[A case of duodenal ulcer as prominent manifestation of IgG4-related disease]

A case of IgG4-related disease presented with a duodenal ulcer to improve the understan-ding of IgG4-related diseases was reported. A 70-year-old male presented with cutaneous pruritus and abdominal pain for four years and blackened stools for two months. Four years ago, the patient went to hospital for cutaneous pruritus and abdominal pain. Serum IgG4 was 3.09 g/L (reference value 0-1.35 g/L), alanine aminotransferase 554 U/L (reference value 9-40 U/L), aspartate aminotransferase 288 U/L (reference value 5-40 U/L), total bilirubin 54.16 μmol/L (reference value 2-21 μmol/L), and direct bilirubin 29.64 μmol/L (reference value 1.7-8.1 μmol/L) were all elevated. The abdominal CT scan and magnetic resonance cholangiopancreatography indicated pancreatic swelling, common bile duct stenosis, and secondary obstructive dilation of the biliary system. The patient was diagnosed with IgG4-related disease and treated with prednisone at 40 mg daily. As jaundice and abdominal pain improved, prednisone was gradually reduced to medication discontinuation. Two months ago, the patient developed melena, whose blood routine test showed severe anemia, and gastrointestinal bleeding was diagnosed. The patient came to the emergency department of Beijing Hospital with no improvement after treatment in other hospitals. Gastroscopy revealed a 1.5 cm firm duodenal bulb ulcer. After treatment with omeprazole, the fecal occult blood was still positive. The PET-CT examination was performed, and it revealed no abnormality in the metabolic activity of the duodenal wall, and no neoplastic lesions were found. IgG4-related disease was considered, and the patient was admitted to the Department of Rheumatology and Immunology of Beijing Hospital for further diagnosis and treatment. The patient had a right submandibular gland mass resection history and diabetes mellitus. After the patient was admitted to the hospital, the blood test was reevaluated. The serum IgG4 was elevated at 5.44 g/L (reference value 0.03-2.01 g/L). Enhanced CT of the abdomen showed that the pancreas was mild swelling and was abnormally strengthened, with intrahepatic and extrahepatic bile duct dilation and soft tissue around the superior mesenteric vessels. We pathologically reevaluated and stained biopsy specimens of duodenal bulbs for IgG and IgG4. Immunohistochemical staining revealed remarkable infiltration of IgG4-positive plasma cells into duodenal tissue, the number of IgG4-positive cells was 20-30 cells per high-powered field, and the ratio of IgG4/IgG-positive plasma cells was more than 40%. The patient was treated with intravenous methylprednisolone at 40 mg daily dosage and cyclophosphamide, and then the duodenal ulcer was healed. IgG4 related disease is an immune-medicated rare disease characterized by chronic inflammation and fibrosis. It is a systemic disease that affects nearly every anatomic site of the body, usually involving multiple organs and diverse clinical manifestations. The digestive system manifestations of IgG4-related disease are mostly acute pancreatitis and cholangitis and rarely manifest as gastrointestinal ulcers. This case confirms that IgG4-related disease can present as a duodenal ulcer and is one of the rare causes of duodenal ulcers.

Eosinophilic Gastroenteritis-associated Duodenal Ulcer Successfully Treated with Crushed Budesonide

Eosinophilic gastroenteritis (EGE)-associated duodenal ulcer is rare and its endoscopic and pathological features remain poorly described. A 15-year-old boy was referred to our hospital for further examination and treatment of duodenal ulcer. Esophagogastroduodenoscopy (EGD) revealed two A2-stage duodenal ulcers on the duodenal bulb. A biopsy revealed marked infiltration of eosinophils, suggestive of EGE-associated duodenal ulcers. Thus, treatment with crushed budesonide (9 mg/day) was started. EGD revealed healing of the duodenal ulcers seven months after treatment. To our knowledge, this is the first report describing EGE-associated duodenal ulcer successfully treated with crushed budesonide.

Rare malignant ulcer related to primary intestinal diffuse large B-cell lymphoma: A case report

RATIONALE

The specific pathogenesis of the diffuse large B-cell lymphoma(DLBCL)is still indefinite and argumentative. It is known that DLBCL is the most common type of non-Hodgkin's lymphomas (NHL). A lot of cases of DLBCL such as primary gastric diffuse large B-cell lymphoma(PG-DLBCL) are reported. However, primary intestinal diffuse large B-cell lymphoma(PI-DLBCL) is unusual.

PATIENT CONCERNS

We present a case of a 57-year-old male diagnosed in the Gastroenterology Department, which presented a bleeding duodenal ulcer with irregular borders.

DIAGNOSES

The immunohistochemical staining showed: CD20(+++), CD10(+) and Ki-67>40%.

INTERVENTIONS

The patient was successfully treated by Poly-chemotherapy with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vindesine and prednisolone).

OUTCOMES

After 6 courses of chemotherapy treatment, the duodenal ulcer was completely healed by reviewing the UGIE.

LESSONS

Our report might give further strength to avoiding the erroneous and missed diagnosis for PI-DLBCL which is different from common duodenal ulcer.

