Abstract
Background Diverticulosis is increasing worldwide as a public health problem. The Combined Overview on Diverticular Assessment (CODA) score, merging Diverticular Inflammation and Complication Assessment (DICA) and few clinical parameters, may reliably predict the occurrence of acute diverticulitis and surgery due to complications. Thus, the aim of the study is to confirm the value of DICA classification and to develop and validate the CODA endoscopic-clinical score. Methods A number of 2198 patients, at the first diagnosis of diverticulosis/diverticular disease were enrolled in a multicentre, prospective, international cohort study. Participants were scored according to DICA classifications. A 3-year follow-up was performed. Survival methods for censored observation were used to develop and validate the CODA score for predicting diverticulitis and surgery. Results The 3-year cumulative probability of diverticulitis and surgery was ≤4%, and ≤0.7% in CODA A; <10%and <2.5% in CODA B; >10%and >2.5% in CODA C, respectively. The 3-year cumulative probability of diverticulitis and surgery was of 3.3% (95% CI 2.5% to 4.5%) in DICA 1, 11.6% (95% CI 9.2% to 14.5%) in DICA 2 and 22.0% (95% CI 17.2% to 28.0%) in DICA 3 (p < 0.001), and 0.15% (95% CI 0.04% to 0.59%) in DICA 1, 3.0% (95% CI 1.9% to 4.7%) in DICA 2 and 11.0% (95% CI 7.5% to 16.0%) in DICA 3 (p < 0.001), respectively. The CODA score showed optimal discrimination capacity in predicting the risk of surgery in the development (cstatistic: 0.829; 95%CI 0.811 to 0.846) and validation cohort (c-statistic: 0.943; 95% CI 0.905 to 0.981). Conclusions DICA endoscopic classification was confirmed to have a significant predictive value in terms of acute diverticulitis occurence/recurrence and risk of surgery. CODA score could provide a new risk stratification tool useful for everyday clinical practice and also with a significant public health impact in terms of treatment effectiveness and decision making. Key messages • DICA endoscopic classification of diverticular disease is a clear predictor of the outcome of diverticulosis/diverticular disease. • The CODA score, combining DICA and few clinical parameters, may reliably predict the occurence of acute diverticulitis and surgery due to complications.

Abstract
Abstract
Background
Diverticulosis of the colon is the most frequent anatomical alteration detected during colonoscopy. The endoscopic classification “DICA”(Diverticular Inflammation and Complication Assessment) has been recently developed in order to have an objective endoscopic description of the colon harbouring diverticula. Aim of this multicentre, international, prospective study was to assess the predictive value of this classification in term of acute diverticulitis and surgery occurrence on a 2-year observational follow-up period.
Methods
2215 prospective patients at the first diagnosis of diverticular disease were enrolled after exclusion of radiological signs of acute diverticulitis; inflammatory bowel diseases; ischemic colitis; prior colonic resection; patients with severe liver failure (Child-Pugh C) or severe kidney failure; pregnant women; patients who are currently using or who have received any laxative agents or mesalazine or probiotics or antibiotics < 2 weeks prior to the enrollment; inability to comply with study protocol; patients with or history of cancer, of any origin, within 5 years before enrollment; history of alcohol, drug, or chemical abuse.
Results
1377(62.15%) patients were classified as DICA 1, 599(27,04%) as DICA 2 and 239(10.80%) as DICA 3. The risk of acute diverticulitis occurrence/recurrence, as well as the risk of surgery, were significantly linked to the severity of DICA score at entry. Overall, acute diverticulitis occurred in 123 (5,5%) patients: it occurred in 32 (2,3%) DICA 1, 53 (8,9%) DICA 2 and 32 (16.4%) DICA 3 patients respectively (p < 0,0001). Overall, surgery occurred in 35 (1,6%) patients: it occurred in 2 (0.1%) DICA1, 15 (2,5%) DICA 2 and 18 (7,6%) DICA 3 patients respectively (p < 0,0001).
Conclusions
The 2-year results of this prospective study seems to confirm that DICA endoscopic classification has a significant prognostic role on the risk of acute diverticulitis occurrence/recurrence and surgery in these patients.
Key messages
DICA is the first endoscopic classification of diverticular disease. The risk of occurrence/recurrence of acute diverticulitis and the risk of surgery are strictly linked to the severity of DICA score.

Abstract
Abstract
Colonic Diverticulosis is one of the most common anatomic alterations found in the clinical practice. This condition has 60% incidence in the population over 60 years old. About 20% of patients with this condition will develop Diverticular Disease, and 5% of them will evolve into Diverticulitis. The aim of the study is to analyse the validation of the classification considering the distribution of the severity DICA score between the patients with diagnosis of colonic Diverticulosis.
We analysed and classified with DICA 5635 colonoscopies in the period between January 2012 and April 2018 and we obtained the Hospital Discharge Form from all the patients that had been admitted to the hospital in the same time period. The results showed that 69.9% of the patients were assigned to the score DICA1, 21% to DICA2 and 9.1% to DICA3. Ageing increased both the diagnosis of Diverticular Disease and the severity score. The severity was higher in female patients (DICA1=44.6%,DICA2=50.8%,DICA3=57.8%). The occurrence of complications overall was 5.4% and specifically: not complicated Diverticular Disease (DICA1=1%, DICA2=1.8%, DICA3=3.5%); not complicated Diverticulitis (DICA1=2.1%, DICA2=4.7%, DICA3=6.4%); Bleeding in Diverticulitis (DICA1=0.4%, DICA2=1.2%, DICA3=4.5%); Diverticular Perforation (DICA1=0.0%, DICA2=0.1%, DICA3=0.4%). The complications that needed a surgical procedure were for DICA1 about 0.2%, for DICA2 0.8% and for DICA3 2.5%. As well the average of the occupant days in the hospital and the cost, respectively, was for DICA1:8.5 days and 2300 €; for DICA2:9.5 days and 3080 €; for DICA 3:13 days and 4090 €.
The majority of the patients with Diverticular Disease belonged to the severity score DICA1 and the patients classified with DICA3 were mainly female and older than 69 years old. The study confirmed the prognostic value of the endoscopic classification DICA since the occurrence of complication resulted in a statistically significant relation with the score DICA3.
Key messages
DICA classification was able to discriminate, based on endoscopic records, the patients that could develop complications for Diverticular Disease. DICA classification is a valid parameter to predict the outcome of the disease, with great impact on public health improving the effectiveness of treatment.

Abstract
BACKGROUND Hypothyroidism, characterised by low/normal free thyroxine (FT4) and free triiodothyronine (FT3) with elevated thyroid-stimulating hormone (TSH), is a well-known complication of nephrotic syndrome (NS). This is a common feature of primary and secondary glomerular diseases and comprises loss of protein in the urine and increased urinary excretion of thyroid hormones and thyroxine- binding globulin. With a normal thyroid reserve, this scenario is associated with the development of subclinical hypothyroidism, with a slight increase in TSH and normal free fractions. However, with a low thyroid reserve the transition toward overt hypothyroidism is almost inevitable, affecting morbidity and mortality. As T4 replacement is a cheap and well-established treatment to achieve a stable hormone status in different types of thyroid deficiency, it is essential to recognise and appropriately treat this condition. CONCLUSION In this article we summarise the evidence on this nephro-endocrine disorder in humans and focus on diagnostic and therapeutic strategies.

