RESUMO

OBJECTIVES: Late presentation (LP) at HIV diagnosis is associated with worse prognosis and an increase in the number of new infections. We analyse the proportion of patients diagnosed late and factors related to LP in Poland in 2016-2017. METHODS: Data were obtained from 13 out of 17 HIV centres in Poland from 2016 and 2017, including date of diagnosis, age, sex, transmission route, anti-hepatitis C virus (anti-HCV), Venereal Diseases Research Laboratory (VDRL) antibodies, AIDS diagnosis, baseline HIV viral load and CD4 count. RESULTS: Out of 1522 patients, 88.9% were male with median age of 33.6 years. Men who have sex with men (MSM) comprised 69.4% of all new infections, heterosexual route of transmission (HTX) 18.2% and injecting drug use (IDU) 4.7%. Late presenters comprised 44.8% of the study group. Factors associated with LP were female sex [odds ratio (OR) = 1.5, 95% confidence interval (95% CI): 1.09-2.08], older age (OR = 1.59, 95% CI: 1.42-1.79 per decade), route of transmission (HTX: OR = 1.96, 95% CI: 1.50-2.56; IDU: OR = 3.17, 95% CI: 1.92-5.37), positive HCV results (OR = 1.90, 95% CI: 1.23-2.95) and syphilis diagnosis (OR = 2.06, 95% CI: 2.29-3.31). Adjusting for these factors, the only independent factors associated with LP were age (OR = 1.52, 95% CI: 1.35-1.71) and route of transmission (HTX: OR = 1.73, 95% CI: 1.23-2.44; IDU: OR = 2.24, 95% CI: 1.25-4.10). CONCLUSIONS: Late presentation in Poland follows European trends. A total of 44.8% of all newly diagnosed patients in Poland continue to present late or at the AIDS stage. Independent factors associated with LP/AIDS were older age, IDU and HTX. Patients from these groups should be targeted to improve early diagnosis and medical care.

RESUMO

OBJECTIVES: Pre-exposure prophylaxis (PrEP) for HIV infection is an important intervention for control of the HIV epidemic. The incidence of HIV infection is increasing in the countries of Central and Eastern Europe (CEE). Therefore, we investigated the change in PrEP use in CEE over time. METHODS: The Euroguidelines in Central and Eastern Europe (ECEE) Network Group was initiated in February 2016 to compare standards of care for HIV and viral hepatitis infections in CEE. Data on access to PrEP were collected from 23 countries through online surveys in May-June 2017 (76 respondents) and in November 2018-May 2019 (28 respondents). RESULTS: About 34.2% of respondents stated that tenofovir/emtricitabine (TDF/FTC) was licensed for use in their country in 2017, and 66.7% that it was licensed for use in 2018 (P = 0.02). PrEP was recommended in national guidelines in 39.5% of responses in 2017 and 40.7% in 2018 (P = 0.378). About 70.7% of respondents were aware of "informal" PrEP use in 2017, while 66.6% were aware of this in 2018 (P = 0.698). In 2018, there were 53 centres offering PreP (the highest numbers in Poland and Romania), whereas six countries had no centres offering PreP. The estimated number of HIV-negative people on PreP in the region was 4500 in 2018. Generic TDF/FTC costs (in Euros) ranged from €10 (Romania) to €256.92 (Slovakia), while brand TDF/FTC costs ranged from €60 (Albania) to €853 (Finland). CONCLUSIONS: Although the process of licensing TDF/FTC use for PrEP has improved, this is not yet reflected in the guidelines, nor has there been a reduction in the "informal" use of PrEP. PrEP remains a rarely used preventive method in CEE countries.

RESUMO

The EuroSIDA study was initiated in 1994 and follows adult people living with HIV (PLHIV) in 100 collaborating clinics across 35 countries covering all European regions, Israel and Argentina. The study aims to study the long-term virological, immunological and clinical outcomes of PLHIV and to monitor temporal changes and regional differences in outcomes across Europe. Annually collected data include basic demographic characteristics, information on AIDS- and non-AIDS-related clinical events, and details about antiretroviral therapy (ART), hepatitis C treatment and other medications, in addition to a range of laboratory values. The summer 2016 data set held data from a total of 23 071 individuals contributing 174 481 person-years of follow-up, while EuroSIDA's unique plasma repository held over 160 000 samples. Over the past 25 years, close to 300 articles have been published in peer-reviewed journals (h-index 52), covering a range of scientific focus areas, including monitoring of clinical and virological outcomes, ART uptake, efficacy and adverse events, the influence of hepatitis virus coinfection, variation in the quality of HIV care and management across settings and regions, and biomarker research. Recognizing that there remain unresolved issues in the clinical care and management of PLHIV in Europe, EuroSIDA was one of the cohorts to found The International Cohort Consortium of Infectious Disease (RESPOND) cohort consortium on infectious diseases in 2017. In celebration of the EuroSIDA study's 25th anniversary, this article aims to summarize key scientific findings and outline current and future scientific focus areas.

