Infection constitutes a leading cause of morbidity and mortality in hemodialysis (HD) patients. The type of vascular access is an important determinant of the risk of infection. Therefore, identification of risk factors leading to catheter-related bacteremia (CRB) is strongly required. The aim of this prospective large cohort study of HD patients using only catheters as vascular access was to isolate risk factors for CRB. ⋯ Reducing CRB is still a challenge for nephrologists to reduce patient morbidity and mortality. Our study could demonstrate that diabetes, previous history of CRB, site of catheter implantation and duration of catheter use were the most important risk factors for bacteremia. Therefore, to prevent CRB, particular attention should be paid to patients with diabetes and a previous history of bacteremia following strict hygienic and aseptic rules for catheter handling associated with the regular use of antiseptic lock solutions.

Achieving normohydration remains a non-trivial issue in haemodialysis therapy. Preventing the deleterious effects of fluid overload and dehydration is difficult to achieve. Objective and clinically applicable methods for the determination of a target representing normohydration are needed. ⋯ Whole-body bioimpedance spectroscopy in combination with a physiologic tissue model provides for the first time an objective and relevant target for clinical dry weight assessment.
