Introduction: Nocturia is a common symptom of lower urinary tract syndrome (LUTS). In previous studies, a close association between LUTS and colorectal inflammation has been reported. However, evidence regarding the association between nighttime urinary frequency and ulcerative colitis (UC) is limited. Herein, we investigated the association between nighttime urinary frequency and clinical outcomes of UC., Methods: We surveyed 287 Japanese patients with UC. A self-administered questionnaire was used to collect the information on the variables studied. Patients were divided into three groups based on nighttime urinary frequency: (1) no voids, (2) one void, and (3) two or more voids. The assessment of clinical outcomes was based on mucosal healing (MH) and clinical remission (CR). The association between nighttime urinary frequency and prevalence of MH and CR was evaluated using multivariate logistic regression analyses., Results: The prevalence of one nighttime frequency and two or more nighttime frequency in this cohort was 35.5% and 26.8%, respectively. The percentage of MH and CR was 24.7% and 59.2%, respectively. Two or more nighttime frequency (adjusted odds ratio [OR]: 0.31, 95% confidence interval [CI]: 0.13-0.73) was independently and inversely associated with MH. In nonelderly patients (<70 years) and patients in CR, an association between two or more nighttime frequency and MH remained significant (non-elderly: adjusted OR: 0.27, 95% CI: 0.09-0.72 and only CR: adjusted OR: 0.34, 95% CI: 0.12-0.90)., Conclusion: Nighttime urinary frequency was independently and inversely associated with MH in Japanese patients with UC. Nighttime urinary frequency may serve as a complementary physical sign of MH in patients with UC., (© 2024 Wiley Periodicals LLC.)

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. The study enrolled 165 patients with UC. Education status (low, middle, high) and household income (low, middle, high) were classified in three groups using self-administered surveys. The information regarding the Sexual Health Inventory for Men (SHIM) was obtained using self-administered questionnaires. The definition of mild to moderate or severe ED and severe ED was SHIM score <17 and SHIM score <8, respectively. The prevalence of mild to moderate or severe ED and severe ED was 64.9% and 47.9%, respectively. In crude analysis, household income was inversely associated with mild to moderate or severe ED and severe ED. After adjustment for age, current drinking, current smoking, exercise habit, body mass index, mucosal healing, and duration of UC, high household income was independently and inversely associated with mild to moderate or severe ED (adjusted odds ratio [OR] 0.23, 95% confidence interval [CI] [0.05, 0.93], p for trend = .038) and severe ED (adjusted OR 0.26, 95% CI [0.07, 0.85], p for trend = .024). In contrast, no association between education status and ED was found. In conclusion, household income was independently and inversely associated with ED in Japanese UC patients., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

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. This study aims to investigate this issue in Japanese patients with UC., Methods: One hundred and thirty-six Japanese male UC patients were enrolled in this study. Information on serum albumin levels and medications for UC from medical records, Sexual Health Inventory for Men (SHIM) score information from self-administered questionnaires and information on the severity of UC from physician reports were obtained from medical records, self-administered questionnaires, and reports from physicians. The participants were divided into tertiles based on the total protein, serum globulin, serum albumin, aspartate aminotransferase, and C-reactive protein levels. The definition of ED and severe ED was SHIM score < 22 and SHIM score < 8, respectively. The association between these serum markers and ED was assessed by multivariate logistic regression., Results: The prevalence of severe ED in the low, moderate, and high albumin groups was 66.0%, 51.0%, and 28.3%, respectively. After adjusting for confounding factors, the low albumin group was independently and positively associated with severe ED (adjusted odds ratio: 2.74, 95% confidence interval: 1.03-7.48, p for trend =0.044). No association between other marker and ED was found., Conclusion: Serum albumin was independently inversely associated with severe ED in Japanese patients with UC. Hypoalbuminemia might be a useful complementary marker for assessing the prevalence and severity of ED in UC patients., (© 2023 The Japanese Urological Association.)

