Abstract:
Background: Helicobacter pylori (Hp) is classified by the International Agency for Research on Cancer (IARC) as a Group 1 carcinogen. Its influence on the carcinogenesis of gastric cancer has been confirmed in many researches. The conclusion is obvious- early detection and eradication of Hp can prevent the development of the disease. Methods: The objective of the study was to analyse the clinical and practical value of Carbon-13 urea breath test (UBT) in patients hospitalized due to pain complaints in the upper abdomen and dyspeptic symptoms. Fifty patients were enrolled in the study. Each patient underwent urea breath test according to the instruction included by the producer. Thereafter, each patient included in the study group was performed endoscopy of the upper gastrointestinal tract with the biopsy of the mucosa to determine the urease activity with rapid urease test (RUT). Results: In the study group, 14 patients (28%) achieved a positive urease test result which was confirmed in RUT. Four (8%) patients, despite a positive breath test, did not have a positive result in urease activity from gastric mucosa. In 2 cases (4%) despite negative result of UBT there was urease actitvity confirmed in gastroscopic sections. The remaining 30 patients (60%) had a negative result in both studies. Conclusions: The limited availability of the gold standard for diagnostics of upper gastrointestinal tract diseases (gastroscopy) is the basis for the search for new methods for the detection of Helicobacter pylori infection. The urea breath test is a method of high sensitivity and specificity. The positive result of urea breath test may be the basis for the inclusion of eradication therapy.

Abstract:
Introduction. Helicobacter pylori is a bacterium that has been in the limelight of gastroenterologists and oncologists worldwide since its immediate effect on the development of gastritis, ulcer disease, mucosa-associated lymphoid tissue lymphoma and gastric cancer was proved. The aim of this study was to determine the correlation between the positive immunological test, rapid urease test and pathohistological finding in detecting Helicobacter pylori infection of the gastric mucosa. Material and Methods. This retrospective study included 250 endoscopic findings of subjects having undergone endoscopy in the first half of 2010 at the Ward of Gastroenterology, Department of Internal Diseases, Hospital in Senta. The endoscopy procedure was performed by Fujinon endoscopes and the fast urease test was done by the Cambridge Life Science set from England. The immunological test was carried out by the Vidas apparatus applying the Enzyme-Linked Fluorescent Assay (ELFA) technique and the staining for the pathohistological analysis was done by the modified Giemsa method. Results. The paper presents the results obtained by endoscopic examination of a group of 250 patients performed at the Ward of Gastroenterology, Department of Internal Diseases, Hospital in Senta. The endoscopic findings were the first to be analyzed then the rapid urease test findings, which showed that 95 (38%) patients were positive and 155 (62%) patients were negative; whereas the immunologic test for Helicobacter pylori was positive in all 250 patients (100%). The histological test for Helicobacter-Like Organism was positive in 105 subjects (42%), whereas it was negative in 145 patients, that being 58% of all the cases. Sensitivity, specificity and predictability of the serological test and the rapid urease test were calculated according to the pathohistological finding as the ?gold standard? and they were found to be: sensitivity 100% and specificity 0% for the serological test and sensitivity 90% and specificity 100% for the rapid urease test. The immunologic test was not correlated with other findings, and there was a high level of correlation between the rapid urease test and histological test (r=0.927589261). The t-test was calculated to be 36.16513; p=0.0001; that indicating that the correlation coefficient was statistically significant (p>0.01). Discussion. The obtained results were compared with the data found in the available literature sources. Conclusion. It can be concluded that the most competent technique for the optimal diagnosis of Helicobacter pylori infection is the invasive one with the pathohistological examination of bioptates together with the rapid urease test.

Abstract:
The article discusses the problems of diagnosing Helicobacter pylori (H.pylori) using a rapid urease test (RUT). Features of H.pylori colonization and persistence are highlighted, which affect the results of RUT and determine the preferential use of biopsy specimens for the study, rather than gastric mucus aspirate, the localization of biopsy collection and their optimal number and the factors influencing the urease activity of H.pylori are indicated. Based on the described properties, the main causes of erroneous results and methods for preventing false negative and false positive results are given, the basic rules for working with RUT are formulated to obtain optimal results.

