Bone marrow transplantation 59(3) 325-333 2024年3月Various complications can influence hematopoietic cell transplantation (HCT) outcomes. Renal complications can occur during the early to late phases of HCT along with various factors. However, studies focusing on fatal renal complications (FRCs) are scarce. Herein, we analyzed 36,596 first allogeneic HCT recipients retrospectively. Overall, 782 patients died of FRCs at a median of 108 (range, 0-3,440) days after HCT. The cumulative incidence of FRCs was 1.7% and 2.2% at one and five years, respectively. FRCs were associated with older age, male sex, non-complete remission (non-CR), lower performance status (PS), and HCT comorbidity index (HCT-CI) associated with renal comorbidity in multivariate analysis. The risk factors within 100 days included older age, multiple myeloma, PS, and HCT-CI comorbidities (psychiatric disturbance, hepatic disease, obesity, and renal disease). Older age and male sex were risk factors between 100 days and one year. After one year, HCT-CI was associated with the presence of diabetes and prior solid tumor; total body irradiation was identified as a risk factor. Non-CR was a common risk factor in all three phases. Furthermore, acute and chronic graft-versus-host disease, reactivation of cytomegalovirus, and relapse of underlying disease also affected FRCs. Systematic follow-up may be necessary based on the patients' risk factors and post-HCT events.

Transplantation proceedings 2024年2月8日BACKGROUND: As the Japanese population may have less genetic diversity than other ethnic groups, treatment outcomes may be affected when allogeneic hematopoietic cell transplantation is performed in other races. However, evidence explaining the effect of racial differences is limited. METHODS: We used the Japanese National Database to examine the outcomes of first allogeneic bone marrow transplantations (BMTs) performed between Japanese and non-Japanese patients from 1996 to 2021. We performed propensity score matching using sex, age group, underlying disease group, HLA mismatch, conditioning regimen intensity, and BMT implementation age to select Japanese-to-Japanese BMT patients as the controls. RESULTS: The numbers of non-Japanese-to-Japanese and Japanese-to-non-Japanese BMT cases included in the analysis were 48 and 75, respectively, and the following outcomes were compared: overall survival, non-relapse mortality, acute graft-vs-host disease (GVHD) ≥ grade II, chronic GVHD, and engraftment of neutrophils and platelets. Most parameters did not differ when comparing BMTs according to ethnicity; only platelet engraftment was delayed in Japanese-to-non-Japanese BMT but not in non-Japanese-to-Japanese BMT. CONCLUSIONS: The results of this study suggested that BMT performed in Japanese and non-Japanese patients has little effect on treatment outcomes. The results of this study may be useful for donor selection in Japan, where internationalization has progressed in recent years.

American journal of hematology 99(2) 263-273 2024年2月We retrospectively evaluated the effect of 17 individual comorbidities, defined by the hematopoietic cell transplantation (HCT)-specific comorbidity index, on non-relapse mortality (NRM) and overall survival (OS) in 9531 patients aged between 16 and 70 years who underwent their first allogeneic HCT from 8/8 and 7/8 allele-matched unrelated donors (8/8 and 7/8 MUDs) or single-unit unrelated cord blood (UCB) between 2011 and 2020 using data from a Japanese registry database. In the multivariate analysis, infection (adjusted hazard ratio [HR], 1.62, 95% confidence interval [CI], 1.33-1.99 for 8/8 and 7/8 MUDs; adjusted HR, 1.33, 95%CI, 1.12-1.58 for UCB) and moderate/severe hepatic comorbidity (adjusted HR, 1.57, 95%CI, 1.04-2.38 for 8/8 and 7/8 MUDs; adjusted HR, 1.53, 95%CI, 1.09-2.15 for UCB) had a significant impact on NRM in both donor groups. Cardiac comorbidity (adjusted HR, 1.40, 95%CI, 1.08-1.80), mild hepatic comorbidity (adjusted HR, 1.22, 95%CI, 1.01-1.48), rheumatologic comorbidity (adjusted HR, 1.67, 95%CI, 1.11-2.51), renal comorbidity (adjusted HR, 2.44, 95%CI, 1.46-4.09), and severe pulmonary comorbidity (adjusted HR, 1.40, 95%CI, 1.11-1.77) were significantly associated with an increased risk of NRM but only in UCB recipients. Renal comorbidity had the strongest impact on poor OS in both donor groups (adjusted HR, 1.73, 95%CI, 1.10-2.72 for 8/8 and 7/8 MUDs; adjusted HR, 2.24, 95%CI, 1.54-3.24 for UCB). Therefore, unrelated donor selection should be taken into consideration along with the presence of specific comorbidities, such as cardiac, rheumatologic, renal, mild hepatic, and severe pulmonary comorbidities.

Blood advances 2024年1月1日Higher rate of non-relapse mortality (NRM) remains yet to be resolved in umbilical cord blood transplantation (UCBT). Considering that UCBT has some unique features compared with allogeneic hematopoietic cell transplantation from other graft sources, a UCBT-specific NRM risk assessment system is required. Thus, in this study, we sought to develop a UCBT-specific NRM Risk Assessment (CoBRA) score. Using a nationwide registry database, we retrospectively analyzed 4437 recipients who had received their first single-unit UCBT. Using the backward elimination method, we constructed the CoBRA score in a training cohort (n = 2687), which consisted of recipients age ≥ 55 (score 2), hematopoietic cell transplantation-specific comorbidity index (HCT-CI) ≥ 3 (score 2), male recipient, graft-versus-host disease (GVHD) prophylaxis other than tacrolimus in combination with methotrexate, performance status (PS) 2-4, HLA allele mismatch ≥ 2, refined disease risk index (DRI) high-risk, myeloablative conditioning (MAC), and CD34+ cell doses < 0.82 x 105/kg (score 1 in each). The recipients were categorized into three groups: Low (0-4 points), Intermediate (5-7 points), and High (8-11 points) groups according to the CoBRA score. In the validation cohort (n = 1750), the cumulative incidence of NRM at 2 years was 14.9%, 25.5%, and 47.1% (P < 0.001), and 2-year overall survival (OS) was 74.2%, 52.7%, and 26.3% (P < 0.001) in the Low, Intermediate, and High groups, respectively. In summary, the CoBRA score could predict the NRM risk as well as OS after UCBT. Further external validation will be needed to confirm the significance of the CoBRA score.
