Among them, HCV prevalence and bio-behavioural data are scarce for HIV-negative men who have sex with men (MSM) and men and trans-women sex workers. We sought to describe and assess the potential benefits of a community-based one-step HCV screening and confirmatory strategy for these populations in Barcelona. The screening strategy based on a real-time RT-PCR assay for HCV-RNA detection in dried-blood spots (DBS) was validated and implemented in addition to an antibody point-of-care test in a community centre. HCV prevalence was assessed, and bio-behavioural data were collected. The molecular assay was precise, reproducible, sensitive and specific. Four HIV-negative MSM reported being currently infected (0.75% HCV self-reported prevalence). Implementation of DBS testing was easy, and acceptability was >95%, but no silent HCV case was diagnosed (N =...

COVID-19 surveillance of workers in oncological centres is crucial to assess infection burden and prevent transmission. We estimate the SARS-CoV-2 seroprevalence among healthcare workers (HCWs) of a comprehensive cancer centre in Catalonia, Spain, and analyse its association with sociodemographic characteristics, exposure factors and behaviours. Design: Cross-sectional study (21 May 2020-26 June 2020). Setting: A comprehensive cancer centre (Institut Català d'Oncologia) in Catalonia, Spain. Participants: All HCWs (N=1969) were invited to complete an online self-administered epidemiological survey and provide a blood sample for SARS-CoV-2 antibodies detection. Primary outcome measure: Prevalence (%) and 95% CIs of seropositivity together with adjusted prevalence ratios (aPR) and 95% CI were estimated. Results: A total of 1266 HCWs filled the survey (participation rate: 64.0%) and 1238 underwent serological testing (97.8%). The median age was 43.7 years (p25-p75: 34.8-51.0 years), 76.0% were female, 52.0% were nursing or medical staff and 79.0% worked on-site during the pandemic period. SARS-CoV-2 seroprevalence was 8.9% (95% CI 7.44% to 10.63%), with no differences by age and sex. No significant differences in terms of seroprevalence were observed between onsite workers and teleworkers. Seropositivity was associated with living with a person with COVID-19 (aPR 3.86, 95% CI 2.49 to 5.98). Among on-site workers, seropositive participants were twofold more likely to be nursing or medical staff. Nursing and medical staff working in a COVID-19 area showed a higher seroprevalence than other staff (aPR 2.45, 95% CI 1.08 to 5.52). Conclusions: At the end of the first wave of the pandemic in Spain, SARS-CoV-2 seroprevalence among Institut Català d'Oncologia HCW was lower than the reported in other Spanish hospitals. The main risk factors were sharing household with infected people and contact with COVID-19 patients and colleagues. Strengthening preventive measures and health education among HCW is fundamental.

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.

Participants were men aged 18 years or older, having a negative HIV test result at baseline and agreeing to participate. Bio-behavioural data were collected by peers in each visit. HIV incidence rates using person-time measures and 95% CIs were calculated. Cox logistic regression models were used to identify AFs to seroconversion. Over the period, 3544 participants with at least one follow-up visit or those who had a first visit no longer than a year prior to the date of data censoring were included in the analysis contributing 3567.09 person-year (p-y) and 85 MSM seroconverted for an overall HIV incidence of 2.4 per 100 p-y (95% CI 1.9 to 2.9) ranging from 1.21/100 (2009) to 3.1/100 p-y (2011). Independent AF included: foreign origen, having more than five HIV tests at baseline, reporting in the preceding 6 months the following: condomless anal sex with the last steady partner of unknown serostatus, more than 10 casual partners, condomless anal sex with casual partner, self-reported gonorrhoea and entered in the cohort in 2010 or 2011. The ITACA cohort revealed a high and increasing HIV incidence among MSM, especially important among foreign-born men. The findings underscore the need to implement multilevel interventions for MSM taking into account different types of partners, cultural origens and the exposure to other sexually transmitted infections.

Sexual risk behaviors and some STI have recently increased. Descriptive study of STI diagnosed at the STI Unit of Barcelona between 2001 and 2002. Some STI were more frequent among homosexual men. HIV coinfection in patients with syphilis was seen in 10/18 homosexual men and 1/10 heterosexuals (p = 0.04). There is a resurgence of some STI in Barcelona. New preventive interventions are needed, especially addressed to homosexual men.

Certain subgroups of the immigrant population may be vulnerable to acquiring sexually transmitted infections (STI). Descriptive study of the seroprevalenceof certain STI (HIV, hepatitis B and syphilis) and the general characteristicsn of persons tested for HIV infection in a specialized clinic in Barcelona during the year 2000. Seroprevalence of HIV was similar in immigrants and native residents(1.8% vs. 1.7% respectively). However, the seroprevalences of hepatitis B virus (anti-HBc) (19.5% vs. 8.3%) and syphilis (RPR 1 TPHA) (3.2% vs. 1.1%), as well as other STI and the practice of prostitution, were higher in immigrants. Several STI, including hepatitis B and syphilis, were found more frequently in immigrants than in the native population, whereas HIV seroprevalence was similar in the two groups.