RESUMO

The aim of this study was to evaluate the baseline demographics and real-life efficacy of direct acting antivirals (DAAs) in HIV-HCV-positive patients as compared to patients with HCV monoinfection. The analysis included 5690 subjects who were treated with DAAs: 5533 were HCV-positive and 157 were HIV-HCV-positive. Patients with HCV-monoinfection were older (p < .0001) and in HIV-HCV group there were more men (p < .0001). Prevalence of genotype 1a (p = .002), as well as of genotypes 3 and 4 (p < .0001) was higher in HIV-HCV-coinfected patients. Genotype 1b was more frequent (p < .0001) in the HCV-mono-infection group. Patients with HCV-monoinfection had a higher proportion of fibrosis F4 (p = .0004) and lower proportion of fibrosis F2 (p < .0001). HIV-HCV-coinfected individuals were more often treatment-naïve (p < .0001). Rates of sustained viral response after 12 weeks did not differ significantly between both groups (95.9% versus 97.3% in coinfection and monoinfection group, respectively; p > .05). They were, however, influenced by HCV genotype (p < .0001), stage of hepatic fibrosis (p < .0001), male sex (p < .0001), BMI (p = .0001) and treatment regimen modifications (p < .0001). Although factors associated with worse response to therapy (male sex, genotype 3) occurred more often in the HIV coinfection group, real-life results of DAAs did not differ significantly between both populations.

RESUMO

OBJECTIVES: The aim of the study was to establish a methodology for evaluating the hepatitis C continuum of care in HIV/hepatitis C virus (HCV)-coinfected individuals and to characterize the continuum in Europe on 1 January 2015, prior to widespread access to direct-acting antiviral (DAA) therapy. METHODS: Stages included in the continuum were as follows: anti-HCV antibody positive, HCV RNA tested, currently HCV RNA positive, ever HCV RNA positive, ever received HCV treatment, completed HCV treatment, follow-up HCV RNA test, and cure. Sustained virological response (SVR) could only be assessed for those with a follow-up HCV RNA test and was defined as a negative HCV RNA result measured > 12 or 24 weeks after stopping treatment. RESULTS: Numbers and percentages for the stages of the HCV continuum of care were as follows: anti-HCV positive (n = 5173), HCV RNA tested (4207 of 5173; 81.3%), currently HCV RNA positive (3179 of 5173; 61.5%), ever HCV RNA positive (n = 3876), initiated HCV treatment (1693 of 3876; 43.7%), completed HCV treatment (1598 of 3876; 41.2%), follow-up HCV RNA test to allow SVR assessment (1195 of 3876; 30.8%), and cure (629 of 3876; 16.2%). The proportion that achieved SVR was 52.6% (629 of 1195). There were significant differences between regions at each stage of the continuum (P < 0.0001). CONCLUSIONS: In the proposed HCV continuum of care for HIV/HCV-coinfected individuals, we found major gaps at all stages, with almost 20% of anti-HCV-positive individuals having no documented HCV RNA test and a low proportion achieving SVR, in the pre-DAA era.

RESUMO

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.

RESUMO

It is yet unclear if people infected with human immunodeficiency virus (HIV+) on stable, combined antiretroviral therapies (cARTs) decline with age at the same or greater rate than healthy people. In this study, we examined independent and interactive effects of HIV, age, and HIV-related clinical parameters on neuropsychological functioning and brain regional volume in a sizable group of Polish HIV+ men receiving cART. We also estimated the impact of nadir CD4 cell count, CD4 cell count during participation in the study, duration of HIV infection, or duration of cART along with age. Ninety-one HIV+ and 95 control (HIV-) volunteers ages 23-75 completed a battery of neuropsychological tests, and 54 HIV+ and 62 HIV- of these volunteers participated in a brain imaging assessment. Regional brain volume in the cortical and subcortical regions was measured using voxel-based morphometry. We have found that HIV and older age were independently related to lower attention, working memory, nonverbal fluency, and visuomotor dexterity. Older age but not HIV was associated with less volume in several cortical and subcortical brain regions. In the oldest HIV+ participants, age had a moderating effect on the relationship between the duration of cART and visuomotor performance, such as that older age decreased speed of visuomotor performance along with every year on cART. Such results may reflect the efficacy of cART in preventing HIV-associated brain damage. They also highlight the importance of monitoring neuropsychological functioning and brain structure in HIV+ patients. This is particularly important in older patients with long adherence to cART.

