Case Report: Rare comorbidity of celiac disease and Evans syndrome

Abstract

Background: Celiac disease is an immune-mediated enteropathy due to permanent sensitivity to gluten in genetically predisposed individuals. Evans syndrome is an autoimmune disorder designated with simultaneous or successive development of autoimmune hemolytic anemia and immune thrombocytopenia and/or immune neutropenia in the absence of any cause. Case Report: We report a rare case of Celiac disease and Evans syndrome in a 20-year-old female who presented to us with generalized weakness and shortness of breath. Her examination finding included anemia, jaundice, and raised jugular venous pulse. Her abdominal exam revealed hepatosplenomegaly. Her laboratory values showed microcytic anemia, leukocytosis and thrombocytopenia. To rule out secondary causes of idiopathic thrombocytopenia purpura, we tested viral markers for Human immunodeficiency virus, Epstein bar virus, Cytomegalovirus and performed a Helicobacter pylori test, all of which were negative. We also ruled out idiopathic thrombocytopenia purpura associated with any thyroid disorder.  For celiac disease, we took anti-tissue transgulataminase titers of IgA and IgG which confirmed the diagnosis of celiac disease. For the diagnosis of Evans syndrome, despite a negative serum coombs test initially, her bone marrow sample showed a positive Coombs test along with immune mediated hemolytic anemia and immune mediated thrombocytopenia. The patient was treated with prednisone which was tapered off and counseling was provided regarding a gluten free diet. Conclusion: Although rare, tests for Evans syndrome (and other coexisting autoimmune problems) should be performed in patients with celiac disease.
