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.

Link between Serum Pepsinogen Concentrations and Upper Gastrointestinal Endoscopic Findings

The serum pepsinogen (PG) assay findings are correlated with the status of Helicobacter pylori infection, but there are controversies on the link with upper gastrointestinal (UGI) endoscopic findings. The aim of this study was to determine the significance of a serum PG assay for correlating with endoscopic findings in H. pylori-seroprevalent adult population. Korean adults who visited for a health check-up were included consecutively. Subjects after gastrectomy or H. pylori eradication were excluded. After completing the serum PG assay and anti-H. pylori immunoglobulin G (IgG) titer on the same day of UGI endoscopy, subjects with equivocal serology test finding or gastric neoplasm were excluded. Of the 4,830 included subjects, 3,116 (64.5%) were seropositive for H. pylori. Seropositive finding was related to high serum PG I (P < 0.001) and PG II (P < 0.001) concentrations, low PG I/II ratio (P < 0.001), old age (P < 0.001), and male gender (P = 0.006). After adjusting age and gender, the serum PG I and II concentrations were positively correlated with the presence of nodular gastritis (NG) (all P = 0.003). The serum PG I was positively correlated with gastric ulcer (P = 0.003), and it was correlated with duodenal ulcer in seropositive subjects (P = 0.008). The PG I/II ratio was positively correlated with erosive esophagitis, while it was inversely related to chronic atrophic gastritis and metaplastic gastritis (all P < 0.001). Our findings suggest that the serum PG assay finding correlates well with the UGI endoscopic finding. A higher serum PG concentration in subjects with NG and peptic ulcer disease suggests that endoscopic findings reflect gastric secreting ability.

Clinical characteristics of peptic ulcer perforation in Korea

AIM

To elucidate the epidemiological characteristics and associated risk factors of perforated peptic ulcer (PPU).

METHODS

We retrospectively reviewed medical records of patients who were diagnosed with benign PPU from 2010 through 2015 at 6 Hallym university-affiliated hospitals.

RESULTS

A total of 396 patients were identified with postoperative complication rate of 9.1% and mortality rate of 0.8%. Among 174 (43.9%) patients who were examined for Helicobacter pylori (H. pylori) infection, 78 (44.8%) patients were positive for H. pylori infection, 21 (12.1%) were on non-steroidal anti-inflammatory drugs (NSAIDs) therapy, and 80 (46%) patients were neither infected of H. pylori nor treated by any kinds of NSAIDs. Multivariate analysis indicated that older age (OR = 1.09, 95%CI: 1.04-1.16) and comorbidity (OR = 4.11, 95%CI: 1.03-16.48) were risk factors for NSAID-associated PPU compared with non-H. pylori, non-NSAID associated PPU and older age (OR = 1.04, 95%CI: 1.02-1.07) and alcohol consumption (OR = 2.08, 95%CI: 1.05-4.13) were risk factors for non-H. pylori, non-NSAID associated PPU compared with solely H. pylori positive PPU.

CONCLUSION

Elderly patients with comorbidities are associated with NSAIDs-associated PPU. Non-H. pylori, non-NSAID peptic ulcer is important etiology of PPU and alcohol consumption is associated risk factor.

[New Swedish guidelines for the management of dyspepsia, H pylori, and duodenal and gastric ulcers]

New Swedish guidelines for the management of dyspepsia, H pylori, and duodenal and gastric ulcers The management of dyspepsia in Sweden differs between national county councils, and is often not in line with international recommendations. The Swedish Society of Gastroenterology has together with the Swedish College of General Practice (SFAM) developed new national guidelines for the management of uninvestigated dyspepsia, functional dyspepsia, Helicobacter pylori, and uncomplicated duodenal and gastric ulcers. The new Swedish guidelines emphasize that patients under 50 years of age with new onset of uninvestigated dyspepsia without any alarm symptoms or signs can be managed with the »Test and treat« strategy. Moreover, patients with a known H pylori infection and bothersome symptoms of functional dyspepsia shall be offered eradication therapy. The recommendations for triple therapy for H pylori eradication take into account the estimated average national antibiotic resistance patterns, environmental factors and potential effects on gut microbiota.

[Gastroenterology and hepatology in 2016]

This article aims to detail the major innovations occurred in Gastro-enterology in 2016, including the introduction of a new molecule, the vonoprazan, for the treatment of refractory gastroesophagal reflux disease (GERD) and a new way of eradication of H. pylori. The possibility to use an intermittent dose of PPI rather than continuously in severe gastric and duodenal ulcers after successful endoscopic hemostasis is also discussed as well as the withdrawal of corticosteroids in the treatment of autoimmune pancreatitis. The formulation of corticosteroids in the treatment of eosinophilic esophagitis, the interest of the chromo-endoscopy during colonoscopy highlighting small polyps (from 1 to 5 mm = « diminutive polyps ») and the introduction on the Swiss market for biosimilars in the treatment of inflammatory bowel disease (IBD) are also discussed.

