Abstract
BACKGROUND & AIMS Bowel ultrasonography (BUS) is a noninvasive tool for evaluating bowel activity in Crohn's disease (CD) patients. Aim of our multicenter study was to assess whether BUS helps to monitor intestinal activity improvement/resolution following different biological therapies. METHODS Adult CD patients were prospectively enrolled at 16 sites in Italy. Changes in BUS parameters [i.e. bowel wall thickening (BWT), lesion length, echo pattern, blood flow changes and transmural healing (TH: normalization of all BUS parameters)] were analyzed at baseline and after 3, 6 and 12 months of different biological therapies. RESULTS One hundred eighty-eight out of 201 CD patients were enrolled and analyzed (116 males [62%]; median age 36 years). Fifty-five percent of patients were treated with adalimumab, 16% with infliximab, 13% with vedolizumab and 16% with ustekinumab. TH rates at 12 months were 27.5% with an NNT of 3.6. TH at 12 months after adalimumab was 26.8%, 37% after infliximab, 27.2% after vedolizumab and 20% after ustekinumab. Mean BWT improvement from baseline was statistically significant at 3 and 12 months (P < .0001). Median Harvey-Bradshaw index, C-reactive protein and fecal calprotectin decreased after 12 months from baseline (P < .0001). Logistic regression analysis showed colonic lesion was associated with a higher risk of TH at 3 months and a greater BWT at baseline was associated with a lower risk of TH at 3 months [P = .03 (OR 0.70, 95% CI 0.50-0.97)] and 12 months [P = .01 (OR 0.58, 95% CI 0.38-0.89)]. At 3 months therapy optimization during the study was the only independent factor associated with a higher risk of no ultrasonographic response [P = .02 (OR 3.34, 95% CI 1.18-9.47)] and at 12 months disease duration [P = .02 (OR 3.03, 95% CI 1.15-7.94)]. CONCLUSIONS Data indicate that BUS is useful to monitor biologics-induced bowel activity improvement/resolution in CD.

Abstract
BACKGROUND Mesalazine 1 g suppository/die is used for mild to moderately active ulcerative proctitis (UP). Whether addiction of Multi Matrix System (MMX) mesalazine increases the remission rate of UP and prevents proximal extension of disease is unknown. METHODS This is a retrospective study on 116 outpatients with UP who had been treated with one of the following regimens: (1) MMX mesalazine 1.2 g/die plus mesalazine suppositories for 8 ± 2 weeks and, subsequently, MMX mesalazine 1.2 g/die plus rectal mesalazine 1 g every other day for at least 6 months; (2) mesalazine 1 g suppositories/die alone for 8 ± 2 weeks and, subsequently, rectal mesalazine 1 g every other day for 6 more months. Patients were evaluated clinically at 2 months (±2 weeks) and endoscopically at 6 months (±2 weeks). For categorical variables, Pearson chi-square test was used. RESULTS A total of 46 of 55 patients (84%) on combined therapy and 49 of 61 patients (80%) on rectal mesalazine reached clinical remission (p > 0.05; OR 0.79, 95% CI 0.30-2.07). At 6 months follow-up, proximal extension of disease was observed in 7 of 55 (14%) patients on combined therapy and in 18 of 61 (29%) patients on rectal mesalazine alone (p < 0.05; OR 2.87, 95% CI 1.09-7.53). CONCLUSIONS Oral MMX mesalazine plus rectal mesalazine combined treatment is associated with prevention of proximal extension of the disease compared with rectal mesalazine alone.

Abstract
Oxidative stress leads to chronic liver damage. Silybin has been conjugated with vitamin E and phospholipids to improve its antioxidant activity. Eighty-five patients were divided into 2 groups: those affected by nonalcoholic fatty liver disease (group A) and those with HCV-related chronic hepatitis associated with nonalcoholic fatty liver disease (group B), nonresponders to treatment. The treatment consisted of silybin/vitamin E/phospholipids. After treatment, group A showed a significant reduction in ultrasonographic scores for liver steatosis. Liver enzyme levels, hyperinsulinemia, and indexes of liver fibrosis showed an improvement in treated individuals. A significant correlation among indexes of fibrosis, body mass index, insulinemia, plasma levels of transforming growth factor-beta, tumor necrosis factor-alpha, degree of steatosis, and gamma-glutamyl transpeptidase was observed. Our data suggest that silybin conjugated with vitamin E and phospholipids could be used as a complementary approach to the treatment of patients with chronic liver damage.

Abstract
OBJECTIVES To evaluate whether chronic therapy with probiotics affects plasma levels of cytokines and oxidative/nitrosative stress parameters, as well as liver damage, in patients with various types of chronic liver disease. PATIENTS AND METHODS A total of 22 nonalcoholic fatty liver disease (NAFLD) and 20 alcoholic liver cirrhosis (AC) patients were enrolled in the study and compared with 36 HCV-positive patients with chronic hepatitis without (20, CH) or with (16, CC) liver cirrhosis. All patients were treated with the probiotic VSL#3. Routine liver tests, plasma levels of tumor necrosis factor alpha (TNF-alpha), interleukin (IL)-6 and -10, malondialdehyde (MDA), and 4-hydroxynonenal (4-HNE), S-nitrosothiols (S-NO), were evaluated on days -30, 0, 90, and 120. RESULTS Treatment with VSL#3 exerted different effects in the various groups of patients: in NAFLD and AC groups, it significantly improved plasma levels of MDA and 4-HNE, whereas cytokines (TNF-alpha, IL-6, and IL-10) improved only in AC patients. No such effects were observed in HCV patients. Routine liver damage tests and plasma S-NO levels were improved at the end of treatment in all groups. CONCLUSIONS Results of the study suggest that manipulation of intestinal flora should be taken into consideration as possible adjunctive therapy in some types of chronic liver disease.