Carrying a 112 bp-segment in Helicobacter pylori dupA may associate with increased risk of duodenal ulcer

The discovery of Helicobacter pylori in 1983 challenged researchers around the world to identify this pathogen's major virulence factors. The main rationale for this kind of research was to identify a biomarker associated with specific diseases following H. pylori colonization. Among different investigated virulence factors, duodenal ulcer promoting gene A (dupA) has been found to be associated with duodenal ulcer (DU), but its effect was different in various geographical regions. To determine the prevalence of dupA, we applied both classic primer pairs and our newly developed primers producing a highly conserved segment in PCR method. In our survey, 143 (47%) H. pylori isolates were obtained from 304H. pylori-colonized individuals [age range of 19-92; 113 (37%) males with the mean age of 50 and 191 (63%) females with the mean age of 49]. The presence of the dupA gene was investigated by using the different specific primers. The prevalence of the 112 bp segment isolated from H. pylori strains recovered from DU, GU and atrophy groups were significantly higher (81%, p value = .002, 64%, p = .065, 68% and p = .047 38%, respectively) than our control group, where the prevalence of the 112 bp segment was only 38%. Interestingly, a significant relationship was observed between the occurrence of DU and the presence of the 112 bp segment [p = .002; OR: 6.98; (95% CI: 1.94-25.00)]. Taken as a whole, we believe the 112 bp region of H. pylori dupA may serve as the first detected biomarker for the early detection of DU in patients admitted to hospitals.

Virulence factor genotyping of Helicobacter pylori isolated from Costa Rican dyspeptic patients

BACKGROUND AND AIMS

Costa Rica is one of the countries with the highest incidence and mortality rates for gastric cancer. Helicobacter pylori infection rates are high in the whole country. We have previously shown that H. pylori CagA+ is significantly associated with atrophic gastritis (AG) of the antrum in a dyspeptic population. The aim of this work is to determine if other H. pylori virulence factors (vacA, dupA, oipA, iceA and babA2) are associated with atrophic gastritis (AG) or duodenal ulcer (DU).

METHODS

The presence of virulence genes in Costa Rican H. pylori isolates was analyzed by PCR in 151 cultured strains from patients with dyspeptic symptoms. Endoscopic and histopathological diagnoses were available. Odds-ratio and 95% confidence intervals for AG patients vs. non-atrophic gastritis (NAG) or DU patients vs. no duodenal ulcer (NDU) patients were calculated.

RESULTS

Amongst the studied isolates, 82% had the cagA⁺, 76.2% had the vacA s1m1, 97.0% had the oipA⁺, 21.0% had the icea1, 79.0% had the iceA2, 44.0% had the babA2⁺ and 76.0% the dupA⁺ genotypes. Infection with H pylori cagA⁺, dupA⁺, oipA⁺, iceA, babA2⁺, and vacA s1m1 genotypes was not associated with AG risk. The frequency of the dupA gene was 78.7 and 60.9% in isolates from patients with NDU and DU, respectively, and its presence was significantly associated with decreased risk of duodenal ulcer [odds-ratio: 0.33, p = 0.024, confidence interval 95% (0.11-0.85)].

CONCLUSION

H. pylori dupA genotype is inversely associated with DU risk in this population.

Cumulative exposure to nighttime environmental noise and the incidence of peptic ulcer

BACKGROUND

Exposure to noise poses auditory and non-auditory effects on health. The gastrointestinal tract is considered as the site of adverse reactions to noise-induced stress; little attention has been paid to a potential link between noise and peptic ulcers.

OBJECTIVES

The aim of this study was to investigate whether cumulative exposure to environmental noise affects the incidence of peptic ulcer in adults.

METHODS

We analyzed the data from the National Health Insurance Service-National Sample Cohort (2002-2013). The final study sample comprised 217,308 adults assessed for gastric ulcer and 249,514 adults assessed for duodenal ulcer. The diagnosis of gastric (ICD-10: K25) and duodenal (ICD-10: K26) ulcers during an 8-year follow-up (2006-2013). Environmental noise data was obtained from the National Noise Information System, a nationwide monitors system of noise.

RESULTS

During the follow-up period, gastric ulcers occurred in 32.1% subjects and duodenal ulcers occurred in 10.7% subjects. The rate of diagnosis for gastric and duodenal ulcers was increased with the increases in cumulative mean levels of nighttime environmental noise. With increases in the increase in interquartile range (IQR) of nighttime noise, the hazard ratio (HR) was significantly increased by 12% (HR = 1.12; 95% CI, 1.10-1.13) for gastric ulcer and 17% (HR = 1.17; 95% CI, 1.15-1.20) for duodenal ulcer based on the fully adjusted model.

CONCLUSION

Our finding supports previous reports on the damaging effect of environmental noise on the gastrointestinal tract and suggests that cumulative exposure to environmental nighttime noise affects the development of peptic ulcers.

Gastrointestinal Complications of the Haemolytic Uraemic Syndrome

The haemolytic uraemic syndrome (HUS) is a well recognized cause of acute renal failure in children. Gastrointestinal involvement is common, and may result in rectal bleeding which can be an important presenting symptom. Previous publications have stressed the importance of correct diagnosis to avoid unnecessary surgery. Occasionally serious gastrointestinal complications do occur. We present five children with life-threatening gastrointestinal complications of the HUS and discuss the indications for laparotomy.

Perforated Duodenal Ulcer and Cigarette Smoking

Whilst the association between smoking and peptic ulceration has been reported previously, the relationship between smoking and the complications of ulcers, such as perforation, bleeding or acute painful exacerbation, has not been examined. In a retrospective study comparing 275 emergency admissions for peptic ulcer with 275 controls, cigarette smoking was significantly more common only in those with a perforated duodenal ulcer. Of 128 patients with perforated duodenal ulcers, 110 (86%) were cigarette smokers compared with 65 (51%) of the 128 matched controls (χ2, P<0.01). Cigarette smoking in patients with bleeding or acutely exacerbated ulcers was not significantly more common than in controls. These findings strongly suggest a particular association between smoking and perforated duodenal ulcer.

[Risk factors for adverse course of gastric and duodenal peptic ulcer]

OBJECTIVE

Introduction: High morbidity rate, frequent relapses, and significant economic losses give reasons for highlighting the peptic ulcer disease as the most topical medical-statistical problem. The aim of the study is to assess the influence of the main risk factors on the course of gastric and duodenal peptic ulcer.

