[Biermer's disease and autoimmune hemolytic anemia]

Area of Science:

• Gastroenterology
• Immunology
• Hematology

Background:

• Biermer's disease is an autoimmune atrophic gastritis impacting vitamin B12 absorption.
• Autoimmune disorders frequently co-occur with Biermer's disease.
• Autoimmune hemolytic anemia (AIHA) is a less commonly reported co-occurrence.

Observation:

• A 66-year-old patient presented with Biermer's disease.
• The patient also exhibited symptoms and diagnosis of AIHA.

Findings:

• This case documents a rare co-occurrence of Biermer's disease and AIHA.
• The findings underscore the complex interplay between autoimmune conditions.

Implications:

• Recognizing this association is crucial for comprehensive patient diagnosis and management.
• Further research may elucidate shared autoimmune pathways or triggers.
• This case emphasizes the need for vigilance in patients with Biermer's disease for other autoimmune conditions like AIHA.
