Abstract
Posttraumatic growth (PTG) among people living with HIV (PLWH) remains an understudied and controversial topic, and several research gaps need to be filled. In our study, we focused on one such gap by implementing parallel assessment of positive (PTG) and negative changes (posttraumatic depreciation [PTD]) following trauma related to HIV diagnosis, along with measurement of resilience and HIV/AIDS stigma and socio-medical data. The study sample comprised 509 PLWH, which completed the standardized psychometric inventories measuring the study variables. The results showed an unexpected positive relationship between PTG and PTD among participants. In addition, following the person-centered approach, we observed specific PTG/PTD clusters in the study sample with different resilience and HIV/AIDS stigma levels. Our study may shed some light on understanding PTG/PTD processes among PLWH and inspire planning for effective psychological help adjusted to patients' specific needs.

Abstract
OBJECTIVES The aim of this study was to analyse patients newly diagnosed with HIV who were originally admitted to hospitals with suspicion of COVID-19. METHODS This was a retrospective case series undertaken at four sites. Only adults with new HIV diagnosis and COVID-19 exclusion hospitalized in 2020-2021 were included. Demographic, clinical and laboratory data were collected from medical records. RESULTS Twenty-five patients were included in the analysis: 19 men (76%), 11 of Ukrainian origin (44%). The median age was 38.5 years (range 25-59). The mode of HIV transmission was heterosexual for 11 (44%) patients, eight (32%) were men who have sex with men and three (12%) were people who inject drugs. The median duration of symptoms prior to hospital presentation was 20.6 days (range 3-90). The median number of SARS-CoV-2 tests per patient was 2.62 (range 1-7). All SARS-CoV-2 tests were negative. Screening for HIV was performed on average on the 18th day of hospitalization (range 1-36 days). Twenty-three patients (92%) were late presenters, 22 (88%) had advanced disease, and 19 (76%) were in the AIDS stage. The median CD4 T-cell count was 72 cells/μL (range 3-382). The rate of positive HIV testing at the two sites where it was available for people with suspected COVID-19 was 0.13% (7/5458 during the study period). CONCLUSIONS We strongly recommend introducing the HIV screening test in the diagnostic algorithm for every patient suspected of having COVID-19, presenting with clinical and/or radiological pulmonary symptoms.

Abstract
INTRODUCTION Delay in HIV diagnosis and consequently late care entry with low CD4 counts remain a major challenge for the control of the HIV/AIDS epidemic. The aim of this study was to analyse the evolution of characteristics of the HIV epidemic in Poland. METHODS Cross-sectional data were collected for 3972 HIV-infected patients followed up in 14 of 17 Polish HIV treatment centres in the years 2000-2015. Clinical data were analysed and factors associated with late presentation (baseline CD4 count < 350 cells/μL or history of AIDS-defining illness) and advanced HIV disease (baseline CD4 count < 200 cells/μL or history of AIDS) were identified. RESULTS The majority (57.6%) of patients entered care late, while 35.6% presented with advanced HIV disease. The odds of being linked to care late or with advanced HIV disease increased consistently across age categories, increasing from 2.55 [95% confidence interval (CI) 1.46-4.47] for late presentation and 3.13 (95% CI 1.49-6.58) for advanced disease for the 21-30-year-old category to 5.2 (95% CI 1.94-14.04) and 8.15 (95% CI 2.88-23.01), respectively, for individuals > 60 years of age. Increased risks of late entry and advanced HIV disease were also observed for injecting drug users [adjusted odds ratio (aOR) 1.74 (95% CI 1.16-2.60) and 1.55 (95% CI 1.05-2.30), respectively], with lower aOR associated with the men who have sex with men transmission route [aOR 0.3 (95% CI 0.31-0.59) and 0.39 (95% CI 0.29-0.53), respectively]. The frequencies of cases in which patients were linked to care late and with advanced HIV disease decreased over time from 67.6% (2000) to 53.5% (2015) (P < 0.0001) and from 43.5% (2000) to 28.4% (2015) (P = 0.001), respectively. CONCLUSIONS Despite improvements over time, most patients diagnosed with HIV infection entered care late, with a third presenting with advanced HIV disease. Late care entry remains common among people who inject drugs and heterosexual groups.