Abstract:
A prospective study was conducted to assess the sensitivity and specificity of diagnostic tests for Campylobacter pylori in 60 unselected patients referred for gastroscopy. Urease testing was performed on samples of gastric mucus obtained by a disposable cytology brush and on gastric mucosal biopsies. The combination of the brush urease test and biopsy urease test had a sensitivity of 78% and a specificity of 96%. The combination of the brush urease test and examination of gastric biopsies for curved bacilli had a sensitivity of 96% and a specificity of 96%. The combination of the brush urease and biopsy urease tests will rapidly identify the majority of patients withC pylori. This test is rapid, easy, sensitive and inexpensive. If a pathologist is available, the addition of histologic review forC pyloriin combination with the brush urease test, will identify virtually all patients withC pyloriwithout the need for culturing this fastidious organism.

Abstract:
CONTEXT: Multiple diagnostic methods are available for the detection of Helicobacter pylori infection, but at present no single one can be used as the gold standard. OBJECTIVE: The aim of this study was to evaluate the diagnostic accuracy of 3 invasive and 2 non-invasive methods for detection of Helicobacter pylori infection in symptomatic children and adolescents. DESIGN: Prospective cohort study SETTING: Peptic Disease outpatients service, Discipline of Pediatric Gastroenterology, Universidade Federal de São Paulo / Escola Paulista de Medicina. PATIENTS: Forty-seven patients who underwent endoscopy because of dyspeptic symptoms. DIAGNOSTIC METHODS: Endoscopy with gastric biopsies for 3 invasive (rapid urease test, histology and culture) and 2 non-invasive methods (a commercial ELISA serology and 13carbon urea breath test - isotope ratio mass spectrometry) for detection of Helicobacter pylori infection. MAIN MEASUREMENTS: Sensitivity, specificity, positive and negative predictive values of each method and agreement and disagreement rates between the methods. RESULTS: Forty-seven patients [mean age, 11y9mo (SD 2y10mo), 27 female and 20 male]; 62% of them were Helicobacter pylori-positive. All methods agreed in 61%, and were negative in 21% and positive in 40%. The greatest concordance between 2 methods occurred between the invasive methods: histology and rapid urease test (89.6%) and histology and culture (87.5%). The greatest sensitivity, considering Helicobacter pylori-positive cases, for any combination of 3 or more tests, was achieved by the rapid urease test (S=100%), followed by histology, serology and 13carbon-urea breath test (S=93.1%) and lastly by culture (S=79.3%). The highest specificity was obtained by histology (100%) and culture (100%), followed by the rapid urease test (84.2%), serology (78.9%) and 13carbon-urea breath test (78.9%). CONCLUSIONS: Our results suggest that among invasive methods, an association between the rapid urease test and histology constituted the best choice for the detection of Helicobacter pylori infection. If results of histology and the rapid urease test are different, serology may be recommended.

Abstract:
The issues of optimizing the management of patients infected with Helicobacter pylori have remained relevant in clinical therapy and gastroenterology for many years. This is due both to the high prevalence of H. pylori infection in Russia: depending on the region, it is 35–60 %, and to the potential carcinogenicity of the microorganism in relation to the development of gastric cancer. According to clinical recommendations, when conducting an endoscopic examination of the upper gastrointestinal tract, a rapid urease test with biopsy samples from the antrum and body of the stomach or histological examination of biopsies of the gastric mucosa may be recommended as a method of primary diagnosis of infection, and a 13C-urease breath test or determination of the antigen of a microorganism in feces is recommended as a non-invasive diagnostic. The use of rapid urease tests with selectivity for H. pylori, which do not respond to pH changes and to the urease of other urease producents. For non-invasive diagnostics, alternative ways of verifying the microbe can also be considered, for example, an ammonium breath test, when the level of CO2 in the exhaled air is not determined, but the second metabolite of urea hydrolysis – ammonia.

