Annual Report The Norwegian Bone Marrow Donor Registry
ANNUAL REPORT THE NORWEGIAN BONE MARROW DONOR REGISTRY The Norwegian Bone Marrow Donor Registry (NBMDR) was established in 199 at the Institute of Immunology (previously Institute of Transplantation Immunology), Rikshospitalet Medical Centre, Oslo, after a generous donation from The Norwegian Cancer Society. This society has been the main source of financial support since the establishment. We are very grateful for the continuous support. The aim of NBMDR is to provide stem cells from an HLA identical unrelated donor to domestic and international patients in need of an allogeneic stem cell transplantation. The patients suffer from malignant blood disorders as well as other severe blood diseases, metabolic diseases, and immunodeficiencies in children. NBMDR is part of an extensive international collaboration, representing more than 11 mills. HLA-typed volunteer donors and umbilical cord blood units listed in Bone Marrow Donors Worldwide (BMDW). 244 Norwegian patients have since 199 been transplanted with stem cells from Norwegian (32) and international donor (212). In addition, NBMDR has provided stem cells to 238 patients abroad. NBMDR and international relations NBMDR is a member of the World Marrow Donor Association (WMDA). NBMDR regularly submits donor HLA files to BMDW. National Marrow Donor Program (NMDP), the largest US donor registry, accredited Rikshospitalet Medical Centre as a transplant centre in and as a collection centre in. NBMDR was accredited as a donor centre in. In the fall of, a formal collaboration with the Blood Bank in Reykjavik, Iceland, was established where Icelandic donors are recruited in the Blood Bank and are HLA typed in Reykjavik and Oslo as part of a joint HLA typing effort. HLA typing of donors The Institute of Immunology, which is accredited by European Federation of Immunogenetics (EFI), performs HLA typing for NBMDR. In addition, Icelandic donors are also typed at the Blood Bank in Reykjavik, Iceland, as part of the joint typing effort. By December 31,, 25,169 HLA-A and -B-typed active donors were in NBMDR. 24,76 (95.7%) were also HLA-DR typed, mostly by genomic low or intermediate resolution typing techniques. 176 donors were withdrawn in due to high age (134) or other reasons (42). Search in and donation by NBMDR NBMDR received donor search requests for 4,373 patients in. 41 donors were evaluated for 327 patients with further HLA-typing or confirmatory testing (CT). 27 NBMDR donors donated bone marrow or peripheral blood stem cells (PBSC) in (first donation). One donor donated a second time to the same recipient. Lymphocytes for post-transplant donor lymphocyte infusion (DLI) were donated three times in. By the end of, 27 patients (32 domestic and 238 international patients) have received bone marrow or PBSC from Norwegian donors.14 donors have donated twice to the same recipient and 9 donors have donated twice to different recipients. In, 27 Norwegian donors donated bone marrow (9) or PBSC (18) to patients in USA (9), Norway (7), Germany (2), Sweden (2), Austria (1), Brazil (1), Canada (1), France (1), Poland (1), Russia (1) and Switzerland (1). In addition, one Norwegian donor re-donated PBSC to a patient. - 2 -
Search for donors for Norwegian patients In, search requests for 36 new Norwegian patients were made to NBMDR and to registries and cord blood banks around the world. The data file of BMDW is always checked for every search initiated, and it is repeatedly used in an attempt to find a donor for every patient for whom a donor has not been identified. Transplantation with an unrelated HLA matched donor or cord blood has been performed on an average for 59% of the patients for whom an unrelated donor search was initiated. Since, we have found an HLA match donor for 85% of the patients searched for. In, 24 Norwegian patients were transplanted with bone marrow (19) or PBSC (5) from an unrelated HLA matched donor from Norway (7), USA (6), Germany (4), Great Britain (4), Finland (1), France (1) and Wales (1). In addition, one patient was transplanted with a cord blood unit from the US. By the end of, 244 Norwegian patients have since 199 been transplanted with stem cells from an unrelated donor or cord blood. NBMDR and blood banks NBMDR donors are recruited from blood banks throughout the country. Since the fall of, Icelandic donors are also recruited in the Blood Bank of Reykjavik, Iceland. These donors are added to the donor pool of NBMDR. In addition to running the donor registry, NBMDR also performs donor searches for Norwegian patients. The annual course for personnel from all blood banks in Norway was arranged in January of. One newsletter was mailed to all blood banks in. In addition, the large blood banks (Bergen, Oslo, Tromsø, Trondheim and Iceland) have access to a program for searching for HLA-compatible platelet donors among their own blood donors. All blood banks continue to recruit new donors. NBMDR is very grateful to the blood banks their effort is crucial to NBMDR.

Gunnar Kvalheim, MD, PhD, Dept. of Cellular Therapy, Radiumhospitalet Med. Centre In addition, medical doctors at the Section of Blood Diseases and Dept. of Cellular Therapy conducted donor information sessions and health examinations for Norwegian donors who were selected for bone marrow or PBSC donation. Anne-Grethe Fjellman coordinated the collaboration with the transplant physicians at Section of Blood Diseases, and Merete Djupedal coordinated the collection of bone marrow, PBSC and lymphocyte collections at the Department of Cellular Therapy. HLA-typing of donors All new donors are typed for HLA-A, -B, -C and -DRB1 by SSO technique. SSP typing is performed if the initial typing is inconclusive. Upon request, NBMDR performs low and high resolution genomic typing for A, B, C, DRB1, DRB3, DRB4, DRB5, DQB1, and DPB1. - 3 -

Annual and accumulated number of new donors and number of active donors by the end of. All donors are recruited from blood banks throughout the country and (after the fall of ) from Iceland. The yellow bars are shorter than the blue bars. This is because a certain fraction of the donors have been removed as time has passed, due to high age or other reasons. 16 12 8 4 1989 199 22 SEARCH FOR DONORS IN NMBDR 4 35 Annual number Accumulated number Fig. 2.

SEARCH FOR DONORS FOR NORWEGIAN PATIENTS In, Institute of Immunology initiated search for 36 Norwegian patients in NBMDR and other registries. By the end of the year, 13 of these patients had been transplanted with an HLA matched unrelated donor or cord blood, and more are awaiting transplantation in 27 (table 2). Table 2 provides the number of donor searches and transplantation for Norwegian patients. By the end of, a total number of 244 Norwegian patients had been transplanted with an unrelated donor or cord blood. 6-75% of the patients for whom a donor search was initiated have been transplanted. Since, HLA matched donors have been found for 85-95% of the patients, but not all patients have been transplanted for various reasons (donors found in the extended family, the patient's treatment protocol was changed, cord blood units not indicated for all patients, the patient died etc). The donors who have donated stem cells to Norwegian patients by the end of came from 2 different countries (fig. 13). Table 2. Annual number of Norwegian patients for whom a donor search was initiated and the number of patients who were transplanted. The number of donors and cord blood units listed in Bone Marrow Donors Worldwide (BMDW) at the end of each year is also given as well as the relative number of patients with at least one donor or cord blood unit identified.

Thus, the relative number of transplantations during the last few years remains to be increased by transplantations that take place in 27 or later. **Not all patients for whom a search was initiated were in the end actually in the need of an unrelated donor transplantation, e.g. haploidentical donors in the extended family were eventually identified or the patient's treatment protocol was re-evaluated. These patients have not been excluded from this table. na: not assessed - 11 -
