There was no association between ERα PvuII and XbaI polymorphisms and SLE susceptibility; however, the combination of the TC/AA and CC/GG genotypes of ESR α PvuII and XbaI polymorphisms were more frequent in SLE patients.
The percentage of Aiolos + CD8+ T cells was weakly correlated with ESR in SLE patients and RF in RA patients (r s = 0.37, p = 0.038; r s = 0.34, p = 0.044, respectively).
