ABSTRACT

BACKGROUND: This was a prospective observational study designed to evaluate direct and indirect costs and quality of life for patients with Crohn's disease in Italy from the perspectives of the National Health System and of society. METHODS: A total of 162 male and female subjects aged 18-70 years with Crohn's disease in the active phase and a Crohn's Disease Activity Index score ≥150 were included in the study. Subjects were recruited from 25 Italian centers on a consecutive basis. The study consisted of four visits undertaken every 6 months with a follow-up period of 18 months. The study started on September 1, 2006 and was completed on April 12, 2010. Multivariate analyses were carried out on demographic characteristics, treatment costs based on the prescribed daily dose, resource use and other cost parameters, and changes in quality of life using the EQ5D questionnaire. RESULTS: Cost of illness per subject with Crohn's disease in Italy was estimated to be €15,521 per year, with direct costs representing 76% of total costs. Nonhealth care costs and loss of productivity accounted for 24% of total costs. Societal costs during the first months of enrolment were higher compared with costs in the final months of the study. Quality of life measured by the EQ-5D was 0.558 initially and then increased to 0.739, with a mean value of 0.677 during the enrolment period. The cost of illness was not correlated with age or gender. CONCLUSION: The cost of illness was correlated with quality of life; Crohn's disease had a negative impact on subjects' quality of life, and higher costs corresponded to a lower quality of life as measured with the EQ5D. Drug treatment may improve quality of life and reduce hospitalization costs. Our results appear to be in line with the results of other international cost-of-illness studies.

ABSTRACT

OBJECTIVES: We sought (i) to validate a new prediction rule of mortality (Progetto Nazionale Emorragia Digestiva (PNED) score) on an independent population with non-variceal upper gastrointestinal bleeding (UGIB) and (ii) to compare the accuracy of the Italian PNED score vs. the Rockall score in predicting the risk of death. METHODS: We conducted prospective validation of analysis of consecutive patients with UGIB at 21 hospitals from 2007 to 2008. Outcome measure was 30-day mortality. All the variables used to calculate the Rockall score as well as those identified in the Italian predictive model were considered. Calibration of the model was tested using the chi2 goodness-of-fit and performance characteristics with receiver operating characteristic (ROC) analysis. The area under the ROC curve (AUC) was used to quantify the diagnostic accuracy of the two predictive models. RESULTS: Over a 16-month period, data on 1,360 patients were entered in a national database and analyzed. Peptic ulcer bleeding was recorded in 60.7% of cases. One or more comorbidities were present in 66% of patients. Endoscopic treatment was delivered in all high-risk patients followed by high-dose intravenous proton pump inhibitor in 95% of them. Sixty-six patients died (mortality 4.85%; 3.54-5.75). The PNED score showed a high discriminant capability and was significantly superior to the Rockall score in predicting the risk of death (AUC 0.81 (0.72-0.90) vs. 0.66 (0.60-0.72), P<0.000). Positive likelihood ratio for mortality in patients with a PNED risk score >8 was 16.05. CONCLUSIONS: The Italian 10-point score for the prediction of death was successfully validated in this independent population of patients with non-variceal gastrointestinal bleeding. The PNED score is accurate and superior to the Rockall score. Further external validation at the international level is needed.

ABSTRACT

The agreement between Italian and Japanese endoscopists and pathologists on endoscopic and histopathological diagnoses of superficial gastric lesions is verified with the use of Paris and Vienna classifications. The correlations between Paris endoscopic types and Vienna histopathological categories is high in both the independent Italian and Japanese evaluations. However, the agreement between Italian and Japanese endoscopists is moderate due to the difficult evaluation of the height of the lesions, in particular when they are mixed. The agreement on the size of the lesions is fairly good. The probability of the same allocation to the Vienna categories of a single case is 87 per cent, disagreements remaining in dysplasia grading, between dysplasia, not only high-grade but also low-grade, and in situ carcinoma, and on cancer invasion of the lamina propria. The results indicate that use of the Paris and Vienna classifications has reduced the discrepancies between Western and Japanese endoscopists and pathologists in the diagnosis of these lesions.
