AIMS: We measured the association between a history of incarceration and HIV positivity among people who inject drugs (PWID) across Europe. DESIGN, SETTING AND PARTICIPANTS: This was a cross-sectional, multi-site, multi-year propensity-score matched analysis conducted in Europe. Participants comprised community-recruited PWID who reported a recent injection (within the last 12 months). MEASUREMENTS: Data on incarceration history, demographics, substance use, sexual behavior and harm reduction service use originated from cross-sectional studies among PWID in Europe. Our primary outcome was HIV status. Generalized linear mixed models and propensity-score matching were used to compare HIV status between ever- and never-incarcerated PWID. FINDINGS: Among 43 807 PWID from 82 studies surveyed (in 22 sites and 13 countries), 58.7% reported having ever been in prison and 7.16% (n = 3099) tested HIV-positive. Incarceration was associated with 30% higher odds of HIV infection [adjusted odds ratio (aOR) = 1.32, 95% confidence interval (CI) = 1.09-1.59]; the association between a history of incarceration and HIV infection was strongest among PWID, with the lowest estimated propensity-score for having a history of incarceration (aOR = 1.78, 95% CI = 1.47-2.16). Additionally, mainly injecting cocaine and/or opioids (aOR = 2.16, 95% CI = 1.33-3.53), increased duration of injecting drugs (per 8 years aOR = 1.31, 95% CI = 1.16-1.48), ever sharing needles/syringes (aOR = 1.91, 95% CI = 1.59-2.28) and increased income inequality among the general population (measured by the Gini index, aOR = 1.34, 95% CI = 1.18-1.51) were associated with a higher odds of HIV infection. Older age (per 8 years aOR = 0.84, 95% CI = 0.76-0.94), male sex (aOR = 0.77, 95% CI = 0.65-0.91) and reporting pharmacies as the main source of clean syringes (aOR = 0.72, 95% CI = 0.59-0.88) were associated with lower odds of HIV positivity. CONCLUSIONS: A history of incarceration appears to be independently associated with HIV infection among people who inject drugs (PWID) in Europe, with a stronger effect among PWID with lower probability of incarceration.

BACKGROUND: HIV-positive men who have sex with men (MSM) are more likely to experience human papillomavirus (HPV) infection. The persistent HPV infection is the major factor in the development of anal and oropharyngeal neoplasms. Data on the prevalence of anal and oral HPV in MSM are almost absent from the countries of Central and Eastern Europe. We conducted a cross-sectional study focused on the prevalence of oral and anal HPV infections and the relationship between current anal and oral HPV intrapersonal infection in a Czech population of predominantly HIV-positive MSM. METHODS: Oral gargle and anal swab samples from 205 predominantly HIV-positive MSM from the Czech Republic were analysed for HPV infection using PCR. Selected sociodemographic and clinical data were correlated with HPV detection using generalized linear models and multivariate analysis. RESULTS: HPV infection was detected in 183 (96.8%) anal and 48 (23.6%) oral samples. The most common type of HR-HPV was HPV16 in both anal (25.4%) and oral (2.5%) samples. Multiple anal HPV infections and the presence of vaccine-targeted HR-HPV types were significantly correlated with abnormal anal cytology and HIV status. CONCLUSION: The prevalence of anal HPV infection in Czech predominantly HIV-positive MSM ranks among the highest reported, while oral HPV prevalence is consistent with MSM populations. Minimal overlap of oral and anal HPV types within a patient was observed.

OBJECTIVES: The aim of this international multicentre study was to review potential drug-drug interactions (DDIs) for real-life coadministration of combination antiretroviral therapy (cART) and coronavirus disease 2019 (COVID-19)-specific medications. METHODS: The Euroguidelines in Central and Eastern Europe Network Group initiated a retrospective, observational cohort study of HIV-positive patients diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Data were collected through a standardized questionnaire and DDIs were identified using the University of Liverpool's interaction checker. RESULTS: In total, 524 (94.1% of 557) patients received cART at COVID-19 onset: 117 (22.3%) were female, and the median age was 42 (interquartile range 36-50) years. Only 115 (21.9%) patients were hospitalized, of whom 34 required oxygen therapy. The most frequent nucleoside reverse transcriptase inhibitor (NRTI) backbone was tenofovir disoproxil fumarate (TDF)/tenofovir alafenamide (TAF) with lamivudine or emtricitabine (XTC) (79.3%) along with an integrase strand transfer inhibitor (INSTI) (68.5%), nonnucleoside reverse transcriptase inhibitor (NNRTI) (17.7%), protease inhibitor (PI) (13.7%) or other (2.5%). In total, 148 (28.2%) patients received COVID-19-specific treatments: corticosteroids (15.7%), favipiravir (7.1%), remdesivir (3.1%), hydroxychloroquine (2.7%), tocilizumab (0.6%) and anakinra (0.2%). In total, 62 DDI episodes were identified in 58 patients (11.8% of the total cohort and 41.9% of the COVID-19-specific treatment group). The use of boosted PIs and elvitegravir accounted for 43 DDIs (29%), whereas NNRTIs were responsible for 14 DDIs (9.5%). CONCLUSIONS: In this analysis from the Central and Eastern European region on HIV-positive persons receiving COVID-19-specific treatment, it was found that potential DDIs were common. Although low-dose steroids are mainly used for COVID-19 treatment, comedication with boosted antiretrovirals seems to have the most frequent potential for DDIs. In addition, attention should be paid to NNRTI coadministration.

