Background: Nutritional anaemia are common health problems. Most studies are done regarding iron deficiency anaemias. There are limited data regarding vitamin B12 deficiency anaemia especially in adolescents. Aims and objectives of the study were to find the prevalence of vitamin B12 deficiency among anaemic adolescents and to study various socio-demographic factors and hematological parameters associated with vitamin B12 deficiency. Methods: Cross sectional hospital based observational study of 211 adolescents (10 -18 year) with anaemia. Socio demographic characteristics like age, sex, education of mother & patient, socio- economic class, dietary history were noted for each patient. CBC including RBC indices and serum estimation of vitamin B12 level were done for each patient. Results: Anaemia was seen in 46.6% of adolescents. Vitamin B12 deficiency was seen in 49.76%. Vitamin B12 deficiency was significantly associated with male gender (p=0.032) and vegetarians (p=0.047). Moderate to severe degree of anaemia (p=0.016), macrocytosis (p= 0.000) and thrombocytopenia (p=0.007) was more observed in vitamin B12 deficient patients as compared to vitamin B12 non deficient groups. Statistically significant fall in mean haemoglobin level and increase in mean MCV values were seen with decreasing serum vitamin B12 level. Conclusions: Among anemic male and vegetarian adolescents vitamin B12 deficiency is a significant health problem. Hematological findings in peripheral blood are more associated with severe degree of vitamin B12 deficiency. Vitamin B12 supplementation along with IFA should be addressed through national programmes.

Abstract Urinary aminoimidazolecarboxamide (AIC), serum folate, and serum vitamin B12 values were determined in 84 apparently healthy individuals. An automated system for determination of AIC in urine is described. Despite claims to the contrary, we found no evidence of a strong relationship between elevated (e.g., >1.3 µg/mg of creatinine) AIC excretion as reflected in a casual sample of urine and folate or vitamin B12 deficiency. Urinary AIC values ranged from 0.10 to 5.20 µg/mg of creatinine. The mean for the population examined was 1.36 ± 1.02 µg/mg of creatinine.

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.

Background: Vitamin B12 deficiency is common in children but under diagnosed disorder. Helicobacter pylori infection plays an important role in the development of atrophic gastritis and related malabsorption. There may be a relationship between H.Pylori infection and vitamin B12 deficiency. Aims and Objective: To find out prevalence of Helicobacter pylori infection by endoscopic and histopathological findings, in children aged 2-18 years, with vitamin B12 deficiency. Materials and Methods: Seventy-eight patients with deficient serum vitamin B12 levels were evaluated. Upper GI Endoscopy was performed in all cases and gastric biopsies were obtained for histopathological examination and evidence of H. pylori infection. Results: Tissue biopsy revealed chronic atrophic gastritis in 09 patients and chronic antral gastritis in 52 patients. H. pylori infection by histology was positive in 45(57.70%) patients. We found significant correlation between atrophic gastritis and H. pylori infection, as well as between H. pylori infection and B12 deficiency. Conclusion: H.pylori has an effect on gastric mucosa, which affects the absorption of vitamin B12. Thus individuals with B12 deficiency should be subjected for diagnostic evaluation of H.pylori infection so that appropriate therapy can be initiated.

B12 Deficiency

Introduction: Clinical manifestations of vitamin B12 deficiency are mostly non-specific. An entity called subclinical deficiency has become popular where the need has arisen to perform costly investigations which indicate functional deficiency of vitamin B12 even when vitamin B12 levels are normal. These factors pose a challenge in planning management of patients. Aims and objectives : The study was conducted as an attempt to identify affordable and credible laboratory indicators of vitamin B12 deficiency which can be used as screening tests before choosing patients for further evaluation or treatment. Material and Methods : This was a time bound cross-sectional study where 100 adult patients who had undergone the following investigations were randomly chosen: Complete Blood Count with red cell indices, serum bilirubin and serum vitamin B12 levels. The sensitivity, specificity and predictive values (positive-PPV and negative-NPV) of the variables that could hypothetically identify vitamin B12 deficiency, both individually or in combinations were calculated and compared. Results and conclusion : Hemoglobin, MCV (Mean Corpuscular Volume), MCH (Mean Corpuscular Hemoglobin), platelets and bilirubin were not equally distributed between vitamin B12 deficient and normal groups(p values for these variables were 0.029, 0.000, 0.000, 0.003 and 0.029 respectively).When these variables were tested individually and in combination, the combination of [MCV=95 fl or MCH=30 pg or Platelets =1.4 lakh/µl or Bilirubin =1 mg/dl] had sensitivity of 68.2%, specificity of 85.7%, PPV of 78.9% and NPV of 77.4%. This proposed combination used as a screening test has potential for wide application considering its simplicity and cost advantage.

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.

Abstract Objective Vitamin B12 is not synthesized in the body and its only dietary sources are non-vegetarian. The breast milk of mothers in resource poor countries who are on predominantly vegetarian diets is deficient in vitamin B12. Hence exclusive breast feeding (EBF) may result in B12 deficiency in the infant, which can affect the neurodevelopmental outcome. Our aim was to study the serum vitamin B12 levels among EBF infants and identify the risk factors for B12 deficiency. Method This cross-sectional study was done among EBF, term, otherwise healthy infants, 1–6 month of age in the well-baby clinic .The sociodemographic data of mother and the infants’ anthropometric measurements were noted and blood samples were sent for complete blood count and serum vitamin B12 levels. The data were analysed using SPSS software version 16. Results We enrolled 149 EBF infants, aged 1–6 months and the mean age was 3.1 (±1.03) months. The mean serum vitamin B12 level was 199.91 (±112.523) pg/ml. Low serum vitamin B12 levels (<200 pg/ml) was seen in 95 (63.7%) infants. On multivariate analysis, there were no other significant risk factors for B12 deficiency in the infants. Conclusion The prevalence of vitamin B12 deficiency among EBF infants is 63.7%. Because of its importance in neurological development during infancy, there is an urgent need to address this issue while promoting exclusive breast feeding.
