Abstract
Objective: Sepsis-related uncontrolled systemic inflammation may trigger necroptosis, which is correlated with receptor-interacting protein kinase 3 (RIPK3) level. A high level of RIPK3 is associated with organ dysfunction and thus, mortality. This study aimed to analyze the ability of RIPK3 level to predict mortality in septic patients.
Design: This was a prospective cohort study.
Setting: This study was conducted in intensive care unit from February until August 2019.
Patients and participants: This study included patients aged 18 years or more who met the Sepsis-3 definition. Baseline demographic data were measured.
Interventions: Blood was collected to measure RIPK3 at sepsis recognition. RIPK3 level was measured using enzyme-linked immunosorbent assay using Bio-Rad (Bio-Rad Laboratories, California, US). Hour-1 bundle resuscitation was performed on all participants. Participants were observed for 28 days for mortality. Data were analyzed using STATA program software.
Measurement and results: A total of 59 subjects were analyzed. The cutoff point of RIPK3 level was 0.51 ng/ml with 92.5% sensitivity and 89.5% specificity in predicting mortality. RIPK3 level has an excellent performance with area under the receiver operating characteristic (ROC) curve (AUC) value of 0.925.
Conclusions: RIPK3 level can be considered a useful tool to recognize high risk mortality among critically septic patients.
