Clinical Perspective on Human Immunodeficiency Virus Care of Ukrainian War Refugees in Poland. Clin Infect Dis 2023; 76:1708-1715. [PMID: 36888680 DOI: 10.1093/cid/ciad116] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 01/23/2023] [Accepted: 02/28/2023] [Indexed: 03/09/2023] Open
Abstract
BACKGROUND The Russian invasion of Ukraine forced migration for safety, protection, and assistance. Poland is the primary sheltering country for Ukrainian refugees, providing support including medical care, which resulted in the rapid ∼15% increase in the number of followed-up people with human immunodeficiency virus (HIV) (PWH) in the country. Here, we present the national experience on HIV care provided for refugees from Ukraine. METHODS Clinical, antiretroviral, immunological, and virologic data from 955 Ukrainian PWH entering care in Poland since February 2022 were analyzed. The dataset included both antiretroviral-treated (n = 851) and newly diagnosed (n = 104) patients. In 76 cases, protease/reverse transcriptase/integrase sequencing was performed to identify drug resistance and subtype. RESULTS Most (70.05%) of the patients were female, with a predominance of heterosexual (70.3%) transmissions. Anti-hepatitis C antibody and hepatitis B antigen were present in 28.7% and 2.9% of the patients, respectively. A history of tuberculosis was reported in 10.1% of cases. Among previously treated patients, the viral suppression rate was 89.6%; 77.3% of newly HIV diagnosed cases were diagnosed late (with lymphocyte CD4 count <350 cells/μL or AIDS). The A6 variant was observed in 89.0% of sequences. Transmitted mutations in the reverse transcriptase were found in 15.4% treatment-naive cases. Two patients with treatment failure exhibited multiclass drug resistance. CONCLUSIONS Migration from Ukraine influences the characteristics of HIV epidemics in Europe, with an increase in the proportion of women and hepatitis C coinfected patients. Antiretroviral treatment efficacy among previously treated refugees was high, with new HIV cases frequently diagnosed late. The A6 subtype was the most common variant.

Clinical parameters, selected HLA and chemokine gene variants associated with late presentation into care of people living with HIV/AIDS. INFECTION, GENETICS AND EVOLUTION : JOURNAL OF MOLECULAR EPIDEMIOLOGY AND EVOLUTIONARY GENETICS IN INFECTIOUS DISEASES 2022; 97:105180. [PMID: 34896288 DOI: 10.1016/j.meegid.2021.105180] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/28/2021] [Revised: 10/05/2021] [Accepted: 12/06/2021] [Indexed: 11/29/2022]
Abstract
INTRODUCTION Late presentation into care remains a significant problem in the diagnosis of HIV infection, and may negatively impact the Joint United Nations Program HIV/AIDS elimination targets. Host genetics affects the tempo of HIV disease progression and therefore may influence clinical status at care entry. MATERIALS AND METHODS Longitudinal data were collected for 863 Caucasian patients followed up at Pomeranian Medical University, Szczecin, Poland. Single nucleotide polymorphisms in CCR2 (rs1799864), CX3CR1 (rs3732378), HLAC-35 (rs9264942), CCR5 promoter (rs1799988) as well as 32 base pair CCR5 mutation and HLA-B*5701 genotypes were correlated with the clinical and immunologic patient status at care entry. Late presentation was defined as baseline CD4 lymphocyte count <350 cells/μL or history of AIDS-defining illness, while advanced HIV disease as baseline CD4 lymphocyte count <200 cells/μL or AIDS. RESULTS Of the analyzed gene variants, the CCR2 (rs1799864) GG genotype was more frequent among patients presenting for care with a CD4 lymphocyte count <200/μL (82.6% for GG homozygotes vs. 74.5% for allele A carriers, p = 0.01). The presence of the heterozygous wt/Δ32 genotype at the CCR5 gene was associated with a higher frequency of asymptomatic infection (18.9% for wt/Δ32 heterozygotes vs. 12% for wt/wt homozygotes, p = 0.03). As expected, this association was also observed among late presenters compared to patients presenting for care earlier (13.7% vs. 19,7%, respectively, p = 0.04). Finally, HLA-B*5701 was less common among late presenters (5%) compared to patients who entered care early (9.6%, p = 0.01) or patients with advanced HIV disease (8.9% vs. 5.2%, p = 0.02). CONCLUSIONS Late presentation was associated with the GG homozygous genotype at the CCR2 rs1799864 SNP, while both the HLA-B*5701 variant and the CCR5 wt/Δ32 were associated with more favorable clinical profile at care entry.

Long-term trends in HIV care entry: over 15 years of clinical experience from Poland. HIV Med 2019; 20:581-590. [PMID: 31250958 DOI: 10.1111/hiv.12762] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/03/2019] [Indexed: 01/12/2023]
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.