PATIENTS AND METHODS

Materials and methods: We formed up the risk groups consisted of patients with 12 modified (4) and regular (8) factors, each characterized with its own signs and gradations. We performed the quantitative evaluation of the factors and scored the signs thereof, the results of which were used for determination of the most informative ones.

RESULTS

Results: Among the regular factors, we placed emphasis on gender, age, burdened heredity, and 0(I), Rh+ blood type. The risk of peptic ulcer in hereditary tainted young men of the working age with parental lineage (+2.3) and in males with 0(I) Rh+ blood type (+1.4) was proved. Helicobacter pylori (Hp) infection is a key contributor (a predictor of) to severity of the disease course (+9.7) among the modified risk factors. Negative effect of a concomitant pathology (+5.0), including hepatobiliary lesions (+3.8), hypertension (+4.0), and diabetes mellitus (+1.3) is also significant. Diet violation (+3.7), tobacco smoking (+3.2) and stress (+3.0) were ranked third.

CONCLUSION

Conclusions: The results of quantitative evaluation of the factors scoring suggest of the underlying H.pylori infection (the significance of which is growing along with the growth of the disease incidence) and irrational diet as the most informatively important ones. We have established the direct dependence between the most important peptic ulcer risk factors, severity of the disease, and duration and periodicity of treatment thereof.

Eosinophilic gastroenteritis presenting as upper gastrointestinal hematoma and ulcers after endoscopic biopsy: A case report and literature review

RATIONALE

Eosinphilic gastroenteritis (EG) is a gastrointestinal disorder characterized by eosinophilic infiltration with various manifestations. The diagnosis is usually confirmed by an endoscopic biopsy, which is considered a safe and routine procedure for the majority.

PATIENT CONCERNS

We report a 54-year-old male who was presented with intermittent periumbilical pain and melena, and only revealed verrucous gastritis by endoscopy.

DIAGNOSES

The patient's condition worsened two days after the endoscopic biopsy, and another endoscopy found hematoma and ulcers in upper gastrointestinal tract. He was diagnosed with EG by the pathological analysis of biopsy specimen.

INTERVENTIONS

Oral methylprednisolone and Montelukast were prescribed.

OUTCOMES

The patient got remission after initiation of the treatment.

LESSONS

This case highlights an extremely rare but potentially severe complication of endoscopic biopsies in patients with EG. Physicians should be cautious with hematoma or ulceration, and consider it in such patients who undergo this procedure.

Upper gastrointestinal haemorrhage in severe dengue: To scope or not to scope?

Upper gastrointestinal haemorrhage (UGIH) in severe dengue represents a clinical dilemma in term of management. The recommended treatment in dengue with UGIH involves blood product transfusion support and proton pump inhibitor (PPI) infusion. Despite being the mainstay of treatment in non-dengue UGIH, the role of endoscopic haemostatic intervention in severe dengue remains controversial. In the present report, we present a case of severe dengue complicated with upper gastrointestinal haemorrhage successfully underwent early therapeutic endoscopic intervention in a district hospital.

Successful Treatment with Adalimumab for Intestinal Behcet's Disease during Pregnancy

A 36-year-old Japanese woman with intestinal Behcet's disease was admitted to our hospital due to a recurrent ileocecal ulcer. Because infliximab (IFX) showed secondary failure, IFX was switched to adalimumab (ADA). After the third injection of ADA, she was unexpectedly 4-weeks pregnant. ADA was continued until 20 gestational weeks. Remission of the disease activity was maintained during pregnancy, and the birth was uneventful. The ileocecal ulcer disappeared after her delivery. ADA was detected in the umbilical blood after 119 days from the last infusion. The placental transition and timing of neonatal vaccination should be considered in cases of pregnancy with TNF antibody therapy.

Perforated duodenal ulcer: An unusual manifestation of allergic eosinophilic gastroenteritis

Spontaneous perforation of a duodenal ulcer secondary to allergic eosinophilic gastroenteritis (EGE) has not been previously reported. We present such a case in a teenager who presented with peritonitis. After exploration and operative repair of his ulcer, he continued to experience intermittent abdominal pain, and further evaluation revealed eosinophilic gastroenteritis in the setting of multiple food allergies. His EGE resolved after adhering to a restrictive diet. Both duodenal ulcers and EGE are very rarely seen in pediatric patients. EGE has a variable presentation depending on the layer(s) of bowel wall affected and the segment of the gastrointestinal tract that is involved. Once diagnosed, it may respond to dietary changes in patients with recognized food allergies, or to steroids in patients in whom an underlying cause is not identified. Our case highlights the need to keep EGE in the differential diagnosis when treating pediatric patients with duodenal ulcers. The epidemiology, pathophysiology, and treatment of EGE are also discussed, along with a review of the current literature.

[The drugs for H. pylori eradication therapy]

H. pylori eradication significantly inhibited ulcer recurrence in Japanese peptic ulcer patients. In Japan, 12 months after treatment, gastric ulcers had recurred in 11.4% of those with successful H. pylori eradication and 64.5% of those with unsuccessful H. pylori eradication. Duodenal ulcers had recurred in 6.8% of patients for whom H. pylori eradication was successful and in 85.3% of patients in whom eradication failed. About long-term study, 4 years after treatment, gastric ulcers had recurred in 9.3% of those with successful H. pylori eradication and duodenal ulcers recurrence was occurred in 6.2% of those. The annual recurrence rates of gastric, duodenal ulcer were 2.3% and 1.6%, respectively. However, in current Japan, the decrease of the primary eradication rate is reported by the increase of clarithromycin-resistant strains. The increase of metronidazole-resistant strains used for the second eradication is not recognized so far, but in future, increase is concerned about. Therefore, the making of the regimen of the third-line eradication therapy is needed now.

