Vitamin B12 deficiency in infancy may cause failure to thrive, severe neurological disorders and megaloblastic pancytopenia. It is well known that infants born with deficient vitamin B12 storage have increased the risk of vitamin B12 deficiency. Vitamin B12 deficiency is more prevalent in infancy in Sanliurfa province (at the southeast region of Turkey). The aim of this study was to determine the frequencies of vitamin B12, folic acid and iron deficiencies in pregnants and their babies at birth and to what extend the mothers' deficiency becomes effective on babies' deficiencies. The study groups were constituted by 180 pregnant women and their single and term babies. Venous blood samples of pregnants were obtained 1-3 h before delivery and babies' cord bloods were collected at birth. Vitamin B12 and folic acid levels were measured with electro chemiluminiscence method; serum iron and iron binding capacities were measured by colorimetric method and complete blood counts were performed by automatic blood counter. Mean vitamin B12 levels in maternal and cord blood serum were 130 +/- 61.7 pg/ml and 207 +/- 141 pg/ml; mean folic acid levels were 8.91 +/- 6.46 ng/ml and 17.8 +/- 11.8 ng/ml; mean serum iron levels were 56.9 +/- 37.5 microg/dl and 147 +/- 43.2 microg/dl; and mean transferrin saturations were 11.8 +/- 8% and 65.6 +/- 24%, respectively. There were vitamin B12 deficiency (<160 pg/ml) in 72% of the mothers and 41% of the babies, and severe deficiency (<120 pg/ml) in 48% of the mothers and 23% of the babies. Folic acid deficiency was found in 12% of the mothers, but was not found in the babies. There were iron deficiency in 62% of the mothers and 1% of the babies. There were statistically significant correlation between maternal and cord blood serum vitamin B12 levels (r = 0.395, P < 0.001) and folic acid levels (r = 0.227, P = 0.017), while there were no correlation between maternal and cord blood iron levels and transferrin saturations. The study results showed that vitamin B12 deficiency is prevalent in pregnants in this region and that 41% of infants have born with deficient vitamin B12 storages. Therefore, prophylactic use of vitamin B12 by pregnant women in Sanliurfa and other poor communities could have considerable benefits to prevent vitamin B12 deficiency and its complications in infants.

The deoxyuridine suppression test (dUST) was used to evaluate human immunodeficiency virus type 1 positive (HIV-1) patients with low serum levels of vitamin B12 and/or low red cell folate and to assess any possible interferences of azydothymidine (AZT) in this test. The dUST was studied in 29 HIV-1 positive patients, 18 without low serum vitamin B12 or low red cell folate and 11 with low serum vitamin B12 (6 patients), low red cell folate (4 patients) and 1 case with both. The role of AZT was studied using different concentrations (0.2, 2.5 and 10 microM/ml) in 2 groups: 1 group of 5 patients with vitamin B12 and/or folate deficiency and another group consisting of 13 healthy subjects. Methotrexate (MTX)(50 micrograms/ml) was added to induce a folate megaloblastic pattern in the latter group. Results of the dUST in the HIV-1 group without low levels of serum vitamin B12 fell within the health-related reference interval values. A vitamin B12 deficiency was only detected in 1 case in the HIV-1 group with low serum vitamin B12, although a folate deficiency pattern was observed in the 4 patients with low red cell folate. In the healthy subjects AZT induced a dose-dependent decrease of the MTX-induced folate megaloblastic pattern. The pattern was also observed in the group of patients with vitamin B12 or folate deficiency, although AZT did not entirely interfere with the dUST. The effect of AZT on the dUST was attributed to a decrease in the incorporation of the isotope in the absence of deoxyuridine. The dUST is useful in differentiating vitamin B12 deficient patients from HIV-1 infected patients with low levels of serum vitamin B12.