Capsule endoscopy and single-balloon enteroscopy in small bowel diseases: Competing or complementary?

AIM

To evaluate diagnostic yields of capsule endoscopy (CE) and/or single-balloon enteroscopy (SBE) in patients with suspected small bowel diseases.

METHODS

We retrospectively analyzed 700 patients with suspected small bowel diseases from September 2010 to March 2016. CE, SBE, or SBE with prior CE was performed in 401, 353, and 47 patients, respectively. Data from clinical and endoscopy records were collected for analysis. Indications, procedure times, diagnostic yields, and complications were summarized and evaluated.

RESULTS

The overall diagnostic yield for the CE group was 57.6%. The diagnostic yield of CE in patients with obscure gastrointestinal bleeding (OGIB) was significantly greater than that in patients with no bleeding (70.5% vs 43.8%, P < 0.01). The overall diagnostic yield of SBE was 69.7%. There was no difference in the diagnostic yield of SBE between patients with OGIB and those with no bleeding (72.5% vs 68.9%, P = 0.534). Forty-seven patients underwent CE prior to SBE. Among them, the diagnostic yield of SBE with positive findings on prior CE was 93.3%. In addition, SBE detected two cases with superficial ulcer and erosive lesions in the small bowel, which were missed by CE. However, one case with lymphoma and two with Crohn’s disease were not confirmed by SBE. The rate of capsule retention was 2.0%. There were no significant complications during or after SBE examinations.

CONCLUSION

SBE is a safe and effective technique for diagnosing small bowel diseases. SBE with prior CE seemed to improve the diagnostic yield of small bowel diseases.

A prospective evaluation of 200 upper endoscopies performed in Alaska Native persons

OBJECTIVES

To characterize the nature and prevalence of disease in Alaska Native patients referred for evaluation of upper gastrointestinal signs and symptoms.

STUDY DESIGN

Cross-sectional.

METHODS

Two hundred consecutive Alaska Native patients referred to a statewide tertiary center were prospectively evaluated. A standardized data collection form documenting EGD findings was utilized. Routine biopsies of the antrum and fundus were taken on all patients. Additional tissue was obtained from any areas of clinical concern.

RESULTS

Among 200 patients who underwent EGD during the study period, 130 (65%) tested H. pylori-positive on histology. Among 173 patients with histologic evidence of gastritis, 114 (66%) tested H. pylori-positive on histology. Chronic gastritis (87%), gastric ulcer (GU 12%), duodenal ulcer (DU 3%) and gastric cancer (2%) were the predominant findings. The GU:DU ratio was 4:1, the inverse of that reported in the general U.S. population.

CONCLUSIONS

Alaska Native patients referred for upper endoscopy have a high rate of H. pylori infection with predominantly gastric manifestations of disease and a GU:DU ratio, which is the inverse of what is typically seen in the U.S. and other developed countries. The high prevalence of H. pylori in Alaska Native patients resembles prevalence patterns reported from developing countries and may be linked to a rate of gastric cancer that is over three times that found in the U.S. population at large.

Doppler endoscopic probe as a guide to risk stratification and definitive hemostasis of peptic ulcer bleeding

BACKGROUND AND AIMS

For more than 4 decades endoscopists have relied on ulcer stigmata for risk stratification and as a guide to hemostasis. None used arterial blood flow underneath stigmata to predict outcomes. For patients with severe peptic ulcer bleeding (PUB), we used a Doppler endoscopic probe (DEP) for (1) detection of blood flow underlying stigmata of recent hemorrhage (SRH), (2) quantitating rates of residual arterial blood flow under SRH after visually directed standard endoscopic treatment, and (3) comparing risks of rebleeding and actual 30-day rebleed rates for spurting arterial bleeding (Forrest [F] IA) and oozing bleeding (F IB).

METHODS

Prospective cohort study of 163 consecutive patients with severe PUB and different SRH.

RESULTS

All blood flow detected by the DEP was arterial. Detection rates were 87.4% in major SRH-spurting arterial bleeding (F IA), non-bleeding visible vessel (F IIA), clot (F IIB)-and were significantly lower at 42.3% (P < .0001) for an intermediate group of oozing bleeding (F IB) or flat spot (F IIC). For spurting bleeding (F IA) versus oozing (F IB), baseline DEP arterial flow was 100% versus 46.7%, residual blood flow detected after endoscopic hemostasis was 35.7% versus 0%, and 30-day rebleed rates were 28.6% versus 0% (all P < .05).

