Comparison of the effects of individual symptoms of gastroesophageal reflux disease co-existing functional dyspepsia on patients' daily lives: A prospective, observational study.

Background and Aim: Patients with gastroesophageal reflux disease (GERD) frequently also have functional dyspepsia (FD) symptoms, which impair their quality of life. However, the magnitude and characteristics of the effects of each symptom on daily life have been unclarified. Using multiple regression analysis, we aimed to clarify these questions. Methods: We enrolled 290 patients from 29 institutions across Japan, in this prospective, observational study. Patients responded to three questionnaires (Gastroesophageal Reflux and Dyspepsia Therapeutic Efficacy and Satisfaction Test [GERD-TEST], Hospital Anxiety and Depression Scale [HADS], and 8-item Short-Form Health Survey [SF-8]) before and after 4 weeks of proton pump inhibitor treatment. Pearson correlation and multiple regression analyses were conducted between symptoms such as typical GERD, epigastric pain syndrome (EPS) and postprandial distress syndrome (PDS) of FD, and aspects of daily life, namely, level of satisfaction with the daily life of GERD-TEST, anxiety and depression score of HADS, and physical and mental component summary of SF-8. Results: Pearson correlation analysis showed a significant correlation in all combinations between GERD/FD-EPS/FD-PDS symptoms and the nine aspects of daily life. However, multiple regression analysis results deviated from these results, with the most significant effects seen in the PDS-symptom subscale (SS) on the five aspects of daily life, that is, dissatisfaction with eating, daily life-SS, anxiety, depression, and mental component summary (MCS) whereas the significant effects in GERD-SS on five aspects of daily life, that is, dissatisfaction for eating, anxiety, depression, physical component summary, and MCS, disappeared. Conclusion: Dealing with co-existing FD symptoms without overlooking them may be important in the management of GERD.

[Intravascular large B-cell lymphoma diagnosed by total hysterectomy].

Intravascular large B-cell lymphoma (IVLBCL) is a rare form of non-Hodgkin B-cell lymphoma which occurs mainly in capillaries and small blood vessels. Successful diagnosis of IVLBCL is challenging since it lacks tumor formation and presents various clinical manifestations. An 82-year-old Asian female patient presented to our emergency department with a history of general fatigue, weight loss, and fever for two weeks. The patient's random skin biopsy was negative, and her bone marrow biopsy revealed hemophagocytic syndrome with no obvious involvement of lymphoma cells. Gallium scintigraphy showed mild uptake in the uterus, pelvis, and spine. The repetitive bone marrow biopsy result and the endometrial cytology/biopsy were negative; however, the pelvic MRI was compatible with lymphoma, revealing lesions in the corpus uteri, pelvis, and vertebral body. After laparoscopic-assisted vaginal total hysterectomy and bilateral salpingo-oophorectomy, the diagnosis of the Asian variant of IVLBCL was made. Although total hysterectomy remains controversial for elderly patients with declining performance status, we could successfully diagnose the condition and initiate the treatment. The patient's general condition improved soon after starting rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone regimen on day 26, and she was discharged on day 45.

Contribution of Capsule Endoscopy Early in a Bleeding Episode to Treatment of Small Bowel Angioectasia: A Case Report.

Background: Recent advances in endoscopic devices such as small bowel capsule endoscopy and balloon-assisted endoscopy have improved the level of medical care for small bowel bleeding. However, treating small bowel angioectasia remains challenging because repeated intermittent bleeding can occur from the multiple minute lesions (about 1 mm in size) that develop in a synchronous and metachronous manner. Here, we report a case of small bowel angioectasia in which capsule endoscopy performed early in a bleeding episode contributed to treatment. Case Summary: A 66-year-old man with suspected small bowel bleeding underwent small bowel capsule endoscopy and balloon-assisted endoscopy with argon plasma coagulation hemostasis for a small intestinal angioectasia. Because small bowel bleeding recurred intermittently after the treatment, small bowel capsule endoscopy and balloon-assisted endoscopy were repeated when there was no bleeding, but no abnormalities were found. Subsequent small bowel capsule endoscopy during a bleeding episode revealed bloody intestinal fluid in the proximal small intestine. Peroral balloon-assisted endoscopy was performed 2 days after SBCE for detailed observation of the small intestinal mucosa at the suspected bleeding site, and there a 1-mm Dieulafoy's lesion with no active bleeding was identified. We performed argon plasma coagulation, and no bleeding was observed thereafter. Conclusions: Small bowel capsule endoscopy immediately after bleeding onset can identify the bleeding source of multiple minute lesions in small bowel angioectasia.

