RESUMO

This study reports a case of Ménétrier's disease (MD) in an adult who presented with epigastric pain and peripheric edema. We focused in particular on the imaging and diagnostic aspects of the presenting case as well as clinical, histologic, and therapeutic aspects. Computed tomography (CT) enteroclysis is a new imaging technique which combines enteroclysis and spiral multislice CT. To the best of our knowledge this is the first report on a MD in an adult patient diagnosed by CT Enteroclysis.

RESUMO

Despite the general progress of the last two decades in oncogenesis mechanism comprehension, in screening and surveillance programs, in technological support to diagnosis and in treatment protocols, the long-term survival of gastrointestinal (GI) cancer patients is not substantially changed. Therefore chemoprevention strategies still appear as a possible alternative to screening and surveillance programs in reducing the incidence and the mortality for GI cancer, at an acceptable cost/effectiveness ratio. The present review is focused on three GI cancers: esophageal adenocarcinoma, gastric cancer and colorectal cancer and their respective precarcinogenic lesions. The authors examine, for each neoplasia, the available chemopreventive agents, their mechanism of action in preventing cancer, the potential targets in the cell growth process, the cost/effectiveness ratio and, whenever present in literature, a comparison with other cancer prevention strategies. The authors conclude that, at present, with the available agents, chemoprevention is not indicated for all patients at low or moderate risk for GI cancer, and should not be considered as a substitute for endoscopic surveillance. In high-risk patients only, both chemoprevention and surveillance could be used. In future more specific agents and combined therapies should be tested in specific group of patients identified by their genomic susceptibility to develop cancer and responsiveness to therapy.

RESUMO

BACKGROUND: Surgical resection is almost inevitable in Crohn's disease. Surgery is usually performed for refractory or complicated disease: no studies appear to have been carried out, so far, to evaluate the potential benefits of performing surgery early in the course of the disease. AIM: To compare the long-term course of Crohn's disease following ileo-caecal resection performed at the time of diagnosis (early surgery) or during the course of the disease (late surgery). Patients and methods Overall 207 patients with ileo-caecal Crohn's disease at their first resection were reviewed: 83 patients underwent surgery at the time of diagnosis (early surgery), while 124 underwent surgery 54.2 months (range 1-438) after diagnosis (late surgery). The mean follow-up after surgery was 147 months (range 12-534). The primary endpoint was clinical recurrence, defined as need for corticosteroids for symptomatic disease in the presence of endoscopic and/or radiologic recurrence. Secondary endpoints were need for immunosuppressants and surgical recurrence. STATISTICAL ANALYSIS: Kaplan-Meier survival method and Cox proportional hazards regression model. RESULTS: Within 10 years after surgery, the cumulative probability of clinical recurrence was significantly lower in the early surgery group (Log Rank test P = 0.01). A trend was observed regarding the need for immunosuppressants (P = 0.05). No difference was observed regarding surgical recurrence. At multivariate analysis, early surgery was the only independent variable associated with a reduced risk of clinical recurrence (Hazard ratio, HR = 0.57; 95% CI 0.35 to 0.92, P = 0.02), but not with need for immunosuppressants and surgical recurrence (HR = 0.51; 95% CI 0.20 to 1.30, P = 0.15; HR = 0.66; 95% CI 0.33 to 1.35, P = 0.25, respectively). CONCLUSION: Early surgery prolongs clinical remission compared to surgery performed during the course of the disease, but the natural history of disease is not modified.

RESUMO

BACKGROUND: A better understanding of predictors of risk for pancreatic ductal adenocarcinoma (PDAC) could inform preventive efforts against this lethal cancer. While aspirin (ASA) and non-steroidal anti-inflammatory drugs (NSAIDS) might protect against several gastrointestinal cancers, their role in the development of PDAC remains unclear. AIM: To conduct a systematic review and meta-analysis on the relation between ASA/NSAIDs exposure and the risk of PDAC. Methods We searched Pubmed, Embase, Scopus, Cochrane database of systematic reviews and reference lists of identified papers and included observational (cohort or case-control) studies and randomized controlled trials examining exposure to ASA and/or NSAIDs and the incidence or mortality of PDAC. We defined three categories (low, intermediate, high), based on exposure duration and dose. RESULTS: Eight studies fulfilled our inclusion criteria (four cohort, three case controls, and one randomized controlled trial studies) enrolling 6301 patients between 1971-2004; all but one study took place in the US. The pooled OR were 0.99 (0.83-1.19), 1.11 (0.84-1.47) and 1.09 (0.67-1.75) in the low, intermediate and high exposure groups respectively, with considerable heterogeneity (I(2) ranging 60-86%). Sensitivity analysis by ASA use only, study design or sex did not reveal additional important information. CONCLUSIONS: This study did not show an association between ASA/NSAIDs and PDAC. The large baseline exposure in controls in North-America may have obscured an association. There is need for additional studies, especially in Europe, to clarify this issue.

