The Euroguidelines CEE Network Group members were invited to respond to a 27-item survey including questions on PrEP (response rate 91.6%). PrEP was licensed in 68.2%; 95 centers offered PrEP and the estimated number on PrEP was around 9000. It was available in daily (40.1%), on-demand (13.3%), or both forms (33.3%). The access rate was <1–80%. Three major barriers for access were lack of knowledge/awareness among people who are in need (59.1%), not being reimbursed (50.0%), and low perception of HIV risk (45.5%). Non-occupational PEP was available in 86.4% and was recommended in the guidelines in 54.5%. It was fully reimbursed in 36.4%, only for accidental exposures in 40.9%, and was not reimbursed in 22.72%. Occupational PEP was available in 95.5% and was reimbursed fully. Although...

The Central and East Europe (CEE) region consists of countries with highly diversified HIV epidemics, health care systems and socioeconomic status. The aim of the present study was to describe variations in CKD burden and care between countries. The Euroguidelines in the CEE Network Group includes 19 countries and was initiated to improve the standard of care for HIV infection in the region. Information on kidney care in HIV-positive patients was collected through online surveys sent to all members of the Network Group. Almost all centres use regular screening for CKD in all HIV (+) patients. Basic diagnostic tests for kidney function are available in the majority of centres. The most commonly used method for eGFR calculation is the Cockcroft–Gault equation. Nephrology consultation is available in all centres. The median frequency of CKD was...

In 2014, data were collected from 24 Central and Eastern European countries using a 38-item questionnaire. All countries reported mandatory screening of blood and organ donors for HIV. Other groups subjected to targeted screening included people who inject drugs (PWID) (15/24, 62.5%), men who have sex with men (MSM) (14/24, 58.3%), and sex workers (12/24, 50.0%). Only 14 of the 24 countries (58.3%) screened pregnant women. The percentages of late presentation and advanced disease were 40.3% (range 14-80%) and 25.4% (range 9-50%), respectively. There was no difference between countries categorized by income or by region in terms of the percentages of persons presenting late or with advanced disease. The availability of newer antiretroviral drugs (rilpivirine, etravirine, darunav...

Here, we investigated the changes in HIV service provision across Central and Eastern European (CEE) countries before and after the COVID-19 outbreak. Methods: The Euroguidelines in Central and Eastern Europe Network Group consists of experts in the field of ID from 24 countries within the CEE region. Between 11 September and 29 September 2021, the group produced an on-line survey, consisting of 32 questions on models of care among HIV clinics before and after the SARS-CoV-2 outbreak. Results: Twenty-three HIV centers from 19 countries (79.2% of all countries invited) participated in the survey. In 69.5% of the countries, there were more than four HIV centers, in three countries there were four centers (21%), and in four countries there was only one HIV center in each...

Therefore, we aimed to review the HIV continuum of care and hard-to-reach populations for each step of the continuum in Central, Eastern and South Eastern Europe. Methods: Euro-guidelines in Central and Eastern Europe (ECEE) Network Group were created in February 2016. The aim of the network was to review the standards of HIV care in the countries of the region. Information about each stage of HIV continuum of care and hard-to-reach populations for each stage was collected through on-line surveys. Respondents were ECEE members chosen based on their expertise and involvement in national HIV care. Data sources (year 2016) used by respondents included HIV Clinics electronic databases, Institutes of Public Health, Centres for AIDS Prevention, and HIV Programme Reviews. Results: The percentage of people living with HIV (PLHIV) linked to HIV care after HIV diagnosis was...

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.

We conducted a cross-sectional survey of 180 PLWHIV aged 18 years+ in Armenia who were on cART and used the 36-Item Short-Form Health Survey to assess HRQoL. The highest HRQoL domain score was 85.3 (SD 24.7) for physical functioning, followed by 82.1 (SD 25.0) for pain, 77.9 (SD 24.2) for social functioning, 76.4 (SD 39.6) for emotional role-functioning, 71.1 (SD 39.7) for physical role-functioning, and 64.0 (SD 20.3) for energy/fatigue, 63.7 (SD 22.7) for emotional well-being and 63.4 for general health 63.4 (SD 21.2). In the physical domain, chronic comorbidities and low emotional support were associated with worse physical functioning, physical role-functioning, general health and pain scores (p < 0.05). Unemployment and hepatitis C coinfection were associated with worse physical role functioning and pain scores (p < 0.01). As for mental...

Vaccination is a safe and effective method of prevention against many infectious diseases, including COVID-19. Here we investigate the strategies for national COVID-19 vaccination programmes across central and eastern Europe and the inclusion of PLWH in vaccination programmes. METHODS The Euroguidelines in Central and Eastern Europe Network Group consists of experts in the field of infectious diseases from 24 countries in the region. Between 1 November 2020 and 19 March 2021 the group proceeded an on-line survey consisting of 20 questions. RESULTS Twenty-two countries (out of 24 invited) participated in the survey and 20/22 countries in the period between December 2020 and March 2021 had already started their COVID-19 vaccination programme. In total, seven different vaccines were used by participating countries. In 17/21 countries (81%), vaccinated persons were centralized within the national registry. In 8/21 countries (38%) PLWH were prioritized for vaccination (the Czech Republic, Greece, Hungary, Lithuania, Montenegro, Romania, Slovakia, Slovenia) and the Czech Republic, Greece and Serbia had put in place national guidelines for vaccination of PLWH. In 14/20 countries (70%) vaccination was only provided by designated centres. Eighteen respondents (18/21; 85.7%) reported that they planned to follow up HIV patients vaccinated against COVID-19, mainly by measuring antibody levels and checking COVID-19 incidence (11/21; 52.3%). CONCLUSIONS This survey-based study suggests that there are significant differences in terms of prioritizing PLWH, the types of vaccines used, vaccination coverage, and the development and implementation of a vaccination programmes within the region. Regardless of heterogenicity and existing barriers within the region, systematic vaccination in PLWH should have the highest priority, especially in those with severe immunodeficiency, risk factors, and in the elderly, aiming for prompt and high vaccination coverage.

Darunavir is a second-generation protease-inhibitor used with ritonavir (DRV/r) and two nucleoside reverse-transcriptase inhibitors as an option in first-line antiretroviral treatment (ART). Methods. We systematically reviewed randomized controlled trials (RCTs) of DRV/r versus other regimens in patients initiating ART. We searched five bibliographic databases and other key resources. We had no language limitations. We assessed bias risk with the Cochrane tool and used GRADE to assess evidence quality. We report findings in terms of risk ratio (RR) with 95% confidence intervals (CI). Findings. Three RCTs met inclusion criteria. In plasma viral load suppression, DRV/r outperformed ritonavir-boosted lopinavir at 48 weeks (RR 1.13, 95% CI 1.03–1.25), 96 weeks (RR 1.11, 95% CI 1.02–1.21), and 192 weeks (RR 1.20, 95% CI 1.07–1.35). DRV/r was similar to dolutegravir at 48 weeks (RR 0.96, 95% CI 0.87–1.06) but less effective at 96 weeks (RR 0.84, 95% CI 0.75–0.93). At 96 weeks,...