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., Methods: Consecutive series of 290 Japanese patients with UC, Information on constipation, nocturia, and lifestyle habits was obtained using self-administered questionnaires. The definition of constipation was based on Rome I criteria and/or current medication for constipation. Patients were divided into three groups based on nighttime urination: (1) no nocturia, (2) mild nocturia (nocturnal urination - one), and (3) serious nocturia (nocturnal urination - two or more). Multivariate logistic regression was used to evaluate the association between nocturia and constipation., Results: Among all of the UC patients, the prevalence of mild nocturia, serious nocturia, and constipation was 35.2%, 26.9%, and 12.4%, respectively. The prevalence of constipation in the none, mild, and serious nocturia groups was 8.2%, 10.8%, and 20.5%, respectively. After adjustment for confounders such as age, sex, current drinking, current smoking, body mass index, and steroid use, nocturia severity was independently and positively associated with constipation (adjusted odds ratio for mild nocturia: 1.55 [95% confidence interval: 0.57-4.28], serious nocturia: 3.19 [95% confidence interval: 1.09-9.81], P for trend=.035)., Conclusion: The severity of nocturia is positively associated with constipation, and physicians should consider the interrelationships between nocturia and constipation in managing UC patients., Competing Interests: Declaration of Competing Interest The authors declare that there is no conflict of interest regarding the publication of this article., (Copyright © 2023 Elsevier Inc.

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. Additionally, no study has assessed the association between endoscopic activity and lipid profiles in patients with IBD. Therefore, we aimed to clarify the association between mucosal healing (MH) and lipid profiles in patients with UC., Methods: A total of 221 Japanese patients with UC were enrolled in this analysis. Total cholesterol (T-chol), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C) were divided into tertiles (high, moderate, and low) based on the distributions, respectively. Self-administered questionnaire was used to obtain information regarding medication for dyslipidemia. Complete MH and MH are based on Mayo endoscopic subscore 0 and 0-1, respectively., Results: The percentage of complete MH was 30.8%. In patients without medication for dyslipidemia, high HDL-C (>66 mg/dL) was significantly positively associated with complete MH (adjusted odds ratio [OR] 2.58, 95% CI: 1.04-6.64, p for trend = 0.037). In patients with nonproctitis, a positive association between HDL-C and complete MH was found (adjusted OR 3.54, 95% CI: 1.22-11.01, p for trend = 0.020). T-chol and TG were not associated with MH, regardless of medication for dyslipidemia., Conclusions: Complete MH was significantly positively associated with HDL-C in UC patients without medication for lipid. The disease extent might affect the association between complete MH and HDL-C., (© 2022 S. Karger AG, Basel.)

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%. Inflammatory and/or immune alteration might be associated with the development of restless legs syndrome. Ulcerative colitis is a chronic inflammatory bowel disease. Evidence regarding the association between ulcerative colitis and the prevalence of restless legs syndrome is limited. Herein, we investigated the association between clinical outcomes and the prevalence of restless legs syndrome in Japanese patients with ulcerative colitis. This was a cross-sectional study using baseline data from a prospective cohort study. Subjects in this study were 273 patients with ulcerative colitis. The definition of restless legs syndrome was achieved using a self-administered questionnaire based on the diagnostic criteria for restless legs syndrome in an epidemiological study approved by the Executive Committee of the International Restless Leg Syndrome Study Group in 2002. Clinical outcomes were clinical remission and mucosal healing. The association between clinical remission and mucosal healing and the prevalence of restless legs syndrome was assessed by multivariate logistic regression analyses. The percentage of clinical remission and mucosal healing was 58.4% and 63.1%, respectively. The prevalence of restless legs syndrome in this cohort was 4.7%. Clinical remission (adjusted odds ratio 0.23, 95% confidence interval 0.05-0.93) and mucosal healing (adjusted odds ratio 0.23, 95% confidence interval 0.05-0.90) were independently inversely associated with restless legs syndrome. No association between serum haemoglobin and restless legs syndrome was found. In conclusion, clinical remission and mucosal healing were independently and inversely associated with the prevalence of restless legs syndrome in Japanese patients with ulcerative colitis., (© 2022 European Sleep Research Society.)

