Diagnosis, Treatment and Long-Term Management of Vitamin B12 Deficiency in Adults: A Delphi Expert Consensus.

Background/Objectives: Vitamin B12 deficiency can cause variable symptoms, which may be irreversible if not diagnosed and treated in a timely manner. We aimed to develop a widely accepted expert consensus to guide the practice of diagnosing and treating B12 deficiency. Methods: We conducted a scoping review of the literature published in PubMed since January 2003. Data were used to design a two-round Delphi survey to study the level of consensus among 42 experts. Results: The panelists agreed on the need for educational and organizational changes in the current medical practices for diagnosing and treating B12 deficiency. Recognition of clinical symptoms should receive the highest priority in establishing the diagnosis. There is agreement that the serum B12 concentration is useful as a screening marker and methylmalonic acid or homocysteine can support the diagnosis. Patient lifestyle, disease history, and medications can provide clues to the cause of B12 deficiency. Regardless of the cause of the deficiency, initial treatment with parenteral B12 was regarded as the first choice for patients with acute and severe manifestations of B12 deficiency. The use of high-dose oral B12 at different frequencies may be considered for long-term treatment. Prophylactic B12 supplementation should be considered for specific high-risk groups. Conclusions: There is a consensus that clinical symptoms need to receive more attention in establishing the diagnosis of B12 deficiency. B12 laboratory markers can support the diagnosis. The severity of clinical symptoms, the causes of B12 deficiency, and the treatment goals govern decisions regarding the route and dose of B12 therapy.

Individuals Diagnosed With Type 2 Diabetes Mellitus and the Status of Vitamin B12 Deficiency: A Review.

Type 2 diabetes mellitus (T2DM) is a complex metabolic disorder with a multifactorial etiology and a significant global burden. In recent years, emerging evidence has suggested a potential link between T2DM and vitamin B12 deficiency, raising concerns about its impact on disease progression, management, and associated complications. This comprehensive review critically examines the current understanding of the prevalence, risk factors, clinical implications, and management strategies related to vitamin B12 deficiency in individuals diagnosed with T2DM. The review begins by providing an overview of the epidemiology of T2DM and its associated complications, underscoring the need for comprehensive management approaches. Subsequently, it delves into the physiology of vitamin B12, including its sources, absorption mechanisms, and biological functions, laying the groundwork for understanding the potential implications of deficiency in T2DM. A thorough analysis of the literature is conducted to elucidate the prevalence and risk factors of vitamin B12 deficiency in individuals with T2DM, considering factors such as age, duration of diabetes, medication use (e.g., metformin), dietary patterns, and comorbidities. Special attention is given to the role of metformin, the first-line therapy for T2DM, in precipitating or exacerbating vitamin B12 deficiency through mechanisms involving alterations in the gut microbiota and intestinal absorption. The review further explores the clinical manifestations and diagnostic challenges associated with vitamin B12 deficiency in the context of T2DM, emphasizing the importance of recognizing subtle symptoms and implementing appropriate screening protocols. It discusses the potential implications of vitamin B12 deficiency on glycemic control, diabetic neuropathy, cognitive function, cardiovascular health, and overall quality of life in individuals with T2DM. In addressing the management of vitamin B12 deficiency in T2DM, the review examines various therapeutic strategies, including oral and parenteral supplementation, dietary modifications, and lifestyle interventions. It critically evaluates the evidence supporting routine screening for vitamin B12 deficiency in individuals with T2DM and discusses controversies surrounding optimal supplementation protocols, dosing regimens, and monitoring strategies. Furthermore, the review highlights gaps in current knowledge and identifies areas for future research, such as the long-term effects of vitamin B12 supplementation on clinical outcomes in T2DM, the impact of genetic factors on vitamin B12 metabolism, and the potential role of personalized interventions. Overall, this review consolidates existing evidence and provides insights into the complex relationship between T2DM and vitamin B12 deficiency, aiming to inform clinical practice, enhance patient care, and guide future research endeavors in this important area of metabolic medicine.

