Objective To investigate the status of familial aggregation of Helicobacter pylori (Hp) infection in Jinniu District, Chengdu, and analyze its risk factors so as to provide a basis for developing prevention and control strategies of family aggregation of Hp infection. Methods A total of 172 subjects in the Second Affiliated Hospital of Chengdu Medical College · 416 Hospital of Nuclear Industry from January 2022 to January 2023 were selected as the research subjects. All subjects underwent 13C-urea breath test (13C-UBT) to diagnose whether there was Hp infection. Analyze the current situation of family aggregation of Hp infection in the region, collect general data of survey subjects, analyze the relevant factors affecting Hp family aggregation infection, and develop prevention and control strategies based on this. Results A total of 242 people from 97 households were surveyed, and the Hp family aggregation rate was 29.33%. Univariate analysis showed that there were statistically significant differences in family aggregation of Hp infection in terms of different age groups (χ2=9.719, P=0.008), marital status (χ2=8.496, P=0.014), occupations (χ2=19.462, P2=5.457, P=0.019), previous Hp test results (χ2 =4.131, P=0.042) and test results after treatment (χ2=12.000, P=0.001), with statistical significance (P<0.05). Multivariate logistic regression analysis showed that the frequency of dining out 2 days or more per week and a positive Hp test results in the past were risk factors for family aggregation of Hp infection, while the occupation of teachers/medical staff/management/technology personnel and a negative Hp results after treatment were protective factors (P<0.05). Conclusion Family aggregation of Hp infection is related to family members' occupation, frequency of dining out, previous Hp test results and Hp test results after eradication, which deserves attention in clinical practice.

Objective To study the changes in serum homocysteine (Hcy) and matrix metalloproteinase-9 (MMP-9) levels and risk factors in patients with coronary heart disease (CHD) complicated with Helicobacter pylori (HP) infection in Chengdu area, and to provide a theoretical basis for the prevention of HP infection in patients with coronary heart disease. Methods A total of 348 CHD patients admitted to our hospital in Chengdu from 2019 to 2021 were selected. Hp infection status was detected by C14 urea breath test. Patients were classified into control group (n=197) and HP infection group (n=151) according to the detection results. Data including gender, age, body mass index and peptic ulcer history were collected, and univariate analysis and logistic regression were used to screen the risk factors affecting the occurrence of HP infection in patients with CHD. Results The prevalence rate of HP infection was 43.39% (151/348) among the selected CHD patients. Serum levels of Hcy and MMP-9 were notably elevated in HP infection group compared with control group (P<0.05). The proportion of patients with age ≥60 years old, hyperlipidemia, proton pump inhibitor use history, and frequent consumption of out-of-home food and spicy food in HP infection group was obviously larger than that in control group (P<0.05). Hyperlipidemia (OR=3.719), history of proton pump inhibitor use (OR=3.254) and frequent consumption of out-of-home food (OR=2.721) were independent risk factors for HP infection in CHD patients (P<0.05). Conclusion CHD patients in Chengdu suffer a prevalence rate of HP infection, and have elevated levels of serum Hcy and MMP-9. Furthermore, the intervention measures for patients with hyperlipidemia, proton pump inhibitor drug use history and frequent consumption of out-of-home food are of vital importance for decreasing the risk of HP infection.

Objective To investigate the correlation of glucose and blood lipid metabolism in elderly patients with Helicobacter pylori (Hp) infection complicated with metabolic syndrome (MS), and to provide theoretical basis for clinical diagnosis and treatment of MS patients. Methods A total of 176 elderly MS patients treated in our hospital from February 2020 to February 2021 were selected. Uremic [13C] tablet breath test kit was used to determine Hp infection. According to Hp infection, they were divided into Hp positive group (n=59) and Hp negative group (n=117). Glucose metabolism indexes (FBG, 2hPG, HbA1c, FINS) and serum lipid metabolism indexes (TC, HDL-C, LDL-C) were determined in all subjects. Risk factors of Hp infection in MS patients were analyzed by multivariate logistic regression. Pearson correlation analysis was conducted between sreum LDL-C, HbA1c and FINS levels and DOB value in MS patients. Results The levels of FBG, 2hPG, HbA1c, FINS and LDL-C in Hp positive group were significantly higher than those in Hp negative group (P0.05). It showed that LDL-C, HbA1c and FINS were independent risk factors for Hp infection in MS patients (P<0.05). Pearson correlation analysis showed that There was a positive correlation between DOB and LDL-C, HbA1c and FINS levels in MS patients (r=0.475,0.512,0.459,P<0.05). Conclusion Hp infection can affect glucose and lipid metabolism in elderly MS patients, and there is a close relationship between Hp infection and ldL-C, HbA1c and FINS levels in elderly MS patients.

