Allergic diseases and ulcerative colitis (UC) share pathophysiological similarities. This study aimed to investigate the unclear association between allergic diseases and mucosal healing (MH), an important factor in the prognosis of UC. We studied 289 Japanese patients with UC.

Article Synopsis
  • Nocturia, or frequent nighttime urination, is a common symptom in patients with lower urinary tract syndrome (LUTS), and its link to ulcerative colitis (UC) has not been widely studied.
  • A study was conducted with 287 Japanese UC patients, who were categorized based on their nighttime urination frequency and evaluated for mucosal healing (MH) and clinical remission (CR) using survey data.
  • Results indicated that higher frequencies of nighttime urination are associated with lower rates of mucosal healing, particularly in younger patients and those in clinical remission, suggesting that nocturia could be a potential indicator of disease status in UC patients.

Socioeconomic status is a risk factor for poor disease prognosis. No studies of patients with ulcerative colitis (UC) have investigated the association between socioeconomic status and erectile dysfunction (ED), although UC is independently positively associated with ED. Therefore, the purpose of this survey to evaluate this issue in Japanese patients with UC.

Double-stranded RNA-activated protein kinase R (PKR) is highly expressed in colorectal cancer (CRC). However, the role of PKR in CRC remains unclear. The aim of this study was to clarify whether C16 (a PKR inhibitor) exhibits antitumor effects and to identify its target pathway in CRC.

The association between ulcerative colitis (UC) and erectile dysfunction (ED) has been previously reported. Numerous previous studies have also reported an association between gastrointestinal symptoms and ED. Constipation and diarrhea are common in patients with UC.

Age is a risk factor for constipation. Constipation is common in patients with ulcerative colitis (UC) and has been positively associated with disease activity, but evidence is limited. This study aimed to assess the association between disease activity and constipation in patients with UC.

Objective: Recently, a close association between ulcerative colitis (UC) and erectile dysfunction (ED) was reported. An inverse relationship between serum albumin and ED is found in patients with chronic disease. However, the association between serum albumin levels and ED in patients with UC is unclear.

Hepatitis B vaccine induces the production of antibodies against hepatitis B surface antigen (anti-HBs) and prevents hepatitis B virus (HBV) infection. However, 5-10% of individuals cannot develop anti-HBs even after multiple vaccinations (HB vaccine non-responders). We developed an intranasal vaccine containing both HBs antigen (HBsAg) and HB core antigen (HBcAg) and mixed it with a viscosity enhancer, carboxyl vinyl polymer (CVP-NASVAC).

Objective: To investigate the association between nocturia and constipation in patients with ulcerative colitis (UC). Constipation has recently been recognized as an important symptom in patients with UC. Although nocturia has been associated with constipation in the general population, the association between nocturia and constipation in UC patients is uncertain.

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.

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).

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.

Article Synopsis
  • A study evaluated the link between the C-reactive protein (CRP)-albumin ratio (CAR) and clinical outcomes in 273 Japanese patients with ulcerative colitis (UC), focusing on remission and mucosal healing.
  • Results showed that high CAR is significantly associated with moderate to severe endoscopic activity, particularly in patients who have had UC for more than 7 years.
  • However, CAR did not show a connection with clinical remission or mucosal healing overall, suggesting it may be a useful marker for disease activity in long-term UC patients.

Background: Epidemiological evidence on the association between physical activity (PA) and ulcerative colitis (UC) is limited, and the effect of PA on the prognosis of UC is currently unknown. We evaluated the association between PA and clinical outcomes, including clinical remission and mucosal healing (MH), in Japanese patients with UC.

Methods: The study subjects were 327 Japanese patients with UC.

Introduction: Monocytes play an important role in innate immunity. Some epidemiological evidence indicates an association between peripheral blood monocytes and ulcerative colitis (UC). The association between peripheral blood monocytes and mucosal healing (MH), however, remains unclear.

Objective: Serum albumin is used as a marker of acute inflammation. Several studies have addressed the association between serum albumin and clinical outcome in patients with ulcerative colitis (UC). While mucosal healing (MH) has been indicated as the therapeutic goal for UC, the association between serum albumin and MH remains unclear.

Background: Although the association between eating habits which can be modified and digestive diseases has been reported, to date, no research has evaluated the association between eating habits and ulcerative colitis (UC). Thus, we investigate the association between eating behavior and clinical outcome in Japanese patients with UC.

Methods: Eating quickly, eating until full, and skipping breakfast data was obtained from a self-administered questionnaire.

Background: Serum globulin is an inflammation marker. To date, no evidence regarding the association between serum globulin and disease activity in patients with ulcerative colitis has been reported.

Aims: We evaluated the association between serum globulin and endoscopic activity in patients with ulcerative colitis.

Background: Mucosal healing (MH) has been indicated as the therapeutic goal for ulcerative colitis (UC). Platelet count is known as an inflammation evaluation. However, the association between platelet count and MH among patients with UC is still scarce.

Purpose: Bilirubin is known to have antioxidant effects. Several pieces of evidence regarding association between serum bilirubin and UC exist. Three studies found that serum bilirubin was inversely associated with severity of ulcerative colitis (UC), but no evidence regarding an association between serum bilirubin and mucosal healing (MH) has yet been shown.
