Linoleic acid in multiple sclerosis: failure to show any therapeutic benefit
Abstract:
We have studied the effect of a dietary supplement with linoleic acid (LA) in 76 patients with MS. We could detect no effect of this supplement on the progression of neurological findings, the relapse rate, or the severity of relapses. We were also able to show that oral supplementation with a linoleic acid preparation would raise the blood level of LA in these patients. We were unable to show that there was any reduction in the linoleic acid blood levels associated with acute relapses of MS during this study.
Insights
Linoleic acid (LA) supplementation did not affect multiple sclerosis (MS) progression or relapse rates in patients. While oral LA increased blood LA levels, it did not reduce levels during acute MS relapses.
Area of Science:
- Neurology
- Nutritional Science
- Immunology
Background:
- Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system.
- Dietary fatty acids, including linoleic acid (LA), are being investigated for their potential role in managing MS.
- Evidence regarding the efficacy of LA supplementation in MS is limited.
Purpose of the Study:
- To investigate the effect of oral linoleic acid (LA) supplementation on the clinical progression and relapse characteristics of patients with multiple sclerosis (MS).
- To determine if LA supplementation influences blood LA levels in MS patients, particularly during acute relapses.
Main Methods:
- A study involving 76 patients diagnosed with multiple sclerosis (MS).
- Participants received oral supplementation with a linoleic acid (LA) preparation.
- Assessment of neurological findings, relapse rate, and relapse severity.
- Monitoring of blood linoleic acid (LA) levels before and during the study period, including acute relapses.
Main Results:
- Linoleic acid (LA) supplementation showed no significant effect on the progression of neurological deficits in MS patients.
- No discernible impact was observed on the relapse rate or the severity of relapses among supplemented patients.
- Oral LA supplementation successfully increased blood levels of linoleic acid (LA) in the study participants.
- The study could not demonstrate a reduction in linoleic acid (LA) blood levels associated with acute MS relapses.
Conclusions:
- Dietary linoleic acid (LA) supplementation does not appear to modify the clinical course of multiple sclerosis (MS) in terms of disease progression or relapse activity.
- While oral LA supplementation can elevate blood LA concentrations, this intervention did not show a therapeutic benefit in reducing MS relapse-associated LA levels.
- Further research may be needed to explore other fatty acids or therapeutic strategies for managing multiple sclerosis (MS).
