Reported causes include advanced chronic liver disease (ACLD), ascites and hypalbuminemia. GBWT is a marker for the prediction of esophageal varices. It remains unclear which of these factors is the decisive driver of GBWT. We aim to investigate whether there is a predominant factor associated with the GBWT. Methods We enrolled 258 patients with ascites, hypalbuminemia and/or ACLD and 98 healthy volunteers that underwent abdominal ultrasound. Differences of mean GBWT in subgroups of patients with ACLD, ascites, and/or hypalbuminemia were analyzed. Correlation between various parameters and GBWT were calculated using multiple regression analysis. Results GBWT in patients with ACLD + ascites + hypalbuminemia (n = 59; 5.70 ± 2.05 mm) was pathologically increased compared to patients with hypalbuminemia + ascites without ACLD (n = 36; 2.14 ± 0.66 mm; p < .001) and to patients with only hypalbuminemia (n = 76; 2.02 ± 0.80 mm; p < .001). GBWT of patients with ACLD + hypalbuminemia (n = 30; 3.42 ± 1.52 mm) and with ACLD and normal albumin level were not different (n = 46; 3.10 ± 1.62 mm; p > .999). Significant correlation was seen between GBWT and ACLD (r = .53; p < .001) and ascites (r = .51; p < .001) but not albumin level (r = .04; p = .510). Conclusion We demonstrate that ACLD is predominantly associated with GBWT. In contrast to the current literature, serum albumin level appears not to be associated with pathological GBWT."],["dc.description.abstract","Representative image of a gallbladder of a patient with liver cirrhosis and ascites using a convex transducer (4.0 MHz).

In contrast to guideline recommendations, endoscopic testing for Helicobacter pylori is frequently performed under Helicobacter pylori suppressive conditions, e.g., intake of proton-pump inhibitors (PPI), preceded antibiotic treatment, or recent gastrointestinal bleeding. Our study\\’s aim was to retest patients with—under suppressive conditions—negative test results. This was carried out in order to examine the rate of false negative tests previously gathered under suppressive conditions. Methods. The trial was conducted in a large patient collective in a university hospital. Every elective esophagogastroduodenoscopy from in- and outpatients was included. Prior to endoscopy, suppressive conditions were collected via standardized questionnaire. If Helicobacter pylori testing was indicated, both helicobacter urease test and histology were performed in analogy to the Sydney classification. In case of a negative result under suppressive conditions, the patient was reinvited after, if possible, withdrawal of suppressive condition in order to perform a urea breath test (UBT). Results. 1,216 patients were included (median 59 years, 72.0% inpatients, 28.0% outpatients). Overall, 60.6% (737) were under Helicobacter pylori suppressive conditions. The main suppressive condition was intake of PPIs (54.5%). In 53.7% (653) of all included cases, Helicobacter pylori testing was performed. Of those, 14.1% (92) had a positive test, and 85.9% (561) were negative. Out of the patients with negative result, 50.8% (285) were tested under suppressive conditions and consequently invited for retesting via UBT. In 20.4% (45), suppressive conditions could not be ceased. In 22.8% (65), retesting was conducted. Of those, 98.5% (64) congruently presented a negative result again, and only 1.5% (1) was positive for Helicobacter pylori. Conclusion. Many patients undergoing esophagogastroduodenoscopy in everyday clinical practice are tested for Helicobacter pylori under suppressive conditions leading to a potentially higher risk of false negative results. However, our research shows that this issue might be overestimated."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2022"],["dc.identifier.doi","10.1155/2022/5380001"],["dc.identifier.pii","5380001"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/108523"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-572"],["dc.relation.eissn","2314-6141"],["dc.relation.issn","2314-6133"],["dc.rights","CC BY 4.0"],["dc.title","Systematic Retesting for Helicobacter pylori: The Potential Overestimation of Suppressive Conditions"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
