Efficacy of CO2 Fractional Laser Combined with Interferon in Treating Persistent High-Risk HPV Infection of the Cervix
-
摘要:
目的 探讨阴道腔内CO2点阵激光联合干扰素治疗宫颈持续性高危型HPV感染的临床疗效及对阴道微生态的影响。 方法 选取2022年6月至2024年7月在昆明市妇幼保健院就诊的211例宫颈持续性高危型HPV感染患者,随机分为随访(空白对照)组(n = 70)、干扰素治疗组(n = 70)和联合治疗组(n = 71)。随访组仅定期随访,干扰素治疗组采用重组人干扰素α-2b治疗,联合治疗组联合CO2点阵激光与干扰素治疗。比较三组治疗3个月、6个月的总有效率、炎症因子水平及阴道微生态恢复情况。 结果 总有效率:联合治疗组3个月、6个月总有效率分别为73.24%和81.69%,高于干扰素组(47.14%、60.00%)和空白对照组(11.43%、18.57%)(均P < 0.001)。炎症因子:治疗后联合治疗组IL-1和TNF-α 水平低于其他两组(P < 0.001)。阴道微生态:联合治疗组PH正常率(84.51%)和乳杆菌正常率(92.96%)优于其他两组(P < 0.001)。 结论 CO2点阵激光联合干扰素可有效清除HPV、改善炎症及阴道微环境,疗效优于单药治疗,安全性良好。 -

Abstract:Objective To investigate the clinical efficacy of intravaginal CO2 fractional laser combined with interferon in treating persistent high-risk HPV infection of the cervix and its impact on vaginal microecology. Methods A total of 211 patients with persistent high-risk HPV infection of the cervix who visited Kunming Maternal and Child Health Care Hospital from June 2022 to July 2024 were selected and randomly divided into a follow-up (blank control) group (n = 70), an interferon treatment group (n = 70), and a combined treatment group (n = 71). The follow-up group received regular follow-ups. The interferon treatment group was treated with recombinant human interferon α-2b, and the combined treatment group received a combination of CO2 matrix laser and interferon treatment. The total effective rate, levels of inflammatory factors, and vaginal microecological recovery were compared among the three groups at 3 and 6 months after treatment. Results Overall efficacy: The overall efficacy rates of the combined treatment group at 3 months and 6 months were 73.24% and 81.69%, respectively, significantly higher than those of the interferon group (47.14% and 60.00%) and the blank control group (11.43% and 18.57%) (all P < 0.001). Inflammatory factors: Post-treatment levels of IL-1 and TNF-α in the combined treatment group were significantly lower than those in the other two groups (P < 0.001). Vaginal microbiota: The combined treatment group had a significantly higher rate of normal PH (84.51%) and normal lactobacillus levels(92.96%) compared to the other two groups (P < 0.001). Conclusion CO2 lattice laser combined with interferon can effectively eliminate HPV, improve inflammation and vaginal microenvironment, and demonstrates superior efficacy to monotherapy, with good safety. -