Objective To analyze the risk factors of bleeding in elderly patients with peptic ulcer disease (PUD) and its correlation with Helicobacter pylori (Hp) infection, and to provide a theoretical basis for clinical diagnosis and treatment of elderly patients with PUD bleeding. Methods A total of 418 elderly PUD patients admitted to our hospital from June 2019 to June 2020 were selected. The 13C-urea breath test was used to determine HP infection. PUD patients were divided into observation group (n=87, bleeding) and control group (n=331, no bleeding). Age, sex, ulcer number, ulcer location, ulcer stage, ulcer diameter and other clinical data were collected. Univariate analysis and logistic regression were used to analyze the risk factors of bleeding in elderly PUD patients. The Forrest classification was used to evaluate the severity of PUD bleeding patients. Pearson correlation analysis was performed between Forrest classification and Hp infection in elderly PUD bleeding patients. Results There were statistically significant differences between the two groups in the course of disease, PUD history, NSAIDs application/ulcer number, ulcer diameter, ulcer location, ulcer stage, Hp infection and NSAIDs application (P<0.05). Multivariate logistic regression analysis showed that the use of NSAIDs, active ulcer, Hp infection and ulcer diameter ≥2 cm were risk factors for bleeding in elderly patients with PUD (P<0.05). The Hp positive rate in Forrest I patients was significantly higher than that in Forrest II and Forrest III patients (P<0.05). The positive rate of Hp in Forrest II patients was significantly higher than that in Forrest III patients. Pearson correlation analysis showed that Hp infection was positively correlated with the severity of peptic ulcer bleeding in the elderly (r=0.512, P<0.05). Conclusion The risk of bleeding from PUD is higher in the elderly, especially in patients with active ulcer, Hp infection and ulcer diameter ≥ 2 cm. In the treatment process of PUD patients, the eradication therapy of Hp should be emphasized, which can reduce the risk of bleeding.

Objective:To analyze the endoscopic characteristics of early gastric cancer and precancerous lesions after Helicobacter pylori ( H. pylori) eradication. Methods:From May 2019 to June 2022, at Shanghai Sixth People′s Hospital affiliated to Shanghai Jiaotong University School of Medicine, the medical data of patients diagnosed with differentiated early gastric cancer and precancerous lesions were collected. A total of 93 patients with early gastric cancer and precancerous lesions who had previous history of H. pylori infection and had undergone standardized eradication treatment were selected, and their endoscopic characteristics were retrospectively analyzed. Independent sample t-test, chi-square test, and Fisher′s exact test were used for statistical analysis. Results:Among 93 patients with early gastric cancer and precancerous lesions after H. pylori eradication, there were 56 males and 37 females, with an average age of (66.9±8.2) years old. The time after H. pylori eradication was 3.4 years (range 1.0 to 7.0 years). A total of 109 early gastric cancer and precancerous lesions were found, including 79 patients with single lesion and 14 patients with multiple lesions (30 lesions). There were 60 cases with 73 lesions in the early gastric cancer group and 33 cases with 36 lesions in the precancerous group. Among 93 patients, 89 cases (95.7%) were diagnosed with atrophy level above C-2 according to Kimura-Takemoto classification under endoscopy. The long diameter of 109 lesions was (1.38±0.70) cm and the short diameter was (1.04±0.53) cm. A total of 80 lesions (73.4%) were located in the lower 1/3 part of the stomach, and 53 lesions (48.6%) were located in the lesser curvature. A total of 106 lesions (97.2%) were superficial type (0-Ⅱ) under the endoscopy. The long diameter and short diameter in the early gastric cancer group after H. pylori eradication were both greater than those in the precancerous lesion group ((1.54±0.78) cm vs. (1.06±0.35) cm, (1.16±0.58) cm vs. (0.78±0.33) cm), and the differences were statistically significant ( t=3.53 and 3.73, both P<0.001). There was statistically significant difference in the morphological types between early gastric cancer group after H. pylori eradication and precancerous lesion group ( χ2=11.01, P=0.012). The main morphological type of early gastric cancer after H. pylori eradication was superficial depression type (0-Ⅱc), accounting for 45.2% (33/73), while the precancerous lesions were mainly superficial protruded and flat type, both accounting for 38.9% (14/36). Conclusions:After H. pylori eradication, the endoscopic atrophy range of early gastric cancer and precancerous lesions is mostly above C-2. And the lesions are mostly located in the middle and lower 1/3 part of the stomach, long diameter of lesions <20 mm. The main morphological type is superficial type, especially superficial depression type.

