mucopurulent urethral discharge, in 13 patients (43%). The antibiotic treatment achieved a complete clinical resolution in 73%. CONCLUSIONS: Haemophilus urethritis affected men regardless of their sexual orientation or HIV status. Unprotected oral sex may play a role in its transmission. The limitations of the study preclude verification of the pathogenic role of Haemophilus spp. in acute urethritis, but clinical response after antibiotic treatment suggests that Haemophilus spp. can play such a role.

Clinical factors affecting semen improvement after microsurgical subinguinal varicocelectomy: which subfertile patients benefit from surgery?

BACKGROUND: The exact mechanism of varicocele-related infertility is still elusive, therefore, the current challenges for its management lie in determining which patients stand to benefit most from surgical correction. The authors aimed to assess the clinical factors affecting semen improvement after left microsurgical subinguinal varicocelectomy (MSV) in relation to patient age, ultrasound varicocele grading (USVG), and presence of a right subclinical varicocele (RSV). METHODS: From 2010 to 2017 a total of 228 infertile patients underwent left MSV for clinical varicocele. Descriptive statistics were used to describe the cohort and verify the surgical benefit in terms of semen improvement, in addition, subsets of patients were selected according to clinical covariates. Logistic regression modeling was applied to evaluate the presence of RSV, operative time, age, and USVG as explanatory variables. RESULTS: Sperm concentration (SC), progressive sperm motility (PSM), and normal sperm morphology (NSM) increased significantly after surgery (p = 0.002; p = 0.011; p = 0.024; respectively). Mean SC improved after MSV in ⩾35 year-old patients and the grade 3 USVG group (p = 0.01; p = 0.02; respectively). Logistic regression modeling showed a that the probability of SC improvement was 76% lower in subjects presenting RSV (p = 0.011). In addition, patients with a grade 3 USVG presented a three-times greater probability of SC improvement compared with patients with a lower USVG (p = 0.035). In addition, older patients showed a greater probability of SC improvement after MSV (p = 0.041). CONCLUSIONS: MSV is an effective varicocele-related infertility treatment that should also be offered to older patients. In addition, patients with a higher USVG benefit from surgery. In infertile men with an RSV in association with a left clinical disease, a bilateral varicocele repair should be considered.

Sexually transmitted infections in young people and factors associated with HIV coinfection: an observational study in a large city.

OBJECTIVES: Young people are a critical target group for sexually transmitted infections (STI) surveillance due to their particular behavioural and social related vulnerability. The aim of this study was to describe the epidemiological characteristics and trends in the incidence of gonorrhoea, syphilis, HIV and venereal lymphogranuloma (LGV) among 15-24-year-olds in Barcelona, and to determine factors associated with HIV coinfection. DESIGN: We performed a population-based incidence study covering the 2007-2015 period. PARTICIPANTS: All new cases of STI-HIV, gonorrhoea, infectious syphilis and LGV-notified to the epidemiological surveillance system in Barcelona between 2007 and 2015. 1218 cases were studied: 84.6% were men, 19.3% were 15-19 years old and 50.6% were born in Spain. Among men, 73.7% were men who have sex with men (MSM); among women, 85.6% were women that have sex with men. PRIMARY AND SECONDARY OUTCOMES: Incidence of HIV, gonorrhoea, infectious syphilis and LGV. HIV coinfection. RESULTS: There was an increase in the incidence of gonorrhoea, from 1.9 cases per 10 000 people in 2007 to 7.6/10 000 in 2015 (p<0.01), in MSM from 27.1 to 228.8/10 000 (p<0.01). The incidence of syphilis increased from 0.4/10 000 in 2007 to 3.1/10 000 in 2015 (significant in men only, p<0.01), in MSM from 18.1 to 116.9/10 000 (p<0.01). The incidence of HIV showed a non-significant increase in men (p=0.27), and that of LGV remained stable (p=0.59). Factors associated with increased risk of HIV coinfection included being MSM (adjusted OR[ORa]=14.14, 95% CI 3.34 to 59.91) and having >10 sexual partners (ORa=4.11, 95% CI 1.53 to 11.01) or STI diagnosis during the previous 12 months (ORa=2.06; 95% CI 1.13 to 3.77). CONCLUSIONS: The incidence of gonorrhoea and syphilis among 15-24-year-olds increased, while HIV infection remained stable but with a high incidence among MSM. Being MSM, having sex with multiple partners and having a diagnosis of an STI in the previous 12 months were factors associated with HIV coinfection.

