Improvement of Work Productivity and Quality of Life with Anti-Tumor Necrosis Factor Treatment Used in Crohn's Disease in Routine Clinical Practice in Turkey.

Background: Patients with Crohn's disease experience major deterioration in work productivity and quality of life. We aimed to provide the long-term effects of anti-tumor necrosis factor agents on work productivity and activity impairment and quality of life in patients with Crohn's disease using the Inflammatory Bowel Disease Questionnaire and the Short-Form Health Survey-36. Methods: Patients with Crohn's disease and initiated an anti-tumor necrosis factor treatment were included and followed up for 12 months in this observational study. Results: A total of 106 patients were included in this study, and 64.2% of the patients were males. Mean [+/- standard deviation] age was 36.8 [+/- 10.9] years. At baseline, mostly perianal fistulas [65.7%] were observed [n = 23]. Intestinal stenosis was detected in 34.9% of the patients [n = 37], and most of the stenosis was located in the ileum [70.6%] followed by the colon [20.6%]. Extraintestinal symptoms were observed in 24 patients [22.6%]. Most frequent extraintestinal symptom was arthritis with 71.4% [n = 15]. Mean time from first symptom to initiation of anti-tumor necrosis factor treatment was 6.3 [+/- 5.0] years. Improvements in work productivity and activity impairment scores throughout 12 months were -24.1% [P =.003] for work time missed, -18.0% [P =.006] for impairment at work, -8.5% [P =.160] for overall work impairment, and -17.0% [P <.001] for daily activity impairment. Similarly, significant improvements [P <.001] were detected in all components of the Inflammatory Bowel Disease Questionnaire when compared to baseline. Statistically significant improvements [P <.05] were detected for all components of Short-Form Health Survey-36 except for mental health [P =.095]. Conclusion: Our study indicates the significant improvement in work productivity and activity impairment and quality of life of patients with Crohn's disease who receive long-term anti-tumor necrosis factor treatment.
