L-FABP as a potential biomolecular marker of liver graft injury
Ana Kalamutova, Danaja Plevel, Mihajlo Djokić, Aleš Jerin, Blaž Trotovšek, Miha Petrič, 2025, izvirni znanstveni članek

Povzetek: Background: In recent years, indications for liver transplantation have expanded, while the age of transplant recipients has significantly increased due to improvements in perioperative management. As clinical manifestations of posttransplant complications vary and are often nonspecific, the identification of appropriate biomarkers is important for the assessment of graft quality and early recognition of potential complications following liver transplantation. Liver-type FABP (L-FABP) is a small cytoplasmic protein found abundantly in hepatocytes and is involved in the intracellular transport of long-chain fatty acids. Elevated serum levels have been detected in acute and chronic liver failure, kidney failure, and some malignancies. Materials and Methods: We conducted a prospective, single-center study from July 2023 to January 2025, including 29 adult patients who underwent deceased-donor transplantation. Three patients were excluded due to inadequate sample withdrawals. Serum L-FABP was measured preoperatively and on postoperative days 1, 3, 5, 7, and 14. Clinical, surgical, and biochemical data were collected and analyzed using non-parametric statistical tests. Results: L-FABP levels were significantly higher on POD 7 in recipients of grafts from donors ≥ 65 years (p = 0.035), with no corresponding changes in standard liver function markers. While no significant differences in L-FABP levels were found between patients with and without infectious biliary or vascular complications (all p > 0.05), we proved a strong negative correlation between intraoperative blood transfusion volume and L-FABP levels on POD 5 (ρ = −0.677, p < 0.001) and POD 7 (ρ = −0.455, p = 0.025). Conclusions: Our findings suggest that L-FABP holds promise as a biomarker for the early detection of subclinical hepatic graft cellular injury, which is not detected by means of conventional biomarkers for liver function.

Radiological assessment of skeletal muscle index and myosteatosis and their impact postoperative outcomes after liver transplantation
Miha Petrič, Taja Jordan, Karteek Popuri, Sabina Ličen, Blaž Trotovšek, Aleš Tomažič, 2023, izvirni znanstveni članek

Povzetek: Background. Liver transplantation offers curative treatment to patients with acute and chronic end-stage liver disease. The impact of nutritional status on postoperative outcomes after liver transplantation remains poorly under-stood. The present study investigated the predictive value of radiologically assessed skeletal muscle index (SMI) and myosteatosis (MI) on postoperative outcomes.Patients and methods. Data of 138 adult patients who underwent their first orthotopic liver transplantation were retrospectively analysed. SMI and MI in computer tomography (CT) scan at the third lumbar vertebra level were cal-culated. Results were analyzed for the length of hospitalisation and postoperative outcomes.Results. In 63% of male and 28.9% of female recipients, low SMI was found. High MI was found in 45(32.6%) patients. Male patients with high SMI had longer intensive care unit (ICU) stay (P < 0.025). Low SMI had no influence on ICU stay in female patients (P = 0.544), length of hospitalisation (male, P > 0.05; female, P = 0.843), postoperative complication rates (males, P = 0.883; females, P = 0.113), infection rate (males, P = 0.293, females, P = 0.285) and graft rejection (males, P = 0.875; females, P = 0.135). The presence of MI did not influence ICU stay (P = 0.161), hospitalization (P = 0.771), postoperative complication rates (P = 0.467), infection rate (P = 0.173) or graft rejection rate (P = 0.173).Conclusions. In our study, changes in body composition of liver transplant recipients observed with SMI and MI had no impact on postoperative course after liver transplantation. CT body composition analysis of recipients and uni-formly accepted cut-off points are crucial to producing reliable data in the future.
