A four-day low dose triple therapy regimen for the treatment of Helicobacter pylori infection.

OBJECTIVE: The current guidelines recommend 1-wk triple therapy regimens for eradicating H. pylori infection. Until now, shorter regimens have scarcely been investigated. Azithromycin is a new generation macrolide antibiotic with unusual and favorable pharmacokinetics, and seems to be a very promising agent for innovative anti-H. pylori regimens. We assessed the efficacy and tolerability of a new 4-day low dose triple therapy in comparison with a well established 1-wk triple therapy in the treatment of Helicobacter pylori infection. METHODS: One hundred-sixty consecutive patients with biopsy-proven H. pylori infection were randomized to receive lansoprazole 30 mg b.i.d. on days 1-4, azithromycin 500 mg u.i.d. on days 2-4, and tinidazole 2000 mg u.i.d. on day 3 (LAT group), or 7 days of triple therapy of omeprazole 20 mg u.i.d., clarithromycin 250 mg b.i.d., and tinidazole 500 mg b.i.d. (OCT group). Patients with gastric or duodenal active ulcer received proton pump inhibitors for an additional 4 wk. H. pylori eradication was defined as negative of both rapid urease test and histology on biopsies taken from the gastric body and antrum at least 1 month after the end of treatment. RESULTS: Seven patients in the LAT group and four in the OCT group were lost to follow-up. No significant difference in either efficacy or tolerability was observed between the two regimens. Active ulcers healed in 97.8% of cases with LAT and in 100% of cases with OCT. The eradication rate was 80.8% in the LAT group and 85.5% in the OCT group, considering the per-protocol results, and 73.3% and 81.2%, respectively, considering the intention-to-treat results. Side effects occurred in one LAzT patient and in two OCT patients; they were mild and did not interfere with compliance. CONCLUSION: The new proposed ultrashort triple therapy, including lansoprazole, low dose azithromycin for 3 days, and a single dose of tinidazole, appears to be a very effective anti-H. pylori regimen, a simpler, cheaper, well-tolerated, and equally effective alternative to 1-wk triple therapy

Evaluation of a new ultrashort triple therapy for Helicobacter pylori disease.

BACKGROUND: 1-week proton pump inhibitor-based triple therapies are considered the most effective and convenient drug combinations for curing Helicobacter pylori infection. Short therapies, lasting less than 1 week have been investigated rarely. AIM: To assess the efficacy and tolerability of a 3-day lansoprazole triple therapy after 1 day of lansoprazole pre-treatment. METHODS: Seventy H. pylori-positive (rapid urease test and histology) patients received LAzT3 regimen (lanzoprazole 30 mg b.d. and azithromycin 500 mg o.m. for 3 days; tinidazole 2000 mg o.m. on day 1 and 1000 mg o.m. on days 2-3) after 1 day of lansoprazole pretreatment. Patients with active ulcer received lansoprazole 30 mg o.m. for an additional 4 weeks. Follow-up gastroscopy was carried out 4-6 weeks after completion of therapy. Eradication was defined as negative histology and rapid urease test. RESULTS: Four patients failed to attend the follow-up endoscopy. One patient complained of minor side-effects. H. pylori was eradicated in 57 of 66 patients suitable for evaluation, with a per-protocol cure rate of 86.3% (95%CI: 76-94%), and an intention-to-treat cure rate of 81.4% (95%CI: 70-90%). CONCLUSIONS: This new ultrashort triple therapy including lansoprazole, azithromycin and tinidazole seems to be effective in eradicating H. pylori. It is safe and well-tolerated, and may be taken into consideration as a valid alternative to the better known and widely used 1-week proton pump inhibitor-based triple therapies

Costo sociale annuo della dispepsia funzionale dopo l'eradicazione dell'Helicobacter pylori : risultati di un'indagine in centri di endoscopia digestiva

Objective: The aim of this study was to evaluate socio-demographic and clinical characteristics of dyspeptic patients in Italy after the eradication of Helicobacter pylori infection and to evaluate the impact of this syndrome on daily activities, on loss of production, and, finally, to estimate its cost for both National Health Service and society. Design: An observational, prospective, one-year, multicenter study was conducted from April 1999 to April 2002 under the aegis of the Italian study group of digestive tract motility (GISMAD). The study was based on 577 consecutive functional dyspeptic patients after eradication of H. pylori. Data were collected by a Case Report Form (CRF). Setting: 91 Centres of Digestive Endoscopy (CED), all located in Italy. Results: The mean age of the 577 dyspeptic patients enrolled in the study was 52 yrs.\ub114 (13.3% was younger than 40 yrs old; mostly females: 56.7%). Sixty point seven percent of patients met expenses related with the treatment of dyspepsia. Patients were stratified into four groups according to their prevalent symptoms: ulcer-like (UL), dismotility-like (DL), reflux-like (RL) and 'other'. Annual mean cost estimated for each patient was \u20ac 145.54, with differences between females and males ( \u20ac 168.95 vs \u20ac 114.91 respectively). "RL" patients resulted at the highest cost (\u20ac 204.32). Total costs were divided into health related costs (\u20ac 60.87) and loss of productivity (\u20ac 84.67), the latter being mostly related absences (21%). Conclusions: During a follow-up period of 12 months, in each group there was a clear evidence of both a reduction of negative influence of dyspeptic symptoms on the patients' activities and a decrease of the mean cost for the treatment of dyspepsia. "RL" group presents cost 30% higher when compared with "UL" and "DL" groups, and 90% higher when compared with "other"

