CD14, the major receptor for bacterial lipopolysaccharide (LPS) as well as other microbial antigens, is a component of the innate immune system. We hypothesized that a single nucleotide C>T polymorphism at position -159 in the CD14 gene that results in elevated CD14 production would influence susceptibility to preterm premature rupture of membranes (PPROM) and spontaneous preterm birth (SPTB) in multi-fetal pregnancies. DNA from 107 mother-twin and three mother-triplet pairs was analyzed. Pregnancy outcomes were obtained after completion of testing. CD14*T homozygosity was present in 39.3% of 28 women whose pregnancies ended with PPROM, as opposed to 18.1% of 72 pregnancies without a SPTB (P=0.03). There was no relation between the fetal CD14 genotype and PPROM. The likelihood ratio (LR) for PPROM was 2.2 for women homozygous for CD14*T. The LR increased to 3.3 and 3.6 if the CD14 polymorphism was present in combination with previously determined maternal polymorphisms in the genes coding for the inducible 70kDa heat shock protein (hsp70-2) and the interleukin-1 receptor antagonist (IL1RN), respectively. Thus, an enhanced maternal pro-inflammatory immune response to LPS may increase susceptibility to PPROM in multi-fetal pregnancies.
