Background Previous studies had indicated that interleukin-1 beta (IL-1 β ) gene single nucleotide polymorphisms (SNPs) associate with different inflammatory diseases. However, potential links between these polymorphisms and susceptibility to extremity chronic osteomyelitis (COM) remain unclear. This study aimed to investigate relationships between IL-1 β gene polymorphisms (rs16944, rs1143627, rs1143634, and rs2853550) and risks of developing extremity COM in Chinese Han population.Methods Altogether 233 extremity COM patients and 200 healthy controls were genotyped for the four tag SNPs of the IL-1 β gene using the SNapShot genotyping method. Comparisons were performed regarding genotype distribution, mutant allele frequency, and four genetic models (dominant, recessive, homozygous, and heterozygous models) of the four SNPs between the two groups.Results Significant associations were identified between rs16944 polymorphism and the risk of developing COM by dominant model ( P = 0.026, OR = 1.698, 95% CI 1.065-2.707) and heterozygous model ( P = 0.030, OR = 1.733, 95% CI 1.055-2.847). Although no statistical differences were found of rs1143627 polymorphism between the two groups, there existed a trend that rs1143627 may be linked to an elevated risk of developing COM by outcomes of dominant ( P = 0.061), homozygous ( P = 0.080) and heterozygous ( P = 0.095) models. However, no statistical correlations were found between rs1143634 and rs2853550 polymorphisms and susceptibility to COM in Chinese Han population.Conclusions To our knowledge, we reported for the first time that IL-1 β gene rs16944 polymorphism may contribute to the increased susceptibility to extremity COM in Chinese Han population, with genotype of AG as a risk factor.
