Pernicious anemia treatment effectiveness
Rural health challenges in Western Uganda: pernicious anemia masquerading as recurrent lower limb weakness-a case report.
High relevance to autoimmune treatment
We explored the impact of vitamin B12 treatment on individuals suffering from pernicious anemia, an autoimmune disorder that affects the body’s ability to absorb this essential vitamin. In a recent case report, a 51-year-old man from Uganda presented with lower limb weakness, which had returned after an earlier bout of vitamin B12 deficiency.
Upon investigation, he was diagnosed with pernicious anemia, a condition that can cause a range of symptoms due to the body’s inability to produce intrinsic factor, crucial for vitamin B12 absorption. After starting parenteral methylcobalamin therapy, we observed significant improvements in his symptoms, highlighting how effective vitamin B12 can be in managing this disorder.
This case emphasizes the need for awareness and timely diagnosis of vitamin B12 deficiency among healthcare providers, especially in resource-limited settings. Such proactive management can lead to recovery and improved quality of life for those affected.

B12 treatment for autoimmune disorder
Neurological and Cardiovascular Complications Revealing Biermer's Disease: A Case Report.
High relevance for treatment effects
We explored the intriguing case of a 56-year-old man diagnosed with Biermer's disease, also known as pernicious anemia, an autoimmune condition that leads to a lack of intrinsic factor and, consequently, vitamin B12 malabsorption. This patient presented with unusual symptoms: not just digestive concerns like melena, but also notable neurological effects such as memory issues and gait disturbances.
During our examination, we discovered symptoms indicative of cerebellar ataxia, along with a red and swollen limb that pointed toward deep vein thrombosis (DVT). The tests revealed severe macrocytic anemia and confirmed a deficiency in vitamin B12 while keeping folate levels normal. Following a thorough diagnosis—including gastroscopy, ultrasound, and blood tests—we initiated a treatment plan that included vitamin B12 supplementation and anticoagulant therapy.
The outcome of our intervention was promising, with significant clinical improvement observed in the patient’s condition. Our findings reinforce the essential role of vitamin B12 in managing this type of autoimmune disorder, particularly when neurological and cardiovascular complications arise.

Vitamin B12 may treat arthritis
Vitamin B12 inhibits peptidylarginine deiminases and ameliorates rheumatoid arthritis in CAIA mice.
Highly relevant to autoimmune treatment
We investigated the potential of vitamin B12 as a treatment for rheumatoid arthritis, particularly focusing on its ability to target an enzyme called peptidylarginine deiminase isoform 4 (PADI-4). PADI-4 plays a crucial role in a process called citrullination, which is often disrupted in autoimmune conditions like rheumatoid arthritis.
Our findings revealed that vitamin B12 effectively inhibits PADI-4, showing a preference for this enzyme over another similar one, PADI-2. This inhibition corresponds to a decrease in overall cellular citrullination, including the citrullination of histone H3, which is also mediated by PADI-4.
Additionally, we observed that hydroxocobalamin, a special form of vitamin B12, significantly reduced the severity of collagen type II antibody-induced arthritis in mice. It also lowered the expression of key inflammatory factors and cytokines associated with rheumatoid arthritis, such as IL-17A, TNFα, and IL-6.
These promising results suggest that vitamin B12 might be an effective therapeutic avenue for managing rheumatoid arthritis, warranting further investigation in future studies.

Pain relief
I have rheumatoid arthritis and, in 2010, my pain worsened significantly. I discovered that a gluten-free diet alleviated most of my pain, but I still faced severe discomfort in my feet and hands. After researching B12 deficiency, I started taking Jarrow methyl B12 and I now experience minimal pain. I'm regaining my life.

Vitamin B12 supplementation benefits autoimmune patients
A new perspective on vitamin B12 deficiency in rheumatology: a case-based review.
Study highlights autoimmune deficiencies
We explored the impact of vitamin B12 on patients with autoimmune disorders, particularly those experiencing symptoms often attributed to their underlying conditions. The study presented three cases of individuals with neuropathic pain, depression, fatigue, and muscle weakness, who had their symptoms initially misattributed to rheumatic diseases.
Upon starting vitamin B12 supplementation, these patients showed nearly complete resolution of their symptoms, highlighting the potential benefits of this vitamin in treating related health issues. Interestingly, several participants did not display obvious deficiencies in vitamin B12 levels according to lab tests, suggesting that even those who appear to have sufficient levels could still benefit from supplementation.
Furthermore, we delved into research indicating the nerve-protective properties of vitamin B12, which could play a crucial role in managing pain and neuropathy associated with long-standing rheumatic diseases. Therefore, we recommend that healthcare providers consider checking vitamin B12 levels early in the diagnostic journey for autoimmune conditions, and think about offering supplementation regardless of laboratory findings.

Study on vitamin B12 in GBS
Coexistence of Guillain-Barré Syndrome and Subacute Combined Degeneration of the Spinal Cord Due to Autoimmune Gastritis: A Case Report and Literature Review.
Moderate relevance to autoimmune research
We explored a unique case involving a 54-year-old man who experienced symptoms that indicated both Guillain-Barré syndrome (GBS) and complications from autoimmune gastritis (AIG). Notably, he displayed progressive numbness and weakness along with gastrointestinal symptoms, which are often linked to vitamin B12 deficiency.
As part of his treatment, we utilized intravenous immunoglobulin alongside methylcobalamin, a form of vitamin B12. What was particularly interesting is that while the immunoglobulin treatment is typically aimed at addressing GBS, vitamin B12 was also administered to combat the neurological effects stemming from the deficiency due to AIG.
Our findings revealed that following these treatments, the patient showed significant clinical improvement before discharge. However, it's crucial to note that while vitamin B12 is commonly understood to aid neurological functions, the specific impact of its isolated use in this case remains unclear without additional studies focusing solely on its effectiveness in autoimmune disorders like GBS.
Overall, the integration of vitamin B12 treatment, particularly in the context of GBS and AIG, opens up discussions about managing similar cases in the future, although further research is necessary to firmly establish its benefits.

Vitamin B12 and autoimmune gastritis
Risk Factors Analysis and Predictive Model Construction for Autoimmune Gastritis: A Nationwide Multicenter Case-Control Study in China.
Moderate relevance to dietary impacts
We investigated the dietary and lifestyle factors associated with autoimmune gastritis (AIG) among Chinese patients. Our study involved 479 individuals across seven centers in China, where we collected detailed clinical and lifestyle data.
From the findings, we noticed that most AIG patients were middle-aged females. Interestingly, our analysis highlighted that a diet rich in vitamin B12 appeared to play a protective role against AIG. This means that the more vitamin B12 included in the diet, the better the potential outcomes regarding autoimmune gastritis.
Furthermore, we established a predictive model that relied on various factors. Alongside vitamin B12, using larger amounts of cooking oil and having comorbid autoimmune thyroid disease emerged as key risk factors for developing AIG. The predictive model demonstrated promise, with ROC curve scores indicating a reasonable ability to differentiate AIG patients from others.
Overall, our exploration suggests that dietary habits, including vitamin B12 intake, can be pivotal in managing the risk and prognosis of autoimmune gastritis. However, we recognize that additional research is essential to fully understand the effects of vitamin B12 in this context.
