Interleukin-1 gene polymorphisms and gastric cancer risk in a high-risk Italian population.
OBJECTIVES:
Host genetic factors, including the IL1 gene cluster, play a key role in determining the long-term outcome of Helicobacter pylori infection. The aim of the study was to investigate the relationship between selected IL1 loci polymorphisms and gastric cancer risk in an Italian population.
METHODS:
In a case-control study we compared the IL1B-31 and IL1B+3954 biallelic and IL1RN pentaallelic variable number of tandem repeats (VNTR) polymorphisms in 185 gastric cancer patients and 546 controls randomly sampled from the general population of an area at high gastric cancer risk (Tuscany, Central Italy).
RESULTS:
Genotype frequencies of the IL1B-31 T/C, IL1B+3954 C/T, and IL1RN polymorphisms among our population controls were in Hardy-Weinberg equilibrium. In multivariate analyses, no increase in gastric cancer risk was observed for the IL1B-31*C- and IL1B+3954*T- carriers; a significant 50% increase emerged for IL1RN*2 allele carriers (OR = 1.49; 95% CI: 1.01-2.21). Analyses based on combined genotypes showed also that the association with IL1RN*2 allele was limited to two-variant allele carriers who were also homozygous for the IL1B-31*T allele (OR = 2.23; 95% CI: 1.18-4.23) with a statistically significant interaction between these two genotypes (p= 0.043). Haplotype analysis showed an increased risk for the haplotype IL1RN*2/IL1B-31*T.
CONCLUSIONS:
Our results suggest that host genetic factors (such as the IL1RN and the IL1B-31 polymorphisms) interact in the complex process of gastric carcinogenesis in this high-risk Italian population. Overall, this effect appears more modest than previously reported in other populations, supporting the hypothesis that other still-to-be-defined factors are important in gastric carcinogenesis. These findings might be due to a haplotype effect

Long term outcome of acute pancreatitis in Italy: Results of a multicentre study
Background: In Italy, no long-term studies regarding the natural history of acute pancreatitis have been carried out. Aim: To report the results of a follow-up on a large series of patients hospitalised for pancreatitis. Methods: Data of 631 patients admitted to 35 Italian hospitals were retrospectively evaluated 51.7 ± 8.4 months after discharge. Results: The average recovery time after mild or severe pancreatitis was 28.2 and 53.4 days respectively. Fourteen sequelae were not resolved and 9 cases required late surgical intervention. Eighty patients (12.7%) had a second hospital admission. Of the patients with mild biliary pancreatitis, 67.9% underwent a cholecystectomy. The overall incidence of relapse was 12.7%. Mortality was 9.8% and no death was related to pancreatitis. Three patients died from carcinoma of the pancreas. Conclusion: Reported recovery time after an attack of pancreatitis was longer than expected in the mild forms. The treatment of sequelae was delayed beyond one year after discharge. The incidence of relapse of biliary pancreatitis in patients not undergoing a cholecystectomy was low, due to endoscopic treatment. Mortality from pancreatic-related causes is low, but there is an association with malignant pancreatic or ampullary tumours not diagnosed during the acute phase of the illness. © 2013 Editrice Gastroenterologica Italiana S.r.l

A prospective multicentre survey on the treatment of acute pancreatitis in Italy
Background: The Italian Association for the Study of the Pancreas released a diagnostic and therapeutic algorithm for acute pancreatitis in 1999. Aim: This study focused on the analysis of the therapeutic approach for the treatment of acute pancreatitis in Italy. Patients: One thousand, one hundred and seventy-three patients were recruited: 1006 patients (85.8%) had mild acute pancreatitis (MAP) and 167 (14.2%) had the severe acute pancreatitis (SAP); 161 patients showed pancreatic necrosis at computed tomography; 121 patients (10.3%) had sequelae and 36 (3.1%) died. Results: Non-steroidal anti-inflammatory drugs and tramadol were used more frequently in patients with the MAP whereas opioids and the association schedules were used more frequently in patients with the SAP (P < 0.001). Gabexate mesilate was utilised in 831 out of 1173 patients (70.8%); in particular, gabexate mesilate was used in 70.6% patients with MAP and in 73.1% of those with SAP (P = 0.521). The duration of the drug administration was significantly shorter in those having MAP than in those having the SAP (P < 0.001). The antibiotics most frequently used for the prophylaxis against infection from pancreatic necrosis (43.1%) were carbapenems. Only a small number of patients received enteral nutrition (4.7%). Endoscopic retrograde cholangiopancreatography was carried out in 344 of the 1173 patients (29.3%). Surgery was performed in 48 with SAP (19 had elective biliary surgery and 29 had pancreatic surgery). Conclusions: The results of this survey indicate a lack of compliance with the guidelines which regard the indications mainly for interventional endoscopy and surgery. \ua9 2007 Editrice Gastroenterologica Italiana S.r.l
Diagnostic assessment and outcome of acute pancreatitis in Italy: Results of a prospective multicentre study. ProInf-AISP: Progetto informatizzato pancreatite acuta, Associazione Italiana Studio Pancreas, phase II
Background and aim: Up till now, only one study providing practically complete information on acute pancreatitis in Italy has been published. The aim of this prospective study was to evaluate the clinical characteristics, in terms of diagnostic assessment and outcome, of a large series of patients affected by acute pancreatitis in Italy. Materials and methods: The study involved 56 Italian centres, homogeneously distributed throughout the entire national territory. Each participating centre was furnished with an ad hoc software including 530 items along with subsequent collection, tabulation and quality control of the data. Results: One thousand five hundred and forty case report forms of patients affected by acute pancreatitis were collected but 367 of them (24%) were subsequently eliminated from the final analysis. Therefore, 1173 patients (581 females and 592 males) were recruited. Mean age of patients was 62.0 \ub1 18.2 years (95% confidence interval, 60.9-63.0). On the basis of Atlanta classification, 1006 patients (85.8%) were defined as mild and 167 (14.2%) as severe pancreatitis. Biliary forms represented the most frequent aetiological category (813 cases, 69.3%) while alcoholic forms only 6.6% (77 cases); the remaining aetiologies accounted for 7.1% (83 cases) while 200 cases (17.1%) remained without a definite aetiological factor. Complete recovery was achieved in 1016 patients (86.6%) whereas morphological sequelae were found in 121 patients (10.3%) and mortality in 36 patients (3.1%; 0.4% in mild and 19.2% in severe acute pancreatitis). Ultrasonography was largely utilised as a first line diagnostic tool in all patients, with valuable visualisation of the pancreas in 85% of patients. Computer tomography scan was also widely used, with 66.7% of exams in mild and 33.3% in severe pancreatitis. Patients affected by biliary pancreatitis presented more severe (p = 0.004) and necrotizing forms (p = 0.021). Mortality was significantly related (p < 0.001) with the extension of pancreatic necrosis and with an age of over 70 years. Body mass index presented significantly greater values in severe than in mild forms (p < 0.001). Conclusions: Association of creatinine serum level over 2 mg/dl with an abnormal chest X-ray showed a high significant correlation with a more severe outcome in terms of morphological sequalae and mortality (p = 0.0001). Acute pancreatitis in Italy more commonly presents biliary aetiology and favourable outcome with low rate of complications and mortality. From a cost-effectiveness standpoint, diagnostic approach to this disease needs to be better standardised. \ua9 2007
