  • Association between rs1799971 Polymorphism in OPRM1 Gene on Opioid Requirements after Surgery in Asians: A Meta-analysis

    ObjectiveTo evaluate the relationship between OPRM1 gene rs1799971 polymorphism and opioid analgesics requirement after surgery in Asians. MethodsWe electronically searched databases including CNKI, CBM, VIP, WanFang Data, EMbase and MEDLINE to collect studies about the correlation between OPRM1 gene rs1799971 polymorphism and opioid analgesics requirement after surgery in Asia. The retrieval time was from the establishment to March 1st, 2015. Two reviewers independently screened literature, extracted data and assessed the risk bias of including studies, and then meta-analysis was performed by using RevMan 5.2 software. ResultsA total of 10 case-control studies involving 1 612 patients were included. The results of meta-analysis showed that the requirement of opioid analgesics after surgery for GG genotype carriers was more than AG carriers (SMD=-0.44, 95%CI -0.61 to -0.28, P<0.000 01), AA genotype carriers (SMD=-0.55, 95%CI -0.71 to -0.38, P<0.000 01), and AA+AG genotype carriers (SMD=-0.50, 95%CI -0.66 to -0.35, P<0.000 01). ConclusionThe current evidence showed that the requirement of opioid analgesics after surgery for GG genotype of rs1799971 polymorphism in OPRM1 gene is higher in Asians. Due to the limited quality and quantity of included studies, the above results are needed to be further validated by more studies.
