Entecavir and tenofovir achieved high biochemical and virological response. Renal function remained stable with both drugs. A Page-B cut-off ≥10 selected all patients at risk of HCC development.

SUMMARY AimTo study the incidence of Helicobacter pylori recurrence, its chronological aspects, and the variables that might influence it. MethodsA total of 1000 patients in whom H. pylori had been eradicated were prospectively studied. Therapies were classified as low and high efficacy regimens. Four to eight weeks after completion of therapy, 13 C-ureabreath-test was performed, and it was repeated yearly up to 5 years. In some patients, endoscopy with biopsies was also performed to confirm H. pylori eradication. ResultsA total of 1000 patients were included, giving 2744 patient-years of follow-up. Seventy-one H. pylori recurrences were observed (2.6% per patient-year). Probability of being H. pylori-negative at 1 year was 94.7%, and at 5 years 90.7%. In the multivariate analysis, low age (OR: 1.84; 95% CI: 1.04-3.26) and low efficacy therapies (OR: 2.5; 1.23-5.04) correlated with 1-year H. pylori recurrence. Differences were observed when Kaplan-Meier curves were compared depending on age and therapy regimen. ConclusionRisk of posteradication H. pylori recurrence is higher during the first year, which suggests that most recurrences during this period are recrudescence and not true reinfections. H. pylori recurrence is more frequent in younger patients and in those treated with low efficacy therapies, but is exceptional if high efficacy therapies are used, in which case posttherapy eradication can be safely confirmed at 4 weeks with 13 C-ureabreath-test.

Ten-day levofloxacin-based rescue therapy constitutes an encouraging second-line strategy, representing an alternative to quadruple therapy in patients with previous proton pump inhibitor-clarithromycin-amoxicillin failure, being simple and safe.

We investigated whether autoimmune cholangitis (AC) has specific features that constitute an entity other than primary biliary cirrhosis (PBC). We compared clinical, laboratory, and liver biopsy features; response to treatment; and the follow-up of two groups of patients. The first group comprised seven patients with AC criteria-PBC with negative antimitochondrial antibodies (AMAs) and positive antinuclear antibodies (ANAs)-termed the PBC AMA-negative group; the second was made up of another seven PBC patients with positive AMA, labeled the PBC AMA-positive group. We found that the PBC AMA-negative group had, besides negative AMAs and positive ANAs, a significantly higher incidence of asthenia, a higher and earlier incidence of liver failure, and higher ANA titers and serum immunoglobulin G levels than the PBC AMA-positive group. There were no significant differences in the other laboratory tests, although the PBC AMA-negative group showed higher serum bilirubin and aminotransferase and lower serum alkaline phosphatase and immunoglobulin M levels. Liver histological data were similar in both groups. Patients in the PBC AMA-negative group, with more markedly abnormal liver tests, responded to immunosuppressive therapy. We concluded that patients with criteria for PBC but with negative AMAs and positive ANAs have a few specific features that fall between PBC and autoimmune chronic hepatitis. This finding suggests that these patients have a different disease, for which autoimmune cholangitis seems to be an appropriate name.
