Background: Hepatitis viruses are non-cytopathic viruses that lead to the infection and pathogenesis of liver diseases as a result of immunologically mediated event. Objective: To investigate the expression of human inflammatory cytokines in chronic hepatitis B patients according to the severity of the infection. Methods: We recruited a total of 120 patients, 40 of whom from cirrhotic, 40 non-cirrhotic, and 40 acute flare chronic hepatitis B and 40 healthy controls. For all groups total cellular RNA was extracted from whole blood samples, genomic DNA was eliminated, and cDNA was synthesized using the RT2 first strand kit, as instructed by the manufacturer. The real-time profiler PCR array was performed on an a master cycler ep realplex and the data were analyzed using an online data analysis software. Results: Non-cirrhotic chronic hepatitis B patients were found to significantly upregulate interleukin 10 receptors that regulate the balance between T helpers 1 and 2. On the other hand, patients with cirrhosis were found to have significant upregulated interleukin 3 gene expression. Conclusion: Our finding suggests that upregulation of anti-inflammatory and downregulation of pro-inflammatory cytokines may play a roles in the progression of non-cirrhotic chronic hepatitis B patients to cirrhotic and acute flare. However, a multi-center study with a larger sample size is needed to confirm our findings.

Background: The clinical significance of antiphospholipid antibodies in patients with chronic hepatitis C virus (HCV) and some other viral infections is controversial. Objective: To study the prevalence of anticardiolipin antibody (ACLA) and antibeta2glycoproteinI antibody (antibeta2GPI antibody) in HCV and hepatitis B virus (HBV) infected patients and its association with liver clinical parameters. Methods: Serum levels of ACLA, antibeta2GPI antibody as well as platelet count, ALT (alanine transaminase), PT (prothrombine time), disease duration and liver histologic findings of 38 patients with HBV and 15 patients with HCV infections were compared with those of 58 healthy controls. Results: Serum titres of ACLA in HCV and HBV patients (13.4 ±7.1 GPL units/ml), and in each of the HCV (15.18±9.91 GPL units/ml) and HBV (12.7 ± 5.7 GPL units/ml) patients were significantly higher than that of the control group (3.4±2.3GPL units/ml). However, there was no significant difference in serum levels of antibeta2GPI antibody from patients with HCV and HBV (3.3 ± 1.3 GPL units/ml) or HCV alone (2.79 ± 1.01 GPL units/ml) or HBV alone (3.4±1.3GPL units/ml) and that of the control group (3.3±1.1GPL units/ml). Conclusion: The findings suggest that the presence of ACLA has no pathologic significance in patients with HBV and HCV infections.

Objective: To compare immunogenicity of a recombinant hepatitis B (HB) vaccine in two groups of neonates born in two cities of Iran with different geographic and ethnic backgrounds. Materials and Methods: Ten micrograms of a recombinant HB vaccine was administered under field condition to Iranian healthy neonates at 0, 1.5 and 9 months intervals. The subjects consisted of two groups of 290 and 231 neonates selected from two cities located at north-west (Urmia) and south-east (Kerman) of Iran, respectively. The level of anti-HBs antibody was quantitated in serum 2-4 weeks after administration of the last vaccine dose, by sandwich ELISA. Results: A higher seroprotection rate (anti-HBs> 10 IU/L) (98.3% vs. 96.1%) and significantly increased serum anti- HBs antibody titer (11869 vs. 6104 IU/L) (P<0.001) were induced in vaccinated neonates from Urmia city, compared to those born in Kerman. Conclusion: These findings suggest contribution of ethnic and/or environmental factors in the antibody response to recombinant HB vaccine in human.