Management of vitamin B12 deficiency in primary care

Vitamin deficiencies are a major global health concern, and are a particular risk to infants, children and pregnant women. This article discusses what primary care nurses need to know when consulting a patient with a suspected deficiency Vitamin B12 is an essential water-soluble vitamin, which is vital in the production of red blood cells, nervous system function, and DNA synthesis during cell division. Vitamin B12 deficiency is a condition resulted from inadequate intake or malabsorption of vitamin B12. Severe B12 deficiency could lead to pernicious anaemia, mental impairment, and neurological disorders. Therefore, careful management and treatment are pivotal. This deficiency is commonly treated with B12 injections in Primary Care. However, review of literature showed that oral B12 supplementation was as effective as parenteral treatment. To minimise ambiguity in administering B12 injections, several clinical guidelines were highlighted. Nevertheless, further research is needed to evaluate the effectiveness of oral B12 therapy.

‘Closing the loop’: re-audit of the diagnosis and management of vitamin B12 deficiency in general practice

IntroductionVitamin B12 deficiency is common in Ireland, The Irish Longitudinal Study on Aging (TILDA) survey indicates 12% of over 50s in Ireland are low or deficient. The condition is commonly managed exclusively in general practice.AimThe intention of this audit was to establish whether B12 deficiency is diagnosed correctly and whether there was over-treatment of patients.MethodsThe audit was conducted in an urban general practice in midwest Ireland. The primary limitation was the low number of patients. Thirty-five patients were included after practice database searches. An initial audit was performed which compared with the standard, Royal University of Bath: ‘Guidelines for the Investigation & Management of B12 deficiency’.ResultsThe recommendations from this audit were to complete follow-on investigations and to switch over patients from IM to oral replacement. Twenty-one patients were then recalled, and investigations were performed. Ten patients were then switched from IM replacement to oral therapy. A re-audit was then completed. The re-audit showed marked improvement in compliance, from 17% (n = 6) to 83% (n = 29). The reduction in patients on IM therapy will decrease practice burden, with an annual reduction of nurse consultations by 46, representing a 30% decrease in nurse consultations for IM vitamin B12. This equates to an annual cost reduction of €1,340.ConclusionThis closed loop audit demonstrated that there was over treatment and under investigation of patients with B12 deficiency in general practice and that auditing of this process could both reduce risk for patients and save money and time.

Vitamin B12 deficiency in a large cohort of healthcare professionals across the network of an eyecare organization in India.

Purpose:To evaluate Vitamin B12 levels in healthcare professionals at a tertiary eyecare centre in India.Methods:This was a cross-sectional study conducted among healthcare professionals working at a tertiary eyecare centre in India. The sample included 2,374 employees. Chemiluminescent immunoassay method (reference range, 211–911 pg/ml) was used to assess serum vitamin B12 levels. Effect of age and gender was analyzed in vitamin B12 normal and vitamin B12 deficient groups. To evaluate risk factors, questions related to vitamin B12 deficiency were asked to the study participants in a survey.Results:The mean age of employees was 29.2 ± 0.7 years. Around 26% of them were vitamin B12 deficient. The proportion of males in the vitamin B12 deficient group (61.2%) was significantly higher (P < 0.0001) than that of the vitamin B12 normal group (44.9%). There was no effect of age on vitamin B12 levels in both vitamin B12 normal and vitamin B12 deficient groups. Mean vitamin B12 levels in males (289.1 ± 22.2 pg/ml) was significantly lower (P < 0.0001) than that of females (338.7 ± 30.0 pg/ml).Conclusion:This is the first such study on eyecare professionals. One-fourth of the eyecare professionals were vitamin B12 deficient. The proportion of males was higher in the vitamin B12 deficiency group. Males had lower vitamin B12 levels than females. Annual blood tests for vitamin B12 are recommended for timely diagnosis and management of vitamin B12 deficiency, particularly in males.

P77 Management of vitamin B12 deficiency in primary care during the COVID-19 pandemic: Do all patients need to come in?

IntroductionNot all causes of vitamin B12 deficiency require intramuscular hydroxocobalamin (IMH). NICE guidance states that diet-related deficiency can be treated orally, but pernicious anaemia must be excluded via anti-intrinsic factor antibodies (anti-IFAB). Our aim was to audit the management of B12 deficiency during the COVID-19 pandemic when reducing footfall is vital. Then, implement staff education strategies to improve adherence to guidance.MethodsData for patients who received IMH from March-June 2020 was retrospectively analysed for: full blood count (FBC), B12, folate and anti-IFAB levels. These patients were sent letters to have blood tests for the missing investigations. Results were presented at meetings and flowchart-posters were distributed. Audit was closed with prospective data for patients who requested IMH from September-October 2020.ResultsFrom 46 patients identified, 82.6% had B12 and folate checked prior to therapy commencement, but 23.7% had an untreated folate deficiency. 79.3% of patients receiving IMH had never been tested for anti-IFAB; none of those tested were positive. A lack of awareness of the NICE guidance was identified as a key cause for non-adherence. Following the intervention, all 34 patients were appropriately investigated. Out of these, 8.8% had positive anti-IFAB levels and following a review of their clinical histories, all patients were commenced on appropriate therapy.DiscussionIMH can have great benefit; but it is invasive, has financial and nursing-time implications, and increases the risk of contagion via footfall in the practice. Thus, this multi-cycle audit shows that appropriate investigations prior to commencing therapy is key.

