Abstract
OBJECTIVE Folate has heterogeneous functions and is involved in several activities in both animal and human body. It is an important constituent of our organism, and its bioavailability is mainly dependent from the correct function of our gastrointestinal tract. Our aim is to describe what happens to folate homeostasis in gastrointestinal health and disease, analyzing the alterations of folate metabolism in some specific conditions of intestinal and liver impairment. DISCUSSION Folate absorption and metabolization involve the small intestine and the liver; in conditions of gastrointestinal tract disease (i.e. celiac disease, liver disease) folate function may be compromised with important consequences on the whole organism. Moreover, folate deficiency may produce gastrointestinal alterations too. For this reason, the gastrointestinal tract could be the responsible but also the victim of folate deficiency. CONCLUSIONS The presence of folate deficiency should always be assessed in patients with a gastrointestinal disease. Further studies are needed to assess the role of folates in gastrointestinal tract diseases and in other gynecologic, neurologic, psychiatric, cardiovascular, ophthalmic and neoplastic diseases. Folates supplementation could be considered, in the future, as an effective complimentary therapy in several pathologic conditions.

Abstract
Some patients affected by nickel-contact allergy present digestive symptoms in addition to systemic cutaneous manifestations, falling under the condition known as systemic nickel allergy syndrome (SNAS). A nickel-related pro-inflammatory status has been documented at intestinal mucosal level. The aim of the present study is to evaluate the prevalence of lactose intolerance in patients affected by SNAS compared to a healthy population. Consecutive patients affected by SNAS referring to our departments were enrolled. The control population consisted of healthy subjects without gastrointestinal symptoms. All subjects enrolled underwent lactose breath test under standard conditions. One hundred and seventy-eight SNAS patients and 60 healthy controls were enrolled. Positivity of lactose breath test occurred in 74.7% of the SNAS group compared to 6.6% of the control group. Lactose intolerance is highly prevalent in our series of patients affected by SNAS. Based on our preliminary results, we can hypothesize that in SNAS patients, the nickel-induced pro-inflammatory status could temporarily impair the brush border enzymatic functions, resulting in hypolactasia. Further trials evaluating the effect of a nickel-low diet regimen on lactase activity, histological features and immunological pattern are needed.

Abstract
BACKGROUND Double-balloon enteroscopy is a newly developed endoscopic method allowing non-surgical full-length exploration of the small bowel, biopsies sample and endoscopic treatment of previously inaccessible lesions. AIM To prospectively assess the diagnostic and therapeutical impact of double-balloon enteroscopy in patients with suspected or documented small bowel disease. PATIENTS AND METHODS One hundred consecutive patients referring to our centre for suspected small bowel disease underwent double-balloon enteroscopy. Starting insertion route (anal or oral) of double-balloon enteroscopy was chosen according to the estimated location of the suspected lesions basing on the clinical presentation and on the findings, when available, of previous endoscopic or radiological investigations. Major indications for the procedures were acute recurrent or chronic mid-gastrointestinal bleeding (n=71), suspected gastrointestinal tumours (n=10), suspected Crohn's disease (n=6), chronic abdominal pain and/or chronic diarrhoea (n=8), refractory celiac disease (n=5). RESULTS One hundred and eighteen double-balloon enteroscopy procedures were carried out. Oral and anal route double-balloon enteroscopies were performed in 54 and 28 patients, respectively, while 18 patients underwent a combination of both approaches. Overall diagnostic yield of double-balloon enteroscopy resulted 69%. Most common pathological findings included angiodysplasias (n=39), ulcerations and erosions of various aetiologies (n=21), tumours (n=7) and ileal stenosis in patients with Crohn's disease suspicion (n=2). In the 65% of the patients examined, double-balloon enteroscopy findings influenced the subsequent clinical management (endoscopic, medical or surgical treatment). No major complications related to the procedure occurred. CONCLUSIONS Our prospective analysis shows that double-balloon enteroscopy is a useful, safe and well-tolerated new method with a high diagnostic and therapeutic impact for the management of suspected or documented small bowel diseases.

