Folic acid improves rheumatoid arthritis treatment
Folic acid-modified ginger-derived extracellular vesicles for targeted treatment of rheumatoid arthritis by remodeling immune microenvironment via the PI3K-AKT pathway.
High relevance for treatment options
We explored the use of ginger-derived extracellular vesicles modified with folic acid to treat rheumatoid arthritis, a painful autoimmune condition. By enhancing these vesicles to target the inflammatory cells in affected joints, we found that they help shift the immune response towards healing. Our in vitro and in vivo studies showed promising results: these folic acid-infused vesicles not only concentrated in the inflamed areas but also significantly reduced RA symptoms. This suggests that folic acid-modified vesicles could be a safe and effective alternative treatment option for RA.

Methotrexate withdrawal and folic acid
Risk Factors Associated with Adverse Events Leading to Methotrexate Withdrawal in Elderly Rheumatoid Arthritis Patients: A Retrospective Cohort Study.
High relevance for clinical practice
We examined a long-term study focusing on elderly patients with rheumatoid arthritis (RA) using methotrexate (MTX).

While higher MTX doses increased the risk of needing to stop treatment due to adverse effects, adding folic acid seemed to lower that risk significantly.

In fact, around 51.7% of patients had to discontinue MTX within 15 years, but those on folic acid had a much better outcome.

This suggests that doctors should consider lower MTX doses combined with folic acid for better results in elderly RA management.

PANS/PANDAS and folate treatment
Folate Receptor Alpha Autoantibodies in the Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS) and Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS) Population.
Significant association with treatment
We aimed to understand how folate receptor alpha autoantibodies (FRAAs) relate to symptoms in children diagnosed with Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS) and Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS). We analyzed serum samples from 47 children, aged 6 to 18, who carried these diagnoses.

Our results showed that a significant number of these children—about 63.8%—had binding or blocking FRAAs. Additionally, certain symptoms, like severe tics, linked with higher FRAA binding titers. Notably, we observed that kids with autism spectrum disorder (ASD) had lower binding titers of FRAAs.

A remarkable case highlighted how treatment with leucovorin, a form of folate, resulted in symptom improvements in a child with PANS/PANDAS who tested positive for FRAAs. These findings suggest that abnormalities in folate metabolism could play a role in the symptomatology of PANS/PANDAS, presenting the potential for folate-based therapies to be a viable treatment option.

Overall, this study sheds light on the connection between folate-related factors and pediatric neuropsychiatric disorders, calling for further research into leucovorin as a targeted treatment.

Hormonal balance restored
My wife, who has an autoimmune disorder related to hormonal imbalance, was prescribed folic acid and vitamin E. After trying a "pharmacy course", we sought a better quality supplement from iHerb, which proved beneficial, resulting in her improved health.

Affordable efficiency
If you have an autoimmune disorder and an MTFR gene mutation, this has been one of the few effective methylfolate supplements I've tried. It's economical and small in size, fulfilling the necessary levels for conception and healthy development.

Folate's Role in Rheumatoid Arthritis
Folic acid-modified ginger-derived extracellular vesicles for targeted treatment of rheumatoid arthritis by remodeling immune microenvironment via the PI3K-AKT pathway.
Folate-modified vesicles show promise
We explored the potential of folate-modified ginger-derived extracellular vesicles (FA-GDEVs) in treating rheumatoid arthritis (RA). This innovative approach aims to tackle the ongoing inflammation and joint damage that characterizes this autoimmune disorder. By using folate, which selectively targets specific receptors on inflammatory cells, we specifically directed these vesicles to M1 macrophages in inflamed joints.

Our findings show that FA-GDEVs can help encourage a shift from harmful M1 macrophages to a healing M2 phenotype. This shift is significant because M2 macrophages play a role in tissue repair and reducing inflammation. We also investigated how these vesicles activate the PI3K-AKT pathway, a crucial cellular pathway involved in regulating immune response.

In our in vivo studies, we noted that these folate-modified vesicles successfully concentrated in affected joints and led to a marked reduction in RA symptoms. Overall, it’s clear that FA-GDEVs present a promising therapeutic option for those suffering from rheumatoid arthritis, bringing together safety, affordability, and effectiveness in one approach.

Prodrug shows promise for arthritis
Prodrug Nanomedicine for Synovium Targeted Therapy of Inflammatory Arthritis: Insights from Animal Model and Human Synovial Joint Fluid.
High relevance for treatment innovations
We explored a promising new approach to treating inflammatory arthritis, focusing on a modified form of methotrexate (MTX) that uses folic acid to target inflamed joints. The study found that this prodrug could release the medication in a controlled way while reducing side effects common with traditional treatments.

In tests involving mouse models and human joint fluid samples, we observed that the prodrug not only accumulated in areas of inflammation but also matched the effectiveness of standard weekly MTX with much less dosage. While this treatment is still in the early stages, it shows exciting potential for improving care in those suffering from arthritis.

Ginsenoside delivery method effective
Oral liposomes encapsulating ginsenoside compound K for rheumatoid arthritis therapy.
Promising RA treatment strategy
We explored the effectiveness of a folic acid-targeted liposomal drug delivery system, known as FA-LP-GCK, for treating rheumatoid arthritis (RA). Ginsenoside compound K, while promising due to its immune-boosting and anti-inflammatory properties, faces challenges like poor solubility and absorption.

Our study found that FA-LP-GCK showed significant improvements, such as reduced joint swelling and lower levels of inflammatory markers in rat models of RA. This suggests FA-LP-GCK could be a promising new treatment option for patients struggling with this debilitating condition.

Improved mental clarity
This has helped me feel much better mentally and detox at a faster rate than normal. Caffeine no longer bothers me, and I can sleep and wake up early. I will definitely order again when it runs out. Thank you.
