Comparison of fecal calprotectin levels and endoscopic scores for predicting relapse in patients with ulcerative colitis in remission.

Background: Although the usefulness of endoscopic scores, such as the Mayo Endoscopic Subscore (MES), Ulcerative Colitis Endoscopic Index of Severity (UCEIS), and Ulcerative Colitis Colonoscopic Index of Severity (UCCIS), and biomarkers such as fecal calprotectin (FC) for predicting relapse in ulcerative colitis (UC) has been reported, few studies have included endoscopic scores for evaluating the entire colon.

Aim: To compare the usefulness of FC value and MES, UCEIS, and UCCIS for predicting relapse in patients with UC in clinical remission.

Methods: In total, 75 patients with UC in clinical and endoscopic remission who visited our institution between February 2019 and March 2022 were enrolled.

Intrahepatic cholangiocarcinoma in patients with primary sclerosing cholangitis and ulcerative colitis: Two case reports.

Background: Primary sclerosing cholangitis (PSC) is an extraintestinal manifestation of ulcerative colitis (UC). PSC is a well-known risk factor for intrahepatic cholangiocarcinoma (ICC), and ICC is known to have a poor prognosis.

Case Summary: We present two cases of ICC in patients with PSC associated with UC.

Importance of eosinophilic infiltration of the colonic mucosa in ulcerative colitis patients who are refractory to maintenance therapy: A prospective, single-center study.

Eosinophilic infiltration is sometimes observed histologically in ulcerative colitis (UC), but the effect of the degree of infiltration on the treatment course for UC is not completely understood. We investigated whether short-term steroid administration in UC patients refractory to maintenance therapy, with high eosinophilic infiltration in the colonic mucosa, contributed to the clinical and endoscopic improvement. Ten patients with endoscopically active and pathologically high eosinophilic infiltration, based on pathological examination using endoscopic biopsy, were examined for the clinical background when starting steroid treatment.

Modified method of patency judgement using patency capsule prior to capsule endoscopy in clinical practice.

In 2012, Japan approved the use of a tag-less patency capsule (PC), which evaluates gastrointestinal patency before small-bowel capsule endoscopy (SBCE). This study aimed to evaluate the validity of our modification on the passage criteria for this PC in clinical practice. We retrospectively enrolled 326 consecutive patients who underwent PC examination before SBCE.

Lymphocyte to monocyte ratio and serum albumin changes predict tacrolimus therapy outcomes in patients with ulcerative colitis.

Tacrolimus therapy for ulcerative colitis is ineffective in certain patients; these patients require biologics or colectomy. We examined the ability of serum albumin levels and leukocyte subtypes to predict the therapeutic efficacy of tacrolimus. Patients with ulcerative colitis treated with tacrolimus were divided into non-failure and failure (required colectomy or switch to biologics or systemic steroids) groups.

Predicting Ulcerative Colitis Relapse in Clinical Remission With Fecal Immunochemical Occult Blood Test or Prostaglandin E-Major Urinary Metabolite.

Introduction: The fecal immunochemical occult blood test (FIT) and prostaglandin E-major urinary metabolite (PGE-MUM) have been reported to predict the relapse of ulcerative colitis (UC) during remission. In this study, we directly compared FIT and PGE-MUM in predicting relapse and examined the effect of disease duration on these biomarkers.

Methods: Measurements of 2 biomarkers and endoscopic examination were performed in 73 patients with UC in remission.

Real-World Efficacy and Safety Monitoring for Predicting Continuation of Tofacitinib Therapy in Patients with Ulcerative Colitis.

Background: Although the clinical efficacy of tofacitinib in patients with ulcerative colitis (UC) has been assessed in the OCTAVE trial, there is a lack of adequate data on its efficacy in real-world clinical settings.

Aims: To analyze the efficacy of tofacitinib and the predictors of its continuation.

Methods: Changes in clinical activity index (CAI), blood test results (C-reactive protein [CRP], albumin [Alb], and hemoglobin), and endoscopic scores (Mayo endoscopic subscore [MES], ulcerative colitis endoscopic index of severity [UCEIS]) were evaluated, and we investigated the factors that affect the rate and continuity of tofacitinib.

Further research on the clinical relevance of the ulcerative colitis colonoscopic index of severity for predicting 5-year relapse.

Purpose: The ulcerative colitis colonoscopic index of severity (UCCIS) evaluates the state of the entire colonic mucosa in ulcerative colitis. However, no cut-off values of scores for predicting clinical relapse in patients with ulcerative colitis have been established. This study aimed to determine the cut-off values for predicting clinical relapse in patients with ulcerative colitis.

Usefulness of the capsule endoscopy Crohn's disease activity index in assessing the necessity of early additional treatment in patients with Crohn's disease in clinical remission.

The Capsule Endoscopy Crohn's Disease Activity Index (CECDAI) was recently reported as a new scoring system to evaluate the mucosal lesions of patients with Crohn's disease (CD). We investigated whether CECDAI is useful for assessing the necessity of early additional treatment in patients with CD in clinical remission.Twenty-one patients with small intestinal CD in clinical remission underwent capsule endoscopy (CE).