Hepatitis C coinfection adversely affects the life expectancy of people living with HIV in northwestern Poland. Arch Med Sci 2018; 14:554-559. [PMID: 29765442 PMCID: PMC5949897 DOI: 10.5114/aoms.2016.58744] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2015] [Accepted: 02/01/2016] [Indexed: 12/26/2022] Open
Abstract
INTRODUCTION Hepatitis C (HCV) infection adversely affects survival among people living with HIV, increasing mortality risk due to liver-related causes. In Poland HCV is found among ~30% of HIV infected individuals, with only a small percentage successfully treated for this coinfection. This study aimed to analyze the HCV-associated influence on the life expectancy among HIV/HCV coinfected patients from northwestern Poland. MATERIAL AND METHODS Longitudinal data of 701 (368 HIV monoinfected and 368 HIV/HCV coinfected) patients were investigated to assess the life expectancy and survival after HIV diagnosis. Kaplan-Meier and Cox analyses were used to assess the mortality risk in both unadjusted and multivariate models. Effect plots indicate the adjusted hazard ratio for HCV-associated survival. RESULTS Overall mortality was significantly higher among HCV coinfected (22.52%) compared to HIV monoinfected (10.32%) cases (p < 0.001, OR = 2.52 (95% CI: 1.65-3.85)), with shorter life expectancy among HIV/HCV infected patients (median: 55.4 (IQR: 42.8-59.1) years) compared to HIV monoinfection (median 72.7 (IQR: 60.4-76.8) years, univariate HR = 4.15 (95% CI: 2.7-6.38), p < 0.0001, adjusted HR = 2.32 (95% CI: 1.47-3.65), p < 0.0001). After HIV diagnosis, HCV adversely influenced the survival after 15 years of follow-up, with a strengthened impact in the subsequent 5 years (univariate HR = 1.57 (95% CI: 1.05-2.34) p = 0.026 for the 20-year survival time point, adjusted HR = 2.21 (95% CI: 1.18-4.13), p = 0.013). CONCLUSIONS Among patients living with HIV, HCV coinfection is associated with a median life expectancy decrease of 17.3 years and low probability of surviving until the age of 65 years. In the era of directly acting anti-HCV drugs, treatment scale-up and immediacy of treatment are advisable in this cohort.

Hypertension, dyslipidaemia, and cardiovascular risk in HIV-infected adults in Poland. Kardiol Pol 2017; 75:1324-1331. [PMID: 28715065 DOI: 10.5603/kp.a2017.0148] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2017] [Revised: 05/30/2017] [Accepted: 07/06/2017] [Indexed: 11/25/2022]
Abstract
BACKGROUND The prevalence of cardiovascular diseases (CVD) in HIV-infected patients increases with aging and duration of the disease. Hypertension, high cholesterol level obesity, diabetes, tobacco exposure, and use of alcohol are among the traditional risk factors that contribute to CVD. AIM The aim of the study was to determinate the incidence of hypertension, lipid disturbances, and CVD risk in dependence on clinical, viral, and biochemical factors. METHODS A total of 417 HIV-infected Caucasian adult patients from the four clinical centres in Poland were enrolled and analysed on the basis of available medical data from the years 2013-2015. RESULTS Hypertension was diagnosed in 28% of all patients and in the age ranges: < 40 years, 41-60 years and > 60 years in 18%, 43%, and 53%, respectively. The percentage of optimal, normal, and high normal blood pressure was: 28%, 14%, and 30%, respectively. Hypertension grade 1, 2, and 3 was observed in 58%, 35%, and 7% of patients, respectively. Factors associated with hypertension were: increasing age, male sex, increased body mass index, hypercholesterolaemia, hypo-high density lipoprotein (HDL), hypertriglyceridaemia and duration of HIV infection more than 10 years. Hypercholesterolaemia, suboptimal level of HDL, elevated low-density lipoprotein, and hypertriglyceridaemia were observed in 37%, 20.5%, 31%, and 52%, respectively. Hypertriglyceridaemia was associated with protease inhibitor-based highly active antiretroviral therapy. HCV infection was negatively associated with hypercholesterolaemia. Cigarette smoking was reported in 55% of cases. CONCLUSIONS Incidence of hypertension in particular age groups of HIV infected people is higher than in the general Polish population. Hypertension is influenced by traditional risk factors and duration of HIV infection but not antiretroviral treatment. HIV/HCV coinfection appears to be protective against hypercholesterolaemia.

Expanding HIV-1 subtype B transmission networks among men who have sex with men in Poland. PLoS One 2017; 12:e0172473. [PMID: 28234955 PMCID: PMC5325290 DOI: 10.1371/journal.pone.0172473] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2016] [Accepted: 02/05/2017] [Indexed: 12/17/2022] Open
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.

Differences in the integrase and reverse transcriptase transmitted resistance patterns in Northern Poland. INFECTION GENETICS AND EVOLUTION 2016; 49:122-129. [PMID: 28017912 DOI: 10.1016/j.meegid.2016.12.019] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/10/2016] [Revised: 12/15/2016] [Accepted: 12/21/2016] [Indexed: 02/08/2023]
Abstract
INTRODUCTION With the widespread introduction of the integrase (In) inhibitors into clinical practice, transmission of drug resistance to this class of antiretroviral medications may expand. The aim of this study was to analyze the recent patterns of In resistance in treatment naive individuals in Northern Poland and its association with transmitted protease (PR) and reverse transcriptase (RT) mutations. METHODS Study included 172 PR, RT and InI sequences from antiretroviral treatment naive HIV-1 infected patients linked to care in Northern Poland from 2010 to 2015. Drug resistance was interpreted based on the WHO surveillance and IAS-USA mutation lists. For phylogeny maximum likelihood and Bayesian Monte Carlo Markov Chain analyses were used. RESULTS Overall rate of transmitted drug resistance was 12.21%. Nucleoside reverse transcriptase inhibitor (NRTI) resistance associated substitutions were found in 11.05% of cases and non-nucleoside reverse transcriptase inhibitor resistance variants in 1.16%. In multivariate models transmitted resistance strongly associated with subtype D infections [66.67% compared to the 3.84% for subtype B (p=0.001)]. No transmission of major protease or integrase mutations were observed. Polymorphisms associated with resistance against integrase inhibitor, mostly E157Q, were found in 21.5% sequences and associated with female (31.91% vs. 15.2% for male, p=0.01), injection drug use (84.21% compared to 22.08% for heterosexual and 1.39% for men-who-have-sex-with-men transmissions, p<0.0001) as well as hepatitis C coinfection [63.64% for positive, versus 8.57% for HCV antibody negative, p<0.0001]. Clusters of nucleoside reverse transcriptase mutations in subtype D and integrase E157Q variants in subtype B were observed. CONCLUSIONS Transmitted drug resistance frequency was high in subtype D but limited to clustered NRTI mutations, being infrequent among subtype B infected cases. Despite lack of major integrase resistance in treatment naive patients, variants potentially affecting susceptibility to this class were common, which indicates the potential need for extended surveillance in the near future.

