RESUMEN
Genetic variations in the solute carrier family 11 member 1 (SLC11A1) gene have been implicated in developing inflammatory disorders. However, it is still unclear whether such polymorphisms contribute to the pathogenesis of post-traumatic osteomyelitis (PTOM). Therefore, this study investigated the roles of genetic variations of the SLC11A1 gene (rs17235409 and rs3731865) in PTOM development in a Chinese Han cohort. The SNaPshot method was used for genotyping 704 participants (336 patients and 368 controls) for rs17235409 and rs3731865. Outcomes revealed that rs17235409 increased the risk of PTOM occurrence by dominant (p = .037, odds ratio [OR] = 1.44) and heterozygous models (p = .035, OR = 1.45), implying AG genotype as a risk factor for PTOM development. In addition, patients with AG genotype had relatively higher levels of inflammatory biomarkers than those with AA and GG genotypes, especially for the white blood cell count and C-reactive protein. Despite no statistically significant differences achieved, rs3731865 may reduce the PTOM susceptibility, suggested by the results of dominant (p = .051, OR = 0.67) and heterozygous (p = .068, OR = 0.69) models. In short, rs17235409 confers an elevated chance of developing PTOM, with AG genotype as a risk factor. Whether rs3731865 involves in the pathogenesis of PTOM requires further investigations.