RESUMO

BACKGROUND: Mucosa-infiltrated granulocyte neutrophils are an early characteristic of inflammation and the main histological feature of active ulcerative colitis. Mucosal healing has recently been indicated as an important tool in the evaluation of response to treatment. While several studies have stressed the efficacy of granulocyte-monocyte-apheresis in inducing clinical remission in active ulcerative colitis, few data are available on mucosal features. AIM: Aim of this study was to assess the effects of granulocyte-monocyte-apheresis on clinical and mucosal features in patients with ulcerative colitis, dependent upon or refractory to steroids. MATERIAL AND METHODS: From April 2004 to April 2005, 12 patients (5 females, 7 males, mean age 49 years, range 33-71 years), with mild-moderate ulcerative colitis (six left colitis, six pancolitis) dependent/refractory upon steroids were enrolled. Each patient was treated for a 5-week period with five cycles of granulocyte-monocyte-apheresis. Patients were evaluated at baseline and 1 week after the last apheresis by means of Global Physician Assessment, quality of life features, laboratory tests (erythrocyte sedimentation rate, CRP, full blood count, faecal calprotectine), endoscopy and histology. RESULTS: At week 6 of follow-up, complete mucosal healing was observed in 3 out of 12 patients, partial mucosal healing in 8 patients and no change in 1 patient. Clinical response was complete in 8 out of 12 patients. CONCLUSIONS: These data suggest that granulocyte-monocyte-apheresis induces an improvement both in clinical and mucosal lesions in steroid-dependent/refractory ulcerative colitis. Of note, the reduction in granulocyte infiltration and the improvement in mucosal lesions are accompanied by a reduction in faecal calprotectine.

RESUMO

BACKGROUND AND AIMS: Crohn's disease is a heterogeneous entity. The Vienna Classification defines three different clinical patterns: 'non-stricturing, non-penetrating', 'stricturing' and 'penetrating'. Aim of this study was to assess the change in clinical behaviour over time and to evaluate whether an evolution towards penetrating complications can be predicted. METHODS: A total of 139 patients with non-penetrating behaviour at the time of diagnosis were included. The mean follow-up was 4.84 years (range 1-23.2 years). The clinical behaviour, according to the Vienna Criteria, was assessed at the diagnosis and at the end of follow up. Statistical analysis was performed by means of the Kaplan-Meier method and standard logistic regression analysis. RESULTS: The cumulative probability of a change in clinical behaviour was 22, 38 and 63% at 3, 6 and 12 years, respectively, and the cumulative probability of developing penetrating complications was 22, 33 and 55% at 3, 6 and 12 years, respectively. Young age at diagnosis (<40 years) and a stricturing behaviour are independent risk factors of developing major penetrating complications (internal fistula, mass or abscess): OR=6.0, 95% CI 1.1-30.5; OR=4.0, 95% CI 1.5-10.9, respectively, but not perianal disease. CONCLUSIONS: The behavioural classification of Crohn's disease is a dynamic model in which each status should be considered as not fixed but evolutive. Perianal disease should be considered a distinct pattern of penetrating behaviour.

RESUMO

BACKGROUND AND AIMS: In a recent open trial we have shown the efficacy of long term intermittent administration of a poorly absorbable antibiotic (rifaximin) in obtaining symptomatic relief in uncomplicated diverticular disease of the colon. The aim of this double-blind placebo-controlled trial was to test our previous observations. METHODS: One hundred and sixty-eight outpatients with symptomatic uncomplicated diverticular disease were treated with fibre supplementation (glucomannan 2 g/day) plus rifaximin 400 mg b.d. for 7 days every month (84 patients), or with glucomannan 2 g/day plus placebo two tablets b.d. for 7 days every month (84 patients). Clinical evaluation was performed at admission and at three-month intervals for 12 months. RESULTS: After 12 months, 68.9% of the patients treated with rifaximin were symptom-free or mildly symptomatic, compared to 39.5% in the placebo group (P = 0.001). Symptoms such as bloating and abdominal pain or discomfort were primarily affected by antibiotic treatment when compared with placebo (P < 0.001). CONCLUSION: Rifaximin appears to be of some advantage in obtaining symptomatic relief in diverticular disease of the colon when compared with fibre supplementation alone.

