Pernicious Anemia Presenting With Pseudo Thrombotic Microangiopathy and Falsely Elevated B 12 Levels.

J Hematol 2019 Sep 30;8(3):129-131. Epub 2019 Sep 30.

Department of Internal Medicine, John H. Stroger Jr Hospital of Cook County, 1969 West Ogden Avenue, Chicago, IL 60612, USA.

Pseudo thrombotic microangiopathy is a distinct clinical entity that is seen in patients with B12 deficiency. We describe a patient who presented with microangiopathic hemolytic anemia, thrombocytopenia, altered mentation and renal insufficiency. Thrombotic thrombocytopenic purpura was a major concern; however the peripheral blood smear showed hypersegmented neutrophils and the altered mental status as well as renal dysfunction improved with red cell transfusions.

Fallacies of clinical studies on folic acid hazards in subjects with a low vitamin B status.

Crit Rev Toxicol 2020 Feb 31;50(2):177-187. Epub 2020 Mar 31.

Department of Nonclinical Safety, Janssen Research and Development, Beerse, Belgium.

A 2016 plea for revision of the 1 mg/day upper level of folic acid intake prompted us to comprehensively review the 1945-2017 literature on folic acid hazards in subjects with low cyanocobalamin. The concept of folic acid treatment 'masking' the anemia in undiagnosed cyanocobalamin deficiency, thereby delaying the diagnosis of neuropathy, does not account for the dissociation between the deficiency's hematologic and neurologic manifestations. Possible risks of this concept were addressed by 1963-1971 FDA rulings, classifying all folic acid preparations as prescription-only drugs, delivering ≤1 mg daily. Read More

BMJ Case Rep 2020 Mar 24;13(3). Epub 2020 Mar 24.

Department of Medicine, Madigan Army Medical Center, Tacoma, Washington, USA.

Vitamin B deficiency can be caused by a diverse group of aetiologies. One of the less common of these is an autoimmune condition pernicious anaemia, so named after the most common physiological manifestation of B deficiency: anaemia. However, B is also necessary for nervous system function and its depletion can lead to dysfunction of the posterior columns of the spinal cord resulting in subacute combined degeneration (SCD).

Hematology/Oncology, Rochester Regional Health, Rochester, USA.

Thrombotic thrombocytopenic purpura (TTP) can often be life threatening and requires timely diagnosis and prompt initiation of plasmapharesis. Cobalamin deficiency can closely mimic TTP and distinguishing between the two diseases can prove to be a diagnostic challenge. Previously, cobalamin-related pseudo-TTP has been associated with pernicious anemia, dietary insufficiency and hereditary disorders of cobalamin activation. Read More

Discov Med 2019 Nov-Dec;28(155):247-253

Section of Thrombosis and Benign Hematology, The University of Texas M.D. Anderson Cancer Center, Houston, Texas 77030, USA.

Pernicious anemia (PA), the commonest cause of cobalamin deficiency (CD) in the world, is an autoimmune disease of multifactorial origin and is characterized by chronic atrophic gastritis (CAG) and defective absorption of cobalamin from the terminal ileum due to interference by the intrinsic factor (IF) antibodies. PA-related CD is a lengthy process, which if untreated, can lead to irreversible hematological and neurological sequelae. Although safe and effective therapy is available and the management of PA is straightforward, the diagnosis of PA can be extremely difficult to obtain due to myriad and diverse clinical presentations, frequently coexisting diseases, and limitations of currently available diagnostic tests.

Kamalnayan Bajaj Diabetology Research Centre, Diabetes Unit, King Edward Memorial Hospital Research Centre, Rasta Peth, Pune, India,

Vitamin B12 is a fascinating nutrient in that it is made by microbes but is essential for human metabolism. Humans can get it only from animal origin foods. Dietary deficiency rather than an absorption defect (Pernicious anemia, intrinsic factor defect) is the commonest cause of deficiency in the world, contributed by cultural and economic imperatives.

Thyro-entero-gastric autoimmunity: Pathophysiology and implications for patient management.

Best Pract Res Clin Endocrinol Metab 2019 Dec 11:101373. Epub 2019 Dec 11.

Department of Medico-Surgical Sciences and Biotechnologies, Sapienza University of Rome, Viale Policlinico 155, 00161, Rome, Italy.

The association between autoimmune atrophic gastritis and thyroid disorders has been observed since the early 1960s and the expression "thyrogastric syndrome" was coined to indicate the presence of thyroid autoantibodies or autoimmune thyroid disease in patients with pernicious anemia, a late clinical stage of autoimmune atrophic gastritis. More recently, it was confirmed that autoimmune thyroid disorders, in particular Hashimoto's thyroiditis, may be frequently associated with other organ-specific, immune-mediated disorders, such as autoimmune atrophic gastritis or celiac disease. The association of Hashimoto's thyroiditis with autoimmune atrophic gastritis or celiac disease in adult patients is currently considered part of the polyglandular autoimmune syndromes which include several autoimmune disorders associated with an autoaggressive impairment of endocrine glands.

