A Brief Review on Vitamin B 12 Deficiency Looking at Some Case Study Reports in Adults. Int J Mol Sci 2021; 22:ijms22189694. [PMID: 34575856 PMCID: PMC8471716 DOI: 10.3390/ijms22189694] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 08/28/2021] [Accepted: 09/04/2021] [Indexed: 11/16/2022] Open
Abstract
In the era of evidence-based medicine, the randomized clinical trial corresponds to the top step in the qualitative scale of the evidence available in the literature, while small series of cases or the description of individual cases occupy the last place. However, the latter represent an important part of clinical practice and have significantly influenced the evolution of medicine, contributing significantly to the advancement of scientific knowledge. Vitamin B12 deficiency shares several common symptoms that affect several tissues and organs with health aliments, so its diagnosis could be unobvious for the broad array of its effects and investigation methods used. In this review, we focused our attention on some case reports related to the vitamin B12 deficiency associated to anemia, neurologic disorders, and hyperhomocysteinemia. B12 deficiency reversal is simply achieved by prompt therapy, even though it is not the same for several disorders.

Abstract
Pernicious anemia (also known as Biermer's disease) is an autoimmune atrophic gastritis which predominantly affects the fundus of the stomach. It results in a deficiency of vitamin B12 (cobalamin) as it affects the normal process of absorption in the ileum. The pernicious anemia is characterized by a wide range of hematological and neurological features. Neurological features can present without hematological manifestations. One of the early neurological features of this anemia is nominal dysphasia (word-finding difficulties), which was usually not reported before as an isolated finding. We present a case of pernicious anemia with isolated nominal dysphasia responding dramatically to parenteral vitamin B12 therapy.

Abstract
Metabolic and deficiency neuropathies retain a growing interest because of their important prevalence. The dismemberment of diabetic neuropathies is proceeded, letting distinct pathophysiological mechanisms appear. So, even if glycaemic control remains determining for preventing the neuropathy associated with type 1 diabetes, it seems to have a restricted role with type 2 diabetes in which other metabolic factors are involved. The diagnosis of neuropathy due to B12 vitamin deficiency remains a real challenge for the clinician. Indeed, positive and negative predictive values of serum B12 and metabolites assay are weak, only a good therapeutic response allows a reliable diagnostic. It is so recommended to know the clinical and contextual particularities of this etiology in order to not delay the vitamin substitution, determining for the functional outcome. Finally, copper deficiency remains an unknown cause of neuropathy which is suitable to raise in case of malabsorption but also and especially in case of abuse of dental adhesive rich in zinc.

Abstract
Neurological disorders related to vitamin B12 deficiency are common in prisons of tropical Africa. We collected 22 cases (20 men and 2 women). They all showed vitamin B12 deficiency associated with neurological signs that were represented by sclerosis combined with bone marrow (n = 9), peripheral neuropathy (n = 6), cerebellar syndrome (n = 2), a pyramidal syndrome of the lower limbs (n = 4) and optic neuropathy (n = 1). Laboratory tests showed a mean hemoglobin concentration of 7.2 ± 1.5 g/dl, mean 104 ± 28 fl, macrocytic anemia in 10 patients. Biermer's disease was identified in 9 patients, 3 patients showed the syndrome of non dissociation of vitamin B12, a gastrectomy in 2 patients and no etiology was identified in 8 patients.

Abstract
Pernicious anemia (also known as Biermer's disease) is an autoimmune atrophic gastritis, predominantly of the fundus, and is responsible for a deficiency in vitamin B12 (cobalamin) due to its malabsorption. Its prevalence is 0.1% in the general population and 1.9% in subjects over the age of 60 years. Pernicious anemia represents 20%-50% of the causes of vitamin B12 deficiency in adults. Given its polymorphism and broad spectrum of clinical manifestations, pernicious anemia is a great pretender. Its diagnosis must therefore be evoked and considered in the presence of neurological and hematological manifestations of undetermined origin. Biologically, it is characterized by the presence of anti-intrinsic factor antibodies. Treatment is based on the administration of parenteral vitamin B12, although other routes of administration (eg, oral) are currently under study. In the present update, these various aspects are discussed with special emphasis on data of interest to the clinician.

Abstract
INTRODUCTION Vitamin B12 deficiency is a longstanding public health problem which affects more than 20% of the elderly population. Among multiple causes of vitamin B12 deficiency, Biermer's disease is currently mentioned in about 25% of the cases. OBSERVATION We report the case of a 71-year-old woman, taking folate substitution therapy who, over 2 years, progressively developed spinal combined sclerosis, subacute dementia and severe neuropathy leading to a bedridden state. The initial assessment revealed normocytic anemia, without vitamin B12 deficiency and without increased plasma level of biological markers. The plasma folate level was high. Vitamin B12 assay was repeated leading to the diagnosis of deficiency associated with the presence of intrinsic factor antibodies. DISCUSSION This observation illustrates the broad spectrum of clinical presentations of vitamin B12 deficiency. In the present case, the lack of sensitivity of biological markers delayed diagnosis and had a dramatic impact on outcome. This case highlights the importance of promoting factors such as isolated folate substitution in B12 deficient patients.