Abstract
The HID-AB histologic staining technique, which distinguishes sulphomucin from sialomucin types of intestinal metaplasia, was employed in endoscopic gastric mucosal biopsies to evaluate their frequency of association with epithelial dysplasia. Sulphomucin-type intestinal metaplasia was found in 33% of the cases under observation; moderate or severe dysplasia was only associated with this type of intestinal metaplasia. Its precancerous significance can be ascertained only by means of prospective studies.

Abstract
To define the frequency of gastric epithelial dysplasia (precancerous lesion), 1463 biopsies from 842 endoscopically studied patients were reassessed. Mild dysplasia was found in 19.9 % of the cases, moderate in 4.1 %, severe in 0.95 %. Since the clinical and biological significance of the lesion is still an open question, indications for follow-up are discussed in the light of personal views, together with a critical evaluation of the recently proposed classifications.

Abstract
Cardiorenal syndrome (CRS) describes the concurrent failure of cardiac and renal function, each influencing the other. Malnutrition and cachexia frequently develop in patients with heart failure or kidney failure. However, no information is currently available on the prevalence of malnutrition in CRS patients. We studied CRS patients admitted to an internal medicine ward during a 5-month period and evaluated their clinical characteristics and nutritional status. Malnutrition risk was assessed by using the validated screening tool NRS-2002 whilst body composition was assessed by bioimpedance analysis and muscle function was measured by handgrip (HG) strength. Cardiac mass was also recorded. Length of stay, hospital readmission and 6-month mortality were registered. During the study period, 22 CRS patients were studied. Twenty patients were diagnosed with either CRS type 1 or CRS type 5. In CRS patients, fat-free mass showed a trend toward representing a protective factor for 6-month mortality (OR=0.904; p=0.06). Also, fat-free mass correlated with HG strength and cardiac ejection fraction. Malnutrition risk was diagnosed in 45% of the patients, whereas 8 patients met the definition of cachexia. Even without statistical significance, CRS patients with malnutrition had lower BMI (Body Mass Index) (p=0.038) and fat-free mass (p= n.s.). However, CRS malnutrition was associated to higher 6-month mortality (p= 0.05), and appears to negatively influence the outcome in CRS (OR= 9; p= 0.06). Our results show that malnutrition is prevalent in CRS patients and influences the clinical outcome. The assessment of nutritional status, and particularly body composition, should be implemented in daily practice of patients with CRS.

Abstract
The risk of venous thromboembolism (VTE) is increased across the spectrum of chronic kidney disease (CKD), from mild to more advanced CKD, and typically characterizes nephrotic syndrome (NS). VTE risk in patients with kidney disease may be due to underlying hemostatic abnormalities, including activation of pro-thrombotic factors, inhibition of endogenous anticoagulation systems, enhanced platelet activation and aggregation, and decreased fibrinolytic activity. The mechanisms involved differ depending on the cause of the kidney impairment (i.e. presence of NS or CKD stage). Sex and gender differences, as well as, environmental factors or comorbidities may play a modulating role; however, specific sex and gender data on this topic are still rare. The aim of the present review is to discuss the VTE risk associated with impairment of kidney function, the potential mechanism accounting for it and the impact of sex differences in this clinical setting.

Abstract
OBJECTIVE Cardio-Renal Syndrome (CRS) is a condition, which is more frequently observed in clinical practice. The aim of this study is to explore nutritional status and intrarenal arterial stiffness in patients affected by CRS. PATIENTS AND METHODS 14 consecutive CRS patients, screened for anthropometry, biochemistry, nutritional and metabolic status underwent renal Doppler ultrasound and whole-body bioimpedance spectroscopy (BIS). RESULTS We found a positive correlation between phase angle (PA) and CKD-EPI and MDRD (p=0.011 and p=0.007), and between body mass index and renal resistive index (RRI) (p=0.002). Finally, we found a negative correlation between fat-free mass and RRI (p=0.024). CONCLUSIONS Body composition assessment may improve the care of patients with chronic kidney disease (CKD). Also, BIS may help identify changes in hydration status in CKD patients resulting as a significant predictor of mortality.

Abstract
BACKGROUND Autoimmune gastritis leads to oxyntic gastric atrophy, a condition at increased risk for gastric cancer. Autoimmune gastritis in conjunction with autoimmune thyroid disease has been reported previously. AIM In a case-control study in patients with autoimmune thyroid disease to evaluate the usefulness of serum pepsinogens for the identification of oxyntic gastric atrophy, and to determine the relationship of Helicobacter pylori with oxyntic gastric atrophy. METHODS Patients with autoimmune thyroid disease (cases) and goitre (controls) were prospectively enrolled in the study. Pepsinogen (PG) I levels ≤25 μg/mL and PG I/II ratio ≤3 were indicative for oxyntic gastric atrophy. Antibodies against H. pylori, CagA and parietal cells were also determined. Esophagogastroduodenoscopy with biopsies was offered to patients with serological oxyntic gastric atrophy. RESULTS In total, 34 autoimmune thyroid disease patients and 30 controls were enrolled. Serological oxyntic gastric atrophy was present only in autoimmune thyroid disease patients (8/34, 23.5%, OR 8.3, 95% CI = 1.9-36.2). In all eight patients oxyntic gastric atrophy was confirmed by histology. OLGA stage I, II, III and IV was described in 0%, 33%, 50% and 17% of the cases, respectively. About, 89% and 11% of oxyntic gastric atrophy patients were seropositive for antibodies against parietal cells or H. pylori infection, respectively. Gastric atrophy involved the angulus/antrum in 50% of patients with autoimmune gastritis. CONCLUSIONS The seroprevalence of oxyntic gastric atrophy is high in patients with autoimmune thyroid disease, and testing of serum pepsinogens should be included in the clinical assessment of these patients. H. pylori infection is unlikely to be a principal factor in the pathogenesis of oxyntic gastric atrophy in patients with autoimmune thyroid disease. In autoimmune gastritis, gastric atrophy can spread from the oxyntic towards the antral mucosa.

Abstract
A variety of infections has been recognized as an important cause of morbidity and mortality in patients with nephrotic syndrome, and membranous nephropathy is a common cause of this in the elderly. The reasons for infection risk are due to oedema complications, urinary loss of factor B and D of the alternative complement pathway, cellular immunity, granulocyte chemotaxis, hypogammaglobulinemia with serum IgG levels below 600 mg/dL, and secondary effects of immunosuppressive therapy. Many different prophylactic interventions have been used for reducing the risks of infection in these patients but recommendations for routine use are still lacking. We report two membranous nephropathy cases in the elderly in which Intravenous immunoglobulin were useful in long-term infectious prophylaxis, showing safety in renal function. During immunosuppressant therapy in membranous nephropathy, intravenous immunoglobulin without sucrose are a safe therapeutic option as prophylaxis in those patients with nephrotic syndrome and IgG levels below 600 mg/dL. The long-term goal of infection prevention in these patients is to reduce mortality, prolong survival and improve quality of life.