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). Thus, the aim of this study is to examine the association between socioeconomic status and MH in patients with UC., Methods: The study population consisted of 298 patients with UC. Education status and household income were divided into three groups based on a self-administered questionnaire. MH and complete MH were defined as a Mayo endoscopic subscore of 0-1 and 0, respectively. The association of socioeconomic status with MH and complete MH was assessed by multivariate logistic regression analysis. Patients with UC were divided into a younger group (<51 years old) and an older group (≥51 years old) based on median age., Results: The percentage of MH and complete MH was 62.4% and 25.2%, respectively. In all patients, socioeconomic status was not associated with MH and complete MH, respectively. In the older group, education but not household income was independently positively associated with MH and complete MH. In contrast, in the younger group, no association between socioeconomic status and MH and complete MH was found., Conclusion: In older Japanese patients with UC, education status but not household income was independently positively associated with MH and complete MH., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: A simple serum biomarker for clinical outcome in patients with ulcerative colitis (UC) remains an unmet need. Some studies have shown an association between C-reactive protein (CRP)-albumin ratio (CAR) and prognosis in patients with inflammatory bowel disease (IBD), but evidence regarding the association between CAR and UC remains limited. We evaluated the association between CAR and clinical outcome in Japanese patients with UC., Methods: Subjects were 273 Japanese patients with UC. Clinical remission was defined as absence of both abnormally high stool frequency (< 3 per day) and rectal bleeding. Mucosal healing (MH) was defined as Mayo endoscopic subscore (MES) 0. Moderate to severe endoscopic activity was defined as MES 2-3. Subjects were divided according to CAR into tertiles (low, moderate, and high)., Results: The proportions of patients with clinical remission, MH, and moderate to severe endoscopic activity were 57.9%, 26.0%, and 37.0%, respectively. High CAR was significantly positively associated with moderate to severe endoscopic activity but not MH or clinical remission after adjustment (adjusted odds ratio [OR] 2.18 [95% confidence interval (CI) (1.11-4.35)], p for trend 0.023), but only in patients with long disease duration (> 7 years) (adjusted OR 2.95 [95% CI (1.06-8.79)], p for trend 0.023). CAR was not associated with clinical remission or MH., Conclusions: CAR may be significantly positively associated with moderate to severe endoscopic activity but not clinical remission or MH in Japanese patients with UC. In patients with long UC duration, CAR might be a useful serum marker for disease activity., (© 2022. The Author(s).)

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., Methods: Serum globulin was divided into tertiles based on the distribution of study subjects (low globulin, ≤ 2.7 g/dl (reference); moderate globulin, 2.7-3.1 g/dl; and high globulin, > 3.1 g/dl). A single endoscopic specialist evaluated the endoscopic findings, and mucosal healing was based on Mayo endoscopic subscore., Results: A total of 277 patients with ulcerative colitis were included in the study. Serum globulin was independently positively associated with diminished or absent vascular markings [moderate: adjusted odds ratio (OR) 3.70 (95% confidence interval, CI: 1.82-7.88) and high: adjusted OR 2.40 (95%CI: 1.20-4.94), p for trend = 0.005]. A similar positive association between globulin and erosion was found [high: adjusted OR 2.00 (95%CI: 1.05-3.86)]. Serum globulin was independently inversely associated with mucosal healing [moderate: adjusted OR 0.37 (95%CI: 0.18-0.73) and high: adjusted OR 0.31 (95%CI: 0.14-0.64), p for trend = 0.001] and adjusted partial mucosal healing [moderate: OR 0.51 (95%CI: 0.26-0.98), p for trend = 0.048]. The inverse association between globulin and mucosal healing was significant in the low but not the high C-reactive protein group., Conclusions: In patients with ulcerative colitis, serum globulin was significantly positively associated with endoscopic activity, and was significantly inversely associated with mucosal healing, especially in the low C-reactive protein group., (© 2021.

