A New Biomarker on Bone Resorption in Chronic Otitis Media: Osteoprotegerin and NLRP3 Inflammasome Gene Polymorphisms

xlomafota13 shared this article with you from Inoreader A New Biomarker on Bone Resorption in Chronic Otitis Media: Osteoprotegerin and NLRP3 Inflammasome Gene Polymorphisms Via Otolaryngology Indian Abstract Chronic Otitis Media (COM) is a chronic inflammation of the middle ear and mastoid with persistent membrane perforation and hearing loss. Osteoprotegerin (OPG) and NOD like receptor protein 3 (NLRP3) play an important role in bone metabolism. The aim of the study was to investigate the role of OPG and NLRP3 gene polymorphism on ossicular chain resorption in COM. Fourty COM patients and 20 healhty control group were included in the study. While 20 patients underwent ossiculoplasty, 20 patients underwent type 1 tympanoplasty. DNA was isolated from peripheral blood using the DNA kit. OPG gene c.226A > C (p.Thr76Pro) and NLRP3 gene c.592G > A (p. Val198Met) polymorphisms were genotyped using melting curve analysis technique. NLRP3 gene polymorphism were determined in 6 of 20 patients (30%) in ossiculoplasty group, 4 of 20 patients (20%) in type 1 tympanoplasty group and 3 of 20 patients (15%) in control group. OPG gene polymorphism were determined in 5 of 20 patients (25%) in ossiculoplasty group, 3 of 20 patients (15%) in type 1 tympanoplasty group and 1 of 20 patients (5%) in control group, respectively. There was no statistically significant difference between groups regarding to results. Although the difference was not significant NLRP3 and OPG gene polymorphisms were higher in the ossiculoplasty group. Since NLRP3 and OPG gene polymorphisms were determined to be higher numerically in the ossiculoplasty group, OPG and NLRP3 gene regulation system may have an effect on ossicular chain destruction in COM.
