A total of 40,444 allogeneic HSCT cases in Japan between 2011 and 2021 were examined using an interrupted time series analysis to assess the impact of COVID-19 on CBT utilization. Following the SARS-CoV-2 pandemic, CBT cases demonstrated a significant increase (11.06 [95% confidence interval (CI): 1.87 to 20.25] cases per month), whereas bone marrow transplantation cases decreased, by 10.74 cases per month (95% CI, -19.84 to -1.63 cases per month). Total HSCT cases remained stable with a level change of 5.47 cases per month (95% CI, -10.07 to 21.01 cases per month) and a trend change of -1.11 cases per month (95% CI, -2.22 to 0.004 cases per month).

But data to support this recommendation are poor. The aim of this monocentric study was to compare retrospectively the use of fluconazole (n = 96) vs. posaconazole (n = 63), as primary antifungal prophylaxis within the first 90 days (D) post-transplant in a cohort of patients at HR-IFI (n = 159). HR-IFI was defined by the use of an alternative donor, post-transplant cyclophosphamide and/or sequential conditioning regimen, and/or an active disease at transplant or a previous allo-HSCT. Incidences of D90, 6-month, 1-year and 2-year CI of IFI as well as D90 primary prophylaxis failure (IFI resulting in the initiation of a curative antifungal therapy or a permanent discontinuation of the prophylaxis for toxicity) were similar between both groups. However, the number of probable/proven IFI that occurred between D0 and D90 was the double in the fluco group (9 vs. 4). Also, no proven IFI (vs. 4) or mucormycoses (vs. 1) or IFI related death (vs. 4) occurred in the posa group in the first 90 days. Posaconazole thus appears to be a good option to prevent IFI after allo-HSCT in patients at HR-IFI.</p>","PeriodicalId":9126,"journal":{"name":"Bone Marrow Transplantation","volume":" ","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143972080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