Quality control of endoscope processing is carried out in accordance with the requirements of the current sanitary legislation (1,2) within the framework of industrial control by instrumental and laboratory methods. The results of instrumental control entirely depend on the quality of the final cleaning of the endoscope by hand. The results of laboratory control are determined not only by the efficiency of the entire processing cycle, but also by the correctness of sampling and delivery to the microbiological laboratory. Interpretation of unsatisfactory results of microbiological control is very important. It includes searching for technical malfunctions, biological films and system errors in processing, if there are indications for this.

Abstract:
CONTEXT: The correct diagnosis and effective treatment of Helicobacter pylori gastric infection are essential in controlling this infection. OBJECTIVE: To compare the diagnostic value of three tests based in endoscopic gastric biopsies histopathological evaluation with hematoxylin-eosin (H-E) staining, urease rapid test and microbiological culture for detecting Helicobacter pylori active infection, in order to make recommendations for daily clinical practice. METHODS: Gastric biopsies from 115 adult patients (85 female/30 male) were obtained by upper gastrointestinal endoscopy and studied by histopathological evaluation with H-E (antrum-corpus), urease test in 2 hours (antrum) and microbiological culture (antrum). RESULTS: Helicobacter pylori active infection was diagnosed in 67% of patients. Helicobacter pylori active infection was detected by histopathological evaluation with H-E, urease test and microbiological culture in 87%, 79% and 70% of the positive cases, respectively. There were significant differences when histopathological evaluation with H-E and urease test rapid test when compared with microbiological test (P&lt;0.01). There was no significant difference between histopathological evaluation with H-E and urease test (P = 0.7). The kappa index of agreement for histopathological evaluation with H-E/urease test was 0.56, histopathological evaluation with H-E/microbiological culture 0.6, and urease test/microbiological culture 0.64. CONCLUSIONS: In a hospital setting like the one studied, histopathological evaluation with H-E and urease test are the most recommended tests for diagnosis of Helicobacter pylori active infection based in endoscopic biopsies. If pathological information of gastric lesions will be required, histopathological evaluation with H-E is essential. Urease test is mandatory if a prompt diagnosis is necessary. Microbiological culture can be used in cases of persistent or complicated infection, which may require studies on Helicobacter virulence or antimicrobial susceptibility. Selected cases might demand a combination of several tests. The three tests exhibit a good concordance level for Helicobacter pylori active infection diagnosis.

Abstract:
The purpose of the study was to identify and evaluate the practical value of the most common diagnostic methods for Helicobacter pylori infection in patients with chronic inflammation of the gastric mucosa.&#x0D; Materials and methods. The study involved 104 people. All the patients examined underwent esophagogastroduodenoscopy with a rapid urease histochemical test for Helicobacter pylori and a standard five-point biopsy of the gastric mucosa for morphological evaluation and bacterioscopy. If the result of the quick urease histochemical test coincided with the data of the biopsy study on Helicobacter pylori, no further examination was carried out. In case of discrepancy the patients additionally underwent the 13C-urease breath test.&#x0D; Results. It was found that the sensitivity of the rapid urease histochemical test in the area of the proposed model, according to our study, was 89.74% and the specificity was 46.15% when validating it using the additional methods. Similar calculations for the diagnostic method of staining by Giemsa showed sensitivity of 100% and specificity of 97.4%. The total number of the infected in the survey was 78 out of 104 people, which amounted to 75%.&#x0D; When analysing the severity of activity, inflammation and atrophic changes in the gastric mucosa, it was found that in the patients with two positive tests, the severity of the processes was significantly higher than in those with one positive test or all the tests were negative (p 0.05). When comparing the same processes in cases where only a quick urease histochemical test was positive and no signs of Helicobacteriosis were detected in any test, no significant differences were detected.&#x0D; Discussion. The rapid urease histochemical test showed good sensitivity of 89.74%, but unsatisfactory specificity of 46.15%, which severely limits its use. An unexpected result for this methodology was a large number of false positive tests, while the European recommendations indicate a more frequent occurrence of false negative results, which can be explained by differences in the production technology of the test systems. High sensitivity and specificity of the Helicobacter pylori test using Giemsa staining strongly depends on observing the methodology and experience of a specialist and cannot be recommended as a standard in the routine medical use.&#x0D; The study confirmed the recommendations for using at least two diagnostic tests to diagnose the infection, while the most common rapid urease histochemical test always needs confirmation. As a result of the analysis, it can be said that esophagastroduodenoscopy with a rapid urease histochemical test for Helicobacter pylori and standard diagnostic biopsy is the optimal method for diagnosing the pathology of the upper sections of the gastrointestinal tract. Moreover, 13C-UDT seems to be almost ideal as a screening technique and for evaluating treatment in cases where endoscopic monitoring is not necessary.