Abstract
BACKGROUND Mesalazine seems to be effective in preventing recurrence of acute uncomplicated diverticulitis (AUD), but the optimal mesalazine scheme to achieve these results is still debated. AIM To assess the effectiveness of two different mesalazine-based treatments in preventing recurrence of AUD and the occurrence of other complications of diverticular disease (DD) during a long-term follow-up. PATIENTS AND METHODS We reviewed 311 patients suffer from recent episode of AUD and undergoing to mesalazine treatment: 207 (group A, 105 males, median age 63 years, range 47-74 years) were treated with mesalazine 1.6 g for 10 days each month, whilst 104 (group B, 55 males, median age 65 years, range 50-72 years) were treated with mesalazine 1.6 g every day. Patients were followed-up every 6 months (median 7.5 months, range 5-13 months). RESULTS Patients were followed-up for a mean time of 3 years (range 12-72 months). Overall, occurrence of complication recurred more frequently in group A than in group B (p = 0.030, log-rank test). Acute diverticulitis recurred in 17 (8.2%) patients in group A and in 3 (2.9%) in group B; diverticular bleeding occurred in 4 (1.9%) patients in group A and in 1 (0.96%) patient in group B; surgery was required in 3 (1.4%) patients in group A and in no (0%) patient in group B. CONCLUSIONS This is the first study showing that long-term mesalazine treatment is significantly better that intermittent mesalazine treatment in preventing occurrence of DD complications after an attack of acute diverticulitis.

Abstract
Atrophic gastritis (resulting mainly from long-standing Helicobacter pylori infection) is a major risk factor for (intestinal-type) gastric cancer development and the extent/topography of the atrophic changes significantly correlates with the degree of cancer risk. The current format for histology reporting in cases of gastritis fails to establish an immediate link between gastritis phenotype and risk of malignancy. The histology report consequently does not give clinical practitioners and gastroenterologists an explicit message of use in orienting an individual patient's clinical management. Building on current knowledge of the biology of gastritis and incorporating experience gained worldwide by applying the Sydney System for more than 15 years, an international group of pathologists (Operative Link for Gastritis Assessment) has proposed a system for reporting gastritis in terms of stage (the OLGA staging system). Gastritis staging arranges the histological phenotypes of gastritis along a scale of progressively increasing gastric cancer risk, from the lowest (stage 0) to the highest (stage IV). This tutorial aims to provide unequivocal information on how to consistently apply the OLGA staging system in routine diagnostic histology practice.

Abstract
BACKGROUND In inflammatory bowel diseases, changes in autonomic enteric regulation may also affect neural cardiovascular control. However, while cardiac autonomic modulation has been shown to be impaired in active ulcerative colitis, the occurrence of cardiovascular autonomic alterations, also in the quiescent phase of inflammatory bowel diseases, is still a matter of debate. The aim of our study was thus to explore the features of cardiovascular autonomic regulation in ulcerative colitis and Crohn's disease during their remission phase. MATERIALS AND METHODS Autonomic cardiovascular control was evaluated by time- and frequency-domain indexes of spontaneous heart rate and blood pressure variability and by assessing the baroreflex heart rate control (sequence technique) in 26 patients with ulcerative colitis, in 26 patients with Crohn's disease and in 23 healthy controls. RESULTS The groups were matched for age, gender and body mass index. They had similar blood pressure mean levels and variability. By contrast, mean heart rate, its overall variability (standard deviation), and baroreflex sensitivity were lower in ulcerative colitis patients than in controls. Moreover, all indexes related to cardiac vagal control were significantly lower in ulcerative colitis patients with respect not only to controls but also to Crohn's disease patients. CONCLUSIONS Cardiac vagal control is impaired in quiescent ulcerative colitis only, and not in Crohn's disease, while in both bowel diseases vascular control appears preserved. Since cardiovagal modulation seems related to anti-inflammatory mechanisms, the reduced parasympathetic cardiac regulation in apparently quiescent ulcerative colitis suggests that such systemic derangement is accompanied by local subclinical inflammations, even in the absence of clinically active inflammatory processes.

Abstract
Chitinous material was isolated from the mycelium of seven species of Basidiomycetes to evaluate the possibility of using fungal biomass as a source of chitin and chitosan. Such material was characterised for its purity, degree of acetylation and crystallinity. Chitin yields ranged between 8.5 and 19.6% dry weight and the chitosan yield was approximately 1%. The characteristics of the fungal chitins were similar to those of commercial chitin. Chitosans, with a low degree of acetylation, comparable with that of commercial chitosan, were obtained by the chemical deacetylation of fungal chitins.

Abstract
BACKGROUND Cure rates for eradication of Helicobacter pylori appear to be decreasing, thus more effective therapies must be identified. AIM To evaluate the efficacy of bovine lactoferrin in the treatment of H. pylori infection. METHODS In a multicentered prospective study, 402 (mean age 52.4, range 19-84 years) H. pylori-positive patients were assigned to one of three regimens: group A - esomeprazole 20 mg b.d., clarithromycin 500 mg b.d. and tinidazole 500 mg b.d. for 7 days; group B - lactoferrin 200 mg b.d. for 7 days followed by the same schedule of group A; group C - esomeprazole 20 mg b.d., clarithromycin 500 mg b.d. and tinidazole 500 mg b.d. plus lactoferrin 200 mg b.d. for 7 days. RESULTS Of the 402 patients, 389 completed the study. Six patients were discontinued due to side effects, one patient in group B died and six patients were lost to follow up. The eradication rate (intention-to-treat analysis) was 77% in group A (105/136), 73% in group B (97/132) and 90% in group C (120/134) (chi(2)-test P < 0.01). The incidence of side effects was 9.5% in group A, 9% in group B and 8.2% in group C (chi(2)-test P = 0.1). CONCLUSION This study demonstrates that bovine lactoferrin is an effective adjuvant to 7-day triple therapy for eradication of H. pylori infection.

Abstract
BACKGROUND The mechanisms by which Helicobacter pylori and low-dose aspirin induce gastric damage are not completely elucidated. AIM To evaluate the effects of low-dose aspirin on gastric damage, mucosal prostaglandin-E(2) levels and cyclooxygenase-enzyme expression in relation to the H. pylori status. METHODS Twenty healthy volunteers (H. pylori positive, n = 10; H. pylori negative, n = 10) received aspirin 100 mg/die for 1 week. At days 0, 1, 3 and 7, gastric mucosal lesions were studied by oesophagogastroduodenoscopy and histology. COX-1 and COX-2 were determined by immunohistochemistry and reverse-transcriptase polymerase chain reaction, and mucosal prostaglandin-E(2) levels by enzyme-linked immunosorbent assay. Nine H. pylori-positive subjects repeated the protocol after H. pylori eradication. RESULTS All groups developed a similar number of erosions. COX-1 and COX-2 expression, as well as mucosal prostaglandin-E(2) levels were not influenced by H. pylori status and aspirin medication. Helicobacter pylori-negative and H. pylori-eradicated subjects who developed aspirin-induced erosions had significant lower pre-treatment antral prostaglandin-E(2) levels than those without erosions (3.6 ng/microg vs. 6.3 ng/microg protein and 3.6 ng/microg vs. 6.0 ng/microg protein, respectively, P < 0.01 Mann-Whitney U-test). CONCLUSIONS In healthy subjects, low-dose aspirin for 1 week does neither affect cyclooxygenase expression nor mucosal prostaglandin-E(2) levels. Antral prostaglandin-E(2)-basal levels appear to be critical for development of aspirin-induced gastric damage in subjects without H. pylori infection.