CONCLUSIONS

(1) For major SRH versus oozing or spot, the arterial blood flow detection rate by the DEP was significantly higher, indicating a higher rebleed risk. (2) Before and after endoscopic treatment, spurting (F IA) PUB had significantly higher rates of blood flow detection than oozing (F IB) PUB and a significantly higher 30-day rebleed rate. (3) The DEP is recommended as a new endoscopic guide with SRH to improve risk stratification and potentially definitive hemostasis for PUB.

[Peculiarities of the psychic state and quality of life in patients with duodenal ulcer in the context of chronomedicine]

Most clinicians consider duodenum ulcer as a psychosomatic disease. Objective: To show the interdependence of this condition and mental disorders and their relation to disturbances of melatonin production . Materials and Methods: 15 patients with seasonal DU and 15 healthy subjects of the control group were examined during 3 years using laboratory, endoscopic, and standard psychodiagnostic methods. Results. It was found that all patients with exacerbation of DU experienced enhanced anxiety, reduced background mood, and impaired quality of life based on general health and mental health scoring scales. The circadian rhythm of melatonin production was markedly distorted throughout the observation period but especially during exacerbations of the disease. Conclusions. The results indicate a high degree of correlation between DU and mental disorders caused by impaired production of melatonin. It suggests common etiological mechanisms of DU and psychosomatic symptom complex.

PERFORATED DUODENAL ULCER ASSOCIATED WITH SITUS INVERSUS AND DEXTROCARDIA

A 32 years old gentleman, presented in emergency department, with complaints of sudden onset of severe upper abdominal pain, associated with nausea and vomiting. He was a known case of acid peptic disease. His abdominal examination showed signs of peritonitis. X-ray chest showed pneumoperitoneum, with dextrocardia. Ultrasound showed situs inversus. Exploration confirmed the diagnosis of perforated ulcer and situs inversus. Grahm's patch repair of perforation was done. His postoperative recovery was smooth.

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.

Reciprocal impact of host factors and Helicobacter pylori genotypes on gastric diseases

AIM: To assess the impact of Helicobacter pylori (H. pylori) genotypes and patient age and sex on the development of gastric diseases.

METHODS: H. pylori-infected patients (n = 233) referred to the endoscopy unit at Tehran University of Medical Sciences (Tehran, Iran) were diagnosed with chronic gastritis (CG), gastric ulcer (GU), or duodenal ulcer (DU). Brucella blood agar was used for biopsy cultures and H. pylori isolation under microaerobic conditions. H. pylori isolates were confirmed with biochemical tests and through amplification of the 16S rRNA gene. DNA was extracted from fresh cultures of the H. pylori isolates and used for amplification of vacA alleles and the cagA gene. Statistical analysis was performed to determine the association between H. pylori genotypes, age (< 40 years vs > 40 years) and sex of the patient, and gastric diseases.

RESULTS: CG was the most prevalent gastric disease (113/233; 48.5%), compared to GU (64/233; 27.5%) and DU (56/233; 24%). More patients were male, and gastric diseases were more frequent in patients > 40 years (P < 0.05). The percentage of CG and GU patients that were male and female did not show a significant difference; however DU was more common in males (P < 0.05). Interestingly, a diagnosis of CG in patients > 40 years was more common in females (18.5%) than males (11.6%) (P = 0.05), whereas a diagnosis of GU or DU in patients > 40 years was more frequent in males (14.6% vs 10.7% and 12.4% vs 4.3%, respectively). Overall, genotyping of the H. pylori isolates revealed that the vacA s1 (82%), vacA m2 (70%), and cagA⁺ (72.5%) alleles were more frequent than vacA s2 (18%), vacA m1 (29.2%), and cagA^- (all P < 0.05). The vacA s1m2cagA⁺ genotype was the most prevalent within the three disease groups. vacA s1m2 frequency was 56.2% with a similar occurrence in all diagnoses, while vacA s1m1 appeared more often in DU patients (33.9%). A genotype of vacA s2m2 occurred in 15% of isolates and was more common in CG patients (21.2%); vacA s2m1 was the least common genotype (3%). The vacA s1 allele was found to be a risk factor for DU, vacA s2 for CG, and vacA s1 and vacA s2 for GU (all P < 0.05). The vacA s2m2 genotype was associated with the development of CG and GU compared to DU (P < 0.05). No correlation was found between vacA m or cagA and gastric diseases.

CONCLUSION: The outcome of H. pylori infection is the result of interaction between bacterial genotypes and the age and sex of infected individuals.

