A case-control method (488 septic patients and 527 healthy individuals) was carried out in this study to investigate the genetic relationship between CFH polymorphisms (rs3753394 C/T, rs1065489 G/T and rs1061170 C/T) and susceptibility to sepsis caused by bacterial infections in Chinese Han populations.
Homozygosity for the complement factor H Y402H polymorphism, which is thought to reduce complement inhibition, was associated with less frequent SIRS/sepsis (the adjusted odds ratio for the homozygous variant complement factor H Y402H [CC] carriers was 0.3, 95% confidence interval, 0.1-0.7, p = .005).
