What are the complications of chronic and acute gastritis? The complications of chronic gastritis may include In most cases, acute gastritis does not lead to complications. Abstract Prevalence of chronic gastritis has markedly declined in developed populations during the past decades. However, chronic gastritis is still one of the most common serious pandemic infections with such severe killing sequelae as peptic ulcer or gastric cancer.
Globally, on average, even more than half of people may have a chronic gastritis at present. Helicobacter pylori infection in childhood is the main cause of chronic gastritiswhich microbial origin is the key for the understanding of the bizarre epidemiology and course of the disease.
A life-long and aggressive inflammation in gastritis results in destruction atrophic gastritis of stomach mucosa with time years and decades. The progressive worsening of atrophic gastritis results subsequently in dysfunctions of stomach mucosa. Atrophic gastritis will finally end up in a permanently acid-free stomach in the most extreme cases. Severe atrophic gastritis and acid-free stomach are the highest independent risk conditions for gastric cancer known so far.
In addition to the risks of malignancy and peptic ulcer, acid-free stomach and severe forms of atrophic gastritis may associate with failures in absorption of essential vitamins, like vitamin B12, micronutrients like iron, calcium, magnesium and zincdiet and medicines.
Prevalence of chronic gastritis has markedly declined in developed populations during the past decades. Gastritis –inflammation of the stomach–is a frequently cited differential yet rarely characterized diagnosis in cases of canine anorexia and vomiting. Although the list of rule-outs for acute or chronic gastritis is extensive, a review of the veterinary literature reveals fewer than 15 articles that have focused on clinical cases of canine gastritis over the last 25 years.
The dog frequently appears in the human literature as an gasrtitis manipulated model for the study of endoscopic techniques or the effect of medications on gastric mucosa.
Gastritis, Chronic, Erosive – NORD (National Organization for Rare Disorders)
In the veterinary patient, cases of acute gastritis are rarely pursued with the complete diagnostic armamentarium, and cases of chronic gastritis are rarely found to occur as an entity isolated from the rest of the gastrointestinal tract.
This article focuses on those findings most clinically relevant to cases of canine gastritis in veterinary medicine. However, loss of parietal cells reduces secretion of gastric acid which is also required for absorption of inorganic iron; thus, iron deficiency is commonly found in patients with autoimmune gastritis. Patients with chronic iron deficiency, especially those refractory to oral iron therapy, should therefore be evaluated for the presence of autoimmune gastritis.
In the present paper, we report a case of rare collagenous gastritis. The patient was a year-old man who had experienced nausea, abdominal distention and epigastralgia since Esophagogastroduodenoscopy EGD carried out at initial examination by the patient’s local doctor revealed an extensively discolored depression from the upper gastric body to the lower gastric body, mainly including the greater curvature, accompanied by residual mucosa with multiple islands and nodularity with a cobblestone appearance.
Initial biopsies sampled from the nodules and accompanying atrophic mucosa were diagnosed as chronic gastritis. In August,the patient was referred to Tohoku University Hospital for observation and treatment. EGD at our hospital showed the same findings as those by the patient’s local doctor. Pathological findings included a membranous collagen band in the superficial layer area of the gastric mucosa, which led to a diagnosis of collagenous gastritis.
Collagenous gastritis is an extremely rare disease, but it is important to recognize its characteristic endoscopic findings to make a diagnosis.
Gastritis is defined as inflammation of the gastric mucosa. In histological terms, it is distinguishable into two main categories, i. In the gastric mucosa, atrophy is defined as the loss of appropriate glands. There are several etiological types of gastritistheir different etiology being related to different clinical manifestations and pathological features.
Atrophic gastritis resulting mainly from long-standing Helicobacter pylori infection is a major risk factor for the onset of intestinal type gastric cancer. The extent and site of the atrophic changes correlate significantly with the cancer risk.
The current format for histology reporting in cases of gastritis fails to establish an immediate link between gastritis phenotype and risk of malignancy. The aim of this tutorial is to provide unequivocal information on how to standardize histology reports on gastritis in gastrittis practice.

Chronic gastritis gastrtis an update. Helicobacter pylori is the main aetiologic factor for chronic gastritis worldwide. The degree of inflammation and the evolution of this form of chronic gastritis can vary largely depending on bacterial virulence factors, host susceptibility factors and environmental conditions.
Autoimmune gastritis is another cause of chronic inflammation in the stomach, which can occur in all age groups. This disease presents typically with vitamin B12 deficiency and pernicious anaemia. The presence of anti-parietal cell antibodies is highly specific for the diagnosis.
The role of H. Other rare conditions for chronic gastritis are chronic inflammatory conditions such as Crohn’s disease or on the background of lymphocytic or collagenous gastroenteropathies.
Published by Elsevier Ltd. Alterations of the stomach mucosa in response to different adverse effects result in various morphological and clinical symptoms. Gastric mucosa alterations can be classified on the bases of diverse viewpoints. It makes this overview difficult, that identical toxic effects may cause different mucosal changes and different toxic agents may produce similar mucosal appearance.
The more accurate understanding of the pathological processes which develop in the stomach mucosa needs reconsideration. The authors make an attempt to define gastritis and gastropathy in order to classify and present their features. Gastritis is a histological definition indicating mucosal inflammation. Acute gastritis is caused by infections. The two most important forms of chronic gastritis are metaplastic atrophic gastritis with an autoimmune origin and Helicobacter pylori inflammation.