Abstract:
Objective: The study aimed to detect the presence of Helicobacter pylori infection in children using two investigative methods: the rapid urease test and histological methods. It also examined the relationship between socioeconomic status and Helicobacter pylori infection.Design: This was a cross-sectional study conducted in the paediatric theatre at Korle Bu Teaching Hospital in Accra, Ghana.Participants: Children who were scheduled for upper gastrointestinal endoscopy were recruited into the study.Main outcome measures: The presence of Helicobacter pylori in gastric biopsies was measured using a rapid urease test and histology.Results: Seventy-three children aged 2 years to 16 years were seen during the period. Both tests were positive at the same time in 36 (49.3%) out of the 73 children (p&lt;0.0001). The positivity rates for the rapid urease test and histology were 57.5% and 53.4 %, respectively. Significant predictors of the histology presence of H. pylori were a large household size of at least 6 members (AOR: 4.03; p&lt;0.013) and the presence of pets at home (AOR: 3.23; p&lt;0.044).Conclusions: Substantial agreement was found between the rapid urease test and histology examination of gastric biopsies for the presence of H. pylori. Children from large households and those with pets at home appear to have increased odds of having H. pylori infection of the gastric mucosa.

Background: Laryngopharyngeal reflux is retrograde flow of contents of the stomach to the larynx and the pharynx. The study aims to compare two regimens (proton pump inhibitor monotherapy versus triple therapy) on the outcome of Helicobactor pylori positive laryngopharyngeal reflux disease.&#x0D; Methods: The presence of laryngopharyngeal reflux was determined by reflux symptom index and reflux finding score. The presence of Helicobactor pylori in the tissue was confirmed by rapid urease test. All urease test negative laryngopharyngeal reflux patients were given a course of proton pump inhibitors and results were evaluated. All urease test positive patients were divided into two groups. One group was given a course of proton pump inhibitors and another group was given a course of triple therapy and the results were compared.&#x0D; Results: A total number of 704 laryngopharyngeal reflux patients were screened for urease test. Among them 138 patients (19.6 %) were urease test negative and were given proton pump inhibitor therapy. Improvement in both reflux finding score (average score 11.75) and reflux symptom index (average score 5.25) score was observed after 3 months with p-value&lt;0.05. In urease test positive patients, improvement in scores was observed in both proton pump inhibitors and triple therapy group, however marked improvement in the clinical features was observed in triple therapy group with p-value&lt;0.05.&#x0D; Conclusions: The study reveals association between laryngopharyngeal reflux and Helicobactor pylori. Proton pump inhibitor therapy is sufficient if no Helicobactor pylori is detected, however incase of presence of Helicobactor pylori, triple therapy gives better results.&#x0D; Keywords: Helicobacter pylori; laryngopharyngeal reflux disease; rapid urease test