[Gastric ulcer, duodenal ulcer]

Recently, the acid secretion amount is increased by westernization of foods and Helicobacter pylori (H. pylori) infected patient's decrease in Japanese. Therefore, the recent tendencies are decrease of peptic ulcer diseases by H. pylori infection and increase of non-steroidal anti-inflammatory drugs(NSAIDs) ulcers. The endoscopic hemostasis should be performed for upper gastrointestinal bleeding from peptic ulcers in the first choice. A surgery or interventional radiology (IVR) should be performed in the unsuccessfulness of endoscopic hemostasis. H. pylori eradication therapy is effective for healing and prevention of recurrence from peptic ulcers. For prevention of recurrence of NSAIDs ulcers, therapy with proton pump inhibitor is effective.

[Ulcerated duodenitis revealing Henoch-Schönlein purpura]

Inflammation and duodenal ulcers can meet many etiologies. We report the case of a young adult with an ulcerated duodenitis revealing Henoch-Schönlein purpura. The abdominal symptoms preceded the emergence of the classical cutaneous signs of the disease.

Role of dietary polyphenols in the management of peptic ulcer

Peptic ulcer disease is a multifactorial and complex disease involving gastric and duodenal ulcers. Despite medical advances, the management of peptic ulcer and its complications remains a challenge, with high morbidity and death rates for the disease. An accumulating body of evidence suggests that, among a broad reach of natural molecules, dietary polyphenols with multiple biological mechanisms of action play a pivotal part in the management of gastric and duodenal ulcers. The current review confirmed that dietary polyphenols possess protective and therapeutic potential in peptic ulcer mediated by: improving cytoprotection, re-epithelialization, neovascularization, and angiogenesis; up-regulating tissue growth factors and prostaglandins; down-regulating anti-angiogenic factors; enhancing endothelial nitric oxide synthase-derived NO; suppressing oxidative mucosal damage; amplifying antioxidant performance, antacid, and anti-secretory activity; increasing endogenous mucosal defensive agents; and blocking Helicobacter pylori colonization associated gastric morphological changes and gastroduodenal inflammation and ulceration. In addition, anti-inflammatory activity due to down-regulation of proinflammatory cytokines and cellular and intercellular adhesion agents, suppressing leukocyte-endothelium interaction, inhibiting nuclear signaling pathways of inflammatory process, and modulating intracellular transduction and transcription pathways have key roles in the anti-ulcer action of dietary polyphenols. In conclusion, administration of a significant amount of dietary polyphenols in the human diet or as part of dietary supplementation along with conventional treatment can result in perfect security and treatment of peptic ulcer. Further well-designed preclinical and clinical tests are recommended in order to recognize higher levels of evidence for the confirmation of bioefficacy and safety of dietary polyphenols in the management of peptic ulcer.

Role of dietary phospholipids and phytosterols in protection against peptic ulceration as shown by experiments on rats

Geographically the prevalence of duodenal ulceration is related to the staple foods in the diet in regions of developing countries where the diet is stable. It is higher in regions where the diet is based on milled rice, refined wheat or maize, yams, cassava, sweet potato, or green bananas, and is lower in regions where the staple diet is based on unrefined wheat or maize, soya, certain millets or certain pulses. Experiments on rat gastric and duodenal ulcer models showed that it was the lipid fraction in staple foods from low prevalence areas that was protective against both gastric and duodenal ulceration, including ulceration due to non-steroidal anti-inflammatory drugs (NSAIDs). It also promoted ulcer healing. The lipid from the pulse, Dolichos biflorus, horse gram which was highly protective was used to identify the fractions with protective activity in the lipid. The protective activity lay in the phospholipid, sterol and sterol ester fractions. In the phospholipid fraction phosphatidyl choline (lethicin) and phosphatidyl ethanolamine (cephalin) were predominant. In the sterol fraction the sub-fractions showing protective activity contained β-sitosterol, stigmasterol, and an unidentified isomer of β-sitosterol. The evidence from animal models shows that certain dietary phospholipids and phytosterols have a protective action against gastroduodenal ulceration, both singly and in combination. This supports the protective role of staple diets in areas of low duodenal ulcer prevalence and may prove to be of importance in the prevention and treatment of duodenal ulceration and management of recurrent ulcers. A combination of phospholipids and phytosterols could also play an important role in protection against ulceration due to NSAIDs.

A Duodenal Ulcer Caused by Pancreatic Ductal Hypertension with Chronic Pancreatitis

We herein describe the case of a 67-year-old woman with a duodenal ulcer thought to be caused by elevated pancreatic ductal pressure. The patient complained of continuous upper abdominal pain. Her medical history included idiopathic chronic pancreatitis. Endoscopy revealed a huge duodenal ulcer located on the inferior duodenal angle, which had not been seen on endoscopic retrograde pancreatography two months previously. A combination study using endoscopy and contrast imaging confirmed the relationship between the duodenal ulcer and the pancreatic branch duct. To our knowledge, this is the first case of duodenal ulcer thought to be caused by elevated pancreatic ductal pressure.

Bleeding gastric metastases from cutaneous melanoma

7% of gastrointestinal tract (GIT) involvements with metastatic cutaneous melanoma concerns the stomach. The aim of the study was to describe a rare case of the cutaneous melanoma metastazing to the stomach.

MATERIAL AND METHODS

. Bearing in mind the rarity of such cases, we present our experiences based on the history of 42-year-old woman, who underwent surgical excision of skin tumour located on the trunk.

