Prognostic Value of Routine Biochemistry Profile of Liver Transplant Patients Admitted to the Emergency Department with a Suspected Infection
Introduction: Since patients who have undergone liver transplantation should take immunosuppressants for life, the prevalence of systemic infections after this procedure is very high. These infections are associated with increased mortality and morbidity. Objective: This study aimed to investigate the prognostic value of routine biochemistry profile and its relationship with mortality in liver transplant patients admitted to the emergency department (ED) with a suspected infection. Methods: Patients who had undergone liver transplantation were included in the study. The patients were divided into three groups of culture-negative, culture-positive and control. White blood cell (WBC) count, hemoglobin (Hb), platelet (Plt), international normalized ratio (INR), creatinine (Cr), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) values as well as vital sign findings were comparatively evaluated in terms of their ability to show the presence of any infection and their correlation with mortality. Results: Totally, 142 patients were enrolled and were divided into the following three groups: 41 cases in culture-negative group, 30 cases in culture-positive group, and 71 cases in control group. There was not any significant difference between study groups in terms of age and sex ratio (p>0.05). The Hb and Plt values of the culture-positive patients were significantly lower, and their INR was significantly higher compared to those in control group (p<0.05). Fever, Hb, Plt, INR, AST and ALT values were factors that had a significant correlation with mortality in patients with an infection whethere culture-positive or culture-negative ones (p<0.05). Conclusions: In patients admitted to the ED with a history of liver transplantation, we recommend the evaluation of vital signs and Hb, PLt, and INR values to determine whether there is an infection or not. We can also state that mortality risk is higher in cases with low Hb and Plt levels and high INR, ALT, and AST values.