Abstract
BACKGROUND Several tests have been proposed for evaluating dyspeptic symptoms and their relationship to the underlying gastric disease. Serum pepsinogens and gastrin-17 are known to be useful biomarkers for the detection of gastric pathologies. AIM To evaluate the capability of screening dyspeptic patients in the primary care by analyses of serum pepsinogens I (sPGI) and II (sPGII), gastrin-17 (sG-17) and the IgG anti-Helicobacter pylori antibodies (IgG-Hp). PATIENTS AND METHODS Three hundred and sixty-two consecutive patients with dyspeptic symptoms (208 females, mean age 50.6 +/- 16 years, range 18-88 years) referred by general practitioners for upper gastrointestinal endoscopy were enrolled. A blood sample was taken from each subject for IgG-Hp, sPGI, sPGII and sG-17 analyses. RESULTS Two hundred and eighty-seven patients had a complete screening; of these, 132 resulted positive for Hp infection. Patients with atrophic chronic gastritis showed significantly lower serum pepsinogen I levels and sPGI/sPGII ratio than patients with non-atrophic chronic gastritis. Moreover, by calculating the values of sPGI by sG-17 and sG-17 by sPGII/sPGI, subjects with atrophic chronic gastritis could be distinguished from those with non-atrophic chronic gastritis and from those with normal mucosa, respectively. sG-17 levels were found to be a useful biomarker for the detection of antral atrophic gastritis, while the combination of sPGI, the sPGI/sPGII ratio and sG-17 was found effective in identifying corpus atrophy. CONCLUSION A panel composed of PGI, PGII, G-17 and IgG-Hp could be used as a first approach in the 'test and scope' and/or 'test and treat' strategy in the primary care management of dyspeptic patients.

Abstract
Gastroesophageal reflux disease is associated with various otolaryngological disorders. The aim of this retrospective study was to determine the role of gastroesophageal reflux disease in the development of laryngeal squamous cell carcinoma (SCC) in non-smoking and non-drinking patients. The study population consisted of 36 consecutive non-smoking and non-drinking patients with histologically confirmed SCC of the larynx. As a control, a group of 125 lifetime non-smoking and non-drinking cancer-free subjects were selected. Patients with laryngeal cancer had a higher prevalence of gastroesophageal reflux disease than the control subjects (P < 0.0001). Our results confirm the fact that gastroesophageal reflux disease in itself is associated with an increased risk of laryngeal cancer.

Abstract
BACKGROUND Although administration of gastroprotective drugs may reduce the risk of peptic ulcers associated with the chronic use of non-steroidal anti-inflammatory drugs or aspirin, no consensus exists as to whether this co-therapy is effective for short-term prevention, particularly in old age. AIM To evaluate the risk of peptic ulcer associated with acute and chronic non-steroidal anti-inflammatory drugs or aspirin therapy in elderly subjects, and the influence of antisecretory treatment on this risk. METHODS The study included 676 elderly non-steroidal anti-inflammatory drugs or aspirin users and 2435 non-users who consecutively underwent upper gastrointestinal endoscopy. The use of non-steroidal anti-inflammatory drugs and/or aspirin as well as antisecretory drugs (H2-blockers and proton-pump inhibitors) was evaluated by a structured interview. Diagnosis of gastric and duodenal ulcer as well as Helicobacter pylori infection were carried out by endoscopy and histological examination of the gastric mucosa. RESULTS About 47.3% of patients were acute and 52.7% chronic users of non-steroidal anti-inflammatory drugs or aspirin. The risk of peptic ulcer, adjusted for age, gender, H. pylori infection and antisecretory drug use was higher in acute (gastric ulcer: odds ratio, OR = 4.47, 95% CI: 3.19-6.26 and duodenal ulcer: OR = 2.39, 95% CI: 1.73-3.31) than chronic users (gastric ulcer: OR = 2.80, 95% CI: 1.97-3.99 and duodenal ulcer: OR = 1.68, 95% CI: 1.22-2.33). Proton-pump inhibitor treatment was associated with a reduced risk of peptic ulcer in both acute (OR = 0.70, 95% CI: 0.24-2.04) and chronic (OR = 0.32, 95% CI: 0.15-0.67) non-steroidal anti-inflammatory drugs/aspirin users. Conversely, concomitant treatment with H2-blockers was associated with a significantly higher risk of peptic ulcer both in acute (OR = 10.9, 95% CI: 3.87-30.9) and chronic (OR = 6.26, 95% CI: 2.56-15.3) non-steroidal anti-inflammatory drugs/aspirin users than non-users. Proton-pump inhibitor treatment resulted in an absolute risk reduction of peptic ulcer by 36.6% in acute and 34.6% in chronic non-steroidal anti-inflammatory drugs/aspirin users; indeed, the number needed to treat to avoid one peptic ulcer in elderly non-steroidal anti-inflammatory drugs/aspirin users was three both in acute and chronic users. CONCLUSIONS These findings suggest that proton-pump inhibitor co-treatment is advisable in symptomatic elderly patients who need to be treated with non-steroidal anti-inflammatory drugs and/or aspirin for a short period of time.

Abstract
beta-1-3-Glucan synthase activity and its induction by olive mill wastewaters (OMW) was studied in ten fungal strains (Auricularia auricula-judae, Lentinula edodes, Pleurotus eryngii, Stropharia aeruginosa, Agrocybe aegerita, P. pulmonarius, Armillaria mellea, P. ferulae, P. ostreatus, P. nebrodensis). A microtiter-based enzymatic assay on beta-1-3-glucan synthase activity was carried out on all mycelia growth both on the control medium and on OMW. Among the fungi assayed, L. edodes beta-1-3-glucan synthase was highly enhanced in OMW. The main components of OMW, i.e. phenols and lipids, were added separately to the control medium, to highlight the mechanism of L. edodes beta-1-3-glucan synthase induction. A Southern blot analysis and PCR with degenerated primers were carried out to detect the presence of fks1-like genes in these Basidiomycetes. The sequences obtained from the ten Basidiomycota were remarkably similar to fks1 from Filobasidiella neoformans. Spectrofluorimetric and RT-PCR analyses of beta-1-3-glucan synthase were performed on the mycelia of L. edodes. In this fungus, a strong stimulation of beta-1-3-glucan synthase mRNA and protein was recorded in the presence of OMW and phenols.

Abstract
BACKGROUND Authors generally agree that Giant Pancreatic Pseudocysts (> 10 cm) have a lower spontaneous resolution and are more difficult to treat than smaller pancreatic pseudocysts. This study was carried out on two groups of patients with larger and smaller pancreatic pseudocysts (pancreatic pseudocysts > 10 cm versus pancreatic pseudocysts < 10 cm), and aims to establish whether the size of pancreatic pseudocysts is a factor influencing treatment outcomes. PATIENTS AND METHODS In a retrospective study, we examined 71 patients with pancreatic pseudocysts following an episode of acute pancreatitis, which were treated in our hospital from 1980 to 2000. Forty-one (57.5%) patients had a large pancreatic pseudocyst. Most patients underwent invasive treatments: 9 (12.6%) had percutaneous drainage, 37 (52.1%) open surgery and 13 (18.3%) endoscopic cyst gastrostomy. 12 patients (16.9%) of the 71 were cured with medical therapy alone. RESULTS As far as the aetiology of the pancreatitis, location and number of the cysts were concerned, no major differences emerged between the two groups, although large pancreatic pseudocysts followed more severe pancreatitis (P = 0.0005). All giant pancreatic pseudocysts required invasive treatments; 40% of the pancreatic pseudocysts < 10 cm were successfully treated with medical therapy alone. No statistical differences were found regarding hospital mortality, morbidity, recurrence rate and hospital stay among the patients treated invasively. CONCLUSIONS Giant pancreatic pseudocysts more often require invasive therapy due to persistent symptoms or complications. Treatment outcomes do not seem to be influenced by the size of the pancreatic pseudocysts.

