Histological features of nodular gastritis and its endoscopic classification

OBJECTIVES: To clarify the histological features and endoscopic classifications of nodular gastritis (NG). METHODS: Overall 40 996 patients who had undergone an upper gastrointestinal endoscopy were enrolled. NG is defined as a uniform and diffuse protrusion from the antrum to angulus, which has two types at endoscopy: nodular (N) and granular (G). Three biopsy specimens were taken from the antrum, angulus and corpus. The histological features were evaluated using the updated Sydney System (USS). The topography of gastritis (antrum‐predominant, pangastritis or corpus‐predominant) and the prevalence of lymphoid follicles were also investigated. RESULTS: Overall 89 patients (0.22%) were diagnosed with NG, which tended to decrease in prevalence over age and predominantly affected women. All the patients were Helicobacter pylori‐positive. Among these, 65 patients underwent biopsy. Activity and inflammation were mostly moderate or severe, while intestinal metaplasia and atrophy were mostly absent at all three sites. Pangastritis was the most frequent (72%) type of gastritis. Lymphoid follicles were found in 69% at the antrum, 65% at the angulus and 51% at the corpus. There were no significant differences between N and G types in clinical features, USS scores, topography of gastritis, and prevalence of lymphoid follicles. CONCLUSIONS: Atrophy and intestinal metaplasia are rare but activity and chronic inflammation are severe at the antrum, angulus and corpus in NG. Pangastritis is the commonest type of gastritis. Lymphoid follicles affect everything up to the upper corpus, contrary to endoscopic protrusion found only at angulus. There was no correlation with pathological features between N and G types.     

慢性胃炎结节状改变的临床研究

目的 研究萎缩性胃炎和结节性胃炎的结节状改变的特征.方法 在2004年4月至2005年3月之间,通过临床特征、内镜及病理结果,来对比分析胃镜检查中发现的慢性胃炎的结节状改变.结果 本次研究显示慢性胃炎的结节状改变分为结节类型A（结节性胃炎）和B（萎缩性胃炎的结节状改变）.结节性胃炎的胃镜下表现为结节具有大小均一、分布密集的特点,多发生于年轻女性,几乎都以上腹部疼痛为主诉,并且感染了幽门螺杆菌,病理检查有淋巴滤泡而没有萎缩和肠上皮化生.而萎缩性胃炎的结节类型B,胃镜下表现为结节大小不一、分布松散,多发生于50岁以上男性,主诉具有多样性的特点,并且幽门螺杆菌检测部分阴性,病理的结果发现有中、重度萎缩和肠上皮化生,而少有淋巴滤泡.结论 拥有结节状改变类型A的结节性胃炎是一种新的特殊胃炎,不同于萎缩性胃炎的结节状改变,应该引起重视.     

慢性胃炎患者胃内微生物区系的初步研究

用从内镜下取得的胃黏膜标本提取总DNA,随后用16S rDNA的方法进行检测,构建系统进化树。我们共从66个有效序列中发现胃内有5个门的细菌种类,其中H.pylori是最为丰富的细菌种类。在胃内苛刻条件下仍存在除了H.pylori之外的复杂的细菌区系,这为我们进一步研究慢性胃炎的治疗开拓了新的思路。

Endoscopy-based Kyoto classification score of gastritis related to pathological topography of neutrophil activity

BACKGROUND Endoscopy-based Kyoto classification for gastritis and pathological topographic distribution of neutrophil infiltration are correlated with gastric cancer risk.AIM To investigate the association between Kyoto classification and the topographic distribution of neutrophil activity.METHODS Kyoto classification score, ranging from 0 to 8, consisted of atrophy, intestinal metaplasia, enlarged folds, nodularity, and diffuse redness. Neutrophil activity was scored according to the updated Sydney System using biopsy samples obtained from the greater curvature of the corpus and the antrum. The participants were divided into four categories, inactive stomach, antrumpredominant gastritis, pangastritis, and corpus-predominant gastritis, based on the topographic distribution of neutrophil activity. Effects of sex, age, body mass index, drinking habit, smoking habit, family history of gastric cancer, serum Helicobacter pylori(H. pylori) antibody, and Kyoto score on topography of neutrophil infiltration were analyzed.RESULTS A total of 327 patients(comprising 50.7% women, with an average age of 50.2 years) were enrolled in this study. H. pylori infection rate was 82.9% with a mean Kyoto score of 4.63. The Kyoto score was associated with the topographic distribution of neutrophil activity. Kyoto scores were significantly higher in the order of inactive stomach, antrum-predominant gastritis, pangastritis, and corpuspredominant gastritis(3.05, 4.57, 5.21, and 5.96, respectively). Each individual score of endoscopic findings(i.e., atrophy, intestinal metaplasia, enlarged folds, nodularity, and diffuse redness) was correlated with the topographic distribution of neutrophil activity. On multivariate analysis, the Kyoto score, age, and serum H. pylori antibody were independently associated with the topographic distribution of neutrophil activity.CONCLUSION The Kyoto classification score was associated with the topographic distribution of neutrophil activity.