Abstract
AIM To define the characteristics of the Italian patient presenting non-alcoholic fatty liver disease. PATIENTS AND METHODS A total of 305 patients with abnormally high plasma aminotransferase and/or gamma-glutamyl-transpeptidase levels for at least 12 months, with no known cause of chronic liver damage, were consecutively enrolled in the study. Clinical, routine biochemical and liver histology investigations were carried out in all patients. Also evaluated were: (a) oral glucose load; (b) insulinaemia and insulin-resistance using the HOMA test model; and (c) plasma endotoxaemia, total antioxidant plasma capability, tumour necrosis factor-alpha, plasma interleukin-6 and -10 levels. Malondialdehyde and 4-hydroxynonenal content were determined on liver samples from 120 patients. RESULTS The majority of patients were young overweight or obese males, with dyslipidaemia (20-60%), diabetes (10.5%), hyperinsulinaemia (40%), hyperferritinaemia (35%). Endotoxaemia was negative in all patients and cytokines were only sporadically altered. Total antioxidant plasma capability was decreased in 38.4% of the patients. Eighty percent of the cases had histological steatosis with a mild degree of inflammation and fibrosis. Seven patients had cirrhosis. Lipid peroxidation markers were increased in 90% of the cases, inversely correlated with fibrosis. Even if at univariate analysis, age, ferritin and tissue 4-hydroxynonenal were independent factors of steatosis (P < 0.01), and insulin, HOMA and ferritin of inflammation and fibrosis (P < 0.01), at multivariate analysis no single factor was found to be an independent predictor of hepatic lesions. CONCLUSIONS The typical Italian patient with non-alcoholic fatty liver disease is a young male, obese, not diabetic, with a variable incidence of dyslipidaemia and hyperinsulinaemia. Only liver biopsy may define the type of liver damage.

Abstract
Two new sesquiterpene cyclopentenones, dysidenones A and B (2, 3), and a new sesquiterpene aminoquinone, dysidine (4), all containing the same rearranged drimane skeleton, have been isolated from a Dysidea sp. sponge, along with bolinaquinone (1). The structures were established from 2D NMR data. Bolinaquinone (1), dysidine (4), and a 1:1 mixture of dysidenones A and B (2, 3) significantly inhibited human synovial phospholipase A2 (PLA2) at 10 microM. Compound 4, which shows an IC50 value of 2.0 microM, exerts a higher potency and selectivity toward this enzyme than the reference inhibitor manoalide. In addition, all of these compounds modulated at 10 microM other human leukocyte functions such as the degranulation process measured as elastase release and the superoxide production measured by chemiluminescence.

Abstract
In a previous study, we reported a new bioactive sesquiterpenoid, named dysidotronic acid, to be a potent, selective human synovial phospholipase A(2) inhibitor. Dysidotronic acid is a novel, non-complex manoalide analogue lacking the pyranofuranone ring. We now investigate the effect of this compound on cytokine, nitric oxide and prostanoid generation on the mouse macrophage cell line RAW 264.7, where it showed a dose-dependent inhibition with inhibitory concentration 50% values in the micromolar range. This effect was also confirmed in the mouse air pouch injected with zymosan. Dysidotronic acid inhibited the production of tumor necrosis factor alpha and interleukin-1 beta as well as the production of nitric oxide, prostaglandin E(2) and leukotriene B(4). Decreased nitric oxide generation was the consequence of inhibition of the expression of nitric oxide synthase, whereas PGE(2) and LTB(4) reduction was due to inhibition of arachidonic acid bioavailability through a direct inhibitory effect of dysodotronic acid on secretory phospholipase A(2).

Abstract
Callipeltin A, a cyclic depsipeptide from the New Caledonian Lithistida sponge Callipelta sp., is a macrocyclic lactone containing four amino acids in the L configuration, Ala, Leu, Thr (2 residues); one (Arg) in the D configuration; two N-methyl amino acids, N-MeAla and N-MeGln; a methoxy tyrosine, a 3, 4-dimethyl-l-glutamine; and a 4-amino-7-guanidino-2,3 dihydroxypentanoic acid (AGDHE), formally derived from L-Arg. In cardiac sarcolemmal vesicles Callipeltin A induces a powerful (IC(50) = 0.85 microM) and selective inhibition of the Na(+)/Ca(2+) exchanger. In electrically driven guinea-pig atria, at concentrations ranging between 0.7 and 2.5 microM, Callipeltin A induces a positive inotropic effect, which at the highest concentrations is accompanied by a rise in resting tension. It is suggested that the positive inotropic effect is linked to the inhibition of the Na(+)/Ca(2+) exchanger and that Callipeltin A may be an useful tool to study the role of the cardiac Na(+)/Ca(2+) exchanger in physiological and pathological conditions.

Abstract
A total of 22 sulfated sterols isolated from marine sponges, ophiuroids (brittle stars), and asteroids (sea stars) were comparatively evaluated for their antiviral activity against HIV-1 and HIV-2. In general, sterols with sulfate groups at position 2, 3, or 6 were the most active, with EC50 values of 3-13 microM against HIV-1 (RF) and 2-8 microM against HIV-2 (CBL20). Those compounds which were sulfated on the sterol D ring were completely inactive against both HIV-1 and HIV-2. Overall, sulfated sterols active against HIV-1 were also active against HIV-2.
