BackgroundSeptic shock is a leading cause of acute kidney injury (AKI). Endotoxins and cytokine levels are associated with the occurrence and severity of AKI, and different blood purification devices are available to remove them from circulation. One such device, oXiris, is a hollow-fibre purification filter that clears both endotoxins and cytokines. Due to limited evidence, clinical use of this device is not currently advocated in guidelines. However, clinics do regularly use this device, and there is a critical need for guidance on the application of it in sepsis with and without AKI.MethodA modified Delphi-based method was used to collate -European experts' views on the indication(s), initiation and discontinuation criteria and success measures for oXiris.ResultsA panel of 14 participants was selected based on known clinical expertise in the areas of critical care and sepsis management, as well as their experience of using the oXiris blood purification device. The participants used different criteria to initiate treatment with oXiris in sepsis patients with and without AKI. Septic shock with AKI was the priority patient population, with oXiris used to rapidly improve haemodynamic parameters. Achieving haemodynamic stability within 72 h was a key factor for determining treatment success.ConclusionIn the absence of established guidelines, users of hollow-fibre purification devices such as oXiris may benefit from standardised approaches to selecting patients and initiating and terminating treatment, as well as measuring success. Further evidence in the form of randomised clinical trials is urgently required.© 2019 The Author(s) Published by S. Karger AG, Basel.
