Liver abnormalities in celiac disease.

Area of Science:

• Gastroenterology and Hepatology
• Autoimmune Disorders

Background:

• Celiac disease is a small intestinal autoimmune disorder triggered by gluten.
• While gastrointestinal symptoms are common, extra-intestinal manifestations, including liver disease, are frequently observed.
• Hepatobiliary conditions associated with celiac disease range from elevated liver enzymes to autoimmune hepatitis and nonalcoholic fatty liver disease.

Purpose of the Study:

• To review the literature on hepatic abnormalities associated with celiac disease.
• To highlight the importance of considering celiac disease in patients with unexplained liver enzyme elevations.
• To propose an investigative and management strategy for these patients.

Main Methods:

• Literature review of studies investigating the relationship between celiac disease and liver abnormalities.
• Analysis of case reports and clinical series describing hepatobiliary manifestations in celiac patients.
• Synthesis of findings to outline diagnostic and therapeutic approaches.

Main Results:

• Celiac disease is linked to a spectrum of liver conditions, including elevated liver enzymes, nonspecific hepatitis, NAFLD, and autoimmune liver diseases.
• In many cases, celiac disease is the primary cause of unexplained liver enzyme abnormalities.
• Liver enzyme levels typically normalize upon adherence to a gluten-free diet.

Conclusions:

• A high index of suspicion is crucial for diagnosing celiac disease, especially in patients with liver abnormalities and minimal GI symptoms.
• Screening for celiac disease should be considered in individuals with unexplained liver enzyme elevations.
• Implementing a gluten-free diet is an effective treatment for normalizing liver function in celiac disease patients with hepatic manifestations.
