Background: Nutritional interventions during the first 1000 days of life improves lifelong health. Better pre-conceptional maternal nutrition improves the nutrition of the early embryo. Vitamins B12 and folate are important for fetal neural development. Vitamin B12 deficiency is common in India. Methods: In the Pune Rural Intervention in Young Adolescents (PRIYA) adolescents (N=557, 226 females) were provided with vitamin B12 (2μg/day) with or without multiple micronutrients, or a placebo, from preconception until delivery. All groups received mandatory iron and folic acid. We used the Bayleys Scale of Infant Development (BSID-III) at 24-42 months of age to investigate effects on offspring neurodevelopment. We examined cord blood concentrations of brain-derived neurotropic factor (BDNF). Results: Participants in the three groups had similar baseline B12 levels. These improved in the B12 supplemented groups at pre-conceptional and pregnancy (28 weeks gestation) measurements, reflected in higher cord holo-TC levels compared to the placebo. Neurodevelopmental outcomes are available for 74 children. Offspring in the B12 alone group (n=21) performed better than the placebo (n=27) on cognition (p=0.044) and language (p=0.020) domains (adjusted for maternal baseline B12 levels). There were no differences between the B12+MMN (n=26) and placebo group. Cord blood BDNF levels were highest in the B12 alone group (not statistically significant). Conclusion: Pre-conceptional vitamin B12 supplementation improved maternal B12 status and offspring neurodevelopment at 2 years of age. The usefulness of cord BDNF as a marker of brain development needs further investigation. Our results highlight the importance of intervening in the pre-conceptional period.

Background: The first thousand days window does not include the pre-conceptional period. Maternal pre-conceptional health has a profound influence on early embryonic development (implantation, gastrulation, placentation etc). Nutrition provided by B-complex vitamins is important for fetal growth, especially neural development. We report effects of a maternal pre-conceptional vitamin B12 and multi micronutrient (MMN) supplementation on offspring neurodevelopmental performance.Methods: In the Pune Rural Intervention in Young Adolescents trial (PRIYA), adolescents (N = 557, 226 females) were provided with vitamin B12 (2 μg/day) with or without multiple micronutrients, or a placebo, from preconception until delivery. All groups received mandatory iron and folic acid. We used the Bayley's Scale of Infant Development (BSID-III) at 24–42 months of age to investigate effects on offspring neurodevelopment.Results: Participants had similar baseline B12 levels. The levels improved in the B12 supplemented groups during pre-conception and pregnancy (28 weeks gestation), and were reflected in higher cord blood holotranscobalamin (holo-TC) levels compared to the placebo group. Neurodevelopmental outcomes in the B12 alone group (n = 21) were better than the placebo (n = 27) in cognition (p = 0.044) and language (p = 0.020) domains (adjusted for maternal baseline B12 levels). There was no difference in neurodevelopmental outcomes between the B12 + MMN (n = 26) and placebo group. Cord blood Brain Derived Neurotrophic Factor (BDNF) levels were highest in the B12 alone group, though not significant.Conclusion: Pre-conceptional vitamin B12 supplementation improved maternal B12 status and offspring neurodevelopment at 2 years of age. The usefulness of cord BDNF as a marker of brain development needs further investigation. Our results highlight the importance of intervening during pre-conception.

Introduction: An unusual case of a 19 year old female, presenting with fever, pallor and hepatosplenomegaly for one month. She had microcytic anemia on peripheral smear examination but her bone marrow aspiration & biopsy revealed a hypercelluar marrow with megaloblastic erythroid hyperplasia. Resolution of fever within 48 hours of Vitamin B12 supplementation, initiated in view of the megaloblastic bone marrow picture & low serumVitamin B12 level, suggests a causal association. Conclusion: Vitamin B12 deficiency seems to be an unusual cause of PUO (Pyrexia of unkown origin) which should be ruled out in every case of PUO.

Background: To estimate the prevalence of vitamin B12 deficiency in a rural south Indian community and to evaluate the association between metformin use and prevalent vitamin B12 deficiency in people with T2DM stratified by oral vitamin B12 supplementation.Methods: Using a cross sectional study design, a random sample of people with T2DM (N=438) was recruited from a rural community. Vitamin B12 deficiency was defined as serum B12 ≤200pg/ml. Data on metformin dose, duration of use, oral vitamin B12 supplementation, and diet were collected. Laboratory measurements included complete blood count, tests for hepatic, renal, and thyroid function, as well as serum vitamin B12 levels and HbA1c.Results: The prevalence of vitamin B12 deficiency in people with T2DM was 11.2% (95% Confidence Interval (CI) 8.2%-14.1%). The odds of vitamin B12 deficiency in patients receiving a metformin dose of 2 grams/day were 4 times higher compared to those receiving ≤1 gram/day, after adjusting for oral B12 supplementation (odds ratio 4.2;95% CI 1.5-11.8). The odds of vitamin B12 deficiency in those taking metformin and receiving oral vitamin B12 supplementation were lower compared to those on metformin and not receiving vitamin B12 supplementation (adjusted odds ratio 0.20; 95% CI 0.06-0.70).Conclusions: Vitamin B12 deficiency affects 1 in 10 people with T2DM, is associated with higher dose metformin use, and oral vitamin B12 supplementation mitigates B12 deficiency in this group.

