ABSTRACT

BACKGROUND@#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.

ABSTRACT

OBJECTIVE@#To analyze the distribution and drug resistance of pathogens sampled from the patients with bloodstream infection in the department of hematology of PLA General Hospital, so as to provide evidences for clinical prevention and control infection.@*METHODS@#From January 2014 to December 2017, A total of 286 cases-time positive blood culture samples from 212 patients in the department of hematology of the General Hospital of Chinese PLA were collected. The clinical characteristics of patients and the distribution and drug resistance of pathogens were analyzed retrospectively.@*RESULTS@#182(63.64%) bacterial strains were Gram-negative, and the other 104(36.36%) were Gram-positive. There were 88 strains of Escherichia coli(30.77%), 34 strains of Pseudomonas aeruginosa(11.89%), 26 strains of Klebsiella pneumoniae(9.09%), 25 strains of Staphylococcus epidermidis(8.74%), 20 strains of Gram-positive rods(6.99%), 16 strains of Staphylococcus hominis(5.59%), 11 strains of Etaphylococcus haemolyticus(3.85%), 10 strains of Staphylococcus aureus(3.50%), 6 strains of Staphylococcus capitis(2.10%), 5 strains of Acinetobacter baumannii(1.75%) and so on. Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae as Gram-negative bacteria were sensitive to amikacin. Staphylococcus epidermidis and Staphylococcus aureus as Gram-positive bacteria were sensitive to vancomycin and nitrofurantoin.@*CONCLUSION@#The blood culture patients with bloodstream infection in department of hematology of our hospital confirmed that more infections are Gram-negative. The clinicians should choose suitable antibiotics according to the results of bacterial culture and drug sensitive test.