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. We evaluated this issue in patients with UC., Methods: Study subjects consisted of 272 Japanese patients with UC. Monocyte counts were taken in the morning after overnight fasting. Monocyte count was divided into tertiles based on the distribution of values among all study subjects. Information on clinical remission was obtained from medical records. MH was assessed using the Mayo endoscopic subscore., Results: The mean monocyte count was 360.1 ± 155.3/mm3. Rates of clinical remission, MH, and complete MH were 61.0%, 66.2%, and 27.9%, respectively. High monocyte count was significantly inversely associated with clinical remission, MH, and complete MH (adjusted odds ratio [OR] 0.45 [95% confidence interval [CI]: 0.23-0.89], OR 0.45 [95% CI: 0.23-0.89], and OR 0.48 [95% CI: 0.23-0.97], respectively). Patients were also classified according to C-reactive protein (CRP) levels; in the low CRP group (<0.1 mg/dL), high monocyte count was independently inversely associated with complete MH but not with clinical remission or MH (OR 0.33 [95% CI: 0.10-0.92], P for trend = 0.027). In the high CRP group, there was no association between monocyte count and clinical outcomes., Discussion: Our findings suggest that peripheral blood monocyte count can be used as a serum supplemental marker for MH in UC patients with low CRP levels., (Copyright © 2021 The Author(s).

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. We evaluated this issue in patients with UC overall and explored whether duration of UC affected this association., Design: This cross-sectional study recruited consecutive patients with UC. Study subjects consisted of 273 Japanese patients with UC. Serum albumin was divided into tertiles based on its distribution in all study subjects. One endoscopy specialist was responsible for measuring partial MH and MH, which were defined as a Mayo endoscopic subscore of 0-1 and 0, respectively. The association between serum albumin and clinical outcomes was assessed by multivariate logistic regression., Results: Rates of clinical remission, partial MH and MH were 57.9%, 63% and 26%, respectively. Only high serum albumin (>4.4 mg/dL) was significantly positively associated with MH (OR 2.29 (95% CI: 1.03 to 5.29), p for trend=0.043). In patients with short UC duration (<7 years) only, high serum albumin was significantly positively associated with MH and clinical remission. In patients with long UC duration (≥7 years), in contrast, no association between serum albumin and clinical outcomes was found., Conclusion: In Japanese patients with UC, serum albumin was significantly positively associated with MH. In patients with short UC duration, serum albumin might be a useful complementary marker for MH., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

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. Information on clinical outcome was collected from medical records. Mucosal healing (MH) and partial MH was defined as a Mayo endoscopic subscore of 0 or 0-1, respectively. Age, sex, BMI, current smoking, current drinking, prednisolone use, and anti-TNFα monoclonal antibody use were selected a priori as potential confounding factors., Results: Study subjects consisted of 294 Japanese patients with UC. Eating at speed moderate and eating quickly were independently inversely associated with MH: the adjusted odds ratios (ORs) were 0.38 (95% confidence interval [CI] 0.16-0.85) and 0.38 (95% CI 0.17-0.81) (p for trend = 0.033). Eating until full was independently inversely associated with MH: the adjusted OR was 0.38 (95% CI 0.27-0.86). MH in patients who skipped breakfast was marginally lower than that in patients who did not skip breakfast. No association between eating habits and clinical remission or partial MH was found., Conclusion: Among patients with UC, eating rate and eating until full may be independently inversely associated with MH but not clinical remission.