Introduction: Severe acute malnutrition (SAM) is a severe form of malnutrition affecting nearly 20 million children worldwide. Besides increasing the risk of death and disease, malnutrition also leads to growth retardation and impaired psychosocial and cognitive development. Vitamin B12 and folate are water-soluble essential micronutrients critical in average growth and development, particularly during infancy and childhood. A deficiency of folate and vitamin B12 can result in anemia, poor growth, and increased infections, and vitamin B12 deficiency can cause irreversible neurologic damage to the developing brain. We conducted this study to assess serum folate and vitamin B12 levels in children with SAM at admission and determine its relation with their developmental milestones. Materials and Methods: One hundred admitted SAM children between ages 6 and 59 months were taken to assess serum folate and vitamin B12 levels status in a tertiary care hospital and determine its relation with their developmental milestones. Results: The majority of the participants were in the age group 6–12 months (64%), rural (95%), the lower class of socioeconomic status (76%), and incomplete immunization (63%). Serum vitamin B12 and folate levels were found to be significantly associated with different domains of childhood development. Conclusion: This analysis revealed a high prevalence of vitamin B12 deficiency among malnourished children aged 6–59 months. We found that serum vitamin B12 level and folic acid were significantly associated with developmental delay in all domains (gross motor, fine motor, language, and social) of milestones.

Anemia, hematinic deficiencies, and hyperhomocysteinemia in younger and older oral lichen planus patients

BackgroundLow folate and vitamin B12 levels have negative effect on pregnancy outcomes but there is paucity of data on their levels among Indian women. Ferritin and haemoglobin are associated with maternal mortality and low birth-weight. Our aim was to estimate the prevalence of deficiency of serum folate and vitamin B12, and low levels of serum ferritin and blood haemoglobin among women of childbearing age from a rural population of South India.MethodsWe conducted a community-based cross-sectional study among 15-35 year women in a rural district. We used multistage stratified random sampling. Trained staff interviewed women to collect socio-demographic information and draw blood samples. We analysed samples for serum folate, vitamin B12, ferritin and blood haemoglobin levels and computed means and medians. We computed the proportion of deficiency based on cut-offs recommended by WHO. We examined the association of levels with age, parity and current pregnancy or breastfeeding by multi-variable regression using Stata 13.0.ResultsWe recruited 979 women. One-fifth (185, 19%) were pregnant and one-fifth (196, 20%)were breastfeeding. Median serum folate levels were 2.5 ng/ml (IQR, 1.2-4.8), median vitamin B12 levels were 228.0 pg/ml (IQR, 121 - 390), median ferritin levels were 13.0 μg/l (IQR, 6.0 - 20.0) and median blood haemoglobin levels were 12.1 mg/dl (IQR, 10.7 – 13.6). Low levels of serum folate, vitamin B12, ferritin and haemoglobin were found in 57% (95% CI, 54-60%), 44% (95% CI, 41-48%), 46% (95% CI, 43-49%) and 28% (95% CI, 25-31%) respectively. Women with folic acid deficiency had two times higher prevalence of having vitamin B12 deficiency. In adjusted regression analysis folate levels were lower in older and breastfeeding women, but not associated with parity and were higher among pregnant women. Similar associations were not found with Vitamin B12 deficiency. Ferritin levels were higher in older women; but not associated with parity, pregnancy or breastfeeding. Haemoglobin levels were lower in pregnant and breastfeeding women.ConclusionOur findings suggest that folic acid, vitamin B12 and iron deficiency are important public health problems in India. We observed that half of the women of childbearing age were deficient in these nutrients. Folic acid and vitamin B12 deficiencies co-exist and should be supplemented together.

IntroductionChronic infection with Helicobacter pylori (Hp) is an essential cause of gastrointestinal pathologies in adults. Despite being a microorganism proven to play a role in vitamin B12 deficiency by causing gastric atrophy, Hp’s role in patients with non-atrophic gastritis has not been fully explained. Our study investigated whether the presence and density of Hp is related to vitamin B12 and folate deficiencies in patients with non-atrophic gastritis.MethodsThis retrospective cohort study analyzed the following parameters, vitamin B12, folate, and mean red blood cell volume (MCV) in the hemogram; these were measured simultaneously in patients diagnosed with non-atrophic gastritis who had undergone gastroscopy to investigate Hp levels. Patients with conditions that could have caused vitamin B12 and folate deficiencies were excluded from the study. The study included 244 patients who met the criteria. The Sydney classification was used for histopathologic grading and staging of gastric biopsies of patients with gastritis.ResultsThere was no relationship between the presence and density of Hp with vitamin B12 levels. However, folate levels were significantly lower in Hp-positive patients than in Hp-negative patients (p = 0.017). Folate levels were substantially lower in patients with chronic pan-mucosal gastritis than in patients with chronic inactive gastritis (p = 0.034). Statistically, a significant difference was found between folate levels on the basis of neutrophil activity and inflammation score (p = 0.011 and p <0.001, respectively).ConclusionsAlthough there was no statistically significant relationship between the presence and density of Hp and vitamin B12, our study found an association between folate levels and Hp density. This may be associated with the time for the depletion of vitamin B12 and folate stores and the relatively early stage of gastritis. In cases with vitamin B12 and folate deficiencies, appropriate studies should be performed for specific epidemiological reasons in respective fields.