Objective:To investigate the expression and clinical significance of vitamin D receptor (VDR) and human β-defensin-2(HBD2) in children with Helicobacter pylori (Hp) infection and gastritis.Methods:Eighty-one children who were hospitalized in the Department of Gastroenterology at Beijing Children′s Hospital from January 2021 to June 2023 and underwent endoscopic examination were collected.They were divided into Hp infection group and non-Hp infection group according to whether they were infected with Hp.The expression levels of VDR and HBD2 between two groups, and the correlation between VDR, HBD2 expression levels and gastritis were compared and analyzed.Results:Among 81 cases, 48 cases were Hp positive, including 24 males and 24 females, with an average age of (11.4±2.7) years; 33 cases were Hp negative, including 14 males and 19 females, with an average age of (11.3±2.6) years.There were no significant differences in sex and age between two groups ( P>0.05). The positive rates of VDR and HBD2 expression in gastric mucosa of children with Hp infection were higher than those of children without Hp infection, and the differences were statistically significant (87.5% vs.39.4%, 79.2% vs.63.6%, all P<0.05). The expressions of VDR and HBD2 had no correlation with age and sex ( P>0.05). The expressions of VDR and HBD2 were positively correlated with granular degeneration of gastric mucosa ( r=0.384, P<0.001; r=0.258, P=0.020). The expression of VDR was positively correlated with the degree of gastric inflammation ( r=0.365, P=0.001), while the expression of HBD2 was not correlated with the degree of gastric inflammation ( P>0.05). Conclusion:The expression levels of VDR and HBD2 in gastric mucosa of children infected with Hp are increased.The expression level of VDR is correlated with the degree of gastritis and the granular degeneration of gastric mucosa.The expression level of HBD2 is correlated with the granular degeneration of gastric mucosa.But there is no correlation between the level of HBD2 expression and the degree of gastritis.
摘要
Introduction: Helicobacter pylori infection is a chronic bacterial infection associated with some extragastric diseases as well as gastric involvements that occur most commonly worldwide. In our study, we aimed to investigate the usability of immature granulocytes as a basic indicator that can reflect the severity of helicobacter pylori inflammation, to the best of our knowledge, for the first time. Materials and Methods: Patients who underwent upper gastrointestinal endoscopy between April 2019 and April 2020 and were diagnosed with antral gastritis were included in this study. The relationship between helicobacter infection and its severity detected in gastric biopsies of patients and immature granulocyte count (IGC), immature granulocyte percentage (IG%), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and mean platelet volume (MPV) were investigated. Results: Of the 868 patients, 210 were HP negative, 658 were HP positive (218 mild HP positive, 293 moderate HP positive, and 147 severe HP positive). There were statistically significant differences between the HP negative and HP positive groups in terms of IGC, IG%, NLR, and PLR. However, IG% and IGC were not clinically useful because the median IG% (0.3 vs 0.3) and IGC (0.02 vs 0.02) were the same in the HP negative and total HP positive groups. Conclusion: In our study, IGC and IG% were not found useful to detect H. pylori intensity and severity of inflammation.