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. Thus, we evaluated this issue among Japanese patients with UC., Methods: The study subjects consisted of 304 Japanese patients with UC. Serum total bilirubin and indirect bilirubin were divided into quartiles on the basis of the distribution of all study subjects (low, moderate, high, and very high). Several endoscope specialists were responsible for evaluating MH, which was defined as a Mayo endoscopic subscore of 0. The information on clinical remission was collected using medical records., Results: The mean age was 49.9 years, the percentage of male patients was 59.2%, and the percentage of MH was 29.3%. High serum total bilirubin was independently positively associated with MH (OR 2.26 [95%CI 1.13-4.61]. However, after adjustment for confounding factors, the association between total bilirubin and MH disappeared. Very high serum indirect bilirubin was independently positively associated with MH (OR 2.31 [95%CI 1.10-5.00], p for trend = 0.026). No association between bilirubin and clinical remission was found., Conclusions: Among Japanese patients with UC, serum indirect bilirubin, but not total bilirubin, was significantly positively associated with MH but not clinical remission.

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. We therefore assessed this issue among Japanese patients with UC., Methods: The study subjects consisted of 345 Japanese patients with UC. Platelet count was divided into quartiles on the basis of the distribution of all study subjects (low, moderate, high, and very high). Several endoscope specialists were responsible for evaluating MH and partial MH, which was defined as a Mayo endoscopic subscore of 0 and 0-1, respectively. Estimations of crude odds ratios (ORs) and their 95% confidence intervals (CIs) for partial MH and MH in relation to platelet count were performed using logistic regression analysis. Age, sex, CRP, steroid use, and anti-Tumor necrosis factor α (TNFα) preparation were selected a priori as potential confounding factors., Results: The percentage of partial MH and MH were 63.2 and 26.1%, respectively. Moderate and very high was independently inversely associated with partial MH (moderate: OR 0.40 [95%CI 0.19-0.810], very high: OR 0.37 [95%CI 0.17-0.77], p for trend = 0.034). Similarly, moderate, high, and very high were independently inversely associated with MH (moderate: OR 0.37 [95% CI 0.18-0.73], high: OR 0.41 [95% CI 0.19-0.83], and very high: OR 0.45 [95% CI 0.21-0.94], p for trend = 0.033) after adjustment for confounding factors., Conclusions: Among patients with UC, platelet count was independently inversely associated with MH.

We report a patient who developed ulcerative colitis during the course of primary biliary cirrhosis (PBC). PBC was diagnosed by liver histology when the patient was 31 years old, at which time no symptoms were observed. At 45 years of age, the patient complained of bloody diarrhea and abdominal pain, and she was diagnosed with ulcerative colitis by colonoscopy and histological examination. The patient had HLA-DRB1(*)1502 and (*)0802, which are associated with both diseases. Ulcerative colitis should be considered in the differential diagnosis of bowel disease in patients with PBC. The possible genetic associations between 2 diseases are also discussed.

Purpose: The therapeutic efficacy of lymphocytapheresis in autoimmune diseases is presumed to be caused by depletion of activated lymphocytes. However, nothing is known about the inducer of activated lymphocytes, the antigen-presenting dendritic cells, during lymphocytapheresis., Basic Procedures: Six sessions of lymphocytapheresis were done in five patients with ulcerative colitis. Dendritic cells were enriched from the buffy coat of depleted lymphocytes and also from the peripheral blood. The phenotype and function of dendritic cells were studied by dual-color flow cytometry and in allogenic mixed leukocyte reaction, respectively. The serum levels of inflammatory cytokines (interleukin-1alpha 6, 8, 10, and 12 and tumor necrosis factor-alpha and beta) were measured before and after lymphocytapheresis in all cases., Main Findings: Lymphocytapheresis was safe and caused clinical, endoscopic or histologic improvements in all patients with ulcerative colitis. Many CD83-positive mature dendritic cells were found in the buffy coats after each session of lymphocytapheresis. The function of dendritic cells, the frequencies of CD83-positive dendritic cells and the levels of interleukin-6 and interleukin-8 were down regulated in all patients with ulcerative colitis after lymphocytapheresis compared with their levels before lymphocytapheresis., Conclusions: Depletion and down regulation of the function of dendritic cells and diminished levels of inflammatory cytokines caused by lymphocytapheresis may contribute to the therapeutic efficacy of lymphocytapheresis.
