A Case of Polyautoimmunity: Celiac Hepatitis, Grave's Disease and Autoimmune Hemolytic Anemia

Area of Science:

• Immunology
• Hepatology
• Endocrinology

Background:

• Celiac disease (CD) is an autoimmune disorder often associated with gastrointestinal issues and malignancy risk.
• Polyautoimmunity, the presence of multiple autoimmune conditions in one patient, necessitates thorough investigation and management.
• Grave's disease (GD) and CD are known autoimmune comorbidities.

Observation:

• A rare case involving a patient with previously diagnosed CD and GD presented with newly diagnosed autoimmune hemolytic anemia (AIHA) and cirrhosis.
• The patient's condition, including celiac hepatitis, was diagnosed after extensive work-up, ruling out other autoimmune liver diseases.
• Complications such as ascites were managed alongside treatment for the coexisting autoimmune conditions.

Findings:

• Non-adherence to a strict gluten-free diet (GFD) was identified as a critical factor leading to severe adverse events in this patient with polyautoimmunity.
• The patient required a multi-faceted treatment approach, including GFD, carbimazole for GD, and medications for cirrhosis with ascites.
• This case underscores the potential severity of CD complications when dietary adherence is compromised.

Implications:

• This case emphasizes the critical importance of strict gluten-free diet adherence in managing celiac disease to prevent severe multi-organ complications.
• It highlights the complexity of managing polyautoimmunity, where multiple autoimmune conditions interact and require tailored therapeutic strategies.
• Further research into the intricate relationship between CD, its complications, and other autoimmune disorders like GD and AIHA is warranted.
