Aplastic anemia associated with Crohn ’s disease: a tertiary center retrospective study

AbstractAplastic anemia (AA) has been reported to be associated with inflammatory bowel disease (IBD), but mostly with ulcerative colitis (UC). Little is known about the associations between AA and Crohn ’s disease (CD). We aim to determine the portraits of patients with AA-CD. Among a total of 657 patients with CD registered in Xijing Hospital of Digestive Diseases IBD center from January 2008 to October 2018, the patients diagnosed with concurrent AA were reviewed. Clinical presentation, medical history, endoscopic features, response to treatment, and prognosis in this set of patients were collected. Six male patients confirmed as CD associated with AA were identified. The incidence rate was 0.91% for CD associated with AA in our series. Average age at diagnosis of CD and AA was 41.5 and 3 9.2 years old, respectively. Abdominal pain and hyperpyrexia were the most common symptoms. Endoscopic findings showed discontinued severe inflammation, and all these patients presented with deformed ileocecal valve. Conventional pharmacotherapy failed to achieve a favorable effect. Four of six pat ients died from CD progression and its complications. None of these patients received bone marrow transplantation treatment because of poverty. Concurrence of AA and CD is a relatively rare condition. Immunologic impairment may play an important pathogenic role and deserves further attention. Males are more susceptible to this condition. Patients with AA-CD are prone to a severe clinical cou...