RESULTS

Histopathological examination of the skin tumor led to the diagnosis of melanoma (Clark IV, Breslow 5mm) with ulceration and a number of mitoses 40/10 HPF. PET-CT demonstrated multiple organ dissemination. Patient was admitted to the hospital due to severe, symptomatic anaemia. RBC and FFP transfusions were necessary. Gastroscopy revealed multiple gastric and duodenal ulcers and histopathology confirmed metastatic melanoma. Attempts to achieve endoscopic hemostasis were ineffective due to the extent of lesions.

CONCLUSION

In the presence of any alarming GIT symptoms or unclear anaemia, any physician treating patient with a history of melanoma should exclude metastatic tumour. Endoscopy may be useful both for the diagnosis and local treatment of gastric metastases and should be routinely and cautiously conducted.

Helicobacter pylori from gastric cancer and duodenal ulcer show same phylogeographic origin in the Andean region in Colombia

Background

A recent report has shown that the phylogenetic origin of Helicobacter pylori based on multi-locus sequence typing (MLST) was significantly associated with the severity of gastritis in Colombia. However, the potential relationship between phylogenetic origin and clinical outcomes was not examined in that study. If the phylogenetic origin rather than virulence factors were truly associated with clinical outcomes, identifying a population at high risk for gastric cancer in Colombia would be relatively straightforward. In this study, we examined the phylogenetic origins of strains from gastric cancer and duodenal ulcer patients living in Bogota, Colombia.

Methods

We included 35 gastric cancer patients and 31 duodenal ulcer patients, which are considered the variant outcomes. The genotypes of cagA and vacA were determined by polymerase chain reaction. The genealogy of these Colombian strains was analyzed by MLST. Bacterial population structure was analyzed using STRUCTURE software.

Results

H. pylori strains from gastric cancer and duodenal ulcer patients were scattered in the phylogenetic tree; thus, we did not detect any difference in phylogenetic distribution between gastric cancer and duodenal ulcer strains in the hpEurope group in Colombia. Sixty-six strains, with one exception, were classified as hpEurope irrespective of the cagA and vacA genotypes, and type of disease. STRUCTURE analysis revealed that Colombian hpEurope strains have a phylogenetic connection to Spanish strains.

Conclusions

Our study showed that a phylogeographic origin determined by MLST was insufficient for distinguishing between gastric cancer and duodenal ulcer risk among hpEurope strains in the Andean region in Colombia. Our analysis also suggests that hpEurope strains in Colombia were primarily introduced by Spanish immigrants.

[Clinical and morphological peculiarities of the clinical course of duodenal ulcer in patients with bronchial asthma]

This work was aimed to study clinical features of H. pylori-associated duodenal ulcer (DU) and elucidate morphological features of gastric mucosa (GM) in patients with bronchial asthma (BA). Simultaneous prospective examination of 118 patients aged 18-64 yr included clinical and endoscopic study of the gastroduodenal region with the assessment of gastroenterological symptoms and morphological analysis of GM and duodenal biopsies by histological, histochemical, and morphometric methods. It was shown that GM inflammation in patients with DU and BA is associated not only with H. pylori infection but also with the phase of BA. Structural changes of GM in the patients with DU and BA, unlike those with DU without BA, were apparent not only in the antrum but also in the fundus. Growing density of eosinophil, neutrophil and mast cell infiltration of fundal and antral GM as well as increased total number of cells in the antrum reflects active immune-mediated inflammation in GM lamina propria. It is concluded that negative effect of uncontrolled BA on the clinical course of DU is not restricted to the association of DU exacerbation with the absence of BA control; it is also responsible for enhanced activity of gastritis. One of the possible factors determining combination of H. pylori-associated duodenal ulcer with BA is chronic hyperergic inflammation and marked structural changes in GM.

[Peculiarities of clinical picture of duodenal ulcer in the population of Northern Europe]

Duodenal ulcer remains a serious challenge to gastroenterology due to the difficulty of its management despite recent progress in this field. The role of melatonin in human body has attracted much attention of researchers in the recent years. Disturbances of its production are widely recognized to be involved in pathogenesis of duodenal ulcer and its exacerbation. This review summarizes results of research on the clinical picture of the disease in the population of European North where circadian and seasonal variations in melatonin production are most strongly pronounced.

A review of the management of perforated duodenal ulcers at a tertiary hospital in south western Nigeria

BACKGROUND

Gastro-duodenal perforations are common and may complicate peptic ulcer disease. Management is often by surgical closure.

OBJECTIVE

To determine the patterns of presentation and mode of management of duodenal ulcer perforations.

METHODS

Retrospective review of patients with duodenal ulcer perforations seen at the Obafemi Awolowo University Teaching Hospital between June 2001 and July 2011. Patients' records were reviewed for demography, duration of disease, probable risk factors, type of surgery and complications. Data obtained was analyzed using SPSS 15.0.

RESULT

Forty- five patients were reviewed. There were 37 males (82.2%). Mean age was 39.7years (range 15-78years). There were 10 (22.6%) students and 8(17.8%) farmers. NSAIDs abuse (11), previous peptic ulcer disease (2), and no prior dyspeptic symptoms (20) constituted 24.4%, 4.4% and 44.4% respectively of cases. Seven (16%) patients presented less than 24 hours of onset of illness. Forty one perforations (91.1%) involved the first part of duodenum. Twenty two (49%) patients had Graham's omental patch. We had one (2.2%) failed repair and six (13.3%) mortalities.

CONCLUSION

Late presentation of duodenal ulcer perforation is common with high mortality. Pragmatic surgical intervention with Graham's omentopexy with broad spectrum antibiotics is still commonly practiced.

