Abstract

Gastrointestinal (GI) manifestations are common in autistic children. Polyunsaturated fatty acids (PUFAs) and carnitine are anti-inflammatory molecules and their deficiency may result in GI inflammation. The relationship between the increased frequency of GI manifestations and reduced levels of PUFAs and carnitine was not previously investigated in autistic patients. This study was the first to investigate plasma levels of PUFAs and serum carnitine in relation to GI manifestations in autistic children. Plasma levels of PUFAs (including linoleic, alphalinolenic, arachidonic "AA" and docosahexaenoic "DHA" acids) and serum carnitine were measured in 100 autistic children and 100 healthy-matched children. Reduced levels of serum carnitine and plasma DHA, AA, linolenic and linoleic acids were found in 66%, 62%, 60%, 43% and 38%, respectively of autistic children. On the other hand, 54% of autistic patients had elevated ω6/ω3 ratio. Autistic patients with GI manifestations (48%) had significantly decreased levels of serum carnitine and plasma DHA than patients without such manifestations. In addition, autistic patients with GI manifestations had significantly increased percentage of reduced serum carnitine (91.7%) and plasma DHA leve...Continue Reading

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here

Autism

Autism spectrum disorder is associated with challenges with social skills, repetitive behaviors, and often accompanied by sensory sensitivities and medical issues. Here is the latest research on autism.
