High concentration

of sTNFR-II has been observed for prolonged periods in the circulation of patients with various inflammatory diseases (including HCV infection), making sTNFR-II an ideal serum biomarker for characterizing type 1 immune response [29–32]. Moreover, IL-8 contributes to human cancer progression through potential mitogenic, and angiogenic functions. IL-8 expressions plays a more critical role in the metastatic potential of human HCC (such as vascular invasion) than in angiogenesis or tumor proliferation [33]. Our aim was to evaluate the serum levels of sFas, TNFR-II, IL-2R and IL-8 as possible candidate biomarkers for an early detection of HCC. Results The clinical #selleck chemicals llc randurls[1|1|,|CHEM1|]# characteristics of the studied groups are shown in Table 1. All recruited patients were positive for HCV antibodies, PCR for HCV RNA and all had genotype-4. Mean age of patients with HCC was significantly higher than that of the other groups (p < 0.001). Liver function tests were significantly elevated, whereas log-HCV titer was significantly lower in HCC patients (p < 0.001) when compared to patients with chronic hepatitis C with persistent normal alanine aminotransferase

levels (PNALT) and chronic selleckchem liver disease (CLD) patients. Figure 1 shows the distribution of log-HCV titer in the different study groups, which included 68 men and 29 women. Mann-Whitney test was used for comparing log-HCV, sFas, sTNFR-II, sIL-2R and IL-8 values with gender. Comparing the means of men versus women, the former had only higher

and significant (p = 0.04) log-HCV titer (11.16 ± 4.1) and (9.7 ± 1.5), respectively; however, all other markers did not statistically differ. Table 1 Patients characteristics and log-HCV titer among the Histidine ammonia-lyase different study groups Variables Control (9) PNALT (17) CLD (32) HCC (30) p -value M/W 7/2 12/5 24/8 25/5 < 0.001 Age (years): Mean ± SD 50.9 ± 4.6b 35.1 ± 11.5c 43.4 ± 8.7b 60.7 ± 8.3a < 0.001 Log HCV-titer <615* 10.9 ± 3.2a 9.9 ± 4.1a 5.2 ± 4.7b < 0.001 Groups with similar letters are not different statistically. A p -value < 0.05 was considered significant. M/W: Men/Women; PNALT: chronic hepatitis C with persistent normal alanine aminotrasferase; CLD: chronic liver disease; HCC: hepatocellular carcinoma. *All cases were under detection limit (<615 IU/ml) and so they were not included in the statistical analysis (Kruskal-Wallis ANOVA). Figure 1 Scatter diagram of the distribution of log-HCV titer results among the different study groups. PNALT: Chronic hepatitis C with persistent normal alanine aminotrasferase; CLD: Chronic liver disease; HCC: hepatocellular carcinoma. Table 2 depicts the comparison of the serum levels of sFas, sTNFR-II, sIL-2Rα and IL-8. HCC patients had higher sFas, sTNFR-II and sIL-2R than patients with PNALT, CLD and normal controls with a significant difference for sFas between HCC patients and control (p < 0.001).
