RESUMEN
OBJECTIVES: Chlorhexidine gluconate (CHG)-coated gel pad dressings for central venous catheter (CVC) may prevent CVC-related bloodstream infections (CRBSI). However, real-world data showing beneficial effects in patients with hematologic malignancies are scarce. METHODS: In a matched-pair analysis with data from a multicenter CVC registry, non-tunneled jugular and subclavian vein CVC in adults with hematologic malignancies or germ cell tumors (including patients receiving autologous hematopoietic stem cell transplantation [ASCT]) with CHG were compared with non-CHG dressings. The primary endpoint was definite CRBSI rate within 14 days (dCRBSI14) of CVC insertion; secondary endpoints were combined rate of definite or probable CRBSI within 14 days (dpCRBSI14), overall (dpCRBSI), and CRBSI incidences of all estimates. RESULTS: In total, 2070 CVCs were assessed. There was no statistically significant difference in dCRBSI14 (2.3% vs. 3.5%) between patients with and without CHG gel dressings. Likewise, with regards to dpCRBSI14 (6.2% vs. 6.3%) and the overall dpCRBSI rate (9.2% vs. 10.5%), no significant difference was detected. Furthermore, dCRBSI14 incidence (2.0 vs. 3.2/1000 CVC days), dpCRBSI14 incidence (5.4 vs. 5.6/1000 CVC days), and overall CRBSI incidence (5.5 vs. 6.0/1000 CVC days) showed no significant differences. CONCLUSIONS: CRBSI rates were not reduced by the use of CHG gel dressings in patients with hematologic malignancies and/or ASCT.

PURPOSE: Overall, insertion of central venous catheter (CVC) into femoral veins (FV) has been shown to be associated with a higher risk of infection compared with subclavian and internal jugular (IJV/SCV) CVC, but no data are available on the impact of the FV insertion site on the CVC-related bloodstream infections (CRBSI) risk in patients with cancer. The objective of the study is to compare CRBSI rates and incidences of FV with those of internal jugular and subclavian vein (IJV/SCV CVC) as observed in the prospective SECRECY registry. METHODS: SECRECY is an ongoing observational, prospective, clinical CRBSI registry active in six departments of hematology/oncology in Germany. Each case of FV CVC was matched at a ratio of 1:1 to a case with IJV/SCV CVC. The propensity score was estimated using a multivariable logistic regression model adjusting for age, sex, cancer type, and duration of indwelling catheter. RESULTS: Of 4268 CVCs included in this analysis, 52 (1.2%) were inserted into the FV and 4216 (98.8%) into the IJV/SCV. 52 cases of FV CVC were matched with 52 IJV/SCV CVC. There was no significant difference in the CRBSI rate (3.8% vs. 9.6%), the CRBSI incidence (5.7 vs. 14.2/1000 CVC days), and the median CVC time (5.5 vs. 5 days) between the FV and the IJV/SCV group. CONCLUSION: Based on this data, inserting FV CVCs in patients with cancer does, at least in the short-term, not appear to be associated with an increased risk of CRBSI as compared to IJV/SCV CVC.

OBJECTIVES: Efficacy and safety of letermovir as prophylaxis for clinically significant cytomegalovirus infections (csCVMi) was evaluated in randomised controlled trials while most of the real-world studies are single-centre experiences. METHODS: We performed a retrospective, multi-centre case-control study at six German university hospitals to evaluate clinical experiences in patients receiving CMV prophylaxis with letermovir (n = 200) compared to controls without CMV prophylaxis (n = 200) during a 48-week follow-up period after allogeneic hematopoietic cell transplantation (aHCT). RESULTS: The incidence of csCMVi after aHCT was significantly reduced in the letermovir (34%, n = 68) compared to the control group (56%, n = 112; p < 0.001). Letermovir as CMV prophylaxis (OR 0.362) was found to be the only independent variable associated with the prevention of csCMVi. Patients receiving letermovir showed significantly better survival compared to the control group (HR = 1.735, 95% CI: 1.111-2.712; p = 0.014). Of all csCMVi, 46% (n = 31) occurred after discontinuation of letermovir prophylaxis. Severe neutropenia (<500 neutrophils/µL) on the day of the stem cell infusion was the only independent variable for an increased risk of csCMVi after the end of letermovir prophylaxis. CONCLUSIONS: Our study highlights the preventive effects of letermovir on csCMVi after aHCT. A substantial proportion of patients developed a csCMVi after discontinuation of letermovir. In particular, patients with severe neutropenia require specific attention after drug discontinuation.
