IL6 and preterm premature rupture of the membranes: Eleven out of 77 proteins were elevated in infants with FIRS (n = 11) vs. no FIRS (n = 16); 10/77 proteins in infants exposed to HCA (n = 14) vs. no HCA (n = 13); 7/77 in infants with elevated CRP/IL-6 (n = 5) vs. infants without elevated markers (n = 28) and no significantly elevated proteins were found in cord blood from infants born after spontaneous onset of delivery (PTL/PPROM, n = 26) compared with physician-initiated delivery (n = 7).