Abstract
HIV-1 env sequencing enables predictions of viral coreceptor tropism and phylogenetic investigations of transmission events. The aim of the study was to estimate the contribution of non-R5 strains to the viral spread in Poland. Partial proviral env sequences were retrieved from baseline blood samples of patients with newly diagnosed HIV-1 infection between 2008-2014, including 46 patients with recent HIV-1 infection (RHI), and 246 individuals with long-term infection (LTHI). These sequences were subjected to the genotypic coreceptor tropism predictions and phylogenetic analyses to identify transmission clusters. Overall, 27 clusters with 57 sequences (19.5%) were detected, including 15 sequences (26.3%) from patients with RHI. The proportion of non-R5 strains among all study participants was 23.3% (68/292), and was comparable between patients with RHI and LTHI (11/46, 23.9% vs 57/246, 23.2%; p = 1.000). All 11 patients with non-R5 strains and RHI were men having sex with men (MSM). Among these patients, 4 had viral sequences grouped within phylogenetic cluster with another sequence of non-R5 strain obtained from patient with LTHI, indicating potential acquisition of non-R5 HIV-1 for at least 4/46 (8.7%) patients with RHI. We were unable to confirm the contribution of patients with RHI to the forward transmission of non-R5 strains, but a relatively high proportion of non-R5 strains among them deserves attention due to the limited susceptibility to CCR5 antagonists.

Abstract
Introduction Early treatment remains the most effective HIV prevention strategy; poor linkage to care after HIV diagnosis may compromise this benefit. We sought to better understand patient characteristics and their association with virological suppression (VS) following cART initiation. Methods The TAK project collects pre-linkage to care and clinical data on patients diagnosed with HIV in voluntary testing facilities in central Poland. Data collected for persons diagnosed in 2010–2013 were linked with HIV clinic records. Individuals linked to care who commenced cART were followed from until the earliest of first VS (HIV RNA < 50 copies/ml), last visit, death or 6 January 2016. Cox-proportional hazard models were used to identify factors associated with first viral suppression. Results 232 persons were HIV positive, 144 (62%, 95% CI 55, 68%) linked to care, 116 (81% of those linked to care, 95% CI 73, 87%) started cART during follow up, of which 113 (97%, 95% CI 93, 99%) achieved VS. Non-PI based regimen (for integrase inhibitors aHR: 5.03: 1.90, 13.32) and HLA B5701-positive (aHR: 3.97: 1.33, 11.85) were associated with higher chance of VS. Unknown syphilis status (aHR: 0.27: 0.13, 0.57) and higher HIV RNA (aHR a tenfold increase: 0.56: 0.42, 0.75) remained associated with lower chance of VS. Conclusions Although a low proportion of persons were linked to care, almost all those linked to care started cART and achieved rapid VS. The high rates of VS were irrespective of prior HIV-associated risk behaviours. Linkage to care remains the highest priority in prevention strategies in central Poland.

Abstract
OBJECTIVES Gender-related factors can influence management decisions, treatment outcomes and the overall long-term wellbeing of people living with HIV (PLWH). The Women Against Viruses in Europe (WAVE) Working Group was established to promote the health and wellbeing of women living with HIV (WLWH). WAVE is part of the European AIDS Clinical Society (EACS) and organizes annual workshops to discuss different issues in the management of WLWH. METHODS In 2016, 34 WAVE members including community representatives, HIV clinicians and researchers met to discuss standards of care for WLWH and to review current guidelines. Participants focused on three different themes: (1) access to and engagement and retention in care; (2) monitoring of women on antiretroviral therapy and management of comorbidities; and (3) review of EACS treatment guidelines. RESULTS Five priority areas for optimizing the care of WLWH were identified: (1) psychosocial aspects of HIV diagnosis and care; (2) mental health and wellbeing; (3) pharmacokinetics, toxicity and tolerability of antiretroviral therapy; (4) coinfections and comorbidities; and (5) sexual and reproductive health. WAVE recommendations are provided for each of these areas, and gaps in knowledge and needs for changes in currently existing standards are discussed. CONCLUSIONS This position statement provides an overview of the key recommendations to optimize the care of WLWH that emerged during the 2016 WAVE workshop.