Distribution and time trends of HIV-1 variants in Poland: Characteristics of non-B clades and recombinant viruses. INFECTION GENETICS AND EVOLUTION 2016; 39:232-240. [PMID: 26851192 DOI: 10.1016/j.meegid.2016.02.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2015] [Revised: 01/28/2016] [Accepted: 02/01/2016] [Indexed: 02/02/2023]
Abstract
The spread of HIV-1 subtypes varies considerably both worldwide and within Europe, with non-B variants commonly found across various exposure groups. This study aimed to analyse the distribution and temporal trends in HIV-1 subtype variability across Poland. For analysis of the subtype distribution, 1219 partial pol sequences obtained from patients followed up in 9 of 17 Polish HIV treatment centres were used. Subtyping was inferred using the maximum likelihood method; recombination was assessed using the bootscanning and jumping profile hidden Markov model methods. Subtype B dominated in the studied group (n=1059, 86.9%); in 160 (13.1%) sequences, non-B variants were present [A1 (n=63, 5.2%), D (n=43, 3.5%), C (n=22, 1.8%), and F1 (n=2, 0.2%)]. In 25 (2.1%) cases circulating recombinant forms (CRFs) were found. Five A1 variants (0.4%) were unique AB recombinant forms (URF) not previously identified in Poland. Non-B clades were notably more common among females (n=73, 45.6%, p<0.001) and heterosexual individuals (n=103, 66.5%, p<0.001) and less frequent among men who have sex with men (MSM) (n=27, 17.42%, p<0.001). HIV-1 viral load at diagnosis was higher among non-B cases [median: 5.0 (IQR: 4.4-5.6)] vs. [median: 4.8 (IQR: 4.3-5.4) log copies/ml for subtype B (p<0.001)] with a lower CD4(+) lymphocyte count at baseline [median: 248 (IQR: 75-503) for non-B vs. median: 320 (IQR: 125-497) cells/μl for subtype B; p<0.001]. The frequency of the non-B subtypes proved stable from 2008 (11.5%) to 2014 (8.0%) [OR: 0.95 (95% CI: 0.84-1.07), p=0.4], with no temporal differences for exposure groups, gender, age and AIDS. Despite the predominance of subtype B, the variability of HIV in Poland is notable; both CRFs and URFs are present in the analysed population. Non-B variants are associated with heterosexual transmission, more advanced HIV disease and have stable temporal frequencies.

Transmission of HIV Drug Resistance and the Predicted Effect on Current First-line Regimens in Europe. Clin Infect Dis 2015; 62:655-663.

Abstract
Transmitted human immunodeficiency virus drug resistance in Europe is stable at around 8%. The impact of baseline mutation patterns on susceptibility to antiretroviral drugs should be addressed using clinical guidelines. The impact on baseline susceptibility is largest for nonnucleoside reverse transcriptase inhibitors. Background. Numerous studies have shown that baseline drug resistance patterns may influence the outcome of antiretroviral therapy. Therefore, guidelines recommend drug resistance testing to guide the choice of initial regimen. In addition to optimizing individual patient management, these baseline resistance data enable transmitted drug resistance (TDR) to be surveyed for public health purposes. The SPREAD program systematically collects data to gain insight into TDR occurring in Europe since 2001. Methods. Demographic, clinical, and virological data from 4140 antiretroviral-naive human immunodeficiency virus (HIV)–infected individuals from 26 countries who were newly diagnosed between 2008 and 2010 were analyzed. Evidence of TDR was defined using the WHO list for surveillance of drug resistance mutations. Prevalence of TDR was assessed over time by comparing the results to SPREAD data from 2002 to 2007. Baseline susceptibility to antiretroviral drugs was predicted using the Stanford HIVdb program version 7.0. Results. The overall prevalence of TDR did not change significantly over time and was 8.3% (95% confidence interval, 7.2%–9.5%) in 2008–2010. The most frequent indicators of TDR were nucleoside reverse transcriptase inhibitor (NRTI) mutations (4.5%), followed by nonnucleoside reverse transcriptase inhibitor (NNRTI) mutations (2.9%) and protease inhibitor mutations (2.0%). Baseline mutations were most predictive of reduced susceptibility to initial NNRTI-based regimens: 4.5% and 6.5% of patient isolates were predicted to have resistance to regimens containing efavirenz or rilpivirine, respectively, independent of current NRTI backbones. Conclusions. Although TDR was highest for NRTIs, the impact of baseline drug resistance patterns on susceptibility was largest for NNRTIs. The prevalence of TDR assessed by epidemiological surveys does not clearly indicate to what degree susceptibility to different drug classes is affected.

