New global reporting system for serious (product) events and adverse reactions in hematopoietic stem cell donation and transplantation.

Annually more than 21,000 volunteer unrelated hematopoietic stem cell donations are performed worldwide for patients with life-threatening diseases such as acute leukaemia. Donor safety issues and donor protection is one of the top priorities for the international cooperation of unrelated hematopoietic stem cell donor registries represented by the World Marrow Donor Association (WMDA). With this new global reporting system for serious events and adverse reactions (S(P)EARs), the WMDA aims to become the global leading online platform for hematopoietic stem cell donor organisations to report their S(P)EARs from both unrelated and family donors. Software developer Cogapp developed the platform using a Knack environment based on requirements of experienced reporters and reviewers. On July 1st WMDA launched a robust online reporting system for S(P)EARs in order to provide accurate information about potential risks to donors. The collected data about S(P)EARs occurring in donors will be analysed and used to provide statistics on the type of reports being submitted and to put in place best practices to mitigate such effects and occurrences. Via the annual S(P)EAR reports the results will be disseminated worldwide.

Impact of selection of cord blood units from the United States and swiss registries on the cost of banking operations.

BACKGROUND: Over the last 2 decades, cord blood (CB) has become an important source of blood stem cells. Clinical experience has shown that CB is a viable source for blood stem cells in the field of unrelated hematopoietic blood stem cell transplantation. METHODS: Studies of CB units (CBUs) stored and ordered from the US (National Marrow Donor Program (NMDP) and Swiss (Swiss Blood Stem Cells (SBSQ)) CB registries were conducted to assess whether these CBUs met the needs of transplantation patients, as evidenced by units being selected for transplantation. These data were compared to international banking and selection data (Bone Marrow Donors Worldwide (BMDW), World Marrow Donor Association (WMDA)). Further analysis was conducted on whether current CB banking practices were economically viable given the units being selected from the registries for transplant. It should be mentioned that our analysis focused on usage, deliberately omitting any information about clinical outcomes of CB transplantation. RESULTS: A disproportionate number of units with high total nucleated cell (TNC) counts are selected, compared to the distribution of units by TNC available. Therefore, the decision to use a low threshold for banking purposes cannot be supported by economic analysis and may limit the economic viability of future public CB banking. CONCLUSIONS: We suggest significantly raising the TNC level used to determine a bankable unit. A level of 125 × 10(7) TNCs, maybe even 150 × 10(7) TNCs, might be a viable banking threshold. This would improve the return on inventory investments while meeting transplantation needs based on current selection criteria.

"Worldwide Network for Blood & Marrow Transplantation (WBMT) special article, challenges facing emerging alternate donor registries".

Hematopoietic cell transplantation (HCT) activity is increasing at an unprecedented pace with > 50,000 allogeneic transplants occurring annually worldwide. Establishing a functional HCT donor registry can be very challenging with respect to ethnicities, financial, technical, and geopolitical issues. Extensive planning steps are essential to overcome the expected challenges while establishing the registry, and to maintain its functionality. A few strategies can help move past those challenges and push the development of such registries forward. Authorities involved in HCT donor registry establishment will have to balance the advantages and costs of such a project and accommodate the emerging alternatives such as cord blood or related haploidentical transplants. Miscalculations and incomplete understanding of the various aspects of the process can have tremendous impact on the optimization of a HCT donor registry especially in developing countries. Herein we present some challenges in establishing such a registry and present potential solutions.

One million haemopoietic stem-cell transplants: a retrospective observational study.

BACKGROUND: The transplantation of cells, tissues, and organs has been recognised by WHO as an important medical task for its member states; however, information about how to best organise transplantation is scarce. We aimed to document the activity worldwide from the beginning of transplantation and search for region adapted indications and associations between transplant rates and macroeconomics. METHODS: Between Jan 1, 2006, and Dec 31, 2014, the Worldwide Network for Blood and Marrow Transplantation collected data for the evolution of haemopoietic stem-cell transplantation (HSCT) activity and volunteer donors in the 194 WHO member states. FINDINGS: 953,651 HSCTs (553,350 [58%] autologous and 400,301 [42%] allogeneic) were reported by 1516 transplant centres from 75 countries. No transplants were done in countries with fewer than 300,000 inhabitants, a surface area less than 700 km(2), and a gross national income per person of US$1260 or lower. Use of HSCT increased from the first transplant in 1957 to almost 10,000 by 1985. We recorded a cumulative total of about 100,000 transplants by 1995, and an estimated 1 million by December, 2012. Unrelated donor registries contributed 22·3 million typed volunteer donors and 645,646 cord blood products by 2012. Numbers of allogeneic HSCTs increased in the past 35 years with no signs of saturation (R(2)=0·989). Transplant rates were higher in countries with more resources, more transplant teams, and an unrelated donor infrastructure. INTERPRETATION: Our findings show achievements and high unmet needs and give guidance for decisions; to grant access for patients, to provide a donor infrastructure, and to limit overuse by defining risk and region adapted indications for HSCT as an efficient and cost-effective approach for life-threatening, potentially curable diseases. FUNDING: Funding for this study was indirectly provided by support of the WBMT.