RESUMO

OBJECTIVES: Pre-exposure prophylaxis (PrEP) for HIV infection has been introduced in only a few European countries. We investigated the potential to provide PrEP in the Central and Eastern European region, and in neighbouring countries. METHODS: The Euroguidelines in Central and Eastern Europe (ECEE) Network Group was formed in February 2016 to review standards of care for HIV infection in the region. Information related to PrEP was collected through on-line surveys. Respondents were recruited by ECEE members based on their involvement in HIV care. RESULTS: Seventy-six respondents from 23 countries participated in the survey. Twenty-six (34.2%) respondents reported that PrEP [tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC)] was registered by the drug registration authority in their country. Fifty-three (70.7%) respondents reported being aware of 'informal' PrEP use in their country. If they had access to PrEP, 56 (74.7%) would advise its use in their practice. Forty-five (59.2%) respondents had concerns regarding PrEP use, and 10 (13.3%) expressed the need for more training. Most of the respondents (88.2%) would provide PrEP to people with high-risk behaviours. CONCLUSIONS: PrEP is already used informally in some countries in the region. Physicians are keen to use PrEP if and when it is accessible. Obstacles towards implementing PrEP in those countries were mostly related to lack of national guidelines, drug registration and governmental strategy.

RESUMO

OBJECTIVES: The Maraviroc Switch (MARCH) study week 48 data demonstrated that maraviroc, a chemokine receptor-5 (CCR5) inhibitor, was a safe and effective switch for the ritonavir-boosted protease inhibitor (PI/r) component of a two nucleos(t)ide reverse transcriptase inhibitor [N(t)RTI] plus PI/r-based antiretroviral regimen in patients with R5-tropic virus. Here we report the durability of this finding. METHODS: MARCH, an international, multicentre, randomized, 96-week open-label switch study, enrolled HIV-1-infected adults with R5-tropic virus who were stable (> 24 weeks) and virologically suppressed [plasma viral load (pVL) < 50 HIV-1 RNA copies/mL]. Participants were randomized to continue their current PI/r-based regimen (PI/r) or to switch to MVC plus two N(t)RTIs (MVC) (1:2 randomization). The primary endpoint was the difference in the proportion with pVL < 200 copies/mL at 96 weeks. The switch arm was defined as noninferior if the lower limit of the 95% confidence interval (CI) for the difference was < -12% in the intention-to-treat (ITT) population. Safety endpoints (the difference in the mean change from baseline or a comparison of proportions) were analysed as key secondary endpoints. RESULTS: Eighty-two (PI/r) and 156 (MVC) participants were randomized and included in the ITT analysis; 71 (87%) and 130 (83%) were in follow-up and on therapy at week 96. At week 96, 89.0% and 90.4% in the PI/r and MVC arms, respectively, had pVL < 50 copies/mL (95% CI -6.6, 10.2). Moreover, in those switching away from PI/r, there were significant reductions in mean total cholesterol (differences 0.31 mmol/L; P = 0.02) and triglycerides (difference 0.44 mmol/L; P < 0.001). Changes in CD4 T-cell count, renal function, and serious and nonserious adverse events were similar in the two arms. CONCLUSIONS: MVC as a switch for a PI/r is safe and effective at maintaining virological suppression while having significant lipid benefits over 96 weeks.

