Five single nucleotide polymorphisms (SNPs) of the ADYC9 gene in 163 patients in preterm labor were genotyped: rs879619, rs2601796, rs2531988, rs2531995, and rs2230739. Additionally, rs598961 of the PDE4B gene and rs1042719 of the ADRB2 gene were included for analysis. Patients with CC genotype of ADCY9 rs879619 had a 2.0-fold (95% confidence interval [CI]: 1.3, 3.2) higher hazard of time to delivery than T allele carriers. Patients with combined genotypes of CC in ADCY9 rs879619, AA in PDE4B rs598961, and GC, CC in ADRB2 rs1042719 showed a greater hazard of time to delivery than patients with other combinations (adjusted hazard ratio [AHR] 3.2; 95% CI: 1.7, 6.3), whereas patients carrying the C allele of ADCY9 rs2531995, G allele of PDE4B rs598961, and GG genotype of ADRB2 rs1042719 had a lower hazard of time to delivery than patients carrying other genotypes (AHR 0.4; 95% CI: 0.2, 0.7). Regarding ritodrine-induced adverse drug events (ADEs), height less than 160 cm and CC genotype of ADCY9 rs2531995 showed a greater risk of ADEs. The results of our study suggest that ADCY9 polymorphisms could affect the efficacy and safety of \u03b22-adrenergic agonists.<\/jats:p>","DOI":"10.3390\/pharmaceutics13101653","type":"journal-article","created":{"date-parts":[[2021,10,10]],"date-time":"2021-10-10T21:37:29Z","timestamp":1633901849000},"page":"1653","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Association between ADCY9 Gene Polymorphisms and Ritodrine Treatment Outcomes in Patients with Preterm Labor"],"prefix":"10.3390","volume":"13","author":[{"given":"Nari","family":"Lee","sequence":"first","affiliation":[{"name":"College of Pharmacy and Graduate School of Pharmaceutical Sciences, Ewha Womans University, Seoul 03760, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ha-Young","family":"Yoon","sequence":"additional","affiliation":[{"name":"College of Pharmacy and Graduate School of Pharmaceutical Sciences, Ewha Womans University, Seoul 03760, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin-Young","family":"Park","sequence":"additional","affiliation":[{"name":"College of Pharmacy and Graduate School of Pharmaceutical Sciences, Ewha Womans University, Seoul 03760, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3153-3008","authenticated-orcid":false,"given":"Young-Ju","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Ewha Womans University School of Medicine, Seoul 07985, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0622-0701","authenticated-orcid":false,"given":"Han-Sung","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Konkuk University Medical Center, Konkuk University School of Medicine, Seoul 05030, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeong","family":"Yee","sequence":"additional","affiliation":[{"name":"College of Pharmacy and Graduate School of Pharmaceutical Sciences, Ewha Womans University, Seoul 03760, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0278-2563","authenticated-orcid":false,"given":"Hye-Sun","family":"Gwak","sequence":"additional","affiliation":[{"name":"College of Pharmacy and Graduate School of Pharmaceutical Sciences, Ewha Womans University, Seoul 03760, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,10]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2021, August 01).