FMF Is Associated With a Wide Spectrum of MHC Class I- and Allied SpA Disorders but Not With Classical MHC Class II-Associated Autoimmune Disease: Insights From a Large Cohort Study.

Front Immunol 2019 26;10:2733. Epub 2019 Nov 26.

Department of Medicine B and Zabludowicz Center for Autoimmune Diseases, Sheba Medical Center, Ramat Gan, Israel.

To test the hypothesis that familial Mediterranean fever (FMF)-associated autoinflammation may exaggerate the tendency toward adaptive immunopathology or spondyloarthritis (SpA)-associated disorders including major histocompatibility complex (MHC) class I associated disorders but not classical MHC class II-associated disorders that exhibit transplacental autoimmunity including myasthenia gravis and pemphigus. Seven thousand seven hundred forty-seven FMF patients and 10,080 age- and sex-matched controls in the Clalit Health Services medical database were identified and compared in terms of prevalence of SpA-associated disorders. We also evaluated four classical and strong MHC class II-associated disorders, namely, pemphigus vulgaris, myasthenia gravis, sarcoidosis, and pernicious anemia, to ascertain whether such associations with SpA-spectrum disease were specific or merely reflected the non-specific consequences of innate immune system activation on driving divergent types of immunity.

Medical Research Council Lifecourse Epidemiology Unit, University of Southampton, Southampton, United Kingdom.

Background: Vitamin B-12 deficiency is often considered synonymous with pernicious anemia, a rare condition in which severe malabsorption of the vitamin requires high-dose parenteral treatment. In developing countries such as India, inadequate dietary intake of B-12 due to socio-cultural factors leads to widely prevalent asymptomatic low B-12 status. In this scenario, lower doses of oral B-12 may be effective, safer and more affordable. Read More

[A Case of Suspected Nonparaneoplastic Autoimmune Panencephalitis with Widespread Multifocal Brain Lesions and Treatable Dementia Following Pernicious Anemia: A Seven Year Follow-Up Study].

Brain Nerve 2019 Sep;71(9):1003-1012

Department of Neurology, Saiseikai Matsusaka General Hospital.

We present a case of a 73-year-old female who developed subacute memory disturbance, reduced consciousness and quadriparesis following pernicious anemia. Brain magnetic resonance imagings (MRI) in diffusion weighted, T2 weighted and fluid attenuated inversion recovery (FLAIR) images revealed hyperintensities in bilateral frontal, parietal, temporal and occipital cortices, left thalamus, bilateral splenium of corpus callosum, and bilateral subcortical white matters. Brain gadolinium enhanced T1 weighted MRI revealed very slight post-contrast enhancement lesions in the right posterior temporal region and bilateral parietal regions. Read More

Pernicious Anemia Presenting as Non-ST-elevated Myocardial Infarction and Depression.

Cureus 2019 Jun 10;11(6):e4870. Epub 2019 Jun 10.

Internal Medicine, St. Francis Medical Center, Seton Hall University, Trenton, USA.

Pernicious anemia (PA) is a common cause of megaloblastic anemia throughout the world, especially in Northern European whites. This disease is characterized by the deficiency of vitamin B12 due to the presence of anti-intrinsic factor and anti-parietal cell antibodies which inhibit the absorption of the vitamin B12. In cases of severe vitamin B12 deficiency, patients can suffer debilitating complications such as described in our case. Read More

Gut 2019 09 5;68(9):1545-1575. Epub 2019 Jul 5.

Gastroenterology, IPO Porto, Porto, Portugal.

Gastric adenocarcinoma carries a poor prognosis, in part due to the late stage of diagnosis. Risk factors include infection, family history of gastric cancer-in particular, hereditary diffuse gastric cancer and pernicious anaemia. The stages in the progression to cancer include chronic gastritis, gastric atrophy (GA), gastric intestinal metaplasia (GIM) and dysplasia. Read More

Pernicious anemia: a myelodysplastic syndrome look-alike.

J Community Hosp Intern Med Perspect 2019 19;9(3):240-243. Epub 2019 Jun 19.

Hematology, Riverside University Health System Medical Center, Moreno Valley, CA, USA.

Severe cytopenias (anemia, thrombocytopenia, neutropenia or any combination of these) are common causes of ER visits and hospital admissions. In adults, the etiology of cytopenias has a broad differential diagnosis including vitamin and mineral deficiencies, autoimmune conditions, infections, bone marrow failure disorders, or malignancies. We present a case of severe anemia and thrombocytopenia who was initially diagnosed with myelodysplastic syndrome (MDS) based on the results of a bone marrow biopsy. Read More
