    ObjectiveTo investigate the protective effect and possible mechanisms of vitamin B6 against renal injury in patients with sepsis.MethodsA total of 128 patients with sepsis who met the entry criteria in multiple centres were randomly divided into experimental (intravenous vitamin B6 therapy) and control (intravenous 0.9% sodium chloride therapy) groups based on usual care. Clinical data, the inflammatory response indicators interleukin 6 (IL-6), interleukin 8 (IL-8), tumour necrosis factor (TNF-α) and endothelin-1 (ET-1), the oxidative stress response indicators superoxide dismutase, glutathione and malondialdehyde, and renal function (assessed by blood urea nitrogen [BUN], serum creatinine [SCr] and renal resistance index [RRI] monitored by ultrasound) were compared between the two groups.ResultsAfter 7 d of treatment, the IL-6, IL-8, TNF-α and ET-1 levels in the experimental group were significantly lower than those in the control group, the oxidative stress response indicators were significantly improved in the experimental group and the BUN, SCr and RRI values in the experimental group were significantly lower than those in the control group (p < 0.05). There was no statistical difference between the two groups in the rate of renal replacement therapy and 28 d mortality (p > 0.05). However, the ICU length of stay and the total hospitalisation expenses in the experimental group were significantly lower than those in the control group (p < 0.05).ConclusionThe administration of vitamin B6 in the treatment of patients with sepsis attenuates renal injury, and the mechanism may be related to pyridoxine decreasing the levels of inflammatory mediators and their regulation by redox stress.Clinical trial registration: ClinicalTrials.gov Identifier: NCT06008223.Copyright © 2024 by the Shock Society.