The Spectrum of Malignancies among Adult HIV Cohort in Poland between 1995 and 2012: A Retrospective Analysis of 288 Cases. Contemp Oncol (Pozn) 2015; 19:226-35. [PMID: 26557764 PMCID: PMC4631280 DOI: 10.5114/wo.2015.52658] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2014] [Revised: 01/05/2015] [Accepted: 03/20/2015] [Indexed: 01/09/2023] Open
Abstract
THE AIM OF THE STUDY The aim of the study was to evaluate the spectrum of AIDS-defining malignancies (ADMs) and non-AIDS-defining malignancies (NADMs) in HIV-infected patients in Poland. MATERIAL AND METHODS A retrospective observational study was conducted among HIV-infected adult patients who developed a malignancy between 1995 and 2012 in a Polish cohort. Malignancies were divided into ADMs and NADMs. Non-AIDS-defining malignancies were further categorised as virus-related (NADMs-VR) and unrelated (NADMs-VUR). Epidemiological data was analysed according to demographic data, medical history, and HIV-related information. Results were analysed by OR, EPITools package parameters and Fisher's exact test. RESULTS In this study 288 malignancies were discovered. The mean age at diagnosis was 41.25 years (IQR20-81); for ADMs 38.05 years, and for NADMs-VURs 46.42 years; 72.22% were male, 40.28% were co-infected with HCV. The risk behaviours were: 37.85% IDU, 33.33% MSM, and 24.31% heterosexual. Mean CD4+ at the diagnosis was 282 cells/mm(3) (for ADMs 232 and for NADMs-VUR 395). Average duration of HIV infection at diagnosis was 5.69 years. There were 159 (55.2%) ADMs and 129 (44.8%) NADMs, among whom 58 (44.96%) NADMs-VR and 71 (55.04%) NADMs-VUR. The most frequent malignancies were: NHL (n = 76; 26.39%), KS (n = 49; 17.01%), ICC (n = 34; 11.81%), HD (n = 23; 7.99%), lung cancer (n = 18; 6.25%) and HCC (n = 14; 4.86%). The amount of NADMs, NADMs-VURs in particular, is increasing at present. Male gender (OR = 1.889; 95% CI: 1.104-3.233; p = 0.024), advanced age: 50-60 years (OR = 3.022; 95% CI: 1.359-6.720; p = 0.01) and ≥ 60 years (OR = 15.111; 95% CI: 3.122-73.151; p < 0.001), longer duration of HIV-infection and successful HAART (OR = 2.769; 95% CI: 1.675-4.577; p = 0) were independent predictors of NADMs overall, respectively. CONCLUSIONS In a Polish cohort NHL was the most frequent malignancy among ADMs, whereas HD was the most frequent among NADMs. Increased incidence of NADMs appearing in elderly men with longer duration of HIV-infection and with better virological and immunological control was confirmed. As HIV-infected individuals live longer, better screening strategies, especially for NADMs-VUR, are needed. The spectrum of cancer diagnoses in Poland currently does not appear dissimilar to that observed in other European populations.

Abstract
We analyzed occupational exposure to potentially infectious body fluids among health care workers (HCWs). Nurses were the most common exposed category of HCWs. In 73.6% cases needle sticks had been the reason of exposure. Recapping a needle was the cause of exposure in 6.9% accidents. Among 189 registered HCWs, 66 (34.9%) performed invasive procedures without any personal protective equipment. Prophylaxis with antiretroviral drugs was necessary in 43 (22.8%) cases. As many as 60.3% of exposure incidents to potentially infectious material result from non-compliance with the relevant recommendations. Continuous education and training is critically needed to prevent occupational exposure to blood-borne infections among health care workers.

Abstract
OBJECTIVES The surveillance of HIV-transmitted drug resistance mutations (t-DRMs), including temporal trends across subtypes and exposure groups, remains a priority in the current management of the epidemic worldwide. METHODS A cross-sectional analysis of 833 treatment-naive patients from 9 of 17 Polish HIV treatment centres. Partial pol sequences were used to analyse drug resistance with a general time reversible (GTR)-based maximum likelihood algorithm used for cluster/pair identification. Mutation frequencies and temporal trends were investigated. RESULTS t-DRMs were observed in 9% of cases (5.8% for NRTI, 1.2% NNRTI and 2.0% PI mutations) and were more common among heterosexually infected (HET) individuals (13.4%) compared with MSM (8.3%, P = 0.03) or injection drug users (IDUs; 2.9%, P = 0.001) and in MSM compared with IDUs (P = 0.046). t-DRMs were more frequent in cases infected with the non-B variant (21.6%) compared with subtype B (6.6%, P < 0.001). With subtype B a higher mutation frequency was found in MSM compared with non-MSM cases (8.3% versus 1.8% for IDU + HET, P = 0.038), while non-B variants were associated with heterosexual exposure (30.4% for HET versus 4.8% for MSM, P = 0.019; versus 0 for IDU, P = 0.016). Trends in t-DRM frequencies were stable over time except for a decrease in NNRTI t-DRMs among MSM (P = 0.0662) and an NRTI t-DRM decrease in HET individuals (P = 0.077). With subtype B a higher frequency of sequence pairs/clusters in MSM (50.4%) was found compared with HET (P < 0.001) and IDUs (P = 0.015). CONCLUSIONS Despite stable trends over time, patterns of t-DRMs differed notably between transmission categories and subtypes: subtype B was associated with MSM transmission and clustering while in non-B clades t-DRMs were more common and were associated with heterosexual infections.