Background: Severe acute malnutrition is the important health issue children affected in India. It is often associated with Iron, Vitamin B12 and Folic acid and other micronutrient deficiencies. These reports of declining trend of Iron and folic acid deficiency with implementation of national anemia control programme. Estimation of Serum Folate and Vitamin B12 levels in SAM children aged 6-60 months with anemia was the objective of the study.Methods: A hospital based observational study on 80 children admitted to nutritional rehabilitation center were suffering from severe acute malnutrition (SAM) in the age group of 6-60 months enrolled in the study during the period November 2018 to May 2019 .Data was collected using a predesigned and pretested Proforma, containing details of feeding, socio-economic and development history. Blood samples were sent for measurement of plasma vitamin B12 and serum folate levels. Statistical analysis was done using SPSS version 20.0.Results: Out of 80 children, majority were between the age group of 24-60 months and majority were boys (53.8%). Mean Vitamin B12 and folic acid levels being 384.61 and 8.95 respectively. 45% and 3.8% had vitamin B12 and folic acid deficiencies respectively. Majority of neurological changes and developmental delays were noted in B12 deficient group. Of the 36, B12 deficient children, majority had moderate anaemia (40.2%), normal total count (41.7%), 60% had neutropenia, 44.4% had lymphocytosis, majority had normocytic (30.9%) anemia.Conclusions: There was a moderate to high prevalence of vitamin B12 deficiency among malnourished children. Folate deficiency was found only in few. Efforts should be directed to prevent its deficiency in pregnant and breastfeeding women and their infants with special attention on malnourished children.B12 and folate deficiency shall be considered in all cases with SAM irrespective of blood indices. Treatment will have impact on prognosis of child.

Context:This study summarizes the prevalence of vitamin B12 and folic acid deficiency in the population coming to tertiary care center in Western Maharashtra along with the main presenting symptom routinely misinterpreted in daily practice.Aims and Objectives:1. To study the prevalence of vitamin B12 and folic acid deficiency in the population of western Maharashtra. 2. To correlate the symptoms with serum vitamin B12 and folic acid levels.Materials and Methods:The present study is a cross-sectional observation study carried out on patients from western Maharashtra seeking medical attention on outpatient and inpatient basis in the medicine department of a teaching institute in Karad. One-hundred patients were selected on basis of below mentioned symptoms viz. tingling and numbness in extremities, dizziness, unsteady gait, early tiredness, forgetfulness, proximal weakness, distal weakness, chronic headache, less interest in work, chronic loose stools, strict vegetarians, alcoholics, intake of medications like anti-tubercular treatment, surgery involving terminal ileum. Serum vitamin B12 and folic acid levels of these patients were observed. Deficiency of vitamin B12 and folic acid was studied in 4 groups: (a) Absolute vitamin B12 deficiency; (b) Absolute folic acid deficiency; (c) Borderline vitamin B12 deficiency; (d) Combined vitamin B12 and folic acid deficiency.Results:Of the 100 cases, 33% patients were vegetarian. Folic acid deficiency formed the major chunk of deficiency group. Six percent patients had neuropsychiatric manifestations. Depressive illness in 1% patients, dementia in 0% patients, forgetfulness in 1% patients, mania/hallucination in 0% patients each, and chronic headache in 1% patients. Neuropathy in form of loss of reflexes, decreased touch sensation was present in 9% patients. Posterior column involvement viz. Loss of joint position, vibration, positive Romberg's sign were present in 34% patients of vitamin B12 and folic acid deficiency.Conclusion:In a small study, it was found that megaloblastic anemia may have symptoms and signs referable to several systems including hematology, dermatology, gastrointestinal, neurology, and neuropsychiatry.