Geographic differences in low-dose aspirin-associated gastroduodenal mucosal injury

Aspirin, even at low doses, has been known to cause upper gastro-intestinal complications, such as gastroduodenal ulcers, despite the definite benefits from its antithrombotic effects. Helicobacter pylori (H. pylori) is major pathogen responsible for gastroduodenal ulcer formation. There have been conflicting results about the potential interaction between these two ulcerogenic factors and the geographic areas involved. In Western countries, the prevalence of gastroduodenal ulcers is consistently higher in H. pylori-positive low-dose aspirin (LDA) users than in H. pylori-negative ones, suggesting that H. pylori infection exacerbates LDA-induced gastroduodenal mucosal injury in these geographic areas. Meanwhile, previous studies from Japan have generally reported a similar prevalence of LDA-induced gastroduodenal mucosal injury regardless of the presence of H. pylori infection, indicating that the infection is not an overall exacerbating factor for drug-induced injury. H. pylori infection could have a synergistic or antagonistic interaction with LDA use in adverse gastroduodenal events depending on gastric acid secretion. It is well-recognized that the net effect of H. pylori infection on gastric acid secretion shows considerable geographic variation at the population level. While gastric acid secretion levels were not decreased and were well-preserved in most patients with H. pylori infection from Western countries, the majority of Japanese patients with H. pylori infection exhibited decreased gastric acid secretion. Such large geographic differences in the net effect of H. pylori infection on gastric acid secretion could be at least partly responsible for the geographically distinct interaction between LDA use and H. pylori infection on adverse gastroduodenal lesions.

[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.

Characteristics of gastric cancer in peptic ulcer patients with Helicobacter pylori infection

AIM: To evaluate the incidence and clinical characteristics of gastric cancer (GC) in peptic ulcer patients with Helicobacter pylori (H. pylori) infection.

METHODS: Between January 2003 and December 2013, the medical records of patients diagnosed with GC were retrospectively reviewed. Those with previous gastric ulcer (GU) and H. pylori infection were assigned to the HpGU-GC group (n = 86) and those with previous duodenal ulcer (DU) disease and H. pylori infection were assigned to the HpDU-GC group (n = 35). The incidence rates of GC in the HpGU-GC and HpDU-GC groups were analyzed. Data on demographics (age, gender, peptic ulcer complications and cancer treatment), GC clinical characteristics [location, pathological diagnosis, differentiation, T stage, Lauren’s classification, atrophy of surrounding mucosa and intestinal metaplasia (IM)], outcome of eradication therapy for H. pylori infection, esophagogastroduodenoscopy number and the duration until GC onset were reviewed. Univariate and multivariate analyses were performed to identify factors influencing GC development. The relative risk of GC was evaluated using a Cox proportional hazards model.

RESULTS: The incidence rates of GC were 3.60% (86/2387) in the HpGU-GC group and 1.66% (35/2098) in the HpDU-GC group. The annual incidence was 0.41% in the HpGU-GC group and 0.11% in the HpDU-GC group. The rates of moderate-to-severe atrophy of the surrounding mucosa and IM were higher in the HpGU-GC group than in the HpDU-GC group (86% vs 34.3%, respectively, and 61.6% vs 14.3%, respectively, P < 0.05). In the univariate analysis, atrophy of surrounding mucosa, IM and eradication therapy for H. pylori infection were significantly associated with the development of GC (P < 0.05). There was no significant difference in the prognosis of GC patients between the HpGU-GC and HpDU-GC groups (P = 0.347). The relative risk of GC development in the HpGU-GC group compared to that of the HpDU-GC group, after correction for age and gender, was 1.71 (95%CI: 1.09-2.70; P = 0.02).

CONCLUSION: GU patients with H. pylori infection had higher GC incidence rates and relative risks. Atrophy of surrounding mucosa, IM and eradication therapy were associated with GC.

[IMPACT OF OPERATIVE INTERVENTION ON DYNAMICS OF THE IMMUNITY INDICES IN AN ACUTE GASTRODUODENAL HEMORRHAGE]

The results of surgical treatment of 39 patients, suffering an acute gastroduodenal ulcer hemorrhage, were analyzed. Gastric ulcer disease was diagnosed in 9 patients, duodenal ulcer disease--in 29, combined ulcer--in 1. A light degree blood loss was noted in 13 patients, while a middle degree--in 12, and severe--in 14. In accordance to J. Forrest classification in 6 patients an active bleeding was revealed (FIa, FIb), in 11--nonstable hemostasis (FIIa, FIIb, FIIc), and in 22--FIII. Preoperatively in patients on the third, seventh and fourteenth day the contents of CD3+, CD4+, CD8+, CD19, calculation of a CD4+/CD8+ ratio, the level of immunoglobulins (IgA, IgM, IgG) and circulating immune complexes were determined in peripheral blood. Phagocytic activity of neutrophils was estimated, using determination of phagocytic index and phagocytic number. In an acute gastroduodenal ulcer hemorrhage immunosuppression was noted, and severity of disorders in T- and B-chains of immunity have depended upon a blood loss severity. Conduction of a routine basic conservative therapy in postoperative period did not guarantee elimination of immunosuppression.

