Background: This study was aimed at the evaluation of the relationship between genetic polymorphisms of catechol- O-methyltransferase (COMT) (rs4680:A > G-Val158Met, rs6269:A > G, rs4633:C > T, rs4818:C > G) and pain sensitivity after lumbar discectomy. Methods: All patients had one-level symptomatic disc herniation from L3 to S1. The primary data recorded included visual analogue pain scales assessing back and leg pain, Oswestry Disability Questionnaire assessing quality of life and pain intensity, received/filled pre- and postoperatively. Each subject was genotyped for single-nucleotide polymorphism in the COMT gene. Clinical outcome was measured by difference between pre- and postoperative values and those results were analyzed with genetics findings. Results: Pain intensity was associated with the COMT polymorphism. Carriers of rs6269 AA, rs4633 TT, rs4818 CC, and rs4680 AA genotypes were characterized by the lowest preoperative scores related to pain intensity and lower pain intensity at 1 year after the surgery. The rs4633 CC, rs4680 GG genotypes demonstrated significant clinical improvement in VAS score at 1 year after the surgery. Patients with COMT haplotype associated with low metabolic activity of enzyme (A_C_C_G) showed better clinical outcome measured by ODI score and VAS score 1 year after surgery. We did not observe any significant correlation between leg pain and single-nucleotide polymorphisms in the COMT gene. Conclusions: The results of our study indicate that polymorphism in the COMT gene may play an important role in the mechanism of pain perception, which may have a potential implication for clinical decision-making in the future.