Phylogeographic analysis on the travel-related introduction of HIV-1 non-B subtypes to Northern Poland. INFECTION GENETICS AND EVOLUTION 2014; 27:121-30. [PMID: 25038296 DOI: 10.1016/j.meegid.2014.07.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2014] [Revised: 06/27/2014] [Accepted: 07/05/2014] [Indexed: 11/16/2022]
Abstract
Phylodynamic, sequence data based reconstructions for the surveillance of the geographic spatial spread are a powerful tool in molecular epidemiology. In this study region of origin for the set of 57 partial pol sequences derived from the patients the history of travel-related HIV transmission was analyzed using phylogeographic approach. Maximum likelihood trees based on the sets of country-annotated reference sequences were inferred for identified non-B variants. Region of sequence import was assigned using on the highest approximate likelihood ratios. Import of the A1 clades was traced to the Eastern Europe and associated with immigration from this region. Subtype C infections clustered most frequently with sequences of the South African origin while majority of subtype Ds were similar to the European clades. Subtype G sequences clustered with Portuguese lineage, CRF01_AE with Eastern or South-Eastern Asian. Eastern European, Middle African or Western African lineage was assigned for the CFR02_AG. Rare circulating recombinants originated either from Central Africa (CRF11_cpx - Democratic Republic of Congo, CRF13_cpx - Central African Republic, CRF37_cpx - Cameroon) or South America (CRF28_BF and CRF46_BF - Brazil). Import of the HIV-1 non-B variants, including recombinant forms previously rarely found in Poland and Europe is frequent among travelers. Observed founder events result in the heterosexually-driven introduction of the novel HIV-1 variants into the population.

Abstract
OBJECTIVES As a switch from chemokine (C-C motif) receptor 5 [CCR5 (R5)] to chemokine (C-X-C motif) receptor 4 [CXCR4 (X4)] HIV-1 tropism is associated with symptomatic and AIDS stages of infection, while chemokine receptor gene variants modify the tempo of HIV disease progression, we aimed to analyse the association between pretreatment HIV-1 tropism and chemokine polymorphisms known to restrict disease progression. METHODS V3 genotype tropism prediction was performed in a group of 221 treatment-naïve patients, with subsequent CCR5 Δ32 (rs333), CCR2 V64I (rs1799864), CCR5 promoter (-627 C/T; rs1799988) and CX3CR1 V249I (rs3732378) genotyping performed in 206 patients. Alleles with a protective effect were assigned positive values while risk alleles were assigned negative values to calculate genetic scores. χ(2) tests, Mann-Whitney U-tests and logistic and linear regression models were used for statistical analyses. RESULTS R5 tropism was found in 85.5% of patients (n = 189) using a false positive rate (FPR) of 5.75% and in 72.8% of patients (n = 161) using an FPR of 10%. A higher frequency of the 5.75% FPR predicted R5 tropism was associated with the CX3CR1 A allele (P = 0.027). Lower additive genetic scores were associated with an increased frequency of 5.75% FPR predicted R5 tropism (P = 0.0059), with the trend confirmed by logistic regression [odds ratio (OR) 0.5819; 95% confidence interval (CI) 0.3457-0.9795; P = 0.0416]. Viral load tended to increase with decreasing genetic score in the logistic regression analysis (slope = -0.127 ± 0.076; P = 0.095; r(2) = 0.161). CONCLUSIONS The CX3CR1 A allele and lower genetic scores may restrict the switch of HIV-1 tropism from R5 to X4. This effect may be associated with the amount of co-receptor on the cell surface. Chemokine receptor gene polymorphisms influence both disease progression and tropism variability.

IL28B CC genotype is associated with higher all-cause mortality in antiretroviral-treated HIV-infected patients. AIDS Res Hum Retroviruses 2012; 28:1640-6.

Abstract
Il28B single nucleotide polymorphisms were found to influence interferon λ expression, resulting in changes in hepatitis C virus (HCV)-RNA serum levels as well as the HIV-RNA set point prior to combined antiretroviral therapy (cART). To date, there is limited information on the influence of this polymorphism on survival in HIV-infected, treatment-naïve, and antiretroviral-treated patients. Longitudinal data from 484 patients diagnosed with HIV infection (including 406 on cART) were analyzed to investigate the association between Il28B rs 1979860 variants and all-cause mortality. Kaplan-Meyer and Cox models were used to calculate the hazard ratio associated with IL28B genotypes predictive of a greater likelihood of survival for patients prior to the introduction of cART and for patients on cART. The IL28B genotype frequencies were 41.7% (n=202) for CC, 46.5% (n=225) for CT, and 11.7% (n=57) for TT patients. The CC variant was associated with higher mortality (46 cases, 22.8%) compared to other genotypes [n=31 (13.8%) and n=7 (12.3%) for CT and TT, respectively, p=0.02]. IL28 genotypes did not influence the survival probability prior to treatment initiation (HR 1.04, 95% CI: 0.84-1.24, p=0.68). In antiretroviral-treated patients, after adjustment for gender, baseline CD4 count, CDC category at HIV diagnosis, and age (multivariate HR 1.75, 95% CI: 1.20-2.30, p=0.047), the CC genotype was associated with a decreased probability of survival when compared to the non-CC genotype (univariate HR 1.8, 95% CI: 1.28-2.34, p=0.029). IL28B rs12979860 genotypes influence mortality risk in HIV-infected, antiretroviral-treated patients. The effect may be related to higher baseline plasma HIV viremia and possibly altered immune reconstitution associated with interferon λ expression.

