The Association Between Helicobacter Pylori Infection and Liver and Biliary Tract Disorders

Area of Science:

• Gastroenterology
• Hepatology
• Microbiology

Background:

• Helicobacter Pylori (HP) infects approximately 50% of the global population, serving as a primary risk factor for peptic ulcers, gastric adenocarcinoma, and MALT gastric lymphoma.
• HP eradication has significantly improved peptic ulcer disease management, offering permanent healing in many instances and representing a key strategy for primary prevention of gastric malignancy.
• Conversely, HP presence offers protective effects against conditions like gastroesophageal reflux disease and associated complications, asthma, and esophageal adenocarcinoma, where eradication may have adverse outcomes.

Purpose of the Study:

• To highlight the significant association between Helicobacter Pylori infection and a spectrum of hepatobiliary disorders.
• To explore the etiological role of HP in conditions such as biliary lithiasis.
• To review the impact of HP infection on cholestatic syndromes, viral hepatitis, and their progression to cirrhosis and hepatocellular carcinoma.

Main Methods:

• Review of existing literature on Helicobacter Pylori infection and its association with gastrointestinal and extragastric pathologies.
• Analysis of studies investigating the role of HP in hepatobiliary disorders, including biliary lithiasis, cholestatic syndromes, and viral hepatitis.
• Examination of the implications of HP eradication on both gastric and extragastric conditions.

Main Results:

• HP infection is linked to immune thrombocytopenic purpura, with improvement observed post-treatment.
• Controversial associations exist between HP infection and ischemic heart disease and cerebrovascular disease.
• A notable association is identified between HP infection and hepatobiliary disorders, including biliary lithiasis, cholestatic syndromes (primary sclerosing cholangitis, primary biliary cholangitis), chronic hepatitis B and C, potentially progressing to cirrhosis and hepatocellular carcinoma.

Conclusions:

• Helicobacter Pylori infection presents a complex dual role, contributing to significant gastric pathologies while also influencing extragastric conditions.
• The association between HP infection and hepatobiliary disorders is increasingly recognized, suggesting a potential etiological or contributing role in conditions ranging from gallstones to liver cancer.
• Further research is warranted to elucidate the mechanisms underlying HP's influence on diverse pathologies and to optimize treatment strategies considering both benefits and risks of eradication.
