Multivariable analysis confirmed that carriage of the variant IL-10 ATA haplotype [Multivariable Odds Ratio (MOR) 1.9, P = 0.05)] and MBL2 codon 54Asp (MOR 2.0, P = 0.04) were independently associated with histologic chorioamnionitis, while homozygosity for the variant TGFB1-800G/-509T (GT) haplotype (MOR 0.2, P = 0.04), and carriage of TNFRSF6-1377A/-670G (AG) haplotype (MOR 0.4, P = 0.03) remained negatively associated with histologic chorioamnionitis. This evidence concerns the gene FAS and chorioamnionitis.
