Pseudopolycythaemia and coeliac disease

Area of Science:

• Gastroenterology and Hematology
• Dietary Interventions and Clinical Outcomes

Background:

• Coeliac disease is an autoimmune disorder triggered by gluten ingestion.
• A strict gluten-free diet is the primary treatment for coeliac disease.
• Potential side effects of dietary changes require ongoing investigation.

Observation:

• Two patients with coeliac disease were observed.
• These patients initiated a gluten-free diet as part of their treatment.
• Pseudopolycythaemia developed in both patients following the dietary change.

Findings:

• A correlation was identified between the introduction of a gluten-free diet and the onset of pseudopolycythaemia.
• This association was observed in two distinct cases.
• The mechanism linking gluten-free diet to pseudopolycythaemia remains to be elucidated.

Implications:

• The findings suggest a potential, previously unrecognized adverse effect of gluten-free diets.
• Further research is warranted to confirm this association and explore underlying mechanisms.
• Clinicians should be aware of this potential complication when managing coeliac disease patients.
