Background: Autoimmune metaplastic atrophic gastritis (AMAG) is an immune-mediated process that may lead to pernicious anemia (PA) and an increased risk of gastric cancer. Although some literature supports 3- or 5-year endoscopic surveillance for gastric cancer in patients with PA, no formal guidance exists for the general AMAG population. We sought to identify the prevalence and incidence rates of dysplasia or adenocarcinoma in patients with AMAG in order to clarify endoscopic best practices. Read More

Background/purpose: Approximately 27% of atrophic glossitis (AG) patients have the serum gastric parietal cell antibody (GPCA) positivity. This study assessed whether the serum GPCA or AG itself was a significant factor causing anemia, hematinic deficiencies, and hyperhomocysteinemia in GPCA-positive AG (GPCAAG) and GPCA-negative AG (GPCAAG) patients.

Methods: The mean corpuscular volume (MCV) and mean blood hemoglobin (Hb), iron, vitamin B12, folic acid, and homocysteine levels were measured and compared between any two of three groups of 284 GPCAAG, 780 GPCAAG patients, and 532 healthy control subjects. Read More

The Luciferase Immuno Precipitation System (LIPS) enables the detection of specific serum antibodies by immunoprecipitation of recombinant antigens tagged with a luciferase reporter. Here we describe LIPS assays for the quantification of autoantibodies to the H+, K+-ATPase A (ATP4A) and B (ATP4B) subunits, two serological markers of autoimmune atrophic gastritis and pernicious anemia. In particular, we will describe the expression of luciferase-tagged recombinant ATP4A and ATP4B, their immunoprecipitation with test sera, the recovery and washing of immune-complexes with a protein-A coated resin, and the quantification of autoantibodies by addition of a luciferase substrate and the measurement of the light output from captured luciferase-tagged antigens.

Introduction The association between type 1 diabetes (T1D) and other auto-immune diseases is well known. However, a quantitative overview of all associated auto-immune diseases and their prevalence in T1D is lacking. Methods We searched PubMed, Web of Science, EMBASE and Cochrane library in September 2018 to identify relevant articles about the prevalence of the following associated auto-immune diseases in T1D cohorts: auto-immune thyroid disease, celiac disease, gastric autoimmunity including pernicious anemia, vitiligo and adrenal gland insufficiency.

Protein-protein interactions (PPIs) perform a very important function in many cellular processes, including signal transduction, post-translational modifications, apoptosis, and cell growth. Deregulation of PPIs results in many diseases, including cancer and pernicious anemia. Although many high-throughput methods have been applied to generate a large amount of PPIs data, they are generally expensive, inefficient and labor-intensive. Read More

Rationale: Pernicious anemia (PA) is an autoimmune gastritis that results from the destruction of gastric parietal cells and the associated lack of an intrinsic factor to bind ingested vitamin B12. While an association between PA and various liver diseases has been rarely reported, reports of associated diseases include primary biliary cholangitis, autoimmune hepatitis, and Interferon-treated hepatitis C. We present 2 cases of PA associated with cryptogenic cirrhosis (CC), which has not been previously reported in the literature. Read More

Vitamin B-12 deficiency, most commonly due to pernicious anemia, can cause intramedullary hemolysis. The pathogenesis is thought to be due to increased membrane rigidity and reduced red blood cell elasticity, which predisposes the patient to hemolysis and microangiopathic hemolytic anemia. In this article, we discuss a Russian engineer who worked aboard a petroleum tanker that presented from his ship with profound B-12 deficiency, microangiopathic anemia, elevated lactate dehydrogenase levels, low haptoglobin, and reticulocyte count in the setting of normal renal and neurologic function.

The bone marrow aspiration, which was done in a leukopenic, hypochromic, microcytic, progressive anemic, thalassemic patient, revealed megaloblastic morphology. The low level of vitamin B and the reticulocytosis following the B supportation strenghtened the diagnosis of pernicious anemia. The set of the right diagnosis has been delayed by the fact that even in severe anemia one could not obtain the typical signs of B deficiency, having a hypochromic, microcytic erythrocyte morphology, due to the thalassemia minor disorder.

The biosynthesis of B, involving up to 30 different enzyme-mediated steps, only occurs in bacteria. Thus, most eukaryotes require an external source of B, and yet the vitamin appears to have only two functions in eukaryotes: as a cofactor for the enzymes methionine synthase and methylmalonylCoA mutase. These two functions are crucial for normal health in humans, and in particular, the formation of methionine is essential for providing methyl groups for over 100 methylation processes. Read More
