Summary
Background
Psoriasis 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.
Aim
To estimate the incidence of paradoxical psoriasis in a large cohort of IBD patients treated with anti‐TNF alpha and to analyse its clinical correlates.
Methods
A retrospective cohort study on all IBD patients who started anti‐TNF alpha at our IBD Centre from January 2008 to December 2013 was performed. Proportional hazards regression models were used to estimate the association between each predictor and time to the development of psoriasis. Time‐dependent predictors were updated at each available time point.
Results
Four hundred and two patients were included. Participants contributed a total of 839 person‐years of follow‐up, during which 42 incident cases of psoriasis were recorded, with an incidence rate of five per 100 person‐years. Cox‐regression survival analysis revealed smoking as independent predictor of psoriasis (HR: 2.37, 95% CI: 1.36–4.48; P = 0.008). Conversely, concomitant immunosuppressive therapy was inversely related to psoriasis (HR: 0.33, 95% CI: 0.12–0.92; P = 0.03).
Conclusions
Paradoxical psoriasis is a relevant side effect of anti‐TNF alpha therapy, with an incidence rate of five per 100 person‐years. Smoking is confirmed as the main risk factor for developing lesions. The combination therapy with anti‐TNF alpha plus immunosuppressants is associated with a reduced risk of paradoxical psoriasis.

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.
36 patients with Crohn's disease (CD) and 26 with ulcerative colitis (UC) and thirty-one healthy control (HC) subjects 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 4weeks after the vaccination (T1) for antibody determination by hemagglutination inhibition (HAI). Disease activity was monitored at T0 and T1.
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.
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.

Summary
Background : 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 over both right and left common carotid arteries. The clinical characteristics and the laboratory parameters relevant to disease activity were recorded for all inflammatory bowel disease patients. In particular, plasma homocysteine, a well‐known risk factor for thrombosis, was assessed.
Results : Common carotid artery intima–media thickness was significantly higher in inflammatory bowel disease patients (0.63 ± 0.15 mm) compared with controls (0.53 ± 0.08 mm). Multiple regression analysis revealed a significant association of carotid intima–media thickness with homocysteine levels and age.
Conclusions : Inflammatory bowel disease patients have an increased risk of early atherosclerosis than healthy controls as showed by greater values of carotid intima–media thickness. Homocysteine levels and age resulted independently associated with the increased arterial wall thickness.

Irritable bowel syndrome (IBS) is a chronic gastrointestinal (GI) disorder that affects 15-20% of the Western population.
There are currently few therapeutic options available for the treatment of ...IBS. The aim of this study is to evaluate the efficacy and the safety of a medical device containing a combination of Simethicone and Bacillus coagulans in the treatment of IBS.
This is a monocentric double-blind, placebo-controlled parallel group clinical trial. Adult subjects suffering from IBS as defined by Rome III criteria were enrolled. Bloating, discomfort, abdominal pain were assessed as primary end point. Subjects received the active treatment or placebo 3 time a day after each meal for 4 weeks of study period. Subjects were submitted to visit at Day 0 (T1), at Days 14 (T2) and 29 (T3).
Fifty-two patients were included into the study. Intragroup analysis showed a significant reduction of the bloating, discomfort and pain in Colinox® group (CG) compared to placebo group (PG). Between group analysis confirmed, at T1-T3, significant differences between CG and PG in bloating and discomfort.
Simethicone is an inert antifoaming able to reduce bloating, abdominal discomfort. Literature offers increasing evidence linking alterations in the gastrointestinal microbiota and IBS and it is well known that probiotics are important to restore the native gut microbiota. The Colinox medical device is specifically targeted against most intrusive symptom of IBS (bloating) and it is also able to counteract the most accredited ethiopathogenetic factor in IBS (alterations of intestinal microbiota).
This is the first randomized double-blind placebo-controlled clinical trial demonstrating the efficacy and safety of a combination of simethicone and Bacillus coagulans in treatment of IBS.
During infliximab treatment of perianal Crohn’s disease (CD), the healing of the skin opening precedes fistula tract healing and this contributes to abscess formation and fistula recurrence. The aims ...of this study were to evaluate the efficacy of combined treatment with infliximab and setons for complex perianal fistulas in CD and to define the optimal time for seton removal by anal endosonography (AE). Nine consecutive patients with CD were studied. Perianal sepsis was eradicated when necessary and setons were placed before infliximab therapy. Setons were removed after AE evidence of fistulous tracts healing. Patients received a mean of 10±2.3 infliximab infusions. At week 6 all patients showed a reduction in mean CD activity index (
p
<0.005) and perianal disease activity index (
p
<0.0001). Complete fistula response was achieved in eight of nine patients. In six patients after a mean of 9.2 infusions, infliximab treatment was discontinued. Clinical and AE response persisted at 19.4±8.8 months (range 3–28 months) in five of these patients. One patient had fistula recurrence 20 weeks after infliximab discontinuation and responded rapidly to retreatment. At the time of this report, two patients were still on infliximab and in remission after a mean follow-up of 25±5 months. Combined therapy with infliximab and setons with AE monitoring of the response showed high efficacy in the management of patients with CD with complex perianal fistulas.
