ESR1 and juvenile polyposis syndrome: Khury et al. [56] and Stambough et al. [57] indicated that no association could be determined between the delta change in serum WBC, CRP and ESR before and after two-stage revision for PJI and reinfection risk, although a return to normal serology infrequently occurs before reimplantation, and Ackmann et al. [58] considered plasma D-dimer does not help to guide the timing of reimplantation in two-stage exchange for PJI; these serum markers provide no additional diagnostic accuracy to determine the timing of reimplantation.