Abstract
BACKGROUND Relatives of patients with gastric cancer are at increased risk of developing this disease, especially if they are infected by Helicobacter pylori. Moreover, H. pylori-related atrophic gastritis and hypochlorhydria are well-documented risk factors for noncardia gastric cancer. Serum pepsinogen I (sPGI) and II (sPGII) levels are low in this condition. The aim of our study was to assess by means of a 'Gastropanel' blood test, including sPGI, sPGII, gastrin-17 (G-17) and antibodies anti-H. pylori (IgG-Hp). both functional and morphological features of gastric mucosa in Hp + ve subjects with a family history of gastric cancer. MATERIALS AND METHODS Twenty-five Hp + ve subjects consecutively referred to our department for gastrointestinal complaints, selected as first-degree relatives of patients suffering from gastric cancer, were enrolled in the study and then matched for sex and age with 25 dyspeptic and Hp + ve subjects with no family history of gastric neoplasia. Blood samples were taken for determination of gastropanel in all patients; in addition, antibodies against CagA were analysed. RESULTS No statistically significant differences were detected between the two groups as regards alcohol consumption, coffee intake and smoking habits. Mean sPGI levels in Group A (83.4 +/- 58.4 microg/L) were significantly lower than those in Group B (sPGI 159.5 +/- 80.6 microg/L; P < 0.0001) as well as sPGII (12.5 microg/L = 6.24 versus 20.6 +/- 58 microg/L; P < 0.006). No statistical difference was found between the two groups in relation to G-17 levels, IgG-Hp titres and antibodies against CagA. CONCLUSION First-degree relatives of patients with noncardia gastric cancer affected by H. pylori infection present lower sPGI and sPGII levels, possibly due to the increased frequency of atrophic lesions in these patients.

Abstract
BACKGROUND One-week triple therapy is the most frequently recommended treatment for Helicobacter pylori infection. Eradication rate is satisfactory, nevertheless is advisable to look for more effective therapies. AIM To test the efficacy of a standard triple therapy plus bovine lactoferrin in the eradication of H. pylori infection. PATIENTS AND METHODS One hundred and fifty consecutive H. pylori positive patients, suffering from dyspeptic symptoms were recruited in a 7-day triple therapy open randomised single centre study with rabeprazole, clarithromycin, tinidazole, bovine lactoferrin (group A) or rabeprazole, clarithromycin, tinidazole (group B), or a 10-day therapy with rabeprazole, clarithromycin, tinidazole (group C). H. pylori status was assessed 8 weeks after the end of the treatment by means of a 13C-urea breath test or a H. pylori stool antigen-test. RESULTS Eradication rates (intention to treat/per protocol) were: group A (92.2/95.9%), group B (71.2/72.5%) and group C (70.2/75%). The efficacy of triple therapy added with lactoferrin was significantly higher than other two regimens (p=0.01, intention to treat analysis; p=0.005, per protocol analysis). CONCLUSION These results suggest that lactoferrin tested in the present study was effective in curing H. pylori and could be a new agent to assist the antimicrobials in the eradication of the bacterium.

Abstract
BACKGROUND The cancer risk associated with gastric non-invasive neoplasia (formerly dysplasia) is debated. This prospective long term follow up study investigates the clinicopathological behaviour of non-invasive gastric neoplasia (and related lesions), focusing on the cancer risk associated with each different histological phenotype. PATIENTS AND METHODS A total of 118 consecutive cases (nine indefinite for non- invasive neoplasia; 90 low grade non-invasive neoplasia; 16 high grade non- invasive neoplasia; and three suspicious for invasive adenocarcinoma) with a histological follow up of more than 12 months (average 52 months; range 12-206) were prospectively followed up with a standardised protocol. Patients in whom gastric cancer was detected within 12 months from the initial diagnosis of non-invasive neoplasia were excluded, assuming that invasive carcinoma had been missed at the initial endoscopy procedure. RESULTS Non-invasive neoplasia was no longer detectable in 57/118 cases (48%), was unchanged in 32 (30%), and evolved into gastric cancer in 20 patients (17%). Evolution to invasive adenocarcinoma was documented in both low and high grade non-invasive neoplastic lesions (8/90 low grade; 11/16 high grade) and correlated with histological severity (low versus high grade) at baseline (p<0.001). Seventy five per cent of cancers occurring during the long term follow up were stage I. CONCLUSIONS The risk of invasive gastric cancer increases with the histological grade of the non-invasive neoplasia. Following up non-invasive gastric neoplasia increases the likelihood of gastric cancer being detected in its early stages.

Abstract
BACKGROUND Keratin 8 (K8) and 18 (K18) are the major components of the intermediate filament cytoskeleton of pancreatic acinar cells and play a relevant role in pancreatic exocrine homeostasis. Transgenic mice for K8 have shown to display progressive exocrine pancreas alterations, including dysplasia, loss of acinar architecture, redifferentiation of acinar to ductal cells, inflammation, fibrosis, and substitution of exocrine tissue by adipose tissue. AIM To investigate whether mutations in the keratin 8 gene are associated with chronic pancreatitis. METHODS Mutations in the keratin 8 gene were determined by polymerase chain reaction/restriction fragment length polymorphism in 67 chronic pancreatitis patients and 100 normal controls. Sequence analysis was performed when necessary. RESULTS Glycine-to-cysteine mutations at position 61 (G61C) of the keratin 8 gene were found in six patients (8.9 vs. 0%, p(c) < 0.003, odds ratio = 21.24, confidence interval = 2.74-164.42); none of the controls presented the mutation. No tyrosine-to-histidine mutations at position 53 (Y53H) were detected in any subject. CONCLUSION G61C mutation of the keratin 8 gene, together with other environmental factors and/or genetic factors, could predispose to chronic pancreatitis, by interfering with the normal organization of keratin filaments.

Abstract
Helicobacter pylori infection outcome might depend on genotypic polymorphisms of both the bacterium and the host. We ascertained: (1) the functionality of H. pylori oipA gene; (2) the polymorphism of the hostinterleukin (IL-1beta) gene (-31 C/T) and of the IL-1RN gene (intron 2 VNTR); (3) the association between the above genes and the histological and pathological outcome of H. pylori infection. One hundred and sixty-five H. pylori positive and 137 H. pylori negative subjects (23 gastric adenocarcinoma, 58 peptic ulcer, 221 gastritis) were studied. oipA was sequenced, IL-1beta was RFLP analysed. Antral and body mucosal biopsies were histologically evaluated. Functional oipA genes were correlated with cagA gene; both genes were significantly associated with gastritis activity, peptic ulcer and gastric adenocarcinoma. In these patients heterozygousIL-1RN 1/2 and IL-1beta C/T genotypes were more frequent than in gastritis patients. Intestinal metaplasia was associated with cagA, functional oipA and IL-1RN 2 allele. In conclusion, peptic ulcer and the preneoplastic intestinal metaplasia are associated with H. pylori virulence genes and with IL-1RN 2 host allele. An interplay between bacterial virulence factors and cytokines genotypes, is probably the main route causing H. pylori infection to lead to benign mild disease, benign severe disease or preneoplastic lesions.