[Possible role of genetic factors on reduced risk for gastric cancer among duodenal ulcer patients]

Although H. pylori causes both gastric cancer and peptic ulcer, duodenal ulcer patients were known to have low risk for gastric cancer. Recently the association of PSCA and ABO with duodenal ulcer were identified by GWAS in the Japanese population. A T-allele of SNP rs2294008 in the PSCA promoter creates the upstream translational initiation codon and affects the protein localization from cytoplasm to cell surface. A T-allele of SNP rs2294008 increased gastric cancer risk but reduced duodenal ulcer risk. In addition, blood type O was shown to increase risk for duodenal ulcer, while blood type A was associated with gastric cancer risk in the Caucasian population. Our finding would partially explain low risk of gastric cancer among duodenal ulcer patients.

[Gastric ulcer and duodenal ulcer]

Peptic ulcer diseases are improved by strong acid suppression therapy. However, peptic ulcer diseases are often relapsed after discontinuing of acid suppression therapy. After discovery of Helicobacter pylori (H. pylori) in 1984, H. pylori is known as the strongest causal agent for peptic ulcer diseases. In November 2000, eradication therapy for H. pylori infection was approved under the Japanese system of health insurance. H. pylori eradication reduces ulcer recurrence dramatically. Recently, peptic ulcer diseases induced by NSAIDs and/or aspirin are increasing. In prevention of NSAIDs and/or aspirin induced peptic ulcer recurrence, H. pylori eradication plus PPI treatment is recommended. Several reports described occurrence of newly-developed gastric cancer after H. pylori eradication. Careful follow-up upper gastrointestinal endoscopy is necessary after H. pylori eradication.

[Perforated duodenal diverticula. Case report and treatment options]

BACKGROUND

the presence of duodenal diverticula was first described in 1710 by Chromel. Duodenal diverticulum is the second most common site of diverticula in the digestive tract. Anatomically duodenal diverticula are located in 10 to 67% in the second portion of duodenum, and its finding in most cases incidental. About 90% of patients appear asymptomatic, manifesting symptoms mostly once established complications such as: gastrointestinal bleeding and perforation.

CLINICAL CASE

78-years-old woman who attended our Emergency department with dyspnea, moderate epigastralgia, abdominal bloating, constipation and difficulty to pass gas; Laparotomy was performed to identify duodenal diverticulum in the third portion of the duodenum with a perforation of 5 mm in its cupula. It proceeds with diverticulectomy.

CONCLUSIONS

The diagnosis of duodenal diverticulum as a cause of acute abdomen must be considered in our differential diagnosis in acute abdomen supported by imaging and endoscopy. The surgical management of duodenal diverticulum, in particular the resection of the diverticulum, remains as the recommendation for treatment with less morbidity and a good recovery.

Predictive factors for gastroduodenal toxicity based on endoscopy following radiotherapy in patients with hepatocellular carcinoma

PURPOSE

The aim of this work was to determine predictive factors for gastroduodenal (GD) toxicity in hepatocellular carcinoma (HCC) patients who were treated with radiotherapy (RT).

PATIENTS AND METHODS

A total of 90 HCC patients who underwent esophagogastroduodenoscopy (EGD) before and after RT were enrolled. RT was delivered as 30-50 Gy (median 37.5 Gy) in 2-5 Gy (median 3.5 Gy) per fraction. All endoscopic findings were reviewed and GD toxicities related to RT were graded by the Common Toxicity Criteria for Adverse Events, version 3.0. The predictive factors for the ≥ grade 2 GD toxicity were investigated.

RESULTS

Endoscopic findings showed erosive gastritis in 14 patients (16 %), gastric ulcers in 8 patients (9 %), erosive duodenitis in 15 patients (17 %), and duodenal ulcers in 14 patients (16 %). Grade 2 toxicity developed in 19 patients (21 %) and grade 3 toxicity developed in 8 patients (9 %). V25 for stomach and V35 for duodenum (volume receiving a RT dose of more than x Gy) were the most predictive factors for ≥ grade 2 toxicity. The gastric toxicity rate at 6 months was 2.9 % for V25 ≤ 6.3 % and 57.1 % for V25 > 6.3 %. The duodenal toxicity rate at 6 months was 9.4 % for V35 ≤ 5.4 % and 45.9 % for V35 > 5.4 %. By multivariate analysis including the clinical factors, V25 for stomach and V35 for duodenum were the significant factors.

CONCLUSION

EGD revealed that GD toxicity is common following RT for HCC. V25 for the stomach and V35 for the duodenum were the significant factors to predict ≥ grade 2 GD toxicity.

Long-term follow-up study of gastroduodenal lesions after radioembolization of hepatic tumors

AIM: To evaluate the long-term natural history of the gastroduodenal lesions secondary to extrahepatic embolization with Ytrium 90 (⁹⁰Y) spheres.

METHODS: From September 2003 to January 2012, 379 procedures of liver radioembolization (RE) using resin microspheres loaded with ⁹⁰Y were performed in our center. We have retrospectively compiled the data from 379 RE procedures performed in our center. We report a comprehensive clinical, analytical, endoscopic and histologic long-term follow-up of a series of patients who developed gastroduodenal lesions after the treatment.

RESULTS: Six patients (1.5%) developed gastrointestinal symptoms and had gastrointestinal lesions as shown by upper endoscopy in the next 12 wk after RE. The mean time between RE and the appearance of symptoms was 5 wk. Only one patient required endoscopic and surgical treatment. The incidence of gastrointestinal ulcerations was 3.75% (3/80) when only planar images were used for the pre-treatment evaluation. It was reduced to 1% (3/299) when single-photon emission computed tomography (SPECT) images were also performed. The symptoms that lasted for a longer time were nausea and vomiting, until 25 mo after the treatment.

