Early Expression of Hepatocyte Growth Factor, Interleukin-6, and Transforming Growth Factor-β1 and -β2 in Symptomatic Infection in Patients Who Have Undergone Liver Transplantation

Abstract: Introduction: Early septic complications may be a deciding factor for successful recovery among patients who have undergone orthotopic liver transplantation. Therefore, monitoring liver function parameters plays an important role in postoperative treatment to achieve an early diagnosis of postsurgical complications. We ought to measure standard liver function parameters and the expression levels for selected cytokines among patients exhibiting symptoms of infection after orthotopic liver transplantation. Materials and methods: The study was performed on 30 patients who were divided into two groups: SI-0 consisted of patients free of infection, and SI-1, those who had symptoms of infection. We determined standard liver function parameters and expression of hepatocyte growth factor (HGF), interleukin (IL)-6, transforming growth factor (TGF)-β1, and TGF-β2. Results: There were no significant differences in standard liver function parameters between the two groups of patients. There were no significant differences in the levels of expression for the cytokines in question between the two groups of patients. Conclusions: Although standard liver function parameters provide diagnostically valuable information on the patient''s condition, they cannot be used to determine the extent of systemic infection among patients showing signs of infection after liver transplantation. Determining gene expression levels in circulating lymphocytes is a sensitive method to monitor patients'' condition after liver transplantation. The expression levels of HGF, IL-6, TGF-β1, and TGF-β2 in circulating lymphocytes were not sufficiently specific to diagnose transitory postsurgical complications such as symptomatic infection.
