In Poland storage of human biological samples takes place at most universities and scientific institutions conducting research projects in the field of biomedicine. The First International Biobanking Conference organized by the Ministry of Science and Higher Education in 2014 shed a light on the situation of Polish biobanking infrastructures. The country has around 40 large biorepositories, which store unique biological material such as whole brains, muscle fibers from patients with rare diseases, as well as thousands of samples from patients with lifestyle diseases. There are only two population-based biobanks working locally and several disease-oriented biobanks specializing mainly in oncological diseases. Consortium BBMRI.pl created plans for establishing a Polish Network of Biobanks, with national node which meets standards for biobanks and cooperation to guarantee development of biomedical sciences and international collaboration between Poland and other countries. The Polish network will enhance research activities, due to better visibility of samples and data that are stored in the national biobanking catalogue. However, it requires more than a comprehensive understanding of all benefits. The list of examples of benefits can be presented as follows: (i) a reduction of the duration and cost of clinical trials and subsequent time to market for anticancer drugs; (ii) more precise patient diagnosis and the associated impact on treatment and lower healthcare costs for providers, individuals, and the nation; (iii) improvements in research experiment time frames and data efficiencies; (iv) convergence to an industry standards for biospecimen quality; (v) optimization of capital infrastructure and IT technology.

Many types of biomedical research projects depend on high-quality biological material with a data set attached. The Quality Management System (QMS) is focused on operational standards for all organizational activities to ensure that the described quality of each procedure, product, or service is guaranteed. The implementation of the QMS is necessary for the provision of both high quality and repeatability of processes in research laboratories. The current status of implementation of the QMS is determined according to the ''Organisation of Polish Biobanking Network'' within the project ''Biobanking and Biomolecular Resources Research Infrastructure BBMRI-ERIC'' supported by the Polish Ministry of Science and Higher Education-decision number DIR/WK/2017/01. According to the above, preliminary audits in six Polish institutions were conducted and reports with recommendations concerning the implementation and improvement of the QMS in Polish biobanks were prepared. During all audits, 13 QMS main areas were analyzed. All audited units belong to the BBMRI.pl consortium, which is responsible for the creation of the Polish Biobanking Network within the BBMRI-ERIC structure. Among all 13 analyzed areas, 27 deviations were identified. Eleven of them were implemented in all audited biobanks but defined as the areas for improvement, 16 of them were not implemented correctly or not implemented at all, respectively (areas underlined to corrective procedures).

Bacteria of the genus Proteus of the family Enterobacteriaceae are facultative human pathogens responsible mainly for urinary tract and wound infections, bacteremia and the development of rheumatoid arthritis (RA). We have analyzed and compared by ELISA the titer of antibodies in plasmas of healthy individuals and in sera of rheumatoid arthritis patients recognizing a potential host cross-reactive epitope (lysine-galacturonic acid epitopes) present in Proteus lipopolysaccharide (LPS). In our experiments LPSs isolated from two mutants of smooth Proteus mirabilis 1959 (O3), i.e. strains R110 and R45, were used. R110 (Ra type mutant) is lacking the O-specific polysaccharide, but possesses a complete core oligosaccharide, while R45 (Re type) has a reduced core oligosaccharide and contains two 3-deoxy-d-manno-oct-2-ulosonic acid residues and one of 4-amino-4-deoxy-l-arabinopyranose residues. Titer of P. mirabilis S1959 LPS-specific-antibodies increased with the age of blood donors. RA and blood donors’ sera contained antibodies against S and Ra and Re type of P. mirabilis O3 LPSs. Antibodies recognizing lysine-galacturonic acid epitopes of O3 LPS were detected by ELISA in some plasmas of healthy individuals and sera of rheumatoid arthritis patients. RA patients antibodies reacting with P. mirabilis S1959 S and R LPSs may indicate a potential role of anti-LPS antibodies in molecular mimicry in RA diseases.

In 2017, Polish Biobanking Network was established in Poland, within BBMRI.pl project titled “Organization of Polish Biobanking Network within the Biobanking and Biomolecular Resources Research Infrastructure BBMRI-ERIC” as a strategic scientific infrastructure concept. One of the key elements of the project was the verification of the current status of QMS in the Polish biobanking institutions and the implementation of common solutions. The main goal was to indicate the current QMS level and determine the starting points for QMS development for each biobank of the Polish Biobanking Network (PBN). Within 3 years, 35 audit visits were performed. The current status and the level of QMS implementation in each biobank were assessed. Five hundred and seventy recommendations were prepared. The data was analyzed using Fischer Exact test to determine whether or not a significant association was observed. Three areas of analysis were covered: (1) BBMRI.pl status, (2) QMS implementation level and (3) private/public party, respectively. The results were discussed within 15 areas. Concluding remarks showed that some differences were observed in the case of subgroups analysis. There is convergence in QMS within the biobanks where Tissue Banks are located. Moreover, some discrepancies between the QMS implementation level in BBMRI.pl Consortium biobanks and PBN biobanks are observed. Nevertheless, the consortium members are obliged to prepare other biobanks willing to enter the PBN as Members/Observers or which already are in the PBN, so that they can meet the requirements of the quality management system that will enable efficient management of biobanking processes in these units. That is why some actions within BBMRI.pl projects are organized to help the whole biobanking community in Poland implement the harmonized solution.
