Delayed endoscopy as a risk factor for in-hospital mortality in cirrhotic patients with acute variceal hemorrhage.
Risk factors for mortality in acute variceal hemorrhage remain incompletely understood. Whether endoscopy timing is associated with risk of mortality has not been investigated. We aimed to investigate risk factors for in-hospital mortality in cirrhotic patients with acute variceal hemorrhage, with emphasis on endoscopy timing. ⋯ Delayed endoscopy for more than 15 h, high MELD score, failure of the first endoscopy and hematemesis are independent risk factors for in-hospital mortality in cirrhotic patients with acute variceal hemorrhage.

Resistance to metronidazole, clarithromycin and levofloxacin of Helicobacter pylori before and after clarithromycin-based therapy in Taiwan.
Clarithromycin-based triple therapy has been commonly applied as the first-line therapy for Helicobacter pylori eradication. Levofloxacin could serve as an alternative in either first-line or second-line regimens. This study surveyed the prevalence of levofloxacin resistance of H. pylori isolates in naive patients and in patients with a failed clarithromycin-based triple therapy. ⋯ The levofloxacin resistance of naive H. pylori remains less than 10% in Taiwan. With relatively lower resistance to levofloxacin than to metronidazole of the H. pylori isolates collected after a failed clarithromycin-based therapy, proton pump inhibitor-levofloxacin-amoxicillin may be an alternative choice to serve as the second-line therapy.
