Migraine is associated with the development of adult patients with inflammatory bowel disease: a nationwide, population-based study.

It has been reported that migraine is more common in patients with inflammatory bowel disease (IBD) than in general. However, the impact of migraine on the development of IBD has not yet been elucidated. The aim of this study was to determine the association between migraine and the development of IBD.

Impact of Crohn's Disease on the Survival of Patients with Small-Bowel Adenocarcinoma in Korea: A Bicenter Cohort Study.

Background/aims: Owing to the low prevalence of small-bowel adenocarcinoma (SBA), data on the impact of Crohn's disease (CD) on the survival of patients with SBA are lacking. Therefore, we investigated this issue in this study.

Methods: In this bicenter cohort study, patients with histologically confirmed SBA were retrospectively enrolled and classified into two groups: sporadic SBA and CD-associated SBA.

Depression in patients with inflammatory bowel disease is associated with increased risk of dementia and Parkinson's disease: A nationwide, population-based study.

Background: Inflammatory bowel disease (IBD) may be associated with depression which is considered an important cause of dementia and Parkinson's disease (PD). In the present study, the effects of depression on the development of dementia and/or PD in patients with IBD were evaluated.

Materials And Methods: A nationwide population-based cohort study was conducted using claims data from the Health Insurance Review and Assessment Service in Korea.

Increased risk of idiopathic pulmonary fibrosis in inflammatory bowel disease: A nationwide study.

Background And Aim: The relationship between inflammatory bowel disease (IBD) and idiopathic pulmonary fibrosis (IPF) remains unclear. We evaluated the risk for developing IPF in patients with IBD using a nationwide population-based study.

Methods: Using claims data from the National Health Insurance service in Korea, patients with IBD, including Crohn's disease (CD) and ulcerative colitis (UC), were identified through both the 10th revision of the International Statistical Classification of Diseases and Related Health Problems and rare and intractable disease program codes from January 2010 to December 2013.

Risk of Anxiety and Depression in Patients with Inflammatory Bowel Disease: A Nationwide, Population-Based Study.

Background And Aims: Inflammatory bowel disease (IBD) may be associated with anxiety and depression. The aim of this study was to evaluate the incidence of anxiety and depression in patients with IBD compared to the general population. Methods A nationwide population-based cohort study was conducted using claims data from the National Healthcare Insurance service in Korea.

Increased end-stage renal disease risk in patients with inflammatory bowel disease: A nationwide population-based study.

Aim: To estimate the risk of end-stage renal disease (ESRD) in patients with inflammatory bowel disease (IBD).

Methods: From January 2010 to December 2013, patients with Crohn's disease (CD) and ulcerative colitis (UC) were identified, based on both the International Classification of Diseases, 10 revision (ICD-10) and the rare, intractable disease registration program codes from the National Health Insurance (NHI) database in South Korea. We compared 38812 patients with IBD to age- and sex-matched non-IBD controls with a ratio of 1:3.