Abstract:
Background: Functional dyspepsia is referred to wide spectrum of upper gastrointestinal symptoms which are nonspecific and without organic pathology of upper gastrointestinal tract, and accounts for &gt;60% of patients undergoing upper gastrointestinal endoscopy. The aim of our study was to determine the prevalence of active Helicobacter pylori (H. pylori) infection by retrospective review of patient records using only rapid urease test reports which gives us the magnitude of the H. pylori prevalence.Methods: 200 patients who presented with dyspepsia were studied clinically according to the proforma over a period of 18 months from April 2020 to October 2021, Patients underwent upper gastro-intestinal endoscopy under topical anesthesia, and biopsies were taken from the antrum. Biopsy specimens were immediately placed onto rapid urease test kit containing urea and an indicator. Positive test for H. pylori was confirmed by the change in color of the medium from yellow to pink or red and when the rapid urease test was positive, patient was considered as H. pylori positive.Results: Out of 200 patients, most commonly affected age group are patients between 18-35years and is more in males than females (48:36), 86 patients were found to be H. pylori positive (43%) associated with acid peptic disease and duodenal ulcers, gastric antral ulcers.Conclusions: H. pylori is a potential risk factor of gastric malignancy. After being aware of the prevalence of H. pylori by early detection of active H. pylori infections, rapid urease test serves only as a rapid screening tool in dyspeptic symptoms of patients with acid peptic disease than all other tests.

Abstract:
Abstract Objective.—To evaluate simultaneous diagnosis of infection and molecular resistance testing of Helicobacter pylori. Methods.—Gastric biopsies were obtained from 26 rapid urease-positive and 51 rapid urease-negative test kits used to diagnose H pylori infection. Following glass bead–assisted DNA isolation, amplification of H pylori 16S ribosomal DNA (rDNA), glmM, and 23S rDNA target genes was performed. Results.—Helicobacter pylori DNA was successfully amplified from 100% (26/26) of urease-positive and 3.9% (2/51) of urease-negative gastric biopsies. Subsequent restriction enzyme–mediated digestion of 23S rDNA amplification products revealed that 17% (4/24) of urease-positive and H pylori DNA–positive biopsy specimens contained point mutations (A2142G or A2143G) associated with clarithromycin resistance. Helicobacter pylori DNA from gastric biopsies was successfully amplified 8 weeks following rapid urease testing. Conclusion.—Helicobacter pylori genotyping may be used to detect macrolide-resistant H pylori in individuals prior to initiation of therapy or in patients refractory to anti-H pylori therapy. Two urease-negative specimens yielded Helicobacter DNA distinct from that of H pylori and indicated the need for further investigations of Helicobacter species present in the human stomach.

Abstract:
Background: Helicobacter pylori is one of the most important infectious agents in the world. These bacteria infect 50% of the world population. Gastritis due to H. Pylori has been associated with the incidence of peptic ulcer, B cell primary lymphoma in the stomach, and gastric carcinoma. In dyspepsia, eradication of H. Pylori helps symptoms improvement and treatment cost efficiency. This study aimed to evaluate urease test in diagnosing H. Pylori infection in dyspepsia patients. It is expected that we could obtain a scientific evidence which can become the basis of routine use of urease examination in diagnosing H. Pylori infection.Method: This study used diagnostic study design. This study was performed in adult dyspepsia patients who underwent endoscopy examination in Gastrointestinal Endoscopy Centre Cipto Mangunkusumo General Hospital in January – November 2018. One biopsy sample was intended for rapid urease test using Helicotec which was performed according to the standard procedure and was interpreted 2 hours later. Biopsy for histopathological examination was preserved in formalin solution and sent to Histopathology Department for analysis and identification of H. Pylori bacteria. Results: Prevalence of H. pylori infection based on histopathology examination was 7.2%. From seven positive results in histopathology examination, four samples were Helocitec positive. The sensitivity and specificity of Helicotec was 57.1% and 98.9%. The positive predictive value and negative predictive value were 80% and 96.7%. Conclusion: Rapid urease examination using Helicotec is one of H. pylori diagnostic tools that is good enough to diagnose faster and cheaper. Interpretation of rapid urease test also need to consider clinical condition of patients who are tested.

