OBJECTIVE To describe the magnitude and distribution of folate and vitamin B12 deficiency in Mexican children. MATERIALS AND METHODS Folate and vitamin B12 serum concentrations were measured in a probabilistic sample of 2 099 children. Adjusted prevalence, mean concentrations and relevant associations were calculated based on series of logistic and linear regression models. RESULTS The over...

A comparative study was done to determine the profile of vitamin B12 and folate status in Malaysians during two different periods. For the period of 1987/88, we analysed a total of 9,162 cases (inpatients) referred for vitamin B12 estimation and 10,290 cases for folate estimation. We found that 2.6% were vitamin B12 deficient and 31.2% were folate deficient. For the period of 1992/93, of the 9,...

The association between metformin use and low vitamin B12 levels in type 2 diabetes mellitus patients is well-established. However, many aspects of the topic remain to be elucidated. There is still controversy on the current diagnostic approaches to vitamin B12 deficiency. It is now believed that measuring the serum levels of the vitamin may not reflect its metabolic status. Moreover, there wer...

OBJECTIVES Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disease characterised by paroxysmal attacks of serosal inflammation. Colchicine is highly effective in preventing these attacks but it may also disrupt the intestinal absorption of vitamin B12. We hypothesised that patients treated with colchicine for a prolonged period could develop deficiency of the vitam...

OBJECTIVE To examine the prevalence of low serum folate and vitamin B12, in association with elevated serum homocysteine, in a representative sample of older Australians. METHODS During 1997-2000, 3,508 persons aged 50+ years were examined in a population-based cohort study conducted in two postcodes, west of Sydney, Australia. Of these, 2,901 participants (82.7%) provided fasting blood for e...

INTRODUCTION The neurological manifestation of vitamin B12 deficiency can occur as a result of peripheral nerve pathology or lateral and posterior column involvement, also known as "sub-acute combined degeneration". This case report demonstrates an unusual presentation of SCD with normal B12 level. CASE PRESENTATION A 39-year-old man was referred to the outpatient neurology clinic with a two ...

BACKGROUND Treatment with folic acid and vitamin B12 appears to be effective in lowering total plasma homocysteine (tHcy) concentrations, but whether vitamin B12 alone lowers tHcy in patients with normal vitamin B12 status is unknown. The aims of the present study were to explore the effect of individual supplementation with folic acid or vitamin B12 on tHcy concentrations in hemodialysis (HD) ...

abstract objective: diabetic peripheral neuropathy (dpn) is one of the most common complications of diabetes. beside the known factors such as hyperglycemia in the pathogenesis of this complication, other etiologies may play role in the pathogenesis of this complication. the aim of this study was the evaluation of the role of serum vitamin d and vitamin b12 levels in this process. material and ...

conclusions demyelinating disease, anterior ischemic optic neuropathy, non-arteritic anterior ischemic optic neuropathy, autoimmune disease, and hereditary optic neuropathy could cause optic neuropathy. normal cbc parameters and the absence of clinical manifestations of vitamin b12 deficiency could not rule out its diagnosis. careful physical examinations and history-taking with a classical app...

background : increased level of serum homocysteine is one of the risk factor of atherosclerosis. its production related in some sulfur amino acids such as methionine. some important cofactors that are involved in metabolic pathways of this amino acid are folate and vitamin b12. we have assessed the status of methionine, folic acid, and vitamin b12 in some coronary atherosclerotic male patients....