Effects of Sulglycotide on inflammation and epithelial cell turnover in activeHelicobacter pylori + chronic gastritis a pilot study

The effects of Sulglycotide were evaluated in a pilot study of activeH. pylori ⁺ atrophic gastritis. Ten informed patients (mean age 51±13 years) entered a double-blind study. Five received Sulglycotide 400 mg three times a day for one year, the other 5, placebo. At 0, 30, 90, 270, and 360 days of treatment, patients underwent endoscopic examinations with multiple biopsics. Morphometric studies (number of inflammatory cells and percent gland volume), morphologic studies (according to the Sydney system), and flow cytofluorimetry were performed in all cases. Compared to findings in the placebo group, patients treated with Sulglycotide showed a reduced number of inflammatory cells and an increase in gland volume 120 days after treatment. While the difference was not statistically significant, the trend was confirmed by the morphologic patterns. Flow cytofluorimetry revealed an increase in the percentage of cells in the G₂ phase (full maturation) and a parallel drop in the S phase (premitotic synthesis) in the Sulglycotide group only in the first three months. These data would appear to indicate an acceleration of gastric epithelial cell maturation and a decrease in the inflammatory infiltrate under the effect of Sulglycotide.     

Association of the human leukocyte antigen class II alleles with chronic atrophic gastritis and gastric carcinoma in Koreans

OBJECTIVE: Gastric carcinogenesis is a multi‐step process and is influenced by several etiological agents, including the host's genetic factors. Since whether a patient remains with chronic superficial gastritis (CSG) or progresses to either chronic atrophic gastritis (CAG) or gastric carcinoma (GC) could be a genetic predisposition unique in each population, we hypothesized that host human leukocyte antigen (HLA) alleles could be discriminative in predicting the risk of CSG progression to precancerous CAG and GC in Koreans. METHODS: A total of 165 patients with gastric disorders (CSG, 62; CAG, 69 and GC, 34), were selected to investigate the association of HLA class II alleles with the progression of CSG to CAG or GC. HLA genotypes were obtained by the polymerase chain reaction‐sequence based typing method. RESULTS: The phenotypic frequencies of DRB1*1101 and DQA1*0505 were significantly higher in the CAG group compared to those in the CSG group. In the subjects with Helicobacter pylori (H. pypori) (+), the frequencies of DRB1*1501 and DQB1*0602 were significantly lower in the CAG compared to those in the CSG. Further analysis showed that sex (P < 0.05, OR= 0.41–0.42) and age (P < 0.05, OR= 1.05) also affected the risk of progression from CSG to CAG in H. pylori (+) patients carrying the DRB1*1501 or DQB1*0602 allele. Additionally, the frequency of DRB1*0404 in the GC group was significantly higher than that in the gastritis group. CONCLUSION: Our findings strongly imply an association between HLA class II alleles and the risk of CAG development and GC progression in Koreans.     

Serum biomarkers provide an accurate method for diagnosis of atrophic gastritis in a general population: The Kalixanda study