Successful treatment of life-threatening bleeding from a duodenal posterior bulb peptic ulcer by an over-the-scope-clip

Bleeding of peptic ulcer at the posterior duodenal bulb still is a particular endoscopic challenge with increased risk of treatment failure and worse outcome. In this article, we report successful treatment of an actively bleeding peptic ulcer located at the posterior duodenal wall, using an over-the-scope-clip in the case of a 54-year-old male patient with hemorrhagic shock. Incident primary hemostasis was achieved and no adverse events occurred during a follow-up of 60 d.

Valentino appendix: a report of 3 cases

We present three cases of young male patients with perforated duodenal ulcer that were diagnosed and treated as appendicitis with appendectomy. They presented with peritonitis and were treated accordingly. Because of the misdiagnosis, their hospital course was significantly prolonged. This morbidity could have been avoided by careful history-taking, examination and per-operative findings.

Helicobacter pylori infection in patients with selective immunoglobulin E deficiency

AIM: To investigate the prevalence and clinical characteristics of Helicobacter pylori (H. pylori)-infected dyspeptic patients with selective immunoglobulin E deficiency (IgEd).

METHODS: All individuals who underwent serum total immunoglobulin E (IgE) measurement at the Leumit Healthcare Services (Israel) in 2012 were identified in an electronic database search (n = 18487). From these, selected case group subjects were ≥ 12 years of age and had serum total IgE < 2 kIU/L (n = 158). The control group was selected from a random sampling of the remaining subjects ≥ 12 years of age to obtain a case-control ratio of 1:20 (n = 3160). Dyspeptic diseases, diagnosed no more than 5 years before serum total IgE testing, were identified and retrieved from the electronic database using specific International Classification of Diseases diagnostic codes. Results of C¹³-urea breath tests were used to identify subjects infected with H. pylori. Categorical variables between case and control subjects were analyzed using Fisher’s exact tests, whereas continuous variables were analyzed using χ² tests.

RESULTS: Dyspepsia was present in 27.2% (43/158) of case subjects and 22.7% (718/3160) of controls. Of these, significantly more case subjects (32/43, 74.4%) than controls (223/718, 31.1%) were positive for H. pylori (P < 0.01). Esophagogastroduodenoscopy was performed in 19 case and 94 control subjects, revealing that gastritis was more prevalent in IgEd case subjects than in controls (57.9% vs 29.8%, P < 0.05). Furthermore, a significantly greater proportion of case subjects presented with peptic duodenal ulcers (63.2% vs 15.9%, P < 0.01). Histopathologic examination showed marked chronic inflammation, lymphoid follicle formation and prominent germinal centers, with polymorphonuclear cell infiltration of gastric glands, that was similar in case and control biopsy tissues. Finally, IgEd case subjects that underwent esophagogastroduodenoscopy were more likely to exhibit treatment-refractory H. pylori infections that require second-line triple antibiotic therapy (47.4% vs 11.7%, P < 0.01).

CONCLUSION: IgEd is associated with higher rates of H. pylori-associated gastritis and peptic duodenal ulcers.

[REAL-TIME PCR IN THE COMPLEX DIAGNOSTICS OF COMBINED PATHOLOGY OF THE PERIODONTIUM AND GASTRO-DUODENAL ZONE]

Biological material of 92 patients (18-85 years old) with different severity chronic periodontitis were analyzed for bacterial pathogen colonization by using Dentofol kit (DNA-technology, Moscow). The cohort included 70 individuals with chronic gastritis, 2 patients with gastric and duodenal ulceration and 20 individuals with no gastric/duodenal pathology. The tight- est association with severity of the chronic periodontitis in the analyzed sub-cohort with the chronic gastritis was found with the prevalence of a complex T. for sythensis/T. denticola. Key contribution of this complex to progression of periodon- titis in males of the eldest group (above 55) was hypothesized. This data essentially differ from published results of other research groups where T. forsythensis and T. denticola were never reported as the principal causative agents of the chronic periodonitis in the gender/age/combined pathology normalized cohorts.
