Active clinical trials for "Vitamin B 12 Deficiency"

Folic acid and vitamin B12 play an interdependent role in key cellular processes, namely deoxyribonucleic acid synthesis, cell division, red blood cell formation, and nervous system myelination. A deficiency of either vitamin will predispose teenagers to many diseases, which persist across their lifespan. Fortification of food with micronutrients has been promoted to reduce micronutrient deficiencies. A large segment of vulnerable populations in low- and middle-income countries (LMICs) resides in rural settings and has limited access to large-scale commercialized fortified foods. In such operational constraints, the use of locally (small-scale) fortified cereals could be an alternative intervention. The study aims to evaluate the effectiveness of small scale folic acid and vitamin B12 fortified cereals in improving folate and vitamin B12 status, growth velocity, puberty status, anaemia, cognitive development and mental health among teenage girls, in rural rift valley of Ethiopia.

CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.

Women of reproductive age are a high-risk population for anemia and micronutrient deficiencies, and there is increasing evidence of the role of periconceptional nutritional status in the risk of birth defects and other pregnancy complications. However, there is limited population-based data from India, where the burden and consequences of these deficiencies is unacceptably high. The objective of this study is to conduct a population-based biomarker survey to determine the burden of anemia and vitamin B12 and folate status in women of reproductive age, as part of a periconceptional surveillance program in Southern India. Findings from this biomarker survey will establish the burden of anemia and B-vitamin deficiencies in women of reproductive age, and inform the development of a randomized efficacy trial of quadruple-fortified salt for the prevention of anemia and birth defects in Southern India.

To obtain up-to-date data on nutritional status of older adults, a national dietary survey will be conducted in 2022/2023, providing data on the consumption of foods and enabling the assessment intakes of energy and specific nutrients. Participating subjects will be also screened for micronutrient status using blood biomarkers (focusing into vitamin D, folic acid, vitamin B12, and iron).

Increased plasma homocysteine level is associated with macroangiopathy and nephropathy in type 2 diabetes. Also increased levels of serum homocysteine are associated with microalbuminuria which is associated with increased cardiovascular morbidity and mortality among the patients with type 2 diabetes. With B12 supplementation homocysteine level can be reduced .Type 2 diabetes as a metabolic syndrome may show improvement in glycaemic control with Vitamin B12 therapy as there is correction of hyperhomocysteinemia. In studies it is proved that combination of vit B12, folic acid and vit B6 are effective for hyperhomocysteinemia.There are no such separate trials on the use of vit B12 alone. This therapy may be used in large number of type 2 uncontrolled diabetic hyperhomocysteinemic patients. this study was planned with following objectives to study effect of Vitamin B12 supplementation on glycaemic control in poorly controlled hyperhomocysteinemic type 2 diabetic patients Glycaemic control measured by levels of glycosylated haemoglobin (HbA1c) at baseline and 4 weeks Fasting blood sugar level at baseline and 4 weeks Serum homocysteine/ vitamin B12 levels at baseline and 4 weeks Serum lipid profile at baseline and 4 weeks

The goal of this observational study is to compare the nutritional intake among pregnant women with a strict plant-based diet versus an omnivorous diet. The main aim is to compare vitamin B12 intake. Participants will be asked to: fill out a health questionnaire fill out a three-day food diary undergo blood sampling Researchers will compare pregnant women with a strict plant-based diet and pregnant women with an omnivorous diet to see if their nutritional intake is comparable.

The aim of this pilot study is to conduct a study on geriatric population in Slovenia (non-users of dietary supplements/medicines with vitamine D, vitamin B12 and protein) and assess deficiency of selected nutrients, and to investigate the efficiency of the innovative food supplement prototype in improving nutritional status of elderly adults.

The purpose of this study is to compare the efficacy and safety profile of a new oral vitamin B12 formulation (Eligen® B12) with intramuscular B12 in restoring normal B12 (cobalamin) concentrations in subjects with low cobalamin levels (<350 pg/mL).

Objective: To determine the effectiveness of oral versus intramuscular Cobalamin (vitamin B12) by restore cobalamin parameter in blood at 8, 26 and 52 weeks in ≥ 65 aged patients with Cobalamin Deficiency. Design: Noninferiority randomised controlled trial, pragmatic and multi-center in the primary healthcare setting (Madrid Region). Participants: ≥ 65 aged patients with Cobalamin Deficiency. Patients give inform consent. Number of patients: 320 (160 each arm). Assignment: randomized simple (automatic system). Variables. Main outcome variable: Cobalamin level standardization (yes/no). Secondary outcome variables: Adverse events. Adherence measurement of treatment. Health related quality of life questionnaire (Euroqol-5D). Satisfaction and preferences. Other variables: Gender. Age. Live alone. Vegetarian diet. Alcohols consume. Clinic Variables (symptoms and physical examination) and blood parameters. Drugs consume. Causes of all losses and withdrawals. Number of patients (age and gender) who declined to participate. All data (excluding patient identification data) will be record in an electronic database. Intervention group: oral Optovite® B12 1000 gammas. Control group: idem intramuscular. Analysis: Descriptive analysis (screening phase). Baseline comparison of the two intervention groups. Effect of cobalamin (main outcome variable). Security. Quality of life. Adherence measurement of treatment.

During fetal life and infancy, an adequate cobalamin status is important for normal growth and central nervous system development. During the last years we have detected cobalamin deficiency in a number of infants admitted to the Pediatric Department with various symptoms, including neurological symptoms and feeding problems. Cobalamin treatment is given to the infants with biochemical cobalamin deficiency, and leads to loss of symptoms and in improved physical condition. In this study we want to establish the prevalence of cobalamin deficiency in infants with gastrointestinal symptoms and/or feeding problems. Cobalamin status will be investigated in all children aged 8 months and younger, admitted to the Pediatric Department with these symptoms. In a randomised intervention trial we will evaluate the effect of cobalamin supplementation in children with these symptoms and metabolic evidence of impaired cobalamin status. Study hypothesis: Cobalamin treatment given to the infants with biochemical cobalamin deficiency, will lead to loss of symptoms and in improved physical condition.
