Abstract
OBJECTIVES:
To evaluate plasma amino acid (AA) concentrations in patients affected by fibromyalgia (FM) and to study the relationships between their levels and FM clinical parameters.DESIGN AND METHODS:
20 AAs were assessed in 34 FM patients and in 18 healthy volunteers by means of a modified version of the Waters picotag method.RESULTS:
Significant lower plasma taurine, alanine, tyrosine (Tyr), valine, methionine, phenylalanine and threonine concentrations, and the sum of essential AAs were observed in FM patients vs healthy controls (P<0 .05="" aas="" and="" b="" brain="" caa="" competing="" fm="" for="" in="" of="" ratio="" reduced="" significantly="" sum="" the="" tryptophan="" tyr="" uptake="" were="" with="">A significant correlation was found between FM clinical parameters and certain AAs.CONCLUSIONS:
Our results suggest probable defects of gut malabsorption of certain AAs in FM patients. Moreover, given the reduced Tyr CAA' ratio in FM patients, a possible impairment of the cathecolaminergic system in the FM syndrome may be suggested.- PMID:
