1.	Kalliomäki, Maija-Liisa, et al. (författare) Genetic susceptibility to postherniotomy pain. The influence of polymorphisms in the Mu opioid receptor, TNF-alpha, GRIK3, GCH1, BDNF and CACNA2D2 genes 2016 Ingår i: Scandinavian Journal of Pain. - : Walter de Gruyter GmbH. - 1877-8860 .- 1877-8879. ; 12, s. 1-6 Tidskriftsartikel (refereegranskat)abstract Background and aims: Despite improvements in surgical technique, 5%-8% of patients undergoing herniorrhaphy still suffer from clinically relevant persistent postherniotomy pain. This is a problem at both individual and society levels. The aim of this study was to determine whether or not a single nucleotide polymorphism in a specific gene contributes to the development of persistent pain after surgery. Methods: One hundred individuals with persistent postherniotomy pain, along with 100 without pain matched for age, gender and type of surgery were identified in a previous cohort study on patients operated for groin hernia. All patients underwent a thorough sensory examination and blood samples were collected. DNA was extracted and analysed for single nucleotide polymorphism in the Mu opioid receptor, TNF-alpha, GRIK3, GCH1, BDNF and CACNA2D2 genes. Results: Patients with neuropathic pain were found to have a homozygous single nucleotide polymorph in the TNF-alpha gene significantly more often than pain-free patients (P = 0.036, one-tailed test). Conclusions: SNP in the TNF-alpha gene has a significant impact on the risk for developing PPSP. Implications: The result suggests the involvement of genetic variance in the development of pain and this requires further investigation.
