In our study, we aimed to evaluate the relationships of the combination of these inflammatory parameters with albumin, disease severity and prognosis.
Materials and methods: 98 patients diagnosed with sepsis were categorised as survivors (n=68) and nonsurvivors (n=30) according to their intensive care unit (ICU) mortality. Prognostic factors were evaluated with the receiver operating characteristic curve and Cox proportional hazard regression model. Survival was analyzed with the Kaplan-Meier method.
Results: Compared to survivors, nonsurvivors had increased CRP and lactate (13.5 vs 10.0, p=0.044; 2.2 vs 1.7, p=0.006, respectively), while LDH and albumin levels were not significantly different (246.0 vs 245.0, p=0.624; 2.9 vs 3.0, p=0.061, respectively). When combined factors were evaluated, CRP/albumin and lactate/albumin were significantly higher in nonsurvivors (4.9 vs 3.0, p=0.018; 0.8 vs 0.5, p=0.001, respectively), while LDH/albumin was similar in both groups (93.1 vs 78.9, p=0.148). Lactate/albumin had the highest AUC of 0.709 (p=0.001), while CRP had the lowest AUC of 0.628 (p=0.044). In a multivariate analysis of possible predictors of ICU mortality, only lactate could be an independent predictor of poor outcome (HR:1.998; p=0.020), while other variables were not independently associated.
Conclusion: Increased CRP, lactate, CRP/albumin and lactate/albumin levels in septic patients were associated with poor outcomes. Lactate level was an independent predictor of mortality.}, number={3}, publisher={Pamukkale Üniversitesi}