CONCLUSION: All patients were free from severe symptoms at the end of follow-up. The routine use of SPECT has decreased the incidence of gastrointestinal lesions due to unintended deployment of ⁹⁰Y particles.

Duodenal ulcer penetration into the superior mesenteric artery after percutaneous transluminal angioplasty and stent placement for acute mesenteric ischemia: report of a case

A 78-year-old male presented with the chief complaints of abdominal pain and vomiting. Contrast-enhanced computed tomography and abdominal angiography showed occlusion of the superior mesenteric artery due to thrombosis, and emergency percutaneous transluminal angioplasty and stent placement were carried out. Two months later, stent thrombosis developed, and a second stent was placed. Eight months later, he complained of general fatigue and anorexia. Gastrointestinal endoscopy revealed a duodenal ulcer at the third portion close to the superior mesenteric artery. Thirteen days after conservative management, duodenal ulcer penetration into the superior mesenteric artery with subsequent air embolism developed, and the patient died of multiple organ failure.

[Influence of the comorbidity diseases and risk factors on development of the combined peptic ulcer of the stomach and the duodenum]

RESEARCH OBJECTIVE

To define influence of the comorbidity diseases and risk factors of development of the combined peptic ulcer of a stomach and duodenum.

MATERIALS AND METHODS

As a result of carried-out poll and inspection 250 patients with an exacerbation of a peptic ulcer were surveyed. Patients were distributed in 3 groups of observation depending on localization of ulcerative process. At all surveyed questioning was carried out, data on hereditary load, smoking, alcohol intake, existence of somatopathies were specified, clinic-morphological implications of a peptic ulcer were studied.

RESULTS

The peptic ulcer of a stomach is characteristic for women (72.1%) and develops mainly aged from 45 till 59 years (60.3%). Peptic ulcer of duodenum men (76.3%) suffer mainly, the debut is the share in most cases of age from 18 to 44 years (79.1%). The combined canker of a stomach and duodenum meets at males (61.2%) more often, is initially involved in process ulcerogenesis by duodenum generally aged from 30 till 44 years (64.2%), accession of a canker of a stomach happens is delayed (at 38.8% within 16 and more years). In the analysis of risk factors at patients with the combined peptic ulcer of a stomach and duodenum depending on existence or absence specific to this category of patients of a background from such comorbidity diseases as IBS, HOBL and widespread osteochondrosis taped that larger prevalence of smoking (100%) and as the use (50%) and the excessive use (50%), alcohol are characteristic for the patients having a high comorbidity (a combination of three above nosologies).

CONCLUSION

The greatest interest in respect of possible communication with formation of the combined peptic ulcer of a stomach and duodenum is represented by IBS, HOBL and osteochondrosis. And major factors of risk were smoking, the excessive alcohol intake, the burdened heredity.

[Clinic pathogenetic features of gastroduodenal erosions and ulcers in patients with unstable stenocardia]

OBJECTIVE

To reveal the clinical, morphological and pathogenic features of gastroduodenal erosions and ulcers in unstable angina.

METHODS

135 patients with unstable angina were examined and divided into 2 groups, depending on the presence of a pathological process in the gastroduodenal zone. The state of microcirculation in the tissues of the gastroduodenal zone, secretory and motor function of the stomach were estimated by complex of techniques, adapted to the severity of the patients.

RESULTS

It is found that the pathological process in the gastroduodenal zone in patients with unstable angina was presented primarily by acute erosions, less - acute ulcers or recurrent peptic ulcer disease. In this case, the leading symptom of acute erosions was dyspepsia, that as a rule prevailed over the indistinct abdominal pain, and often disappeared in the first few days of treatment. Clinical picture of acute ulcers was determined by gastric dyspepsia and was often combined with abdominal pain and symptoms of gastrointestinal bleeding. The recurrence of peptic ulcer disease was characterized by the combination of moderate abdominal pain, often with migration in retrosternal and cardiac area and loss of circadian rhythm inherent in anthro-duodenal ulcer localization, and dyspeptic disorders. The severity of symptoms of ulcerous process was gradually decreased with time, but in most patients, they had remained by the end of the 2nd week of treatment. The basis of development of erosions and ulcers in unstable angina were the focal mainly thrombohaemorrhagic disorders of the terminal blood flow in the gastroduodenal mucosa. Its were combined with changes in the functional state of the stomach, manifested with an increase activity of acid-peptic factor, reduced production of gastromucoproteins, hypomotor dyskinesia and discoordination of anthro-duodenal propulsion on the hypotonic type.

CONCLUSION

Erosive and ulcerative lesions of gastroduodenal zone in unstable angina have a number of clinical and pathogenetic features that should be considered in the process of diagnosis and treatment.

Helicobacter pylori is not the predominant etiology for peptic ulcers requiring operation

As the number of patients requiring operation for peptic ulcer disease (PUD) declines, presumed contemporary ulcer etiology has largely been derived from medically treated patients not subjected to surgery. The purpose of this study was to examine the specific causes of PUD in patients requiring surgery. Our Acute Care Surgical Service registry was reviewed for patients operated on for complications of PUD from 2004 to 2009. Emphasis was placed on individual etiologic factors for PUD. There were 128 patients (52% male, 81% white) who underwent emergency operation including: simple patch closure (n = 61, 48%); gastric resection (n = 22, 17%); gastric resection with vagotomy (n = 21, 16%); vagotomy and pyloroplasty (n = 18, 14%); or other procedures (n = 6, 5%). Complications necessitating operation were perforation (n = 79, 62%); bleeding (n = 29, 23%); obstruction (n = 12, 9%); and intractability (n = 8, 6%). Perioperative mortality was 12.5 per cent. Risk factors for PUD included tobacco use (50%), alcohol abuse (34%), and steroids (21%). Nonsteroidal anti-inflammatory use was confirmed in 68 (53%) patients. Of the 128 patients, 82 (64%) were tested for Helicobacter pylori, 33 (40%) of which were positive and 49 (60%) negative. Helicobacter pylori, thus, was the confirmed ulcer etiology in only 26 per cent of cases. Unlike contemporary series of medically treated PUD, Helicobacter pylori may not be the predominant etiologic factor in patients who experience complications requiring surgery. A "traditional" surgical approach with liberal use of vagotomy, not antibiotic triple therapy, may well be the preferred treatment consideration in such cases.

