Evaluation of scoring models for identifying the need for therapeutic intervention for upper gastrointestinal bleeding: a new prediction score model for Japanese patients

Multiple scoring systems have been developed to predict outcomes in patients with upper gastrointestinal bleeding. We determined how well these and a newly established scoring model predict the need for therapeutic intervention, excluding transfusion, in Japanese patients with upper gastrointestinal bleeding.

Influence of endoscopic submucosal dissection on serum levels of pepsinogens in patients with early gastric cancer

Background:  The serum levels of pepsinogens (PG) have been considered to be a useful marker for assessing the risk of metachronous gastric cancer in patients who undergo endoscopic submucosal dissection. However, the influence of endoscopic submucosal dissection (ESD) on serum levels of PG has not yet been examined. The aim of this study was to examine whether the level of PG after ESD can be used to predict the risk of metachronous cancer.

Biliary drainage improves the predictive value of modified Glasgow Prognostic Scores in inoperable pancreatic cancer

Objective To assess the influence of biliary drainage to cholangitis on modified Glasgow Prognostic Score (mGPS) in patients with pancreatic cancer. Methods mGPS was calculated before and after biliary drainage in 47 consecutive patients with inoperable pancreatic cancer who were receiving chemotherapy. Biliary drainage was indicated for malignant obstructive jaundice that prevented the administration of chemotherapy. To elucidate mGPS values, serum levels of CRP and albumin were measured at the time of diagnosis (before biliary drainage). Overall survival was evaluated and risk factors, which contribute to overall survival, were examined. Results Biliary drainage was performed in 15 patients. Using values obtained before biliary drainage, there were no significant differences in median survival time between patients with a mGPS of 0 and those with a mGPS of 1 or 2 (10.7 vs. 9.4 months; p = 0.757). However, using values obtained after biliary drainage, median survival time was significantly higher in patients with a mGPS of 0 than in those with a mGPS of 1 or 2 (11.4 vs. 4.7 months; p = 0.002). Multivariate analysis revealed that a mGPS of 1 or 2 (HR: 3.38; 95% CI: 1.35–8.46, p = 0.009), a carbohydrate antigen 19–9 >1000 U/mL (2.52; 1.22–5.23, p = 0.013), a performance status of 2 (7.68; 2.72–21.28, p = 0.001), carcinoembryonic antigen level >10 ng/mL (2.29; 1.13–4.61, p = 0.021) were independently associated with overall survival. Conclusion mGPS values obtained after biliary drainage appear to be a more reliable indicator of overall survival in patients with inoperable pancreatic cancer.

Usefulness of the Glasgow–blatchford score to predict 1-week mortality in patients with esophageal variceal bleeding

Objectives Esophageal variceal bleeding is one of the most severe complications of liver cirrhosis, with high mortality. However, there is no established scoring system for short-term mortality in patients with esophageal variceal bleeding. The aim of this study was to evaluate the usefulness of the Glasgow–Blatchford score (GBS), the Model for End-Stage Liver Disease (MELD) score, and the Child–Pugh score for predicting short-term and hospital mortality in patients with esophageal variceal bleeding. Methods A total of 47 patients with esophageal variceal bleeding were studied between September 2009 and March 2015. The GBS, the MELD score, and the Child–Pugh score were assessed for their ability to predict 1- and 6-week mortality rates using a receiver operating characteristic curve. Results The 1- and 6-week mortality rates were 17.0 and 31.9%, respectively. The median GBS, MELD, and Child–Pugh scores were 13 (range: 4–19), 10 (range: 0–34), and 9 (range: 5–13), respectively. The GBS was superior to both the MELD and the Child–Pugh scores for prediction of 1-week mortality [area under the curve=0.82 (95% confidence interval: 0.66–0.98) vs. 0.71 (0.47–0.96) and 0.72 (0.53–0.91)]. The MELD score was superior to both the Child–Pugh score and the GBS for prediction of 6-week mortality [area under the curve=0.83 (95% confidence interval: 0.69–0.97) vs. 0.69 (0.52–0.85) and 0.67 (0.50–0.83)]. Conclusion For 1-week mortality, the GBS was superior to the Child–Pugh and the MELD scores in patients with esophageal variceal bleeding. However, for 6-week mortality, the MELD score was superior in patients with esophageal variceal bleeding.OBJECTIVES Esophageal variceal bleeding is one of the most severe complications of liver cirrhosis, with high mortality.

Decrease of Estradiol and Several Lifestyle Factors, but Not Helicobacter pylori Infection, Are Significant Risks for Osteopenia in Japanese Females

Background: The primary cause of osteoporosis in women is increased bone resorption and decreased bone density associated with reduced estrogen secretion. Several studies have demonstrated a relationship between Helicobacter pylori infection and osteoporosis regardless of estrogen levels. This study examined the relationship between H. pylori infection and osteopenia together with estrogen levels, calcium intake, and several lifestyle factors. Methods: This study included 473 healthy women who underwent a general health examination. Multivariate analysis was performed, with age, body mass index (BMI), smoking habit, drinking habit, exercise habit, schooling duration, estradiol levels, birth history, calcium intake, schooling duration, smoking habit, drinking habit, exercise habit, and H. pylori infection as independent variables and the presence of osteopenia as a dependent variable. Results: The adjusted OR for osteopenia with H. pylori infection was 0.95 (95% CI 0.55-1.63, p = 0.84). In contrast, osteopenia was significantly associated with age, low BMI, lesser schooling period, low estradiol levels, and low calcium intake. Conclusions:H. pylori infection was not a significant risk for osteopenia by the multivariate analysis, which included the primary confounding factors. Significant factors, such as estradiol and calcium intake, should be assessed together to study the association of H. pylori infection and osteopenia.

