Long-term outcomes of patients with primary intestinal follicular lymphoma managed with watch-and-wait strategy.

Patients with primary intestinal follicular lymphoma are often followed-up without a specific treatment, and this approach is called the "watch-and-wait approach." However, the long-term outcomes of this patient group have not been sufficiently investigated. We enrolled patients with primary intestinal follicular lymphoma who were diagnosed before 2016 and managed with the watch-and-wait approach in 20 institutions.

Association between Mucosal Healing and Lipid Profiles in Patients with Ulcerative Colitis: A Cross-Sectional Study.

Introduction: Recent meta-analysis showed that ulcerative colitis (UC) is a risk factor for cardiovascular disease (CVD). Dyslipidemia is a well-established risk factor for CVD. However, evidence regarding inflammatory bowel disease (IBD), including UC and lipid profiles, is limited.

Association between socioeconomic status and mucosal healing in Japanese patients with ulcerative colitis: a cross-sectional study.

Objective: Socioeconomic status is a risk factor for worse outcomes in many diseases. However, evidence on the association between socioeconomic status and clinical outcome in patients with ulcerative colitis (UC) is limited. In the clinical setting, the therapeutic goal for UC is to achieve mucosal healing (MH).

Association between clinical outcomes and restless legs syndrome in Japanese patients with ulcerative colitis.

Restless legs syndrome (RLS) is a common sleep disorder in the Western population. The prevalence of restless legs syndrome in the Japanese population is 4.6%.

IL12B rs6887695 polymorphism and interaction with alcohol intake in the risk of ulcerative colitis in Japan.

Background: The interleukin (IL)-23/Th17 pathway plays a critical role in ulcerative colitis (UC). The IL-12p40 subunit, which is shared by IL-23 and IL-12, is encoded by the IL12B gene. The current case-control study investigated the association between IL12B SNP rs6887695 and the UC risk.

The albumin to globulin ratio is associated with clinical outcome in Japanese patients with ulcerative colitis.

Purpose: The albumin to globulin ratio (AGR) is a recognized chronic inflammation marker. No evidence regarding the relationship between AGR level and ulcerative colitis (UC) exists. The aim of this study was to evaluate the association between AGR and clinical outcomes among Japanese subjects with UC.

Active and passive smoking and risk of ulcerative colitis: A case-control study in Japan.

Background And Aim: Although an inverse relationship between current smoking and the development of ulcerative colitis (UC) has been shown in North America and Europe, evidence is limited in Asian countries, where the incidence of UC is rapidly increasing.