The content of elements in rainwater and its relation to the frequency of hospitalization for gastric and duodenal peptic ulcers in Opole Voivodship, Poland, during 2000-2002

The relationship between chemical elements in rainwater and the frequency of hospitalizations for gastric and duodenal peptic ulcers was studied on the population of the province (Voivodship) of Opole, Poland, during the years 2000-2002. There is a high positive correlation between hospitalized cases of gastric peptic ulcers with chromium in rainwater (r = 0.71), cadmium (r = 0.63), and lead (r = 0.70). Mild positive correlations were found with zinc (r = 0.55), copper (r = 0.56), iron (r = 0.57), chloride (r = 0.60), and sulfate (r = 0.52). These correlations were higher on men, suggesting that there are gender correlations involved. In duodenal peptic ulcers, we observed a high positive correlation between chromium in rainwater and hospitalized cases (r = 0.61) and mild positive correlations with lead (r = 0.57), copper (r = 0.52), and cadmium (r = 0.51). Significant gender differences were not found. These positive correlations may be due to the biological activity of the elements, such as their cytotoxic activity, enhanced local adrenergic stimulation on mucosal vasculature, ion channel (mainly calcium channels) remodeling, and, for example promoting infection by Helicobacter pylori.

[Characteristics of duodenogastric reflux in duodenal ulcer patients and its dynamics after Helicobacter pylori eradication]

Studying role of duodenogastric reflux (DGR) in pathogenesis and sanogenesis of duodenal ulcer (DU).

MATERIAL AND METHODS

233 DU patients (92 patients with a mild, 45--with modern and 96--with the complicated current of disease) are surveyed. Control group were 100 healthy volunteers. Clinical research, endoscopy and 24-hours pH-metria was carried out. In a year after eradication Helicobacter pylori (Hp) 30 patients are repeatedly surveyed.

RESULTS

at healthy acidity more low, and DGR above and more for a long time, than at DU patients. DU was especially supressed at complicated current DU. Eradication Hp was accompanied by acidity normalization only at mild DU, and at complicated DU--is not present.

CONCLUSION

at healthy people DGR arises in reply to antrum's acidification and has compensative value, and at DU there is the considerable suppression leading to insufficiency of antrum's alkalization. After eradication Hp normalization DGR is marked only at mild current DU.

[The problems of etiology and pathogenesis of ulcer disease: rereading V. Kh. Vasilenko]

The author discusses the views of V. Kh. Vasilenko on etiology and pathogenesis of ulcer disease expounded in his last publications and compares them with modern concepts of the origin of this condition. The nature of ulcer disease as a systemic gastrointestinal pathology is considered with special emphasis on its difference from secondary (symptomatic) ulceration, pathogenetic significance of H. pylori infection, hereditary and environmental (non-infectious) factors. Much attention is given to the conditions facilitating the development of ulcer diseases at different combinations of internal and environmental factors including such poorly known ones as immune and sanogenetic mechanisms.

[Acute erosive gastropathies]

There is a rise in the rates of acute erosive gastropathies in patients with cardiovascular and other somatic diseases. The role of acute erosive gastropathy-induced hemorrhages in the tanatogenesis of these diseases is underestimated; the problems of their prevention, diagnosis, and treatment remained unsolved. Many factors, mainly acute or chronic ischemia of the gastroduodenal mucosa, as well as its age-related involution, Helicobacter pylori infection, reflux gastritis, multiple organ dysfunction, drug-induced damage, etc., which are implicated in the pathogenesis of acute erosive gastropathies in patients with cardiovascular and other somatic diseases, are summarized.

[Duodenal involvement in Henoch-Schonlein purpura. Report of a case]

Henoch-Schonlein purpura (HSP) is a systemic vasculitis of the small vessels of the skin, joints, gastrointestinal tract and kidneys. It is the most common cause of nonthrombocytopenic purpura in children, but may also occur in adults. Gastrointestinal symptoms and disease occurs in up to 85% of patients and can be of varying intensity. We report a 12 year old boy with gastrointestinal bleeding due to duodenal involvement associated with this condition evidenced by endoscopy.

[Acute gastroduodenal erosions and ulcers in coronary heart disease, cerebrovascular disease, and chronic obstructive pulmonary disease]

A total of 4684 autopsies made at Moscow multidisciplinary hospitals in 2002-2008 were studied to reveal the incidence and morphological features of acute gastroduodenal erosions and ulcers in coronary heart disease (CHD), cerebrovascular disease (CVD), and chronic obstructive pulmonary disease (COPD). Cases with combined, background, and concomitant diseases that could be independent causes of gastroduodenal lesions were excluded. Patients older than 60 years with infarctions of the myocardium or brain, a concurrence of CHD, CVD, and COPD, and various diseases with chronic heart failure syndrome, particularly in the presence of arterial hypertension and diabetes mellitus should be referred to as a risk group for acute gastroduodenal erosions and ulcers and their induced hemorrhages.