Gay Circuit Parties in Barcelona and Their Impact on Gonorrhea Incidence.

This study explored the role of circuit parties on the incidence of gonorrhea among men who have sex with men (MSM) in Barcelona (Spain). Specifically, it aimed to detect cyclic peaks in the number of reported diagnoses of gonorrhea after gay circuit parties. We analyzed monthly cases of gonorrhea reported from January 2007 through December 2016 after the main annual gay circuit parties in Barcelona. We used the integer autoregressive model for time series with discrete values. The performance of the model was tested in heterosexual men and women, in whom the circuit parties could be expected to have no impact. A sensitivity analysis was conducted, changing post-event diagnosis windows to 1 week later/1 week before. In the study period, a total of 4182 of gonorrhea cases were detected, of which 74.8% (n = 2181) occurred in men who identified themselves as MSM. The average annual increase in gonorrhea cases reported among MSM was 32.57%. In an independent analysis of each gay circuit party, cases increased significantly in two of them. The results were also similar for same-sex practices among men only. On controlling for the increasing trend over the study period and the seasonal effect, an average of 1.16 gonorrhea cases in MSM (95% CI: 0.68, 1.64) were attributable to the celebration of one of the gay circuit parties considered. During the expected outbreak, an average of 13 gonorrhea cases were detected and between 5 and 13% were attributable to one of the circuit parties. In view of these findings, participants should consider seeking advice from their healthcare provider and practice safer sex using condoms to prevent sexually transmitted infections. Local public health services should be reinforced to ensure care for participants during and after gay circuit parties. More research is needed to design and implement preventive programs.

Factors predicting success after microsurgical vasovasostomy.

PURPOSE: To identify factors predicting success and analyze critically the status of microsurgical double-layer vasovasostomy using predictive models. METHODS: A cohort of 263 patients treated at our institution for vasectomy reversal between 1986 and 2010 was included in our study, and the literature was reviewed. Inclusion criteria were previous bilateral vasectomy and presence of at least two postoperative semen analyses; patients reporting pregnancy without a postoperative semen analysis were excluded. A double-layer, microscope-assisted, tension-free anastomosis vasovasostomy was performed approximating mucosa to mucosa and muscle to muscle with a 10-0 non-absorbable suture. A multivariate logistic regression backward stepwise model was used to predict combined success, and a predictive model was calculated with remaining variables. RESULTS: Mean age was of 41.6 years (SD 7.1); mean duration of obstruction 7.2 years (SD 6.7). On multivariate analysis, uni- or bilateral granuloma and Silber grade of I-III were variable identified predicting higher probability to success (OR 3.105; 95% CI 1.108-8.702; p = 0.031 and OR 4.795; 95% CI 2.117-10.860; p < 0.001, respectively). CONCLUSIONS: Based on our results, some factors predicting success after vasovasostomy surgery are known but others remain unknown; our predictive model may easily predict patency and success after this surgery and offers a concrete assistance in counseling patients.

Urethral condylomas in men: experience in 123 patients without previous treatment.

The most common sexually transmitted infection (STI) is infection by human papillomavirus. There are more than 100 types of human papillomavirus, and over 30 of them involve the genital area. Urethral involvement is uncommon and usually limited to the distal 3 cm of the meatus. There are various treatments for urethral condylomas; as a rule, they are limited by a difficult approach, by recurrences, and by potential complications, the most significant of which is urethral stenosis. The purpose of the treatments is to remove the warts and induce lesion-free periods. Such treatments do not eliminate the infection nor do they prevent continued transmission of the virus. We retrospectively evaluated 123 patients diagnosed and treated for condylomas in the genital area at our Institution between April 2009 and April 2012. The patients' mean age was 28.7 years (range 19-51). Of the 123 patients included, 48 (39%) had a history of previous STIs, most frequently gonococcal urethritis. Three of them had a urethral malformation in the form of hypospadias, and another three reported a previous urologic manipulation (catheterisation). Meatal/urethral condylomas are rare, cryotherapy is simple, easy to apply, and has a very low risk of complications in patients with externally accessible warts.

Epidemiology of infections by HIV, Syphilis, Gonorrhea and Lymphogranuloma Venereum in Barcelona City: a population-based incidence study.

