The changing face of chronic autoimmune atrophic gastritis: an updated comprehensive perspective.

Autoimmun Rev 2019 Mar 11;18(3):215-222. Epub 2019 Jan 11.

Division of Gastroenterology and Center for Autoimmune Liver Diseases, ASST San Gerardo Hospital, Department of Medicine and Surgery, University of Milan Bicocca, Monza, Italy.

Chronic autoimmune atrophic gastritis (CAAG) is an organ-specific autoimmune disease, which affects the corpus-fundus gastric mucosa. Although it has been described for several years, the real pathophysiological mechanisms, the natural history and the possible neoplastic complications are not completely known. Atrophy of the gastric mucosa is the endpoint of the chronic processes, with the loss of glandular cells and their replacement by intestinal-type epithelium, pyloric-type glands, and fibrous tissue.

The incidence of neoplasia in patients with autoimmune metaplastic atrophic gastritis: a renewed call for surveillance.

Ann Gastroenterol 2019 Jan-Feb;32(1):67-72. Epub 2018 Nov 8.

Division of Gastroenterology (Nadim Mahmud, Bryson W. Katona, David C. Metz).

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

Measurement of Autoantibodies to Gastric H+,K+-ATPase (ATP4A/B) Using a Luciferase Immunoprecipitation System (LIPS).

Methods Mol Biol 2019 ;1901:113-131

Division of Genetics and Cell Biology, IRCCS San Raffaele Scientific Institute, Milan, Italy.

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.

Pernicious anemia associated with cryptogenic cirrhosis: Two case reports and a literature review.

Medicine (Baltimore) 2018 Sep;97(39):e12547

Department of Hepatology, The First Hospital of Jilin University, Jilin University, Changchun, Jilin, China.

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

Hemolytic Anemia and Gastric Carcinoid in a Russian Seafarer: Highlighting the Role of Diagnostic Technologies in Modern Clinical Practice.

Yale J Biol Med 2018 09 21;91(3):243-246. Epub 2018 Sep 21.

Section of General Internal Medicine, Yale School of Medicine, New Haven, CT.

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.

Hematológiai Osztály, Somogy Megyei Kaposi Mór Oktató Kórház Kaposvár, Tallián Gy. u. 20-34., 7400.

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.

CA 15-3 predicting breast cancer relapse: beware of vitamin B12 deficiency.

Per Med 2018 05 10;15(3):163-165. Epub 2018 May 10.

Faculty of Medicine, Department of Hematology-Oncology, Hotel-Dieu de France University Hospital, Saint Joseph University,  Beirut, Lebanon.

A sustained increase of cancer antigen 15-3 serum levels was found in a 54-year-old woman treated 2 years ago for early stage breast cancer, without any evidence of cancer recurrence. The patient thereafter developed severe megaloblastic anemia secondary to vitamin B12 deficiency. Supplementation with B12 to reverse the anemia led to the normalization of the cancer antigen 15-3 serum levels. Read More

Anti-High-Density Lipoprotein Antibodies and Antioxidant Dysfunction in Immune-Driven Diseases.

Front Med (Lausanne) 2018 23;5:114. Epub 2018 Apr 23.

Area of Immunology, Department of Functional Biology, University of Oviedo, Oviedo, Spain.

Introduction: Impaired high-density lipoprotein (HDL) levels and antioxidant functionality of HDL, mainly attributed to a decreased paraoxonase-1 (PON1) functionality, have been described in autoimmune conditions. In this setting, a role for humoral response in cardiovascular disease is emerging. This study evaluates the role of immunoglobulin G (IgG) antibodies against HDL and disease-related autoantibodies on HDL dysfunction in immune-driven diseases. Read More

Laboratory Medicine Center, Affiliated Hospital of Nantong University, Nantong, Jiangsu 226000, P.R. China.

Multiple myeloma (MM), accounting for ~1% of all types of human cancer and 13% of all hematological malignancies, is characterized by the malignant proliferation of monoclonal plasma cells (PCs) in the bone marrow. MM leads to end stage organ impairment, including bone lesions, renal dysfunction, hypercalcemia and anemia. So far, the specific pathogenesis of MM remains unclear and no early-stage sensitive biomarker of MM has been well characterized. Read More

Vitamin B.

Adv Food Nutr Res 2018;83:215-279. Epub 2018 Feb 2.

Department of Nutrition, University of Oslo, Oslo, Norway.

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