Gastropathy is the name of different structural alterations of the mucosa. Its most important feature is the paucity of inflammatory signs. Gastropathies can be divided into 4 categories based on the nature of the underlying pathological effect, on its morphological appearance and the way of the development. Differential diagnosis is an important pathological and clinical task because different treatment methods and prognosis.
Western countries are seeing a constant decline in the incidence of Helicobacter pylori-associated gastritiscoupled with a rising epidemiological and clinical impact of autoimmune gastritis.
This latter gastropathy is due to autoimmune aggression targeting parietal cells through a complex interaction of auto-antibodies against the parietal cell proton pump and intrinsic factor, and sensitized T cells.
Given the specific target of this aggression, autoimmune gastritis is typically restricted to the gastric corpus-fundus mucosa. In advanced cases, the oxyntic epithelia are replaced by atrophic and metaplastic mucosa, creating the phenotypic background in which both gastric neuroendocrine tumors and intestinal-type adenocarcinomas may develop.
Despite improvements in our understanding of the phenotypic changes or cascades occurring in this autoimmune setting, no reliable biomarkers are available for identifying patients at higher risk of developing a gastric neoplasm. The standardization of autoimmune gastritis histology reports and classifications in diagnostic practice is a prerequisite for implementing definitive secondary prevention strategies based on multidisciplinary diagnostic approaches integrating endoscopy, serology, histology and molecular profiling.
Serum Gastrin in Chronic Gastritis. Fasting gastrin levels in serum were measured in 49 patients with different types of chronic gastritis and in matched controls. The mechanism of the raised gastrin levels remains uncertain, but neither achlorhydria nor in vivo action of the parietal cell antibody wholly accounted for the hypergastrinaemia. We conclude that hypergastrinaemia is characteristic of gastritis associated with autoimmune reactions to gastric antigens and pernicious anaemia and that a raised serum gastrin is a useful marker of the type of gastritis that tends to progress to the gastric lesion of pernicious anaemia.
We studied 20 patients in which a variety of erosive gastritis is described. We named it petechial erosive gastritis. We have to bring up that its sequence is due to the presence of the petechiae in the center of the mucosal area.
Then in degrees of higher intensity erosions occur also at the center of the area mucosa. Occasionally the erosions meet, become larger and may bleed. An endoscopic classification of petechial erosive gastritis is established it rates mild, moderate, severe and hemorrhagic degrees. Even if the histopathologic study does not keep a strict correspondence with the severity of endoscopic observation of the lesions, it is possible to separate easily a petechial stage from an erosive stage.
Demonstration of these lesions at their sequence from petechial to bleeding erosion constitutes an important contribution to the study of acute gastric lesions and it might open a way to a better study of the alterations of the irrigation of the gastric mucosa and the etiology of erosive lesions and acute ulcer. Clinicopathologic Findings and Comparison with Helicobacter pylori-associated Gastritis.
The aims of this study were to evaluate the clinicopathologic features of Helicobacter heilmannii-associated gastritis and to compare H. We reviewed 5, consecutive gastric biopsy specimens. All cases of chronic gastritis with Helicobacter infection were evaluated with the Updated Sydney System, and the grades of all gastritis variables were compared between H.
There were 10 cases of H. The organisms were superficially located within the mucous layer without adhesion to epithelial cells.
Interestingly, in one case many intracytoplasmic H. In conclusion, we present the detailed clinicopathologic findings of H. Superoxide dismutases in chronic gastritis. Erosiff gastric diseases have shown significant changes in the activity and gastditis of superoxide dismutase SOD isoforms.
The aim of this study was sdalah detect Mn-SOD activity and expression in the tissue of gastric mucosa, primarily in chronic gastritis immunohistochemical Helicobacter pylori-negative gastritiswithout other pathohistological changes and to evaluate their possible connection with pathohistological diagnosis.
We examined 51 consecutive outpatients undergoing endoscopy for upper gastrointestinal symptoms. Patients were classified based on their histopathological examinations and divided into three groups: Severity of gastritis was graded according to the updated Sydney system.
The Mn-SOD expression was more frequently present in specimens with severe and moderate inflammation of gastric mucosa than in those with normal mucosa. In patients with normal histological finding, positive immunoreactivity of Mn-SOD was not found.
Our results determine the changes in Mn-SOD expression occurring in the normal gastric mucosa that had undergone changes in the intensity of chronic inflammatory infiltrates in the lamina propria. Gastritis in patients undergoing sleeve gastrectomy. Abstract Laparoscopic sleeve gastrectomy LSG is a therapeutic option in severely obese patients.
Pediatric gastritis and peptic ulcer disease.
The aim of this study was to evaluate the presence of Helicobacter pylori HP gastritis and non-Helicobacter gastritis in the gastrectomy specimens, and its association to other variables.
Gxstritis hundred six sleeve gastrectomy specimens were examined histopathologically for the presence of gastritis and its relation to other factors like ethnicity, glycemic control, and postoperative complications. Twelve patients had HP gastritis39 had non-HP gastritisand 55 had normal mucosa. There was gastfitis statistical difference between the Arab and Jewish Israeli patients in our study.