Abstract
BACKGROUND Rifaximin is a broad spectrum non-absorbable antibiotic used for treatment of small intestinal bacterial overgrowth. Doses of 1200 mg/day showed a decontamination rate of 60% with low side-effects incidence. AIMS To assess efficacy, safety and tolerability of rifaximin 1600 mg with respect to 1200 mg/day for small intestinal bacterial overgrowth treatment. METHODS Eighty consecutive small intestinal bacterial overgrowth patients were enrolled. Diagnosis of small intestinal bacterial overgrowth based the clinical history and positivity to H(2)/CH(4) glucose breath test. Patients were randomized in two 7-day treatment groups: rifaximin 1600 mg (group 1); rifaximin 1200 mg (group 2). Glucose breath test was reassessed 1 month after. Compliance and side-effect incidence were also evaluated. RESULTS One drop-out was observed in group 1 and two in group 2. Glucose breath test normalization rate was significantly higher in group 1 with respect to group 2 both in intention-to-treat (80% vs. 58%; P < 0.05) and per protocol analysis (82% vs. 61%; P < 0.05). No significant differences in patient compliance and incidence of side effects were found between groups. CONCLUSIONS Rifaximin 1600 mg/day showed a significantly higher efficacy for small intestinal bacterial overgrowth treatment with respect to 1200 mg with similar compliance and side-effect profile.

Abstract
BACKGROUND Aminosalicylates are the mainstay of therapy to prevent relapse of quiescent ulcerative colitis. The rationale for using probiotics is based on the evidence implicating intestinal bacteria in the pathogenesis of this disorder. AIM To evaluate the efficacy of Lactobacillus GG alone or in combination with mesalazine vs. mesalazine as maintenance treatment in ulcerative colitis. PATIENTS AND METHODS 187 ulcerative colitis patients with quiescent disease were randomized to receive Lactobacillus GG 18 x 10(9) viable bacteria/day (65 patients), mesalazine 2400 mg/day (60 patients) or Lactobacillus GG + mesalazine (62 patients). Disease activity index, endoscopic and histological scores were determined at 0, 6 and 12 months and in case of relapse. The primary end point was to evaluate sustained remission. RESULTS Overall analysis showed no difference in relapse rate at 6 (P = 0.44) and 12 months (P = 0.77) among the three treatment groups. However, the treatment with Lactobacillus GG seems to be more effective than standard treatment with mesalazine in prolonging the relapse-free time (P < 0.05). CONCLUSIONS Lactobacillus GG seems to be effective and safe for maintaining remission in patients with ulcerative colitis, and it could represent a good therapeutic option for preventing relapse in this group of patients.

Abstract
BACKGROUND Standard anti-Helicobacter pylori therapy may not achieve a satisfactory eradication rate. Fluoroquinolones, such as moxifloxacin, are safe and promising agents for H. pylori eradication. AIM To compare the efficacy of two 1-week moxifloxacin-based H. pylori eradication regimens with two standard treatments. METHODS Three hundred and twenty H. pylori-positive subjects were randomized into four groups to receive: moxifloxacin, amoxicillin, esomeprazole (Group MAE); moxifloxacin, tinidazole and esomeprazole (Group MTE); standard triple therapies with clarithromycin, amoxicillin and esomeprazole (Group CAE) or tinidazole (Group CTE) for 7 days. H. pylori status was re-assessed 6 weeks after the end of therapy by 13C urea breath test. RESULTS Three hundred and twenty patients completed the efficacy analysis per protocol; H. pylori eradication rate in group MTE was 90% (72 of 80) and 92% (72 of 78), in group MAE was 88% (70 of 80) and 89%, (70 of 79) in Group CAE was 73% (58 of 80) and 78% (58 of 74), and in Group CTE was 75% (60 of 80) and 79% (60 of 76), respectively, in intention-to-treat and in per protocol analyses. Eradication rates of moxifloxacin-based triple therapies were significantly higher than that observed using standard triple schemes. The incidence of side effects was significantly lower in moxifloxacin groups than in control groups. CONCLUSIONS Seven-day moxifloxacin-based triple therapies provide optimal eradication rates with a good compliance when compared with the standard triple therapy schemes.

