SUMMARYBackground: Patients with inflammatory bowel disease have an increased risk of thrombotic complications; moreover, mesenteric microvascular thrombosis has been hypothesized as a contributing factor in the pathogenesis of inflammatory bowel disease. Aim: To assess the extent of subclinical atherosclerosis in inflammatory bowel disease by measuring the intima-media thickness of the common carotid artery. Methods: Fifty-two patients were enrolled in the study. Patients aged >45 years, with a history of cardiovascular disease and known risk factors for atherosclerosis were excluded from the study. Twenty healthy subjects were studied as controls. Carotid ultrasonography was performed in all patients and controls. intima-media thickness was measured proximal to the carotid bifurcation

SUMMARY BackgroundPsoriasis is an emerging paradoxical side effect in patients with inflammatory bowel disease (IBD) when treated with anti-TNF alpha. Patients with severe skin lesions unresponsive to topical therapy need to withdraw from treatment.

The clinical introduction of tumour necrosis factor (TNF) inhibitors has deeply changed the treatment of inflammatory bowel diseases (IBD). It has demonstrated impressive efficacy as compared to alternative treatments, allowing for the chance to achieve near-remission and long-term improvement in function and quality of life and to alter the natural history of Crohn's disease (CD) and ulcerative colitis (UC). As a consequence of longer follow-up periods the number of side effects which may be attributed to treatment with biologics is growing significantly. Cutaneous reactions are among the most common adverse reactions. These complications include injection site reactions, cutaneous infections, immune-mediated complications such as psoriasis and lupus-like syndrome and rarely skin cancers. We review the recent literature and draw attention to dermatological side effects of anti-TNF therapy of inflammatory bowel disease.

Infliximab was more effective than azathioprine in reducing histological, but not endoscopic and clinical recurrence after curative ileocolonic resection in "high risk" CD patients.

Background and Aims Our first objective was to evaluate the immune response to the adjuvanted 2009 A/H1N1 pandemic (pH1N1) vaccine in inflammatory bowel disease (IBD) patients treated with anti-TNF-α alone or combined with immunosuppressants (IS). Second and third aims were the safety of pH1N1 vaccine and the effects on IBD clinical activity. Methods 36 patients with Crohn's disease (CD) and 26 with ulcerative colitis (UC) and thirty-one healthy control subjects (HC) were enrolled. 47 patients were on anti TNF-α maintenance monotherapy and 15 on anti TNF-α combined with IS. Sera were collected at baseline (T0) and 4 weeks after the vaccination (T1) for antibody determination by hemagglutination inhibition (HAI Disease activity was monitored at T0 and T1. Results Seroprotective titers (≥ 1: 40) in patients were comparable to HC. Seroconvertion rate (≥ 4 fold increase in HAI titer) was lower than HC in IBD patients (p=0,009), either on anti TNF-α monotherapy (p=0,034) or combined with IS (p=0,011). Geometric mean titer (GMT) of antibodies at T1 was significantly lower in patients on combined therapy versus those on monotherapy (p=0,0017) and versus HC (p=0,011). The factor increase of GMT at T1 versus T0 was significantly lower in IBD patients versus HC (p=0,042), and in those on combined immunosuppression, both versus monotherapy (p=0,0048) and HC (p=0,0015). None of the patients experienced a disease flare. Conclusion Our study has shown a suboptimal response to pH1N1 vaccine in IBD patients on therapy with anti TNF-α and IS compared to those on anti-TNF-α monotherapy and HC.

HBV and HCV infection rates were similar to infection rates among the general population. Less than one quarter of the patients had been vaccinated against HBV. Anti-TNF-α agents appear to be safe for patients with HBV infection; more data are needed for patients with HCV infection.