Review of Vitamin B12 deficiency in pregnancy: a diagnosis not to miss as veganism and vegetarianism become more prevalent.

Vegetarianism and veganism are increasingly popular. The Food Standards Agency, biennial Food and You Survey of adults aged 16years and over living in the UK, found that between 2012 and 2018 the proportion of people who reported never consuming dairy products had increased from 2% to 5%. However, veganism risks development of vitamin B12 deficiency as it is not available from plant sources. Moreover, its impact may be slow to be detected because body stores of vitamin B12 can last years. There is currently no published guidance on antenatal diagnosis and management of vitamin B12 deficiency. This paper reviews the metabolism, diagnosis and treatment of vitamin B12 in pregnancy. It concludes that national screening policymakers should consider introducing screening for B12 deficiency into the Antenatal and Newborn Screening Programmes for mothers and their infants if at risk of vitamin B12 deficiency. In the interim, national policy should be developed for prophylactic vitamin B12 supplementation in high-risk groups around the time of pregnancy.

Diagnosis &amp; Management of Vitamin B12 Deficiency in Primary Care – Are we following the guidelines?

Background: Vitamin B12 deficiency is common in primary care but its treatment practices vary across centres. One important cause of B12 deficiency is pernicious anaemia (identified by intrinsic factor antibodies), which is a risk factor for developing gastric carcinoma, and should be excluded. Additionally, recent evidence has suggested that some patients have been continued on B12 injections with no clear clinical indication. Recently,guidelines were produced to improve the investigation and management of B12 deficiency. Hence, this audit studied the investigation and management of B12 deficiency and adherence to clinical guidelines in a general practice (GP) in north-west England.Aim: To evaluate the appropriate diagnosis and management of vitamin B12 deficiency in our primary care centre against recognized standards.Methods: Clinical data of patients currently on oral cyanocobalamin and/or intramuscular hydroxocobalamin injections over a 1-year period were audited.Results: Thirty-eight patients (66% females, 34% males) receiving treatment for B12 deficiency were identified. Of these, 55% (21/38) had intrinsic factor antibodies checked and 52% (13/25) were managed according to the guidelines. 100% (8/8) of patients with dietary B12 deficiency (non-vegans) and 75% (3/4) of B12-deficient patients on long-term metformin have had follow-up serum B12 monitoring.Discussion: There is a need to improve the investigation for B12 deficiency, adherence to clinical guidelines, and documentation of patients’ diagnoses, treatment plans, dietary statuses, and required monitoring. We anticipate that adhering to guidelines when appropriate, with clear documentation, will improve the diagnosis and management of vitamin B12 deficiency so that safe prescribing and potential cost savings can be achieved.

Shifts in B12 opinions in primary health care of Sweden

The diagnosis and management of vitamin B12 deficiency varies between countries and within countries. The aim of the study was to map current attitudes and values behind clinical decision-making in Swedish primary health care, which has a unique B12 tradition: two patients out of three are treated with oral high-dose cyanocobalamin. Most patients with B12-associated problems are managed in primary health care by general practitioners (GPs). The study was designed to elucidate possible opinion shifts among GPs during the period 1996-1998. GPs (n=499), stratified and randomized, received a questionnaire with 24 statements on B12-associated clinical and laboratory problems, to be evaluated by a visuo-analogue scale. The majority of GPs in primary health care in Sweden accepted homocysteine and methylmalonic acid (MMA) as markers for functional deficiency of vitamin B12. The evaluation of classical markers of B12 deficiency was wary and balanced. There was a consensus of the need for B12 therapy to risk groups such as patients with atrophic gastritis or previous gastric surgery. The answers also appeared to reflect an improvement of professional knowledge and competence concerning B12-associated problems among Swedish GPs between 1996 and 1998. The overriding conclusion was that B12-associated opinions of Swedish GPs were stable within the period studied, with marginal improvements of knowledge and competence.
