Treatment with direct-acting antivirals improves the clinical outcome in patients with HCV-related decompensated cirrhosis: results from an Italian real-life cohort (Liver Network Activity-LINA cohort).

BACKGROUND: Direct-acting antivirals (DAAs) are safe and effective for the treatment of HCV infection. However, data regarding their efficacy in patients with Child-Pugh B cirrhosis are scarce and their capability in improving liver function is debated. The aim of our study was to assess the clinical benefits of treatment with DAA in subjects with Child-Pugh B cirrhosis. METHODS: We conducted a prospective multicentre study among patients with Child-Pugh B cirrhosis of an Italian real-life HCV cohort (LINA cohort) who received treatment with DAAs. RESULTS: Among 89 patients enrolled, the rate of sustained virologic response 12 was 95.5%. No discontinuation occurred, no patient died during treatment. Most patients had Genotype 1 (1b 61.8%, 1a 11.2%). Conversely, 22.5%, 1.1% and 3.4% of patients had Genotype 2, 3 and 4, respectively. At last observation, 61.8% of patients switched to a Class A cirrhosis, 33.7% remained in Class B and 4.5 worsened to Child C (p < 0.001). Liver parameters significantly improved from baseline to 12 weeks after the end of treatment. Previous anti-HCV treatments and the presence of decompensated cirrhosis at 1 month of treatment were significantly associated with a decompensated cirrhosis at the last observation. CONCLUSIONS: Treatment with DAA in patients with Child-Pugh B cirrhosis is safe and leads to a very high rate of viral clearance, a significant rate of re-compensation and an improvement in liver function. Further studies are needed to assess the impact of treatment on survival and quality of life in long-term follow-up.

Pretreatment antimicrobial susceptibility testing is cost saving in the eradication of Helicobacter pylori.

BACKGROUND & AIMS: The major obstacle to 100% effective eradication of Helicobacter pylori infection is represented by antimicrobial-resistant H. pylori strains. This randomized study was designed to evaluate whether regimens based on pretreatment susceptibility testing were more effective and cost saving compared with standard nonsusceptibility testing-based therapy in the eradication of H. pylori infection. METHODS: We studied 150 consecutive H. pylori-infected dyspeptic subjects. Patients were randomly assigned to omeprazole 20 mg twice daily, clarithromycin 500 mg twice daily, and metronidazole 500 mg twice daily for 7 days or to omeprazole 20 mg twice daily and 2 antimicrobials chosen based on susceptibility testing. H. pylori status was reevaluated 12 weeks after the end of treatment by the (13)C-urea breath test. RESULTS: Susceptibility testing-based regimens led to the following results. (1) Eradication rates were 97.3% (95% confidence interval [CI], 91.2%-99.5%) (71 of 73) and 94.6% (95% CI, 87.6%-98.3%) (71 of 75) in the per-protocol and intention-to-treat analysis, respectively. These were significantly higher (P < 0.005) than eradication rates obtained without susceptibility testing, that is, 79.4% (95% CI, 69.1%-87.6%) (58 of 73) and 77.3% (95% CI, 66.9%-85.7%) (58 of 75) in the per-protocol and intention-to-treat analyses, respectively. (2) There were savings of approximately $5 U.S. per patient compared with standard triple therapy. CONCLUSIONS: Pretreatment antimicrobial susceptibility testing is more effective and cost saving and, in health systems that confirm cost advantage, microbial susceptibility testing should be routinely used for eradication of H. pylori infection.