RESUMO

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) are strongly associated with gastroduodenal ulcers, and the management of patients with NSAID-associated ulcers represents a common clinical dilemma. AIM: To assess NSAID-associated ulcer healing during treatment with either standard (20 mg) or high dosage (40 mg) omeprazole. METHODS: One hundred and sixty-nine patients chronically ingesting diclofenac, ketoprofen, indomethacin or naproxen for osteoarthritis or rheumatoid arthritis, who had abdominal pain and an endoscopically proven gastroduodenal ulcer, were evaluated in a randomized, double-blind, dose regimen trial with omeprazole 20 mg o.m. (n = 81) or omeprazole 40 mg o.m. (n = 88). Ulcer healing was assessed endoscopically at 4 and 8 weeks in the case of unhealed ulcers. Patients continued their usual daily dose of anti-inflammatory medication throughout the study period. RESULTS: One hundred and fifty-six patients completed the study (77 patients taking 20 mg omeprazole and 79 patients taking 40 mg omeprazole); 12 patients were lost during follow-up and one patient reported an adverse event. Cumulative ulcer intention-to-treat healing rates at 8 weeks were 88% (95% confidence interval (CI) = 79-95%) for the 20 mg omeprazole group and 96.2% (95% CI = 89-99%) for the 40 mg group, and 97.1% (95% CI = 90-100%) for the 20 mg omeprazole group and 98.6% (95% CI = 93-100%) for the 40 mg group by per protocol analysis. There were no statistically significant differences between the two groups. Symptom relief did not differ significantly between the two treatment groups. CONCLUSION: Both standard and high doses of omeprazole are equally safe and effective regimens for the treatment of NSAID-induced gastroduodenal ulcers when anti-inflammatory treatment is not discontinued.

RESUMO

AIM: To perform a meta-analysis to assess the effectiveness and safety of oral budesonide for inducing remission in active Crohn's disease and for preventing relapse in Crohn's disease with medically- or surgically-induced remission. METHODS: All randomized, double-blind controlled trials involving oral budesonide therapy in Crohn's disease were retrieved from a Medline search, reviews articles or their bibliographies. Of 83 articles retrieved, 12 met the inclusion criteria. Data extraction was performed by three independent observers and scoring disagreements were resolved by consensus. RESULTS: Six trials tested budesonide in active disease and six in quiescent disease. Budesonide was less effective than conventional corticosteroids for inducing remission of active Crohn's disease (pooled rate difference, RD -8.5%; 95% CI: -16.4 to -0.7%; P=0.02), but corticosteroid-related adverse events were reduced (RD -22.4%; 95% CI: -32 to -12.8%; P < 0.001). In quiescent Crohn's disease, budesonide was as effective as placebo for preventing relapse in medically induced remission (RD -0.8%; 95% CI: -9.9 to 8.3%; P=0.42) and endoscopic recurrence in surgically induced remission (RD -3.5%; 95% CI: -16.9 to 9.8%; P=0.30). In the long term treatment, budesonide had an occurrence rate of corticosteroid-related adverse effects similar to placebo (RD 5.3%; 95% CI: -3.9 to 14.5%; P=0.30). CONCLUSIONS: Budesonide is significantly less effective than conventional corticosteroids for inducing remission in active Crohn's disease, but the risk of corticosteroid-related adverse effects is significantly reduced. Budesonide is not effective in preventing relapse of Crohn's disease after medically- or surgically-induced remission.

RESUMO

A 24-week, double-blind, randomized study at 13 centres compared the efficacy and safety of 20 mg famotidine nocte and 150 mg ranitidine h.s. for the prevention of duodenal ulcer recurrence. All participants had been successfully treated for an acute duodenal ulcer with 40 mg famotidine nocte. Patients were endoscoped at baseline and at 24 weeks, unless symptoms warranted earlier examination: of the 208 patients enrolled, 86 who received famotidine and 84 who received ranitidine met all protocol criteria and were considered evaluable. Intention to treat and per protocol analyses showed non-significant trends in favour of famotidine (P = 0.44 and 0.16, respectively). During the 24-week observation period, 16.3% of the famotidine group and 25% of the ranitidine group had an ulcer recurrence (95% CI of percentage difference -0.22 + 0.04). At 24 weeks, relief of day and night pain was reported by 81.2% and 91.8% of the famotidine-treated patients, respectively. The corresponding figures in the ranitidine group were 73.5% and 85.5%. No laboratory abnormalities related to the study-drugs were noted and only two drug related (possibly or probably) adverse experiences were reported, both in the famotidine group. The data from this study therefore, supports the conclusion that the efficacy of 20 mg famotidine nocte is comparable to that of ranitidine in preventing duodenal ulcer recurrence, with comparable tolerability for long-term therapy.

