Abstract | BACKGROUND: Leukocyte reduction filters are widely used for platelet transfusion therapy, and effective leukocyte removal is mandatory for transfusion safety. We evaluated both the performance of leukocyte reduction filters for platelets and the effect of filtration on platelet function. METHODS: A total of 100 pooled products (eight platelet concentrates were randomly pooled for each product) were used in this study: 50 were filtered by BioP-plus (Fresenius Kabi AG, Homburg, Germany) and 50 by PXL-8 (Pall Corporation, East Hills, NY, USA). Leukocyte reduction, platelet recovery, and filtration time were evaluated in each leukocyte reduction filter. Platelet aggregation responses to thrombin receptor activation peptide stimulation were compared in pre- and post-filtration products using impedance aggregometry (Multiplate Analyzer, Dynabyte Medical, Munich, Germany). RESULTS: Leukocyte counts were uniformly less than 8.3×10(5) in all the post-filtration products, except one filtered by the PXL-8. Leukocyte reduction was 99.1% for BioP-plus and 99.7% for PXL-8, and platelet recovery was 84.2% for the BioP-plus and 86.7% for PXL-8. Filtration time of the BioP-plus was significantly shorter than that of PXL-8. Post-filtration platelet aggregation tended to decrease in both filters, showing no difference between them. CONCLUSIONS: Both BioP-plus and PXL-8 leukocyte reduction filters for platelets performed well with effective leukocyte reduction and satisfactory platelet recovery. Although platelet function was decreased after filtration procedures, its clinical relevance is uncertain. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