Abstract
BACKGROUND Helicobacter pylori eradication fails in about 10% of patients, particularly because of the occurrence of resistance to antibiotics and side-effects. During anti-H. pylori therapy, probiotics have been successfully used to reduce the incidence of side-effects. AIM To evaluate the effect of Bacillus clausii, a probiotic, on incidence (primary variable) and severity of antibiotic-associated side-effects during anti-H. pylori therapy. METHODS One hundred and twenty H. pylori-positive patients were randomly screened to receive: (i) a standard 7 days triple therapy with rabeprazole 20 mg b.d., clarithromycin 500 mg b.d. and amoxicillin 1 g b.d. and B. clausii t.d.s. (each preparation containing 2 x 10(9) spores) for 14 days starting from the first day of treatment. (ii) The same 7 days triple therapy and placebo t.d.s. for 14 days starting from the first day of treatment. Side-effects were assessed using a validated questionnaire and were recorded for 4 weeks from the start of therapy. RESULTS The incidences of nausea, diarrhoea and epigastric pain in patients treated with B. clausii were significantly lower than in placebo group, in both PP and ITT analysis. Equally, intensity of nausea and diarrhoea in patients treated with B. clausii was significantly lower than in placebo group. There were no differences in adherence to treatment and H. pylori eradication rates between groups. Conclusion : In symptom-free, H. pylori-positive subjects B. clausii bacteriotherapy reduces the incidence of the most common side-effects related to anti-H. pylori antibiotic therapy compared with placebo.

Abstract
BACKGROUND Levofloxacin has been shown to be effective in Helicobacter pylori eradication. Two 10-day levofloxacin-based triple therapies were compared with standard 7- and 14-day quadruple regimens in second-line treatment. METHODS Two hundred and eighty consecutive patients who failed to respond to standard triple therapy (clarithromycin, amoxicillin, rabeprazole) were randomly assigned to four groups: (1) levofloxacin 500 mg o.d., amoxicillin 1 g b.d., rabeprazole 20 mg b.d. for 10 days (LAR, n = 70); (2) levofloxacin 500 mg o.d., tinidazole 500 mg b.d., rabeprazole 20 mg b.d. for 10 days (LTR, n = 70); (3) tetracycline 500 mg q.d.s., metronidazole 500 mg t.d.s., bismuth salt 120 mg q.d.s., rabeprazole 20 mg b.d. for 7 days (7TMBR, n = 70); and (4) for 14 days (14TMBR, n = 70). Helicobacter pylori status and side-effects were assessed 6 weeks after treatment. RESULTS The eradication rate was 94% in the LAR group and 90% in the LTR group in both intention-to-treat and per protocol analyses. Helicobacter pylori eradication was achieved in 63 and 69% of the 7TMBR group and in 69 and 80% of the 14TMBR group in intention-to-treat and per protocol analysis, respectively. Side-effects were significantly lower in the LAR and LTR groups than in the 14TMBR group. CONCLUSION Ten-day levofloxacin-based therapies are better than standard quadruple regimens as second-line option for H. pylori eradication.

Abstract
Carbon-labelled breath tests were proposed as tools for the evaluation of human liver function 30 years ago, but have never become part of clinical routine. One reason for this is the complex role of the liver in metabolic regulation, making it difficult to provide essential information for the management of patients with liver disease with a single test and to satisfy the hepatology community. As a result, a battery of breath tests have been developed. Depending on the test compound administered, different metabolic pathways (microsomal, cytosolic, mitochondrial) can be examined. Most available data come from microsomal function tests, whilst information about cytosolic and mitochondrial liver function is more limited. However, breath tests have shown promise in some studies, in particular to predict the outcome of patients with chronic liver disease or to monitor hepatic function after treatment. Whilst we await new substrates that can be used to measure liver function in a more valid manner, and large prospective studies to assess the usefulness of available test compounds, the aim of this review is to describe how far we have come in this controversial and unresolved issue.
