Abstract Gastric polyps are often present in the setting of atrophic gastritis. Although the majority of these polyps are nonneoplastic, such as hyperplastic polyps, neoplastic polyps may be present.[ncbi.nlm.nih.gov]
BACKGROUND: Autoimmune gastritis may present as pernicious anaemia arising from vitamin B12 malabsorption, but also with iron deficiency anaemia due to iron malabsorption. These different clinical presentations might have a genetic basis.[ncbi.nlm.nih.gov]
Case Report A 24-year-old male patient presented with a history of lethargy and easy fatigability for about four months.[casereports.in]
Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present.[ncbi.nlm.nih.gov]
Autoimmune gastritis presents an age-dependent frequency in children and adolescents with T1D but is rarely symptomatic.[ncbi.nlm.nih.gov]
There was symptomatic improvement in her signs of fatigue.[ncbi.nlm.nih.gov]

Symptoms such as fatigue, hair loss and restless legs syndrome decrease quality of life; furthermore it results in impaired physical and cognitive development and poor pregnancy outcome.[thieme-connect.com]
We ask about general symptoms (anxious mood, depressed mood, fatigue, pain, and stress) regardless of condition. Last updated: July 15, 2019[patientslikeme.com]
As AIG is associated with other autoimmune diseases, symptoms such as fatigue may also be due to thyroid hypofunction in the presence of autoimmune thyroiditis (Hashimoto’s disease).[ncbi.nlm.nih.gov]
Where appropriate, patients underwent radioiodine uptake and scintigraphic mapping, ultrasonography-assisted fine needle aspiration biopsy, and a thyrotropin-releasing hormone test for serial thyrotropin measurements and detection of anti–thyrotropin[jamanetwork.com]
Simple intragastric pH measurement during gastroscopy from aspirates would be quick and cheap, but concerns have been raised that this does not reflect gastric acid secretion or volume of acid secretion [ 34 , 36 ].[ncbi.nlm.nih.gov]

Histamine excess can cause diarrhea as can bacterial overgrowth or LC. We present a 57-year-old woman with diarrhea, sporadic epigastric pain, and bloating.[ncbi.nlm.nih.gov]
Patients referring with non-specific abdominal symptoms such as bloating, diarrhea and iron/B(12) deficiency should be investigated for the presence of AIG. Copyright 2012 S. Karger AG, Basel.[ncbi.nlm.nih.gov]
The patients (seven women, two men, mean age 64 years) presented with nonspecific abdominal or reflux symptoms (n 8) and diarrhea (n 1).[ncbi.nlm.nih.gov]
The presence and the frequency of GI symptoms (heartburn, regurgitation, early satiety, nausea, vomiting, postprandial fullness, epigastric pain, abdominal pain, constipation, diarrhea, and bloating) were assessed at the time of the first visit through[journals.lww.com]
There is a close relationship between autonomic nervous system dysfunction and delayedgastricemptying.[ncbi.nlm.nih.gov]
Autoimmune gastritis is an important etiology to explain the finding of delayedgastricemptying on a radionuclide test.[ncbi.nlm.nih.gov]
OBJECTIVES: Patients with autoimmune gastritis may have symptoms suggestive of delayedgastricemptying.[ncbi.nlm.nih.gov]
Achlorhydria itself leads to symptoms such as delayedgastricemptying, small intestinal (and gastric) bacterial overgrowth, and an increase in GI infections such as clostridium difficile colitis.[ncbi.nlm.nih.gov]
Anemia (irrespective of etiology) results in shortness of breath, dizziness, tachycardia, lightheadedness, and decreased cognitive and physical function. In pregnancy it can lead to poor pregnancy outcome with early birth and underweight newborns.[ncbi.nlm.nih.gov]
Eighteen months later, however, pancreatic insufficiency occurred due to thrombosis of the pancreatic graft. Besides these conditions, iron deficiency, pernicious anemia, and autoimmune gastritis were also diagnosed.[ncbi.nlm.nih.gov]
[…] peripheral smear may mimic other more serious conditions, such as disseminated intravascular coagulopathy (DIC) or thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS). 65 Cobalamin deficiencies have been associated with increased risk of thrombosis[dovepress.com]
Hair loss and brittle nails were seen in about half of patients, sleeping disorder in 36.9% and restlesslegssyndrome in 24.7%.[thieme-connect.com]
Symptoms of iron deficiency arise independently of and prior to anemia-related symptoms, and include fatigue, restlesslegssyndrome, brittle nails, hair loss, impaired immune function, and impaired wound healing.[ncbi.nlm.nih.gov]
She had no history of ulcers, renalimpairment or carcinoid syndrome. Fasting serum gastrin was 1846pg/ml. Esophagoduodenal gastroscopy and biopsies revealed chronic gastritis and a pH of 7 with low stomach acid.[ncbi.nlm.nih.gov]