BACKGROUND: Cervical cancer screening might contribute to the prevention of anal cancer in women. We aimed to investigate if routine cervical cancer screening results-namely high-risk human papillomavirus (HPV) infection and cytohistopathology-predict anal HPV16 infection, anal high-grade squamous intraepithelial lesions (HSIL) and, hence, anal cancer. METHODS: We did a systematic review of MEDLINE, Embase, and the Cochrane library for studies of cervical determinants of anal HPV and HSIL published up to Aug 31, 2018. We centrally reanalysed individual-level data from 13 427 women with paired cervical and anal samples from 36 studies. We compared anal high-risk HPV prevalence by HIV status, cervical high-risk HPV, cervical cytohistopathology, age, and their combinations, using prevalence ratios (PR) and 95% CIs. Among 3255 women with anal cytohistopathology results, PRs were similarly calculated for all anal HSIL and HPV16-positive anal HSIL. FINDINGS: Cervical and anal HPV infections were highly correlated. In HIV-negative women, anal HPV16 prevalence was 41% (447/1097) in cervical HPV16-positive versus 2% (214/8663) in cervical HPV16-negative women (PR 16·5, 95% CI 14·2-19·2, p<0·0001); these values were 46% (125/273) versus 11% (272/2588) in HIV-positive women (4·4, 3·7-5·3, p<0·0001). Anal HPV16 was also associated with cervical cytohistopathology, with a prevalence of 44% [101/228] for cervical cancer in HIV-negative women (PR vs normal cytology 14·1, 11·1-17·9, p<0·0001). Anal HSIL was associated with cervical high-risk HPV, both in HIV-negative women (from 2% [11/527] in cervical high-risk HPV-negative women up to 24% [33/138] in cervical HPV16-positive women; PR 12·9, 95% CI 6·7-24·8, p<0·0001) and HIV-positive women (from 8% [84/1094] to 17% [31/186]; 2·3, 1·6-3·4, p<0·0001). Anal HSIL was also associated with cervical cytohistopathology, both in HIV-negative women (from 1% [5/498] in normal cytology up to 22% [59/273] in cervical HSIL; PR 23·1, 9·4-57·0, p<0·0001) and HIV-positive women (from 7% [105/1421] to 25% [25/101]; 3·6, 2·5-5·3, p<0·0001). Prevalence of HPV16-positive anal HSIL was 23-25% in cervical HPV16-positive women older than 45 years (5/20 in HIV-negative women, 12/52 in HIV-positive women). INTERPRETATION: HPV-based cervical cancer screening programmes might help to stratify anal cancer risk, irrespective of HIV status. For targeted secondary anal cancer prevention in high-risk groups, HIV-negative women with cervical HPV16, especially those older than 45 years, have a similar anal cancer risk profile to that of HIV-positive women.

Peptide immunogens provide an approach to focus antibody responses to specific neutralizing sites on the HIV envelope protein (Env) trimer or on other pathogens. However, the physical characteristics of peptide immunogens can limit their pharmacokinetic and immunological properties. Here, we have designed synthetic "star" nanoparticles based on biocompatible N-[(2-hydroxypropyl)methacrylamide] (HPMA)-based polymer arms extending from a poly(amidoamine) (PAMAM) dendrimer core. In mice, these star nanoparticles trafficked to lymph nodes (LNs) by 4 hours following vaccination, where they were taken up by subcapsular macrophages and then resident dendritic cells (DCs). Immunogenicity optimization studies revealed a correlation of immunogen density with antibody titers. Furthermore, the co-delivery of Env variable loop 3 (V3) and T-helper peptides induced titers that were 2 logs higher than if the peptides were given in separate nanoparticles. Finally, we performed a nonhuman primate (NHP) study using a V3 glycopeptide minimal immunogen that was structurally optimized to be recognized by Env V3/glycan broadly neutralizing antibodies (bnAbs). When administered with a potent Toll-like receptor (TLR) 7/8 agonist adjuvant, these nanoparticles elicited high antibody binding titers to the V3 site. Similar to human V3/glycan bnAbs, certain monoclonal antibodies (mAbs) elicited by this vaccine were glycan dependent or targeted the GDIR peptide motif. To improve affinity to native Env trimer affinity, nonhuman primates (NHPs) were boosted with various SOSIP Env proteins; however, significant neutralization was not observed. Taken together, this study provides a new vaccine platform for administration of glycopeptide immunogens for focusing immune responses to specific bnAb epitopes.