Abstract
BACKGROUND The prevalence both of Helicobacter pylori infection and oesophagitis is higher in the elderly, than in adult and young populations. However the relationship between Helicobacter pylori infection and the clinical behaviour of oesophagitis has not yet been clarified. AIM To evaluate the influence of Helicobacter pylori infection on the severity and clinical outcome after treatment of oesophagitis in elderly patients. METHODS A total of 271 elderly patients (134 male, 137 female, mean age = 79.2 years, range 65-96) with grade 1 to 3 oesophagitis were studied. At baseline, the patients were divided into 3 groups according to Helicobacter pylori infection: Group 1 = 88 Helicobacter pylori-negative patients; Group 2 = 59 Helicobacter pylori-positive patients and Group 3 = 124 Helicobacter pylori-positive patients who underwent a one-week proton pump inhibitor-based triple therapy for the eradication of Helicobacter pylori infection. All patients were treated with proton pump inhibitors for two months; patients in Group 3 were also treated for one week with proton pump inhibitors plus two antibiotics. After two months, endoscopy and histology were repeated. RESULTS At baseline, 32.5% of patients were Helicobacter pylori-negative and 67.5% were Helicobacter pylori-positive. No baseline differences in severity of oesophagitis were found between Helicobacter pylori negative and positive patients. After proton pump inhibitor therapy, the complete resolution of oesophagitis was observed in 80.7% of Group 1, 76.3% of Group 2 and 75.8% of Group 3 (p=ns). Dividing patients also according to the severity of oesophagitis, no difference in healing rates between the three Groups were observed. CONCLUSIONS In this elderly population, Helicobacter pylori infection did not influence the severity of oesophagitis at baseline or the response to short-term treatment with proton pump inhibitors. Furthermore, Helicobacter pylori eradication therapy did not influence the healing rate of oesophagitis.

Abstract
No consensus exists as to whether cotherapy is effective in the short-term prevention of severe NSAID-related gastroduodenal damage. The aim of this study was to provide a quantitative systematic review of the efficacy of gastroprotective drugs, such as misoprostol, H2-blockers, and proton pump inhibitors (PPI) in preventing the severe acute NSAID-related gastroduodenal damage. Placebo-controlled randomized clinical trials on the use of misoprostol, H2-blockers, and PPIs as preventative agents published between January 1986 and May 1999 were identified through Medline and reference lists from clinical reviews. Studies on patients or healthy subjects were considered to be eligible for data pooling if they were performed in acute NSAID users (not longer than 30 days) and with at least one endoscopic evaluation during therapy that reported results specifically for gastric and duodenal damage. Risk difference (RD), heterogeneity chi2 test, publication bias assessment and number needed to treat (NnT) were calculated for each meta-analysis by a customized program. Twenty-one trials met the inclusion criteria evaluating a total of 636 healthy subjects and 1904 patients with arthritis randomized to active drug or placebo. The baseline risk of NSAID-related gastric (68% vs 16.6%, P < 0.001) and duodenal (22% vs 8.5%, P < 0.001) damage was higher in healthy subjects compared to patients with arthritis. Meta-analysis demonstrated a significant heterogeneity between trials performed in the two populations (P < 0.0001). In healthy subjects the active drug treatment induced a significant prevention of severe gastric (misoprostol RD = 69%, 95% CI = 60.3-77.7, H2-blocker RD = 38.3%, 95% CI = 17.8-58.9 and PPI RD = 43%, 95% CI = 28.2-57.7) and duodenal damage (misoprostol RD = 22.3%, 95% CI = 13.6-31, H2-blocker RD = 13.2%, 95% CI = 5.2-21.3 and PPI RD = 17.7%, 95% CI = 3.5-31.8). NnT values were, respectively, 1, 3, and 2 for gastric and 4, 8, and 6 for duodenal damage. In patients with arthritis lower RD and higher NnT values were found compared to healthy subjects. In conclusions, cotreatment with gastroprotective drugs for short-term prevention of severe gastroduodenal NSAID-related damage was more effective in healthy subjects than in patients with arthritis; misoprostol and PPIs were more effective than H2-blockers in the prevention of both gastric and duodenal severe damage; more studies need to evaluate the role of short-term prevention in patients with arthritis who require acute NSAID treatment.

Abstract
In the present study we ascertained whether cagA positive and negative H. pylori strains release water soluble products that can influence the production of gastric mucosal cytokines and endocrine (gastrin) or exocrine (pepsinogen C) secretion in 23 H. pylori positive and 19 H. pylori negative patients. Antral biopsies were obtained to classify inflammation, activity, atrophy, intestinal metaplasia and H. pylori density grade. The cagA gene was identified by means of the polymerase chain reaction (PCR) in H. pylori positive colonies after culture of mucosal samples. Three antral biopsies from each patient were incubated with (1.) Water extracts from cagA positive, (2.) Water extracts from cagA negative strains or (3.) H2O (control) at 37 degrees C in a CO2 incubator for 24 hrs. Gastrin, pepsinogen C, IL-1 beta, IL-8, GMCSF, and TNF alpha were measured in the supernatants and mucosal homogenates. H. pylori infection was significantly associated with an increased antral inflammation and activity (chi 2 = 21.7, p < 0.001 and chi 2 = 42.0, p < 0.001), and increased mucosal levels of IL-1 beta, IL-8 and TNF alpha. Water extracts from cagA positive strains enhanced the release of PGC in mucosal biopsy supernatants (p < 0.05) when patients were considered overall and the release of TNF alpha (p < 0.05) when only patients with duodenal ulcer were considered. Water extracts from cagA negative strains stimulated gastrin secretion (p < 0.05). None of the remaining cytokines were influenced by H. pylori water extracts. In conclusion, pepsinogen C and TNF alpha can be induced by cagA positive water extracts and may contribute to damage the gastric and duodenal mucosa. Our findings indicate that in patients with H. pylori infection the increase of the mucosal levels of IL-1 beta and IL-8 does not depend on H. pylori water soluble products, but probably depends on the entire bacterium.

Abstract
UNLABELLED The aim of the study was to ascertain whether there is an association between the presence of serum parietal cell autoantibodies (PCA) and: (1) Helicobacter pylori infection; (2) the presence and degree of gastritis and intestinal metaplasia; and (3) the H. pylori infecting strain. Gastric mucosal biopsies were obtained from 49 consecutive patients in order to assess and grade gastritis, make a histological diagnosis, and culture and genotype H. pylori. H. pylori infection was present in 26 patients (group 1), had been present in 17 patients (group 2), and the remaining 6 (group 3) had never had the infection. The infecting strain was cagA positive in 21 of 26 group 1 patients. Positive PCA results were found in 84%, 76%, and 14% of patients in groups 1, 2, and 3, respectively. PCA results were correlated with anti-H. pylori antibody titers (P<0.05). In group 2 patients, PCA were associated with the degree of antral gastritis (Fisher's exact test P<0.05). cagA status was not associated with the presence of PCA (chi2=0.68, NS). The frequency of positive findings for PCA in group 2 was higher in patients with (90%) than in those without (50%) intestinal metaplasia. IN CONCLUSION (1) H. pylori infection is associated with the production of PCA, which, after eradication of the infection, persist and might contribute to the persistent antral chronic gastritis and intestinal metaplasia; (2) the gastric lesions associated with infections sustained by the more-virulent H. pylori strains do not appear to be due to the induction of antigastric autoantibodies.