A 3 month old infant exclusively breast fed presented with vomiting and poor weight gain with purpuric and echymotic patches all over the body. The child also had hyperpigmentation over knuckles and icterus. Laboratory investigations revealed severe dimorphic anemia with thrombocytopenia, elevated bilirubin and LDH levels and severe vitamin B12 deficiency. Following vitamin B12 supplementation there was improvement in well-being including feed tolerance, icterus resolved and in follow up lab studies there was improvement in hemoglobin and platelet counts along with reduced bilirubin levels. Through this case report we want to emphasize the possibility of vitamin B12 deficiency presenting as hemolytic anemia and psuedothrombotic microangiopathy.

Abstract Maternal nutrition is an important factor for infant neurodevelopment. However, prior magnetic resonance imaging (MRI) studies on maternal nutrients and infant brain have focused mostly on preterm infants or on few specific nutrients and few specific brain regions. We present a first study in term-born infants, comprehensively correlating 73 maternal nutrients with infant brain morphometry at the regional (61 regions) and voxel (over 300 000 voxel) levels. Both maternal nutrition intake diaries and infant MRI were collected at 1 month of life (0.9 ± 0.5 months) for 92 term-born infants (among them, 54 infants were purely breastfed and 19 were breastfed most of the time). Intake of nutrients was assessed via standardized food frequency questionnaire. No nutrient was significantly correlated with any of the volumes of the 61 autosegmented brain regions. However, increased volumes within subregions of the frontal cortex and corpus callosum at the voxel level were positively correlated with maternal intake of omega-3 fatty acids, retinol (vitamin A) and vitamin B12, both with and without correction for postmenstrual age and sex (P < 0.05, q < 0.05 after false discovery rate correction). Omega-3 fatty acids remained significantly correlated with infant brain volumes after subsetting to the 54 infants who were exclusively breastfed, but retinol and vitamin B12 did not. This provides an impetus for future larger studies to better characterize the effect size of dietary variation and correlation with neurodevelopmental outcomes, which can lead to improved nutritional guidance during pregnancy and lactation.

Background/Objective: Recent literature has identified links between vitamin B12 deficiency and depression.We compared the clinical response of SSRI-monotherapy with that of B12-augmentation in a sample of depressed patients with low normal B12 levels who responded inadequately to the first trial with the SSRIs. Methods: Patients with depression and low normal B12 levels were randomized to a control arm (antidepressant only) or treatment arm (antidepressants and injectable vitamin B12 supplementation). Results: A total of 199 depressed patients were screened. Out of 73 patients with low normal B12 levels 34 (47%) were randomized to the treatment group while 39 (53%) were randomized to the control arm. At three months follow up 100% of the treatment group showed at least a 20% reduction in HAM-D score, while only 69% in the control arm showed at least a 20% reduction in HAM-D score (p<0.001). The findings remained significant after adjusting for baseline HAM-D score (p=0.001). Conclusion: Vitamin B12 supplementation with antidepressants significantly improved depressive symptoms in our cohort.

ABSTRACT Diabetic neuropathy is the most common and debilitating microvascular complication leading to nontraumatic amputations. Identifying the role of vitamin B12 in the etiology of neuropathy is crucial because simple vitamin B12 replacement may reverse neurologic symptoms if confirmed. Large proportion of vegetarians and patients on metformin have been associated with lowering of vitamin B12 levels. We have undertaken study on 60 vegetarian subjects between the age of 30 and 60 years, 20 healthy controls, 20 type 2 diabetes mellitus patients who were on metformin with peripheral neuropathy (DMWN), and 20 diabetics without peripheral neuropathy (DMWON). Vitamin B12, homocysteine, and folate levels were measured, and holotranscobalamin (holoTC) is also included, to improve the diagnosis of tissue vitamin B12 status, as holoTC is the biologically active fraction and more sensitive index of vitamin B12 status than total vitamin B12 itself. Complete history and clinical evaluation for neuropathy and electroneuromyography were recorded. Results In the DMWN group, vitamin B12 levels were significantly higher than in the DMWON group and controls [1013 (564-1501) pmol/l, 387 (245-731) pmol/l, and 305 (234-472) pmol/l respectively]. Similarly, serum holoTC was also found to be significantly higher in the DMWN [203.8 (129-300) pmol/l] group compared with the DMWON [94.4 (42.2-230.6) pmol/l] group and controls [74 (40-170) pmol/l]. Whereas mean levels of homocysteine and folate did not show any significant difference between groups, significant increase in fasting blood sugar and HbA1c was seen in the DMWN group compared with DMWON group and controls. Duration of diabetes is also significantly more in DMWN group compared with DMWON group. Conclusion We found that vitamin B12 and holoTC levels were high in patients with DMWN and DMWON groups compared with controls. Our study demonstrated that peripheral neuropathy was not associated with vitamin B12 deficiency in diabetics. These findings merit further research on a larger population to investigate into the cause of diabetic neuropathy, the factors involved, and benefit of vitamin B12 supplementation in these patients. Key messages Vitamin B12 status has no association with diabetic peripheral neuropathy. How to cite this article Noorjahan M, Madhavi K, Priscilla C, Jabeen SA.