Abstract
Introduction: Modern combined antiretroviral therapies (cART) allow to effectively suppress HIV-1 viral load, with the 90% virologic success rate, meeting the WHO target in most clinical settings. The aim of this study was to analyse antiretroviral treatment efficacy in Poland and to identify variables associated with virologic suppression. Methods: Cross-sectional data on 5152 (56.92% of the countrywide treated at the time-point of analysis) patients on cART for more than six months with at least one HIV-RNA measurement in 2016 were collected from 14 Polish centres. Patients’ characteristics and treatment type-based outcomes were analysed for the virologic suppression thresholds of <50 and <200 HIV-RNA copies/ml. CART was categorized into two nucleos(t)ide (2NRTI) plus non-nucleoside reverse transcriptase (NNRTI) inhibitors, 2NRTI plus protease (PI) inhibitor, 2NRTI plus integrase (InI) inhibitor, nucleos(t)ide sparing PI/r+InI and three drug class regimens. For statistics Chi-square and U-Mann Whitney tests and adjusted multivariate logistic regression models were used. Results: Virologic suppression rates of <50 copies/mL were observed in 4672 (90.68%) and <200 copies/mL in 4934 (95.77%) individuals. In univariate analyses, for the suppression threshold <50 copies/mL higher efficacy was noted for 2NRTI+NNRTI-based combinations (94.73%) compared to 2NRTI+PI (89.93%), 2NRTI+InI (90.61%), nucleos(t)ide sparing PI/r+InI (82.02%) and three drug class regimens (74.49%) (p < 0.0001), with less pronounced but significant differences for the threshold of 200 copies/mL [2NRTI+NNRTI-97.61%, 2NRTI+PI-95.27%, 2NRTI+InI-96.61%, PI/r+InI- 95.51% and 86.22% for three drug class cART) (p < 0.0001). However, in multivariate model, virologic efficacy for viral load <50 copies/mL was similar across treatment groups with significant influence by history of AIDS [OR:1.48 (95%CI:1.01–2.17) if AIDS diagnosed, p = 0.046], viral load < 5 log copies/mL at care entry [OR:1.47 (95%CI:1.08–2.01), p = 0.016], baseline lymphocyte CD4 count ≥200 cells/µL [OR:1.72 (95%CI:1.04–2.78), p = 0.034] and negative HCV serology [OR:1.97 (95%CI:1.29–2.94), p = 0.002]. For viral load threshold <200 copies/mL higher likelihood of virologic success was only associated with baseline lymphocyte CD4 count ≥200 cells/µL [OR:2.08 (95%CI:1.01–4.35), p = 0.049] and negative HCV status [OR:2.84 (95%CI:1.52–5.26), p = 0.001]. Conclusions: Proportion of virologically suppressed patients is in line with WHO treatment target confirming successful application of antiretroviral treatment strategy in Poland. Virological suppression rates depend on baseline patient characteristics, which should guide individualized antiretroviral tre0atment decisions.

Abstract
INTRODUCTION Reconstruction of HIV transmission links allows to trace the spread and dynamics of infection and guide epidemiological interventions. The aim of this study was to characterize transmission networks among subtype B infected patients from Poland. MATERIAL AND METHODS Maximum likelihood phylogenenetic trees were inferred from 966 HIV-1 subtype B protease/reverse transcriptase sequences from patients followed up in nine Polish HIV centers. Monophyletic clusters were identified using 3% within-cluster distance and 0.9 bootstrap values. Interregional links for the clusters were investigated and time from infection to onward transmission estimated using Bayesian dated MCMC phylogeny. RESULTS Three hundred twenty one (33.2%) sequences formed 109 clusters, including ten clusters of ≥5 sequences (n = 81, 8.4%). Transmission networks were more common among MSM (234 sequences, 68.6%) compared to other infection routes (injection drug use: 28 (8.2%) and heterosexual transmissions: 59 (17.3%) cases, respectively [OR:3.5 (95%CI:2.6-4.6),p<0.001]. Frequency of clustering increased from 26.92% in 2009 to 50.6% in 2014 [OR:1.18 (95%CI:1.06-1.31),p = 0.0026; slope +2.8%/year] with median time to onward transmission within clusters of 1.38 (IQR:0.59-2.52) years. In multivariate models clustering was associated with both MSM transmission route [OR:2.24 (95%CI:1.38-3.65),p<0.001] and asymptomatic stage of HIV infection [OR:1.93 (95%CI:1.4-2.64),p<0.0001]. Additionally, interregional networks were linked to MSM transmissions [OR:4.7 (95%CI:2.55-8.96),p<0.001]. CONCLUSIONS Reconstruction of the HIV-1 subtype B transmission patterns reveals increasing degree of clustering and existence of interregional networks among Polish MSM. Dated phylogeny confirms the association between onward transmission and recent infections. High transmission dynamics among Polish MSM emphasizes the necessity for active testing and early treatment in this group.
