title: Celiac disease with diffuse cutaneous vitamin K-deficiency bleeding.
abstract: This article describes a 4-y-old girl with spontaneous, generalized bruising, abdominal distention, and signs of malnutrition. She had been treated previously with an antibiotic for diarrhea. Laboratory analyses showed the presence of iron-deficiency anemia, mild hypoalbuminemia, and considerably prolonged prothrombin time and activated thromboplastin time. Tests revealed that hemostasis improved after the patient received fresh frozen plasma. A coagulation profile showed a decrease in clotting factors II, VII, IX, and X. The patient was given intravenous vitamin K therapy (5 mg/d) for 3 d. All coagulation tests were normalized, and bruising started to disappear. Positive serology (immunoglobulin A antitissue transglutaminase and immunoglobulin A antiendomysial antibodies) and smallbowel mucosal histopathology confirmed the presence of celiac disease (CD). The girl recovered completely after she was put on a gluten-free diet. Vitamin K-deficiency bleeding is a rare complication that occurs almost exclusively in patients with typical CD manifestations. In addition to antibiotic therapy, treatment with other drugs that influence vitamin K resorption and metabolism may increase the risk of bleeding in patients with CD with hypoprothrombinemia.