Objective:To investigate the prevalence of carotid artery plaque (CP) in the population undergoing health examinations and to assess the association between CP and Helicobacter pylori (Hp) infection.Methods:The subjects were 3066 patients who underwent carotid ultrasonography examination and 13C urea breath test (UBT) at the health examination center of China-Japan friendship hospital from January 2019 to December 2019. The subjects were divided into CP and non-CP groups; the differences of physicochemical parameters and UBT positive rate between the two groups were analyzed by independent sample t test, Mann-Whitney U test, and Chi-squared test. The association between UBT positive and CP was analyzed by logistic regression. Results:The proportion of CP positive subjects was significantly higher in males than in females (33.4% vs 19.5%, P<0.001); the proportion of Hp positive subjects was not significant in sex composition (29.1% vs 30.9%, P=0.245); the age [(59.39±10.24) vs (46.44±9.88) years], P<0.01), BMI [(25.44±3.23) vs (24.21±3.54) kg/m 2, P<0.01], SBP [(135.91±19.07) vs (123.03±16.66) mmHg, P<0.01], DBP [(79.64±11.47) vs (75.10±11.55) mmHg, P<0.01], TC [(4.96±0.98) vs (4.86±0.98) mmol/L, P=0.004], TG [1.43 (1.03, 2.06) vs 1.20 (0.82,1.88) mmol/L, P<0.001], LDL-c [(3.21±0.93) vs (3.04±0.83) mmol/L, P<0.01)], FBG [5.55 (5.11,6.47) vs 5.16 (4.83,5.56) mmol/L, P<0.001], UA [(339.13±79.92) vs (319.85±87.62) mmol/L, P<0.01] and Hcy [13.10 (11.30,15.60) vs 11.7 (10.00,13.90) mmol/L, P<0.001] were significantly higher in the CP group than that in the non-CP group; HDL-c was significantly lower in the CP group than in the non-CP group [1.12 (0.95,1.32) vs 1.20 (1.00,1.43) mmol/L, P<0.001]. The proportion of male (62.4% vs 44.6%, P<0.01), prevalence of tobacco smoking (31.9% vs 19.6%, P<0.01), hypertension (33.8% vs 12.5%, P<0.01), and diabetes (13.45% vs 3.5%, P<0.01) were significantly higher in the CP group than that in the non-CP group. The proportion of UBT positive subjects was significantly higher in the CP group than in the non-CP group (34.5% vs 28.4%, P=0.001). Logistic regression analysis showed a significantly positive association between CP and UBT positive after adjusted confounding factors ( OR=1.270, P=0.028). Conclusions:The formation of CP is related to many risk factors; Hp infection is also an important risk factor. Controlling Hp infections might be one of the effective methods for the prevention and control of carotid plaque formation.

Objective To investigate status of helicobacter pylori (Hp) infection in Nantong Area and its related factors. Methods A cluster of 1 680 people who underwent a physical examination at a hospital in the Nantong area from June 2020 to February 2021 were selected as the subjects of this survey. All subjects were tested for Hp infection through the 14C-urea breath test and the Hp infection status analyzed. At the same time, the self-filled and interrogative questionnaires made by our hospital were used to collect general data of the research subjects, and then single-factor and multi-factor logistic regression was used to analyze the related factors affecting Hp infection in the physical examination population in Nantong area. Results Among the 1 680 medical examiners investigated in this study, 980 were positive for Hp infection, and the overall positive rate of infection was 58.33%. The results of univariate analysis found that Hp infection was related to the age, drinking, hotness, frequent eating of pickled food, family history of gastric cancer, and chronic gastritis in the physical examination population in Nantong area (P60 years old (OR=3.46, 95%CI: 1.35-8.84), drinking (OR=5.22, 95%CI: 2.79-9.77), addiction to spicy food (OR=5.47, 95%CI: 2.45-9.30), regular consumption of pickled foods (OR=5.28, 95%CI: 3.48-7.92), family history of gastric cancer (OR=4.29, 95%CI: 2.86-76.45), chronic gastritis (OR=5.07, 95%CI: 2.79-9.22) were all related factors affecting Hp infection(P<0.05). Conclusion Positive rate of HP infection in physical examination population in Nantong area is high, and it is related to age, drinking alcohol, spicy food, eating pickled food frequently, family history of gastric cancer, chronic gastritis and other factors. To strengthen the publicity and education of HP infection, establish good eating habits and reduce the risk factors to prevent HP infection in physical examination population in Nantong area.