OBJECTIVE: Men who have sex with men (MSM) are disproportionately affected by HIV in Greece. However, research on HIV incidence in this group is lacking. This study aimed at estimating HIV incidence among MSM in Athens, Greece. METHODS: The analysis included routinely collected data between January 2013-June 2015 from adult MSM who visited a community-based facility (Ath Checkpoint) at least twice and were non-reactive to the rapid INSTITM HIV-1/HIV-2 assay at baseline. HIV conversion rates were calculated by dividing the number of clients who became reactive by the person-years of observation. All statistical analyses including Poisson regression models were conducted in STATA 14. RESULTS: A total of 1,243 MSM contributed 1,102.50 person-years (py). The overall (per 100 py) conversion rate was 3.99 (95% CI: 2.97-5.36). In multivariable analyses, age less than 30 years was associated with an increased risk of HIV conversion (rate ratio: 2.01; 95% CI: 1.08-3.76). CONCLUSIONS: This analysis shows high rates of HIV conversion among MSM who repeatedly visit a community-based testing site. Ath Checkpoint could contribute to HIV surveillance and identify a high-risk group that could benefit from essential health interventions.

We describe the first case of chancroid seen in the Czech Republic, diagnosed in a 40-year-old heterosexual HIV-positive man. Despite genital localization of the ulcer, the transmission of Haemophilus ducreyi infection in our patient remains unclear, as he denied having sexual intercourse and he did not travel outside the Czech Republic for several months before the ulcer appeared. The correct diagnosis has been revealed by a multiplex nucleic acid amplification test. Physicians in countries in the eastern and central Europe region should be aware that chancroid can occur in their patients.

BACKGROUND: Randomized trials have shown increased risk of suicidality associated with efavirenz (EFV). The START (Strategic Timing of Antiretroviral Treatment) trial randomized treatment-naive human immunodeficiency virus (HIV)-positive adults with high CD4 cell counts to immediate vs deferred antiretroviral therapy (ART). METHODS: The initial ART regimen was selected prior to randomization (prespecified). We compared the incidence of suicidal and self-injurious behaviours (suicidal behavior) between the immediate vs deferred ART groups using proportional hazards models, separately for those with EFV and other prespecified regimens, by intention to treat, and after censoring participants in the deferred arm at ART initiation. RESULTS: Of 4684 participants, 271 (5.8%) had a prior psychiatric diagnosis. EFV was prespecified for 3515 participants (75%), less often in those with psychiatric diagnoses (40%) than without (77%). While the overall intention-to-treat comparison showed no difference in suicidal behavior between arms (hazard ratio [HR], 1.07, P = .81), subgroup analyses suggest that initiation of EFV, but not other ART, is associated with increased risk of suicidal behavior. When censoring follow-up at ART initiation in the deferred group, the immediate vs deferred HR among those who were prespecified EFV was 3.31 (P = .03) and 1.04 (P = .93) among those with other prespecified ART; (P = .07 for interaction). In the immediate group, the risk was higher among those with prior psychiatric diagnoses, regardless of prespecified treatment group. CONCLUSIONS: Participants who used EFV in the immediate ART group had increased risk of suicidal behavior compared with ART-naive controls. Those with prior psychiatric diagnoses were at higher risk.

Centers for Disease Control and Prevention and sequencing-based treponeme typing was used to analyze 72 blood samples, collected from human immunodeficiency virus and syphilis co-infected patients during 2014 to 2015 in Antwerp, Belgium. Twenty-nine (40.3%) isolates were polymerase chain reaction positive for Treponema pallidum, and all tested were macrolide-resistant. Four genotypes were identified by sequencing-based typing including two new genotypes, U4NR8 and SU9R8, whereas enhanced Centers for Disease Control and Prevention typing revealed 7 subtypes.

The HIV infection remains a major public health issue in the world and especially in those countries where there exists unprotected sexual intercourse between people of the same sex. It is namely the category of men having sex with men (MSM) that still represents a group at high risk of being infected with HIV or transmitting the virus. The aim of our study was to present HIV 2nd generation surveillance data on MSM in Slovakia in the period between the years 2008 and 2009. Time-location sampling (TLS) was used to recruit participants and oral fluid samples together with completed anonymous questionnaires were collected simultaneously. The oral fluids were tested with use of the Genscreen HIV ½ version 2, (Bio-Rad) and Western Blot (Genlabs) diagnostic kits. The data analysis was performed using Stata version 8. Saliva testing revealed HIV prevalence of 6.1% (21/349) among MSM in Slovakia. 75% of HIV-positive cases were undiagnosed. The high-risk behaviour of MSM in respect to the number of their sexual partners as well as drug and condom usage did not correspond with their relatively high knowledge about HIV/AIDS. People's attitude towards MSM was found to be the worst in the religious context. Though our results reflect a relative good knowledge of MSM about HIV/AIDS infection, new HIV-positive cases and high-risk behaviour still appear, suggesting the need for more effective HIV prevention among members of this high-risk group in Slovakia.
