Indoxyl sulfate and pcresyl sulfate in accordance with age. The dots indicate the geometric implies of indoxyl sulfate (IndS) and pcresyl sulfate (PCS) in decades of age (,30 years, 309 years, 409 years, 509 years, 609 years and 70 years). The numbers above the horizontal axis would be the number of subjects within the a variety of age classes. The curves are calculated from a regression model with log IndS and log PCS as dependent variables and age and agesquared as independent variables. For IndS the Pvalues in the linear and squared terms have been 0.035 and 0.0024 respectively. The corresponding Pvalues for PCS have been 0.070 and 0.004. doi:10.1371/journal.pone.0079682.gRegression analysis identified renal function, age and sex as independent determinants of serum levels of both cometabolites. The dependence with the serum concentrations of indoxyl sulfate and pcresyl sulfate on renal function is expected as each cometabolites are wellknown uremic retention molecules [31]. Moreover, recent proof indicates that uremia per se may profoundly alter the composition from the gut microbiome [32]. In line together with the latter, we observed improved generation of pcresyl sulfate along the progression of chronic kidney illness [33]. The association amongst the serum concentrations of indoxyl sulfate and pcresyl sulfate and age is exceptional and intriguingand confirms preceding observations in chronic kidney illness individuals [23]. These observations assistance the hypothesis that aging goes in conjunction with a trend towards the Bacteroides enterotype and as a result much more prominent proteolytic fermentation and primarily concur with data from previous “classical” microbiology studies [34,35]. Whether these alterations are related to a reduced immune function or whether or not they are resulting from concomitant modifications in nutrition, gastrointestinal tract physiology, comorbidity and use of medication with advancing age remains to become established.Table 1.