Megaesophagus and Megaduodenum Found Incidentally on a Routine Chest Radiograph During a Health Examination.

Chronic idiopathic intestinal pseudo-obstruction (CIIP) caused by impaired intestinal peristalsis leads to intestinal obstructive symptoms. A 20-year-old man had marked esophageal dilatation that was found incidentally on chest radiography during a health examination. Chest/abdominal contrast-enhanced computed tomography and endoscopy showed marked esophageal and duodenal dilatation without mechanical obstruction. Upper gastrointestinal series and high-resolution esophageal manometry revealed absent peristalsis in the dilated part. CIIP was suspected in the patient's father, suggesting familial CIIP. The patient likely had signs of pre-onset CIIP. This is the first case of suspected CIIP in which detailed gastrointestinal tract examinations were performed before symptoms appeared.

Clinical features and therapeutic responses to proton pump inhibitor in patients with severe reflux esophagitis: A multicenter prospective observational study.

BACKGROUND AND AIM: In patients with severe erosive reflux disease (ERD; Los Angeles classification grade C/D) who do not undergo endoscopic examination, insufficient strength and duration of proton pump inhibitor (PPI) therapy may lead to complications such as esophageal bleeding and stenosis. Therefore, to provide a safe and effective treatment for gastroesophageal reflux disease (GERD), we investigated the clinical features of patients with severe ERD and their responses to PPI therapy. METHODS: Patients with GERD symptoms received PPI therapy for 4 weeks after endoscopic examination. The patients completed the Gastroesophageal reflux and dyspepsia therapeutic efficacy and satisfaction test questionnaire before and 2 or 4 weeks after PPI treatment. Patient characteristics, presence/absence of coexisting atrophic gastritis (AG) and hiatus hernia (HH), and responses to PPI therapy were compared in patients with GERD among three groups (nonerosive reflux disease, mild ERD [grade A/B], and severe ERD). RESULTS: The severe ERD group had a significantly higher proportion of males, higher body mass index, and longer duration of GERD morbidity. Furthermore, the severe ERD group also had a significantly lower incidence of coexisting AG and higher incidence of HH. There was no difference in the severity of GERD before PPI treatment among the three groups. Unexpectedly, the response to PPI therapy was the best in the severe ERD group. CONCLUSION: Sufficient strength and period of PPI therapy are required, even if the symptoms show early improvement, when treating GERD patients without performing endoscopy, considering the possibility of severe ERD.

The early therapeutic response at 2 weeks is a crucial predictor of proton pump inhibitor-refractory gastroesophageal reflux disease.

BACKGROUND: In recent years, the prevalence of proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease (GERD) has been increasing, posing a clinical obstacle to improving the management of GERD patients. The ability of known predictive factors to explain therapeutic response to PPI remains insufficient. Therefore, we examined whether the addition of early therapeutic response to PPI as an explanatory variable may increase the predictive power for PPI-refractory GERD. METHODS: The severity and therapeutic response of GERD symptoms to PPI were evaluated using the GastroEsophageal Reflux and Dyspepsia Therapeutic Efficacy and Satisfaction Test (GERD-TEST) questionnaire at baseline and at 2 and 4 weeks after treatment. The relevance of the therapeutic effect of PPI at 2 weeks compared to that at 4 weeks was examined in 301 patients with GERD. Independent predictive factors for refractory GERD at 4 weeks of PPI therapy were examined in 182 patients. The effect of various clinical factors, including the early response to PPI, was assessed using multiple regression analysis. RESULTS: The number of PPI-therapy responders increased significantly with the duration of treatment (p < 0.0001). The response to PPI therapy at 2 weeks was significantly correlated with that at 4 weeks (p < 0.0001). Multiple regression analysis revealed that the therapeutic response to PPI at 2 weeks was by far the strongest predictor of the therapeutic effect at 4 weeks among all clinical factors. CONCLUSIONS: Medication change for PPI-refractory GERD at 2 weeks may be an efficacious therapeutic strategy to improve patients' quality of life.