Abstract
BACKGROUND HIV-1 subtype D infections, which are associated with a faster rate of progression and lymphocyte CD4 decline, cognitive deficit and higher mortality, have rarely been found in native Europeans. In Northwestern Poland, however, infections with this subtype had been identified. This study aimed to analyze the sequence and clinical data for patients with subtype D using molecular phylogeography and identify transmission clusters and ancestry, as well as drug resistance, baseline HIV tropism and antiretroviral treatment efficacy. METHODS Phylogenetic analyses of local HIV-1 subtype D sequences were performed, with time to the most recent common ancestor inferred using bayesian modeling. Sequence and drug resistance data were linked with the clinical and epidemiological information. RESULTS Subtype D was found in 24 non-immigrant Caucasian, heterosexually infected patients (75% of females, median age at diagnosis of 49.5 years; IQR: 29-56 years). Partial pol sequences clustered monophyletically with the clades of Ugandan origin and no evidence of transmission from other European countries was found. Time to the most common recent ancestor was 1989.24 (95% HPD: 1968.83-1994.46). Baseline drug resistance to nucleoside reverse transcriptase inhibitors was observed in 54.5% of cases (mutations: M41L, K103N, T215S/D) with evidence of clustering, no baseline integrase or protease resistance and infrequent non-R5 tropism (13.6%). Virologic failure was observed in 60% of cases and was associated with poor adherence (p<0.001) and subsequent development of drug resistance (p = 0.008, OR: 20 (95%CI: 1.7-290). CONCLUSIONS Local subtype D represented an independently transmitted network with probably single index case, high frequency of primary drug resistance and evidence of transmission clusters.

Abstract
CCR5 inhibitors remain an attractive antiretroviral treatment option for HIV-infected patients; however, tropism testing should be utilized prior their introduction. This study analyzed genotypic HIV-1 tropisms in patients with evidence of genotypic drug resistance to antiretroviral therapies in Northwest Poland. V3 loop sequences were analyzed from plasma samples obtained from patients presenting with virologic treatment failure while on combined antiretroviral treatment and with evidence of genotypic drug resistance. Genotypic X4 and R5 tropisms were identified using the geno2pheno algorithm with a false positive rate threshold set at 10%. Clinical data for all patients examined was collected, in addition to determining the CCR5 Δ32 genotype and calculating the genotypic susceptibility score (GSS). Virologic treatment failure and the presence of drug resistant mutations were observed in 37/450 (8.4%) patients on cART (combination antiretroviral therapy) with successful tropism analysis carried out on 35 (95%) cases. In 22 (62.9%) and 13 (37.1%) cases the R5 and X4 tropisms were predicted, respectively. An association between viral X4 tropism and the M41L (P = 0.04) resistance mutation and R5 tropism and the K103N (P = 0.07) resistance mutation were observed. GSS values were lower in the group with NRTI (P = 0.01) and NNRTI resistance (P = 0.048). In the majority of the drug resistant patients, R5 tropic viruses were found. As genotypic tropism testing is easy to carry out and interpret, its use in clinical practice would be highly useful in determining the use of appropriate drug therapies.

Abstract
The aim of the study was to determine the rate of transmission of drug resistant human immunodeficiency virus-1 (HIV-1) variants among therapy-naïve HIV positive patients in Poland in the year 2008, to compare the data with the results from the years 2000 to 2007 and to monitor patterns of HIV-1 subtypes present in Polish population and their evolution. Complete protease and part of reverse transcriptase regions were sequenced from the sera of patients directed to the laboratory for drug resistance testing. The Stanford's HIVdb program was used for the interpretation of results and subtyping. The variants scoring at least "intermediate resistance" for at least one drug were considered as resistant. The results obtained were compared to those obtained in the years 2000-2007. A total of 95 patients were enrolled in the 2008 study. Homosexual transmission of infection was documented in more than 55% of all cases. The overall prevalence of transmitted drug resistance (TDR) was 5.3% (3.9% in 2007, 5.8% in 2006, and 14.1% in the years 2002-2005). The study from the years 2000 to 2001 revealed 28.7% prevalence. Preliminary analysis of the first half of 2009 shows the ratio of 7.8%. In four (4.2%) cases drug resistance was associated with protease inhibitors class, in one case (1.1%) with resistance to non-nucleoside reverse transcriptase inhibitors class. In four cases (4.2%) non-B subtype was identified (C, G, CRF01_AE, CRF02_AG). An increase of percentage of drug resistant mutants-from 3.9% (2007) to 5.3% (2008)-was recognized. In this study, TDR was limited to single classes of antiretroviral drugs. HIV-1 subtype B prevails in Poland.

