ABSTRACT
PURPOSE: There are many risk factors for postoperative acute kidney injury in liver transplantation. The aim of this study is to investigate the risk factors for postoperative acute kidney injury in living donor liver transplantation recipients. METHODS: 220 living donor liver transplantation recipients were retrospectively evaluated in the study. According to the Kidney Disease Improving Global Outcomes Guidelines, acute kidney injury in postoperative day 7 was investigated for all patients. The patient's demographic data, preoperative and intraoperative parameters, and outcomes were recorded. RESULTS: Acute kidney injury was found in 27 (12.3%) recipients. In recipients with acute kidney injury, female population, model for end-stage liver disease score, norepinephrine requirement, duration of mean arterial pressure less than 60 mmHg, the usage of gelatin and erythrocyte suspension and blood loss were significantly higher than recipients with nonacute kidney injury (for all p<0.05). In multivariate analyses, the likelihood of acute kidney injury on postoperative day 7 were increased 2.8-fold (1.1-7.0), 2.7-fold (1.02-7.3), 3.4-fold (1.2-9.9) and 5.1-fold (1.7-15.0) by postoperative day 7, serum tacrolimus level ≥10.2 ng dL-1, intraoperative blood loss ≥14.5 mL kg-1, the usage of gelatin >5 mL kg-1 and duration of MAP less than 60 mmHg ≥5.5 minutes respectively (for all p<0.05). CONCLUSIONS: In living donor liver transplantation recipients, serum tacrolimus levels, intraoperative blood loss, hypotension period and the usage of gelatin may be risk factors for acute kidney injury in the early postoperative period.
ABSTRACT
OBJECTIVES: Sepsis is one of the most common reasons of increased mortality and morbidity in the intensive care unit. The changes in CRP levels and hemogram parameters and their combinations may help to distinguish sepsis from non-sepsis SIRS. The aim of this study is to investigate the CRP and hemogram parameters as an indicator of sepsis. METHODS: A total of 2777 patients admitted to the ICU of two centers between 2006-2013 were evaluated retrospectively. The patients were diagnosed as SIRS (-), non-sepsis SIRS and sepsis. The patients who were under 18 years old, re-admitted, diagnosed with hematological disease, on corticosteroid and immunosuppressive therapy, SIRS (-), culture negative, undocumented laboratory values and outcomes were excluded. 1257 patients were divided into 2 groups as non-sepsis SIRS and sepsis. The patients' demographic data, CRP levels, hemogram parameters, length of ICU stay and mortality were recorded. RESULTS: 1257 patients were categorized as non-sepsis SIRS (816, 64.9%) and sepsis (441, 35.1%). In the multivariate analysis, the likelihood of sepsis was increased 3.2 (2.2-4.6), 1.7 (1.2-2.4), 1.6 (1.2-2.1), 2.3 (1.4-3.8), 1.5 (1.1-2.1) times by the APACHE II≥13, SOFA score≥4, CRP≥4.0, LymC<0.45 and PLTC<150 respectively (p<0.001 p = 0.007 p = 0.004 p<0.001 p = 0.027). The likelihood of sepsis was increased 18.1 (8.4-38.7) times by the combination of CRP≥4.0, lymC<0.45 and PLTC<150 (P<0.001). CONCLUSIONS: While WBCC, NeuC, Neu%, NLCR and EoC are far from being the indicators to distinguish sepsis from non-sepsis SIRS, the combinations of CRP, LymC and PLTC can be used to determine the likelihood of sepsis.