Discussion and Conclusions In the cases reported here, AIG was a late and unexpected discovery in the diagnostic workup of a refractory anemia.[frontiersin.org]
Laboratory workup All patients had a complete blood count, serum iron, total iron-binding capacity (TIBC), serum ferritin, serum B 12 and folate, sedimentation rate, fibrinogen, and CRP studies performed.[bloodjournal.org]
From a clinical standpoint, the presence of iron-deficient anemia and thyroxine malabsorption may represent an alert signal for the presence of a gastric disorder in patients with thyroid autoimmunity and should trigger a specific diagnostic workup.[frontiersin.org]
Of the 83 subjects with microcyticanemia, only 18 (22%) were men compared with 35 of 77 (46%) for all other groups combined (χ 2 0.0001).[bloodjournal.org]
As expected, the prevalence of microcyticanemia decreased whereas that of macrocytic PA increased with increasing age of patients (data not shown).[jamanetwork.com]
The study of Hershko et al. has also shown a high prevalence of H. pylori positivity in young patients with AIG and microcyticanemia.[frontiersin.org]
In a study by Hershko et al[ 24 ] low serum vitamin B12 levels were found in 100% macrocytic, 92% normocytic and 46% microcytic patients with CAAG, whereas iron deficiency was found in all the patients with microcyticanemia, but also in 50% of the normocytic[wjgnet.com]
Microcyticanemia, the expression of iron deficiency, is a common presenting sign and is caused by achlorhydria, which impairs iron absorption[ 13 ].[wjgnet.com]

Pernicious anemia (PA), the macrocyticanemia also termed as Biermers disease or Addisonian anemia is an autoimmune disorder.[casereports.in]
In 10 of these 12 patients, the macrocyticanemia met the criteria of PA; all of these patients belonged to the group with ABG.[jamanetwork.com]
Besides loss of iron, decreased iron absorption is causative of iron deficiency. This might be due to inflammation at the site of iron uptake, which is found in Crohn’s disease and also coeliac disease.[ncbi.nlm.nih.gov]
Peripheral blood smear showed erythropenia, macrocytic normochromic red blood cells, moderate aniso-poikilocytosis with good number of macro-ovalocytes, leucocytopenia and mild thrombocytopenia, features consistent with pancytopenia and macrocytic anemia[casereports.in]
Compared to NGB, HPG, MAG and CG, AIG displayed more eosinophil infiltration (p 0.001) and more frequent lymphocyteinfiltration of the epithelium, basal predominant inflammation and pancreatic acinar metaplasia (all p 0.05).[ncbi.nlm.nih.gov]
In addition, the typical parameters for this type of gastritis, such as grade of the periglandular lymphocyticinfiltration, grade of glandular destruction and incidence of nodular ECL cell proliferates in the corpus mucosa were determined.[ncbi.nlm.nih.gov]
Autoimmune gastritis is characterised by lymphocyticinfiltration of the gastric submucosa, with loss of parietal and chief cells and achlorhydria.[ncbi.nlm.nih.gov]
Case history of a 21-year-old man with active autoimmune gastritis of the oxyntic mucosa with lymphocyticinfiltration of the entire lamina propria, foci of lymphocytic destruction of a number of glands, and hypertrophy of the preserved parietal cells[ncbi.nlm.nih.gov]
A retrospective study of biopsy specimens from 40 patients was performed; all of the patients were originally diagnosed with possible AG based on the presence of lymphocyticinfiltration and damage to oxyntic glands and/or the presence of metaplastic[ncbi.nlm.nih.gov]
CONCLUSION: As explored with modern DNA-based methods, HLA-DRB1*04 and DQB1*03 alleles, but not HLA-B8-DRB1*03, may predispose to AIG.[ncbi.nlm.nih.gov]
RESULTS: After 1 and 3 months of treatment, mean hemoglobin in group A increased from 9.5 /- 1.2 to 11.2 /- 1.3 and 12.8 /- 1.3 g/dl, respectively.[ncbi.nlm.nih.gov]