Objective The aim of the present study was to investigate the relationship between the intake of salt and salted food and the infection of Helicobacter pylori (Hp) among 40-69 years old local residents in a county with high gastric cancer risk in Anhui province. Methods From July 2015 to August 2018, we conducted a questionnaire and a serological test for Hp among 40-69 years old local residents in Lujiang county, Anhui province. The questionnaire focused on the consumptions of salt and salted food. The relationship between Hp infection and risk factors was analyzed by gender. Univariate and multivariate logistic regression analysis were used to analyze the relevant influencing factors. Results The Hp infection rate of total local residents was 50.07%. Among male subjects, age, body mass index(BMI), marital status, educational level, job, labor intensity and income had no link to Hp infection (all P>0.05). But among female subjects, BMI was associated with Hp infection ( 2=13.454,P=0.001). Besides, alcohol consumption was a risk factor for Hp infection in male subjects(OR=1.789，95% CI:1.188-2.694，P=0.003). But, high intake of salt and salted food had no effect on Hp infection after adjustment for alcohol consumption variable in men using multivariate analysis (all P>0.05). After adjusted for BMI variable among female individuals, high salt intake (≥9 g/day) (OR=1.462，95% CI:1.060-2.015，P=0.021) and the high salted food intake (≥1 times /day) were risk factors for Hp infection in women(OR=1.560，95% CI:1.021-2.383，P=0.040). Conclusions In one county with high gastric cancer risk in Anhui province, high salt intake (≥9 g/day) and high salted food intake (≥1 times/day) are risk factors for Hp infection among 40-69 years old female local residents.
摘要
Here we used a meta-analysis of several clinical trials to determine whether anti-Helicobacter pylori therapy has any positive effect on IBS patients. Here we compared the effective clinical remission rates between IBS patients treated with anti-H. pylori therapy and those who were not. This data would provide more clinical evidence regarding the efficacy of novel treatments and intervention points for IBS patients. Relevant studies were identified using keyword searches on various electronic databases, including PubMed, Embase, the Cochrane Central Register of Controlled Trials, CNKI, and CBM. Keywords included "helicobacter pylori" and "irritable bowel syndrome" among others. The literature was screened using relatively strict inclusion and exclusion criteria and RevMan 5.3.5 and Stata 15.1 software were used for meta-analysis and to assess publication bias and sensitivity. A total of ten studies met all of the inclusion criteria; these included 655 IBS patients with H. pylori infection, of these, 385 patients were in the experimental group and 270 patients were in the control group. A random-effects model was used to pool the odds ratios (ORs) with a 95% confidence interval (CIs) and the combined OR was 2.87 (95% CI: 1.74-4.72), p<0.0001. These findings suggest that anti-H. pylori therapy can effectively improve the remission rates of H. pylori-positive IBS patients. H. pylori infection is known to correlate with the incidence of IBS. Anti-H. pylori treatment can effectively improve the clinical remission rates of IBS patients. Whether this means that IBS patients should be actively treated with anti-H. pylori compounds as a novel strategy to improve the remission rates needs to be evaluated in vivo.

摘要
Background: Helicobacter pylori are the primary cause of peptic ulcer disease and an etiologic agent in the development of gastric cancer. The emergence of multi-drug resistant phenotypes is a major public health problem today in the treatment of Helicobacter pylori infection. The present study was designed to evaluate the anti-Helicobacter activities of six Cameroonian medicinal plants on ten Helicobacter pylori clinical isolate from dyspeptic patients and their ability to potentiate the effect of common antibiotics against multidrug-resistance phenotypes Helicobacter pylori. Methodology: Broth microdilution assay was used for the antimicrobial evaluation of plant-extracts alone or in combination with antibiotics, while Time-kill assay was used to study the bactericidal activity. Results: Plant-extracts showed different anti-Helicobacter activity with the minimum inhibitory concentration (MIC) values varying from 64 to >1024 µg/ml. The methanol extract of E. cocaine leaves showed the best anti-Helicobacter activity with MIC value of 64 µg/ml against 60% of the tested isolate. Moreover, E. cocaine extract at a concentration equal to 8MIC, produced from 24 to 72 h a viability decrease of 2 logs lower than those for the control against the tested clinical isolates. Synergistic concentration dependent effects were observed when combining this plant extract with erythromycin, or amoxicillin against Helicobacter pylori multi-drug resistant phenotypes with minimum fold inhibition of 16 and eight respectively for erythromycin and amoxicillin. Conclusion: The overall results provide information for the possible use of E. cocaine extract in the control of Helicobacter pylori infections involving multi-drug resistant phenotypes.
摘要
To identify the Helicobacter pylori antigens operating during early infection in sera from infected infants using proteomics and immunoblot analysis. Two-dimensional (2D) large and small gel electrophoresis was performed using H. pylori strain 51. We performed 2D immunoglobulin G (IgG), immunoglobulin A (IgA), and immunoglobulin M (IgM) antibody immunoblotting using small gels on sera collected at the Gyeongsang National University Hospital from 4–11-month-old infants confirmed with H. pylori infection by pre-embedding immunoelectron microscopy. Immunoblot spots appearing to represent early infection markers in infant sera were compared to those of the large 2D gel for H. pylori strain 51. Corresponding spots were analyzed by matrix-assisted laser desorption/ionization time of flight-mass spectrometry (MALDI-TOF-MS). The peptide fingerprints obtained were searched in the National Center for Biotechnology Information (NCBI) database. Eight infant patients were confirmed with H. pylori infection based on urease tests, histopathologic examinations, and pre-embedding immunoelectron microscopy. One infant showed a 2D IgM immunoblot pattern that seemed to represent early infection. Immunoblot spots were compared with those from whole-cell extracts of H. pylori strain 51 and 18 spots were excised, digested in gel, and analyzed by MALDI-TOF-MS. Of the 10 peptide fingerprints obtained, the H. pylori proteins flagellin A (FlaA), urease β subunit (UreB), pyruvate ferredoxin oxidoreductase (POR), and translation elongation factor Ts (EF-Ts) were identified and appeared to be active during the early infection periods. These results might aid identification of serological markers for the serodiagnosis of early H. pylori infection in infants.

