We explored the case of a 23-month-old boy suffering from severe pancytopenia linked to Imerslund-Gräsbeck syndrome, a rare condition caused by an inability to absorb vitamin B12. Upon diagnosis, the boy received vitamin B12 replacement therapy, which effectively addressed his symptoms and improved his health.
This case highlights the significance of early detection and treatment of IGS to avoid potential neurological damage. It's crucial to recognize this condition, even when neurological symptoms are absent, to provide timely care.

We focused on how oral vitamin B12 could help those with pernicious anemia, where absorption is usually impaired. Participants diagnosed with vitamin B12 deficiency due to this condition took a daily dose of 1000 μg of oral cyanocobalamin.
Over a year, an impressive 88.5% of them no longer showed deficiency after just one month, with significant improvements in vitamin B12 levels and related biological markers. Importantly, these benefits lasted throughout the study period.

We explored a rare condition called Transcobalamin deficiency, which hinders vitamin B12 transport in the body. This case involved a 2-year-old boy suffering from severe anemia and frequent infections.
After genetic tests revealed a specific mutation, we administered high doses of methylcobalamin. Remarkably, the child's health significantly improved, highlighting the importance of diagnosing and treating this deficiency early to avoid serious complications.

Effective for anemia
12 people found this helpful
I found this form of B12 to be effective. After dealing with blood cancer-related pernicious anaemia and declining haemoglobin levels, I researched B12 and discovered the activated version. Within a week of using this, my haemoglobin levels stabilised and eventually improved. While it's not the sole treatment needed for red blood cells, it is vital. Many doctors seem unaware of the importance of activated B12 for red blood cell formation.

Vital for red cells
8 people found this helpful
This vitamin is essential for all types of anaemia and red blood cell production. It's rare in plants, so it must be obtained externally. There are blood tests to ensure sufficient levels. I suffer from G6PD anaemia, and taking this with iron after consuming legumes helps mitigate the stress on my body.

We investigated how vitamin B12 treatment plays a role in addressing anemia in a young adolescent with complex health issues, including severe anemia, joint problems, and neurological symptoms. This individual presented with a deficiency in vitamin B12, alongside other autoimmune conditions, leading to a diagnosis of subacute combined degeneration of the spinal cord.
The patient's treatment regimen included high-dose intravenous methylprednisolone, immunoglobulin therapy, oral naproxen, and vitamin B12 supplementation, among others. We observed that the introduction of vitamin B12 into her treatment plan contributed to combating her anemia effectively. The combination of therapies, especially with vitamin B12, significantly improved her overall health and restored her quality of life.
Our findings highlight the importance of early diagnosis and prompt treatment in patients with complex autoimmune issues. Specifically, vitamin B12 emerges as a critical component in managing anemia related to such conditions. While the study is anecdotal, it reinforces the idea that vitamin B12 can be beneficial in improving anemia outcomes in similarly affected patients.

We explored a case of a 3-year-old girl diagnosed with Imerslund-Gräsbeck syndrome, a condition that causes vitamin B12 malabsorption and leads to anemia. After identifying novel mutations in the AMN gene, we initiated long-term oral vitamin B12 therapy.
Following treatment, her blood tests showed consistent improvement, indicating that oral B12 replacement can be an effective management strategy, especially for patients who can’t tolerate injections. This case underscores the importance of genetic testing for accurate diagnoses.

This case explores the journey of a 40-year-old woman who suffered from various nonspecific symptoms, mistakenly attributed to other health issues, for ten years. Her vitamin B12 levels were critically low, ultimately diagnosed as pernicious anemia.
After starting parenteral B12 treatment, we observed significant neurological improvements, underscoring how vital it is to recognize vitamin B12 deficiency as a potential cause of anemia, even when classic symptoms aren't present. This case reminds us to maintain a broad perspective for accurate diagnosis.

We explored a case involving a 51-year-old Ugandan man who experienced recurring lower limb weakness and was ultimately diagnosed with pernicious anemia. His condition stemmed from vitamin B12 deficiency, confirmed by blood tests showing macrocytic anemia and low cobalamin levels.
With treatment using methylcobalamin injections, he showed significant improvement. This case emphasizes the need for heightened awareness of vitamin B12 deficiency in diagnosing anemia, especially in areas with limited health resources.

We evaluated whether adding multiple micronutrients to iron-folic acid supplementation would better combat anemia in children aged 6-59 months in rural India. In a well-structured trial of 1,300 participants, we found no significant difference in hemoglobin levels or anemia cure rates between those receiving iron-folic acid alone and those receiving the additional micronutrients.
Both groups showed a similar rate of recovery, suggesting that iron-folic acid alone may be sufficient. This emphasizes the importance of adherence to existing supplementation protocols to tackle anemia effectively.

We conducted a study to explore how effective different vitamin B12 supplements are at increasing levels of this crucial vitamin in people with a deficiency. This clinical trial involved healthy adults who were found to have low B12 levels.
Our research spanned across three centers in Pakistan, where participants received either a new formulation of Sucrosomial vitamin B12 or conventional B12 supplements. They took a daily dose for seven days, and we measured their serum B12 levels at various points before and after the treatment.
What we found was quite significant: the Sucrosomial vitamin B12 was notably better at elevating and maintaining higher B12 levels in the bloodstream compared to traditional options. This is important because low vitamin B12 can lead to serious health issues, like megaloblastic anemia and neurological problems.
Overall, this innovative supplement could offer a valuable solution for individuals with B12 deficiency, especially those who may have absorption issues. Our findings support the potential of Sucrosomial vitamin B12 in enhancing health through improved nutrient bioavailability.

We sought to understand how effective vitamin B12 is in treating anemia in children. Our focus was on comparing two different methods of supplementation: parenteral (injections) and oral (pills). While previous studies in adults suggested both methods might have similar benefits, we found limited data for children, prompting our thorough investigation.
Our literature search pulled from multiple reputable databases for randomized controlled trials that specifically looked at vitamin B12 treatments in children with deficiency anemia. Of the thousands of studies reviewed, only one qualified for our analysis. In this study, children received an initial injection of vitamin B12 before being assigned to either the parenteral or oral treatment group.
We observed notable differences in the outcomes after three months. The children who received the parenteral treatment showed significantly higher vitamin B12 levels and better improvements in hemoglobin, indicating that this method may be more effective. However, we should note that the quality of the study was deemed high risk for bias, and there was no safety data reported, making it challenging to draw strong conclusions.
Overall, while the findings hint at a greater effectiveness of parenteral supplementation, the lack of robust evidence calls for caution in interpreting these results. Further high-quality research is necessary before definitive recommendations can be made.