Abstract:
Introduction: Helicobacter pylori infection is the most important cause of peptic ulcer disease as well as other gastrointestinal conditions. Most widely used diagnostic tests for detection of Helicobacter pylori include rapid urease test, histopathology, culture/sensitivity and serology. The objective of this study was to determine accuracy of standard diagnostic tests and the prevailing local antibiotic susceptibility patterns. Methods: This cross sectional study, conducted from May to October 2009 at Tribhuvan University Teaching Hospital. 3 pieces of biopsy pieces were obtained from the antral mucosa which were subsequently used for Rapid Urease Test (RUT), histopathology and culture/sensitivity. Then, 2 ml of venous blood was drawn from the antecubital vein for serological examination. Results: H. pylori positivity status was reflected as 32%, 32% and 47% by rapid urease test, culture and histology. The seroprevalence of H. pylori was 63%. A patient was considered to be positive with respect to H. pylori infection when at least two of three tests namely rapid urease test, culture and histology gave positive results. Hence, proportion of patients with positive H. pylori infection was 36%. Only 30 from 32 culture positive cases were efficiently subcultured and further processed for antibiotic susceptibility testing. Resistance to metronidazole was found to be the highest securing 53.3% and lowest to levofloxacin (0%). Conclusions: Detection of Helicobacter pylori infection using serology was the most effective among the diagnostic tests performed. More than half of the patients were resistant metronidazole while levofloxacin was sensitive in all the cases.

Abstract:
Background: Gastritis is one of the commonest clinical conditions encountered by a physician. The most common cause is said to be infection with Helicobacter pylori. The present study was aimed to diagnose the prevalence of H. pylori infection among the cases of gastritis and its correlation with histopathological findings and associated rapid urease test.Methods: A one year prospective study at a tertiary care hospital was conducted and all cases of gastritis were included and socio demographic data, clinical complaints and duration were noted. Endoscopy was performed on all cases. Biopsy was performed histopathological examination with staining and graded by Houston-updated Sydney system. Rapid urease test was performed and findings noted.Results: 325 cases with 215 male and 110 female cases were included. 26.15% were in age group of more than 60 years and number of cases increased with age. Mean age of study participants was 39.12±2.8 years and heart burn was the common complaint in the study cases. 81.54% of the cases revealed endoscopic gastritis on endoscopy and hyperaemia was commonest. 83.69% were positive by rapid urease test. Rapid urease test is more sensitive than histological staining in confirmation of H. pylori infection.Conclusions: To conclude on the present study, the prevalence of H. pylori infection is on a global rise and appropriate measures to reduce the prevalence is quite an urgent necessity. Histopathological interpretation of gastric biopsies is a reliable indicator of H. pylori infection as well as gastritis grading according to the Sydney grading system.

Abstract:
CONTEXT: The development of simple, accurate and low-expense techniques for detection of Helicobacter pylori infection has great relevance. OBJECTIVE: To determine the accuracy of a rapid 14C-urea breath test (UBT) employing a very simple device for breathed air collection. DESIGN: Prospective study. SETTING: Hospital das Clinicas of the Faculty of Medicine of Ribeirão Preto. PARTICIPANTS: One hundred and thirty-seven adult patients who underwent upper gastrointestinal endoscopy in the Clinical Hospital. MAIN MEASUREMENTS: Histology for Helicobacter pylori (HP); urease test; urea breath test (UBT). RESULTS: One hundred and fifteen patients were infected by HP (HP+) according to both histology and the urease test, and 22 patients were HP-negative (HP-), according to the same two tests. UBT was capable of discriminating between HP+ and HP- in a way that was similar to the combination of urease test and histology. When this combination of results is taken as the "gold standard" for HP infection, the sensitivity and specificity of UBT are both greater than 90% for a range of cut-off points and breathed air collection times. CONCLUSION: The rapid UBT employing a simple device for air collection has a high accuracy in determining HP infection.

