Severe Coagulopathy and Intra-Alveolar Haemorrhage Due to Fat Malabsorption in Celiac Disease.

UNLABELLED

Celiac disease, a prevalent autoimmune disorder, can present atypically with fat malabsorption and coagulopathy due to vitamin K malabsorption. A 64-year-old male presented with haemoptysis and severe anaemia (Hb 6 g/dl). Despite normal previous coagulation tests, admission laboratory tests revealed an international normalised ratio (INR) of 7.0 and iron deficiency anaemia. Initial blood products and vitamin K treatment corrected the INR temporarily, but the patient's haemoptysis returned, and his INR values continued to rise. Further investigation revealed celiac disease with fat malabsorption, leading to vitamin K malabsorption and along with a previously prescribed antiplatelet aggregation therapy, this led to diffuse alveolar haemorrhage. A gluten-free diet and vitamin supplementation normalised the patient's INR and stopped the bleeding. This case highlights the importance of considering celiac disease in unexplained coagulopathies and the effectiveness of dietary management.

LEARNING POINTS

Celiac disease can cause severe coagulopathy due to fat malabsorption and vitamin K deficiency.High suspicion is required for atypical presentations of celiac disease.A gluten-free diet is essential for managing celiac disease and normalising coagulation profiles.