RESUMO

METHODS: A multicentre randomized controlled trial was conducted to evaluate the efficacy of oral mesalazine (5-aminosalicylic acid) for the prevention of post-operative recurrence in 110 patients operated on for Crohn's disease by first intestinal resection. Patients were randomly allocated to receive 2.4 g/day of mesalazine, or no treatment at all. The protocol included colonoscopy with ileoscopy at 6 months and yearly thereafter. Recurrence was defined on the basis of endoscopic criteria and classified as mild or severe. RESULTS: The demographic and pre-trial characteristics were very similar in the two groups of patients. The cumulative proportion of recurrence at 6, 12 and 24 months was significantly lower in the mesalazine group than in untreated group (P = 0.002). At 24 months the cumulative proportions of endoscopic recurrence were 0.52 +/- 0.12 (+/- S.E.M.) and 0.85 (+/- 0.07), respectively. At the same time the cumulative proportions of symptomatic recurrence were 0.18 +/- 0.09 and 0.41 +/- 0.09 (P = 0.006). The cumulative proportions of the severe recurrence was also significantly lower in the mesalazine group (0.17 +/- 0.09 vs. 0.38 +/- 0.09; P = 0.021). CONCLUSIONS: The preliminary results of this study show that administration of oral mesalazine soon after surgery is effective in preventing post-operative endoscopic recurrence in Crohn's disease over a 2-year period. It is estimated that this treatment prevents 39% of all recurrences and 55% of the severe recurrences.

RESUMO

BACKGROUND: The aim of this study was to compare omeprazole 10 mg o.m. (daily) with omeprazole 20 mg o.m. on Friday to Sunday inclusive (weekend) in the prevention of duodenal ulcer relapse over a 6-month period. METHODS: After an open healing phase (4 to 8 weeks) with omeprazole 20 mg o.m., 81 patients entered the follow-up phase. Forty-two were randomized in a double-blind double-dummy technique, to omeprazole 10 mg o.m., and 39 to omeprazole 20 mg at weekends. At 3 and 6 months or on symptomatic relapse the patients underwent endoscopy with gastric biopsies (quantitative assessment of argyrophilic and gastrin cells), symptom evaluation, and laboratory screening with fasting serum gastrin. RESULTS: Five patients in the 10 mg group and four in the weekend group were lost to follow-up. The estimated relapse rates over six months in the two groups receiving 10 mg daily or 20 mg at weekends were 19% and 31%, respectively (95% CI of percentage difference: -33% to 8%: intention-to-treat analysis, P = N.S.). During the follow-up phase, symptoms tended to be milder in the omeprazole 10 mg daily group compared to the weekend group. Gastrin levels increased significantly during the healing phase but then stayed almost constant in the omeprazole 10 mg group, and significantly decreased with weekend treatment. The median number of argyrophilic cells showed a slight but statistically significant increase in the omeprazole 10 mg daily group, but did not change in the weekend group. Both the healing and long-term therapies were well tolerated. CONCLUSIONS: Our data do not show a clear difference between the two treatment regimens, but there was a tendency towards a lower recurrence rate with omeprazole 10 mg daily compared with 20 mg weekend therapy.

RESUMO

Helicobacter pylori-associated gastritis is present in virtually all patients with duodenal ulcer (DU). Eradication of H pylori is associated with a highly significant decline in the recurrence rates of DU, indicating that treatments aimed at eradicating H pylori are mandatory in these patients. The novel proton pump inhibitor lansoprazole exhibits a potent antiulcer effect and, in vitro, a direct antibacterial effect against H pylori. Conflicting data have been reported on the question of whether lansoprazole is bactericidal against H pylori in vivo when administered alone. The aim of this double-blind trial was to address this issue further by comparing the effects of two different 4-week regimens (lansoprazole alone or in combination with amoxicillin) on H pylori infection in patients with DU. Patients were assessed before and after the 4-week treatment and 3 months after stopping the study medication. The ulcer healing rates at 4 weeks were similar for the two treatments while there was a trend for higher recurrence rates at 4 months in patients receiving lansoprazole alone. The frequency of high-grade H pylori infection was significantly lower in the lansoprazole and amoxicillin group both at 4 weeks (84% clearing) and 4 months. After 4 weeks of treatment there were no patients with residual H pylori-positive active antral gastritis in the lansoprazole and amoxicillin group compared with 25% in the lansoprazole alone group. Neither treatment significantly affected the IgG antibody response to H pylori either at the circulatory or the mucosal level. In contrast, the mucosal H pylori-specific IgA response was significantly enhanced after 4 weeks and more markedly after treatment with lansoprazole.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