Objective To discuss the application of combined probiotics pretreatment and late triple therapy with helicobacter pylori infection in children.Methods 300 children with helicobacter pylori infection were randomly divided into three groups according to the way of random table.Group A was treated with standard triple therapy, omeprazole,amoxicillin and clarithromycin treatment,and 10 d was 1 treatment course.B group was given probiotic pretreatment,prior to the triple therapy using compound lactobacillus acidophilus piece 1 piece /time,cold water to take after meals,taking 2 weeks,follow -up treatment with triple therapy for 10d.In group C,triple therapy before using compound lactobacillus acidophilus piece 1 piece /time,cold water to take after meals,taking 2 weeks,follow -up treatment with triple therapy for 10d.To take one week after the completion of compound lactobacillus acidophilus piece 1 piece /time,cold water after meals.The clinical therapeutic effects were recorded.Results The helicobacter pylori clearance rate of group A was 55.00%,that of group B was 86.00%,that in group C was 89.00%,the helico-bacter pylori clearance rate of group B and group C was significantly higher than that in group A,the difference was statistically significant (χ2 =23.103 7,28.670 6,all P 0.05 ).In A group,nausea and vomiting occurred in 5 cases,2 cases of diarrhea,abdominal distension abdominal pain in 4 cases,skin rash in 5 cases.In group B,nausea and vomiting occurred in 2 cases,0 cases of diarrhea,abdominal distension abdominal pain in 1 case,skin rash in 1 case.In group C,nausea and vomiting occurred in 1 case,0 cases of diarrhea,abdominal distension abdominal pain 0 cases,skin rashes in 1 case.The incidence rate of adverse reactions in group B and group C was lower than that in group A,the difference was statistically significant (χ2 =11.965 8,8.000 0,all P 0.05). Conclusion Joint probiotics pretreatment and late triple therapy application in helicobacter pylori in children can promote helicobacter pylori clearance,reduce the triple therapy drug adverse reactions,it is worthy of popularization and application in clinic.
摘要
Migraine is a primary episodic headache disorder that represents a substantial burden and disability worldwide. Its pathogenesis is multifactorial and remains hitherto poorly elucidated. An interesting but less-well-known association is that between migraine and gastrointestinal disorders. We have reviewed the literature for relevant papers reporting on the clinical association between migraine and gastrointestinal symptoms. Several studies have shown different gastrointestinal diseases to be associated with migraine, but the underlining pathophysiology remains elusive. The data gathered and analyzed have shown great variability across studies, making it impossible to draw definitive conclusions. Further research is required to elucidate this potential relationship. An understanding of the relationship between migraine and gastrointestinal disorders is of great clinical importance for prompt diagnosis and treatment.

Upper gastrointestinal bleeding (UGB) has important morbidity and mortality risk and these risk increases when co-morbidities exist. Nonsteroidal anti-inflammatory drugs use and Helicobacter Pylori infection are risk factors for peptic ulcer bleeding. Peptic ulcer disease is the most common cause of non variceal UGB. However, other rare causes should be responsible for UGB especially in treatment resistant cases.