RESUMO

The aim of the EpiTer-2 study was to analyse patient characteristics and their medication for HCV infection in Poland at the beginning of the interferon-free era. Analysis of data of HCV infected patients treated during the initial period of availability of interferon-free regimens in Poland, who started therapy after 1 July 2015 and had available an efficacy evaluation report before 30 June 2017 was undertaken. A total of 2879 patients with chronic hepatitis C were entered, including 46% with liver cirrhosis. The most common was genotype 1b (86.8%). The study population was gender balanced, the majority of patients were overweight or obese and 69% presented comorbidities, with the highest prevalence that for hypertension. More than half of patients were retreated due to failure of previous therapy with pegylated interferon and ribavirin. Almost two-third of patients received current therapy with ombitasvir/paritaprevir/ritonavir±dasabuvir (OPrD) ±ribavirin. Other patients received mostly sofosbuvir-based regimens including combination with ledipasvir and pegylated interferon and ribavirin for genotype 3-infected patients. Efficacy of treatment in the whole study population measured as intent-to-treat analysis was 95%. The most frequent regimen, administered for patients infected with genotype 1b, was 12 weeks of OPrD, resulting in an SVR rate of 98%. At least one adverse event was reported in 38% of patients, and the death rate was 0.8%. In conclusion, data from the EpiTer-2 study confirmed the excellent efficacy and safety profile of the real-world experience with recently introduced therapeutic options for genotype 1 HCV infection, but demonstrated weakness of the current therapeutic programme regarding genotype 3 infections.

RESUMO

OBJECTIVES: The objective of this paper is to summarize the outcomes of the Euroguidelines in Central and Eastern Europe (ECEE) conference held in Warsaw in February 2016. The main aim of this conference was to facilitate a discussion on European AIDS Clinical Society (EACS) guidelines implementation across the region and neighbouring countries and to present the current obstacles in benchmarking HIV care in Europe. METHODS: During a 2-day meeting, there were country-based presentations using a predefined template so as to make the data comparable and focus the discussion. Areas covered were country epidemiology, surveillance, national strategy for treatment and prevention, standards of care, access to care and treatment availability. Each participant filled in a questionnaire investigating HIV guidelines usage per country. RESULTS: In total, 16 Central and Eastern Europe (CEE) and neighbouring countries were represented at the conference: Albania, Armenia, Belarus, Croatia, Czech Republic, Estonia, Georgia, Hungary, Lithuania, Moldova, Poland, Romania, Russia, Serbia, Slovakia and Turkey. EACS guidelines version 7.1 were used in 14 (87%) countries. In 11 (69%) countries, national guidelines were available, of which eight had been recently updated. Half of the countries declared that they use World Health Organization (WHO) and Department of Health and Human Services (DHHS) guidelines, over one-third the European Centre for Disease Prevention and Control (ECDC) HIV testing guidelines and one in five the International Antiviral Society-USA (IAS-USA) Panel guidelines from 2012. CONCLUSIONS: Participants declared their will to promote the widespread use of EACS guidelines for HIV infection in the CEE region and neighbouring countries by signing the Warsaw Declaration. They also emphasized the need to increase publishing of data from national cohorts in that region.

RESUMO

BACKGROUND: Syphilis is an infection frequently seen with HIV, and European guidelines on the management of syphilis suggest that HIV-infected patients may have an increased risk of early neurological involvement, sometimes asymptomatic. Recent study shows a relationship between neurosyphilis and cerebrospinal fluid (CSF) HIV viral load (VL), which in turn may be associated with subsequent neurocognitive decline. OBJECTIVES AND METHODS: The aim of the study was estimation of the frequency of neurosyphilis among HIV-positive patients with early syphilis. The study included all patients diagnosed with early syphilis who had lumbar puncture performed in the years 2008-2012. Analysis included CSF parameters (serology, mononuclear cells, protein, glucose, chloride and lactate levels), CD4 count, serum VL and highly active antiretroviral therapy (HAART). Diagnosis of neurosyphilis was confirmed by CSF serology [positive fluorescent treponemal antibody and/or Venereal Disease Research Laboratory (VDRL) test(s)] and increased number of mononuclear cells. Statistical analysis included χ(2) tests with an accepted significance level of P < 0.05. RESULTS: Lumbar puncture was performed in 72 patients, all men, with median age 33 (interquartile range 11) years. Neurosyphilis was confirmed in 65 (90.28%) of the patients. No statistically significant association between CSF parameters and CD4 count was found. However, statistically significant associations were found only between pleocytosis and serum VL > 1000 HIV-1 RNA copies/mL (P = 0.0451), as well as HAART treatment (P = 0.0328). The proportion of confirmed neurosyphilis cases, also in patients with low serum VDRL titres, was very high. CONCLUSIONS: Considering the high proportion of patients who objected to having LP performed in the absence of neurological symptoms and the risk associated with this procedure, it may be preferable to use treatments with good CNS penetration in all HIV-positive patients with early syphilis.

