Rasio Laktat/Albumin sebagai Prediktor Mortalitas pada Pasien dengan Sepsis dan Syok Sepsis: Studi Meta-Analisis

Abstract

Introduction. The lactate/albumin ratio is an inflammatory biomarker that has been widely used and suggested as a predictor of mortality in patients with sepsis and septic shock. However, the results are inconsistent. This meta-analysis aimed to evaluate the prognostic value of lactate/albumin ratio as a predictor of mortality in patients with sepsis and septic shock. Methods. The study protocol was registered with PROSPERO (CRD42021286242). A literature search was performed using PubMed, Ovid EMBASE, Ovid MEDLINE, SCOPUS, and Web of Sciences to find all studies evaluating the association between lactate/albumin ratio and mortality in patients with sepsis and septic shock. Meta-analysis was performed to synthesize the overall Standardized Mean Difference (SMD) of the lactate/albumin ratio and the pooled Odds Ratio (OR) for mortality with 95% confidence intervals (95% CI). Heterogeneity was assessed using I 2 . Publication bias was assessed quantitatively with Egger’s test. Analysis was performed using Stata version 16. Results. Seven studies (n=10,264 patients) were included in the meta-analysis. The meta-analysis results showed that non-survivor had a higher lactate/albumin ratio than survivor (random-effects model; SMD 1.47; 95% CI 0,91-2,04; p <0.001). Higher lactate/albumin ratio was associated with an increased mortality in sepsis and septic shock patients (fixed-effects model; OR 1.49 (95% CI 1.37-1.62); p <0.001). Conclusions. High lactate/albumin ratio was associated with mortality in sepsis and septic shock patients. Thus, lactate/ albumin ratio can be used as a predictor biomarker in predicting mortality for sepsis and septic shock patients.