Mesalazine formulation intolerance due to suspected excipient allergy in the treatment of ulcerative colitis: a case report.

Mesalazine formulations are essential for treating ulcerative colitis (UC), and intolerance to these formulations complicates the treatment of this condition. Some cases of mesalazine formulation intolerance are caused by the excipients rather than the active ingredient mesalazine. Therefore, mesalazine administration can be continued in such cases by changing the mesalazine formulation. This report describes a case of intolerance to mesalazine in which UC was effectively treated by switching mesalazine formulations. A drug-induced lymphocyte stimulation test suggested that allergy to the additive povidone was the cause of mesalazine formulation intolerance. This is the first case study to identify an additive that caused mesalazine formulation intolerance.

Proton pump inhibitor monotherapy is effective to attenuate dyspepsia symptoms associated with gastroesophageal reflux disease: a multicenter prospective observational study.

BACKGROUND AND AIM: Gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) are frequently overlapped. However, no treatment strategies have been established yet for such patients. This study compared the effects of proton pump inhibitor (PPI) treatment in patients with GERD-associated FD among three groups with varying severity levels of GERD symptoms. METHODS: The patients with GERD and FD symptoms received PPI treatment for 4 weeks after endoscopy, and the severity of the symptoms and responses to treatment were evaluated at before and after 4 weeks of treatment using the Gastroesophageal Reflux and Dyspepsia Therapeutic Efficacy and Satisfaction Test (GERD-TEST). The patients were divided into three groups in accordance with the severity of the GERD symptoms as assessed by the GERD symptom subscale (SS) scores of pre-treatment. RESULTS: Data from 233 cases of 40 mild, 151 moderate and 42 severe symptoms were analyzed. Analysis of the pre-treatment scores for each symptom revealed that a higher GERD-SS score was significantly associated with higher scores on any kind of FD score. Four weeks of PPI treatment significantly and markedly alleviated any of GERD/FD symptoms. Most importantly, change in the score for each symptom after 4 weeks of treatment relative to the pre-treatment score was significantly greater in the groups with more severe GERD-SS. CONCLUSION: FD symptoms associated with more severe GERD symptoms are supposed to be acid-related dyspepsia, and PPI monotherapy is recommended as the treatment of first choice in such patients.

Seven days triple therapy for eradication of Helicobacter pylori does not alter the disease activity of patients with inflammatory bowel disease.

BACKGROUND/AIMS: The influences of Helicobacter pylori eradication therapy on the disease course of inflammatory bowel disease (IBD) are still unclear. We therefore conducted a multicenter, retrospective cohort study to evaluate the safety of H. pylori eradication therapy for IBD patients. METHODS: IBD patients with H. pylori eradication from 2005 to 2015 (eradication group) and control patients (non-eradication group; 2 paired IBD patients without H. pylori eradication matched with each eradicated patient) were included. IBD exacerbation (increased/additional IBD drug or IBD-associated hospitalization/surgery) and disease improvement based on the physicians' global assessment were investigated at baseline, and at 2 and 6 months after eradication or observation. RESULTS: A total of 429 IBD (378 ulcerative colitis, 51 Crohn's disease) patients, comprising 144 patients in the eradication group and 285 patients in the non-eradication group, were enrolled at 25 institutions. IBD exacerbation was comparable between groups (eradication group: 8.3% at 2 months [odds ratio, 1.76; 95% confidence interval, 0.78-3.92; P=0.170], 11.8% at 6 months [odds ratio, 1.60; 95% confidence interval, 0.81-3.11; P=0.172]). Based on the physicians' global assessment at 2 months, none of the patients in the eradication group improved, whereas 3.2% of the patients in the non-eradication group improved (P=0.019). Multivariate analysis revealed that active disease at baseline, but not H. pylori eradication, was an independent factor for IBD exacerbation during 2 months' observation period. The overall eradication rate was 84.0%-comparable to previous reports in non-IBD patients. CONCLUSIONS: H. pylori eradication therapy does not alter the short-term disease activity of IBD.
