Correlation of ADRB1 rs1801253 Polymorphism with Analgesic Effect of Fentanyl After Cancer Surgeries

Abstract

BackgroundOur study aimed to explore the association between β1-adrenoceptor (ADRB1) rs1801253 polymorphism and analgesic effect of fentanyl after cancer surgeries in Chinese Han populations.Material/MethodsPostoperative fentanyl consumption of 120 patients for analgesia was recorded. Genotype distributions were detected by allele specific amplification-polymerase chain reaction (ASA-PCR) method. Postoperative pain was measured by visual analogue scale (VAS) method. Differences in postoperative VAS score and postoperative fentanyl consumption for analgesia in different genotype groups were compared by analysis of variance (ANOVA). Preoperative cold pressor-induced pain test was also performed to test the analgesic effect of fentanyl.ResultsFrequencies of Gly/Gly, Gly/Arg, Arg/Arg genotypes were 45.0%, 38.3%, and 16.7%, respectively, and passed the Hardy-Weinberg Equilibrium (HWE) test. The mean arterial pressure (MAP) and the heart rate (HR) had no significant differences at different times. After surgery, the VAS score and fentanyl consumption in Arg/Arg group were significantly higher than in other groups at the postoperative 2nd hour, but the differences were not obvious at the 4th hour, 24th hour, and the 48th hour. The results suggest that the Arg/Arg homozygote increased susceptibility to postoperative pain. The preoperative cold pressor-induced pain test suggested that individuals with Arg/Arg genotype showed worse analgesic effect of fentanyl compared to other genotypes.ConclusionsIn Chinese Han populations, ADRB1 rs1801253 polymorphism might be associated with the analgesic effect of fentanyl after cancer surgery.

Genetic characterization of physical activity behaviours in university students enrolled in kinesiology degree programs

“…Indeed, recent published research supports a role for the ADRB1 Arg389Gly polymorphism in both the perception of pain (Wei et al 2015) and the psychological trait of persistence as assessed by the temperament and character inventory (Numajiri et al 2012). In addition, β3-adrenergic receptor agonists such as SR58611A (amibegron) have proven to be an effective treatment strategy for anxiety and depressive disorders (Stemmelin et al 2008).…”

Association between the rs7583431 single nucleotide polymorphism close to the activating transcription factor 2 gene and the analgesic effect of fentanyl in the cold pain test

“…Three minutes after administration, they underwent the cold pressor‐induced pain test again with the same dominant hand to determine PPL‐post. The analgesic effect of fentanyl in the preoperative cold pressor‐induced pain test was evaluated as the difference between PPL‐pre and PPL‐post …”

Labour analgesia; Molecular pathway and the role of nanocarriers: a systematic review

“…rs1801252 and rs1801253 are embedded single nucleotide polymorphisms (SNPs) in ADRB1 gene with clinical significance in hypertension, stroke, heart disease, pain and analgesic sensitivity. In Chinese population, different response according to variety of rs1801252 and rs1801253 SNPs to pain is reported, also Japanese population response to Fentanyl is affected by these SNPs [69][70][71].…”
