Molecular Epidemiology and Variation of the BK Polyomavirus in the Population of Central and Eastern Europe Based on the Example of Poland.

ABSTRACT: The BK polyomavirus (BKPyV) is a widespread pathogen in humans. Polymorphism of the region encoding the VP1 protein of BKPyV provides the basis for classifying the virus into types and subtypes, whose frequency varies depending on geographic location. The aim of our study was to determine the frequency of BKPyV in the Polish population and to assess its variation by analysing polymorphism in the typing region. The study was conducted on 168 healthy, Polish volunteers, whose blood (plasma) and urine were sampled. The virus was detected using PCR, products, sequenced and subjected to bioinformatic analysis. In addition, viral load was assessed by qPCR. The presence of the genetic material of the BK virus was noted in 61/168 urine samples but in none of the plasma sample. Sequencing and phylogenetic analysis confirmed that the BKPyV isolates were of types I and IV, dominant in Europe (63.93% and 36.07%, respectively). All isolates from genotype I belonged to subtype Ib-2, showing polymorphism at position 1809 with a frequency of 61.54% (G1809A) and 38.46% (G1809C). To the best of our knowledge, this is the first study of this magnitude on the genetic variation of BKPyV among healthy volunteers in Poland.

Project description:IntroductionThe COVID-19 pandemic has been challenging time for medical care, especially in the field of infectious diseases (ID), but it has also provided an opportunity to introduce new solutions in HIV management. Here, we investigated the changes in HIV service provision across Central and Eastern European (CEE) countries before and after the COVID-19 outbreak.MethodsThe 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.ResultsTwenty-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 country. HIV care was based in ID hospitals plus out-patient clinics (52%), was centralized in big cities (52%), and was publicly financed (96%). Integrated services were available in 21 clinics (91%) with access to specialists other than ID, including psychologists in 71.5% of the centers, psychiatrists in 43%, gynecologists in 47.5%, dermatologists in 52.5%, and social workers in 62% of all clinics. Patient-centered care was provided in 17 centers (74%), allowing consultations and tests to be planned for the same day. Telehealth tools were used in 11 centers (47%) before the COVID-19 pandemic outbreak, and in 18 (78%) after (p = 0.36), but were represented mostly by consultations over the telephone or via e-mail. After the COVID-19 outbreak, telehealth was introduced as a new medical tool in nine centers (39%). In five centers (28%), no new services or tools were introduced.ConclusionsAs a consequence of the COVID-19 pandemic, tools such as telehealth have become popularized in CEE countries, challenging the traditional approach to HIV care. These implications need to be further evaluated in order to ascertain the best adaptations, especially for HIV medicine.