BACKGROUND: The aim of this study was to determine the evolution of HIV infection, gonorrhea, syphilis and lymphogranuloma venereum (LGV), and their epidemiological characteristics in Barcelona city. METHODS: Population-based incidence study of all newly occurring diagnoses of HIV infection, syphilis, gonorrhea and LGV detected in Barcelona between January 2007 and December 2011. A descriptive analysis was performed. The annual incidence rates per 100,000 inhabitants were calculated by sex, sexual conduct and educational level. To estimate global sex-specific rates we used the Barcelona city census; for the calculation of rates by sexual conduct and educational level we used estimates of the Barcelona Health Interview Survey. Trends were analysed using the chi-squared test for linear trend. RESULTS: HIV. 66.8 % of the HIV cases were men who had sex with men (MSM). The incidence rates in MSM over the study period were from 692.67/100,000 to 909.88/100,000 inh. Syphilis. 74.2 % of the syphilis cases were MSM. The incidence rates in MSM were from 224.9/100,000 to 891.97/100,000 inh. and the MSM with a university education ranged from 196.3/100,000 to 1020.8/100,000. Gonorrhea. 45.5 % of the gonorrhea cases were MSM. The incidence rates in MSM were from 164.24/100,000 to 404.79/100,000 inh. and the MSM with university education ranged from 176.7/100,000 to 530.1/100,000 inh.. Lymphogranuloma venereum (LGV). 95.3 % of the LGV cases are MSM. The incidence rates in MSM were from 24.99/100,000 to 282.99/100,000 inh. and the MSM with university education ranged from 9.3/100,000 to 265/100,000 inh. CONCLUSION: An increase in cases of STI was observed. These STI mainly affected MSM with a university education. Continuing to monitor changes in the epidemiology of STI, and identifying the most affected groups should permit redesigning preventive programs, with the goal of finding the most efficient way to reach these population groups.

Clinical relevance of Y-linked CNV screening in male infertility: new insights based on the 8-year experience of a diagnostic genetic laboratory.

AZF microdeletion screening is routinely performed in the diagnostic work-up for male infertility; however, some issues remain debated. In this study, we provide insights into the sperm concentration cutoff value for routine testing, the predictive value of AZFc deletion for testicular sperm retrieval and the Y-background contribution to the interpopulation variability of deletion frequencies. In the Spanish population, partial AZFc rearrangements have been poorly explored and no data exist on partial duplications. In our study, 27/806 (3.3%) patients carried complete AZF deletions. All were azoo/cryptozoospermic, except for one whose sperm concentration was 2 × 10(6)/ml. In AZFc-deleted men, we observed a lower sperm recovery rate upon conventional TESE (9.1%) compared with the literature (60-80% with microTESE). Haplogroup E was the most represented among non-Spanish and hgr P among Spanish AZF deletion carriers. The analysis of AZFc partial rearrangements included 330 idiopathic infertile patients and 385 controls of Spanish origin. Gr/gr deletion, but not AZFc partial duplications, was significantly associated with spermatogenic impairment. Our data integrated with the literature suggest that: (1) routine AZF microdeletion testing could eventually include only men with ≤2 × 10(6)/ml; (2) classical TESE is associated with low sperm recovery rate in azoospermic AZFc-deleted men, and therefore microTESE should be preferred; (3) Y background could partially explain the differences in deletion frequencies among populations. Finally, our data on gr/gr deletion further support the inclusion of this genetic test in the work-up of infertile men, whereas partial AZFc duplications do not represent a risk for spermatogenic failure in the Spanish population.

[Reemergence of infectious syphilis among homosexual men and HIV coinfection in Barcelona, 2002-2003]. / Reemergencia de la sífilis infecciosa en varones homosexuales y coinfección por el virus de la inmunodeficiencia humana en Barcelona, 2002-2003.

BACKGROUND AND OBJECTIVES: An increase in syphilis infections since the mid 1990s has been documented, especially in homosexual men, in different European and North American cities. We intended to describe the characteristics of newly diagnosed cases of syphilis at the Sexually Transmitted Infections Unit of Barcelona in 2002 and 2003. PATIENTS AND METHOD: Descriptive analysis of cases with infectious syphilis and multivariate analysis of factors associated with HIV coinfection. RESULTS: 102 cases were diagnosed with infectious syphilis, 98 males (88 homosexual men). HIV coinfection was present in 34% of cases. Predictive factors of HIV coinfection were age > 30 years (p = 0.003) and having a HIV positive partner (p = 0.044). Clinically, there were no differences between cases coinfected or not with HIV. CONCLUSIONS: There has been a recent increase of syphilis in Barcelona, especially among some core groups of homosexual men with high rates of HIV coinfection.