Abstract
OBJECTIVE Prospective pharmacogenetic screening for the human leucocyte antigen (HLA) B*5701 allele can significantly reduce the number of cases of abacavir-related hypersensitivity among HIV-infected patients treated with this drug. The aim of this study was to establish the frequency of the HLA B*5701 variant in HIV-infected Poles. METHODS The sequence-specific primer (SSP) test was used to assess the feasibility of the introduction of such testing in clinical practice. For this purpose, 234 randomly selected HIV-positive patients were screened using a low-resolution SSP assay, with HLA B*5701-positive results confirmed using a high-resolution test. RESULTS AND CONCLUSIONS The HLA B*5701 variant was found in 11 of 234 subjects (4.7%). Testing with the selected method proved quick and reliable.

Abstract
UNLABELLED The aim of this work was quality assessment of HIV diagnostic procedures in Poland, including human and technical resources as well as laboratory practice. Sixty questionnaires were distributed among diagnostic centers to obtain qualitative data. Basing on the survey data serological control using coded panels of HIV-1/2 samples was performed. Thirty-one filled questionnaires were received (50.8%). Surveyed laboratories perform from 350 to 5500 serological screening tests per year. In most of laboratories fourth generation assays are available, while Blood Donation Centers screen the blood both with serological assays and by HIV-RNA detection. Sanitary and Epidemiological Stations and academic laboratories hold the ISO/IEC 17025 or IS0 9001:2001 accreditation, five of the surveyed centers participate in Labquality assurance and two in Quality Control in Molecular Diagnostics programs. Data of control serological testing were received from 21 centers. In the quality control assessment 194 analyses were performed with 91 true negative, 2 false negative, 96 true positive and 5 false positive results. False negative rate of % and false positive rate of 5.2% was noted for this study. CONCLUSIONS Currently, virtually no guidelines related to the HIV-diagnostics quality assurance and control in Poland are in delineated. Development of the national unified quality control system, basing on the central institution is highly desirable. National certification within the frames of the quality control and assurance program should be mandatory for all the diagnostic labs, and aim at improvement of reliability of the result distributed among clinicians and patients.

Abstract
AIM OF THE STUDY Assessment of the phenomenon of the late HIV diagnosis, as defined by the disease diagnosis alongside with the AIDS defining illness (late HIV testing). METHODS Retrospective epidemiological and clinical data analysis of patients with confirmed HIV infection, treated in the Chair and Department of Infectious Diseases and Hepatology Pomeranian Medical University, Szczecin from 2003 to 2007 in comparison to data from 1989-2002. RESULTS Data of 275 patients aged 1-71 years (mean 35+/-10) who attended the clinic for the first time in period 2003-2007 were collected. Individuals of male gender were prevailing in the analyzed group (78%), the percentage of women have been changing over the years with 32% in 2003, through 9% in 2005 to 30% in 2007. More than half of the patients presented clinical symptoms of immune deficiency: without AIDS--36% and with AIDS--22%. Lymphocyte T CD4+ count < 200 cells/microl among 118 of 275 new patients (43%) was noted. In the period 2003-2007, 59% of new patients were started on cART treatment. Late AIDS diagnosis was confirmed among 61% patients, with considerably higher frequency among men--84%. Late testers were three years older if compared to the whole of the newly diagnosed patients. The most common AIDS defining illness was the pulmonary and extrapulmonary tuberculosis, diagnosed in 13/51(25%) patients. CONCLUSIONS In most of cases HIV-infected patients are referred to the infectious diseases specialist when the clinical symptoms of immune deficiency occur, often being deeply immunocompromised. It is truly terrifying, that this situation has not truly changed since 1989. This notion creates the field for discussion on the universality and accessibility of HIV screening among Poles, in order to introduce a more common diagnostics.

Abstract
BACKGROUND The introduction of highly active antiretroviral therapy (HAART) led to a decreased incidence of the most severe opportunistic infections (OIs) in HIV-infected patients. In Poland, HAART became widely used in 1998. MATERIALS AND METHODS This study was based on data from medical records data collected in the years 2000-2002 from medical centers for HIV-infected patients in Poland. The aim of the study was to determine the incidence of opportunistic infections (OIs) and other AIDS defining illnesses (ADIs). The chi(2) test was used to determine any significant trends. RESULTS The incidence of ADIs was 6.8, 6.5 and 4.8/100 persons/year in 2000-2002, respectively. The most common diagnosed OIs were: fungal infections, tuberculosis, recurrent pneumonia, PCP and toxoplasmosis. In patients receiving HAART (HAART+) the incidence of ADIs was significantly lower than in non-ARV-treated as well as in all HIV+ (p < 0.02, p < 0.001, p < 0.001, respectively). A significant decrease in the incidence of ADIs in HAART+ patients between 2000 and 2002 (p < 0.0001) was observed. From 25% to 30% of ADIs among HAART+ patients were diagnosed within the first 3 months of antiretroviral therapy. In HAART+ patients the most common ADIs were fungal infections and tuberculosis. The diagnosis of ADIs resulted in the recognition of HIV status in 8.7-8.9% of patients. CONCLUSIONS Five years after the introduction of HAART the incidence of ADIs had declined. Fungal infections and tuberculosis were the most common OIs in HIV+ patients in Poland.