Abstract:
BACKGROUND: Despite the availability of several methods (invasive and noninvasive) for the diagnosis ofHelicobacter pyloriinfection, no test is considered to be the ‘gold standard’. Endoscopy-based tests are regarded as the reference method in most studies.OBJECTIVE: To evaluate the diagnostic performance of imprint cytology smears of antral biopsies compared with Gram-stained smears, the rapid urease test and culture methods, separately and in combination.METHODS: Antral biopsies were obtained from consecutive patients undergoing upper gastrointestinal endoscopy at a single centre. The biopsies were examined for the presence ofH pyloriby Gram-stained smear, the rapid urease test, culture methods and imprint cytology smear.RESULTS: A total of 273 biopsies were studied. All tests were positive in 36% of the patients. Of 252 biopsies tested, 73% were positive using the imprint cytology technique. Using Gram-stained smear, the rapid urease test and culture methods individually, the sensitivity and specificity of imprint cytology smears for the detection ofH pyloriwere found to be 92.7% and 50%; 92.7% and 49%; and 92.4% and 38.5%, respectively. Combining the three microbiological methods resulted in a sensitivity of 92.1%, a specificity of 51.0% and an efficiency of 71.7% for imprint cytology smears.CONCLUSIONS: Endoscopic examination provides useful clinical information. Imprint gastric cytology can be used as a rapid test to establish the diagnosis ofH pyloriinfection at the time endoscopy is performed, enabling the endoscopist to start treatment with immediate effect.

Abstract:
Introduction: Endoscopic rapid urease test is a simple and most widely used test to detect the presence of urease in the gastric mucosa. Many studies have reported prevalence of H. pylori infection in relation to age, gender and site of ulcer. Therefore, this study was designed to determine the prevalence and significance of H. pylori in peptic ulcer disease. &#x0D; Methods: A retrospective review was carried out for patients with peptic ulcer disease who had undergone upper GI endoscopy in Department of Internal Medicine at Kathmandu Model Hos­pital. The records from January 2013 to December 2017 were analyzed. Any patient with previously diagnosed peptic ulcer, history of active bleeding, cancer and incomplete records were excluded. Peptic ulcer associated with H. pylori was diagnosed on the basis of endoscopic rapid urease test. &#x0D; Results: Among the 418 diagnosed case of peptic ulcer disease by upper GI endoscopy from Jan 2013 to Dec 2017, 213 tested positive for H. pylori by rapid urease test. Among the positive cases, over a half were males patients. Majority (23.9%) of the patients were in the age group of 35-44 years. Prevalence of H. pylori in duodenal ulcer was 51.6% followed by combined gastro-duodenal ulcer (26.8%) and gastric ulcer (21.6%). H. pylori was significantly associated with duodenal ulcer (p&lt;0.0001). &#x0D; Conclusion: This study demonstrated relatively high prevalence of H. pylori infection in patients with duodenal ulcer who had undergone upper GI endoscopy.