BACKGROUND: Dietary fibres are carbohydrates that resist hydrolysis by human intestinal enzymes but are fermented by colonic microflora. Soluble dietary fibres are fermented by anaerobic bacteria with production of gases, short chain fatty acids and other metabolic products believed to cause symptoms such as bloating, abdominal distension, flatulence. Insoluble fibres are only partially fermented, serving almost exclusively as bulking agents that result in shorter transit time and increased faecal mass. AIMS: To evaluate effect of a supplementation of a single 5 g dose of dietary fibre to a solid meal on gastric emptying, orocaecal transit time, gas production and symptom genesis, in healthy volunteers. Three different dietary fibres were tested, two soluble (guar gum and ispaghula] and one insoluble (microcrystalline cellulose). PATIENTS AND METHODS: After a 24-hour low fibre diet, 10 healthy subjects had a standard meal consisting of white bread and one 70 g egg the yolk of which was mixed with 100 mg of 13C octanoic acid and fried. Breath samples were collected for 13CO2 measurements with a mass spectrophotometer and excretion curve (Tlag, T1/2) evaluation. Further breath samples were collected and analysed with a gas chromatograph for the evaluation of H2 and CH4 production and orocaecal transit time. Each evaluation was repeated adding to standard meal, diluted in 300 ml tap water, respectively: a single 5 g dose of microcrystalline cellulose, guar gum or ispaghula. Subjects were asked to report all symptoms experienced from time of meal ingestion over 24 hours, evaluating the intensity. RESULTS: Dietary fibres did not significantly change gastric emptying (Tlag, T1/2) and orocaecal transit time of standard meal. Subjects experienced more symptoms when meals were supplemented with guar gum (p=0.009 vs standard meal) and ispaghula (p=0.048 vs standard meal). There was a poor, but significant, correlation between gas production and symptoms (r=0. 38, p=0. 01). CONCLUSIONS: Addition of different dietary fibres to a solid meal did not influence gastric emptying and orocaecal transit time. Microcrystalline cellulose caused fewer symptoms than guar gum and ispaghula probably due to the insoluble nature and the dimensions of the particles of this micronised cellulose.

RESUMO

BACKGROUND: 1-2% of all patients under non-steroidal anti-inflammatory drug therapy are exposed to serious upper gastrointestinal complications. The policy of prevention of non-steroidal anti-inflammatory drug-induced gastrointestinal mucosal injury by using misoprostol or suppressing acid secretion is still a matter of debate. AIMS: To discuss the effectiveness of prophylaxis of a gastrointestinal complication during non-steroidal anti-inflammatory drug treatment, according to the number and relevance of risk factors. PATIENTS: A total of 8.843 patients with rheumatoid arthritis, admitted to the widest prospective multicentre mega-trial, on 6-month complication prevention of non-steroidal anti-inflammatory drug-induced ulcers. METHODS: The results are presented in terms of the number of patients to be treated (number needed to treat) in order to prevent one serious upper gastrointestinal complication, and corrected for the number of patients, that receiving the prophylaxis therapy, would lead to one additional withdrawal (number needed to harm). RESULTS: The base-line risk for a complication strongly depended on the number and relevance of risk factors: history of peptic ulcer disease, of gastrointestinal bleeding, of cardiovascular disease, and age. In the general study population, the relative risk reduction of gastrointestinal complications with misoprostol was 40%: thus the number needed to treat to prevent 1 event was 250 in the experimental period (6 months) or 125 when normalized at one-year treatment (1 year number needed to treat]. When considering the prophylaxis gain in intermediate (risk 1-2%) or high risk subjects (patients with a probability of an event over 2%, for the presence of 1 important risk factor or multiple factors), the 1-year number needed to treat rapidly drops from about 100 to about 17. The number needed to harm for one withdrawal was 18. The number needed to treat corrected for withdrawals in order to avoid major complications rises from 125 to 132 in the general population of non-steroidal anti-inflammatory drug users; from 102 to 105 in subjects at intermediate risk, such as patients with history of cardiovascular disease; in the groups at high risk, from 26 to 27 (patients with history of peptic ulcer disease), and from 16 to 17 (patients with history of peptic ulcer disease, cardiovascular disease and aged over 65 years). CONCLUSIONS: Patients at intermediate and high risk for complications from non-steroidal anti-inflammatory drug-induced ulcers should be considered for prophylaxis. In this group of patients, misoprostol prevention of severe complications is effective, and its clinical relevance similar to that of other preventive measures in medical practice.

