Evaluation of Serum Kallistatin in Patients with Hepatocellular Carcinoma

Abstract Background Liver cirrhosis is the most frequent long-term consequence of all chronic liver diseases. Cirrhosis is often asymptomatic and unsuspected until complications. The annual incidence rates of liver cirrhosis and hepatocellular carcinoma is related with chronic hepatitis B or C all over the world. The majority of patients with liver cirrhosis or hepatocellular carcinoma die from complications, which happened relatively early in the course of the disease. Thus, the early diagnosis of liver diseases is the only solution for this great problem. Aim of the Work In the current study we aimed to evaluate serum kallistatin in Egyptian patients with hepatitis C virus related liver cirrhosis and hepatocellular carcinoma. Patients and Methods This case control study enrolled 90 Egyptian subjects aged ≥ 18 years old at Ain shams university hospitals, participants were classified into 3 groups as follow: Group 1: 30 patients with hepatocellular carcinoma (patients have been diagnosed with triphasic CT). Group 2: 30 patients with hepatitis C virus related liver cirrhosis (patients diagnosed according to clinical, laboratory and radiological findings. Group 3: 30 healthy subjects serving as a control group. Results This study found that patients with liver cirrhosis and HCC have lower levels of serum Kallistatin compared to a control group. In the HCC group, patients with more severe liver disease (Child class C) had lower Kallistatin levels than those with less severe disease (Child class A and B). Kallistatin was negatively correlated with certain markers of liver disease and inflammation in both groups, and positively correlated with hemoglobin and albumin. The study also tested the diagnostic accuracy of Kallistatin for detecting liver cirrhosis and HCC, and found that it had 66.5% accuracy for cirrhosis and 98% accuracy for HCC at specific cutoff points. Conclusion Serum Kallistatin has a potential rule as a new biomarker for the diagnosis and evaluation of liver cirrhosis and HCC. The present study was limited by the small sample size. Also, all participants were from the Egyptian population with liver disease induced by HCV- infection with no information if our findings would be valid for other population with different etiologies. Thus, further investigation should be carried out in order to validate these findings
