Ulcerative Colitis Associated with Cardiometabolic Disease and Complicated with Autoimmune Pancreatitis.

Diet-related cardiometabolic diseases and inflammatory bowel disease, common previously in Western countries, are global problems. We hypothesized that inflammatory bowel disease is a lifestyle disease primarily mediated by the current Western diet. We report here the simultaneous onset of ulcerative colitis and autoimmune pancreatitis, a rare systemic complication of inflammatory bowel disease, 2 months after acute myocardial infarction in a patient with type 2 diabetes. A 67-year-old man with type 2 diabetes was referred to us because of newly diagnosed ulcerative colitis 2 months after acute myocardial infarction. A plant-based diet was provided during hospitalization. An abrupt deterioration in plasma glucose and hemoglobin A1c due to asymptomatic type 2 autoimmune pancreatitis was observed. Prednisolone administration under intensive insulin therapy led to the remission of both diseases. This case was an illustrative one of association between cardiometabolic diseases and inflammatory bowel diseases caused by current unhealthy diets and their shared pathogenesis.

Successful Treatment of Bilocular Walled-off Necrosis with Transmural Naso-cyst Continuous Irrigation: A Case Report.

Recently, transmural naso-cyst continuous irrigation (TNCCI) has been reported as an effective and safe treatment for walled-off necrosis (WON). We herein report a case of bilocular WON that was successfully treated with TNCCI. The patient was a 60-year-old man. The patient underwent endoscopic ultrasound-guided cyst drainage of the main cavity and subcavity using a single transluminal gateway transcystic multiple drainage technique, which was ineffective. Subsequently, a lumen-apposing metal stent (LAMS) was placed in the main cavity and TNCCI was successfully performed in the subcavity. TNCCI with LAMS was effective in treating bilocular WON.

Impact of Functional Status on Development of Clostridioides difficile Infection and Increase in Inhospital Mortality among Antibiotic Users.

INTRODUCTION: Functional status is one of the surrogates of advanced age, an established risk factor for Clostridioides difficile infection (CDI). We aimed to investigate the usefulness of functional status in the clinical management of CDI. METHODS: We enrolled all hospitalized adult patients receiving antibiotics from a retrospective hospital-based cohort in Japan between 2016 and 2020. Using the Barthel index (BI), which is an objective scale of functional status, we investigated the association of BI with developing CDI and its impact on inhospital mortality in patients with CDI. RESULTS: We enrolled 17,131 patients with 100 cases of CDI. Multivariable analysis revealed that lower BI (≤25) was an independent risk factor for developing CDI (adjusted odds ratio, 4.11; 95% confidence interval, 2.62-6.46). Furthermore, a combination of BI and Charlson comorbidity index (CCI) showed an adjusted odds ratio of 36.40 (95% confidence interval, 17.30-76.60) in the highest risk group. A high-risk group according to the combination of BI and CCI was estimated to have significantly higher inhospital mortality in patients with CDI using the Kaplan-Meier method (p = 0.017). A combination of lower BI and higher CCI was an independent predictor of inhospital mortality even in the multivariable Cox regression model (adjusted hazard ratio, 3.00; 95% confidence interval, 1.01-8.88). CONCLUSIONS: Assessment of functional status, especially combined with comorbidities, was significantly associated with developing CDI and may also be useful in predicting inhospital mortality.

Vonoprazan poses no additional risk of developing Clostridioides difficile infection compared to proton pump inhibitors.

BACKGROUND AND AIM: The use of proton pump inhibitors (PPIs) has been repeatedly reported as a trigger of Clostridioides difficile infection (CDI), a leading cause of nosocomial diarrhea. However, only a few studies have reported on the association between vonoprazan, a novel potassium-competitive acid blocker providing potent acid suppression, and CDI, with no studies having been conducted in a clinical setting. We therefore evaluated the association between various classes of acid suppressants and CDI with special attention paid to differences in the magnitudes of association between PPIs and vonoprazan. METHODS: A retrospective hospital-based cohort from a secondary-care hospital in Japan (n = 25 821) was collected, wherein eligible CDI cases were defined as hospital-onset cases (n = 91). A multivariable adjusted logistic regression analysis for the entire cohort and propensity analyses for subgroups consisting of PPI and/or vonoprazan users at various doses (n = 10 306) were performed. RESULTS: The overall CDI incidence rate was 1.42/10 000 patient-days, which was comparable with previous reports. A multivariable analysis showed that both PPIs and vonoprazan were positively associated with CDI (odds ratios [95% confidence intervals]: 3.15 [1.67-5.96] and 2.63 [1.01-6.88], respectively). In addition, matched subgroup analyses showed that PPIs and vonoprazan had equivalent magnitudes of association with CDI. CONCLUSIONS: We found that both PPIs and vonoprazan were associated with CDI, and the magnitude of the association was comparable. Because vonoprazan is widely available in Asian countries, further studies on the association of its usage with CDI are warranted.

A Preoperative Diagnosis of Advanced Cystic Duct Carcinoma Using SpyGlass DS Cholangioscopy: A Report of Two Cases.

Primary cystic duct carcinoma is a rare tumor. The curative treatment of cystic duct carcinoma is complete surgical resection, for which the evaluation of local extension is important. We herein report two cases of cystic duct carcinoma in which a preoperative examination was performed using per-oral cholangioscopy (POCS). Both patients underwent POCS due to suspicion of cystic duct carcinoma based on imaging findings. A visual analysis and biopsy were performed to evaluate local extension, which led to surgery. These cases suggest that POCS is useful for the preoperative assessment of local extension in advanced cystic duct carcinoma.

Extremely Late Recurrence of Ovarian Carcinoma Diagnosed by an Endoscopic Ultrasound-guided Fine-needle Biopsy.

We herein report a case of recurrence of epithelial ovarian carcinoma 41 years after the primary surgery that was diagnosed by an endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB). The differential diagnosis based on the imaging findings was difficult. We performed an EUS-FNB and compared the EUS-FNB specimen to the surgical specimen that had been resected in the primary surgery for ovarian carcinoma 41 years earlier, including immunohistochemical staining. Finally, we made a definitive diagnosis of extremely late recurrence of ovarian carcinoma of the retroperitoneum. An EUS-FNB enables an accurate histological diagnosis by obtaining a sample that is large enough to perform immunohistochemical staining.

Sarcoidosis with Splenic Involvement Diagnosed with Endoscopic Ultrasound-guided Fine-needle Aspiration.

Splenic sarcoidosis is often diagnosed by splenectomy or an ultrasound-guided splenic biopsy. However, splenectomy is invasive and costly, and a percutaneous biopsy is sometimes difficult. We herein report a case of splenic sarcoidosis diagnosed with endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). A 71-year-old man was referred to our hospital for abnormal shadows on a chest roentgenogram. Computed tomography showed multiple lesions in the spleen and pulmonary consolidations. Bronchoscopy revealed no definitive diagnosis. We therefore performed EUS-FNA for a splenic lesion that led to the diagnosis. This case suggests that EUS-FNA is useful in confirming the diagnosis of sarcoidosis with suspected splenic lesions.