RESUMO

OBJECTIVES: The objective of the 1st European AIDS Clinical Society meeting on Standard of Care in Europe was to raise awareness of the European scenario and come to an agreement on actions that could be taken in the future. METHODS: Data-driven presentations were given on specific topics followed by interactive panel discussions. RESULTS: In Eastern European countries, the epidemic is largely driven by injecting drug use, in contrast with Western Europe where the infection mainly occurs through heterosexual contact. A high proportion of people living with HIV remain unaware of their infection. Substantial differences exist in Eastern Europe and Central Asia with respect to treatment coverage, regimen availability and continuity of drug supply. In 2012, tuberculosis case notification rates were 5-10 times higher in Eastern Europe compared with Western Europe, with an alarming proportion of newly diagnosed multi-drug-resistant cases. Hepatitis C is widespread in selected geographical areas and risk groups. CONCLUSIONS: The key conclusion from the meeting was that a high-priority group of actions could be identified, including: increasing HIV awareness and testing, improving training for health care providers, ensuring equitable patient access to treatments and diagnostics for HIV and comorbidities, and implementing best practices in infection control and treatment of HIV-infected patients coinfected with tuberculosis and hepatitis C virus, for whom direct acting antiviral treatment. should be considered.

RESUMO

OBJECTIVES: Linkage to care after HIV diagnosis remains underinvestigated in Europe, yet delays in linkage to care are an important obstacle to controlling the HIV epidemic. The Test and Keep in Care (TAK) project aims to determine the prevalence of HIV-positive persons who are lost or late to care and factors associated with this. METHODS: Data from community-based voluntary counselling and testing that occurred in 2010-2011 were linked with data from HIV clinics using unique test numbers. Persons not registered in HIV clinics were considered lost to care (LTC). For statistical analysis, nonparametric tests were used for comparison, and a multivariable logistic regression model was developed that included all variables with P<0.1 from the univariable models. RESULTS: A total of 110 persons were diagnosed as HIV-positive: 91% lived in central Poland, 5% were female and 71% were men who have sex with men (MSM). Forty-seven (42%) persons were LTC, seven of whom did not collect their enzyme-linked immunosorbent assay (ELISA) test result. Of those who registered, 75% registered within 1 month from HIV diagnosis, and 54% were late presenters. LTC individuals were more likely to have heterosexual or bisexual orientation, to have >20 sexual partners, to not be in a relationship with an HIV-positive partner, to not use condoms, and to be taking their first HIV test. In a logistic regression model, after adjusting for these factors, using condoms in a stable relationship decreased the odds of LTC by 72% (odds ratio 0.28; confidence interval 0.11-0.67). CONCLUSIONS: Integration into care after HIV diagnosis requires improvement. Our results suggest that broadening awareness and counselling about sexual risks may have a positive impact.

RESUMO

Alisporivir (ALV) is an oral, investigational host-targeting agent, with pangenotypic activity against hepatitis C virus (HCV). This randomized, double-blind, placebo-controlled, Phase II study explored the efficacy and safety of ALV with peginterferon-α2a/ribavirin (PR) in patients with chronic HCV genotype 1 infection in whom prior PR had failed (43% relapsers, 34% null responders and 23% partial responders). Four-hundred-and-fifty-nine patients were randomized (1:1:1:1) to ALV 600 mg once daily (QD), ALV 800 mg QD, ALV 400 twice daily (BID) or placebo plus PR for 48 weeks. When the global ALV trial programme was put on clinical hold, all patients in this study had received ≥31 weeks of randomized treatment; patients completed 48 weeks on PR alone. All ALV groups demonstrated superior rates of complete early virologic response (cEVR; primary endpoint) vs PR alone (P ≤ 0.0131), with highest cEVR rate seen with ALV 400 mg BID (74% vs 36% with PR alone; P < 0.0001). Respective SVR12 rates (key secondary endpoint) were 65% vs 26% in prior relapsers, 63% vs 5% in partial responders and 68% vs 3% in null responders. In patients who received >40 weeks of randomized treatment, the SVR12 rate was 89% for ALV 400 mg BID vs 30% for PR alone (P = 0.0053). Rates of viral breakthrough and relapse were lowest with ALV 400 mg BID. One case of pancreatitis (fully recovered) occurred with ALV/PR. Common AEs were headache, fatigue, anaemia, neutropenia and nausea. Hypertension was infrequent, but more common with ALV. ALV merits further investigation in interferon-free regimens in combination with direct-acting antiviral agents.

