Krebs metabolites in Autism


These are the metabolites produced by every cell in the body except possibly the red cells of the blood

 

An interesting factor is that there are few publications but the biochemical laboratories in various countries are willing to measure them for the parents of autistic children and in some way give interpretation.

 

Currently it must be made clear that not only are the changes that are seen generally within the normal range but that the ‘slightly high’ or ‘slightly low’ findings as shown by laboratory work are commonly of no value.  Few give creatinine ratios  for the levels of compounds that they found and so it becomes exceptionally difficult to interpret findings.

Excretion of Krebs metabolites in urine

 

Shaw W, Kassen E, Chaves E. Increased urinary excretion of analogs of Krebs cycle metabolites and arabinose in two brothers with autistic features. Clin Chem. 1995 Aug;41(8 Pt 1):1094-104. (done in two brothers).  Clearly this work needs to be repeated in larger numbers of cases, and as long term studies associated with diet.
