简介：AbstractBackground:The impacts of previous cardio-cerebrovascular disease (pre-CCVD) on the outcomes of hematopoietic cell transplantation (HCT) are not well described. Patients with pre-CCVD may often be poor candidates for HCT. This study aimed to investigate the impact of pre-CCVD on transplant outcomes.Methods:A retrospective study was conducted between patients with and without pre-CCVD who consecutively received allogeneic or autologous HCT between November 2013 and January 2020 with a matching of age and disease status. The cardiovascular complications and HCT outcomes of the two groups were evaluated and compared. The primary endpoints were post-transplant cardio-cerebrovascular disease (post-CCVD) and non-relapse mortality (NRM). We used a multivariable Cox proportional hazard model and the Fine-Gray competing risk regressions for analyses to estimate the hazard ratios (HRs).Results:The outcomes of 23 HCT recipients with pre-CCVD were compared with those of 107 patients in the control group. No significant differences were noted in terms of engraftment, overall survival (OS) (67.00% vs. 67.90%, P = 0.983), or relapse (29.78% vs. 28.26%, P = 0.561) between the pre-CCVD group and the control group. The cumulative incidences of 2-year NRM were similar between patients with pre-CCVD and the controls (14.68% vs. 17.08%, P = 0.670). However, pre-CCVD was associated with an increased incidence of post-CCVD (HR: 12.50, 95% confidence interval [CI]: 3.88-40.30, P < 0.001), which was an independent risk factor for increased NRM (HR: 10.29, 95% CI: 3.84-27.62, P < 0.001) and inferior OS (HR: 10.29, 95% CI: 3.84-27.62, P < 0.001).Conclusions:These findings suggest that the existence of pre-CCVD before transplantation might not result in increased mortality directly but superpose the toxicity of the transplantation procedure, leading to a risk of post-CCVD. Post-CCVD was a powerful predictor for high NRM and inferior OS. Further risk stratification of pre-CCVD is needed to reduce NRM in various transplantation settings.

简介：AbstractBackground:Regulated upon activation, normal T-cell expressed, and secreted (RANTES) is a chemokine actively involved in the initiation and progression of atherosclerosis (AS), which is the major cause of ischemic cerebrovascular disease (ICVD). This study aimed to determine the associations between circulating RANTES level and overall AS conditions of cardiac and cerebral vessel beds in patients with ICVD.Methods:Patients with ICVD admitted to the department of neurology of Xuanwu Hospital from April 1, 2019 to June 30, 2019 were prospectively enrolled in the study. Plasma RANTES level was measured by enzyme-linked immunosorbent assay to represent the circulating RANTES level. The integrated AS burden of the cervicocephalic and coronary arteries was examined using computed tomography angiography and reflected by "cardio-cerebral AS burden (CCAB)" as a continuous variable. Then, the relationship of plasma RANTES level and CCAB in patients with ICVD was analyzed by correlation analyses and general linear models.Results:A total of 40 patients with ICVD were included in the study. There was a significant positive correlation between CCAB and plasma RANTES level in ICVD (r = 0.786, P < 0.001), independent of age, sex, acute or chronic phase of ICVD, and mono or dual antiplatelet therapy (adjusted B for ln RANTES, 12.063; 95% confidence interval, 7.572-16.533). The association of plasma RANTES level with AS conditions (burden, severity, and extent) in single cardiac or cerebral vessel bed was similar to that with CCAB, but the correlation coefficient for CCAB was higher (increment ranged from 0.126 to 0.397).Conclusions:Plasma RANTES level was an independent indicator for the integrated AS burden of the cervicocephalic and coronary arteries in ICVD. Comprehensive evaluation of AS conditions using the novel continuous index CCAB might be important in revealing the systematic relationship between circulating RANTES and AS in patients with ICVD.