Abstract
BACKGROUND Advancing age may influence clarithromycin's pharmacokinetics. No studies have yet compared the effects of different dosages of clarithromycin in combination with a proton pump inhibitor and amoxicillin in elderly patients. AIM To compare the efficacy and tolerability of clarithromycin 250 mg vs. clarithromycin 500 mg twice daily (b.d.) in combination with pantoprazole and amoxicillin in elderly patients. METHODS One hundred and fifty-four elderly patients with H. pylori-associated ulcer disease or chronic gastritis were consecutively randomized to receive pantoprazole 40 mg daily plus amoxicillin 1 g, and either clarithromycin 250 mg b.d. (PAC 250) or clarithromycin 500 mg b.d. (PAC 500). Two months after therapy, endoscopy and gastric biopsies were repeated. RESULTS The cure rates of H. pylori infection in the PAC 250 and PAC 500 groups were, respectively, 83% and 79% (ITT analysis) and 94% and 88% (PP analysis) (P=N.S.). Significant decreases in chronic gastritis activity both in the body (P < 0.00001) and the antrum (P < 0.0001) of the stomach were found in H. pylori-cured patients, independently of clarithromycin dosage. Four patients in PAC 250 (5%) and seven in PAC 500 (9%) reported adverse events (P=N.S.). One patient in PAC 250 (25%) and three in PAC 500 (43%) discontinued the study because of these drug-related side-effects (P=N.S.). CONCLUSIONS In elderly patients, 1-week triple therapy with a proton pump inhibitor, amoxicillin and clarithromycin is a highly effective and well tolerated anti-H. pylori treatment. With this combination, clarithromycin at the lower dose of 250 mg b.d. achieved excel- lent cure rates and minimized adverse events and costs.

Abstract
BACKGROUND/AIMS Barrett's oesophagus complicates the gastro-oesophageal acid reflux. Helicobacter pylori infection, particularly with cagA positive strains, induces inflammatory/atrophic lesions of the gastric mucosa, which may impair acid output. No systematic study has investigated the phenotype of the gastric mucosa coexisting with Barrett's oesophagus. This study was designed to identify the phenotype of gastric mucosa associated with Barrett's oesophagus. METHODS In this retrospective case control study, the phenotype of the gastric mucosa was histologically characterised in 53 consecutive patients with Barrett's oesophagus and in 53 (sex and age matched) non-ulcer dyspeptic controls. Both patients and controls underwent extensive sampling of the gastric mucosa (two antral, one incisural, and two oxyntic biopsies). Intestinal metaplasia (IM) was categorised (type I, complete IM; types II and III, incomplete IM) by the high iron diamine stain; cagA status was ascertained by genotyping. RESULTS Helicobacter pylori was present in 19 of the 53 patients with Barrett's oesophagus and in 30 of the 53 controls (p < 0.02); eight of the 19 patients with Barrett's oesophagus and 28 of the 35 controls harboured cagA positive H pylori (p < 0.03). The histological severity of non-atrophic gastritis detected in the controls was significantly higher than that detected in the patients with Barrett's oesophagus (p < 0.0001). Multifocal atrophic gastritis was present in 4% of the patients with Barrett's oesophagus and in 23% of controls (p < 0.01). The odds ratio for the association between multifocal atrophic gastritis and Barrett's oesophagus was 0.20 (95% confidence interval, 0.006 to 0.60). Gastric IM was detected in 13.2% of the patients with Barrett's oesophagus and in 30.1% of the controls (p < 0.03). Type III IM at the gastric mucosa was only detected among controls. CONCLUSIONS Barrett's oesophagus is associated with a low prevalence of H pylori cagA positive infection and multifocal atrophic gastritis. This pathobiological pattern is considered to be associated with a low risk of distal gastric cancer.

Abstract
UNLABELLED Several diagnostic assays are available for evaluating Helicobacter pylori infection: histological examination, culture of gastric biopsies, urea breath test and serology. Recently a new enzyme immunoassay has been introduced for the detection of H. pylori antigens in stool samples (HpSA). The aim of our study was to evaluate and compare diagnostic efficacy of HpSA with histological examination, culture, urea breath test and serology in a group of 95 patients. Patients were classified H. pylori positive (43) or negative (52) on the basis of histology, culture and urea breath test. HpSA optical densities were significantly higher in infected patients compared to those obtained in H. pylori-negative patients (t = 5.47, p < 0.001). Overall, with a fixed cut-off of 0.1 unit of optical density, the sensitivity was 79% and the specificity 100%. In the H. pylori positive patients, HpSA optical density correlated with bacterial load histologically evaluated in the gastric antrum (r = 0.405, p < 0.05) and was inverse correlated with levels of serum IgG elicited against H. pylori (r = -0.315, p < 0.05). Considering patients with a positive HpSA finding and/or levels of anti-H. pylori antibodies upper than 30 U/mL, sensitivity in detecting infected patients was 98%. IN CONCLUSION (1) immunodetection of H. pylori antigens in stools is a good alternative of breath test; (2) a reduction in H. pylori density grade might be accompanied by low HpSA optical density, leading to a false negative result and (3) combining the HpSA determination with the serum detection of anti-H. pylori antibodies a better clinical sensitivity is obtained.

Abstract
BACKGROUND Incidence of adenocarcinoma of distal oesophagus and gastric cardia, probably arising from areas of intestinal metaplasia, has been increasing rapidly. AIMS To define prevalence of intestinal metaplasia of distal oesophagus, oesophagogastric junction and gastric cardia and to evaluate potential associated factors, by means of a prospective multicentre study including University and teaching hospitals, and primary and tertiary care centres. PATIENTS Each of 24 institutions involved in study enrolled 10 consecutive patients undergoing first-time routine endoscopy for dyspeptic symptoms. METHODS Patients answered symptom questionnaires and underwent gastroscopy Three biopsies were taken from distal oesophagus, oesophago-gastric junction and gastric cardia, and were stained with haematoxylin and eosin. Specimens were also evaluated for Helicobacter pylori infection. RESULTS A total of 240 patients (124 male, 116 female; median age 56 years, range 20-90) were enrolled in study. Intestinal metaplasia affected distal oesophagus in 5, oesophago-gastric junction in 19 and gastric cardia in 10 patients. Low-grade dysplasia was found at distal oesophagus and/or oesophago-gastric junction of 3/24 patients with intestinal metaplasia vs 2/216 without intestinal metaplasia (p<0.05). A significant association was found between symptoms and presence of intestinal metaplasia, regardless of location, and between Helicobacter pylori infection and intestinal metaplasia at oesophago-gastric junction. CONCLUSIONS Intestinal metaplasia of distal oesophagus, oesophagogastric-junction and gastric cardia is found in a significant proportion of symptomatic patients undergoing gastroscopy and is associated with dysplasia in many cases. Although prevalence of dysplasia seems to decrease when specialized columnar epithelium is found in short segment, or even focally in oesophago-gastric junction, these small foci of intestinal metaplastic cells may represent source of most adenocarcinomas of cardia.

