BACKGROUND AND AIMS: The association between inflammatory bowel disease [IBD] and cancer remains poorly defined in Asian populations. Therefore, we conducted a nationwide population-based study to determine the cancer risk in Korean patients with IBD. METHODS: Using the National Health Insurance claims data, we collected data on patients diagnosed with IBD (5595 Crohn's disease [CD] and 10 049 ulcerative colitis [UC]) from 2011 to 2014. Standardized incidence ratios [SIRs] of overall and site-sp

OBJECTIVES: The work of public officers involves repeated and long-term exposure to heavy workloads, high job strain and workplace violence, all of which negatively impact physical and mental health. This study aimed to evaluate and compare the incidences of diseases among different categories of public officers in Korea, in order to further understand the health risks associated with these occupations. DESIGN: A cohort study using the National Health Insurance data. PARTICIPANTS: We collated cl

OBJECTIVE: Rheumatoid arthritis (RA) is a chronic autoimmune disease that is often painful and debilitating. Patients with RA are increasingly receiving complementary and alternative medicine (CAM). We aimed to identify the patient characteristics and disease-specific factors associated with Korean patients with RA who decide to start treatment with CAM. METHODS: Among the total 5371 patients with RA in the KORean Observational study Network for Arthritis (KORONA), 2175 patients who had no exper

Patients receiving early anti-TNF therapy had similar clinical outcomes to those of late initiators, suggesting that early anti-TNF therapy initiation offers little benefit in patients with UC.

BACKGROUND AND AIM: Variation in medical care can be an obstacle to improving quality and outcome of treatment. We conducted a nationwide, population-based study to identify regional variations in medication prescription rates in Korean patients with inflammatory bowel diseases (IBDs). METHODS: Using the National Health Insurance claims, we collected data on patients diagnosed with IBD (8974 cases of Crohn's disease [CD] and 17 167 cases of ulcerative colitis [UC]) between 2010 and 2016. RESULTS

PURPOSE: Data on the comparative effectiveness of infliximab (IFX) or adalimumab (ADA) in patients with ulcerative colitis (UC) are extremely limited, especially in the Asian population. We compared clinically important outcomes [colectomy, UC-related emergency room (ER) visits, UC-related hospitalizations, and need for corticosteroids] for these two biologics in biologic-naïve Korean patients with UC. MATERIALS AND METHODS: Using National Health Insurance claims, we collected data on patients w

Patients with intestinal BD demonstrated a higher risk of hematologic cancer, especially leukemia, than the general population. Furthermore, women with intestinal BD showed a higher risk of all cancers.

The increased overall risk of developing IA after tuberculosis corroborates the hypothesis that tuberculosis can trigger dysregulated immunity. This necessitates an increased awareness of autoimmunity in this patient group.