Pylori positive cases and follow up endoscopic biopsy at six weeks to confirm eradication and to investigate other factors associated with peptic ulcer perforation.&nbsp;<strong>Materials and Methods:</strong>&nbsp;This study was done as a prospective observational study, in patients who present in surgery casualty undergoing surgery for peptic ulcer perforation for a period of one year in a tertiary care teaching hospital. This study included 100 patients who present in surgery casualty undergoing surgery for peptic ulcer perforation. H. Pylori infection is confirmed by mucosal biopsy at the time of surgery using rapid urease test. H. Pylori eradication regimen is given to positive cases for 14 days. Follow up endoscopy done at 6 weeks and biopsy taken from gastric antrum and rapid urease test performed to confirm eradication.&nbsp;<strong>Results:</strong>&nbsp;The site of perforation was; in gastric antrum in 93% (n=93) of the cases in duodenum in 7% (n=7) of the cases.&nbsp; Out of 100 patients, 63% (n=63) were rapid urease test positive. 37% (n=37) were rapid urease test negative Out of 100 patients, rapid urease test was positive in 63% (N=63) cases. H. Pylori treatment was given for 62 patients out of the 63 cases. One of rapid urease positive patients was not treated with H. Pylori regimen. Out of 62 patients treated for H. Pylori, around 92% (n=57) turned out negative while around 8% (n=5) were positive.&nbsp;<strong>Conclusion:</strong>&nbsp;Routine endoscopic examination of such patients should also form a part of the follow-up to look for ulcer healing postoperatively. There is a change in the trend of the management of peptic ulcer perforation with the advent of newer and less invasive techniques, such as laparoscopic or endoscopic perforation sealing technique. A multidisciplinary approach for perforated peptic ulcer management is of utmost importance and help in early recovery of the patient. &nbsp; &nbsp; &nbsp;

Abstract:
We compared immunohistochemical and silver stains of pediatric gastric biopsy sections for the identification of Helicobacter pylori infection with chronic inflammation and a negative urease screening test. Thirty-seven patients (age range 10 months to 21 years) whose gastric antral biopsies were negative for the rapid urease test (CLOR) but positive for lymphocytic infiltration were selected for a retrospective study. Specimens had been subjected to a rapid urease test (CLOR) and hematoxylin and eosin staining, and Dieterle silver staining and immunohistochemical staining specific for H. pylori were also performed. Twelve additional patients with ureasepositive biopsies were used as controls. With Dieterle staining, 8/37 (22%) urease-negative biopsies contained organisms morphologically compatible with H. pylori, 21/37 (56%) contained organisms not compatible with H. pylori, and 8/37 (22%) were negative for organisms. Immunostaining confirmed 6/8 (75%) Dieterle-positive cases as being H. pylori, was negative in 2/8 (25%) Dieterle-positive cases, and was positive in 2/8 (25%) Dieterle-negative cases. Biopsies from 8/12 (67%) urease-positive specimens contained organisms seen with both Dieterle and immunohistochemical stains, and 4/12 (33%) were negative with both stains. Although both stains yielded comparable results with H. pylori–positive biopsies, Dieterle staining was potentially confusing because of nonspecific staining of other organisms. A significant proportion of (CLOR)-negative biopsies was positive for H. pylori with special stains. We therefore recommend the use of immunohistochemical staining rather than silver staining in the evaluation of urease-negative gastric biopsies demonstrating chronic inflammation in children.

Abstract:
When urease production was assayed by the hydrolysis of [14C]urea, all basidiomycetous yeasts tested, including the Cryptococcus vishniacii complex (previously reported urease negative), produced significant amounts of 14CO2. The Schizosaccharo-mycetaceae were the only urease-positive ascomycetous yeasts tested. Yarrowia lipolytica was urease negative. The stoichiometry of [14C]urea hydrolysis paralleled by Roberts' rapid urea hydrolysis (RUH) test indicated that causes of anomalous results in conventional urease testing include acidification and alkalinization of the test medium by products of endogenous metabolism and autolysis rather than urease activity. Anomalous results also occurred when cells were grown on media containing the chelating agent ethylenediaminetetraacetic acid (EDTA) prior to RUH. The addition of EDTA to a complex natural medium inhibited urease production in all yeasts reportedly growing at 35 °C (and all other yeasts tested), except Filobasidiella (Cr.) neoformans var. neoformans (NIH 12). The RUH test could differentiate at the varietal level: Fil. (Cr.) neoformans var. neoformans was about 10 times more resistant to EDTA in media used for the growth of cells prior to RUH testing than was Fil. neoformans var. bacillispora (Cr. neoformans var. gattii) (NIH 191). Urease production by Fil. neoformans var. bacillispora was specifically restored to half maximal activity by the addition of 22 μM Ni+2 (as NiCl2) to a growth medium containing 0.100 mM EDTA.