HCV infection is a risk factor for gallstone disease in liver cirrhosis: An Italian epidemiological survey

We assessed the prevalence of gallbladder disease (i.e. gallstones plus cholecystectomy) among patients with liver disease and its association with the severity and aetiology of hepatic injury. Subjects, referred to 79 Italian hospitals, were enrolled in a 6-month period. The independent effect of the severity and aetiology of liver disease on gallstone disease prevalence was assessed by multiple logistic regression analysis. Overall, 4867 subjects tested anti-hepatitis C virus (HCV) positive alone, 839 were hepatitis B virus surface antigen (HBsAg) alone, and 652 had an excessive alcohol intake. The prevalence of gallstone disease was 23.3% in anti-HCV-positive patients, 12.4% in HBsAg positive and 24.2% in subjects reporting excessive alcohol intake, respectively. Gallstone disease prevalence increased by age in each aetiological category. The proportion of patients with gallstone disease who had a cholecystectomy was the highest in HCV+ subjects. After adjusting for the confounding effect of age and body mass index, compared with patients with less severe liver disease, subjects with HCV-related cirrhosis, but not those with alcohol-related cirrhosis, were more likely to have gallstone disease. Subjects with HCV-related cirrhosis (OR 2.13, 95% CI: 1.38-3.26) were more likely to have gallstone disease when compared with those with HBV-related cirrhosis. HCV infection is a risk factor for gallstone disease. In Italy, the high prevalence of HCV infection among cirrhotic patients has important implications, as cholecystectomy in these subjects is associated with high risk of morbidity and mortality. \uc2\ua9 2007 The Authors

Characteristics of HCV positive subjects referring to hospitals in Italy: a multicentre prevalence study on 6,999 cases

In 2001, 6 999 anti-HCV positive subjects referred to 79 Italian hospital in a 6 months enrolment period were evaluated. Of them, 5 632 (80.5%) tested anti-HCV positive alone, 1 163 (16.6%) reported also an excessive alcohol intake, and 204 (2.9%) were also HBsAg positive. Normal biochemistry was observed in 7.8% of cases, chronic hepatitis in 67.9% of cases, liver cirrhosis in 18.9% of cases, and hepatocellular carcinoma in 3.6% cases. HCV positive subjects with excessive alcohol intake were statistically significantly younger, of male sex, and having more severe liver disease than those without excessive alcohol intake. Adjusting for the confounding effect of age and sex by multiple logistic regression analysis, HCV positive chronic hepatitis cases drinking more than four alcoholic drinks daily were 2.2-fold (CI 95% = 1.3-4.0) more likely to progress to liver cirrhosis than teetotallers. These findings indicate that nearly a quarter of HCV positive subjects referred to hospitals in Italy have a severe liver disease causing a remarkable impact on the national health system. Excessive alcohol intake in HCV chronic hepatitis cases increases the risk of progression to liver cirrhosis. © 2005 Blackwell Publishing Ltd

The importance of HCV on burden of chronic liver disease in Italy: A multicenter prevalence study of 9,997 cases

Knowledge of the current epidemiology of chronic liver disease in Italy is mostly obsolete and fragmentary for the lack of up-to-date consistent data. In 2001, a 6-month prevalence study was undertaken in 79 hospitals to assess the characteristics of chronic liver disease in Italy. Both prevalent and incident cases were enrolled. A total of 9,997 patients were recruited, of whom 939 (9.4%) had normal liver biochemistry, 6,210 (62.1%) had chronic hepatitis, 1,940 (19.4%) had liver cirrhosis, and 341 (3.4%) had hepatocellular carcinoma (HCC). In 567 patients (5.7%) the diagnosis was not established. Hepatitis C virus (HCV) was found in 69.9% of the patients and was the only etiological factor in 56.3% of all the patients. Hepatitis B surface antigen (HBsAg) was present in the serum of 13.4% of the cases (in 10% it was the only etiological factor). A history of alcohol abuse was found in 23% of the cases (9.4% without viral infection). The prevalence of HCV-related cases was significantly lower in incident than in prevalent cases (44.9% vs. 59.9%, P < 0.0001), while the proportion of patients with alcohol abuse was much higher in incident than in prevalent cases (18.1% vs. 6.6%, P < 0.0001). These findings indicate that nearly one quarter of patients with chronic liver diseases in Italy have a severe disease such as liver cirrhosis and HCC represents a not negligible burden for the national health system. Hepatitis B fell in importance as an etiological factor. Hepatitis C is the important pathogenic factor for chronic liver disease in Italy. However, a comparison between the prevalent and incident cases suggests that in future HCV infection will also play a progressively decreasing role, in part as a consequence of treatment. © 2005 Wiley-Liss, Inc
