Inflammatory bowel disease patients have an increased risk of early atherosclerosis as shown by greater values of cIMT, carotid artery stiffness, Hyc, hsCRP, and insulin resistance.

To assess the effects of anti-TNF-alpha antibody (infliximab) in experimental steatohepatitis induced by methionine- and choline-deficient (MCD) diet. The study included thirty rats. One group received normal rat food, and two groups received MCD diet. The treatment group received a single dose intra-peritoneal infliximab (4 mg/kg), at week 8. MCD diet increased levels of AST, ALT, TNF-alpha, TGF-beta(1), tissue and plasma MDA (p < 0.05 for each). Moreover, it led to steatosis, ballooning degeneration, inflammation, fibrosis and increased actin expression, histopathologically (p < 0.05 for each). In this experimental steatohepatitis anti-TNF-alpha antibody decreased the levels of AST, ALT, TGF-beta(1) and plasma and tissue MDA (p < 0.05 for each). Moreover, inflammation, necrosis, actin expression and fibrosis decreased in anti-TNF-alpha group compared to placebo group (p < 0.05 for each). This study indicates that anti-TNF-alpha antibody is effective on necrosis, inflammation and fibrosis in the experimental model of non-alcoholic steatohepatitis, induced by MCD diet.

Summary Background Results are conflicting with respect to the renal effects of anti‐viral agents used for hepatitis B virus infection. Aim To compare short and long‐term renal effects in real‐life settings and to determine risk factors for renal impairment during treatment. Methods 2221 treatment‐naïve patients were enrolled. Among these, 895 (302 lamivudine, 27 telbivudine, 282 entecavir, 273 tenofovir and 11 adefovir initiated patients) had ‘repeated measures’ of creatinine (baseline, 1st, 6th, 12th and 24th month of treatment). Telbivudine and adefovir groups were excluded from further analysis because of the low number of patients. We calculated the glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease (MDRD) formula at each time point. Hypophosphataemia was also recorded. Risk factors for renal impairment were analysed. Results Tenofovir caused a decline in GFR at each time point when compared to baseline levels. However, lamivudine and entecavir did not change GFR. GFR‐shifting from ≥90 to 60–89 mL/min/1.73 m2 was comparable among groups. The proportion of patients whose baseline creatinine increased more than 25% was comparable among all anti‐virals. GFR showed a decline in patients who switched from entecavir to tenofovir. One patient with compensated cirrhosis needed to change from tenofovir because of renal safety. Seven and three patients developed transient hypophosphataemia in the tenofovir and lamivudine groups, respectively. Conclusions Although tenofovir caused a decline in GFR, differences between the anti‐viral agents do not appear to be so impressive. In patients with and without renal risk factors at baseline, there is no impact of anti‐virals, including tenofovir.

Prevalence of HGM was 3.6%. Dysphagia was found related with the size of HGM. This may be associated with larger HGMs' causing more acid secretion.

To assess the effect of infliximab, an anti-tumor necrosis factor (TNF)-alpha agent, on the carbon tetrachloride (CCl(4))-induced hepatic fibrosis in rats. Rats were randomized into three groups (n=9). The control group received only intraperitoneal (i.p.) olive oil. Hepatic fibrosis was induced by repeated i.p. injections of 1.5 ml/kg CCl(4) (1:3 mixture with olive oil) for 5 weeks in the remaining two groups which were also injected subcutaneous saline or 2 mg/kg infliximab. Infliximab reduced the levels of aspartate aminotransferase and alanine aminotransferase (p<0.05 for both). The scores of hepatic necrosis, inflammation and fibrosis, and expression of alpha-smooth muscle actin were lower in the infliximab-treated group than the CCI(4)-treated group (p<0.01, p<0.001, p<0.01, p<0.001, respectively). However, there was no significant difference in terms of liver tissue and plasma malondialdehyde, and serum TNF-alpha levels, while infliximab relatively reduced the level of transforming growth factor-beta(1) (373.0+/-153.1 vs. 280.8+/-127.1 pg/ml). Treatment with infliximab attenuated the necro-inflammation and fibrogenesis in the CCI(4)-induced hepatic fibrosis, and thus it might be effective as a therapeutic anti-fibrotic agent.