Abstract
AIMS To evaluate prevalence of primary Helicobacter pylori antibiotic resistances in Northeast Italy and to identify risk factors associated with this resistance. MATERIALS AND METHODS A total of 248 patients undergoing upper gastrointestinal endoscopy were enrolled from 19 Endoscopy Units over a 6-month period. From each patient, 4 gastric biopsies were taken for histology and 2 were sent to the Central Referral Microbiological Laboratory for culture and determination of antibiotic activity against Helicobacter pylori by means of E-test. Strains were considered resistant when minimum inhibitory concentration was >8 microg/ml for metronidazole and >1 microg/ml for clarithromycin. No cut-off value was predefined for amoxycillin. RESULTS Culture of Helicobacter pylori was successfully performed in 167 patients. Primary resistance to metronidazole, clarithromycin or amoxycillin was 14.9%, 1.8% and 0%, respectively Patients infected with Helicobacter pylori strains resistant to antibiotics were more frequently females than males (70.3% vs 41.4%), had a significantly lower coffee intake (66.6% vs 86.6%) and lower body mass index (23.7+/-2.6 vs 25.3+/-3.6) than patients with susceptible Helicobacter pylori strains. Age, smoking, alcohol use, family history of Helicobacter pylori infection, concomitant diseases and treatments, endoscopic diagnoses, Helicobacter pylori density and histological activity of chronic gastritis were not associated with antibiotic resistance. Multivariate analysis confirmed that female gender (odds ratio = 2.74, 95% confidence interval = 1.03-7.27) was the only significant risk factor associated with antibiotic resistance. CONCLUSIONS In this population, primary Helicobacter pylori resistance to metronidazole was higher than resistance to clarithromycin, and female gender was significantly associated with this resistance. The low prevalence of resistance to metronidazole, clarithromycin and amoxycillin identified in this geographical area suggests that proton pump inhibitor-based triple regimens including these antibiotics may still be used as first line therapies against Helicobacter pylori infection.

Abstract
BACKGROUND Antibiotic-resistant Helicobacter pylori strains are becoming increasingly prevalent, although it is not clear to what extent the new resistant organisms will spread. AIM To evaluate the incidence of secondary Helicobacter pylori resistance to metronidazole, clarithromycin and/or amoxycillin after one-week proton pump inhibitor based triple therapy failure in patients who were, before therapy infected with Helicobacter pylori strains susceptible to these antibiotics. PATIENTS AND METHODS Enrolled in the study were 97 consecutive Helicobacter pylori-positive subjects infected by Helicobacter pylori strains susceptible to metronidazole, clarithromycin and amoxycillin. Activity of tested antibiotics was determined by means of the E-test. Patients were treated for seven days with a proton pump inhibitor, omeprazole 20 mg twice daily or pantoprazole 40 mg once daily, plus clarithromycin 250 mg twice daily and metronidazole 250 mg four times daily; or with a proton pump inhibitor plus amoxycillin 1 g twice daily and clarithromycin 500 mg twice daily. Two months after completion of therapy, endoscopy and gastric biopsies for histology, rapid urease test and culture were repeated. RESULTS Four patients were dropped from the study Overall Helicobacter pylori cure rates expressed as both intention-to-treat and per-protocol analyses, were, respectively 80% (40/50) and 81.6% (40/49) with proton pump inhibitor, clarithromycin and metronidazole and 76.6% (36/47) and 81.8% (36/44) with proton pump inhibitor amoxycillin and clarithromycin. No significant differences were observed between the two treatments. Subjects in whom treatment failed were significantly younger and had less active ulcer than cured patients. Of treatment failures, 70.6% (12 out of 17 subjects) de veloped a secondary resistance to metronidazole (35.33% and/or clarithromycin (64.7%). Secondary antibiotic resistance occurred in 77. 8% of treatment failures treated with proton pump inhibitor, clarithromycin and metronidazole and in 62.5% of those treated with proton pump inhibitor, amoxycillin and clarithromycin. Considering all patients treated, the overall incidence of secondary metronidazole and/or clarithromycin resistance after therapy was reported in 12.9% of subjects (12 out of 93 treated patients). CONCLUSIONS Secondary Helicobacter pylori resistances to metronidazole and/or clarithromycin occurred in large percentages in patients with treatment failure after the one-week proton pump inhibitor-based triple therapies, proton pump inhibitor, clarithromycin and metronidazole and proton pump inhibitor, amoxycillin and clarithromycin. It is likely that new antibiotics or treatment strategies will be needed in the near future to successfully treat Helicobacter pylori infection.

Abstract
The objective of this study was to evaluate the long-term efficacy of Helicobacter pylori (HP) eradication treatment in elderly patients with HP-associated peptic ulcer. A total of 56 subjects, 25 affected with gastric ulcer (GU, 9 males, 16 females, mean age 77.8 years, range 67-93) and 31 with duodenal ulcer (DU, 19 males, 12 females, mean age 76.5 years, range 65-87) were confirmed to be HP-positive by gastric histology and the rapid urease test. All patients were then consecutively treated with omeprazole for 4 weeks plus one or two antibiotics for 1 week as anti-HP treatment. Clinical checkups were then performed every 3 months for 1 year for the evaluation of symptoms and clinical recurrences. Endoscopy with gastric biopsies was repeated after 1, 3 and 12 months for the evaluation of ulcer healing, HP infection and chronic gastritis activity. Statistical analysis was performed by means of the Student t test for unpaired data, the Fisher exact test (two-tailed), and the McNemar chi 2 test. After 4 weeks of treatment, endoscopy confirmed healing of the ulcer in all patients, regardless of the treatment used to cure HP infection. Two months after the end of therapy, a total of 44 patients were HP-negative and 12 patients were still HP-positive. During the 1-year follow-up period 1/44 (2.2%) of the HP-eradicated patients and 5/12 (41.6%) of the still HP-positive patients suffered relapses (p = 0.001): the difference between the two groups remained statistically significant when patients were divided into the subgroups, GU (p = 0.01) and DU (p = 0.04). Two months after the end of therapy, there was still a significant reduction of symptoms both in HP-eradicated (p < 0.0000) and in HP-positive (p = 0.002) patients. After 1 year, however, there was a significantly decreased symptomatology only in HP-eradicated subjects (p < 0.0000) and not in patients still HP-positive. After both 2 months and 1 year of follow-up, chronic gastritis activity demonstrated a significant improvement only in HP-eradicated patients (p = 0.0000). In conclusion, the eradication of HP infection significantly improved the long-term clinical outcome of peptic ulcer disease in the elderly, reducing the recurrences of GU and DU, the patient's symptomatology and the histological signs of chronic gastritis activity. The cure of HP infection is, therefore, strongly recommended in elderly patients with HP-associated peptic ulcer disease.

Abstract
AIM To compare the efficacy of pantoprazole vs. a one-week Helicobacter pylori eradication therapy for the prevention of NSAID-related gastroduodenal damage. METHODS Patients over 60 years old with symptoms and/or a history of ulcer who needed NSAID treatment were evaluated by endoscopy. H. pylori positive subjects who had no severe gastroduodenal lesions were randomized to take, concomitantly with NSAID therapy, either: (i) pantoprazole 40 mg daily plus amoxycillin 1 g b.d. and clarithromycin 250 mg b.d. for 1 week (35 subjects, Group PAC) or (ii) pantoprazole 40 mg daily for 1 month (34 subjects, Group P). Endoscopy was repeated after 1 month. RESULTS A significantly higher incidence of severe gastroduodenal damage was found in Group PAC than in Group P (29% vs. 9%, P<0.05). The percentages of patients worsened, unchanged and improved after 1 month were, respectively: Group PAC: 46%, 46%, and 9% and Group P: 7%, 65%, and 29% (P<0.0008). The percentage of H. pylori-negative subjects was 89% in Group PAC and 52% in Group P (P=0.0009). The incidence of gastroduodenal damage was higher in Group PAC treatment failures than in cured patients (50% vs. 25.8%, P=ns). CONCLUSION One month of pantoprazole was more effective than a proton pump inhibitor-based triple therapy in the prevention of gastroduodenal damage in elderly H. pylori-positive NSAID users.
