Abstract:
This study investigated the antimicrobial resistance of isolates from patients with refractory Helicobacter pylori. The resistance rate was 34.1% for amoxicillin, 92.7% for clarithromycin, 65.9% for metronidazole, 85.4% for levofloxacin, and 29.3% for rifabutin. Dual resistance to both clarithromycin and levofloxacin was found in 73.2%. The antimicrobial resistance rate of refractory H. pylori was extremely high, which had become a major consideration in therapeutic challenge.

Gastritis III: Clinical Manifestations and Management
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