Validity of the Pre-endoscopic Scoring Systems for the Prediction of the Failure of Endoscopic Hemostasis in Bleeding Gastroduodenal Peptic Ulcers

Objective Although several pre-endoscopic scoring systems have been used to predict the mortality or the need for intervention for upper gastrointestinal bleeding, their usefulness to predict the failure of endoscopic hemostasis in bleeding gastroduodenal peptic ulcers has not yet been fully investigated. In this study, we evaluated the usefulness of the Glasgow-Blatchford score (GBS), the clinical Rockall score (CRS), and the AIMS65 score in predicting the failure of endoscopic hemostasis in patients with bleeding gastroduodenal peptic ulcers. Methods We retrospectively evaluated 226 consecutive emergency endoscopic cases with bleeding gastroduodenal peptic ulcers between April 2010 and September 2016. The study outcome was the failure of first endoscopic hemostasis. The GBS, CRS, and AIMS65 scores were assessed for their ability to predict the failure of endoscopic hemostasis using a receiver-operating characteristic curve. Results Eight cases (3.5%) failed to achieve first endoscopic hemostasis. Surgery was required in six cases, and interventional radiology was required in two cases. The GBS was superior to both the CRS and the AIMS65 score in predicting the failure of endoscopic hemostasis [area under the curve, 0.77 (95% confidence interval, 0.64-0.90), 0.65 (0.56-0.74) and 0.75 (0.56-0.95), respectively]. No failure of endoscopic hemostasis was noted in cases in which the patient scored less than GBS 10 and CRS 2. Conclusion The GBS was the most useful scoring system for the prediction of failure of endoscopic hemostasis in patients with bleeding gastroduodenal peptic ulcers. The GBS was also useful in identifying the patients who did not require surgery or interventional radiology.

Infection of Helicobacter pylori and Atrophic Gastritis Influence Lactobacillus in Gut Microbiota in a Japanese Population

Background Suppression of gastric acid by proton pump inhibitors is associated with the increase of Lactobacillus in human gut microbiota. Gastric acid secretion is also suppressed by Helicobacter pylori infection and following atrophic gastritis. However, few studies have examined the association between H. pylori infection and Lactobacillus species in gut microbiota particularly in Japan. Methods A total of 1,123 adult subjects who participated in a health survey in Hirosaki City were studied. Infection of H. pylori was defined by both serum antibody and stool antigen test. The presence and the severity of atrophic gastritis were defined by the serum level of serum pepsinogens. Using 16S ribosomal RNA amplification from fecal samples, the relative abundance of Lactobacillus was calculated, and the composition ratio of each Lactobacillus species was surveyed. Results The relative abundance of the Lactobacillus in H. pylori-infected subjects with severe atrophic gastritis was higher comparing with those in subjects with mild atrophic gastritis and without atrophic gastritis (0.591 vs 0.068% and 0.033%, respectively; p < 0.001) and also that of non-infected subjects (0.033%; p < 0.001). In H. pylori non-infected subjects, both gender and age were not associated with the relative abundance of Lactobacillus in fecal samples. The proportion of Lactobacillus salivarius was high in H. pylori-infected subjects while that of Lactobacillus acidophilus was high in non-infected subjects. Conclusion Lactobacillus in human gut microbiota could be influenced by H. pylori infection and severity of atrophic gastritis in Japanese subjects.

Comparable efficacy of endoscopic transpapillary gallbladder drainage and percutaneous transhepatic gallbladder drainage in acute cholecystitis

Background and study aims  Although endoscopic transpapillary gallbladder drainage (ETGBD) is reportedly useful in patients who have acute cholecystitis, its efficacy has not been compared to that of percutaneous transhepatic gallbladder drainage (PTGBD). We retrospectively compared the efficacy and safety of ETGBD and PTGBD in patients with acute cholecystitis. Patients and methods  We studied 75 patients who required gallbladder drainage for acute cholecystitis between January 2014 and December 2016. Using propensity score matching analysis, we compared the clinical efficacy and length of hospitalization in patients successfully treated with ETGBD and PTGBD. Moreover, we assessed the predictive factors for hospitalization period < 30 days using multivariate analysis. Results  ETGBD and PTGBD were successfully performed in 33 patients (77 %) and 42 patients (100 %) ( P  < 0.001). Twenty-seven matched pairs were obtained after propensity score matching analysis. No significant differences were observed between patients treated with ETGBD and those treated with PTGBD with respect to improvement in white blood cell count and serum C-reactive protein level. The length of hospitalization in patients treated with ETGBD was significantly shorter than in those treated with PTGBD regardless of the need for surgery. Multivariate logistic regression analysis revealed ETGBD (odds ratio, 7.07; 95 % confidence interval 2.22 – 22.46) and surgery (odds ratio 0.26; 95 % confidence interval 0.09 – 0.79) as independent factors associated with hospitalization period. There were no significant differences in occurrence of complications in ETGBD and PTGBD procedure. Conclusions  ETGBD was shown to be as useful as PTGBD for treatment of acute cholecystitis and was associated with shorter hospitalization period. ETGBD can be an alternative treatment option for acute cholecystitis at times when PTGBD is not possible.