Abstract
UNLABELLED The lipodystrophy syndrome with dyslipidaemia and insulin resistance is side-effect of combined antiretroviral therapy (CART). AIM OF THE STUDY to describe the influence of CART on leptin and adiponectin concentration in connection with lipids levels in HIV-infected patients on antiretroviral therapy. BMI, serum leptin, adiponectin, triglycerides, total cholesterol, HDL- and LDL-cholesterol concentrations were measured in 56 HIV(+) patients before and on CART; average of treatment duration 38.4 +/-13.2 months. Significant increase of BMI (p=0.0268) of (22.6 +/- 3.3 before and 23.5 +/- 3.4 kg/m2 on therapy, respectively) and all analyzed lipids were found. Mean adiponectin concentration in treated patients was significantly (7.256 +/- 3.551 microg/ml) lower than mean value before treatment (8.395 +/- 3.568 microg/ml; p=0.0011). Mean values of leptin concentrations did not differ significantly (before therapy 3.721 +/- 0.347 log10; on therapy 3.1737 +/- 0.353 log10). Significant positive correlation between BMI and leptin concentrations was found before, as well as during CART (r=0.5333; p<0.0001), but negative correlation between adiponectin and leptin concentrations (r=-0.2677; p=0.042). Leptin and adiponectin concentrations did not revealed significant correlation with lipids levels before therapy. The decrease of adiponectin concentration on CART correlated negatively with total (r=-0.2912; p=0.0310) and LDL-cholesterol (r=-0.310; p=0.0225). CART lasting longer than 2 years resulted in the decrease of adiponectin concentration, with lack of influence on leptin concentration in analyzed group. The increase of total cholesterol and LDL-cholesterol in correlation with the decrease of adiponectin concentration confirms that CART induces metabolic disturbances related to higher risk of atherosclerosis and its sequel.

Abstract
OBJECTIVE To evaluate attitudes and misgivings among the medical faculty's students regarding HIV/AIDS. MATERIAL AND METHODS The 10-item questionnaires was distributed among 237 fifth year medical students regarding willingness to take care for people living with HIV/AIDS, misgivings contracting HIV, comfortable relationship with AIDS patients, attitudes towards HIV infected health care workers and support for routine HIV testing. The students filled the questionnaire before and after completing the 3-weeks long clinical training. RESULTS Neither willingness to take care nor obligation to treat patients with HIV changed significantly during the clinical training. We achieved reduction of fear of contracting HIV and an increase in feeling comfortable with HIV infected patients. There were no changes in support for HIV testing among patients and health care workers. CONCLUSIONS Medical schools should develop and frequently update programmes for continuous training on HIV/AIDS.

Abstract
PURPOSE To report the case of posterior uveitis associated with HIV infection and to discuss contemporary references on the topic. CASE REPORT A 47-years old woman with asymptomatic HIV infection developed acute posterior uveitis. The examinations for infections with CMV, Toxoplasma gondii, Treponema pallidum and Mycobacteria were negative. After failure of empirical treatment with antibiotics, ganciclovir and steroids antiretroviral treatment with three drugs was initiated on the patient. The ophthalmologic examination disclosed significant improvement after two weeks of the treatment. There have been no evidences of inflammatory disease in the eyes for 12 weeks from the starting of antiretroviral therapy. The immunologic and virologic parameters showed good control of HIV infection. CONCLUSIONS Infection with HIV appears to be a cause of uveitis.

Abstract
OBJECTIVES To determine the occurrence of pneumonias in HIV-infected patients in our hospital during 1990-1999; to evaluate the clinical significance of pneumonias in HIV-seropositive patients; to estimate the ethiology of pulmonary infection. MATERIALS AND METHODS One hundred and two HIV-infected patients, 17 (16.6%) female and 85 (83.3%) male with mean age of 29 +/- 4.5 yrs, were retrospectively analysed. All patients had a physical examination particularly concerning the clinical symptoms of pulmonary infection, X-ray exam and tuberculin skin test (PPD). The stage of HIV infection according to the 1993 CDC classification was determined. All patients had the microbiology test of sputum (Pc, TB, fungi, other pathogen). In some cases the bronchofiberoskopy with bronchoalveolar lavage (BAL) was performed. RESULTS One hundred and two HIV-positive patients had 129 episodes of pneumonia. We determine the bacterial ethiology in 94/129 (72.9%) cases--TB in 11/129 (8.5%) cases. Fourteen patients had 23 episodes of Pneumocystis carinii pneumonia (PcP). Three patients had CMV--pneumonitis, detected post mortem. In seven cases the ethiology of pulmonary infection was unknown. In summary the ethiology of pneumonia was determined in 58/129 (44.9%) cases. Thirty three patients were died. The pulmonary infections were main cause of death in 23 (67.7%) persons. CONCLUSIONS In the era of high active antiretroviral therapy (HAART) the pulmonary infections in HIV-positive patients are the main cause of death as before. The PPD test is useless in HIV-positive patients. We make a note the increase cases of TB in HIV-infected patients during the time of observations.

Abstract
The clinical manifestations were analysed in 16 patients with expanding intracranial lesions hospitalized in the period from Jan 1 1980 to Aug 31 1990. They had been admitted to hospital with the diagnosis of suspected neuroinfection. The initial manifestations and abnormalities in neurological examination might have suggested inflammatory processes in the central nervous system. Only further diagnostic procedures, especially emergency ones such as angiography and CT of the brain made possible establishing of final diagnosis and qualifying the patient for surgical intervention. The authors stress that expanding intracranial lesions should be always taken into account in patients with clinical and CSF abnormalities persisting despite ruling out of neuroinfection.