RESUMO

A multi-centre study with epomediol discoids (200 mg three times daily for 30 days) versus placebo was carried out in 519 patients either with symptoms attributable to hepatopathy and/or alterations in the hepatic function. Epomediol was given to 257 patients chosen at random and the remaining 262 were given placebo. In cases of hepatopathy in which there was no severe damage to the hepatic parenchyma the symptoms of the disease were reduced and the laboratory parameters were improved on treatment with epomediol, whereas the activity of the drug was low in patients with chronic hepatopathy. This confirms that the clinical use of epomediol is most useful in cases of hepatopathy in which the change in hepatic function is still reversible.

RESUMO

The aim of the present study was to evaluate the role of sulglycotide, a molecule with gastroprotective properties, in monotherapy and in association with H2-antagonists in the maintenance treatment of duodenal ulcer. The study was performed using a fully randomized experimental design. Following endoscopic confirmation, 626 patients with healed duodenal ulcer were treated for 6 months with sulglycotide 200 mg tid (293 patients) or sulglycotide + H2-antagonists (333 patients). After 2, 4 and 6 months patients underwent a clinical control whereas an endoscopic control was performed after 6 months. The cumulative percentage of recidivation was 3.6% in the sulglycotide + H2-antagonist treated group, whereas the group treated with sulglycotide alone showed a recidivation rate of 15.4% (p < 0.001). These findings suggest the utility of combined sulglycotide and H2-antagonist treatment in the maintenance therapy for duodenal ulcer.

RESUMO

The irritable bowel syndrome is classified ad "disturbance of intestinal motility without an identifiable anatomic substrate". However, the clear etiopathogenetic implications of a psychosomatic nature complicate the search for an adequate therapeutic strategy. Based on this clinical experience, we set out to check the importance of a spasmolytic with a benzodiazepine and the tolerability of this type of combination. We therefore compared the results in 60 patients with irritable bowel syndrome of 8 weeks' treatment with tablets containing octylonium bromide (OB) 20 mg plus diazepam (DZ) 2 mg or OB 40 mg + 2 mg DZ. The doubling of the spasmolytic without increasing the daily dose of anxiolytic appeared to be useful for reducing the symptoms typical for the irritable bowel syndrome. In addition, the combination was found to be perfectly tolerated.

RESUMO

Aim of this overview was to evaluate the main clinical trials with lansoprazole published from 1997 to 1999 in English-language journals, regarding gastroesophageal reflux disease, peptic ulcer, NSAID-induced ulcer, and ZES. Results of clinical trials for therapy and prevention of lesions/symptoms have been evaluated separately. In direct comparisons, lansoprazole alone (not combined with antibiotics) proves to be equieffective to other PPI and more effective than H2-RA in both therapy and prevention of GERD, peptic ulcer (a part from anti-Hp regimens) and NSAID-induced ulcer. Among Hp-eradicating regimens in patients with peptic ulcer or functional dyspepsia, lansoprazole-based triple therapy is equal in efficacy to other PPI-based or RBC-based triple therapies and, in any case, significantly better than dual therapies. The in vitro anti-Hp activity of lansoprazole, more marked than with other PPI, does not seem to effort clinical advantages. Safety of lansoprazole is largely satisfactory and no different from other PPI and H2-RA.

RESUMO

The suggestion that dietary fibre is of particular importance in our diet is a relatively recent concept. Much of the initial emphasis for increased dietary fibre began with the pioneering work of Burkitt and Trowell in the 1960s who observed that traditional African populations consumed diets high in plant fibre and that these populations experienced very low incidences of non-communicable diseases including cardio-vascular disease, diabetes mellitus and non-infectious bowel diseases, including cancer. Although it is difficult to predict from the chemical structure how dietary fibres will behave physiologically, generally dietary fibre sources can be grouped into two major types: (a) soluble, viscous, fermentable and (b) insoluble, non-viscous, slowly fermentable. As detailed below, these sources of fibres appear to have quite different physiological effects.
