Abstract PDF Supplementary Material PubReader ePub: Background/Aims
Patients with ulcerative colitis (UC) in remission commonly restrict thir lifestyle to prevent relapse; however, the effectiveness and impact on quality of life (QOL) is unclear. This study investigated whether lifestyle restrictions are associated with relapse reduction and assessed their impact on QOL.
Methods
This multicenter, prospective cohort study was conducted in Japan (2018–2021) via the YOURS registry, enrolling patients with UC in clinical remission. Patients were followed for 2 years. A baseline questionnaire evaluated lifestyle restrictions in diet, work/study/housework, and physical exercise. QOL was assessed by Disease Impact Scale every 3 months during the first year of follow-up. Associations of lifestyle restrictions with relapse and QOL were assessed by Cox regression analysis and linear mixed-effects models, respectively.
Results
Among 911 patients in clinical remission for > 90 days, 63% had adopted dietary avoidance; 47%, work/study/housework avoidance; and 8%, physical exercise avoidance. Overall, 216 patients relapsed. Lifestyle restrictions were not associated with reduced risk of relapse (multivariableadjusted hazard ratios [95% confidence interval]: dietary avoidance, 1.08 [0.81–1.44]; and work/study/housework avoidance, 1.14 [0.87–1.50]); physical exercise avoidance was associated with increased relapse (multivariable-adjusted hazard ratio, 1.58; 95% confidence interval, 1.02–2.44). All lifestyle restrictions were associated with impaired QOL (P <0.01).
Conclusions
Lifestyle restrictions were not associated with relapse reduction in patients with UC; however, they were associated with impaired QOL. Clinicians should engage in evidence-based discussions with patients with UC in remission regarding lifestyle restrictions (UMIN Clinical Trials Registry; UMIN000031995).

Efficacy of serum leucine-rich alpha-2 glycoprotein in predicting findings of Crohn’s disease small bowel lesion in capsule endoscopy: Teppei Omori, Miki Koroku, Shun Murasugi, Ayumi Ito, Maria Yonezawa, Shinichi Nakamura, Katsutoshi Tokushige; Intest Res 2024;22(4):464-472.

Background/Aims
Small bowel capsule endoscopy (SBCE) is an evaluation method for small bowel (SB) lesions in Crohn’s disease (CD). However, the relationship between SBCE findings and the serological biomarker leucine-rich alpha-2 glycoprotein (LRG) remains unclear. We aimed to establish appropriate cutoff values of LRG to predict the presence of SB lesions in CD through SBCE.
Methods
Patients with CD with SB lesions who had undergone SBCE and LRG measurements 1 month before and after the SBCE were included. The LRG values for ulcers ≥0.5 cm and other inflammatory lesions noted in SBCE were determined using the Youden Index, and the sensitivity and specificity were calculated. Additionally, the correlation between the SBCE scores (CD Activity in Capsule Endoscopy) and LRG values was evaluated.
Results
Forty patients without active colorectal lesions were included in the study. When the cutoff value of LRG for SB ulcers ≥ 0.5 cm was set at 14 μg/mL, the sensitivity was 92.3%, specificity was 81.5%, positive predictive value (PPV) was 70.6%, and negative predictive value (NPV) was 95.7%. In contrast, an LRG cutoff value of 12 μg/mL without inflammatory findings had a sensitivity of 91.7%, specificity of 82.1%, PPV of 68.8%, and NPV of 95.8%. CD Activity in Capsule Endoscopy correlated well with LRG values (Spearman’s rank correlation coefficient ρ = 0.681, P< 0.001).
Conclusions
An LRG cutoff value of 14 μg/mL may be useful in predicting the presence of SB ulcers ≥ 0.5 cm, and an LRG cutoff value of 12 μg/mL may be useful in predicting the absence of SB inflammatory findings.

Abstract PDF PubReader ePub

Coronavirus disease 2019 (COVID-19), caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is now a pandemic. Although several treatment guidelines have been proposed for patients who have both inflammatory bowel disease and COVID-19, immunosuppressive therapy is essentially not recommended, and the treatment options are limited. Even in the COVID-19 pandemic, adjuvant adsorptive granulocyte and monocyte apheresis may safely bring ulcerative colitis (UC) into remission by removing activated myeloid cells without the use of immunosuppressive therapy. Our patient was a 25-year-old Japanese male with UC and COVID-19. This is the first case report of the induction of UC remission with granulocyte and monocyte apheresis treatment for active UC associated with COVID-19.