Comparison between Prostaglandin E-major urinary metabolite and C-reactive protein levels to reflect endoscopic scores in patients with ulcerative colitis.

Prostaglandin E-major urinary metabolite (PGE-MUM) and C-reactive protein (CRP) are useful biomarkers in patients with ulcerative colitis. However, whether changes in endoscopic scores over time are reflected in the values of these biomarkers has not been verified. This prospective observational study aimed to assess the relationship between changes in biomarker levels and endoscopic scores in patients with ulcerative colitis.

Prevalence of UL97 gene mutations and polymorphisms in cytomegalovirus infection in the colon associated with or without ulcerative colitis.

Cytomegalovirus (CMV) reactivation in the colon is common in patients with severe ulcerative colitis (UC). Ganciclovir (GCV) resistance conferring CMV UL97 gene mutations have been reported in recent years. However, the prevalence of UL97 gene mutations in GCV-naive CMV infection in the colon remains unknown.

Early serum albumin changes in patients with ulcerative colitis treated with tacrolimus will predict clinical outcome.

Background: Oral tacrolimus is a therapeutic agent for moderate to severe steroid-dependent or resistant ulcerative colitis (UC), but remission induction is difficult, and it is necessary to treat the patient while considering the next treatment.

Aim: To examine serum albumin (Alb) level as a prognostic factor for the therapeutic effect of tacrolimus in clinical practice.

Methods: Forty-seven patients with UC treated with tacrolimus at our institution were divided into remission and failure groups (colectomy or switch to biologics), and the biological data at the start of observation and at weeks 1 and 2 were retrospectively examined.

C-reactive protein is superior to fecal biomarkers for evaluating colon-wide active inflammation in ulcerative colitis.

We evaluated the association between endoscopic scores of colonic inflammation and fecal calprotectin (FC), fecal immunochemical occult blood test (FIT), and C-reactive protein (CRP) in patients with ulcerative colitis (UC). Endoscopic scores reflecting the most severe lesion [maximum Mayo Endoscopic Subscore (M-MES) and Ulcerative Colitis Endoscopic Index of Severity (UCEIS)] and those reflecting the inflammation of the entire colon [sum of MES (S-MES) and Ulcerative Colitis Colonoscopic Index of Severity (UCCIS)] were evaluated. FC, FIT, and CRP were measured, and their association with the four endoscopic scores was evaluated.

Serum N-terminal telopeptide of type I collagen as a biomarker for predicting bone density loss in patients with Crohn disease.

Background: The serum N-terminal telopeptide of type I collagen (NTx) is significantly higher in patients with Crohn disease (CD) than in healthy individuals and patients with ulcerative colitis. This study aimed to investigate whether an elevated serum NTx level is a risk predictor of osteoporosis in patients with CD.

Methods: Based on whether the femoral Z-score decreased over a 2-year period, 41 CD patients were divided into the ΔZ-score <0 group (Z-score decreased) and the ΔZ-score ≥0 group (Z-score did not decrease).

Evaluation of the modified Crohn's disease activity index in patients with Crohn disease with enterostomy: A single-center observational study.

Although the Crohn's Disease Activity Index (CDAI) is often used to evaluate the disease activity in Crohn's disease (CD), the number of liquid or soft stools cannot be precisely evaluated, and thus accurate scores cannot be calculated, in patients with enterostomy. Therefore, we created the modified CDAI (mCDAI), without the defecation frequency item from the CDAI, and examined its usefulness.Study participants comprised 9 patients with CD with enterostomy and 20 patients with CD without enterostomy.

Prostaglandin E-Major Urinary Metabolite Predicts Relapse in Patients With Ulcerative Colitis in Clinical Remission.

Introduction: Prostaglandin E-major urinary metabolite (PGE-MUM) is a novel biomarker reflecting endoscopic activity in ulcerative colitis (UC). However, there are no studies investigating the efficacy of PGE-MUM as a biomarker for predicting relapse. We investigated whether PGE-MUM can predict clinical relapse of UC.

Tuberous sclerosis patient with neuroendocrine carcinoma of the esophagogastric junction: A case report.

Background: Tuberous sclerosis complex (TSC) is a rare inherited disease with non-cancerous tumor growths in the skin, brain, kidneys, heart, and lungs. The co-occurrence of neuroendocrine neoplasm (NEN) with TSC is even rarer. There have been few reports on the relationship between TSC and neuroendocrine tumors (NETs), and fewer on the relationship between TSC and neuroendocrine carcinoma (NEC), a subtype of NEN.

Mesalazine granule formulation improves clinical data in Crohn's disease compared with tablet formulation.

The efficacy of sustained-release preparations of mesalazine as a remission maintenance treatment for Crohn's disease remains to be established. We aimed to examine the changes in compliance rate and clinical data 2 years after switching from mesalazine tablet to granule formulation at our facility among patients with Crohn's disease in remission. We investigated the rate of continuous treatment of mesalazine granules and examined the changes in Crohn's Disease Activity Index (CDAI) and serum C-reactive protein (CRP), albumin, and hemoglobin (Hb) levels 2 years after the switch.