Objective. Serological biomarkers can be used for non-invasive diagnosis of gastritis and atrophic gastritis. The aim of this study was to compare the validity of serum levels of pepsinogen I (PGI) and II (PGII), gastrin-17 (G-17) and Helicobacter pylori antibodies (Hpab) with that of the gold standard histology for diagnosis of atrophic gastritis in a population sample from Northern Sweden. Material and methods. In all, 1000 subjects underwent endoscopies with biopsies. Serum biomarkers were available in 976 subjects for independent diagnosis of gastric mucosal status using a predetermined diagnostic algorithm. Results. Overall agreement between histology and serological biomarkers in diagnosing corpus atrophy was 96% (CI 95%: 95–97%). Sensitivity and specificity of markers for atrophic gastritis were 71% (CI 68–74%) and 98% (CI 97–99%) respectively, corresponding to 69% (CI 95%: 66–72%) and 98% (95% CI 97–99%) positive and negative predictive values. The positive likelihood ratio was 35.5 (95% CI: 35.0–36.0%). In subgroups with normal stomachs, H. pylori non-atrophic gastritis and H. pylori-negative gastritis by histology, the prevalence of corpus atrophy diagnosed with the biomarkers was 0.8% and 4.9%, respectively. In total, 6.6% of subjects in the study population had corpus atrophy according to the serological biomarkers. Conclusions. Serological biomarkers show a high degree of accuracy as a non-invasive method to diagnose corpus atrophy, which is common in the general population.     

Effect of Hewei-Decoction on chronic atrophic gastritis and eradication of Helicobacter pylori

AIM: To demonstrate the effect of Hewei-Decoction (Decoction for regulating the stomach) on chronic atrophic gastritis (CAG) and eradication of Helicobacter pylori. METHODS: Ninety patients with CAG entering the investigation were divided into six differentiation syndromes, based on their major symptoms and signs. Hewei-Decoction was taken by all the patients orally for 4 or 8 wk. The efficacy was assessed by both the composite accumulation of reduced scores of major symptoms and the eradication of H pylori.X2 test was used to compare the efficacy between H pylori-positive and negative cases, and to disclose the relationship between efficacy and eradication of H pylori. RESULTS: In patients with six different syndrome types, the efficacy of Hewei-Decoction was 91.67% (11/12), 92.86% (13/14), 97.22% (35/36), 87.50% (14/16), 75.00% (6/8), 75.00% (3/4) respectively. The rate of highly efficacious was 58.33% (7/12), 50.00% (7/14), 77.78% (28/36), 62.50% (10/16), 12.50% (1/8) and 25.00% (1/4), respectively. The total efficacy was 91.11% (82/90), and the rate of highly efficacious was 60.00% (54/90). The eradication rate of H pylori was 67.86% (38/56). The therapeutic effect of Hewei-Decoction was better in H pylori positive cases than that in H pylori-negative cases with the total effect of 96.43% vs 82.35% (P<0.05). In 56 H pylori positive cases, the therapeutic effect was better in H pylori eradicated cases than that in H pylori-existent cases with the total effect of 97.37% vs 72.22% (P<0.01). CONCLUSION: Hewei-Decoction is effective in most cases of all the syndrome types. The results indicate that eradication of H pylori is one of the important mechanisms for alleviation of symptoms and signs. Also, the decoction is efficacious in H pylori-negative cases.     

Evaluation of endoscopic and histological findings in Helicobacter pylori-positive Japanese young adults

Background and Aim: Many studies have shown that Helicobacter pylori infection is associated with chronic gastritis, peptic ulcers and gastric carcinoma in adults. However, little is known about these associations in the younger population. The aim of this study was to clarify endoscopic and histological findings in H. pylori‐positive young adults. Methods: Two hundred consecutive outpatients younger than 29 years old undergoing esophago‐gastroduodenal endoscopy at four hospitals between 2001 and 2002 were eligible for this study. At endoscopy, three biopsy specimens were obtained from the mid‐antrum, the angulus and the mid‐corpus. Endoscopic and histological interpretations were based on the updated Sydney System. H. pylori infection was determined by histology and serology. Results: The rates of H. pylori infection were 1.2% (1/86) in normal, 95.8% (46/48) in gastritis, 97.8% (45/46) in duodenal ulcers, 100% (17/17) in gastric ulcers, and 100% (3/3) in gastric carcinomas. Endoscopic findings in 112 H. pylori‐positive patients were 25 normal (22.3%), 38 atrophy (33.9%), 18 erosion (16.1%), and 31 nodularity (27.7%). Histological findings of H. pylori‐positive patients in the anturm revealed mononuclear cell and neutrophil infiltration in 100%, and atrophy in 27.7%. Histological findings of H. pylori‐positive patients in the corpus revealed mononuclear cell infiltration in 75%, neutrophil infiltration in 60.7%, and atrophy in 28.6%. Conclusions: The study shows that H. pylori infection is strongly associated with chronic gastritis and peptic ulcers, and that histological corpus gastritis was found with high frequency in Japanese young adults.
