Introduction: The prevalence of vitamin B12 deficiency is common (around 40%) in people older than 65 years of age and in people who are strict vegetarians. The major sources of Viamin B12 are meat, fish, dairy products and fortified cereals. Aim: To study the prevalence and common types of presentations of vitamin B12 deficiency among 20-80 years aged, non-vegetarian people attending a tertiary care hospital in a state of Eastern India. Materials and Methods: This hospital based cross-sectional study was conducted at IPGME&R and SSKM Hospital between July 2018 to December 2019. Serum samples were collected from 478 adult patients presenting with different symptoms like pallor, fatigue, numbness and tingling sensation in limbs, memory loss, alopecia etc., which may be related to vitamin B12 deficiency. These samples were screened for serum vitamin B12 level by chemiluminescence method in ADVIA, Centaur CP (SIEMENS). Data were analysed statistically by graph pad prism 8 software. Significance of the difference between means were detected using Student’s unpaired t-test and calculating the p-value (p-value <0.05 were considered as significant). Results: Among 184 females, 50 (27.17%) were found to be Vitamin B12 deficient (VBD). Among them, 18 (36%) had mild deficiency (serum vitamin B12 level 201-220 pmol/L), 22 (44%) had moderate (serum vitamin B12 level 150-200 pmol/L) and 10 (20%) had severe deficiency (serum vitamin B12 level <150 pmol/L). A total of 35 (70%) of the VBD females were of <50 years of age. Among 294 males, 83 (28.23%) were found to be VBD. Among them, 34 (41%) had mild deficiency (serum vitamin B12 level 201-220 pmol/L), 36 (43%) had moderate (serum vitamin B12 level 150-200 pmol/L) and 13 (16%) had severe deficiency (serum vitamin B12 level <150 pmol/L). Total 43 (51.8%) of VBD male persons were of <50 years age. Among VBD female patients, 24 (48%) had neuropathy and among VBD male patients, 54 (65%) had neuropathy. Conclusion: So, it can be concluded that if regular screening is done for serum vitamin B12 in symptomatic patients irrespective of age, a number of problems can be reduced or cured by diagnosing VBD patients and treating them with vitamin B12 either by dietary modification or medicinal supplementation.

Introduction: Bhutanese school children are vulnerable to vitamin B12 deficiency as outbreaks of micronutrient deficiency diseases have been a common occurrence. The study presents the status of vitamin B12 deficiency among boarding school children from those seven districts. Methods: A cross-sectional study was conducted to determine serum vitamin B12 level. Data and blood samples were collected from 448 boarding school children from the seven districts of Bhutan. Serum cobalamin levels were assessed and relationship between factors analyzed. Results: The study found that 64 % of the school children were found to have vitamin B12 deficiency. Adjusted Odds Ratio for the vitamin deficiency among boarding school children from lower secondary and higher secondary schools were 4.05 and 3.3 respectively, when compared to those from the primary school. Starches were the most commonly served foods in boarding schools, while the animal source foods were served twice or less in a month. Conclusion: The study found a high prevalence of Vitamin B12 deficiency among boarding school children from seven districts. Boarding school meals had very less frequency of animal source foods.

B12 Deficiency

ABSTRACT: CONTEXT AND OBJECTIVE: The prevalence of vitamin B12 deficiency varies from 5.8% to 30% among patients undergoing long-term treatment with metformin. Because of the paucity of data on Brazilian patients, this study aimed to determine the frequency of B12 deficiency and related factors among Brazilian patients with type 2 diabetes mellitus (T2DM) using metformin. DESIGN AND SETTING: Cross-sectional study at a public university hospital. METHODS: Patients with T2DM and a control group of non-diabetics were included. Serum B12 levels were measured and biochemical B12 deficiency was defined as serum levels < 180 pg/ml. Associations between B12 deficiency and age, duration of T2DM, duration of use and dosage of metformin, and use of proton pump inhibitors (PPIs) or histamine H2 antagonists were determined. RESULTS: 231 T2DM patients using metformin (T2DM-met) and 231 controls were included. No difference in the frequency of PPI or H2-antagonist use was seen between the groups. B12 deficiency was more frequent in the T2DM-met group (22.5% versus 7.4%) and this difference persisted after excluding PPI/H2-antagonist users (17.9% versus 5.6%). The factors that interfered with serum B12 levels were PPI/H2-antagonist use and duration of metformin use ≥ 10 years. Use of PPI/H2-antagonists was associated with B12 deficiency, with an odds ratio of 2.60 (95% confidence interval, 1.34-5.04). CONCLUSIONS: Among T2DM patients, treatment with metformin and concomitant use of PPI/H2-antagonists are associated with a higher chance of developing B12 deficiency than among non-diabetics.

Background: Vitamin B12 deficiency may be related to peripheral neuropathy in people with type 2 diabetes mellitus (T2DM). Level of B12 in T2DM observed by many investigators showed variable results. Studies on vitamin B12 in T2DM are very limited in Bangladesh. Objectives: To observe serum vitamin B12 level in newly diagnosed T2DM patients. Methods: Observational cross-sectional study encompassing 50 newly diagnosed T2DM and 50 controls as per American Diabetes Association (ADA) criteria. Vitamin B12 and Hemoglobin A1c (HbA1c) were measured for all. Results: Both mean (492.46±28.82 vs. 346.48±19.65 pg/mL, mean±SEM; p=<0.001) and median (435.50 vs. 334.50 pg/mL) values of serum vitamin B12 were found to be higher in T2DM than those of controls. None of the diabetic subjects were found to be B12 deficient whereas 6 were borderline deficient; these frequencies were 7 and 11 respectively among the controls. Vitamin B12 level was statistically similar in patients with or without clinically evident peripheral neuropathy (mean±SEM; 523.48±39.39 vs. 441.84±38.76 pg/mL, p=0.172). B12 level showed positive correlation with fasting plasma glucose (FPG, r=0.285, p=0.061) and HbA1c (r=0.287, p= 0.043) in diabetes group but there was no correlation with body mass index (BMI). Conclusion: Vitamin B12 is found sufficient in newly diagnosed Bangladeshi T2DM patients.

B12 Deficiency

Objectives: This study aimed to determine the prevalence of vitamin B12 deficiency amongst diabetic patients on metformin therapy. Methods: This cross-sectional study was conducted at general clinics at the University Health Center and diabetes outpatient clinics at Sultan Qaboos University Hospital, Muscat, Oman, between January and December 2017. All Omani adults who were diagnosed with type 2 diabetes mellitus and took metformin were invited to participate in the study. The variables included in this study were age, gender, duration of diabetes, dose and duration of metformin therapy, haemoglobin and glycosylated haemoglobin level. Results: A total of 248 subjects were included (response rate = 95.4%) of which 26 (10.5%) were vitamin B12 deficient and 53 (21.4%) were borderline deficient. The mean daily dose of metformin was highest among vitamin B12 deficient group (1,981 ± 222 mg; P = 0.004). Conclusion: The prevalence of vitamin B12 deficiency is considerable among diabetic patients on metformin therapy. Further research is needed to confirm the need for routine screening and monitoring.Keywords: Type 2 Diabetes Mellitus; Prevalence; Metformin; Vitamin B12 Deficiency; Oman.
