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

ABSTRACT: BACKGROUND Our study aimed to explore the association between ?1-adrenoceptor (ADRB1) rs1801253 polymorphism and analgesic effect of fentanyl after cancer surgeries in Chinese Han populations. MATERIAL AND METHODS Postoperative 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. RESULTS Frequencies 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. CONCLUSIONS In Chinese Han populations, ADRB1 rs1801253 polymorphism might be associated with the analgesic effect of fentanyl after cancer surgery.

Project description:Purpose:Various analgesic modalities are adopted for perioperative analgesia in breast cancer surgeries. This study aimed to compare the efficacy of intravenous morphine versus serratus anterior plane block (SAPB) and erector spinae plane block (ESPB) in breast cancer surgeries. Patients and Methods:Seventy-five breast cancer patients undergoing modified radical mastectomy from January 2020 to June 2020 were randomly allocated into 3 groups; the morphine group received morphine 0.1 mg/kg, the SAPB group received ultrasound-guided SAPB with 25 mL bupivacaine 0.25% and the ESPB group received ultrasound-guided ESPB with 25 mL bupivacaine 0.25%. A visual analogue scale (VAS) 0-10 was used to evaluate pain postoperatively, where 0 denotes no pain and 10 worst pain. If any patient in the 3 studied groups reported breakthrough pain with VAS ? 4 then a bolus of 3 mg morphine was given. Results:There was no difference in VAS scores between the 3 groups postoperatively. Morphine consumption was higher in the morphine group (9.19 ± 2.32 mg) than the SAPB group (4.00 ± 1.55 mg) and the ESPB group (4.20 ± 1.64 mg), respectively. First time to receive postoperative morphine was significantly longer for the ESPB and SAPB groups than the morphine group (20.40 ± 4.98 hours), (19.00 ± 5.9 hours), (5.00 ± 4.62 hours), respectively. Intraoperative hemodynamics and fentanyl consumption showed no difference between groups, whereas postoperative mean arterial blood pressure values at 2 and 4 hours were higher in the morphine group. Ramsay sedation score and postoperative nausea and vomiting values in the post anesthesia care unit were higher for the morphine group compared to the SAPB and ESPB groups. No complications related to the blocks were reported. Conclusion:SAPB and ESPB can be used as an effective and safe alternative to opioids with fewer side effects in breast cancer patients undergoing modified radical mastectomy. Trial Registration:This trial was prospectively registered at Clinical Trials.gov on 22 January 2020 with registration number NCT04248608 (https://register.clinicaltrials.gov/prs/app/action/SelectProtocol?sid=S0009JS5&selectaction=Edit&uid=U0004LIG&ts=7&cx=-81xkwa).

Project description:BACKGROUND: The P2X7 receptor is a member of the P2X family of adenosine 5'-triphosphate-gated cation channels. Several recent studies have demonstrated that this receptor is involved in mechanisms related to pain and inflammation. However, unknown is whether polymorphisms of the P2RX7 gene that encodes the human P2X7 receptor influence pain sensitivity and analgesic effects of opioids. The P2RX7 gene is known to be highly polymorphic. Thus, the present study examined associations between fentanyl sensitivity and polymorphisms in the P2RX7 gene in 355 Japanese patients who underwent painful orofacial cosmetic surgery. RESULTS: We first conducted linkage disequilibrium (LD) analyses for 55 reported single-nucleotide polymorphisms (SNPs) in the region within and around the P2RX7 gene using genomic samples from 100 patients. In our samples, 42 SNPs were polymorphic, and a total of five LD blocks with six Tag SNPs (rs2708092, rs1180012, rs1718125, rs208293, rs1718136, and rs7132846) were observed. Thus, we further analyzed associations between genotypes/haplotypes of these Tag SNPs and clinical data using a total of 355 samples. In the genotype-based association study, only the rs1718125 G>A SNP tended to be associated with higher pain scores on a visual analog scale 24 h after surgery (VAS24). The haplotype-based association study showed that subjects with homozygous haplotype No.3 (GTAAAC; estimated frequency: 15.0%) exhibited significantly higher cold pain sensitivity and lower analgesic effects of fentanyl for acute cold pain in the cold pressor test. Conversely, subjects who carried haplotype No.1 (ACGGAC; estimated frequency: 24.5%) tended to exhibit lower cold pain sensitivity and higher analgesic effects of fentanyl. Furthermore, subjects with homozygous haplotype No.2 (GCGGAC; estimated frequency: 22.9%) exhibited significantly lower VAS24 scores. CONCLUSIONS: Cold pain sensitivity and analgesic effects of fentanyl were related to the SNP and haplotypes of the P2RX7 gene. The patients with the rs1718125 G>A SNP tended to show higher VAS24 scores. Moreover, the combination of polymorphisms from the 5'-flanking region to exon 5 recessively affected cold pain sensitivity and analgesic effects of opioids for acute cold pain. The present findings shed light on the involvement of P2RX7 gene polymorphisms in naive cold pain sensitivity and analgesic effects of fentanyl.