RESUMO

OBJECTIVES: Syphilis recognition in HIV-positive patients has important implications. Initial data from this study, established in June 2012 to better understand the natural history of syphilis and treatment response, examine the characteristics of patients including sexual behaviour, rates of concurrent sexually transmitted infections (STI) and type of treatment given. METHODS: Patients were recruited from Ireland, Poland and Germany. Data gathered included demographics, method of syphilis acquisition, stage of syphilis infection, HIV status, nadir and current CD4 counts and HIV viral suppression rates. Data were then subanalysed into HIV-positive and HIV-negative groups. RESULTS: Of 175 patients recruited, 68% were HIV-positive and 86.3% were men who have sex with men. Most HIV-positive patients presented with secondary syphilis (55.7% vs 13.2%) (p=0.0001) while the majority of HIV-negative patients had primary syphilis noted at the time of recruitment (47.2% vs18.9%, p=0.0002). Approximately half of all patients had a HIV RNA viral load <40 copies/mL (55%). Previous syphilis infection occurred more frequently in HIV-positive than HIV-negative patients (p=0.0001). Concurrent STIs at the time of syphilis diagnosis were found in 26.8%, of whom 31 (25.4%) were HIV-positive (p=0.64). HIV-positive patients received doxycycline more frequently than their HIV-negative counterparts (33.6% vs 1.9%, p=0.0001) while HIV-negative patients were treated with long-acting penicillin in 88.7% of cases vs 58% of HIV-positive patients (p=0.0002). CONCLUSIONS: A 40% rate of unsuppressed viraemia, high levels of STIs and varying treatment regimens represent a public health risk for Europe, suggesting the model of sexual healthcare delivery in HIV-positive patients requires further evaluation.

RESUMO

Hepatitis C virus (HCV) variability affects viral-host interactions. We analysed HCV 5'untranslated region (5'UTR) in sera and peripheral blood mononuclear cells (PBMC) from chronic hepatitis C patients undergoing antiviral treatment. We studied 139 patients treated with pegylated interferon and ribavirin. The primary endpoint was a sustained virological response (SVR) defined as negative HCV RNA level 24 weeks after the end of therapy. 5'UTR was analysed by single-strand conformational polymorphism (SSCP) and sequencing. The pretreatment SSCP pattern in serum and PBMC differed in 26 (18.7%) patients. During therapy, the SSCP pattern remained stable in 65 (60.8%) patients, number of bands declined in 16 (15.0%), and in 18 (16.8%) patients, changes were qualified as 'shift' indicating change in band positions. In univariate analysis, there was a significant (P ≤ 0.05) positive association between SVR and pretreatment serum and PBMC dissimilarities, initial viral load <10(6) IU/mL, IL-28B CC genotype of the rs12979860 single nucleotide polymorphism and change in the SSCP band pattern (either 'shift' or decline) In multivariable analysis, only low initial viral load, IL-28B genotype, and changes in the SSCP band pattern were independent factors associated with SVR. In conclusion, stability of 5'UTR correlated with infection persistence, while changes correlated with SVR.

RESUMO

It has been reported that hepatitis C virus (HCV) RNA may be present in serum and/or lymphoid cells in the absence of specific circulating antibodies. The current study analysed seronegative HCV infection in patients with lymphoproliferative disorders. We studied 77 anti-HCV-negative patients (45 male and 32 female, mean age 54.8 ± 14.2 years) with various lymphoproliferative disorders. HCV-RNA was detected by RT-PCR in plasma, peripheral blood mononuclear cells (PBMC) and bone marrow. Furthermore, the presence of viral nonstructural protein 3 (NS3) was determined in PBMC and bone marrow by immunostaining. HCV-RNA was detectable in at least one compartment in 27 (35.1%) patients. Viral RNA was found in bone marrow in 22 patients (28.6%), in PBMC in 13 (16.9%) and in plasma in 10 (13%) patients. In nine patients, evidence of infection was confined to the bone marrow compartment. Viral load in HCV-RNA-positive plasma ranged from 15 to 1.17 × 10(3) IU/mL. NS3 was detected in all but two HCV-RNA-positive bone marrow samples and in all but one HCV-RNA-positive PBMC samples. All 27 HCV-RNA-positive patients remained anti-HCV-negative when tested again after 6-12 months, but only four remained HCV-RNA positive. In conclusion, among patients with lymphoproliferative disorders, HCV can be present in plasma, PBMC and bone marrow despite the lack of circulating specific antibodies. Further studies are required to analyse the phenomenon of seronegative infection and to determine whether such patients are infectious.
