    Background and Aims. Liver fatty acid-binding protein (L-FABP) is a small molecule. The aim of this study was to examine L-FABP levels and to detect its diagnostic value in chronic hepatitis C (CHC). Methods. We studied 22 patients with CHC and 20 healthy control subjects. Patients with persistently elevated serum aminotransferases and positive HCV RNA were included in the study. Patients with CHC underwent percutaneous liver biopsy. Serum level of L-FABP was determined by ELISA method. Results. Patients with CHC had significantly increased levels of L-FABP compared to controls. A strong correlation between serum L-FABP concentrations and aspartate aminotransferases, alanine aminotransferases, HCV RNA levels and hepatic inflammation was found. When a cut-off value was 29,000 pg/mL for L-FABP, sensitivity and specificity were 75 and 100%, respectively. Positive and negative predictive values for L-FABP were 100 and 78%, respectively. Conclusions. Serum L-FABP is used as a new diagnostic marker to detect liver injury. (C) 2013 IMSS. Published by Elsevier Inc.

    Midkine level may be used as a noninvasive biomarker in Crohn's disease

    Background/aim: Crohn's disease (CD) is a kind of inflammatory bowel disease. Midkine (MDK) is an endogenous inflammatory marker. We aimed to investigate the relationship between MDK levels and inflammation and hence determine whether MDK can be used as a noninvasive biomarker in active CD. Materials and methods: Sixty-five consecutive patients over the age of 18 with CD and 36 healthy controls were included in this study. CD patients' venous blood samples were taken before treatment. Serum MDK levels were determined in human plasma samples by enzyme-linked immunosorbent assay (ELISA) method. Results: The mean age of the study patients was 44.8 +/- 12.5 years, 35 patients were female, and 30 were male. Of these 65 patients, 37 had active CD and 28 were in the remission phase. MDK levels were significantly higher in active and remission CD than in healthy controls (P = 0.01, P = 0.038, respectively). Conclusion: We report that there is an association between MDK levels and CD activation, and therefore with enhanced inflammation. MDK levels were significantly correlated with inflammatory indices. In line with our findings, we suggest the theory that MDK inhibitors may be useful in treating Crohn's disease.
